* KVM: consolidate ioapic/ipi interrupt delivery logicGleb Natapov2009-06-10
| | | | | | | | | | Use kvm_apic_match_dest() in kvm_get_intr_delivery_bitmask() instead of duplicating the same code. Use kvm_get_intr_delivery_bitmask() in apic_send_ipi() to figure out ipi destination instead of reimplementing the logic.

* KVM: x86: silence preempt warning on kvm_write_guest_timeMatt T. Yourst2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This issue just appeared in kvm-84 when running on 2.6.28.7 (x86-64) with PREEMPT enabled. We're getting syslog warnings like this many (but not all) times qemu tells KVM to run the VCPU: BUG: using smp_processor_id() in preemptible [00000000] code: qemu-system-x86/28938 caller is kvm_arch_vcpu_ioctl_run+0x5d1/0xc70 [kvm] Pid: 28938, comm: qemu-system-x86 2.6.28.7-mtyrel-64bit Call Trace: debug_smp_processor_id+0xf7/0x100 kvm_arch_vcpu_ioctl_run+0x5d1/0xc70 [kvm] ? __wake_up+0x4e/0x70 ? wake_futex+0x27/0x40 kvm_vcpu_ioctl+0x2e9/0x5a0 [kvm] enqueue_hrtimer+0x8a/0x110 _spin_unlock_irqrestore+0x27/0x50 vfs_ioctl+0x31/0xa0 do_vfs_ioctl+0x74/0x480 sys_futex+0xb4/0x140 sys_ioctl+0x99/0xa0 system_call_fastpath+0x16/0x1b As it turns out, the call trace is messed up due to gcc's inlining, but I isolated the problem anyway: kvm_write_guest_time() is being used in a non-thread-safe manner on preemptable kernels. Basically kvm_write_guest_time()'s body needs to be surrounded by preempt_disable() and preempt_enable(), since the kernel won't let us query any per-CPU data (indirectly using smp_processor_id()) without preemption disabled. The attached patch fixes this issue by disabling preemption inside kvm_write_guest_time().

* KVM: Enable MSI-X for KVM assigned deviceSheng Yang2009-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch finally enable MSI-X. What we need for MSI-X: 1. Intercept one page in MMIO region of device. So that we can get guest desired MSI-X table and set up the real one. Now this have been done by guest, and transfer to kernel using ioctl KVM_SET_MSIX_NR and KVM_SET_MSIX_ENTRY. 2. Information for incoming interrupt. Now one device can have more than one interrupt, and they are all handled by one workqueue structure. So we need to identify them. The previous patch enable gsi_msg_pending_bitmap get this done. 3. Mapping from host IRQ to guest gsi as well as guest gsi to real MSI/MSI-X message address/data. We used same entry number for the host and guest here, so that it's easy to find the correlated guest gsi. What we lack for now: 1. The PCI spec said nothing can existed with MSI-X table in the same page of MMIO region, except pending bits. The patch ignore pending bits as the first step (so they are always 0 - no pending). 2. The PCI spec allowed to change MSI-X table dynamically. That means, the OS can enable MSI-X, then mask one MSI-X entry, modify it, and unmask it. The patch didn't support this, and Linux also don't work in this way. 3. The patch didn't implement MSI-X mask all and mask single entry. I would implement the former in driver/pci/msi.c later. And for single entry, userspace should have reposibility to handle it. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>

* KVM: VMX: Don't intercept MSR_KERNEL_GS_BASEAvi Kivity2009-06-10
| | | | | | | | | | | | | Windows 2008 accesses this MSR often on context switch intensive workloads; since we run in guest context with the guest MSR value loaded (so swapgs can work correctly), we can simply disable interception of rdmsr/wrmsr for this MSR. A complication occurs since in legacy mode, we run with the host MSR value loaded. In this case we enable interception. This means we need two MSR bitmaps, one for legacy mode and one for long mode.

The rewrite also fixes build errors with GCC 4.4 which was changed in way incompatible with the kernel's inline assembly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever an erratum workaround is enabled, it will be applied whether or not the erratum is relevent for the CPU. This patch changes this - we check the variant and revision fields in the main ID register to determine which errata to apply. We also avoid re-applying erratum 460075 if it has already been applied. Applying this fix in non-secure mode results in the kernel failing to boot (or even do anything.) This fixes booting on some ARMv7 based platforms which otherwise silently fail.

Since operand lengths other than 32bit are required, the full implementations are only available if the ARMv6K extensions are present (for the LDREXB, LDREXH and LDREXD instructions). For ARMv6, only 32-bits cmpxchg is available. Mathieu : Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes). Make cmpxchg64_local always available. Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does. Change since v3 : - Add "memory" clobbers (thanks to Nicolas Pitre) - removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+. Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not supported by the Linux kernel currently. Put back arm < v6 cmpxchg support.

| * | | | [ARM] disable NX support for OABI-supporting kernelsRussell King2009-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our signal syscall restart handling for these kernels still uses the userspace stack to build code for restarting the syscall. Unfortunately, fixing this is non-trivial, and so for the time being, we resolve the problem by disabling NX support. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
