Response:

<|channel|>analysis<|message|>We need to summarize the huge text. It's a concatenation of many man pages. The user asks: "summarize". So produce a concise summary of the content: overview of GNU/Linux man pages, intro to commands, getent, iconv, ldd, locale, localedef, memusage, memusagestat, mtrace, pldd, sprof, time, intro to system calls, accept, access, acct, add_key, adjtimex, alarm, alloc_hugepages, arch_prctl, bdflush, bind, bpf, brk, cacheflush, capget, chdir, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll, eventfd, execve, execveat, _exit, exit_group, fallocate... It's huge. Summarize key points: each command/man page description, purpose, usage, options, errors. Provide a brief overview.<|end|><|start|>assistant<|channel|>final<|message|>**Summary – A quick‑look at the most important points from the excerpt**

The text is a long collection of Linux manual‑page excerpts (section 1 for user commands, sections 2‑3 for system calls, etc.).  Below is a concise “cheat‑sheet” that captures the purpose, typical usage and the most relevant options or notes for each entry that appears.

| Topic | What it is / does | Typical use / key options | Important notes / gotchas |
|-------|-------------------|--------------------------|---------------------------|
| **intro(1)** | Introductory manual page for the user‑command section. | Shows basic commands (`date`, `ls`, `cp`, `mv`, `grep`, …) and how to start a shell (`login`, `xterm`). | Emphasises that the CLI is more powerful than the GUI; use `man` for detailed help. |
| **getent(1)** | Prints entries from NSS databases (passwd, group, hosts, …). | `getent passwd` → list users; `getent hosts example.com`. | Uses `/etc/nsswitch.conf`; `--service` overrides source. |
| **iconv(1)** | Convert text between character encodings. | `iconv -f ISO‑8859‑15 -t UTF‑8 < in > out`. | `//TRANSLIT` approximates unknown chars; `//IGNORE` drops them. |
| **ldd(1)** | List shared‑object dependencies of an executable or library. | `ldd /bin/ls`. | Beware: on some systems it may execute the program; use `objdump -p` for a safe alternative. |
| **locale(1)** | Show or set locale‑related environment variables. | `locale -a` → all locales; `locale -c` → show category names. | `LC_ALL` overrides all others; `LANG` is the fallback. |
| **localedef(1)** | Compile locale definition files into binary form (or add to the locale archive). | `localedef -f UTF‑8 -i en_US en_US.UTF‑8`. | Use `--no-archive` to avoid overwriting the system archive; custom locales can be placed under `$HOME/.locale`. |
| **memusage(1)** | Bash script that profiles a program’s heap/stack usage (via `LD_PRELOAD` of `libmemusage.so`). | `memusage -p mem.png ./prog`. | Generates a data file (`-d`) and optional PNG (`-p`). |
| **memusagestat(1)** | Turns a `memusage` data file into a PNG graph. | `memusagestat memusage.dat mem.png`. |
| **mtrace(1)** | Perl script that interprets the malloc‑trace log produced by `mtrace(3)`. | `mtrace ./a.out mtrace.log`. |
| **pldd(1)** | Show the dynamic shared objects linked into a running process (`/proc/<pid>/maps`). | `pldd $$`. |
| **sprof(1)** | Profile a shared library (flat profile, call graph, call‑pair list). | `sprof -p libdemo.so.1 libdemo.so.1.profile`. |
| **time(1)** | Run a command and report elapsed real, user and system CPU time (and many other stats). | `time -p ls`. | GNU version can format output (`-f`) and write to a file (`-o`). |
| **intro(2)** | Introductory page for system‑call section. | Explains that most syscalls have C library wrappers. |
| **accept(2) / accept4(2)** | Accept a pending connection on a listening socket. | `accept4(s, NULL, NULL, SOCK_NONBLOCK|SOCK_CLOEXEC)`. | `accept4` can set `O_NONBLOCK`/`O_CLOEXEC` atomically. |
| **access(2), faccessat(2), faccessat2(2)** | Test a process’s real UID/GID permissions on a pathname. | `access /tmp/file R_OK`. | `faccessat2` adds a true `flags` argument; `access` follows symlinks, `faccessat` can avoid that. |
| **acct(2)** | Turn process accounting on/off (writes per‑process records to a file). | `acct /var/log/pacct`. |
| **add_key(2)** | Create or update a kernel key (used by key‑ring facility). | `add_key user mykey "payload" @s`. |
| **adjtimex(2), clock_adjtime(2), ntp_adjtime(2)** | Tune the kernel clock (NTP discipline, set offset, frequency, etc.). | `adjtimex(&timex)`; `clock_adjtime(CLOCK_REALTIME, &timex)`. |
| **alarm(2)** | Schedule a `SIGALRM` after a number of seconds. | `alarm 10`. |
| **alloc_hugepages(2) / free_hugepages(2)** | Allocate/free “huge” pages (2 MiB/4 MiB) – now obsolete, replaced by `hugetlbfs`. |
| **arch_prctl(2)** | Set/get architecture‑specific thread state on x86‑64 (e.g., FS/GS base, enable/disable CPUID). |
| **bdflush(2)** | Old, deprecated daemon for flushing dirty buffers (no‑op since 2.6). |
| **bind(2)** | Assign a local address to a socket (required before `listen` on stream sockets). |
| **bpf(2)** | System call for creating/managing eBPF maps and programs (load, lookup, update, delete). |
| **brk(2) / sbrk(2)** | Change the program break (old way to allocate memory – use `malloc`). |
| **cacheflush(2)** | Flush instruction and/or data cache (architecture‑specific; use `__builtin___clear_cache`). |
| **capget(2) / capset(2)** | Get/set thread capabilities (low‑level; use libcap wrappers). |
| **chdir(2) / fchdir(2)** | Change the current working directory. |
| **chmod(2) / fchmod(2) / fchmodat(2)** | Change file mode bits (permissions, set‑uid/gid, sticky). |
| **chown(2) / fchown(2) / lchown(2) / fchownat(2)** | Change file ownership (requires CAP_CHOWN). |
| **chroot(2)** | Change the root directory of the calling process (requires CAP_SYS_CHROOT). |
| **clock_getres(2) / clock_gettime(2) / clock_settime(2)** | Query or set various clocks (REALTIME, MONOTONIC, BOOTTIME, …). |
| **clock_nanosleep(2)** | High‑resolution sleep on a chosen clock; can be absolute (`TIMER_ABSTIME`). |
| **clone(2) / clone3(2)** | Create a new process/thread with fine‑grained sharing flags (e.g., `CLONE_VM`, `CLONE_NEWNS`). |
| **close(2)** | Close a file descriptor (note: `close` may return `EINTR` but the descriptor is closed). |
| **close_range(2)** | Close a range of file descriptors in one syscall; can set `CLOEXEC` or `UNSHARE`. |
| **connect(2)** | Initiate a connection on a socket (TCP, UNIX, etc.). |
| **copy_file_range(2)** | In‑kernel copy between two file descriptors (no user‑space buffer). |
| **create_module(2)** | (Removed) Create a loadable kernel module entry (pre‑2.6). |
| **delete_module(2)** | Unload a kernel module (pre‑2.6). |
| **dup(2) / dup2(2) / dup3(2)** | Duplicate a file descriptor; `dup3` can set `O_CLOEXEC`. |
| **epoll_create(2) / epoll_create1(2)** | Create an epoll instance (`EPOLL_CLOEXEC` flag). |
| **epoll_ctl(2)** | Add/modify/delete file descriptors from an epoll interest list (`EPOLL_CTL_*`). |
| **epoll_wait(2) / epoll_pwait(2) / epoll_pwait2(2)** | Wait for events on an epoll instance; can be timed, signal‑masked. |
| **eventfd(2)** | Create a kernel event counter object (read/write 64‑bit integer, can act as semaphore). |
| **execve(2)** | Replace the current process image with a new program (no return on success). Handles set‑uid/gid, interpreter scripts (`#!`). |
| **execveat(2)** | Like `execve` but relative to a directory file descriptor (`AT_EMPTY_PATH`, `AT_SYMLINK_NOFOLLOW`). |
| **_exit(2) / _Exit(2)** | Immediate process termination (no `atexit` handlers, no stdio flushing). |
| **exit_group(2)** | Kernel call used by glibc’s `_exit` to terminate all threads in a process. |
| **fallocate(2)** | Pre‑allocate or de‑allocate space for a file (`FALLOC_FL_KEEP_SIZE`, `FALLOC_FL_PUNCH_HOLE`, …). |

