* [PATCH] Fix HPET operation on 32-bit NVIDIA platformsAndy Currid2006-06-082-7/+27
| | | | | | | | | | | | | | | | | | | From: "Andy Currid" <ACurrid@nvidia.com> This patch fixes a kernel panic during boot that occurs on NVIDIA platforms that have HPET enabled. When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is advertised as such in the ACPI APIC table - but an earlier workaround in the kernel was ignoring this override. The fix is to honor timer IRQ overrides from ACPI when HPET is detected on an NVIDIA platform.

| | | | | | | | | | | | | This reverts commit 5491d0f3e206beb95eeb506510d62a1dab462df1. As per Andi: "After some discussion with people who have the affected system it seems best to revert for 2.6.17. It broke a common BIOS workaround and PCI-X still doesn't work. Alternative is for people to change the BIOS which seems to be better right now." Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] i386 kdump boot cpu physical apicid fixVivek Goyal2006-05-211-0/+8
| | | | | | | | | | | | | | | | | | | | | | | o Kdump second kernel boot fails after a system crash if second kernel is UP and acpi=off and if crash occurred on a non-boot cpu. o Issue here is that MP tables report boot cpu lapic id as 0 but second kernel is booting on a different processor and MP table data is stale in this context. Hence apic_id_registered() check fails in setup_local_APIC() when called from APIC_init_uniprocessor(). o Problem is not seen if ACPI is enabled as in that case boot_cpu_physical_apicid is read from the LAPIC. o Problem is not seen with SMP kernels as well because in this case also boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()). o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC if it is a UP kernel and CRASH_DUMP is enabled.

* [PATCH] x86_64: avoid IRQ0 ioapic pin collisionKimball Murray2006-05-082-1/+16
| | | | | | | | | | | | | | | | | | The patch addresses a problem with ACPI SCI interrupt entry, which gets re-used, and the IRQ is assigned to another unrelated device. The patch corrects the code such that SCI IRQ is skipped and duplicate entry is avoided. Second issue came up with VIA chipset, the problem was caused by original patch assigning IRQs starting 16 and up. The VIA chipset uses 4-bit IRQ register for internal interrupt routing, and therefore cannot handle IRQ numbers assigned to its devices. The patch corrects this problem by allowing PCI IRQs below 16.

| | | | | | | | | | | | | | | | | | | | | | | | CPU_HOTPLUG has race conditions when we use broadcast mode IPI. - First we introduced no_broadcast option (see include/asm-i386/mach-default/mach_ipi.h) - x86_64 solved it by using physical flat mode (same as bigsmp on i386) since this will not use broadcast shortcuts for IPI. - We switched to use bigsmp on i386 so that we can have same handling as x86_64, but apparently this caused an error message, if kernel was compiled without X86_GENERICARCH, X86_BIGSMP. The message "You have >8 CPUS..." which was bogus and misleading, and only indicated one of the above ARCH wasnt selected. So we do not switch to automatic bigsmp for HOTPLUG_CPU support in i386 until the other related config dependencies for SMP_SUSPEND etc can be done right.

* [PATCH] i386/x86-64: Fix x87 information leak between processesAndi Kleen2006-04-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes. This was actually documented by AMD, but nobody recognized it as being different from Intel before. The fix first adds an optimization: instead of unconditionally calling FNCLEX after each FXSAVE test if ES is pending and skip it when not needed. Then do a x87 load from a kernel variable to clear FOP/FIP/FDP. This means other processes always will only see a constant value defined by the kernel in their FP state. I took some pain to make sure to chose a variable that's already in L1 during context switch to make the overhead of this low. Also alternative() is used to patch away the new code on CPUs who don't need it. Patch for both i386/x86-64. The problem was discovered originally by Jan Beulich. Richard Brunner provided the basic code for the workarounds, with contribution from Jan.

I have about 100 Linux boxes (all with the same (binary the same) kernel). Last time I have upgraded all those boxes from 2.4.32 to 2.6.15.6 (first 2.6.15.1, next .2, .4 and .6) and I have found some problems on VIA based PC's. Probably the reason of this is that some VIA chipsets are unrecognized by IRQ router. In line 586 there is: /* FIXME: add new ones for 8233/5 */ There were only a few of chipsets ID's there, some of my VIA chipsets were not present and kernel used default IRQ router. I have added three entries, so that the code looks like: case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: case PCI_DEVICE_ID_VIA_8233A: case PCI_DEVICE_ID_VIA_8235: case PCI_DEVICE_ID_VIA_8237: case PCI_DEVICE_ID_VIA_8237_SATA: /* FIXME: add new ones for 8233/5 */ r->name = "VIA"; r->get = pirq_via_get; r->set = pirq_via_set; return 1; } The kernel goes fine but I haven't testes it for weeks, I'm just a moment after reboot :) One thing is different (better?): Using previus kernel I had: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 0 now I have: PCI: Via IRQ fixup for 0000:00:0f.1, from 255 to 11 Maybe it is good idea to add there some more VIA chipsets?

|/ | | | | | | | | | | | | | | | | | dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64. Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes. All three architectures already set CONFIG_DMI in their top-level Kconfig files.

* [PATCH] splice: add support for sys_tee()Jens Axboe2006-04-111-0/+1
| | | | | | | | | | | | Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe. No data is copied, the output just grabs a reference to the input pipe data. Signed-off-by: Jens Axboe <axboe@suse.de>

* [PATCH] x86-64/i386: Don't process APICs/IO-APICs in ACPI when APIC is disabled.Andi Kleen2006-04-111-1/+4
| | | | | | | | | | | | | | | | | | When nolapic was passed or the local APIC was disabled for another reason ACPI would still parse the IO-APICs until these were explicitely disabled with noapic. Usually this resulted in a non booting configuration unless "nolapic noapic" was used. I also disabled the local APIC parsing in this case, although that's only cosmetic (suppresses a few printks) This hopefully makes nolapic work in all cases.

* [PATCH] vesafb: Fix incorrect logo colors in x86_64Antonino A. Daplas2006-04-111-0/+5
| | | | | | | | | | | | | | | | | | | Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR.

* [PATCH] No arch-specific strpbrk implementationsKyle McMartin2006-04-111-1/+0
| | | | | | | | | | | | | | | While cleaning up parisc_ksyms.c earlier, I noticed that strpbrk wasn't being exported from lib/string.c. Investigating further, I noticed a changeset that removed its export and added it to _ksyms.c on a few more architectures. The justification was that "other arches do it." I think this is wrong, since no architecture currently defines __HAVE_ARCH_STRPBRK, there's no reason for any of them to be exporting it themselves. Therefore, consolidate the export to lib/string.c.

* [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-111-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.
