2007-04-25ACPI: prevent ACPI quirk warning mass spamming in logsThierry Vignaud1-1/+4
The following patch prevent this warning to be displayed again & again (eg: nine times on my NForce2 motherboard) and thus improve signal to noise ratio in logs. The ATI quirk below probably needs a similar "fix" but I don't have the hardware to test. Btw arch/x86_64/kernel/early-quirks.c::nvidia_bugs() would probably need to be synced (but I don't have an x86_64 NVidia motherboard to boot test it). Still it shows the usefullity of the recent x86 merge thread.

2007-03-08[PATCH] ACPI: repair nvidia early quirk breakage on x86_64Len Brown1-6/+1
x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET. However, the quirk works by checking for _not_ finding the HPET... Delete the nvidia_hpet_detected flag and simply test for not finding the HPET, which is simple to do now that acpi_table_parse returns 1 on failure.

2006-12-07[PATCH] x86: fix the irqbalance quirk for E7320/E7520/E7525Siddha, Suresh B1-0/+21
Move the irqbalance quirks for E7320/E7520/E7525(Errata 23 in http://download.intel.com/design/chipsets/specupdt/30304203.pdf) to early quirks. And add a PCI quirk for these platforms to check(which happens very late during the boot) if the APIC routing is indeed set to default flat mode. This fixes the breakage(in x86_64) of this quirk due to cpu hotplug which selects physical mode instead of the logical flat(as needed for this errata workaround).

2006-11-14[PATCH] x86: Add acpi_user_timer_override option for Asus boardsAndi Kleen1-1/+7
Timer overrides are normally disabled on Nvidia board because they are commonly wrong, except on new ones with HPET support. Unfortunately there are quite some Asus boards around that don't have HPET, but need a timer override. We don't know yet how to handle this transparently, but at least add a command line option to force the timer override and let them boot.

2006-09-26[PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing ↵Andi Kleen1-1/+5
conf1 Some buggy systems can machine check when config space accesses happen for some non existent devices. i386/x86-64 do some early device scans that might trigger this. Allow pci=noearly to disable this. Also when type 1 is disabling also don't do any early accesses which are always type1. This moves the pci= configuration parsing to be a early parameter. I don't think this can break anything because it only changes a single global that is only used by PCI.

2006-06-08[PATCH] Fix HPET operation on 32-bit NVIDIA platformsAndy Currid1-3/+20
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.

2006-03-08[PATCH] i386: port ATI timer fix from x86_64 to i386 IIAndi Kleen1-0/+8
ATI chipsets tend to generate double timer interrupts for the local APIC timer when both the 8254 and the IO-APIC timer pins are enabled. This is because they route it to both and the result is anded together and the CPU ends up processing it twice. This patch changes check_timer to disable the 8254 routing for interrupt 0. I think it would be safe on all chipsets actually (i tested it on a couple and it worked everywhere) and Windows seems to do it in a similar way, but to be conservative this patch only enables this mode on ATI (and adds options to enable/disable too) Ported over from a similar x86-64 change. I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but tweaked it a bit to work even without ACPI. Inspired by a patch from Chuck Ebbert, but redone.

2005-09-14Partially revert "Fix time going twice as fast problem on ATI Xpress chipsets"Linus Torvalds1-10/+0
Commit 66759a01adbfe8828dd063e32cf5ed3f46696181 introduced the fix for time ticking too fast on some boards by disabling one of the doubly connected timer pins on ATI boards. However, it ends up being _much_ too broad a brush, and that just makes some other ATI boards not work at all since they now have no timer source. So disable the automatic ATI southbridge detection, and just rely on people who see this problem disabling it by hand with the option "disable_timer_pin_1" on the kernel command line. Maybe somebody can figure out the proper tests at a later date. Acked-by: Peter Osterlund <petero2@telia.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
