| * drm: atomic helper: do not unreference error pointerLionel Landwerlin2016-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 562c5b4d8986 didn't quite fix the issue of dealing with an error pointer. We can't free/unref an error pointer so reset it to NULL. Many thanks to Dan Carpenter for pointing this out again.

| * drm/edid: Extract SADs properly from multiple audio data blocksVille Syrjälä2016-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SADs may span multiple CEA audio data blocks in the EDID. CEA-861-E says: "The order of the Data Blocks is not constrained. It is also possible to have more than one of a specific type of data block if necessary to include all of the descriptors needed to describe the sink’s capabilities." Each audio data block can carry up to 10 SADs, whereas the ELD SAD limit is 15 according to HDA 1.0a spec. So we should support at least two data blocks. And apparently some devices take a more liberal interpretation and stuff only one SAD per data block even when they would fit into one. So let's try to extract all the SADs we can fit into the ELD even when they span multiple data blocks. While at it, toss in a comment to explain the 13 byte monitor name string limit which confused me at first.

| * drm: introduce pipe color correction propertiesLionel Landwerlin2016-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current check doesn't handle the case where we don't steal an encoder, but keep it on the current connector.

| * drm/atomic: Handle encoder stealing from set_config better.Maarten Lankhorst2016-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of failing with -EINVAL when conflicting encoders are found, the legacy set_config will disable other connectors when encoders conflict. With the previous commit this becomes a lot easier to implement. set_config only adds connectors to the state that are modified, and because of the previous commit that calls add_affected_connectors only on set->crtc it means any connector not part of the modeset can be stolen from. We disable the connector in that case, and possibly the crtc if required. Atomic modeset itself still doesn't allow encoder stealing, the results would be too unpredictable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no need to have a separate function to get the crtc which is stolen, this can already be found when actually stealing the encoder. drm_for_each_connector already checks for connection_mutex, so use that macro now. Changes since v1: - Do not check for NULL crtc in connector_state, this may happen when a crtc is disabled and its encoder stolen. - Because of this, use connector->state->crtc instead of conn_state->crtc.

| * | 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).
