Playstation 2 linux kernelloader (ps2dev)

kernelloader is a bootloader for ps2 linux and other ps2 operating systems. the current state is:
- Linux can be started. Graphic, USB, network, hard disc, controller pads and memory cards are working. CD/DVD is working with PS1 CDs and PS2 DVDs. Video DVDs can be read by kernelloader and a patched Linux.
- Sound is only working when using LIBSD.IRX and SDRDRV.IRX from the same game disc. SDRDRV.IRX must have version 2.0 or lower (4.01 is not working).
- A playstation kernel simulation is included. Only some ps2 syscalls are supported. Only single thread and a interrupt handler is supported. SIF RPC is working, so all hardware components should work.
- Writing data to an USB stick with Linux on slim PSTwo may destroy data. The fat PS2 doesn't have this problem. It is recommended to use the Live Linux DVD on slim PSTwo.
Changes:
- Better support for network on slim PSTwo.
- Less USB problems (write access is still broken on slim PSTwo).
- Fixed detection of console type (slim or fat).
- Linux Live DVD is now available.
- Fixed eromdrvloader.irx problems.
- Support for loading files in kernelloader from HTTP server (DNS supports TCP server only, no UDP server).
- Fixed USB problems on slim PSTwo when loading sound modules.
- Fixed problems with new modules (modules with X as first letter in ROM0).
- IRX modules in kernelloader can be reloaded to activate change IP configuration.

Note: Not all network status information is available on slim PSTwo.

Supported hardware/modules by linux 2.4.17 in version 2.1:
Hardware/Module Support Status Comment
Bootloader using PS2LINK Working Path can be changed in kernelloader menu using USB keyboard (only for people who can read program code).
Bootloader using network No support Modules not loaded.
Bootloader using USB Working Can be selected from kernelloader menu.
Bootloader using HDD No support Modules not loaded.
Bootloader using MC Working Can be selected from kernelloader menu.
Bootloader using CD/DVD Working Can be selected from kernelloader menu. Burned video DVDs are also readable.
GS Working Code doesn't exist and is not needed. Linux has own graphic driver. Code is required for NetBSD. When using HDTV, you get a pink screen. The SBIOS from RTE doesn't have this problem, but it doesn't support reading from CD/DVDs.
SIFDMA Working SB_SIFDMASTAT is incomplete.
SIFCMD Working Code is complete.
SIFRPC Working Code is incomplete.
IOPHEAP Working Code is complete.
PAD Working SB_PAD_INFOCOMB is missing.
IOP debug output must stay disabled in kernelloader menu.
SOUND Error Sound modules libsd.irx and sdrdrv.irx can be used. The modules from RTE can be used or from game discs. sdrdrv.irx must have version 2.0 or lower.
MC Working SBR_MC_CALL is missing.
CDVD Working Code is incomplete.
PS1 CDs and PS2 DVDs are working. Audio CDs are not tested. Video DVDs are working. New Linux kernel is needed (vmlinux_fat_and_slim_v4.gz).
REMOCON Error Code is missing. Module can be loaded.
USB Working USB keyboard and memory stick tested. Working with slim PSTwo when Linux kernel is patched and rpc interrupt module is loaded. USB write access is failing on heavy load and when using slim PSTwo. Data may be corrupted on slim PSTwo.
HDD Working Working in PIO mode.
The slim PSTwo doesn't have a connector for the HDD, but some models can be extended. There is no support for this hardware configuration. Linux driver need to be rewritten.
INTRELAY.IRX Working ps2link must be disabled to get network interrupts working. The slim PSTwo needs the RPC version.
DMARELAY.IRX Not Working Code is complete, but I am not sure if it is correct. ps2link must be disabled.
SMAP seems not to be used, because linux driver uses newer unknown RPC interface.
USB Keyboard Working Also supported within kernelloader menu.
Network Working with SCPH-10350
and SCPH-10281		 Working in PIO mode.
ps2link must be disabled.
DMA is not working, because linux 2.4.17 driver uses different RPC interface.
The slim ps2dev needs the smaprpc.irx and the ps2dev9.irx modules.
vmlinux_fat_and_slim_v1.gz or higher is the recommended Linux kernel.
New ROM Modules Working See other entries in this table. Only some calls are missing.
Old ROM Modules Working See other entries in this table. Only some calls are missing.
