This is set of fixes and new unit tests that I developed for the
KVM unit tests.
I also did some work to separate the SVM code into a minimal
support library so that you could use it from an arbitrary test.
V2:
- addressed review feedback, and futher cleaned up the svm tests
set to use less global variables
(the patches are large, but each changes one thing all over the tests, so hopefully not hard to review).
Best regards,
Maxim Levitsky
Maxim Levitsky (27):
x86: replace irq_{enable|disable}() with sti()/cli()
x86: introduce sti_nop() and sti_nop_cli()
x86: add few helper functions for apic local timer
svm: remove nop after stgi/clgi
svm: make svm_intr_intercept_mix_if/gif test a bit more robust
svm: use apic_start_timer/apic_stop_timer instead of open coding it
x86: Add test for #SMI during interrupt window
x86: Add a simple test for SYSENTER instruction.
svm: add simple nested shutdown test.
SVM: add two tests for exitintinto on exception
lib: Add random number generator
x86: add IPI stress test
svm: remove get_npt_pte extern
svm: move svm spec definitions to lib/x86/svm.h
svm: move some svm support functions into lib/x86/svm_lib.h
svm: move setup_svm() to svm_lib.c
svm: correctly skip if NPT not supported
svm: move vmcb_ident to svm_lib.c
svm: rewerite vm entry macros
svm: move v2 tests run into test_run
svm: cleanup the default_prepare
svm: introduce svm_vcpu
svm: introduce struct svm_test_context
svm: use svm_test_context in v2 tests
svm: move nested vcpu to test context
svm: move test_guest_func to test context
x86: ipi_stress: add optional SVM support
