Subject: [PATCH] drm/vc4: Use drm_malloc_ab to fix large rendering jobs.
|
|
|
|
If you exceeded the size that kmalloc would return, you'd get a dmesg
|
|
warning and a return from the job submit. We can handle much
|
|
allocations with vmalloc, and drm_malloc_ab makes that decision.
|
|
|
|
Fixes failure in piglit's scissor-many.
