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.
