Subject: drm/i915: fix i915_gem_object_wait_moving_fence
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 9362a07a0c5d6e566d614e988bc9c96102774a9d
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
All of CI is just failing with the following, which prevents loading of
the module:
i915 0000:03:00.0: [drm] *ERROR* Scratch setup failed
Best guess is that this comes from the pin_map() for the scratch page,
which does an i915_gem_object_wait_moving_fence() somewhere. It looks
like this now calls into dma_resv_wait_timeout() which can return the
remaining timeout, leading to the caller thinking this is an error.
v2(Lucas): handle ret == 0
Fixes: 1d7f5e6c5240 ("drm/i915: drop bo->moving dependency")
