2019-06-08drm/i915/dsi: Read back pclk set by GOP and use that as pclk (v3)Hans de Goede1-4/+18
The GOP sometimes initializes the pclk at a (slightly) different frequency then the pclk which we've calculated. This commit makes the DSI code read-back the pclk set by the GOP and if that is within a reasonable margin of the calculated pclk, uses that instead. This fixes the first modeset being a full modeset instead of a fast modeset on systems where the GOP pclk is different. Changes in v2: -Use intel_encoder_current_mode() to get the pclk setup by the GOP Changes in v3: -Back to the readback approach, skipping the dsi_pll.ctrl / .dev checks in intel_pipe_config_compare() when adjust is set leads to: [drm:pipe_config_err [i915]] *ERROR* mismatch in dsi_pll.ctrl (...)

2019-06-07drm/i915/sdvo: Implement proper HDMI audio support for SDVOVille Syrjälä2-11/+50
Our SDVO audio support is pretty bogus. We can't push audio over the SDVO bus, so trying to enable audio in the SDVO control register doesn't do anything. In fact it looks like the SDVO encoder will always mix in the audio coming over HDA, and there's no (at least documented) way to disable that from our side. So HDMI audio does work currently on gen4 but only by luck really. On gen3 it got broken by the referenced commit. And what has always been missing on every platform is the ELD. To pass the ELD to the audio driver we need to write it to magic buffer in the SDVO encoder hardware which then gets pulled out via HDA in the other end. Ie. pretty much the same thing we had for native HDMI before we started to just pass the ELD between the drivers. This sort of explains why we even have that silly hardware buffer with native HDMI. $ cat /proc/asound/card0/eld#1.0 -monitor_present 0 -eld_valid 0 +monitor_present 1 +eld_valid 1 +monitor_name LG TV +connection_type HDMI +... This also fixes our state readout since we can now query the SDVO encoder about the state of the "ELD valid" and "presence detect" bits. As mentioned those don't actually control whether audio gets sent over the HDMI cable, but it's the best we can do. And with the state checker appeased we can re-enable HDMI audio for gen3.

The AVI infoframe readout code currently issues a SDVO_CMD_GET_HBUF_TXRATE before SDVO_CMD_SET_HBUF_INDEX, which is not the correct order for these two operations. So far this wasn't a problem since we left the index pointing at the AVI infoframe buffer at the end of the modeset. However once we start to write to other buffers (namely ELD) that is no longer going to be true. Fix up the order so that we always read out the TX rate for the correct buffer.

2019-06-06drm/i915: Report an earlier wedged event when suspending the enginesChris Wilson1-1/+1
On i915_gem_load_power_context() we do care whether or not we succeed in completing the switch back to the kernel context (via idling the engines). Currently, we detect if an error occurs while we wait, but we do not report one if it occurred beforehand (and the status of the switch is undefined). Check the current terminally wedged status on entering the wait, and report it after flushing the requests, as if it had occurred during our own wait.

2019-06-06drm/i915: Skip context_barrier emission for unused contextsChris Wilson2-5/+29
The intent was to skip unused HW contexts by checking ce->state. However, this only works for execlists where the ppGTT pointers is stored inside the HW context. For gen7, the ppGTT is alongside the logical state and must be updated on all active engines but, crucially, only on active engines. As we need different checks, and to keep context_barrier_task() agnostic, pass in the predicate.

Unlike ICL, EHL's combo PHYs can support HBR3 data rates. Note that this just extends the upper limit; we will continue to honor the max data rate specified in the VBT in cases where it is lower than HBR3.

2019-06-05drm/i915/dsi: Use a fuzzy check for burst mode clock checkHans de Goede3-1/+13
Prior to this commit we fail to init the DSI panel on the GPD MicroPC: https://www.indiegogo.com/projects/gpd-micropc-6-inch-handheld-industry-laptop#/ The problem is intel_dsi_vbt_init() failing with the following error: *ERROR* Burst mode freq is less than computed The pclk in the VBT panel modeline is 70000, together with 24 bpp and 4 lines this results in a bitrate value of 70000 * 24 / 4 = 420000. But the target_burst_mode_freq in the VBT is 418000. This commit works around this problem by adding an intel_fuzzy_clock_check when target_burst_mode_freq < bitrate and setting target_burst_mode_freq to bitrate when that checks succeeds, fixing the panel not working.
