2021-07-15KVM: selftests: Address extra memslot parameters in vm_vaddr_allocRicardo Koller1-1/+1
Commit a75a895e6457 ("KVM: selftests: Unconditionally use memslot 0 for vaddr allocations") removed the memslot parameters from vm_vaddr_alloc. It addressed all callers except one under lib/aarch64/, due to a race with commit e3db7579ef35 ("KVM: selftests: Add exception handling support for aarch64") Fix the vm_vaddr_alloc call in lib/aarch64/processor.c.

2021-06-24KVM: selftests: Add wrapper to allocate page table pageSean Christopherson1-13/+6
Add a helper to allocate a page for use in constructing the guest's page tables. All architectures have identical address and memslot requirements (which appear to be arbitrary anyways).

Drop the memslot param(s) from vm_vaddr_alloc() now that all callers directly specific '0' as the memslot. Drop the memslot param from virt_pgd_alloc() as well since vm_vaddr_alloc() is its only user. I.e. shove the hardcoded '0' down to the vm_phy_pages_alloc() calls. No functional change intended.

2021-06-14KVM: selftests: Add exception handling support for aarch64Ricardo Koller2-0/+223
Add the infrastructure needed to enable exception handling in aarch64 selftests. The exception handling defaults to an unhandled-exception handler which aborts the test, just like x86. These handlers can be overridden by calling vm_install_exception_handler(vector) or vm_install_sync_handler(vector, ec). The unhandled exception reporting from the guest is done using the ucall type introduced in a previous commit, UCALL_UNHANDLED. The exception handling code is inspired on kvm-unit-tests.

2020-03-16KVM: selftests: Rework debug message printingAndrew Jones1-1/+1
There were a few problems with the way we output "debug" messages. The first is that we used DEBUG() which is defined when NDEBUG is not defined, but NDEBUG will never be defined for kselftests because it relies too much on assert(). The next is that most of the DEBUG() messages were actually "info" messages, which users may want to turn off if they just want a silent test that either completes or asserts. Finally, a debug message output from a library function, and thus for all tests, was annoying when its information wasn't interesting for a test. Rework these messages so debug messages only output when DEBUG is defined and info messages output unless QUIET is defined. Also name the functions pr_debug and pr_info and make sure that when they're disabled we eat all the inputs. The later avoids unused variable warnings when the variables were only defined for the purpose of printing.

2020-03-16KVM: selftests: Add support for vcpu_args_set to aarch64 and s390xBen Gardon1-0/+35
Currently vcpu_args_set is only implemented for x86. This makes writing tests with multiple vCPUs difficult as each guest vCPU must either a.) do the same thing or b.) derive some kind of unique token from it's registers or the architecture. To simplify the process of writing tests with multiple vCPUs for s390 and aarch64, add set args functions for those architectures.

2019-09-24KVM: selftests: Introduce VM_MODE_PXXV48_4KPeter Xu1-0/+3
The naming VM_MODE_P52V48_4K is explicit but unclear when used on x86_64 machines, because x86_64 machines are having various physical address width rather than some static values. Here's some examples: - Intel Xeon E3-1220: 36 bits - Intel Core i7-8650: 39 bits - AMD EPYC 7251: 48 bits All of them are using 48 bits linear address width but with totally different physical address width (and most of the old machines should be less than 52 bits). Let's create a new guest mode called VM_MODE_PXXV48_4K for current x86_64 tests and make it as the default to replace the old naming of VM_MODE_P52V48_4K because it shows more clearly that the PA width is not really a constant. Meanwhile we also stop assuming all the x86 machines are having 52 bits PA width but instead we fetch the real vm->pa_bits from CPUID 0x80000008 during runtime. We currently make this exclusively used by x86_64 but no other arch. As a slight touch up, moving DEBUG macro from dirty_log_test.c to kvm_util.h so lib can use it too.

2019-08-02KVM: selftests: Split ucall.c into architecture specific filesThomas Huth1-0/+112
The way we exit from a guest to userspace is very specific to the architecture: On x86, we use PIO, on aarch64 we are using MMIO and on s390x we're going to use an instruction instead. The possibility to select a type via the ucall_type_t enum is currently also completely unused, so the code in ucall.c currently looks more complex than required. Let's split this up into architecture specific ucall.c files instead, so we can get rid of the #ifdefs and the unnecessary ucall_type_t handling.
