Talk:Linux 3 on PS3

Firstly, thanks for coming (and contributing) to PS3DevWiki. It seems like "official" now. :)

I don't know if you notice but EussNL made a backup of your repository in http://www.ps3devwiki.com/files/OtherOSplusplus/ ; but it's not "up to date". So if you want/can merge your latest changes (from gitbrew.org/~glevand/ps3/ but you told me you got it on your hdd) to this "new" repository, it would be awesome.

Thanks a lot.

Contact defyboy or me (eussNL) if you need anything more :)

Changes from 2.6 to 3.x

OtherOS++ page is freezed about linux howtos, deep changes has been done in the last year.
If you plan to switch on Linux 3 thare are many things you need to know!

SS_patch_CFW is NOT needed to gain full access to SS, even dispmgr_access.sh script!
All is done by new kernel drivers and userland tools: ps3vuart-tools replaces old ps3dm-tools.

/dev/ps3flash device:
Graf's drivers has been rewritten, no more /dev/vflash*
File /etc/udev/rules.d/70-persistent-ps3flash.rules must be changed as:
NAND:	KERNEL=="ps3flashf", SYMLINK+="ps3flash"
NOR:	KERNEL=="ps3nflashf", SYMLINK+="ps3flash"

Wireless is fully handled by patches:
no more ps3_gelic.disable_eurus_ctrl_iface=1 boot parameter for NAND;
improved ps3_jupiter driver for NOR.

7th SPU:
boot parameter has changed to:
spu_base.enum_shared=1

(New ps3sed and ps3strgmngr should overcome the need of emer_init_patch, letting us resize the GameOS region.)

It seems that with the 3.x kernels there is a bug preventing propper shutdown with usb keyboards atached:

solution is issuing before halting: rmmod usbhid

place in /etc/init.d/halt in the begining of the do_stop() function <- this was tested in debian

PS: man i need to learn wiki syntax... skiski

Don't forget to strip you kernel (petitboot wont boot to it otherwise)

ppu-strip --strip-unneeded /boot/vmlinuz-3.x.x

Kernel 3.6.2 during reboot gives:

Problem with usb keyboard still persists. Even after patching halt script reboot hangs ps3. But if you disconnect keyboard right after script starts reboot works properly.