**General take‑aways**

* The man‑pages give a concise description of each command or system call, its syntax, options/flags, return values, possible errors, and notes on portability or security.
* Many of the older interfaces (`bdflush`, `alloc_hugepages`, `create_module`, etc.) are deprecated or removed; modern code should use the newer equivalents (`hugetlbfs`, `delete_module` via `rmmod`, etc.).
* System‑call wrappers in glibc often add extra checks or convenience (e.g., `execveat` uses `execve`‑style semantics but adds `flags`).
* For security‑sensitive operations (e.g., `access`, `chmod`, `chown`, `execve`), the kernel checks real IDs and capabilities; beware of race conditions when checking permissions before opening files.
* The `clone` family is the low‑level primitive for creating threads/processes with fine‑grained sharing; higher‑level libraries (`pthread`) use it under the hood.
* The `epoll` and `eventfd` families provide scalable I/O event notification and simple event counters, respectively, and are heavily used in high‑performance servers.
* The `time` command (and its GNU extensions) is useful for measuring not only elapsed time but also memory usage, page faults, context switches, etc.

This cheat‑sheet should help you quickly locate the relevant manual page, understand the core functionality, and be aware of the most important options and pitfalls for each entry.

<|channel|>analysis<|message|>We need to summarize the content. The content is huge: it's a concatenation of many man pages from Linux. The user asks: "summarize". So we need to produce a concise summary of the entire content.

The content includes:

- Title: GNU/Linux THE MAN-PAGES BOOK
- Maintainers list
- Then a series of man pages: intro(1), locale(1), locale(5), locale(7), locale(8), etc.
- Then many system call man pages: accept, access, acct, add_key, adjtimex, alarm, alloc_hugepages, arch_prctl, bdflush, bind, bpf, brk, cacheflush, capget, chdir, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll_create, epoll_ctl, epoll_wait, eventfd, execve, execveat, _exit, exit_group, fallocate, etc.

But the user likely wants a summary of the entire content? Or maybe just the first part? The prompt says "summarize the above". The above is huge. Probably they want a concise summary of the whole thing: it's a collection of Linux man pages covering a wide range of topics: introduction to commands, locale handling, system calls, etc.

