2006-03-25[PATCH] x86_64: Always use IO-APIC routing for timer.Andi Kleen1-1/+1
I tested it on a couple of chipsets and it worked everywhere so it should be ok as default for now. So far I haven't done the great purge of the useless old check_timer code yet though. Can be overwritten with enable_8254_timer in the worst case Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-25[PATCH] x86_64: Patch to make the head.S-must-be-first-in-vmlinux order explicitArjan van de Ven2-0/+2
This patch puts the code from head.S in a special .bootstrap.text section. I'm working on a patch to reorder the functions in the kernel (I'll post that later), but for x86-64 at least the kernel bootstrap requires that the head.S functions are on the very first page/pages of the kernel text. This is understandable since the bootstrap is complex enough already and not a problem at all, it just means they aren't allowed to be reordered. This patch puts these special functions into a separate section to document this, and to guarantee this in the light of possibly reordering the rest later. (So this patch doesn't fix a bug per se, but makes things more robust by making the order of these functions explicit) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

There are more and more cases where we need to know DMI information early to work around bugs. i386 already had early DMI scanning, but x86-64 didn't. Implement this now.

2006-03-25[PATCH] x86_64: Clean up and tweak ACPI blacklist year codeAndi Kleen3-21/+38
- Move the core parser into dmi_scan.c. It can be useful for other subsystems too. - Differentiate between field doesn't exist and field is 0 or unparseable. The first case is likely an old BIOS with broken ACPI, the later is likely a slightly buggy BIOS where someone forget to edit the date. Don't blacklist in the later case.

2006-03-25[PATCH] x86_64: prefetch the mmap_sem in the fault pathArjan van de Ven1-2/+4
In a micro-benchmark that stresses the pagefault path, the down_read_trylock on the mmap_sem showed up quite high on the profile. Turns out this lock is bouncing between cpus quite a bit and thus is cache-cold a lot. This patch prefetches the lock (for write) as early as possible (and before some other somewhat expensive operations). With this patch, the down_read_trylock basically fell out of the top of profile.

2006-03-25[PATCH] x86_64: to use lapic ids instead of initial apic idsRavikiran G Thirumalai1-2/+2
phys_proc_id[] on AMD boxes is right now populated with the initial apic id, obtained by the cpuid instruction. But, the initial apic id need not be the local apic id on clustered APIC systems (see comment at x86_64/kernel/genapic_cluster.c, line 110). On vSMPowered with AMD CPUs the cpu_to_node will turn out to be incorrect (as apicid_to_node[] is indexed by the initial apic id rather than the local apic id). On vSMPowered boxes with Intel CPUs this is working correctly as phys_proc_id[] is initialized correctly in detect_ht(). This fixes AMD boot path according to specification, to use the correct routines for local apic id and socket ids. We use hard_smp_processor_id() to read the local apic id, and phys_pkg_id() to determine socket id for phys_proc_id[] Patch tested on Tyan multicore boxes as well as vSMPowered boxes.

gcc should handle this anyways, and it causes problems when sprintf is turned into strcpy by gcc behind our backs and the C fallback version of strcpy is actually defining __builtin_strcpy Then drop -ffreestanding from the main Makefile because it isn't needed anymore and implies -fno-builtin, which is wrong now.

2006-03-25[PATCH] x86_64: actively synchronize vmalloc area when registering certain callbacksJan Beulich5-13/+95
While the modular aspect of the respective i386 patch doesn't apply to x86-64 (as the top level page directory entry is shared between modules and the base kernel), handlers registered with register_die_notifier() are still under similar constraints for touching ioremap()ed or vmalloc()ed memory. The likelihood of this problem becoming visible is of course significantly lower, as the assigned virtual addresses would have to cross a 2**39 byte boundary. This is because the callback gets invoked (a) in the page fault path before the top level page table propagation gets carried out (hence a fault to propagate the top level page table entry/entries mapping to module's code/data would nest infinitly) and (b) in the NMI path, where nested faults must absolutely not happen, since otherwise the IRET from the nested fault re-enables NMIs, potentially resulting in nested NMI occurences.

Minor cleanup to lend better for physical CPU hotplug. Earlier way of using num_processors as index doesnt fit if CPUs come and go. This makes the code little bit better to read, and helps physical hotplug use the same functions as boot. Reserving CPU0 for BSP is too late to be done in smp_prepare_boot_cpu().

2006-03-25[PATCH] x86_64: save FPU context slightly laterJan Beulich1-3/+4
Touching of the floating point state in a kernel debugger must be NMI-safe, specifically math_state_restore() must be able to deal with being called out of an NMI context.
