This is essentially v2 of the previous attempt[*], sans the fix for exectuable stack warnings (now fixed for all architectures), plus fixes for nVMX testcases related to 64-bit hosts (these *just* got posted, but it's not like anyone else is reviewing KUT x86 changes these days, so I don't see any point in waiting). There's one non-x86 change to fix a bug in processing "check" entries in unittests.cfg files. The majority of the x86 changes revolve around nSVM, PMU, and emulator tests.

Fix a bug in runtime.bash that caused it to mishandle "check" strings with multiple entries, e.g. a test that depends on multiple module params - Make the PMU tests depend on vPMU support being enabled in KVM - Fix PMU's forced emulation test on CPUs with full-width writes - Add a PMU testcase for measuring TSX transactional cycles - Nested SVM testcase for virtual NMIs - Move a pile of code to ASM_TRY() and "safe" helpers - Set up the guest stack in the LBRV tests so that the tests don't fail if the compiler decides to generate function calls in guest code - Ignore the "mispredict" flag in nSVM's LBRV tests to fix false failures - Clean up usage of helpers that disable interrupts, e.g. stop inserting unnecessary nops - Add helpers to dedup code for programming the APIC timer - Fix a variety of bugs in nVMX testcases related to being a 64-bit host ---------------------------------------------------------------- Like Xu (2): x86/pmu: Add Intel Guest Transactional (commited) cycles testcase x86/pmu: Wrap the written counter value with gp_counter_width Mathias Krause (15): x86: Drop types.h x86: Use symbolic names in exception_mnemonic() x86: Add vendor specific exception vectors x86/cet: Use symbolic name for #CP x86/access: Use 'bool' type as defined via libcflat.h x86/run_in_user: Preserve exception handler x86/run_in_user: Relax register constraints of inline asm x86/run_in_user: Reload SS after successful return x86/fault_test: Preserve exception handler x86/emulator64: Relax register constraints for usr_gs_mov() x86/emulator64: Switch test_sreg() to ASM_TRY() x86/emulator64: Add non-null selector test x86/emulator64: Switch test_jmp_noncanonical() to ASM_TRY() x86/emulator64: Switch test_mmx_movq_mf() to ASM_TRY() x86/emulator64: Test non-canonical memory access exceptions Maxim Levitsky (8): 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 x86: nSVM: Remove nop after stgi/clgi x86: nSVM: make svm_intr_intercept_mix_if/gif test a bit more robust x86: nSVM: use apic_start_timer/apic_stop_timer instead of open coding it x86: nSVM: Add nested shutdown interception test x86: nSVM: Remove defunct get_npt_pte() declaration Santosh Shukla (1): x86: nSVM: Add support for VNMI test Sean Christopherson (21): nSVM: Add helper to report fatal errors in guest x86: Add macros to wrap ASM_TRY() for single instructions x86: Convert inputs-only "safe" instruction helpers to asm_safe() x86: Add macros to wrap ASM_TRY() for single instructions with output(s) x86: Move invpcid_safe() to processor.h and convert to asm_safe() x86: Move XSETBV and XGETBV "safe" helpers to processor.h x86: nSVM: Set up a guest stack in LBRV tests lib: Expose a subset of VMX's assertion macros x86: Add defines for the various LBR record bit definitions x86: nSVM: Ignore mispredict bit in LBR records x86: nSVM: Replace check_dbgctl() with TEST_EXPECT_EQ() in LBRV test x86: nSVM: Print out RIP and LBRs from VMCB if LBRV guest test fails runtime: Convert "check" from string to array so that iterating works x86/pmu: Make PMU testcases dependent on vPMU being enabled in KVM nVMX: Test CR4.PCIDE can be set for 64-bit host iff PCID is supported nVMX: Assert CR4.PAE is set when testing 64-bit host nVMX: Assert that the test is configured for 64-bit mode nVMX: Rename vmlaunch_succeeds() to vmlaunch() nVMX: Shuffle test_host_addr_size() tests to "restore" CR4 and RIP nVMX: Drop testcase that falsely claims to verify vmcs.HOST_RIP[63:32] nVMX: Fix the noncanonical HOST_RIP testcase lib/util.h | 31 ++++ lib/x86/apic.c | 38 ++++ lib/x86/apic.h | 6 + lib/x86/desc.c | 43 +++-- lib/x86/desc.h | 48 ++++++ lib/x86/fault_test.c | 4 +- lib/x86/msr.h | 11 ++ lib/x86/processor.h | 137 +++++++++------ lib/x86/smp.c | 2 +- lib/x86/usermode.c | 38 ++-- scripts/runtime.bash | 1 + x86/access.c | 11 +- x86/apic.c | 6 +- x86/asyncpf.c | 6 +- x86/cet.c | 2 +- x86/cmpxchg8b.c | 1 -