Thus answer: a summary of the content: it's a collection of manual pages for Linux commands and system calls, covering topics like intro to user commands, locale settings, system calls like accept, access, acct, add_key, adjtimex, alarm, arch_prctl, bdflush, bind, bpf, brk, cacheflush, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll, eventfd, execve, execveat, etc. It includes descriptions, usage, options, return values, errors, notes, examples.

Thus answer summarizing each major section: intro to commands, locale command usage, system calls overview, specific system calls details.

Probably they want a concise summary: The document is a collection of Linux manual pages covering user commands (like ls, cp, mv, grep), system calls (like accept, access, bind, clone, execve), and utilities (like ldd, locale, iconv, etc.), with sections on each command's name, synopsis, description, options, return values, errors, notes, examples, and references.

Thus answer: The text is a compilation of many Linux man pages, including an introduction to user commands, details on locale handling, and extensive documentation of system calls such as accept, access, acct, add_key, adjtimex, alarm, arch_prctl, bdflush, bind, bpf, brk, cacheflush, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll, eventfd, execve, execveat, etc., each with description, usage, options, return values, errors, notes, and examples. Also includes sections on using the command line, file system navigation, process management, and system utilities like ldd, locale, iconv, memusage, etc.

Thus final answer summarizing that.<|end|><|start|>assistant<|channel|>final<|message|>**Summary**

The document you provided is a compilation of many GNU/Linux manual pages (the “man‑pages” collection). It includes:

* **Introductory material** – An overview of the Linux user environment, including logging in, using the shell, basic commands (`date`, `cal`, `ls`, `cp`, `mv`, `rm`, `grep`, etc.), navigating the filesystem, and using the command‑line interface versus a graphical UI. It also points out where to find further documentation (e.g., `man` pages, info pages, HOWTOs).

* **Locale utilities** – Documentation for the `locale` command (viewing and setting locale information), the `locale` family of environment variables, and related tools (`localedef`, `iconv`). It explains how to list locales, view character maps, and set locale‑specific environment variables.

* **System utilities** – Descriptions of many standard commands such as `getent`, `ldd`, `ld.so`, `ldconfig`, `memusage`, `memusagestat`, `mtrace`, `time`, etc., covering their purpose, usage syntax, options, and examples.

* **System call reference** – The core **Section 2** of the manual, detailing low‑level kernel interfaces. For each call (e.g., `accept`, `access`, `acct`, `add_key`, `adjtimex`, `alarm`, `arch_prctl`, `bdflush`, `bind`, `bpf`, `brk`, `cacheflush`, `chmod`, `chown`, `chroot`, `clock_getres`, `clock_nanosleep`, `clone`, `close`, `close_range`, `connect`, `copy_file_range`, `create_module`, `delete_module`, `dup`, `epoll_create`, `epoll_ctl`, `epoll_wait`, `eventfd`, `execve`, `execveat`, `_exit`, `exit_group`, `fallocate`, etc.) are described with:

  * **Synopsis** – Function prototypes and required headers.
  * **Description** – What the call does and its typical usage.
  * **Parameters** – Meaning of each argument.
  * **Return values** – Success and error codes.
  * **Error handling** – Possible `errno` values and their meanings.
  * **Notes** – Special considerations, kernel behavior, and differences from other OSes.
  * **Examples** – Sample code snippets demonstrating usage.
  * **Compatibility** – Information on standards compliance and kernel version requirements.
  * **Related commands** – Cross‑references to related system calls and utilities.

Overall, the collection serves as a comprehensive reference for developers and system administrators working with Linux, covering everything from everyday command‑line tools to low‑level kernel interfaces, complete with usage examples, options, and detailed technical notes.

[ggerganov]

Hm, the fact that the response is different in the 2 tests when using --temp 0 is indeed suspicious.

@aendk Attention here - could be a regression due to #17795

In the meantime, @mxxm-t can you confirm that reverting 2cd20b7 fixes the issue?

[mxxm-t]

Compiled all form clean source. Also I am running these tests on Radeon MI50 with ROCm 7.2 and Radeon MI50 is not officaily supported on ROCm 7.2 so it might play some role but probably not.

Same command for all tests:

The text is a long collection of Linux manual‑page excerpts (section 1 for user commands, sections 2‑3 for system calls and library functions).  Below is a concise “cheat‑sheet” that captures the purpose, typical usage and the most relevant options or behaviours of each entry.

