2010-05-17KVM: SVM: Optimize nested svm msrpm mergingJoerg Roedel1-9/+71
This patch optimizes the way the msrpm of the host and the guest are merged. The old code merged the 2 msrpm pages completly. This code needed to touch 24kb of memory for that operation. The optimized variant this patch introduces merges only the parts where the host msrpm may contain zero bits. This reduces the amount of memory which is touched to 48 bytes.

2010-05-17KVM: SVM: Introduce direct access msr listJoerg Roedel1-10/+46
This patch introduces a list with all msrs a guest might have direct access to and changes the svm_vcpu_init_msrpm function to use this list. It also adds a check to set_msr_interception which triggers a warning if a developer changes a msr intercept that is not in the list.

2010-05-17KVM: SVM: Move msrpm offset calculation to seperate functionJoerg Roedel1-16/+37
The algorithm to find the offset in the msrpm for a given msr is needed at other places too. Move that logic to its own function. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-05-17KVM: SVM: Return correct values in nested_svm_exit_handled_msrJoerg Roedel1-5/+5
The nested_svm_exit_handled_msr() returned an bool which is a bug. I worked by accident because the exected integer return values match with the true and false values. This patch changes the return value to int and let the function return the correct values. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-05-13KVM: SVM: Fix wrong intercept masks on 32 bitJoerg Roedel1-4/+4
This patch makes KVM on 32 bit SVM working again by correcting the masks used for iret interception. With the wrong masks the upper 32 bits of the intercepts are masked out which leaves vmrun unintercepted. This is not legal on svm and the vmrun fails. Bug was introduced by commits 95ba827313 and 3cfc3092.

2010-04-25KVM: SVM: Clear exit_info for injected INTR exitsJoerg Roedel1-1/+3

2010-04-25KVM: SVM: Handle nested selective_cr0 intercept correctlyJoerg Roedel1-0/+21
If we have the following situation with nested svm: 1. Host KVM intercepts cr0 writes 2. Guest hypervisor intercepts only selective cr0 writes Then we get an cr0 write intercept which is handled on the host. But that intercepts may actually be a selective cr0 intercept for the guest. This patch checks for this condition and injects a selective cr0 intercept if needed. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2010-04-25KVM: SVM: Emulate nRIP feature when reinjecting INT3Jan Kiszka1-3/+35
When in guest debugging mode, we have to reinject those #BP software exceptions that are caused by guest-injected INT3. As older AMD processors do not support the required nRIP VMCB field, try to emulate it by moving RIP past the instruction on exception injection. Fix it up again in case the injection failed and we were able to catch this. This does not work for unintercepted faults, but it is better than doing nothing.

2010-04-25KVM: x86: Save&restore interrupt shadow maskJan Kiszka1-1/+1
The interrupt shadow created by STI or MOV-SS-like operations is part of the VCPU state and must be preserved across migration. Transfer it in the spare padding field of kvm_vcpu_events.interrupt. As a side effect we now have to make vmx_set_interrupt_shadow robust against both shadow types being set. Give MOV SS a higher priority and skip STI in that case to avoid that VMX throws a fault on next entry. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-04-25KVM: SVM: Fix wrong interrupt injection in enable_irq_windowsJoerg Roedel1-9/+8
The nested_svm_intr() function does not execute the vmexit anymore. Therefore we may still be in the nested state after that function ran.

2010-04-25KVM: SVM: Make lazy FPU switching work with nested svmJoerg Roedel1-4/+39
The new lazy fpu switching code may disable cr0 intercepts when running nested. This is a bug because the nested hypervisor may still want to intercept cr0 which will break in this situation.

2010-04-25KVM: SVM: Activate nested state only when guest state is completeJoerg Roedel1-6/+9
Certain functions called during the emulated world switch behave differently when the vcpu is running nested. This is not the expected behavior during a world switch emulation.

2010-04-25KVM: SVM: Don't sync nested cr8 to lapic and backJoerg Roedel1-15/+31
This patch makes syncing of the guest tpr to the lapic conditional on !nested. Otherwise a nested guest using the TPR could freeze the guest. Another important change this patch introduces is that the cr8 intercept bits are no longer ORed at vmrun emulation if the guest sets VINTR_MASKING in its VMCB. The reason is that nested cr8 accesses need alway be handled by the nested hypervisor because they change the shadow version of the tpr.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Enhance mov dr instruction emulation used by SVM so that it properly handles dr4/5: alias to dr6/7 if cr4.de is cleared. Otherwise return EMULATE_FAIL which will let our only possible caller in that scenario, ud_interception, re-inject UD. We do not need to inject faults, SVM does this for us (exceptions take precedence over instruction interceptions). For the same reason, the value overflow checks can be removed.

2010-03-01KVM: SVM: Lazy fpu with nptAvi Kivity1-8/+0

2010-03-01KVM: SVM: Selective cr0 interceptAvi Kivity1-6/+26
If two conditions apply: - no bits outside TS and EM differ between the host and guest cr0 - the fpu is active then we can activate the selective cr0 write intercept and drop the unconditional cr0 read and write intercept, and allow the guest to run with the host fpu state. This reduces cr0 exits due to guest fpu management while the guest fpu is loaded. Acked-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2010-03-01KVM: SVM: Restore unconditional cr0 intercept under nptAvi Kivity1-22/+7

2010-03-01KVM: SVM: Initialize fpu_active in init_vmcb()Avi Kivity1-1/+2

2010-03-01KVM: Lazify fpu activation and deactivationAvi Kivity1-14/+21
Defer fpu deactivation as much as possible - if the guest fpu is loaded, keep it loaded until the next heavyweight exit (where we are forced to unload it). This reduces unnecessary exits. We also defer fpu activation on clts; while clts signals the intent to use the fpu, we can't be sure the guest will actually use it. Signed-off-by: Avi Kivity <avi@redhat.com>

2009-12-03KVM: SVM: Reset cr0 properly on vcpu resetEduardo Habkost1-4/+5
svm_vcpu_reset() was not properly resetting the contents of the guest-visible cr0 register, causing the following issue: https://bugzilla.redhat.com/show_bug.cgi?id=525699 Without resetting cr0 properly, the vcpu was running the SIPI bootstrap routine with paging enabled, making the vcpu get a pagefault exception while trying to run it. Instead of setting vmcb->save.cr0 directly, the new code just resets kvm->arch.cr0 and calls kvm_set_cr0(). The bits that were set/cleared on vmcb->save.cr0 (PG, WP, !CD, !NW) will be set properly by svm_set_cr0(). kvm_set_cr0() is used instead of calling svm_set_cr0() directly to make sure kvm_mmu_reset_context() is called to reset the mmu to nonpaging mode.
