Kernel Project

The non-distribution specific Deos Kernel project.

Description

This is a placeholder for the work performed across multiple kernel experimental and verification baselines. I.e., roadmap sorts of topics.

Distribution   Branch
 Elbert        No current branch in SCM
 FourPeaks     mainline
 G (ARM)       experimental
 multi-core    multi-core

Perhaps this would be better handled as a "product" page like we did on the legacy wiki.

These are the current Kernel projects in work:

Elbert (AKA 7.10)

• 36-bit Support (Deos RAM and FLASH still limited to 32-bit).
• Part of Sybil
• Thread aware debugging. (needed by torta)

Fourpeaks

• Release end of Oct 2014
• ARINC 653 (Chino)
• The remaining part of Sybil not done in 7.10.x
• Deos_MIPS_Port
• Complete Sybil (desired by Malabi)
  • No password in setKernelAttributes (ie FTP)
• MIPS
  • MIPS fast packet.
• Memory Pools
• Deos Cache Partitioning
  • L3 support (ranges)
• POSIX_Access_Controls
• Increase limit on number of kernel files
• E500 (V1?), V2, and MC
  • V1/V2 FPU (SPE) support is kernel only, not math, ansi, or 653.
• read/writePhysicalMemory
• Removed Features
  • Nested mutexes
  • testPageTables and testPageTablesEx

G Distribution

• Deos_ARM_Port

Multicore (on legacy wiki)

• Multicore reference platform
• Remove LLKMI

Roadmap

These are the substantive changes that have been proposed for the kernel that are not yet in a project.

• Are there changes made by Honeywell that need to be brought forward?
• POSIX
• FACE_Project
• Multi-core ARINC 653
• Support for Ada (unsure if there are any kernel changes required).
• More than 32-bit Deos RAM and FLASH
• Make HAL a separately loaded .so (to speed processor porting).