| Topic | What it is / does | Typical use / key options |
|-------|-------------------|--------------------------|
| **intro(1)** | Introductory guide to the user‑command environment (shell, login, basic utilities). | Shows a minimal session: login → shell → commands like `date`, `ls`, `cp`, `mv`, `grep`. |
| **getent(1)** | Prints entries from NSS databases (passwd, group, hosts, …). | `getent passwd` → list users; `getent hosts example.com` → DNS lookup. |
| **iconv(1)** | Convert text between character encodings. | `iconv -f ISO‑8859‑15 -t UTF‑8 < in > out`; `//TRANSLIT` to approximate unmappable chars. |
| **ldd(1)** | List shared‑object dependencies of an executable or library. | `ldd /bin/ls`; beware of security risk on untrusted binaries. |
| **locale(1)** | Show or set locale‑related environment values. | `locale -a` → all locales; `locale -c charmap` → current charset. |
| **localedef(1)** | Compile locale definition files into binary form (or add to the locale archive). | `localedef -f UTF‑8 -i en_US en_US.UTF‑8`. |
| **memusage(1)** | Bash wrapper that profiles a program’s heap/stack usage (via `libmemusage.so`). | `memusage -p mem.png ./prog`; produces a PNG graph with `memusagestat`. |
| **memusagestat(1)** | Turns the data file produced by `memusage` into a PNG graph. |
| **mtrace(1)** | Perl script that interprets the malloc‑trace log created by `mtrace(3)`. |
| **pldd(1)** | Show the list of shared objects that a running process has loaded. |
| **sprof(1)** | Profile a shared library (flat profile, call graph, call‑pair list). |
| **time(1)** | Run a command and report elapsed real, user and system CPU time (and many other stats with `-f`). |
| **intro(2)** | Intro to system‑call programming; most calls have libc wrappers. |
| **accept(2) / accept4(2)** | Accept a pending connection on a listening socket; `accept4` can set `O_NONBLOCK` and `O_CLOEXEC`. |
| **access(2), faccessat(2), faccessat2(2)** | Test a process’s real‑UID/GID permissions on a pathname; newer `faccessat2` adds flag support. |
| **acct(2)** | Turn process accounting on/off (writes a record for each terminated process). |
| **add_key(2)** | Create or update a kernel key (used by keyrings, user‑key, logon‑key, etc.). |
| **adjtimex(2), clock_adjtime(2), ntp_adjtime(2)** | Query or set kernel clock parameters (NTP discipline, frequency, leap‑second handling). |
| **alarm(2)** | Schedule a `SIGALRM` after a given number of seconds. |
| **alloc_hugepages(2) / free_hugepages(2)** | (Deprecated) Allocate/free “huge” pages (2 MiB/4 MiB) on i386/ia64. |
| **arch_prctl(2)** | Set/get architecture‑specific thread state on x86‑64 (e.g. FS/GS base, CPUID faulting). |
| **bdflush(2)** | (Deprecated) Directly control the buffer‑dirty‑flush daemon. |
| **bind(2)** | Assign a local address to a socket (required before `listen` on stream sockets). |
| **bpf(2)** | Core system call for eBPF: create maps, load programs, manipulate maps, etc. |
| **brk(2) / sbrk(2)** | Adjust the program break (old‑style heap allocation – use `malloc` instead). |
| **cacheflush(2)** | Flush instruction and/or data caches (architecture‑specific; usually use `__builtin___clear_cache`). |
| **capget(2) / capset(2)** | Low‑level get/set of thread capabilities (use libcap instead). |
| **chdir(2) / fchdir(2)** | Change the current working directory (by pathname or by FD). |
| **chmod(2) / fchmod(2) / fchmodat(2)** | Change file mode bits (permissions, set‑uid/gid, sticky). |
| **chown(2) / fchown(2) / lchown(2) / fchownat(2)** | Change file ownership (UID/GID). |
| **chroot(2)** | Change the root directory of the calling process (used for “jails”). |
| **clock_getres(2) / clock_gettime(2) / clock_settime(2)** | Query resolution, read, or set various clocks (REALTIME, MONOTONIC, TAI, …). |
| **clock_nanosleep(2)** | High‑resolution sleep on a chosen clock; can be absolute (`TIMER_ABSTIME`). |
| **clone(2) / clone3(2)** | Create a new process/thread with fine‑grained sharing flags (CLONE_VM, CLONE_FS, CLONE_NEWNS, …). |
| **close(2)** | Close a file descriptor (note: errors are not always fatal; `close` may block on I/O). |
| **close_range(2)** | Close a range of file descriptors in one syscall (optionally set `CLOEXEC`). |
| **connect(2)** | Initiate a connection on a socket (TCP, UNIX, etc.). |
| **copy_file_range(2)** | Kernel‑side copy between two regular files without moving data to user space. |
| **create_module(2)** | (Removed) Create a loadable kernel module entry (pre‑2.6 kernels). |
| **delete_module(2)** | (Removed) Unload a kernel module. |
| **dup(2) / dup2(2) / dup3(2)** | Duplicate a file descriptor; `dup3` can set `O_CLOEXEC`. |
| **epoll_create(2) / epoll_create1(2)** | Create an epoll instance (event‑notification facility). |
| **epoll_ctl(2)** | Add/modify/delete file descriptors in an epoll interest list. |
| **epoll_wait(2) / epoll_pwait(2) / epoll_pwait2(2)** | Wait for events on an epoll instance (with optional timeout and signal mask). |
| **eventfd(2)** | Create a counter‑based event‑notification FD (read/write 64‑bit integer). |
| **execve(2)** | Replace the current process image with a new program (the core `exec` call). |
| **execveat(2)** | Like `execve` but relative to a directory FD (or empty‑path execution). |
| **_exit(2) / _Exit(2)** | Immediate process termination without running atexit handlers. |
| **exit_group(2)** | Kernel call used by `_exit` to terminate all threads in a process. |
| **fallocate(2)** | Pre‑allocate or de‑allocate space for a file (e.g. `FALLOC_FL_KEEP_SIZE`). |

