* drm/amdkfd: uninitialized variable in dbgdev_wave_control_set_registers()Dan Carpenter2016-03-15
| | | | | | | | | At the end of the function we expect "status" to be zero, but it's either -EINVAL or uninitialized. Fixes: 788bf83db301 ('drm/amdkfd: Add wave control operation to debugger') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 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
| * drm/vc4: Recognize a more specific compatible string for V3D.Eric Anholt2016-03-13
| | | | | | | | | | | | | | | | | | | | | | 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.

| * drm/vc4: Return -EFAULT on copy_from_user() failureDan Carpenter2016-03-13
| | | | | | | | | | | | | | | | | | | | | | The copy_from_user() function returns the number of bytes not copied but we want to return a negative error code.

| * drm/vc4: Respect GPIO_ACTIVE_LOW on HDMI HPD if set in the devicetree.Eric Anholt2016-03-13
| | | | | | | | | | | | | | | | | | | | The original Raspberry Pi had the GPIO active high, but the later models are active low. The DT GPIO bindings allow specifying the active flag, except that it doesn't get propagated to the gpiodesc, so you have to handle it yourself.

| * drm/vc4: improve throughput by pipelining binning and rendering jobsVarad Gautam2016-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware provides us with separate threads for binning and rendering, and the existing model waits for them both to complete before submitting the next job. Splitting the binning and rendering submissions reduces idle time and gives us approx 20-30% speedup with some x11perf tests such as -line10 and -tilerect1. Improves openarena performance by 1.01897% +/- 0.247857% (n=16). Thanks to anholt for suggesting this. v2: Rebase on the spurious resets fix (change by anholt).

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).
