2011-03-17KVM: Convert kvm_lock to raw_spinlockJan Kiszka
Code under this lock requires non-preemptibility. Ensure this also over -rt by converting it to raw spinlock. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-03-17KVM: SVM: check for progress after IRET interceptionAvi Kivity
When we enable an NMI window, we ask for an IRET intercept, since the IRET re-enables NMIs. However, the IRET intercept happens before the instruction executes, while the NMI window architecturally opens afterwards. To compensate for this mismatch, we only open the NMI window in the following exit, assuming that the IRET has by then executed; however, this assumption is not always correct; we may exit due to a host interrupt or page fault, without having executed the instruction. Fix by checking for forward progress by recording and comparing the IRET's rip. This is somewhat of a hack, since an unchaging rip does not mean that no forward progress has been made, but is the simplest fix for now. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-03-17KVM: Fix race between nmi injection and enabling nmi windowAvi Kivity
The interrupt injection logic looks something like if an nmi is pending, and nmi injection allowed inject nmi if an nmi is pending request exit on nmi window the problem is that "nmi is pending" can be set asynchronously by the PIT; if it happens to fire between the two if statements, we will request an nmi window even though nmi injection is allowed. On SVM, this has disasterous results, since it causes eflags.TF to be set in random guest code. The fix is simple; make nmi_pending synchronous using the standard vcpu->requests mechanism; this ensures the code above is completely synchronous wrt nmi_pending.

2011-03-17KVM: use yield_to instead of sleep in kvm_vcpu_on_spinRik van Riel
Instead of sleeping in kvm_vcpu_on_spin, which can cause gigantic slowdowns of certain workloads, we instead use yield_to to get another VCPU in the same KVM guest to run sooner. This seems to give a 10-15% speedup in certain workloads. Signed-off-by: Rik van Riel <riel@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-03-17KVM: keep track of which task is running a KVM vcpuRik van Riel
Keep track of which task is running a KVM vcpu. This helps us figure out later what task to wake up if we want to boost a vcpu that got preempted. Unfortunately there are no guarantees that the same task always keeps the same vcpu, so we can only track the task across a single "run" of the vcpu.

2011-03-17KVM: Drop bogus x86_decode_insn() error checkAvi Kivity
x86_decode_insn() doesn't return X86EMUL_* values, so the check for X86EMUL_PROPOGATE_FAULT will always fail. There is a proper check later on, so there is no need for a replacement for this code. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-03-17KVM: x86: Drop obsolete warning about INIT on runnable VCPUJan Kiszka
This warning was once used for debugging QEMU user space. Though uncommon, it is actually possible to send an INIT request to a running VCPU. So better drop this warning before someone misuses it to flood kernel logs this way. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-03-17mm: remove is_hwpoison_addressHuang Ying
Unused. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-03-17KVM: Replace is_hwpoison_address with __get_user_pagesHuang Ying
is_hwpoison_address only checks whether the page table entry is hwpoisoned, regardless the memory page mapped. While __get_user_pages will check both. QEMU will clear the poisoned page table entry (via unmap/map) to make it possible to allocate a new memory page for the virtual address across guest rebooting. But it is also possible that the underlying memory page is kept poisoned even after the corresponding page table entry is cleared, that is, a new memory page can not be allocated. __get_user_pages can catch these situations.

2011-03-17mm: make __get_user_pages return -EHWPOISON for HWPOISON page optionallyHuang Ying
Make __get_user_pages return -EHWPOISON for HWPOISON page only if FOLL_HWPOISON is specified. With this patch, the interested callers can distinguish HWPOISON pages from general FAULT pages, while other callers will still get -EFAULT for all these pages, so the user space interface need not to be changed. This feature is needed by KVM, where UCR MCE should be relayed to guest for HWPOISON page, while instruction emulation and MMIO will be tried for general FAULT page. The idea comes from Andrew Morton.

2011-03-17mm: export __get_user_pagesHuang Ying
In most cases, get_user_pages and get_user_pages_fast should be used to pin user pages in memory. But sometimes, some special flags except FOLL_GET, FOLL_WRITE and FOLL_FORCE are needed, for example in following patch, KVM needs FOLL_HWPOISON. To support these users, __get_user_pages is exported directly. There are some symbol name conflicts in infiniband driver, fixed them too.

2011-03-17KVM: x86: handle guest access to BBL_CR_CTL3 MSRjohn cooper
A correction to Intel cpu model CPUID data (patch queued) caused winxp to BSOD when booted with a Penryn model. This was traced to the CPUID "model" field correction from 6 -> 23 (as is proper for a Penryn class of cpu). Only in this case does the problem surface. The cause for this failure is winxp accessing the BBL_CR_CTL3 MSR which is unsupported by current kvm, appears to be a legacy MSR not fully characterized yet existing in current silicon, and is apparently carried forward in MSR space to accommodate vintage code as here. It is not yet conclusive whether this MSR implements any of its legacy functionality or is just an ornamental dud for compatibility. While I found no silicon version specific documentation link to this MSR, a general description exists in Intel's developer's reference which agrees with the functional behavior of other bootloader/kernel code I've examined accessing BBL_CR_CTL3. Regrettably winxp appears to be setting bit #19 called out as "reserved" in the above document. So to minimally accommodate this MSR, kvm msr get will provide the equivalent mock data and kvm msr write will simply toss the guest passed data without interpretation. While this treatment of BBL_CR_CTL3 addresses the immediate problem, the approach may be modified pending clarification from Intel.
