* [POWERPC] cell: add shadow registers for pmd_regKevin Corry2006-10-252-0/+52
| | | | | | | | | | | | | Many of the registers in the performance monitoring unit are write-only. We need to save a "shadow" copy when we write to those registers so we can retrieve the values if we need them later. The new cbe_pmd_shadow_regs structure is added to the cbe_regs_map structure so we have the appropriate per-node copies of these shadow values.

* [POWERPC] spufs: Add isolated-mode SPE recycling supportJeremy Kerr2006-10-254-8/+81
| | | | | | | | | | | | | | | | | | | When in isolated mode, SPEs have access to an area of persistent storage, which is per-SPE. In order for isolated-mode apps to communicate arbitrary data through this storage, we need to ensure that isolated physical SPEs can be reused for subsequent applications. Add a file ("recycle") in a spethread dir to enable isolated-mode recycling. By writing to this file, the kernel will reload the isolated-mode loader kernel, allowing a new app to be run on the same physical SPE. This requires the spu_acquire_exclusive function to enforce exclusive access to the SPE while the loader is initialised.

* [POWERPC] spufs: allow isolated mode apps by starting the SPE loaderarnd@arndb.de2006-10-253-16/+148
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds general support for isolated mode SPE apps. Isolated apps are started indirectly, by a dedicated loader "kernel". This patch starts the loader when spe_create is invoked with the ISOLATE flag. We do this at spe_create time to allow libspe to pass the isolated app in before calling spe_run. The loader is read from the device tree, at the location "/spu-isolation/loader". If the loader is not present, an attempt to start an isolated SPE binary will fail with -ENODEV. Update: loader needs to be correctly aligned - copy to a kmalloced buf. Update: remove workaround for systemsim/spurom 'L-bit' bug, which has been fixed. Update: don't write to runcntl on spu_run_init: SPU is already running. Update: do spu_setup_isolated earlier Tested on systemsim.

* [POWERPC] spufs: wrap mfc sdr accessMasato Noguchi2006-10-255-11/+7
| | | | | | | | | | | | | | | | | | | SPRN_SDR1 and the SPE's MFC SDR are hypervisor resources and are not accessible from a logical partition. This change adds an access wrapper. When running on bare H/W, the spufs needs to only set the SPE's MFC SDR to the value of the PPE's SPRN_SDR1 once at SPE initialization, so this change renames mfc_sdr_set() to mfc_sdr_setup() and moves the access of SPRN_SDR1 into the mmio wrapper. It also removes the now unneeded member mfc_sdr_RW from struct spu_priv1_collapsed.

* [POWERPC] Move iSeries initrd logic into device treeMichael Ellerman2006-10-242-34/+13
| | | | | | | | | | | | | | Remove the iSeries initrd logic, instead just store the initrd location and size in the device tree so generic code can do the rest for us. The iSeries code had a "feature" which the generic code lacks, ie. if the compressed initrd is bigger than the configured ram disk size, we make the ram disk size bigger. That's bogus, as the compressed size of the initrd tells us nothing about how big the ram disk needs to be. If the ram disk isn't big enough you just need to make CONFIG_BLK_DEV_RAM_SIZE larger.

* [POWERPC] Make sure interrupt enable gets restored properlyPaul Mackerras2006-10-182-9/+23
| | | | | | | | | | | | | The lazy IRQ disable patch missed a couple of places where the interrupt enable flags need to be restored correctly. First, we weren't restoring the paca->hard_enabled flag on interrupt exit. Instead of saving it on entry, we compute it from the MSR_EE bit in the MSR we are restoring at exit. Secondly, the MMU hash miss code was clearing both paca->soft_enabled and paca->hard_enabled but not restoring them in the case where hash_page was able to resolve the miss from the Linux page tables.

* [POWERPC] Lazy interrupt disabling for 64-bit machinesPaul Mackerras2006-10-1612-111/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements a lazy strategy for disabling interrupts. This means that local_irq_disable() et al. just clear the 'interrupts are enabled' flag in the paca. If an interrupt comes along, the interrupt entry code notices that interrupts are supposed to be disabled, and clears the EE bit in SRR1, clears the 'interrupts are hard-enabled' flag in the paca, and returns. This means that interrupts only actually get disabled in the processor when an interrupt comes along. When interrupts are enabled by local_irq_enable() et al., the code sets the interrupts-enabled flag in the paca, and then checks whether interrupts got hard-disabled. If so, it also sets the EE bit in the MSR to hard-enable the interrupts. This has the potential to improve performance, and also makes it easier to make a kernel that can boot on iSeries and on other 64-bit machines, since this lazy-disable strategy is very similar to the soft-disable strategy that iSeries already uses. This version renames paca->proc_enabled to paca->soft_enabled, and changes a couple of soft-disables in the kexec code to hard-disables, which should fix the crash that Michael Ellerman saw. This doesn't yet use a reserved CR field for the soft_enabled and hard_enabled flags. This applies on top of Stephen Rothwell's patches to make it possible to build a combined iSeries/other kernel.

We were bitten by this when we made an x86_64 platform whose BIOS provides an Interrupt Source Override for the SCI itself. Apparently the override has no effect for the System Control Interrupt, and this appears to be because of the way the SCI is setup in the ACPI code. It does not handle the case where busirq != gsi. The code that sets up the SCI routing assumes that bus irq == global irq. So there is simply no provision for telling it otherwise. The attached patch provides this mechanism. This patch provided by David Bulkow, was tested on an i386 platform, which does not use the SCI override, and also on an x86_64 platform which does use an override.
