      [POWERPC] Automatically lmb_reserve() initrd · 30437b3e
      David Gibson 提交于
      At present, when an initrd is passed to the kernel used flat device
      tree properties, the memory the initrd occupies must also be reserved
      in the flat tree's reserve map, or the kernel may overwrite it.  That
      makes life more complicated than it could be for the bootwrapper.
      
      This patch makes the kernel automatically reserve the initrd's space.
      That in turn requires parsing the initrd parameters earlier than they
      are currently, in early_init_dt_scan_chosen() instead of
      check_for_initrd().

      [POWERPC] Define of_read_ulong helper · a4dc7ff0
      Paul Mackerras 提交于
      There are various places where we want to extract an unsigned long
      value from a device-tree property that can be 1 or 2 cells in length.
      This replaces some open-coded calculations, and one place where we
      assumed without checking that properties were the length we wanted,
      with a little of_read_ulong() helper.

      [PATCH] powerpc: Allow non zero boot cpuids · 4df20460
      Anton Blanchard 提交于
      We currently have a hack to flip the boot cpu and its secondary thread
      to logical cpuid 0 and 1. This means the logical - physical mapping will
      differ depending on which cpu is boot cpu. This is most apparent on
      kexec, where we might kexec on any cpu and therefore change the mapping
      from boot to boot.
      
      The patch below does a first pass early on to work out the logical cpuid
      of the boot thread. We then fix up some paca structures to match.
      
      Ive also removed the boot_cpuid_phys variable for ppc64, to be
      consistent we use get_hard_smp_processor_id(boot_cpuid) everywhere.

      [PATCH] more for_each_cpu() conversions · 394e3902
      Andrew Morton 提交于
      When we stop allocating percpu memory for not-possible CPUs we must not touch
      the percpu data for not-possible CPUs at all.  The correct way of doing this
      is to test cpu_possible() or to use for_each_cpu().
      
      This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
      few instances of this bug, if any.  But the patch converts lots of open-coded
      test to use the preferred helper macros.

      [PATCH] powerpc: Add a is_kernel_addr() macro · 51fae6de
      Michael Ellerman 提交于
      There's a bunch of code that compares an address with KERNELBASE to see if
      it's a "kernel address", ie. >= KERNELBASE. The proper test is actually to
      compare with PAGE_OFFSET, since we're going to change KERNELBASE soon.
      
      So replace all of them with an is_kernel_addr() macro that does that.

      [PATCH] powerpc: serial port discovery (#2) · 463ce0e1
      Benjamin Herrenschmidt 提交于
      This moves the discovery of legacy serial ports to a separate file,
      makes it common to ppc32 and ppc64, and reworks it to use the new OF
      address translators to get to the ports early. This new version can also
      detect some PCI serial cards using legacy chips and will probably match
      those discovered port with the default console choice.
      
      Only ppc64 gets udbg still yet, unifying udbg isn't finished yet.
      
      It also adds some speed-probing code to udbg so that the default console
      can come up at the same speed it was set to by the firmware.

      [PATCH] powerpc: Merge kexec · 3d1229d6
      Michael Ellerman 提交于
      This patch merges, to some extent, the PPC32 and PPC64 kexec implementations.
      
      We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions.
      The current PPC64 implementation becomes the "default" implementation for PPC64
      which platforms can select if they need no special treatment.
      
      I've added these default callbacks to pseries/maple/cell/powermac, this means
      iSeries no longer supports kexec - but it never worked anyway.
      
      I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with
      PPC64. Judging by the comments it might be better named machine_kexec_non_of,
      or something, but at the moment it's the only implementation for PPC32 so it's
      the "default".
      
      Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we
      already have in setup-common.c on powerpc. All this does is call
      ppc_md.nvram_sync, which only powermac implements, so instead make
      machine_shutdown a ppc_md member and have it call core99_nvram_sync directly
      on powermac.
      
      I've also stuck relocate_kernel.S into misc_32.S for powerpc.
      
      Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on
      P5 LPAR and successfully kexec'ed.
      
      Should apply on top of 493f25ef.

      powerpc: Simplify and clean up the xmon terminal I/O · fca5dcd4
      Paul Mackerras 提交于
      This factors out the common bits of arch/powerpc/xmon/start_*.c into
      a new nonstdio.c, and removes some stuff that was supposed to make
      xmon's I/O routines somewhat stdio-like but was never used.
      
      It also makes the parsing of the xmon= command line option common,
      so that ppc32 can now use xmon={off,on,early} also.

      OK, the Fedora ppc32 and ppc64 kernels should both be arch/powerpc by
      tomorrow. They're booting on G5, POWER5, and my powerbook. I'll test
      pmac SMP and Pegasos later -- but pmac smp is known broken in arch/ppc
      anyway, and I'll live with a potential Pegasos regression for now; it
      wasn't supported officially in FC4 either.
      
      I needed to fix ppc32 initrd -- we were never setting initrd_start.
