* [PATCH] KVM: Improve interrupt responseDor Laor2007-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | The current interrupt injection mechanism might delay an interrupt under the following circumstances: - if injection fails because the guest is not interruptible (rflags.IF clear, or after a 'mov ss' or 'sti' instruction). Userspace can check rflags, but the other cases or not testable under the current API. - if injection fails because of a fault during delivery. This probably never happens under normal guests. - if injection fails due to a physical interrupt causing a vmexit so that it can be handled by the host. In all cases the guest proceeds without processing the interrupt, reducing the interactive feel and interrupt throughput of the guest. This patch fixes the situation by allowing userspace to request an exit when the 'interrupt window' opens, so that it can re-inject the interrupt at the right time. Guest interactivity is very visibly improved.

* [PATCH] KVM: Recover after an arch module load failureYoshimi Ichiyanagi2007-01-06
| | | | | | | | | | | | If we load the wrong arch module, it leaves behind kvm_arch_ops set, which prevents loading of the correct arch module later. Fix be not setting kvm_arch_ops until we're sure it's good.

* [PATCH] KVM: Fix GFP_KERNEL alloc in atomic section bugIngo Molnar2007-01-06
| | | | | | | | | | | | | | KVM does kmalloc() in an atomic section while having preemption disabled via vcpu_load(). Fix this by moving the ->*_msr setup from the vcpu_setup method to the vcpu_create method. (This is also a small speedup for setting up a vcpu, which can in theory be more frequent than the vcpu_create method).

* [PATCH] via82cxxx: fix cable detectionBartlomiej Zolnierkiewicz2007-01-06
| | | | | | | | | | | | | | | | This patch fixes 2.6.15 regression, is straightforward and tested. Cable detection got broken probably while converting the driver to support multiple controllers. Cable detection is done by examining how BIOS configured the attached devices. The current code is broken in that it examines the status *after* modifying Clk66 configuration ending up detecting 40c cables as 80c. This patch fixes it.

* [PATCH] PCI: prevent down_read when pci_devices is emptyArd van Breemen2007-01-06
| | | | | | | | | | | | | | | | | | | | The pci_find_subsys gets called very early by obsolete ide setup parameters. This is a bogus call since pci is not initialized yet, so the list is empty. But in the mean time, interrupts get enabled by down_read. This can result in a kernel panic when the irq controller gets initialized. This patch checks if the device list is empty before taking the semaphore, and hence will not enable irq's. Furthermore it will inform that it is called while pci_devices is empty as a reminder that the ide code needs to be fixed. The pci_get_subsys can get called in the same manner, and as such is patched in the same manner.

* [PATCH] kernelparams: detect if and which parameter parsing enabled irq'sArd van Breemen2007-01-06
| | | | | | | | | | | | | | The parsing of some kernel parameters seem to enable irq's at a stage that irq's are not supposed to be enabled (Particularly the ide kernel parameters). Having irq's enabled before the irq controller is initialized might lead to a kernel panic. This patch only detects this behaviour and warns about wich parameter caused it.

(In fact, on all hardware we've seen, the GTT is 512KB to the aperture's 256MB). A previous commit forced the aperture size to 512MB on G965 to match GTT, which would likely result in hangs at best if users tried to rely on agpgart's aperture size information. Instead, we use the resource length for the aperture size and the system's reported GTT size when available for the GTT size. Because the MSAC registers which had been read for aperture size detection on i9xx chips just cause a change in the resource size, we can use generic code for aperture detection on all i9xx.

A number of global cache flushes are removed as well as some PCI posting flushes. The following guidelines have been used: 1) Memory that is only mapped uncached and that has been subject to a global cache flush after the mapping was changed to uncached does not need any more cache flushes. Neither before binding to the aperture nor after unbinding. 2) Only do one PCI posting flush after a sequence of writes modifying page entries in the GATT.

At start guess_fsb function is guessing 200MHz FSB too. It is better to make it in this way because, thanks to this function, driver will fail for bogus FSB values caused by bogus multiplier value. For PowerSaver processors we can't depend on Max / MinMHzFSB because these values are only used for PowerSaver 2.0 and 3.0. Most processors on which Longhaul is used are PowerSaver 1.0 only. I'm changing code for older CPU's too, but not so much as previously, and this code was already used for Ezra. Using MinMHzBR for Ezra-T is outside spec. It is for voltage scaling purpose and don't have to be equal to minmult (but it is). Same for Nehemiah (it isn't for sure). Added mult - current multiplier value.

My assumption that this register isn't present at "PowerSaver" motherboards is so far true, but current code will not work correctly in other case. There are three possible supports: ACPI C3, PM2 and northbridge. That was my assumption that ACPI C3 and northbridge is for PS and northbridge and PM2 is for V1. In current code we can only check if it is ACPI support or not by port22_en. So remove port22_en and add longhaul_flags. If USE_ACPI_C3 and USE_NORTHBRIDGE are both clear then it means ACPI PM2 support. Also change order of support probe from ACPI C3, PM2, northbridge to ACPI C3, northbridge, ACPI PM2. Paranoid protection against port 0x22 cast as ACPI PM2 register. Bit 1 clear in such case - lockup on AGP DMA. And obvious (now) fixup for do_powersaver. Use cx->address only for ACPI C3 ("PowerSaver" processor using PM2 support). Signed-off-by: Rafa¿ Bilski <rafalbilski@interia.pl> Signed-off-by: Dave Jones <davej@redhat.com>
