Porting of Linux 2.6 to PS2

[danielb]

Anyone tried already firewire?
I saw the news about PS2ESDL and it released the source code for firewire...
isn't firewire quiker than usb?

[Xtremegamer]

sure it is but what beats ethernet ?
i was so close at booting linux over my network tho i dont even need it i just want it to work .
just cant figure out the "images" of blackrhino and such also posted an topic about this if anyone elaborate on this please do

@Mega Man: Is the DMA-Support entirely linux-kernel-related, or also dependnt on support delivered by the RTE?

Btw.: I'm going to hit up another news-post about the new SMAP-Drivers and the test-hdl-dump-versions. Tomorrow,...

Same about the Bochs-Port and others deserve it as well,...

[Mega Man]

DMA is implemented in the following components:
- old protocol, dmarelay.irx from RTE Sony's Linux Toolkit DVD 1
- old protocol, dmarelay.irx from kernelloader/TGE
- old protocol, Linux 2.2 IDE driver from Sony's Linux Toolkit DVD 2
- old protocol, Linux 2.2 SMAP driver from Sony's Linux Toolkit DVD 2
- new protocol, dmarelay.irx from RTE from Sony BB Navigator
- new protocol, Linux 2.4.17 IDE driver from Sony BB Navigator
- new protocol, Linux 2.4.17 SMAP driver from Sony BB Navigator
Linux 2.6 has no support for DMA (IDE or SMAP).

The old protocol uses different RPC ids. dmarelay.irx and Linux need to use the same protocol version, otherwise DMA will not be used and everything is slower. The dmarelay.irx from kernelloader/TGE has bug, so it is not working. SP163 used the dmarelay.irx as example for the new code and fixed problems which occured while testing homebrew software (non Linux). I received a fix for dmarelay.irx from SP163. I didn't tested this yet. If this works, it will work with Linux 2.2, but not with Linux 2.4 or 2.6 because of the protocol version.

tell me your results with bochs on your ps2 after you do it, i wasnt able to test it

[danielb]

stupid question...
what bochs do?

[GENERiCpl]

Bochs is a x86(and x86-64 too) emulator.

I'm testing linux 2.6 using nfs.
Apt-get update OK
apt.get install apache 2 ... downloading ERROR:Can not write log, openpty() failed (/dev/pts not mounted?) continued install... done
apt-get install php5 .... downloading

What's this? I'm not using the usb drive at thsi moment...


I cant get to setup a swap file...
i always get "swapfile has holes"

Workaround. Create dummy file. loop device.creat swap there.

PS:How i can make the text use all the screen? e get back borders a little big. using component cable

Its working perfect. Apache+PHP+mysql is way to much for it, too slow.
Megaman, with the future improvements in the instructions it will be faster?

apt.get install apache 2 ... downloading ERROR:Can not write log, openpty() failed (/dev/pts not mounted?) continued install... done

I assume the download error is just a normal random network error. Maybe the openpty message is caused by kernel configuration: CONFIG_LEGACY_PTY_COUNT=0.

What's this? I'm not using the usb drive at thsi moment...

Maybe it is your USB keyboard. In the past the messages apeared in an infinite loop when USB interrupts are not working. Maybe some interrupts were lost, because of high system load.

i always get "swapfile has holes"

I never tried this with Linux, maybe this is normal. NFS seems to have a bug and consumes all memory until out of memory killer can't kill anything anymore. A swap partition also doesn't help. The error happens normally just after installing some few packages. You can see it coming with slabtop.

Theoretically setcrtmode should still work, but I think it need to be compiled with the new toolchain.
SourceForge.net Repository - [kernelloader] Index of /BlackRhino/src/p/ps2utils

Its working perfect. Apache+PHP+mysql is way to much for it, too slow.

I think it will be faster if everything is compiled for EE, but maybe the difference is not recognisable. I recommend to use the internal hard disc, this will improve speed really.

[danielb]

Thanks for you answers.
NFS seems to be working good.
Is x11 already working?

"ERROR:Can not write log, openpty() failed (/dev/pts not mounted?) " appears in every installation.
"/dev/pts" doesn't exists! Should I create it?
