Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: Move arch dependent files to new directory arch/x86/kvm/Avi Kivity24-15926/+2
This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: VMX: Add printk_ratelimit in vmx_intr_assistRyan Harper1-1/+2
Add printk_ratelimit check in front of printk. This prevents spamming of the message during 32-bit ubuntu 6.06server install. Previously, it would hang during the partition formatting stage. Signed-off-by: Ryan Harper <[email protected]> Signed-off-by: Avi Kivity <[email protected]>

2008-01-30KVM: Portability: Split mmu-related static inline functions to mmu.hZhang Xiantao7-44/+55
Since these functions need to know the details of kvm or kvm_vcpu structure, it can't be put in x86.h. Create mmu.h to hold them. Signed-off-by: Zhang Xiantao <[email protected]> Acked-by: Carsten Otte <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: Portability: Introduce kvm_vcpu_archZhang Xiantao10-581/+586

2008-01-30KVM: MMU: emulated cmpxchg8b should be atomic on i386Marcelo Tosatti1-0/+26
Emulate cmpxchg8b atomically on i386. This is required to avoid a guest pte walker from seeing a splitted write. [avi: make it compile] Signed-off-by: Marcelo Tosatti <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: SVM: support writing 0 to K8 performance counter control registersJoerg Roedel1-0/+13
This lets SVM ignore writes of the value 0 to the performance counter control registers. Thus enabling them will still fail in the guest, but a write of 0 which keeps them disabled is accepted. This is required to boot Windows Vista 64bit. [avi: avoid fall-thru in switch statement] Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Markus Rechberger <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: LAPIC: minor debugging compile fixJoerg Roedel1-1/+1
This patch fixes a compile error of the LAPIC code with APIC debugging enabled. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Markus Rechberger <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Fix SMP shadow instantiation raceMarcelo Tosatti2-12/+29
There is a race where VCPU0 is shadowing a pagetable entry while VCPU1 is updating it, which results in a stale shadow copy. Fix that by comparing the contents of the cached guest pte with the current guest pte after write-protecting the guest pagetable. Signed-off-by: Marcelo Tosatti <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: SVM: Exit to userspace if write to cr8 and not using in-kernel apicJoerg Roedel1-1/+10
With this patch KVM on SVM will exit to userspace if the guest writes to CR8 and the in-kernel APIC is disabled. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Markus Rechberger <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Use mmu_set_spte() for real-mode shadowsAvi Kivity1-31/+10
In addition to removing some duplicated code, this also handles the unlikely case of real-mode code updating a guest page table. This can happen when one vcpu (in real mode) touches a second vcpu's (in protected mode) page tables, or if a vcpu switches to real mode, touches page tables, and switches back. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Adjust mmu_set_spte() debug code for gpte removalAvi Kivity1-2/+2
Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Move set_pte() into guest paging mode independent codeAvi Kivity2-88/+88
As set_pte() no longer references either a gpte or the guest walker, we can move it out of paging mode dependent code (which compiles twice and is generally nasty). Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Remove walker argument to set_pte()Avi Kivity1-4/+3
Unused. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Pass pte dirty flag to set_pte() instead of calculating it on-siteAvi Kivity1-10/+7
This allows us to remove its dependency on pt_element_t. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: No need to pick up nx bit from guest pteAvi Kivity1-1/+0
We already set it according to cumulative access permissions. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Fix inherited permissions for emulated guest pte updatesAvi Kivity3-5/+7
When we emulate a guest pte write, we fail to apply the correct inherited permissions from the parent ptes. Now that we store inherited permissions in the shadow page, we can use that to update the pte permissions correctly. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Move pte access calculation into a helper functionAvi Kivity1-7/+13
Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Set nx bit correctly on shadow ptesAvi Kivity1-0/+2
While the page table walker correctly generates a guest page fault if a guest tries to execute a non-executable page, the shadow code does not mark it non-executable. This means that if a guest accesses an nx page first with a read access, then subsequent code fetch accesses will succeed. Fix by setting the nx bit on shadow ptes. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Simplify calculation of pte accessAvi Kivity2-29/+43
The nx bit is awkwardly placed in the 63rd bit position; furthermore it has a reversed meaning compared to the other bits, which means we can't use a bitwise and to calculate compounded access masks. So, we simplify things by creating a new 3-bit exec/write/user access word, and doing all calculations in that. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Use cmpxchg for pte updates on walk_addr()Marcelo Tosatti1-2/+34
In preparation for multi-threaded guest pte walking, use cmpxchg() when updating guest pte's. This guarantees that the assignment of the dirty bit can't be lost if two CPU's are faulting the same address simultaneously. [avi: fix kunmap_atomic() parameters] Signed-off-by: Marcelo Tosatti <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: SVM: Trap access to the cr8 registerAvi Kivity2-2/+7
Later we may be able to use the virtual tpr feature, but for now, just trap it. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: x86 emulator: Fix stack instructions on 64-bit modeAvi Kivity1-12/+15
Stack instructions are always 64-bit on 64-bit mode; many of the emulated stack instructions did not take that into account. Fix by adding a 'Stack' bitflag and setting the operand size appropriately during the decode stage (except for 'push r/m', which is in a group with a few other instructions, so it gets its own treatment). This fixes random crashes on Vista x64. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: SVM: Emulate read/write access to cr8Joerg Roedel1-0/+5
This patch adds code to emulate the access to the cr8 register to the x86 instruction emulator in kvm. This is needed on svm, where there is no hardware decode for control register access. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Markus Rechberger <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: VMX: Avoid exit when setting cr8 if the local apic is in the kernelAvi Kivity1-0/+2
With apic in userspace, we must exit to userspace after a cr8 write in order to update the tpr. But if the apic is in the kernel, the exit is unnecessary. Noticed by Joerg Roedel. Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: x86 emulator: fix eflags preparation for emulationAvi Kivity1-15/+15
We prepare eflags for the emulated instruction, then clobber it with an 'andl'. Fix by popping eflags as the last thing in the sequence. Patch taken from Xen (16143:959b4b92b6bf) Signed-off-by: Avi Kivity <[email protected]>

Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: Generalize exception injection mechanismAvi Kivity4-1/+86
Instead of each subarch doing its own thing, add an API for queuing an injection, and manage failed exception injection centerally (i.e., if an inject failed due to a shadow page fault, we need to requeue it). Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: MMU: Remove unused prev_shadow_ent variable from fetch()Marcelo Tosatti1-3/+0

2008-01-30KVM: Extend ioapic code to support iosapicZhang Xiantao1-0/+5
iosapic supports an additional mmio EOI register compared to ioapic. Signed-off-by: Zhang Xiantao <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: Replace dest_Lowest_Prio and dest_Fixed with self-defined macrosZhang Xiantao2-8/+13
Change dest_Loest_Prio -> IOAPIC_LOWEST_PRIORITY dest_Fixed -> IOAPIC_FIXED the original names are x86 specific, while the ioapic code will be reused for ia64. Signed-off-by: Zhang Xiantao <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: Replace kvm_lapic with kvm_vcpu in ioapic/lapic interfaceZhang Xiantao3-17/+29
This patch replaces lapic structure with kvm_vcpu in ioapic.c, making ioapic independent of the local apic, as required by ia64. Signed-off-by: Zhang Xiantao <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2008-01-30KVM: SVM: Remove KVM specific defines for MSR_EFERCarlo Marcelo Arenas Belon1-10/+7
This patch removes the KVM specific defines for MSR_EFER that were being used in the svm support file and migrates all references to use instead the ones from the kernel headers that are used everywhere else and that have the same values.

2008-01-30KVM: Export include/linux/kvm.h only if $ARCH actually supports KVMAvi Kivity1-2/+5
Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm.h only if the arch actually supports it. Signed-off-by: Avi Kivity <[email protected]>
