Introduce an xarray based version array (VA) structure: struct sgx_va.
The use of sgx_va can be later on extended to the following use cases:
- A global VA for reclaimed SECS pages.
- A global VA for reclaimed VA pages.
Testing done while developing the patch:
- With NUC7PJYH: https://www.intel.com/content/www/us/en/products/boards-k...
- seq 10000 | xargs -I {} -P10000 ./test_sgx > /dev/null
- The EPC size was set from BIOS to 32 MB.
Jarkko Sakkinen (3):
x86/sgx: Move struct sgx_va_page creation to sgx_alloc_va_page()
x86/sgx: Add a version array (VA) structure
x86/sgx: Use sgx_va for the enclave's version array