**Common Themes & Take‑aways**

* **Security** – Many calls (e.g. `ldd`, `close_range`, `execve`, `accept`) have security considerations (e.g. avoid executing untrusted binaries, beware of race conditions, set `CLOEXEC` where appropriate).
* **Flags & Modes** – Almost every syscall has a set of flags that control its exact behaviour (e.g. `clone` sharing flags, `open`/`openat` flags, `bpf` map types, `fallocate` modes).  Understanding the flag semantics is essential.
* **Error handling** – Errors are reported via `-1` and `errno`.  Man pages list the possible `errno` values; many calls have special cases (e.g. `EAGAIN` on non‑blocking sockets, `EINTR` on interrupted syscalls).
* **Deprecation** – Some older interfaces (`bdflush`, `alloc_hugepages`, `create_module`, `delete_module`) are deprecated or removed; newer alternatives exist.
* **Performance‑oriented syscalls** – `copy_file_range`, `splice`, `sendfile`, `eventfd`, `epoll` provide zero‑copy or efficient event handling.
* **Thread & process creation** – `clone`/`clone3` give fine‑grained control over what is shared; `fork` is a special case of `clone`.
* **Time & clocks** – Linux provides many clocks (`REALTIME`, `MONOTONIC`, `BOOTTIME`, `TAI`, per‑thread/process CPU clocks) and related syscalls (`clock_gettime`, `clock_nanosleep`, `adjtimex`).

This overview should give you a quick reference to the purpose and most important aspects of each command or system call covered in the excerpt. For detailed syntax, options, and error codes, consult the individual man pages.

The text is a long collection of Linux manual‑page excerpts (section 1 for user commands, sections 2‑3 for system calls, etc.).  Below is a concise “cheat‑sheet” that captures the purpose, typical usage and the most relevant options or notes for each entry that appears.

| Topic | What it is / does | Typical use / key options | Important notes / gotchas |
|-------|-------------------|--------------------------|---------------------------|
| **intro(1)** | Introductory manual page for the user‑command section. | Shows basic commands (`date`, `ls`, `cp`, `mv`, `grep`, …) and how to start a shell (`login`, `xterm`). | Emphasises that the CLI is more powerful than the GUI; use `man` for detailed help. |
| **getent(1)** | Prints entries from NSS databases (passwd, group, hosts, …). | `getent passwd` → list users; `getent hosts example.com`. | Uses `/etc/nsswitch.conf`; `--service` overrides source. |
| **iconv(1)** | Convert text between character encodings. | `iconv -f ISO‑8859‑15 -t UTF‑8 < in > out`. | `//TRANSLIT` approximates unknown chars; `//IGNORE` drops them. |
| **ldd(1)** | List shared‑object dependencies of an executable or library. | `ldd /bin/ls`. | Beware: on some systems it may execute the program; use `objdump -p` for a safe alternative. |
| **locale(1)** | Show or set locale‑related environment variables. | `locale -a` → all locales; `locale -c` → show category names. | `LC_ALL` overrides all others; `LANG` is the fallback. |
| **localedef(1)** | Compile locale definition files into binary form (or add to the locale archive). | `localedef -f UTF‑8 -i en_US en_US.UTF‑8`. | Use `--no-archive` to avoid overwriting the system archive; custom locales can be placed under `$HOME/.locale`. |
| **memusage(1)** | Bash script that profiles a program’s heap/stack usage (via `LD_PRELOAD` of `libmemusage.so`). | `memusage -p mem.png ./prog`. | Generates a data file (`-d`) and optional PNG (`-p`). |

| **accept(2) / accept4(2)** | Accept a pending connection on a listening socket. | `accept4(s, NULL, NULL, SOCK_NONBLOCK|SOCK_CLOEXEC)`. | `accept4` can set `O_NONBLOCK`/`O_CLOEXEC` atomically. |
| **access(2), faccessat(2), faccessat2(2)** | Test a process’s real UID/GID permissions on a pathname. | `access /tmp/file R_OK`. | `faccessat2` adds a true `flags` argument; `access` follows symlinks, `faccessat` can avoid that. |

| **create_module(2)** | (Removed) Create a loadable kernel module entry (pre‑2.6). |
| **delete_module(2)** | Unload a kernel module (pre‑2.6). |
| **dup(2) / dup2(2) / dup3(2)** | Duplicate a file descriptor; `dup3` can set `O_CLOEXEC`. |
| **epoll_create(2) / epoll_create1(2)** | Create an epoll instance (`EPOLL_CLOEXEC` flag). |

**General take‑aways**

* The man‑pages give a concise description of each command or system call, its syntax, options/flags, return values, possible errors, and notes on portability or security.
* Many of the older interfaces (`bdflush`, `alloc_hugepages`, `create_module`, etc.) are deprecated or removed; modern code should use the newer equivalents (`hugetlbfs`, `delete_module` via `rmmod`, etc.).
* System‑call wrappers in glibc often add extra checks or convenience (e.g., `execveat` uses `execve`‑style semantics but adds `flags`).
* For security‑sensitive operations (e.g., `access`, `chmod`, `chown`, `execve`), the kernel checks real IDs and capabilities; beware of race conditions when checking permissions before opening files.
* The `clone` family is the low‑level primitive for creating threads/processes with fine‑grained sharing; higher‑level libraries (`pthread`) use it under the hood.
* The `epoll` and `eventfd` families provide scalable I/O event notification and simple event counters, respectively, and are heavily used in high‑performance servers.
* The `time` command (and its GNU extensions) is useful for measuring not only elapsed time but also memory usage, page faults, context switches, etc.

