For me, this (in relation to the prebuild toolchain) sounds like a good reason for a new livecd build.

Since you did not cite what stage you were working with, I cannot respond with complete confidence. I fixed the s/default/defaults thing a while back. Are you seeing this with a current stage, something with a Dec 2007 date? Many of the mirrors have stopped mirroring experimental release materials but have not taken the mirrored content off. So there is a fair amount of old media and stages floating around out there.

The auto/audo bit is something catalyst did/does. I'll look into it. Same with the -J suggestion, although I really thought catalyst did pass the -J.

On http://overlays.gentoo.org/proj/cell/wiki/InstallGentooOnPS3, there is a small typo in the fstab config.

the line:
none /spu spufs default 0 0
should be changed to:
none /spu spufs defaults 0 0

otherwise any program trying to load SPU code will give an error like:
spu_create() Invalid argument

In the stage4 tarball, the fstab has the correct spufs entry, but has a type in one of the "auto" columns where it says "audo".

Thirdly, the LiveCD should be created with the -J flag (Joliet) for mkisofs, as that will enable the PS3 to correctly read otheros.bld from the CD, if it is placed in PS3/otheros/otheros.bld.

I'm not sure who maintains these packages, but there is no feedback form in the wiki page.

Hey Ranger,

I noticed that the mirrors currently contain no disk images and still contain the old stage 4 tarballs under experimental/ppc64. Any idea when those should be back up?

Thanks,
Kyle

We're still a little ways from officially supporting PS3 as a ppc64 platform. I get this question a fair amount so it's worth responding to. The inhibiting factors right now are:

- PS3 required ebuilds were just moved from the cell over to portage and are still ~
- Mainline does not fully support everything we need/want for PS3. We're hoping for 2.6.25. For the record, we also hoped 2.6.23 and 2.6.24.
- Without Gcc-4.3, we lack the cell optimizations for mcpu and mtune. Right now we pass 970 and altivec. This goes in-line with the comment I made in my earlier post about inching towards a profile.

Cool!

Though as always, keep in touch with the docs team and let us know the moment it becomes an officially supported arch, whether on its own or wrapped into ppc/ppc64. That way we can get some stuff into the handbooks.

The more officially-supported Gentoo systems, the merrier! :)

Hello, I have my PS3 with Gentoo now :D and I want to optimize CFLAGS to install other things like Gnome.Should I replace mcpu=cell or do I leave mcpu=970? on:
http://gentoo-wiki.com/Safe_Cflags#Cell_Broadband_Engine_.28Playstation_3.29
the recommendation is cell.

Thank you for your help! Best regards.

Hey Brent we just received our power6 boxes a couple weeks ago. Myself and one of our Unix admins are interested in installing a Linux LPAR for testing before these systems go into production. Id rather not use SUSE and am partial to gentoo anyways which is how I stumbled on this thread. I could offer some feedback on the 2007.0 profile and try and work out the build errors albeit with the limited knowledge that I possess when it comes to debugging code.

hi brent.

just a passing thought as you bring up
the flags.

i was rereading http://forum.beyond3d.com/showthread.php?s=7c9350bc2751cdda0bb5aee91b329bf7&p=893620#post893620 again and remembered about
using -funroll-loops to increase speed.

also, while i assume noones yet
replaced any core PPC linux code with
Altivec routines?, perhaps its time
to see if some optimisations can be found.

it seems such a waste to have the
Altivec chip sat there (almost) idle
taking up power and not being used in
any of the current core OS code.

markos's freevec still seems unused
anywere obvious in any part of the PPC OS codebase, and yet freevec is full of
tested code that works for most app
speed options....

he implyed it could be used to replace
or supliment lots of core code and get
a massive speed boost, such a shame
noone seems to have tryed to run tests
to see if it can boost the PS3 effort.


for readers, that thread was good for test code
code and otpimisations to try.
-----------------

-O0: some basic and minimum optimization
-O2: strong, low-level optimization that benefits most programs
-O3: intense, low-level optimization analysis with basic loop optimization

--------------

i think gcc4 still has broken -03 and still produces slower code than the old ones, but i may be wrong or was it just 4.0.3

In my humble opinion, optimized can be a result of several different things. I would not consider -0-anything the only way to optimize. The passing of the 970 flags was what my original announcement was referring to. Prior to then, as I mentioned in the post, the CFLAGS were not getting set properly in the various stages as they were built, specifically in stage3.

Just for reference, we're working to become more gcc-4.3 savy so that we can actually begin to pass the "cell" mcpu for increased optimization. My hope is that will make things a little more interesting.

Hi there,

Is -O2 really optimal for the PS3? I have little experience of optimising CFLAGS but considering the PS3 doesn't have so much RAM, might -Os be better? Do you know if anyone has done any tests?

Stroller.

keep up the good work. you need to advertise your blog more. does your livecd support the sixaxis controller natively? i wish there were a distro with sixaxis support.

another problem i see is that the otherOS bootloader doesnt drop you backt to gameOS, when there is a bluray game in the tray. id like to be able to use gameOS and otherOS without having to either reset my ps3 or use commands in terminal...

Hi .. I was just wondering if this live CD comes with mplayer or something similar. I would like to play movies through the PS3

Thanks

Terry

The easiest way to do this would be as follows:

- at the kboot prompt, drop to the shell with 'sh'
- at the shell, type 'e2label /dev/sda1 ""' this assumes that sda1 is your rootfs. i dont know what yellow dog does for sure there.
- then type 'reboot' and have the livecd in the drive.

I already installed yellowdog linux on
ps3, I want to boot the livecd-ps3only-xfce4-beta from the ps3 blur rom, but ps3
always boot from the HD ydl, pls give
some advice, thks!

I could include the source but the compiler is removed on the livecd if I remember correctly. if you knew the driver you were interested in, I could consider adding them.

Would it be possible to include the kernel source on the livecd so we can try and compile drivers for e.g. USB Wifi devices and what not ? :)

Thanks for the latest release Brent. I have Gentoo stage 4 installed now on my PS3 and built it from the kernel up. See www.ps3hax.com, there is a forum board for Gentoo on the PS3. Please visit and present your expertise, I am sure it would be most welcome.

Hi there,

Thanks for the tutorial and stage 4 release. It has helped a lot, and been a time saver.

I could not find any of the 2.6.16 kernel src in the stage 4? I was wondering if the kernel src and config could be made available? I'd like to change an option and recompile the kernel on my PS3.

Thanks in advance,
Shane Metler

How is audio currently configured on this release? Is it configured correctly for ALSA? It seems, I can't get anything to work unless I am running OSS emulation...

I am also seeing some error during start up

fsck.ext1 on /dev/sda1

it seems fsck.ext1 is not found on the system. How do I remedy this?
