Subject: [PATCH i-g-t 0/1] tests/xe_vm: Add oversubscribe concurrent bind stress test
Date: Wed, 18 Feb 2026 16:44:16 +0000	[thread overview]
Message-ID: <20260218164417.856114-1-sobin.thomas@intel.com> (raw)

Add an xe_vm subtest that oversubscribes VRAM and issues
concurrent binds into a single VM (scratch-page mode) to
reproduce the dma-resv/bind race found under memory pressure.
Prior coverage lacked any case that combined multi-process bind
pressure with VRAM oversubscription, so bind/submit could
panic (NULL deref in xe_pt_stage_bind) instead of failing cleanly.
The new test expects successful completion or ENOMEM/EDEADLK.
