KVM: selftests: Introduce steal-time test

2020-03-16T16:59:07Z

The steal-time test confirms what is reported to the guest as stolen time is consistent with the run_delay reported for the VCPU thread on the host. Both x86_64 and AArch64 have the concept of steal/stolen time so this test is introduced for both architectures. While adding the test we ensure .gitignore has all tests listed (it was missing s390x/resets) and that the Makefile has all tests listed in alphabetical order (not really necessary, but it almost was already...). We also extend the common API with a new num-guest- pages call and a new timespec call. Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

KVM: selftests: Add test for KVM_SET_USER_MEMORY_REGION

2020-03-16T16:57:27Z

Add a KVM selftest to test moving the base gfn of a userspace memory region. Although the basic concept of moving memory regions is not x86 specific, the assumptions regarding large pages and MMIO shenanigans used to verify the correctness make this x86_64 only for the time being.

KVM: selftests: Add memory size parameter to the demand paging test

2020-03-16T16:57:02Z

Add an argument to allow the demand paging test to work on larger and smaller guest sizes. Signed-off-by: Ben Gardon [Rewrote parse_size() to simplify and provide user more flexibility as to how sizes are input. Also fixed size overflow assert.] Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

KVM: selftests: Create a demand paging test

2020-02-24T19:05:24Z

While userfaultfd, KVM's demand paging implementation, is not specific to KVM, having a benchmark for its performance will be useful for guiding performance improvements to KVM. As a first step towards creating a userfaultfd demand paging test, create a simple memory access test, based on dirty_log_test.

selftests, kvm: Replace manual MSR defs with common msr-index.h

2020-01-13T16:30:04Z

The kernel's version of msr-index.h was pulled wholesale into tools by commit 444e2ff34df8 ("tools arch x86: Grab a copy of the file containing the MSR numbers"), Use the common msr-index.h instead of manually redefining everything in a KVM-only header. Note, a few MSR-related definitions remain in processor.h because they are not covered by msr-index.h, including the awesomely named APIC_BASE_MSR, which refers to starting index of the x2APIC MSRs, not the actual MSR_IA32_APICBASE, which *is* defined by msr-index.h.
