[PATCH v4 0/8] Add an oversubscription test

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
