Hi,
I look at the patches. Here Is my questions:
- what is the strategy for merging? I would agree that we should merge the non-virtualization and virtualization separately.
Agree on the strategy of separating virt and non-virt parts. This patchset is only for non-virt(native) part.
- where could I find the testcsases along with your patches.
This patchset includes the selftest for sgx. So far we only test it by sgx selftest.
After applying this patchset, switch to openeuler-kernel/tools/testing/selftests/sgx [root@localhost sgx]# ./test_sgx
- why 74faeee06db8 "x86/mm: Signal SIGSEGV with PF_SGX" is skipped?
Good catch up! Please also include this one. Thanks.
Regards
Bamvor
Thanks, --Jun
