2010-10-24KVM: MMU: Track page fault data in struct vcpuJoerg Roedel2-6/+12
This patch introduces a struct with two new fields in vcpu_arch for x86: * fault.address * fault.error_code This will be used to correctly propagate page faults back into the guest when we could have either an ordinary page fault or a nested page fault. In the case of a nested page fault the fault-address is different from the original address that should be walked. So we need to keep track about the real fault-address.

2010-10-24KVM: MMU: Introduce inject_page_fault function pointerJoerg Roedel1-0/+3
This patch introduces an inject_page_fault function pointer into struct kvm_mmu which will be used to inject a page fault. This will be used later when Nested Nested Paging is implemented. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: MMU: Introduce get_cr3 function pointerJoerg Roedel1-0/+1
This function pointer in the MMU context is required to implement Nested Nested Paging. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: X86: Introduce a tdp_set_cr3 functionJoerg Roedel1-0/+2
This patch introduces a special set_tdp_cr3 function pointer in kvm_x86_ops which is only used for tpd enabled mmu contexts. This allows to remove some hacks from svm code. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: MMU: Make set_cr3 a function pointer in kvm_mmuJoerg Roedel1-0/+1
This is necessary to implement Nested Nested Paging. As a side effect this allows some cleanups in the SVM nested paging code. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: MMU: Make tdp_enabled a mmu-context parameterJoerg Roedel1-0/+1
This patch changes the tdp_enabled flag from its global meaning to the mmu-context and renames it to direct_map there. This is necessary for Nested SVM with emulation of Nested Paging where we need an extra MMU context to shadow the Nested Nested Page Table.

2010-10-24KVM: x86 emulator: get rid of "restart" in emulation context.Gleb Natapov1-1/+3
x86_emulate_insn() will return 1 if instruction can be restarted without re-entering a guest. Signed-off-by: Gleb Natapov <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: x86: Fix a possible backwards warp of kvmclockZachary Amsden1-0/+2
Kernel time, which advances in discrete steps may progress much slower than TSC. As a result, when kvmclock is adjusted to a new base, the apparent time to the guest, which runs at a much higher, nsec scaled rate based on the current TSC, may have already been observed to have a larger value (kernel_ns + scaled tsc) than the value to which we are setting it (kernel_ns + 0). We must instead compute the clock as potentially observed by the guest for kernel_ns to make sure it does not go backwards.

2010-10-24x86: pvclock: Move scale_delta into common headerZachary Amsden1-0/+38
The scale_delta function for shift / multiply with 31-bit precision moves to a common header so it can be used by both kernel and kvm module. Signed-off-by: Zachary Amsden <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: x86: Unify TSC logicZachary Amsden1-2/+3
Move the TSC control logic from the vendor backends into x86.c by adding adjust_tsc_offset to x86 ops. Now all TSC decisions can be done in one place. Signed-off-by: Zachary Amsden <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: x86: TSC reset compensationZachary Amsden1-0/+3
Attempt to synchronize TSCs which are reset to the same value. In the case of a reliable hardware TSC, we can just re-use the same offset, but on non-reliable hardware, we can get closer by adjusting the offset to match the elapsed time. Signed-off-by: Zachary Amsden <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: x86: Move TSC offset writes to common codeZachary Amsden1-0/+3
Also, ensure that the storing of the offset and the reading of the TSC are never preempted by taking a spinlock. While the lock is overkill now, it is useful later in this patch series. Signed-off-by: Zachary Amsden <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: x86: Drop vm_init_tscZachary Amsden1-1/+0
This is used only by the VMX code, and is not done properly; if the TSC is indeed backwards, it is out of sync, and will need proper handling in the logic at each and every CPU change. For now, drop this test during init as misguided. Signed-off-by: Zachary Amsden <[email protected]> Signed-off-by: Marcelo Tosatti <[email protected]>
2010-10-24KVM: replace x86 kvm n_free_mmu_pages with n_used_mmu_pagesDave Hansen1-1/+1
Doing this makes the code much more readable. That's borne out by the fact that this patch removes code. "used" also happens to be the number that we need to return back to the slab code when our shrinker gets called. Keeping this value as opposed to free makes the next patch simpler. So, 'struct kvm' is kzalloc()'d. 'struct kvm_arch' is a structure member (and not a pointer) of 'struct kvm'. That means they start out zeroed. I _think_ they get initialized properly by kvm_mmu_change_mmu_pages(). But, that only happens via kvm ioctls. Another benefit of storing 'used' intead of 'free' is that the values are consistent from the moment the structure is allocated: no negative "used" value.

2010-10-24KVM: rename x86 kvm->arch.n_alloc_mmu_pagesDave Hansen1-1/+1
arch.n_alloc_mmu_pages is a poor choice of name. This value truly means, "the number of pages which _may_ be allocated". But, reading the name, "n_alloc_mmu_pages" implies "the number of allocated mmu pages", which is dead wrong. It's really the high watermark, so let's give it a name to match: nr_max_mmu_pages. This change will make the next few patches much more obvious and easy to read.

2010-10-24KVM: x86 emulator: Allow accessing IDT via emulator opsMohammed Gamal1-0/+1
The patch adds a new member get_idt() to x86_emulate_ops. It also adds a function to get the idt in order to be used by the emulator. This is needed for real mode interrupt injection and the emulation of int instructions. Signed-off-by: Mohammed Gamal <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: Move kvm_guest_init out of generic codeAlexander Graf1-0/+6
Currently x86 is the only architecture that uses kvm_guest_init(). With PowerPC we're getting a second user, but the signature is different there and we don't need to export it, as it uses the normal kernel init framework. So let's move the x86 specific definition of that function over to the x86 specfic header file. Signed-off-by: Alexander Graf <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-10-24KVM: x86 emulator: Decode memory operands directly into a 'struct operand'Avi Kivity1-3/+0

2010-10-24KVM: x86 emulator: use correct type for memory address in operandsAvi Kivity1-1/+4

2010-10-23x86: apic: Move probe_nr_irqs_gsi() into ioapic_init_mappings()Thomas Gleixner1-4/+1
probe_br_irqs_gsi() is called right after ioapic_init_mappings() and there are no other users. Move it into ioapic_init_mappings() so the declaration can disappear and the function can become static.

2010-10-23x86: Allow platforms to force enable apicThomas Gleixner1-0/+1
Some embedded x86 platforms don't setup the APIC in the BIOS/bootloader and would be forced to add "lapic" on the kernel command line. That's a bit akward. Split out the force enable code from detect_init_APIC() and allow platform code to call it from the platform setup. That avoids the command line parameter and possible replication of the MSR dance in the force enable code.
