| * 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.)

The 3rd and 4th cells are needed to define additional types of interrupt source outside the "normal" external and internal interrupts in FSL SoCs. Define error interrupt, IPIs, and PIC timer sources.

* | powerpc/85xx: Workaroudn e500 CPU erratum A005Liu Yu2011-03-152-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This erratum can occur if a single-precision floating-point, double-precision floating-point or vector floating-point instruction on a mispredicted branch path signals one of the floating-point data interrupts which are enabled by the SPEFSCR (FINVE, FDBZE, FUNFE or FOVFE bits). 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/85xx: Fix writing to spin table 'cpu-release-addr' on ppc64eKumar Gala2011-03-151-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the spin table is located in the linear mapping (which can happen if we have 4G or more of memory) we need to access the spin table via a cacheable coherent mapping like we do on ppc32 (and do explicit cache flush).

* | 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.
