I sent an earlier version of this patch by mistake (it includes indentation errors) - I apologize for that, will fix this in v3 later. Sorry for the noise. Krzysztof On 2025-01-28 at 12:53:44 +, Krzysztof Karas wrote: > There is an error path in igt_ppgtt_alloc(), which leads to ww > object b

[PATCH v2] drm/i915/selftests: avoid using uninitialized context

2025-01-28 Thread Krzysztof Karas
There is an error path in igt_ppgtt_alloc(), which leads to ww object being passed down to i915_gem_ww_ctx_fini() without initialization. Correct that by putting ppgtt->vm and returning early. Fixes: 480ae79537b2 ("drm/i915/selftests: Prepare gtt tests for obj->mm.lock removal") Signed-off-by: Kr
