[PATCH v2 resend 4/5] drm/i915: add I915_PARAM_HAS_RESOURCE_STREAMER to i915_getparam

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This will let userspace know whether Resource Streamer is supported
in the kernel.

v2: Update I915_PARAM_HAS_RESOURCE_STREAMER so it's after
    I915_PARAM_HAS_GPU_RESET.
