KVM: arm64: selftests: Fix multiple versions of GIC creation

2022-10-10T08:41:39Z

Commit 98f94ce42ac6 ("KVM: selftests: Move KVM_CREATE_DEVICE_TEST code to separate helper") wrongly converted a "real" GIC device creation to __kvm_test_create_device() and caused the test failure on my D05 (which supports v2 emulation). Fix it.

KVM: selftests: Update top-of-file comment in psci_test

2022-09-28T15:47:59Z

Fix the comment to accurately describe the test and recently added SYSTEM_SUSPEND test case. What was once psci_cpu_on_test was renamed and extended to squeeze in a test case for PSCI SYSTEM_SUSPEND. Nonetheless, the author of those changes (whoever they may be...) failed to update the file comment to reflect what had changed.

KVM: arm64: selftests: Add a test case for KVM_GUESTDBG_SINGLESTEP

2022-09-19T09:48:53Z

Add a test case for KVM_GUESTDBG_SINGLESTEP to the debug-exceptions test. The test enables single-step execution from userspace, and check if the exit to userspace occurs for each instruction that is stepped. Set the default number of the test iterations to a number of iterations sufficient to always reproduce the problem that the previous patch fixes on an Ampere Altra machine.

KVM: arm64: selftests: Refactor debug-exceptions to make it amenable to new test cases

2022-09-19T09:48:53Z

Split up the current test into a helper, but leave the debug version checking in main(), to make it convenient to add a new debug exception test case in a subsequent patch.

KVM: selftests: Add test for AArch32 ID registers

2022-09-14T10:36:16Z

Add a test to assert that KVM handles the AArch64 views of the AArch32 ID registers as RAZ/WI (writable only from userspace). For registers that were already hidden or unallocated, expect RAZ + invariant behavior.

Merge tag 'kvmarm-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2022-08-01T07:24:12Z

KVM/arm64 updates for 5.20: - Unwinder implementations for both nVHE modes (classic and protected), complete with an overflow stack - Rework of the sysreg access from userspace, with a complete rewrite of the vgic-v3 view to allign with the rest of the infrastructure - Disagregation of the vcpu flags in separate sets to better track their use model. - A fix for the GICv2-on-v3 selftest - A small set of cosmetic fixes

KVM: arm64: selftests: Add support for GICv2 on v3

2022-07-15T10:01:00Z

The current vgic_init test wrongly assumes that the host cannot multiple versions of the GIC architecture, while v2 emulation on v3 has almost always been supported (it was supported before the standalone v3 emulation). Tweak the test to support multiple GIC incarnations.

KVM: selftests: Fix filename reporting in guest asserts

2022-07-14T01:14:08Z

Fix filename reporting in guest asserts by ensuring the GUEST_ASSERT macro records __FILE__ and substituting REPORT_GUEST_ASSERT for many repetitive calls to TEST_FAIL. Previously filename was reported by using __FILE__ directly in the selftest, wrongly assuming it would always be the same as where the assertion failed.
