2005-11-16[PATCH] powerpc: Make the vDSO functions set error code (#2)Benjamin Herrenschmidt
The vDSO functions should have the same calling convention as a syscall. Unfortunately, they currently don't set the cr0.so bit which is used to indicate an error. This patch makes them clear this bit unconditionally since all functions currently succeed. The syscall fallback done by some of them will eventually override this if the syscall fails. This also changes the symbol version of all vdso exports to make sure glibc can differenciate between old and fixed calls for existing ones like __kernel_gettimeofday.

2005-11-16[PATCH] ppc: Fix boot with yaboot with ARCH=ppcBenjamin Herrenschmidt
The merge of machine types broke boot with yaboot & ARCH=ppc due to the old code still retreiving the old-syle machine type passed in by yaboot. This patch fixes it by translating those old numbers. Since that whole mecanism is deprecated, this is a temporary fix until ARCH=ppc uses the new prom_init that the merged architecture now uses for both ppc32 and ppc64 (after 2.6.15) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-16[PATCH] PowerBook 6,1: headphone not detected after suspendGuido Guenther
ever since suspend to disk works I had the problem that headphone (un)plugging doesn't get detected properly anymore after the first resume. Reloading the module worked around this ever since, however the real cause of the problem was that after a resume the driver only got interrupts on "unplug" not on "plug". Reactivating the headphone status interrupt in tumbler_resume fixes this. This shouldn't cause any trouble with software suspend, but it would be nice if somebody could confirm this: Signed-off-by: Guido Guenther <agx@sigxcpu.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-16[PATCH] powerpc: pci_64 fixes & cleanupsBenjamin Herrenschmidt
I discovered that in some cases (PowerMac for example) we wouldn't properly map the PCI IO space on recent kernels. In addition, the code for initializing PCI host bridges was scattered all over the place with some duplication between platforms. This patch fixes the problem and does a small cleanup by creating a pcibios_alloc_controller() in pci_64.c that is similar to the one in pci_32.c (just takes an additional device node argument) that takes care of all the grunt allocation and initialisation work. It should work for both boot time and dynamically allocated PHBs. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-11-16[PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbieMarcelo Tosatti
Currently 8xx fails to boot due to endless pagefaults. Seems the bug is exposed by the change which avoids flushing the TLB when not necessary (in case the pte has not changed), introduced recently: __handle_mm_fault(): entry = pte_mkyoung(entry); if (!pte_same(old_entry, entry)) { ptep_set_access_flags(vma, address, pte, entry, write_access); update_mmu_cache(vma, address, entry); lazy_mmu_prot_update(entry); } else { /* * This is needed only for protection faults but the arch code * is not yet telling us if this is a protection fault or not. * This still avoids useless tlb flushes for .text page faults * with threads. */ if (write_access) flush_tlb_page(vma, address); } The "update_mmu_cache()" call was unconditional before, which caused the TLB to be flushed by: if (pfn_valid(pfn)) { struct page *page = pfn_to_page(pfn); if (!PageReserved(page) && !test_bit(PG_arch_1, &page->flags)) { if (vma->vm_mm == current->active_mm) { #ifdef CONFIG_8xx /* On 8xx, cache control instructions (particularly * "dcbst" from flush_dcache_icache) fault as write * operation if there is an unpopulated TLB entry * for the address in question. To workaround that, * we invalidate the TLB here, thus avoiding dcbst * misbehaviour. */ _tlbie(address); #endif __flush_dcache_icache((void *) address); } else flush_dcache_icache_page(page); set_bit(PG_arch_1, &page->flags); } Which worked to due to pure luck: PG_arch_1 was always unset before, but now it isnt. The root of the problem are the changes against the 8xx TLB handlers introduced during v2.6. What happens is the TLBMiss handlers load the zeroed pte into the TLB, causing the TLBError handler to be invoked (thats two TLB faults per pagefault), which then jumps to the generic MM code to setup the pte. The bug is that the zeroed TLB is not invalidated (the same reason for the "dcbst" misbehaviour), resulting in infinite TLBError faults. The "two exception" approach requires a TLB flush (to nuke the zeroed TLB) at each PTE update for correct behaviour: Signed-off-by: Marcelo Tosatti <marcelo.tosatti@cyclades.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-11-15[PATCH] powerpc: Fix sparsemem with memory holes [was Re: ppc64 oops..]Paul Mackerras
This patch should fix the crashes we have been seeing on 64-bit powerpc systems with a memory hole when sparsemem is enabled. I'd appreciate it if people who know more about NUMA and sparsemem than me could look over it. There were two bugs. The first was that if NUMA was enabled but there was no NUMA information for the machine, the setup_nonnuma() function was adding a single region, assuming memory was contiguous. The second was that the loops in mem_init() and show_mem() assumed that all pages within the span of a pgdat were valid (had a valid struct page). I also fixed the incorrect setting of num_physpages that Mike Kravetz pointed out. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-11-15[PATCH] ia64: cpu_idle performance bug fixChen, Kenneth W
Our performance validation on 2.6.15-rc1 caught a disastrous performance regression on ia64 with netperf (-98%) and volanomark (-58%) compares to previous kernel version 2.6.14-git7. See the following chart (result group 1 & 2). http://kernel-perf.sourceforge.net/results.machine_id=26.html We have root caused it to commit 64c7c8f88559624abdbe12b5da6502e8879f8d28 This changeset broke the ia64 task resched notification. In sched.c:resched_task(), a reschedule IPI is conditioned upon TIF_POLLING_NRFLAG. However, the above changeset unconditionally set the polling thread flag for idle tasks regardless whether pal_halt_light is in use or not. As a result, resched IPI is not sent from resched_task(). And since the default behavior on ia64 is to use pal_halt_light, we end up delaying the rescheduling task until next timer tick, and thus cause the performance regression. This fixes the performance bug. I'm glad our performance suite is turning up bad performance bug like this in time.
