kernel/tools/testing/selftests/sgx/call.S, branch linux-6.2.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y2021-06-15T22:21:23Zselftests/sgx: Rename 'eenter' and 'sgx_call_vdso'2021-06-15T22:21:23ZJarkko Sakkinenjarkko@kernel.org2021-06-10T08:30:17Zurn:sha1:6a7171b8a0f8e961744d0c46fb7547662a3fca36
Rename symbols for better clarity:
* 'eenter' might be confused for directly calling ENCLU[EENTER]. It does
not. It calls into the VDSO, which actually has the EENTER instruction.
* 'sgx_call_vdso' is *only* used for entering the enclave. It's not some
generic SGX call into the VDSO.

selftests/x86: Add a selftest for SGX2020-11-18T17:04:05ZJarkko Sakkinenjarkko@kernel.org2020-11-12T22:01:31Zurn:sha1:2adcba79e69d4a4c0ac3bb86f466d8b5df301608
Add a selftest for SGX. It is a trivial test where a simple enclave
copies one 64-bit word of memory between two memory locations,
but ensures that all SGX hardware and software infrastructure is
functioning.
