CRUX PPC 2.7 is on the way!

CRUX PPC 2.7 32bit and 64bit includes glibc 2.12.1, gcc 4.5.1 and binutils 2.20.1

Important changes:
IBM R6K 604e/604ev/604r support removed (we dont' have a machine to test our ISO).

A first test iso is going on the way.

A first CRUX PPC 2.7 test iso is going on the way, at least the ppc/core repository is quite ready.

Code:

glibc-2.12.1+20100817.patch
gcc-4.5.2-20100930
binutils-2.20.51-20101006
libgmp-5.0.1
libmpfr-3.0.0-p4
libmpc-0.8.2
ppl-0.11
cloog-ppl-0.15.10

These trunk toolchain components (gcc and binutils) are needed to fix a static linking (serious) issue on our architecture.

that's a trimmed test iso, anyway this one 'd be able to work on POWER5 and POWER6 too 'cause there is a reworked serial_console script.

you have now enough boot options for pseries:

Welcome to the CRUX PPC 2.7 installer!
Hit <TAB> for boot options.

we are working on our first public 2.7 Release Candidate.

Code:

CRUX PPC 2.7 includes:
glibc 2.12.2
gcc 4.5.2
binutils 2.21
libgmp-5.0.1
libmpfr-3.0.0-p8

It's available our first release candidate for 32bit.
Important changes are about IBM legacy RS6K 604e/604ev/604r. The support is officially removed as we do not have anymore a machine to test our ISO.

if you experience any problems booting, please try adding rootdelay=30,bootdelay=30 to the kernel parameters...
Also note that all the disks are now seen as scsi, so what used to be hda will now be sda, and the cdrom will be sr0.

have fun ;)

RC1 - known issues:

Code:

1) ppc32,ppc64: the handbook isn't yet updated
2) ppc32,ppc64: yaboot's package must be fixed and it could not work properly
3) ppc64: on PPC970 SLOF based machines (Power.org Bimini, YDL Powerstation, IBM Blade JS20/JS21) yaboot's ISO does not see /etc/yaboot.conf [*]
4) ppc32,ppc64: xorg-server isn't yet deeply tested
5) ppc32: Acube Sam460ex support does not yet implemented
6) ppc64: setup could fail, maybe a typo somewhere

a. When you are presented with "Press 's' to enter Open Firmware.", immediately press the [s] key.
b. When you are presented with the firmware ("SLOF" BIOS) prompt, type:

c. When you are presented with the 'yaboot' prompt, type:

2.7 repos - known issues:

Code:

1) opt/yaboot must be fixed
2) opt/yaboot-bin must be fixed
3) opt/icedtea6-bin-ppc* must be rebuilt (but it works with the old CRUX PPC 2.6 package)
4) opt/openoffice-bin-ppc* must be rebuilt (but it works with the old CRUX PPC 2.6 package)
5) xorg/mesa3d segfaults if gallium support is enabled

opt/yaboot is now fixed but there is still a big issue with ofpath that's unable to find devices on Apple's machines using new libata (pata) linux kernel drivers.
You could read it through /proc/device-tree/aliases/ or you can use the reworked script by JoseJX from Gentoo:
http:/ /dev.gentoo.org/~josejx/new-ofpath

The setup script on ppc64 is now fixed.

A new CRUX PPC 2.7 RC2 install iso is on the way for both 32 and 64 bit.
Please stay tuned and give us a feedback!

CRUX PPC 2.7RC2
It's available our second release candidate.

RC2 - known issues:

Code:

1) ppc32,ppc64: the handbook isn't yet updated
2) ppc64: on PPC970 SLOF based machines (Power.org Bimini, YDL Powerstation, IBM Blade JS20/JS21) yaboot's ISO does not see /etc/yaboot.conf [*]
3) ppc64: we noticed some boot problems on ppc64 machines with usb/firewire addons cards thus remove them to install. This issue is fixed only with the new linux-2.6.38-rc3 kernel.
4) ppc32: Acube Sam460ex support it's not implemented. Skipped.
5) ppc32: Genesi Efika bootkernel doesn't work.
6) ppc32,ppc64: yaboot has still a big issue with ofpath command.
7) ppc64: machines with PATA_WINBOND (Symphony Labs SL82c105), like the IBM 9114-275, could read some kernel warning: CDROM (ioctl) error.


[*]
a. When you are presented with "Press 's' to enter Open Firmware.", immediately press the [s] key.
b. When you are presented with the firmware ("SLOF" BIOS) prompt, type:
boot cdrom [ENTER]
c. When you are presented with the 'yaboot' prompt, type:
cdrom:0,/ppc/ppc64/vmlinux root=/dev/sr0  [ENTER]
  or
cdrom:0,/ppc/ppc64/vmlinux root=/dev/sr0 console=ttyS0,19200 [ENTER]

ofpath from yaboot is still unable to find devices on Apple's machines using new libata (pata) linux kernel drivers.
We recommend to read the path devices directly through /proc/device-tree/aliases/ anyway are now present ofpathname (from IBM powerpc-utils) and new-ofpath i.e. the reworked script by JoseJX from Gentoo PPC.
As suggestion you ought to use new-ofpath for Apple machines and ofpathname for IBM machines.

We received this advise[*] about an issue with LVM2 on big endian.

I noticed that 2.02.83 sources were already removed in favour of a fixed 2.02.84.
LVM2 port isn't part of CRUX PPC overlay and it's synced with x86 release thus it will normally updated with the main x86 project .

The bugged release is, instead, present with CRUX PPC 2.7RC in opt/ collection packages therefore be careful if you already used it.

Code:

[*]
Versions 2.02.75 to 2.02.83 inclusive calculated metadata checksums
incorrectly on big endian archs.

2.02.84 corrects this, metadata created with those versions can't be
read on little endian archs or on earlier or later versions.

Workaround for folk affected is to make sure their metadata backups are
up-to-date before upgrading to 2.02.84 then after the upgrade restore
the metadata from backup.
