* [PATCH] ppc64: Export machine_power_off for therm_pm72 moduleBenjamin Herrenschmidt2005-08-24
| | | | | | | | | | | This patch puts back the export of machine_power_off() that was removed by some janitor as it's used for emergency shutdown by the G5 thermal control driver. Wether that driver should use kernel_power_off() instead is debatable and a post-2.6.13 decision. In the meantime, please commit that patch that fixes the driver for now.

* [PATCH] ppc64: iommu vmerge fixBrian King2005-08-17
| | | | | | | | | | | | This fixes a bug in the PPC64 iommu vmerge code which results in the potential for iommu_unmap_sg to go off unmapping more than it should. This was found on a test system which resulted in PCI bus errors due to PCI memory being unmapped while DMAs were still in progress.

* [PATCH] iSeries build with newer assemblers and compilersStephen Rothwell2005-08-17
| | | | | | | | | | | | | | | | | | Paulus suggested that we put xLparMap in its own .c file so that we can generate a .s file to be included into head.S. This doesn't get around the problem of having it at a fixed address, but it makes it more palatable. It would be good if this could be included in 2.6.13 as it solves our build problems with various versions of binutils and gcc. In particular, it allows us to build an iSeries kernel on Debian unstable using their biarch compiler. This has been built and booted on iSeries and built for pSeries and g5.

* [PATCH] pci and yenta: pcibios_bus_to_resourceDominik Brodowski2005-08-05
| | | | | | | | | | | | | | | In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

* [PATCH] Xmon bug fix for soft-resetHaren Myneni2005-08-03
| | | | | | | | | | | | | | | | | | For soft reset during system hang, got an error "CPU did not take control" for some CPUs even though they responded to soft-reset (called SystemReset, die and called debugger - xmon). First these CPUs entered into xmon by IPI callback and then got a soft-reset exception and re-entered into xmon again. The first CPU which re-entered into xmon got the output lock and made into xmon successfully without unlocking. Hence, the next CPU(s) which re-entered into xmon try to acquire a lock (get_output_lock). Therefore, we can not view state of those CPU(s).

* [PATCH] ppc64: POWER 4 fails to boot with NUMAMike Kravetz2005-08-02
| | | | | | | | | | | | | | | | | If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is because of special processing needed to handle invalid node IDs (0xffff) on POWER 4. My previous patch to handle memory 'holes' within nodes forgot to add this special case for POWER 4 in one place. In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes much sense. Are there POWER 4 based systems with NUMA characteristics that are presented by the firmware? But, distros want one kernel for all systems so NUMA is on by default in their kernels. The patch handles those cases.

* [PATCH] ppc64: remove another fixed address constraintDavid Gibson2005-07-27
| | | | | | | | | | | | | | | | | | Presently the LparMap, one of the structures the kernel shares with the legacy iSeries hypervisor has a fixed offset address in head.S. This patch changes this so the LparMap is a normally initialized structure, without fixed address. This allows us to use macros to compute some of the values in the structure, which wasn't previously possible because the assembler always uses signed-% which gets the wrong answers for the computations in question. Unfortunately, a gcc bug means that doing this requires another structure (hvReleaseData) to be initialized in asm instead of C, but on the whole the result is cleaner than before.

* [PATCH] ppc64: dynamically allocate segment tablesDavid Gibson2005-07-27
| | | | | | | | | | | | | | | | | | | PPC64 machines before Power4 need a segment table page allocated for each CPU. Currently these are allocated statically in a big array in head.S for all CPUs. The segment tables need to be in the first segment (so do_stab_bolted doesn't take a recursive fault on the stab itself), but other than that there are no constraints which require the stabs for the secondary CPUs to be statically allocated. This patch allocates segment tables dynamically during boot, using lmb_alloc() to ensure they are within the first 256M segment. This reduces the kernel image size by 192k... Tested on RS64 iSeries, POWER3 pSeries, and POWER5.

| * [PATCH] ppc64: Replace custom locking code with a spinlockMichael Ellerman2005-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord which is used for serialising access to the queue. Because it's a word (ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or thereabouts in ItLpQueue.c. The xInUseWord is not shared with they hypervisor, so we can replace it with a spinlock and remove the custom code. There is also another locking mechanism (ItLpQueueInProcess). This is redundant because it's only manipulated while the lock's held. Remove it.

| | | | | | | | | | | | | | | | | | | | | | | | Just formatting cleanups: * rename some "nextLpEvent" variables to just "event" * make code fit in 80 columns * use brackets around if/else * use a temporary to make hvlpevent_clear_valid clearer Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
