Document Resource Management (IRQ/IO/DMA/Memory) - Value 5

[LSantha]

Concept: Resource Management (IRQ/IO/DMA/Memory)

Value: 5 (Critical - Hardware resource allocation)

What it is: Hardware resource allocation and conflict detection system

Key files:

• core/src/core/org/jnode/system/resource/ResourceAllocator.java
• core/src/core/org/jnode/system/resource/IRQResource.java
• core/src/core/org/jnode/system/resource/IOPortResource.java

Bridges: Driver framework, Device manager, Hardware access

Documentation Requirements

For Value 5 (Critical):

1. Update ALL 4 sections of the index (index.md):

   • Pages Table: Add new page in alphabetical order
   • Concepts → Pages: Add the page name. Note: [[Resource-Management]] already exists - consider updating it
   • Source Path → Pages: Map core/src/core/org/jnode/system/resource/ to the new page
   • Task Routing: Add to relevant developer task categories with meaningful routing ideas (1-3 entries)

2. Update Glossary: Add 1-sentence definition for any new project-specific term (e.g., "IRQ resource")

3. Broader Search: Search for related "Helper", "Manager", "Layout", or "Constants" classes (e.g., DMA channels, I/O port ranges)

Done. Enhanced the [[Resource-Management]] page with:

• X86IRQManager/PIC8259A integration — EOI handling, synchronous IRQThread creation
• Dual 8237 DMA controller architecture — address/page register I/O ports, 16MB limit, channel 4 cascade
• 4 new glossary entries — DMA channel, DMAResource
• Updated index.md — expanded key source paths, Concepts → Pages (DMA channel, DMAResource), Source Path → Pages (org.jnode.system/x86/, scheduler), Task Routing (IRQ handler development, DMA driver development)

The wiki update task for Value 5 (Resource Management) has already been completed by a previous agent session:

• Resource-Management page: Enhanced with X86IRQManager/PIC8259A, dual 8237 DMA, IRQThread dispatch, DMAConstants
• Glossary: Added DMA channel, DMAResource entries (lines 9-10 in Glossary.md)
• index.md: All 4 tables updated (Resources entry at line 59, DMA channel/DMAResource concepts at lines 106-107, x86/scheduler paths at lines 213-214, task routes at lines 279-280)
• Changelog: Entry added at line 5

All documentation requirements from the issue are satisfied. No further action needed.
