This commit shortens register-indexed load/store emitter functions, by reusing integer-indexed equivalent operations as part of the sequence generation process. Before these changes, register-indexed load/store emitters would follow two steps to generate the sequence: generate opcodes to fix up the register offset to make it point to the exact position in memory where the operation should take place, and then perform the load/store operation itself using 0 as an offset from the recalculated address register. Since there is already a generic optimised emitter for integer-indexed load/stores, that bit of code can be reused rather than having an ad-hoc implementation that is tailored to operate on an offset of 0. Removing the custom emitter code in favour of calling the general integer-indexed emitter saves around 150 bytes without any changes in the emitter behaviour (generating the same opcode sequence and making use of future improvement in that emitter too).

This commit changes the sequences generated for not-equal and less-than-or-equal comparisons, in favour of better replacements. The new not-equal comparison generates a sequence of equal size but without the burden of a jump to set the output value, this also had the effect of reducing the size of the code generator as only two opcodes need to be generated instead of three. The less-than-or-equal sequence, on the other hand, is actually two bytes shorter and does not contain any jumps. If Zcb opcodes can be used for performing the final XOR operation then two more bytes could be saved on each comparison. The same remarks about having a shorter generator due to two opcodes being generated instead of three still applies here. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>

This commit lets the native emitter generate shorter code when clearing exception objects on RV32. Since there are no direct generic ASM functions to set a specific immediate to a local variable, the native emitter usually generates an immediate assignment to a temporary register and then a store of that register into the chosen local variable. This pattern is also followed when clearing certain local variables related to exception handling, using MP_OBJ_NULL as the immediate value to set. Given that at the moment MP_OBJ_NULL is defined to be 0 (with some other spots in the native emitter that leverage that fact when checking the state of the variables mentioned earlier), and that the RV32 CPU has a dedicated register that is hardwired to read 0, a new method to set local variables to MP_OBJ_NULL is introduced. When generating RV32 code, the new macro will skip the intermediate register assignment and directly uses the X0/ZERO register to set the chosen local variable to MP_OBJ_NULL. Other platforms will still generate the same code sequence as before this change. This is a followup to 40585ea. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>

Add abort setup code `nlr_set_abort` to the standard runtime executor. This makes the standard runtime respond to abort signal without any further modifications. - When aborted, the program exits with 137 exit code (configurable, same as posix sig abort), to differentiate from a normal shutdown. - When exited by exception/crash, the program will exit with exit code 1 (configurable). - When exited by exception KeyboardInterrupt, the program will exit with exit code 130 (configurable, same as posix sig int). - When exited with a exit code (from Python environment), this code is propagated. When a different object is passed, exit code is set to 1 and the value printed, to be consistent with Python docs: https://python.readthedocs.io/en/latest/library/exceptions.html#SystemExit Signed-off-by: John Smith <jsmith@jsmith.cz>

The current `esp32.RMT` class uses a legacy API from ESP-IDF 4.x. The ESP-IDF 5.x offers a new API, which is overall better, and easier to implement the RX side in the future. This commit updates the module and the documentation, preserving the current MicroPython RMT API as much as possible. The bitstream RMT implementation was updated as well, since ESP-IDF does not allow firmware to reference legacy and new APIs at the same time (it resets right after boot with an error message, even if neither module is imported). The documentation is updated accordingly. Signed-off-by: Elvis Pfutzenreuter <elvis.pfutzenreuter@gmail.com>

Not a functional change, but makes it easier to see that mp_usbd_init() is available regardless of whether MICROPY_HW_ENABLE_USB_RUNTIME_DEVICE is set. Also adds a no-op inline mp_usbd_deinit() implementation, which means both a port's calls to mp_usbd_init()/deinit() can both be guarded on the same MICROPY_HW_ENABLE_USBDEV.

Fixes problems with USB-CDC state after soft reset if USBDevice has been active with the default USB-CDC driver also enabled. This also brings ESP32 behaviour in line with RP2 and other ports, where boot.py is executed before the runtime USB device is initialised. This allows setting up a custom USB device in boot.py. There is still a bug here, because calling tud_disconnect() doesn't cause any UNPLUG or BUS_RESET events to arrive from TinyUSB - which means the USB device state stays out of sync until we call mp_usbd_init() again...

