* KVM: PPC: Find HTAB ourselvesAlexander Graf2010-05-171-5/+0Star
| | | | | | | | | | | | | For KVM we need to find the location of the HTAB. We can either rely on internal data structures of the kernel or ask the hardware. Ben issued complaints about the internal data structure method, so let's switch it to our own inquiry of the HTAB. Now we're fully independend :-).

| | | | | | | | | | | Our shadow MMU code needs to know where the HTAB is located and how big it is. So we need some variables from the kernel exported to module space if KVM is built as a module.

* KVM: PPC: Don't export Book3S symbols on BookEAlexander Graf2010-05-171-0/+2
| | | | | | | | | | Book3S knows how to convert floats to doubles and vice versa. BookE doesn't. So let's make sure we don't export them on BookE. This fixes a link error on BookE with CONFIG_KVM=y. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: PPC: Add helpers to call FPU instructionsAlexander Graf2010-04-251-0/+2
| | | | | | | | | | | | | To emulate paired single instructions, we need to be able to call FPU operations from within the kernel. Since we don't want gcc to spill arbitrary FPU code everywhere, we tell it to use a soft fpu. Since we know we can really call the FPU in safe areas, let's also add some calls that we can later use to actually execute real world FPU operations on the host's FPU.

* powerpc: Enable sparse irq_descs on powerpcMichael Ellerman2009-10-301-1/+0Star
| | | | | | | | | | | | | Defining CONFIG_SPARSE_IRQ enables generic code that gets rid of the static irq_desc array, and replaces it with an array of pointers to irq_descs. It also allows node local allocation of irq_descs, however we currently don't have the information available to do that, so we just allocate them on all on node 0.

* powerpc/mm: Add SMP support to no-hash TLB handlingBenjamin Herrenschmidt2008-12-211-6/+0Star
| | | | | | | | | | | | | | | | This commit moves the whole no-hash TLB handling out of line into a new tlb_nohash.c file, and implements some basic SMP support using IPIs and/or broadcast tlbivax instructions. Note that I'm using local invalidations for D->I cache coherency. At worst, if another processor is trying to execute the same and has the old entry in its TLB, it will just take a fault and re-do the TLB flush locally (it won't re-do the cache flush in any case).

* ftrace: rename FTRACE to FUNCTION_TRACERSteven Rostedt2008-10-201-1/+1
| | | | | | | | | | | | Due to confusion between the ftrace infrastructure and the gcc profiling tracer "ftrace", this patch renames the config options from FTRACE to FUNCTION_TRACER. The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.

* powerpc: Introduce local (non-broadcast) forms of tlb invalidatesKumar Gala2008-09-241-0/+3
| | | | | | | | | | | | | | | | | | | | Introduced a new set of low level tlb invalidate functions that do not broadcast invalidates on the bus: _tlbil_all - invalidate all _tlbil_pid - invalidate based on process id (or mm context) _tlbil_va - invalidate based on virtual address (ea + pid) On non-SMP configs _tlbil_all should be functionally equivalent to _tlbia and _tlbil_va should be functionally equivalent to _tlbie. The intent of this change is to handle SMP based invalidates via IPIs instead of broadcasts as the mechanism scales better for larger number of cores. On e500 (fsl-booke mmu) based cores move to using MMUCSR for invalidate alls and tlbsx/tlbwe for invalidate virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | | powerpc: Add VSX context save/restore, ptrace and signal supportMichael Neuling2008-07-011-0/+3
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the floating point save and restore code to use the VSX load/stores when VSX is available. This will make FP context save/restore marginally slower on FP only code, when VSX is available, as it has to load/store 128bits rather than just 64bits. Mixing FP, VMX and VSX code will get constant architected state. The signals interface is extended to enable access to VSR 0-31 doubleword 1 after discussions with tool chain maintainers. Backward compatibility is maintained. The ptrace interface is also extended to allow access to VSR 0-31 full registers.

* [POWERPC] Lazy interrupt disabling for 64-bit machinesPaul Mackerras2006-10-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Remove flush_dcache_all exportMatt Porter2006-08-081-4/+0Star
| | | | | | | | | | Removes the flush_dcache_all export for non coherent platforms. We removed the last in-kernel user of this years ago in arch/ppc so it no longer serves a purpose. Plus, it breaks the build at the moment. Signed-off-by: Matt Porter <mporter@embeddedalley.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] tty: Remove include of screen_info.h from tty.hJon Smirl2006-07-101-1/+1
| | | | | | | | | | | | | | | | screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.
