[igt-dev] [PATCH i-g-t] tests/xe_drm_fdinfo: Add tests to read and verify fdinfo
Tejas Upadhyay

Tue Sep 5 06:38:33 UTC 2023
This test verifies fdinfo published by xe KMD with
following tests :
@basic
@drm-total-residents
@drm-shared
@drm-active
TODO : drm-purgeable test is not possbile as we consider objects in
system memory to be purgeable but current xe KMD does not allow
BOs to be created in system memory (instead KMD creates it in
XE_PL_TT which is VRAM backed system memory).
