At the end of the function we expect "status" to be zero, but it's either -EINVAL or uninitialized. Fixes: 788bf83d ('drm/amdkfd: Add wave control operation to debugger') Signed-off-by:

This pull request covers what's left for 4.6. Notably, it includes a significant 3D performance improvement and a fix to HDMI hotplug detection for the Pi2/3. * tag 'drm-vc4-next-2016-03-14' of github.com:anholt/linux: drm/vc4: Recognize a more specific compatible string for V3D. dt-bindings: Add binding docs for V3D. drm/vc4: Return -EFAULT on copy_from_user() failure drm/vc4: Respect GPIO_ACTIVE_LOW on HDMI HPD if set in the devicetree. drm/vc4: Let gpiolib know that we're OK with sleeping for HPD. drm/vc4: improve throughput by pipelining binning and rendering jobs

The Raspberry Pi Foundation's firmware updates are shipping device trees using the old string, so we'll keep recognizing that as this rev of V3D. Still, we should use a more specific name in the upstream DT to clarify which board is being supported, in case we do other revs of V3D in the future. Signed-off-by:

This allows to instanciate drivers that use the same logic as gk20a with different parameters. Add a constructor function to allow other chips that inherit from this clock to easily initialize its members Signed-off-by:

This class supports a WFI method (0x0078) that's not present on the KeplerChannelGpfifoA class. The binary driver exposes both classes on these GPUs for some reason, though there doesn't appear to be any difference in the setup that's done for each (ie. even if you allocate GpfifoA, the WFI method will still work). We shall just expose GpfifoB, as I don't see a good reason to report the presence of both. Signed-off-by: -
