• toolchain: with binutils-2.23.x, gcc-4.7.x, glibc-2.16.x
  • (e)glibc-2.17: ppc-fsqrt pending patches - http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/eglibc/eglibc-2.17
  • (e)glibc-2.17: 476 optimizations - upstream fix for ppc4x0
  • (e)glibc-2.17: POWER7 optimizations: memchr, wcschr, wcscpy, wcsrchr
  • (e)glibc-2.16: more optimized functions for PowerPC, deprecated RPC headers and functions available at compile time as they were before version 2.14
  • (e)glibc-2.15: PPC optimizations: nearbyint, strcasecmp
  • (e)glibc-2.14.x needs separate rpc headers to be added : The RPC implementation in libc is obsoleted. Old programs keep working but new programs cannot be linked with the routines in libc anymore. Programs in need of RPC functionality must be linked against TI-RPC. The TI-RPC implementation is IPv6 enabled and there are other benefits. Visible changes of this change include (obviously) the inability to link programs using RPC functions without referencing the TI-RPC library and the removal of the RPC headers from the glibc headers.
  • (e)glibc-ports-2.13: 476 optimizations: memcpy, memcmp, memset, strcmp, strncmp, strcpy, strlen - they hang the new ld on 405/4x0
  • (e)glibc-2.13: POWER7 optimizations: memset, memcmp, strncmp
  • gmp-5.x: ABI=mode32 is broken
  • bump graphite support with isl built-in backend (remove cloog-ppl and add cloog)
  • Decimal Floating Point - http://www.ibm.com/developerworks/wikis/display/WikiPtype/Decimal+Floating+Point - but with don't have any modern machine capable to do that!
• kernel
  • bump to 3.x
  • ppc64: scsi/ipr failed to initialize >=linux-3.0.9, >=linux-3.1.1
  • ppc32: issue that prevents to boot on very old G3 and dual G4 machines and qemu too
  • ppc32/ppc64: pata_sl82c105 is unable to properly handle dma (indeed it try to use mwdma2)
  • ppc64: Remove memory DLPAR operation fails on POWER6/POWER7 - http://lists.debian.org/debian-powerpc/2011/12/msg00029.html
  • powerstation: it works only with Open Firmware framebuffer, more test with Radeon KMS are needed
  • powerstation: radeon kms doesn't work with FireGL V5600 (pcie/video)

  • sam460ex: it doesn't create other fb devices (e.g. for a pcie addon video card)
  • sam460ex: it works only with SM501 framebuffer, more test with Radeon KMS are needed
  • sam460ex: kernel panic using a pci addon video card
  • sam460ex: sound - ??gdium - http://www.mail-archive.com//msg00066.html - http://lists.en.qi-hardware.com/pipermail/planet-log-text/2010-April/000550.html - - http://old.nabble.com/Gdium:-dmesg-output-td24748808.html - http://git.opensde.net/users/amery/linux-2.6.29-gdium - http://git.linux-cisco.org/?p=linux-mips.git;a=shortlog;h=refs/heads/linux-gdium
