[igt-dev] [PATCH i-g-t] tests/kms_lease: Terminate lease fd before subtests execution

Mohammed Thasleem mohammed.thasleem at intel.com
Mon Aug 14 16:14:12 UTC 2023


Failures happen at drmModeSetCursor and prepare_crtc_master or
prepare_crtc_lease which exit tests without termination of lease fd
which resulting in resource busy for sub-sequence execution, when
new lessor request for lease.

Terminate the lease fd when any assert happen with out termination
of lease fd and on any drmModeSetCrtc or drmModeGetCrtc exit.
Terminate lease fd on every display dependent subtests execution.

v2: -Separated prepare crtc for master and lease.
    -Removed lease_t from all sub-tests.
v3: Updated commit message.
v4: Avoid duplicating prepare_crtc.