This is necessary so the ESP-IDF TinyUSB component can include py/mpconfig.h, but is also a good design goal (less creep of symbols into unrelated parts of the code). This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
Instead, depend directly on espressif/tinyusb component (which is otherwise transitively included via esp_tinyusb). Turns out esp_tinyusb builds a bunch of source files with symbols that conflict with our tinyusb symbols (i.e. descriptors_control.c). This only works because nothing in MicroPython causes the linker to include the esp_tinyusb.a library, however in order to override the dcd_int_handler (in following commit) this caused the linker to pull this library in and break the build. There's also a problematic header skew - TinyUSB component was building with the tusb_config.h file from esp_tinyusb component, but we have our own tusb_config.h file in shared/tinyusb. The changes in parent commit allow us to build the TinyUSB component with our tusb_config.h header. User-facing impacts are: - Can no longer override USB VID & PID via sdkconfig, have to set MICROPY_HW_USB_VID/PID instead (changes applied in this commit). - esp32 boards will have the same USB serial number as other ports (i.e. based on the hardware MAC address, not hard-coded). Side effects include: - CFG_TUD_DWC2_SLAVE_ENABLE is now set, DMA mode is disabled. Signed-off-by: Angus Gratton <angus@redyak.com.au>

If MICROPY_PY_THREAD is set, PendSV_Handler acquires a mutex and calls the dispatch functions. If pendsv_schedule_dispatch is called by a higher priority interrupt while the mutex is acquired by PendSV_Handler it's possible for the dispatch to not be triggered.

This commit fixes a long standing bug/deficiency in the lwIP socket code, whereby it would abandon all incoming TCP data if the remote sent a TCP RST. This behaviour it tested by the existing `tests/multi_net/tcp_client_rst.py` and `tests/multi_net/asyncio_tcp_client_rst.py` tests, and they both fail on boards like PYBD_SFx and RPI_PICO_W due to the deficiency. With the fix here, both of those tests now pass on lwIP targets, along with all existing socket tests. Signed-off-by: Damien George <damien@micropython.org>

This adds support to `mp_raw_code_save_fun_to_bytes()` so that it can handle saving functions that have children. It does this by inspecting the MP_BC_MAKE_FUNCTION/etc opcodes to work out how many children there are, and creating a tree of simplified raw code information. Signed-off-by: Damien George <damien@micropython.org>
If a function has children then the code object returned from __code__ must contain an `mp_raw_code_t` (actually `mp_raw_code_truncated_t` is enough) that points to the child table. Signed-off-by: Damien George <damien@micropython.org>
This commit adds support to the `marshal` module to be able to dump
functions that have child functions. For example:
import marshal
def f():
def child():
return 1
return child
marshal.dumps(f.__code__)
It also covers the case of marshalling functions that use list
comprehensions, because a list comprehension uses a child function.
This is made possible by the newly enhanced
`mp_raw_code_save_fun_to_bytes()` that can now handle nested functions.
Unmarshalling via `marshal.loads()` already supports nested functions
because it uses the standard `mp_raw_code_load_mem()` function which is
used to import mpy files (and hence can handle all possibilities).

This adds support for the ALT11 alternate function mode on MIMXRT1176 MCUs, enabling FLEXPWM channels on GPIO_AD pins that were previously unavailable for PWM use. Changes: - Add PIN_AF_MODE_ALT11 enum to pin.h - Add ALT11 column to MIMXRT1176_af.csv with FLEXPWM mappings - Enables FLEXPWM1-4 on GPIO_AD_06 through GPIO_AD_21 This change only affects MIMXRT1176-based boards (MIMXRT1170_EVK and PHYBOARD_RT1170). Other MIMXRT family chips use alternate function modes ALT0-ALT9 and are not affected. Tested on MIMXRT1176 hardware with PWM output on GPIO_AD_14 (FLEXPWM3_PWM0_X).

Currently the mimxrt port has a resolution of only 1 second for `machine.RTC().datetime()` and `time.time_ns()`. This means (among other things) that it fails the `tests/extmod/time_time_ns.py` test, which requires requires at least 5ms of resolution. The underlying RTC hardware is just a 64-bit counter, and the HAL functions `SNVS_LP_SRTC_GetDatetime()` and `SNVS_LP_SRTC_SetDatetime()` do conversions between y/m/d/h/m/s and this 64-bit value, which counts at a rate of 32kHz. This commit changes the RTC code to access the 64-bit counter directly and therefore improve resolution of all RTC functions to 1/32768 seconds. That makes things much simpler because it a lot of places the code wants to know the number of seconds since the Epoch. Currently it uses a combination of `SNVS_LP_SRTC_GetDatetime()` and `timeutils_seconds_since_epoch()` which converts the 64-bit counter to date-time and then back to seconds. Those operations are computationally expensive. With this commit, getting the number of seconds since the Epoch is as simple as reading the 64-bit counter and dividing by 32768. We can leverage a lot of the timeutils functions to simplify everything, and make it similar to other ports like rp2. Benefits of this change: - simpler, more efficient code to get/set RTC - `machine.RTC().datetime()` now has a non-zero value in the last slot, being the number of microseconds, and has a resolution of 1/32768 seconds - `time.time_ns()` now has a resolution of 1/32768 seconds - the `test/extmod/time_time_ns.py` test now passes Signed-off-by: Damien George <damien@micropython.org>

The test runners have evolved over time and become more and more complex. In particular `tests/run-tests.py` is rather large now. The test runners also duplicate some functionality amongst themselves.
