Commit: 092ca5bd61da6344f3b249754b337f2d48dfe08d [POWERPC] Revert chrp_pci_fixup_vt8231_ata devinit to fix libata on pegasos Commit 6d98bda79bea0e1be26c0767d0e9923ad3b72f2e changed the init order for chrp_pci_fixup_vt8231_ata(). It can not work anymore because either the irq is not yet set to 14 or pci_get_device() returns nothing. At least the printk() in chrp_pci_fixup_vt8231_ata() does not trigger anymore. pata_via works again on Pegasos with the change below.

2008-02-25Disable G5 NAP mode during SMU commands on U3Benjamin Herrenschmidt
patch 592a607bbc053bc6f614a0e619326009f4b3829e in mainline. It appears that with the U3 northbridge, if the processor is in NAP mode the whole time while waiting for an SMU command to complete, then the SMU will fail. It could be related to the weird backward mechanism the SMU uses to get to system memory via i2c to the northbridge that doesn't operate properly when the said bridge is in napping along with the CPU. That is on U3 at least, U4 doesn't seem to be affected. This didn't show before NO_HZ as the timer wakeup was enough to make it work it seems, but that is no longer the case. This fixes it by disabling NAP mode on those machines while an SMU command is in flight.

2008-01-15[POWERPC] Fix boot failure on POWER6Paul Mackerras
Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.

2008-01-15[POWERPC] Workaround for iommu page alignmentBenjamin Herrenschmidt
Commit 5d2efba64b231a1733c4048d1708d77e07f26426 changed our iommu code so that it always uses an iommu page size of 4kB. That means with our current code, drivers may do a dma_map_sg() of a 64kB page and obtain a dma_addr_t that is only 4k aligned. This works fine in most cases except for some infiniband HW it seems, where they tell the HW about the page size and it ignores the low bits of the DMA address. This works around it by making our IOMMU code enforce a PAGE_SIZE alignment for mappings of objects that are page aligned in the first place and whose size is larger or equal to a page.

2008-01-11[POWERPC] Fix CPU hotplug when using the SLB shadow bufferMichael Neuling
Before we register the SLB shadow buffer, we need to invalidate the entries in the buffer, otherwise we can end up stale entries from when we previously offlined the CPU. This does this invalidate as well as unregistering the buffer with PHYP before we offline the cpu. Tested and fixes crashes seen on 970MP (thanks to tonyb) and POWER5.

Commit aed3a8c9bb1a8623a618232087c5ff62718e3b9a introduced a definition of notify_spus_active in .../cell/spu_syscalls.c, and another definition under #ifndef MODULE in .../cell/spufs/sched.c. The latter is not necessary and causes the build to fail when CONFIG_SPU_FS=y, so this removes it. It also removes the export of do_notify_spus_active, which is unnecessary.

2007-12-14[POWERPC] Make PS3_SYS_MANAGER default y, not mMichael Ellerman
Currently it's impossible to build a ps3_defconfig which will reboot without modules installed. This makes it all too easy to find yourself with a PS3 that won't reboot. This is because the system manager driver, which provides the reboot mechanism, is only selectable if PS3_ADVANCED is set, else it defaults to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system manager is built as a module. It would be desirable IMHO for the defconfig to produce a kernel that boots and reboots, without needing modules to be installed.

2007-12-13[POWERPC] Fix rounding bug in emulation for double float operatingLiu Yu
This patch fixes rounding bug in emulation for double float operating on PowerPC platform. When pack double float operand, it need to truncate the tail due to the limited precision. If the truncated part is not zero, the last bit of work bit (totally 3 bits) need to '|' 1. This patch is completed in _FP_FRAC_SRS_2(X,N,sz) (arch/powerpc/math-emu/op-2.h). Originally the code leftwards rotates the operand to just keep the truncated part, then check whether it is zero. However, the number it rotates is not correct when N is not smaller than _FP_W_TYPE_SIZE, and it will cause the work bit '|' 1 in the improper case. This patch fixes this issue.

Printk was observed to hang during module unload due to a limited window of characters that may be sent to the hypervisor. The window only reexpands when we receive an ack from the HV and the spinlock here prevents us from ever processing that ack.

PowerMac and CHRP/BriQ platforms have quirks to switch some IDE controllers from legacy mode to fully native mode. Those quirks however will not work properly anymore due to a change to the generic code to better handle legacy IDE resources.

The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (sched: restore deterministic CPU accounting on powerpc), unconditionally calls update_process_tick() in system context. In the deterministic accounting case this is the correct thing to do. However, in the non-deterministic accounting case we need to not do this, since doing this results in the time accounted as hardware irq time being artificially elevated. Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING' checks in time.h into one for neatness.

This reverts commit a2b51812a4dc5db09ab4d4638d4d8ed456e2457e.

2007-11-29Fix boot problem with iSeries lacking hugepage supportMel Gorman
Ordinarily the size of a pageblock is determined at compile-time based on the hugepage size. On PPC64, the hugepage size is determined at runtime based on what is supported by the machine. With legacy machines such as iSeries that do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order being set to -PAGE_SHIFT and a crash results shortly afterwards. This patch adds a function to select a sensible value for pageblock order by default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT is a sensible value before using the hugepage size; if it is not MAX_ORDER-1 is used. This is a fix for 2.6.24. Credit goes to Stephen Rothwell for identifying the bug and testing candidate patches. Additional credit goes to Andy Whitcroft for spotting a problem with respects to IA-64 before releasing. Additional credit to David Gibson for testing with the libhugetlbfs test suite.

The rtas_os_term() routine was being called at the wrong time. The actual rtas call "os-term" will not ever return, and so calling it from the panic notifier is too early. Instead, call it from the machine_reset() call. This splits the rtas_os_term() routine into two: one part to capture the kernel panic message, invoked during the panic notifier, and another part that is invoked during machine_reset(). Prior to this patch, the os-term call was never being made, because panic_timeout was always non-zero. Calling os-term helps keep the hypervisor happy!
