      [POWERPC] cell: add RAS support · acf7d768
      Benjamin Herrenschmidt authored
      This is a first version of support for the Cell BE "Reliability,
      Availability and Serviceability" features.
      It doesn't yet handle some of the RAS interrupts (the ones described in
      iic_is/iic_irr), I'm still working on a proper way to expose these. They
      are essentially a cascaded controller by themselves (sic !) though I may
      just handle them locally to the iic driver. I need also to sync with
      David Erb on the way he hooked in the performance monitor interrupt.
      So that's all for 2.6.17 and I'll do more work on that with my rework of
      the powerpc interrupt layer that I'm hacking on at the moment.

      powerpc: Unify the 32 and 64 bit idle loops · a0652fc9
      Paul Mackerras authored
      This unifies the 32-bit (ARCH=ppc and ARCH=powerpc) and 64-bit idle
      loops.  It brings over the concept of having a ppc_md.power_save
      function from 32-bit to ARCH=powerpc, which lets us get rid of
      native_idle().  With this we will also be able to simplify the idle
      handling for pSeries and cell.

      [PATCH] powerpc: Fix runlatch performance issues · cb2c9b27
      Anton Blanchard authored
      The runlatch SPR can take a lot of time to write. My original runlatch
      code would set it on every exception entry even though most of the time
      this was not required. It would also continually set it in the idle
      loop, which is an issue on an SMT capable processor.
      Now we cache the runlatch value in a threadinfo bit, and only check for
      it in decrementer and hardware interrupt exceptions as well as the idle
      loop. Boot on POWER3, POWER5 and iseries, and compile tested on pmac32.

      [PATCH] cell: enable pause(0) in cpu_idle · c902be71
      Arnd Bergmann authored
      This patch enables support for pause(0) power management state
      for the Cell Broadband Processor, which is import for power efficient
      operation. The pervasive infrastructure will in the future enable
      us to introduce more functionality specific to the Cell's
      pervasive unit.

      [PATCH] powerpc: merge code values for identifying platforms · 799d6046
      Paul Mackerras authored
      This patch merges platform codes.  systemcfg->platform is no longer used,
      systemcfg use in general is deprecated as much as possible (and renamed
      _systemcfg before it gets completely moved elsewhere in a future patch),
      _machine is now used on ppc64 along as ppc32.  Platform codes aren't gone
      yet but we are getting a step closer. A bunch of asm code in head[_64].S
      is also turned into C code.

      [PATCH] powerpc: Merge cacheflush.h and cache.h · 26ef5c09
      David Gibson authored
      The ppc32 and ppc64 versions of cacheflush.h were almost identical.
      The two versions of cache.h are fairly similar, except for a bunch of
      register definitions in the ppc32 version which probably belong better
      elsewhere.  This patch, therefore, merges both headers.  Notable
      	- there are several functions in cacheflush.h which exist only
      on ppc32 or only on ppc64.  These are handled by #ifdef for now, but
      these should probably be consolidated, along with the actual code
      behind them later.
      	- Confusingly, both ppc32 and ppc64 have a
      flush_dcache_range(), but they're subtly different: it uses dcbf on
      ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which
      uses dcbf.  These too should be merged and consolidated later.
      	- Also flush_dcache_range() was defined in cacheflush.h on
      ppc64, and in cache.h on ppc32.  In the merged version it's in
      	- On ppc32 flush_icache_range() is a normal function from
      misc.S.  On ppc64, it was wrapper, testing a feature bit before
      calling __flush_icache_range() which does the actual flush.  This
      patch takes the ppc64 approach, which amounts to no change on ppc32,
      since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean
      renaming flush_icache_range() to __flush_icache_range() in
      arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S
      	- The PReP register info from asm-ppc/cache.h has moved to
      	- The 8xx register info from asm-ppc/cache.h has moved to a
      new asm-powerpc/reg_8xx.h, included from reg.h
      	- flush_dcache_all() was defined on ppc32 (only), but was
      never called (although it was exported).  Thus this patch removes it
      from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely.  It's
      left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.

      ppc: Various minor compile fixes · fd582ec8
      Paul Mackerras authored
      This fixes up a variety of minor problems in compiling with ARCH=ppc
      arising from using the merged versions of various header files.
      A lot of the changes are just adding #include <asm/machdep.h> to
      files that use ppc_md or smp_ops_t.
      This also arranges for us to use semaphore.c, vecemu.c, vector.S and
      fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

      powerpc: Merge enough to start building in arch/powerpc. · 14cf11af
      Paul Mackerras authored
      This creates the directory structure under arch/powerpc and a bunch
      of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
      arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
      to build a 32-bit powermac kernel with ARCH=powerpc.
      For now we are getting some unmerged files from arch/ppc/kernel and
      arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
      to files in those directories and files outside arch/powerpc.
      The boot directory is still not merged.  That's going to be interesting.

      [PATCH] ppc32: Fix cpufreq problems · 7a648b9e
      Benjamin Herrenschmidt authored
      This patch updates the PowerMac cpufreq driver.  It depends on the addition
      of the suspend() method (my previous patch) and on the new flag I defined
      to silence some warnings that are normal for us.
      It fixes various issues related to cpufreq on pmac, including some crashes
      on some models when sleeping the machine while in low speed, proper voltage
      control on some newer machines, and adds voltage control on 750FX based G3

      Linus Torvalds authored
      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
