Patches 1 fixes a goof in kvm/queue and should be squashed. I would really, really, really like to get this queued up sooner than later, or maybe just thrown into a separate selftests-specific branch that folks can develop against. Rebasing is tedious, frustrating, and time consuming. And spoiler alert, there's another 42 x86-centric patches inbound that builds on this series to clean up CPUID related crud... The primary theme is to stop treating tests like second class citizens. Stop hiding vcpu, kvm_vm, etc... There's no sensitive data/constructs, and the encapsulation has led to really, really bad and difficult to maintain code. E.g. having to pass around the VM just to call a vCPU ioctl(), arbitrary non-zero vCPU IDs, tests having to care about the vCPU ID in the first place, etc... The other theme in the rework is to deduplicate code and try to set us up for success in the future. E.g. provide macros/helpers instead of spamming CTRL-C => CTRL-V (see the -1k LoC), structure the VM creation APIs to build on one another, etc... The absurd patch count (as opposed to just ridiculous) is due to converting each test away from using hardcoded vCPU IDs in a separate patch. The vast majority of those patches probably aren't worth reviewing in depth, the changes are mostly mechanical in nature. However, _running_ non-x86 tests (or tests that have unique non-x86 behavior) would be extremely valuable. All patches have been compile tested on x86, arm, risc-v, and s390, but I've only run the tests on x86. Based on my track record for the x86+common tests, I will be very, very surprised if I didn't break any of the non-x86 tests, e.g. pthread_create()'s 'void *' param tripped me up multiple times. I have not run x86's amx_test due to lack of hardware. I also haven't run sev_migration; something is wonky in either the upstream support for INIT_EX or in our test machines and I can't get SEV to initialize. v2: - Drop the forced -Werror patch. [Vitaly] - Add TEST_REQUIRE to reduce KSFT_SKIP boilerplate. - Rebase to kvm/queue, commit 55371f1d0c01. - Clean up even more bad copy+paste code (x86 was hiding a lot of crud). - Assert that the input to an ioctl() is (likely) the correct struct. v1: https://lore.kernel.org/all/20220504224914.1654036-1-seanjc@google.com Sean Christopherson (144): KVM: Fix references to non-existent