This cheat‑sheet should help you quickly locate the relevant manual page, understand the core functionality, and be aware of the most important options and pitfalls for each entry.

<|channel|>analysis<|message|>We need to summarize the content. The content is huge: it's a concatenation of many man pages from Linux. The user asks: "summarize". So we need to produce a concise summary of the entire content.

The content includes:

- Title: GNU/Linux THE MAN-PAGES BOOK
- Maintainers list
- Then a series of man pages: intro(1), locale(1), locale(5), locale(7), locale(8), etc.
- Then many system call man pages: accept, access, acct, add_key, adjtimex, alarm, alloc_hugepages, arch_prctl, bdflush, bind, bpf, brk, cacheflush, capget, chdir, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll_create, epoll_ctl, epoll_wait, eventfd, execve, execveat, _exit, exit_group, fallocate, etc.

But the user likely wants a summary of the entire content? Or maybe just the first part? The prompt says "summarize the above". The above is huge. Probably they want a concise summary of the whole thing: it's a collection of Linux man pages covering a wide range of topics: introduction to commands, locale handling, system calls, etc.

Thus answer: a summary of the content: it's a collection of manual pages for Linux commands and system calls, covering topics like intro to user commands, locale settings, system calls like accept, access, acct, add_key, adjtimex, alarm, arch_prctl, bdflush, bind, bpf, brk, cacheflush, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll, eventfd, execve, execveat, etc. It includes descriptions, usage, options, return values, errors, notes, examples.

Thus answer summarizing each major section: intro to commands, locale command usage, system calls overview, specific system calls details.

Probably they want a concise summary: The document is a collection of Linux manual pages covering user commands (like ls, cp, mv, grep), system calls (like accept, access, chmod, etc.), and utilities (like ldd, locale, iconv, etc.). It includes sections on each command's name, synopsis, description, options, return values, errors, notes, examples, and related commands.

It also includes information about the GNU/Linux environment, login, shell usage, file system navigation, and process management.

Thus answer summarizing the whole.<|end|><|start|>assistant<|channel|>final<|message|>**Summary**

The text is a compilation of many GNU/Linux manual pages (the “man‑pages” collection) that together provide a comprehensive reference for the operating system’s user‑level commands, utilities, and kernel system‑call interfaces. It includes:

* **Introductory material** – Overview of the Linux environment, the role of the shell, basic navigation (`cd`, `pwd`, `ls`), file manipulation (`cp`, `mv`, `rm`, `mkdir`, `rmdir`), and basic command‑line usage (e.g., `login`, `man`, `info`). It also explains the difference between GUIs and CLI, the purpose of the `$PATH`, and how to use the terminal.

* **Locale utilities** – Documentation for `locale`, `localedef`, `iconv`, and related tools, covering how to view, set, and list locale information, character maps, and environment variables that affect locale.

* **System utilities** – Descriptions of commands such as `ldd` (list shared‑object dependencies), `ldconfig`, `ld.so`, `ldd`, `ldd` options, `getent` (retrieve entries from Name Service Switch), `ldd` (list shared libraries), `ld.so` loader, `ldd` debugging notes, and more.

* **System call reference** – Detailed pages for many Linux kernel system calls, each with synopsis, description, arguments, return values, possible errors, notes on behavior, and usage examples. Highlights include:
  - **File and directory operations**: `open`, `read`, `write`, `close`, `stat`, `chmod`, `chown`, `chmod`, `mkdir`, `rmdir`, `unlink`, `rename`, `link`, `symlink`, `chmod`, `chown`, `chmod`.

<|channel|>analysis<|message|>We need to summarize the content. The content is huge: it's a concatenation of many man pages from Linux. The user asks: "summarize". So we need to produce a concise summary of the entire content.

The content includes:

- Title: GNU/Linux THE MAN-PAGES BOOK
- Maintainers list
- Then a series of man pages: intro(1), locale(1), locale(5), locale(7), locale(8), etc.
- Then many system call man pages: accept, access, acct, add_key, adjtimex, alarm, alloc_hugepages, arch_prctl, bdflush, bind, bpf, brk, cacheflush, capget, chdir, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll_create, epoll_ctl, epoll_wait, eventfd, execve, execveat, _exit, exit_group, fallocate, etc.

But the question: "summarize". Probably they want a concise summary of the whole document? Or maybe they want a summary of the content we see? The content is huge; summarizing everything would be a massive summary. But maybe they want a summary of the whole "GNU/Linux THE MAN-PAGES BOOK"? Or maybe they want a summary of the entire text? Usually these tasks ask to summarize the given text. So we need to produce a concise summary that captures the main points: the document is a collection of Linux manual pages covering a wide range of topics: introduction to user commands, locale handling, system calls like accept, access, acct, add_key, adjtimex, alarm, arch_prctl, bdflush, bind, bpf, brk, cacheflush, capget, chdir, chmod, chown, chroot, clock_getres, clock_nanosleep, clone, close, close_range, connect, copy_file_range, create_module, delete_module, dup, epoll, eventfd, execve, execveat, etc.

Thus the summary: The document is a compilation of Linux man pages covering user commands (intro, locale, getent, iconv, ldd, etc.) and system calls (accept, access, acct, add_key, adjtimex, alarm, arch_prctl, bdflush, bind, bpf, brk, cacheflush, chmod, chown, chroot, clock_gettime, clone, close, epoll, execve, etc.) It includes descriptions, usage, options, return values, errors, notes, and examples for each command and system call.

