* Kprobes: indicate kretprobe support in KconfigAnanth N Mavinakayanahalli2008-03-04
| | | | | | | | | | | | | | | | | Add CONFIG_HAVE_KRETPROBES to the arch/<arch>/Kconfig file for relevant architectures with kprobes support. This facilitates easy handling of in-kernel modules (like samples/kprobes/kretprobe_example.c) that depend on kretprobes being present in the kernel. Thanks to Sam Ravnborg for helping make the patch more lean. Per Mathieu's suggestion, added CONFIG_KRETPROBES and fixed up dependencies.

| * [POWERPC] Convert the cell IOMMU fixed mapping to 16M IOMMU pagesMichael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The only tricky part is we need to adjust the PTE insertion loop to cater for holes in the page table. The PTEs for each segment start on a 4K boundary, so with 16M pages we have 16 PTEs per segment and then a gap to the next 4K page boundary. It might be possible to allocate the PTEs for each segment separately, saving the memory currently filling the gaps. However we'd need to check that's OK with the hardware, and that it actually saves memory. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| * [POWERPC] Cell IOMMU: n_pte_pages is in 4K page units, not IOMMU_PAGE_SIZEMichael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | We use n_pte_pages to calculate the stride through the page tables, but we also use it to set the NPPT value in the segment table entry. That is defined as the number of 4K pages per segment, so we should calculate it as such regardless of the IOMMU page size.

| * [POWERPC] Split setup of IOMMU stab and ptab, allocate dynamic/fixed ptabs ↵Michael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | separately Currently the cell IOMMU code allocates the entire IOMMU page table in a contiguous chunk. This is nice and tidy, but for machines with larger amounts of RAM the page table allocation can fail due to it simply being too large. So split the segment table and page table setup routine, and arrange to have the dynamic and fixed page tables allocated separately.

| * [POWERPC] Use it_offset not pte_offset in cell IOMMU codeMichael Ellerman2008-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cell IOMMU tce build and free routines use pte_offset to convert the index passed from the generic IOMMU code into a page table offset. This takes into account the SPIDER_DMA_OFFSET which sets the top bit of every DMA address. However it doesn't cater for the IOMMU window starting at a non-zero address, as the base of the window is not incorporated into pte_offset at all. As it turns out tbl->it_offset already contains the value we need, it takes into account the base of the window and also pte_offset. So use it instead!

| * | [POWERPC] spufs: serialize SLB invalidation against SLB loadingArnd Bergmann2008-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a potential race between flushes of the entire SLB in the MFC and the point where new entries are being established. The problem is that we might put a ESID entry into the MFC SLB when the VSID entry has just been cleared by the global flush. This can be circumvented by holding the register_lock throughout both the flushing and the creation of SLB entries.

| * | [POWERPC] spufs: invalidate SLB translation before adding a new entryArnd Bergmann2008-02-28

The problem is that the 'valid' bit is stored in the ESID, which is always written after the VSID. Overwriting the VSID first will make the original ESID entry point to the new VSID, which means that any concurrent DMA accessing the old ESID ends up being redirected to the new virtual address. A few cycles later, we write the new ESID and everything is fine again. That race can be closed by writing a zero entry to the ESID first, which makes sure that the VSID is not accessed until we write the new ESID. Note that we don't actually need to invalidate the SLB entry using the invalidation register, which would also flush any ERAT entries for that segment, because the segment translation does not become invalid but is only removed from the SLB cache.

| * | [POWERPC] spufs: synchronize IRQ when disablingArnd Bergmann2008-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a small race between the context save procedure and the SPU interrupt handling, where we expect all interrupt processing to have finished after disabling them, while an interrupt is still being processed on another CPU. The obvious fix is to call synchronize_irq() after disabling the interrupts at the start of the context save procedure to make sure we never access the SPU any more during an ongoing save or even after that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we get the following output from sputrace: [5.097935954] 1606: spufs_ps_nopfn__enter (thread = 1605, spu = -1) [5.097958164] 1606: spufs_ps_nopfn__insert (thread = 1605, spu = 15) [5.097973529] 1607: spufs_ps_nopfn__enter (thread = 1605, spu = -1) [5.097989174] 1607: spufs_ps_nopfn__insert (thread = 1605, spu = 14) Which leads me to believe that 160[67] is the current thread ID, and 1605 is the context backing the psmap. However, the 'current' and 'owner' tids are reversed - the 'current' tid is on the right. This change puts the current thread ID in the left-hand column instead, and renames the right to 'ctxthread'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a small window where a spu context may be destroyed while we're servicing a page fault (from another thread) to the context's problem state mapping. After we up_read() the mmap_sem, it's possible that the context is destroyed by its owning thread, and so the later references to ctx are invalid. This can maifest as a deadlock on the (now free()-ed) context state mutex. This change adds a reference to the context before we release the mmap_sem, so that the context cannot be destroyed.

The final context will never be run, as the other contexts are loaded on the SPEs, none of which are repoted as free (ie, spu->alloc_state != SPU_FREE), so spu_get_idle() doesn't give us a spu to run on. Because all of the contexts are stopped, none are descheduled by the scheduler tick, as spusched_tick returns if spu_stopped(ctx). This change replaces the spu_stopped() check with checking for SCHED_IDLE in ctx->policy. We set a context's policy to SCHED_IDLE when we're not in spu_run(). We also favour SCHED_IDLE contexts when looking for contexts to unbind, but leave their timeslice intact for later resumption.

| * [POWERPC] Remove unused CONFIG_WANT_DEVICE_TREEGrant Likely2008-02-14
| | | | | | | | | | | | | | | | | | | | | | CONFIG_DEVICE_TREE was the only user of CONFIG_WANT_DEVICE_TREE but it was removed in commit id 25431333813686654907ab987fb5de10c10a16db (bootwrapper: Build multiple cuImages). This removes CONFIG_WANT_DEVICE_TREE from Kconfig and the defconfigs. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [POWERPC] Cell RAS: Remove DEBUG, and add license and copyrightMichael Ellerman2008-02-14
| | | | | | | | | | | | | | | | | | | | | | arch/powerpc/platforms/cell/ras.c still has DEBUG #defined, which is no longer necessary. Disable it - this disables two pr_debugs(). While we're there this file should have a copyright notice and license, so add both. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [POWERPC] PS3: Fix bootwrapper hang bugGeoff Levand2008-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a bug in the lv1_get_repository_node_value() routine of the PS3 bootwrapper. Changes in the PS3 system firmware 2.20 cause this bug to hang the system when branching from the bootwrapper to the kernel _start. Since the video system has not yet been enabled at the time the bug is hit, the system hangs with a blank screen. Earlier firmwares don't cause such a catastrophic failure, and so this bug went undetected. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [POWERPC] Fix DEBUG_PREEMPT warning when warningHugh Dickins2008-02-14
| | | | | | | | | | | | | | | | | | The powerpc show_regs prints CPU using smp_processor_id: change that to raw_smp_processor_id, so that when it's showing a WARN_ON backtrace without preemption disabled, DEBUG_PREEMPT doesn't mess up that warning with its own.
