Subject: [PATCH v2 0/4] Swap and fault all the pages of the test enclave binary
Date: Thu, 29 Jul 2021 01:51:36 +0300	[thread overview]
Message-ID: <20210728225140.248408-1-jarkko@kernel.org> (raw)

Create a heap for the test enclave, which has the same size as all
available Enclave Page Cache (EPC) pages in the system. This will guarantee
that all test_encl.elf pages *and* SGX Enclave Control Structure (SECS)
have been swapped out by the page reclaimer during the load time. Actually,
this adds a bit more stress than that since part of the EPC gets reserved
for the Version Array (VA) pages.

For each test, the page fault handler gets triggered in two occasions:

- When SGX_IOC_ENCLAVE_INIT is performed, SECS gets swapped in by the
  page fault handler.
- During the execution, each page that is referenced gets swapped in
  by the page fault handler.
