Hi, all: This is a PING message, please help to review the LoongArch KVM selftests patches. Thanks Tianrui Zhao 在 2023/11/8 上午10:51, Tianrui Zhao 写道: > We add LoongArch support into KVM selftests and there are some KVM > test cases we have passed: > demand_paging_test > dirty_log_perf_test > dirty_log_test > guest_print_test > kvm_binary_stats_test > kvm_create_max_vcpus > kvm_page_table_test > memslot_modification_stress_test > memslot_perf_test > set_memory_region_test > > Changes for v4: > 1. Remove the based-on flag, as the LoongArch KVM patch series > have been accepted by Linux kernel, so this can be applied directly > in kernel. > > Changes for v3: > 1. Improve implementation of LoongArch VM page walk. > 2. Add exception handler for LoongArch. > 3. Add dirty_log_test, dirty_log_perf_test, guest_print_test > test cases for LoongArch. > 4. Add __ASSEMBLER__ macro to distinguish asm file and c file. > 5. Move ucall_arch_do_ucall to the header file and make it as > static inline to avoid function calls. > 6. Change the DEFAULT_GUEST_TEST_MEM base addr for LoongArch. > > Changes for v2: > 1. We should use ".balign 4096" to align the assemble code with 4K in > exception.S instead of "align 12". > 2. LoongArch only supports 3 or 4 levels page tables, so we remove the > hanlders for 2-levels page table. > 3. Remove the DEFAULT_LOONGARCH_GUEST_STACK_VADDR_MIN and use the common > DEFAULT_GUEST_STACK_VADDR_MIN to allocate stack memory in guest. > 4. Reorganize the test cases supported by LoongArch. > 5. Fix some code comments. > 6. Add kvm_binary_stats_test test case into LoongArch KVM selftests. > > changes for v1: > 1. Add kvm selftests header files for LoongArch. > 2. Add processor tests for LoongArch KVM. > 3. Add ucall tests for LoongArch KVM. > 4.
