Subject: [PATCH v3 0/8] Add an oversubscription test
Date: Fri, 6 Aug 2021 03:16:56 +0300 [thread overview]
Message-ID: <20210806001704.667889-1-jarkko@kernel.org> (raw)
The goal of these patches is to add a test case for a SGX reserved
memory oversubscription, i.e. make sure that the page reclaimer and
and the page fault handler are working correctly.
Change Log
==========
v3:
* Reorganized the patch set into smaller pieces, and refactored the code so that
the test enclave can be created inside each test case. Added a new test case
unclobbered_vdso_oversubscribed that creates a large enough heap to
fill all of the available SGX reserved memory (EPC).
Jarkko Sakkinen (8):
x86/sgx: Add /sys/kernel/debug/x86/sgx_total_mem
selftests/sgx: Assign source for each segment
selftests/sgx: Make data measurement for an enclave segment optional
selftests/sgx: Create a heap for the test enclave
selftests/sgx: Dump segments and /proc/self/maps only on failure
selftests/sgx: Encpsulate the test enclave creation
selftests/sgx: Move setup_test_encl() to each TEST_F()
selftests/sgx: Add a new kselftest: unclobbered_vdso_oversubscribed
