When a vcpu is reset, kvmclock page keeps being written to this days. This is wrong and inconsistent: a cpu reset should take it to its initial state. Signed-off-by: Glauber Costa <glommer@redhat.com> CC: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

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.

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.

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.

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.

Currently we keep track of only two states: guest mode and host mode. This patch adds an "exiting guest mode" state that tells us that an IPI will happen soon, so unless we need to wait for the IPI, we can avoid it completely. Also 1: No need atomically to read/write ->mode in vcpu's thread 2: reorganize struct kvm_vcpu to make ->mode and ->requests in the same cache line explicitly Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>

On some CPUs, a ple_gap of 41 is simply insufficient to ever trigger PLE exits, even with the minimalistic PLE test from kvm-unit-tests. http://git.kernel.org/?p=virt/kvm/kvm-unit-tests.git;a=commitdiff;h=eda71b28fa122203e316483b35f37aaacd42f545 For example, the Xeon X5670 CPU needs a ple_gap of at least 48 in order to get pause loop exits: # modprobe kvm_intel ple_gap=47 # taskset 1 /usr/local/bin/qemu-system-x86_64 \ -device testdev,chardev=log -chardev stdio,id=log \ -kernel x86/vmexit.flat -append ple-round-robin -smp 2 VNC server running on `::1:5900' enabling apic enabling apic ple-round-robin 58298446 # rmmod kvm_intel # modprobe kvm_intel ple_gap=48 # taskset 1 /usr/local/bin/qemu-system-x86_64 \ -device testdev,chardev=log -chardev stdio,id=log \ -kernel x86/vmexit.flat -append ple-round-robin -smp 2 VNC server running on `::1:5900' enabling apic enabling apic ple-round-robin 36616 Increase the ple_gap to 128 to be on the safe side.

When emulating real mode we play with tr hidden state, but leave tr.selector alone. That works well, except for save/restore, since loading TR writes it to the hidden state in vmx->rmode. Fix by also saving and restoring the tr selector; this makes things more consistent and allows migration to work during the early boot stages of Windows XP.
