| * perf, powerpc: Handle events that raise an exception without overflowingAnton Blanchard2011-03-162-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Events on POWER7 can roll back if a speculative event doesn't eventually complete. Unfortunately in some rare cases they will raise a performance monitor exception. We need to catch this to ensure we reset the PMC. In all cases the PMC will be 256 or less cycles from overflow.

| | * | powerpc/476: Workaround for PLB6 hangDave Kleikamp2011-02-021-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 476FP core may hang if an instruction fetch happens during an msync following a tlbsync. This workaround makes sure that enough instruction cache lines are pre-fetched before executing the msync. (sync and msync are the same to the compiler.)

This interrupt must be recorded in a one-cycle window when the misprediction is resolved. If this extremely rare event should occur, the result could be: The SPE Data Exception from the mispredicted path may be reported erroneously if a single-precision floating-point, double-precision floating-point or vector floating-point instruction is the second instruction on the correct branch path. According to errata description, some efp instructions which are not supposed to trigger SPE exceptions can trigger the exceptions in this case. However, as we haven't emulated these instructions here, a signal will send to userspace, and userspace application would exit. This patch re-issue the efp instruction that we haven't emulated, so that hardware can properly execute it again if this case happen.

| * | | powerpc/pseries: Disable MSI using new interface if possibleNishanth Aravamudan2011-03-111-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On upcoming hardware, we have a PCI adapter with two functions, one of which uses MSI and the other uses MSI-X. This adapter, when MSI is disabled using the "old" firmware interface (RTAS_CHANGE_FN), still signals an MSI-X interrupt and triggers an EEH. We are working with the vendor to ensure that the hardware is not at fault, but if we use the "new" interface (RTAS_CHANGE_MSI_FN) to disable MSI, we also automatically disable MSI-X and the adapter does not appear to signal any stray MSI-X interrupt.

| * | | powerpc/pseries: Add support for dynamic dma windowsNishanth Aravamudan2011-03-041-0/+587
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If firmware allows us to map all of a partition's memory for DMA on a particular bridge, create a 1:1 mapping of that memory. Add hooks for dealing with hotplug events. Dynamic DMA windows can use larger than the default page size, and we use the largest one possible.
