[PATCH 00/10] KVM: selftests: Add KVM_SET_MEMORY_REGION tests
From: Sean Christopherson
Date: Fri Apr 10 2020 - 19:17:14 EST
This is v2-ish of my series to add a "delete" testcase[1], and v5.1 of
Wainer's series to add a "max" testcase[2].
I've only tested on x86_64. I fudged compile testing on !x86_64 by
inverting the ifdefs, e.g. to squish unused var warnings, but by no means
is the code actually tested on other architectures.
I kept Andrew's review for the "max" test. Other than the 1MB->2MB
change (see below), it was basically a straight copy-paste of code.
v1->v2 of delete:
- Drop patch to expose primary memslot. [Peter]
- Add explicit synchronization to MOVE and DELETE tests. [Peter]
- Use list.h instead of open coding linked lists. [Peter]
- Clean up the code and separate the testcases into separate functions.
- Expand GUEST_ASSERT() to allow passing a value back to the host for
printing.
- Move to common KVM, with ifdefs to hide the x86_64-only stuff (which
is a lot at this point).
- Do KVM_SET_NR_MMU_PAGES in the "zero" testcase to get less obscure
behavior for KVM_RUN. [Christian]
v5.1 of max:
- Fix a whitespace issue in vm_get_fd(). [checkpatch]
- Move the code to set_memory_region_test. The only _intended_
functional change is to create 2MB regions instead of 1MB regions.
The only motivation for doing so was to reuse an existing define in
set_memory_region_test.
