* KVM: SVM: Add tracepoint for nested vmrunJoerg Roedel2009-12-033-0/+40
| | | | | | | | This patch adds a dedicated kvm tracepoint for a nested vmrun. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Move INTR vmexit out of atomic codeJoerg Roedel2009-12-031-1/+25
| | | | | | | | | | | | The nested SVM code emulates a #vmexit caused by a request to open the irq window right in the request function. This is a bug because the request function runs with preemption and interrupts disabled but the #vmexit emulation might sleep. This can cause a schedule()-while-atomic bug and is fixed with this patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Notify nested hypervisor of lost event injectionsAlexander Graf2009-12-031-0/+16
| | | | | | | | | | | | | If event_inj is valid on a #vmexit the host CPU would write the contents to exit_int_info, so the hypervisor knows that the event wasn't injected. We don't do this in nested SVM by now which is a bug and fixed by this patch.

* KVM: x86: include pvclock MSRs in msrs_to_saveGlauber Costa2009-12-031-4/+8
| | | | | | | | | | | | | For a while now, we are issuing a rdmsr instruction to find out which msrs in our save list are really supported by the underlying machine. However, it fails to account for kvm-specific msrs, such as the pvclock ones. This patch moves then to the beginning of the list, and skip testing them.

* KVM: x86: Rework guest single-step flag injection and filteringJan Kiszka2009-12-032-32/+48

| | | | | | | | | | | Disable paravirt MMU capability reporting, so that new (or rebooted) guests switch to native operation. Paravirt MMU is a burden to maintain and does not bring significant advantages compared to shadow anymore.

* KVM: x86: Refactor guest debug IOCTL handlingJan Kiszka2009-12-034-38/+26
| | | | | | | | | Much of so far vendor-specific code for setting up guest debug can actually be handled by the generic code. This also fixes a minor deficit in the SVM part /wrt processing KVM_GUESTDBG_ENABLE. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>

* KVM: Fix hotplug of CPUsZachary Amsden2009-12-032-4/+6
| | | | | | | | | | | Both VMX and SVM require per-cpu memory allocation, which is done at module init time, for only online cpus. Backend was not allocating enough structure for all possible CPUs, so new CPUs coming online could not be hardware enabled.

* KVM: Kill the confusing tsc_ref_khz and ref_freq variablesZachary Amsden2009-12-031-10/+16
| | | | | | | | | | | | | | | | | | They are globals, not clearly protected by any ordering or locking, and vulnerable to various startup races. Instead, for variable TSC machines, register the cpufreq notifier and get the TSC frequency directly from the cpufreq machinery. Not only is it always right, it is also perfectly accurate, as no error prone measurement is required. On such machines, when a new CPU online is brought online, it isn't clear what frequency it will start with, and it may not correspond to the reference, thus in hardware_enable we clear the cpu_tsc_khz variable to zero and make sure it is set before running on a VCPU.

* KVM: Activate Virtualization On DemandAlexander Graf2009-12-037-15/+29
| | | | | | | | | | | | | | | | | | | | | | | X86 CPUs need to have some magic happening to enable the virtualization extensions on them. This magic can result in unpleasant results for users, like blocking other VMMs from working (vmx) or using invalid TLB entries (svm). Currently KVM activates virtualization when the respective kernel module is loaded. This blocks us from autoloading KVM modules without breaking other VMMs. To circumvent this problem at least a bit, this patch introduces on demand activation of virtualization. This means, that instead virtualization is enabled on creation of the first virtual machine and disabled on destruction of the last one. So using this, KVM can be easily autoloaded, while keeping other hypervisors usable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, with PAGE_SIZE_4KB, the kernel for loongson will hang on: Kernel panic - not syncing: Attempted to kill init! The possible reason is the cache aliases problem: Loongson 2F has 64kb, 4 way L1 Cache, the way size is 16kb, which is bigger then 4kb. so, If using 4kb page size, there is cache aliases problem. To avoid this kind of problem, extra cache flushing. The 2nd possible solution is 16kb page size which avoids cache aliases without the need for extra cache flushes. So we disable 4kB pages until the aliasing issue is solved.