Thus answer: a summary of the content: It's a comprehensive reference for Linux commands and system calls, covering topics like file management, process control, networking, system configuration, system calls for file operations, process control, memory management, security, and more. It includes sections on user commands (like ls, cp, mv, grep), locale settings, system calls for file access, process creation, memory allocation, network sockets, etc., with detailed descriptions, options, return values, errors, and examples.

Thus answer accordingly.<|end|><|start|>assistant<|channel|>final<|message|>**Summary of the Provided Document**

@mxxm-t so reverting to 2cd20b7 fixes the issue?

I reverted 2cd20b7 then it worked (first two tests).
Also retested 2cd20b7 (last two tests) but this time those didn't finish at all because of response loop.

Also testing few cases that i suspect might break it.

[aendk]

@mxxm-t I think you have a typo there.

You tested before/after and the "before" case (reverting 2cd20b7) worked all the time, whereas the "after", the current master release, always fails for various reasons?

Can you retest using officially supported ROCm?

Alternatively, in ggml-cuda.cu Line ~2827, can you exchange
bool copy_from_host = ggml_backend_buffer_is_host(buf_src) && ggml_backend_dev_type(backend_src->device) == GGML_BACKEND_DEVICE_TYPE_CPU;
with
bool copy_from_host = false;
recompile, and then retest?

With this code change it works but since transfers are blocking now the performance dropped ~4x.

Provide a brief overview.<|end|><|start|>assistant<|channel|>final<|message|>**Summary – A quick‑look at the most important points from the excerpt**

The text is a long collection of Linux manual‑page excerpts (section 1 for user commands, sections 2‑3 for system calls, etc.). Below is a concise “cheat‑sheet” that captures the purpose, typical usage and the most relevant options or notes for each entry that appears.

Topic	What it is / does	Typical use / key options	Important notes / gotchas
intro(1)	Introductory manual page for the user‑command section.	Shows basic commands (date, ls, cp, mv, grep, …) and how to start a shell (login, xterm).	Emphasises that the CLI is more powerful than the GUI; use man for detailed help.
getent(1)	Prints entries from NSS databases (passwd, group, hosts, …).	getent passwd → list users; getent hosts example.com.	Uses /etc/nsswitch.conf; --service overrides source.
iconv(1)	Convert text between character encodings.	iconv -f ISO‑8859‑15 -t UTF‑8 < in > out.	//TRANSLIT approximates unknown chars; //IGNORE drops them.
ldd(1)	List shared‑object dependencies of an executable or library.	ldd /bin/ls.	Beware: on some systems it may execute the program; use objdump -p for a safe alternative.
locale(1)	Show or set locale‑related environment variables.	locale -a → all locales; locale -c → show category names.	LC_ALL overrides all others; LANG is the fallback.
localedef(1)	Compile locale definition files into binary form (or add to the locale archive).	localedef -f UTF‑8 -i en_US en_US.UTF‑8.	Use --no-archive to avoid overwriting the system archive; custom locales can be placed under $HOME/.locale.
memusage(1)	Bash script that profiles a program’s heap/stack usage (via LD_PRELOAD of libmemusage.so).	memusage -p mem.png ./prog.	Generates a data file (-d) and optional PNG (-p).
memusagestat(1)	Turns a memusage data file into a PNG graph.	memusagestat memusage.dat mem.png.
pldd(1)	Show the dynamic shared objects linked into a running process (/proc/<pid>/maps).	pldd $$.
sprof(1)	Profile a shared library (flat profile, call graph, call‑pair list).	sprof -p libdemo.so.1 libdemo.so.1.profile.
time(1)	Run a command and report elapsed real, user and system CPU time (and many other stats).	time -p ls.	GNU version can format output (-f) and write to a file (-o).
intro(2)	Introductory page for system‑call section.	Explains that most syscalls have C library wrappers.
accept(2) / accept4(2)	Accept a pending connection on a listening socket.	`accept4(s, NULL, NULL, SOCK_NONBLOCK	SOCK_CLOEXEC)`.
access(2), faccessat(2), faccessat2(2)	Test a process’s real UID/GID permissions on a pathname.	access /tmp/file R_OK.	faccessat2 adds a true flags argument; access follows symlinks, faccessat can avoid that.
acct(2)	Turn process accounting on/off (writes per‑process records to a file).	acct /var/log/pacct.
add_key(2)	Create or update a kernel key (used by key‑ring facility).	add_key user mykey "payload" @s.
adjtimex(2), clock_adjtime(2), ntp_adjtime(2)	Tune the kernel clock (NTP discipline, set offset, frequency, etc.).	adjtimex(&timex); clock_adjtime(CLOCK_REALTIME, &timex).
alarm(2)	Schedule a SIGALRM after a number of seconds.	alarm 10.
alloc_hugepages(2) / free_hugepages(2)	Allocate/free “huge” pages (2 MiB/4 MiB) – now obsolete, replaced by hugetlbfs.
arch_prctl(2)	Set/get architecture‑specific thread state on x86‑64 (e.g., FS/GS base, enable/disable CPUID).
bdflush(2)	Old, deprecated daemon for flushing dirty buffers (no‑op since 2.6).
bind(2)	Assign a local address to a socket (required before listen on stream sockets).
bpf(2)	System call for creating/managing eBPF maps and programs (load, lookup, update, delete).
brk(2) / sbrk(2)	Change the program break (old way to allocate memory – use malloc).
cacheflush(2)	Flush instruction and/or data cache (architecture‑specific; use __builtin___clear_cache).
capget(2) / capset(2)	Get/set thread capabilities (low‑level; use libcap wrappers).
chdir(2) / fchdir(2)	Change the current working directory.
chmod(2) / fchmod(2) / fchmodat(2)	Change file mode bits (permissions, set‑uid/gid, sticky).
chown(2) / fchown(2) / lchown(2) / fchownat(2)	Change file ownership (requires CAP_CHOWN).
chroot(2)	Change the root directory of the calling process (requires CAP_SYS_CHROOT).
clock_getres(2) / clock_gettime(2) / clock_settime(2)	Query or set various clocks (REALTIME, MONOTONIC, BOOTTIME, …).
clock_nanosleep(2)	High‑resolution sleep on a chosen clock; can be absolute (TIMER_ABSTIME).
clone(2) / clone3(2)	Create a new process/thread with fine‑grained sharing flags (e.g., CLONE_VM, CLONE_NEWNS).
close(2)	Close a file descriptor (note: close may return EINTR but the descriptor is closed).
close_range(2)	Close a range of file descriptors in one syscall; can set CLOEXEC or UNSHARE.
connect(2)	Initiate a connection on a socket (TCP, UNIX, etc.).
copy_file_range(2)	In‑kernel copy between two file descriptors (no user‑space buffer).
create_module(2)	(Removed) Create a loadable kernel module entry (pre‑2.6).
delete_module(2)	Unload a kernel module (pre‑2.6).
dup(2) / dup2(2) / dup3(2)	Duplicate a file descriptor; dup3 can set O_CLOEXEC.
epoll_create(2) / epoll_create1(2)	Create an epoll instance (EPOLL_CLOEXEC flag).
epoll_ctl(2)	Add/modify/delete file descriptors from an epoll interest list (EPOLL_CTL_*).
epoll_wait(2) / epoll_pwait(2) / epoll_pwait2(2)	Wait for events on an epoll instance; can be timed, signal‑masked.
eventfd(2)	Create a kernel event counter object (read/write 64‑bit integer, can act as semaphore).
execve(2)	Replace the current process image with a new program (no return on success). Handles set‑uid/gid, interpreter scripts (#!).
execveat(2)	Like execve but relative to a directory file descriptor (AT_EMPTY_PATH, AT_SYMLINK_NOFOLLOW).
_exit(2) / _Exit(2)	Immediate process termination (no atexit handlers, no stdio flushing).
exit_group(2)	Kernel call used by glibc’s _exit to terminate all threads in a process.
fallocate(2)	Pre‑allocate or de‑allocate space for a file (FALLOC_FL_KEEP_SIZE, FALLOC_FL_PUNCH_HOLE, …).

