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.
- Support for DTV (without former pink screen problems).
- Support for VGA.
- Linux 2.4 has the best support. Linux 2.6 is basically working, but not really usable (Only graphic and USB working, no HDD, no other hardware).
Changes:
- Add support for 64 bit kernels.
- Add support for Linux 2.6 initial RAM disk parameters (initrd)
- Fix alignment in SIF command interrupt handler. This could randomly freeze drivers. Which could freeze the whole system. Kernelloader should now support more kernels like the NetBSD kernel.

Supported hardware/modules by linux 2.4.17 in version 2.4:

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	HTTP	Kernel and initrd can be loaded over network, e.g: http://192.168.0.1/vmlinux.gz
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 uses PS2 BIOS or included SBIOS code if not available. VGA need to be selected in kernelloader to use NetBSD. The pink screen screen problem with HDTV is fixed. DTV and VGA is working.
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.
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. Not all models are working.
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.