General take‑aways

• The man‑pages give a concise description of each command or system call, its syntax, options/flags, return values, possible errors, and notes on portability or security.
• Many of the older interfaces (bdflush, alloc_hugepages, create_module, etc.) are deprecated or removed; modern code should use the newer equivalents (hugetlbfs, delete_module via rmmod, etc.).
• System‑call wrappers in glibc often add extra checks or convenience (e.g., execveat uses execve‑style semantics but adds flags).
• For security‑sensitive operations (e.g., access, chmod, chown, execve), the kernel checks real IDs and capabilities; beware of race conditions when checking permissions before opening files.
• The clone family is the low‑level primitive for creating threads/processes with fine‑grained sharing; higher‑level libraries (pthread) use it under the hood.
• The epoll and eventfd families provide scalable I/O event notification and simple event counters, respectively, and are heavily used in high‑performance servers.
• The time command (and its GNU extensions) is useful for measuring not only elapsed time but also memory usage, page faults, context switches, etc.

This cheat‑sheet should help you quickly locate the relevant manual page, understand the core functionality, and be aware of the most important options and pitfalls for each entry.

give me first sentence of this text

First sentence of the whole text: It starts with "GNU/Linux THE MAN-PAGES BOOK Maintainers: ..." Actually first line: "GNU/Linux THE MAN-PAGES BOOK". That's a title, not a sentence. Next line: "Maintainers: Alejandro Colomar alx@kernel.org 2020 - present (5.09 - HEAD)". That's not a sentence. Then "Michael Kerrisk mtk.manpages@gmail.com 2004 - 2021 (2.00 - 5.13)".

Can you give us more details on your setup, e.g. do you use all 10 GPUs with pipeline parallelism?
Do you have any other launch parameters except the ones shown in your comments?
Can you share how you compile?

Implementing bool copy_from_host = false; disables one of two features introduced in 2cd20b7, enabling syncless CPU-> GPU transfers for CUDA.
This should not reduce performance by 4x, I expect a performance drop of ~1% at most (on linux).

If you see a 4x reduction, have you seen any meaningful performance increases and decreases in your previous tests before and after 2cd20b7 ?

After 2cd20b7 the test is about 2083pp tps, so minor drop.

This code change breaks pipeline parallelism.
Normally when pipeline parallelism is enabled and working correctly I see 4-5 GPUs working out of 10 at time after this change 8 GPU's are idle, one GPU is working (100% GPU usage and about ~200w power usage) and one is in "waiting state" (100% GPU usage and ~20W power usage).
