Since multiple connectors may run intel_dp_aux_xfer conncurrently, a single global pm_qos does not suffice. (One connector may disable the dma-latency boost prematurely while the second is still depending on it.) Instead of a single global pm_qos, track the pm_qos request for each intel_dp. v2: Move the pm_qos setup/teardown to intel_dp_aux_init/fini Fixes: 9ee32fea ("drm/i915: irq-drive the dp aux communication") Signed-off-by:

No functional changes yet, this just adds definitions for all of the known DPCD registers used by Intel's HDR backlight interface. Since we'll only ever use this in i915, we just define them in intel_dp_aux_backlight.c Reviewed-by:

Since we're about to add support for a second type of backlight control interface over DP AUX (specifically, Intel's proprietary HDR backlight controls) let's rename all of the current backlight hooks we have for vesa to make it clear that they're specific to the VESA interface and not Intel's. v3: * Rebase Signed-off-by:

Instead of using intel_panel->backlight.level, have the caller provide us with the current panel backlight value. We'll need this for when we separate PWM-related backlight callbacks from other means of backlight control (like DPCD backlight controls), as the caller of each PWM callback will be responsible for converting the current brightness value to it's respective PWM level.

Lyude Paul authored
Since we're going to need to add a set of lower-level PWM backlight control hooks to be shared by normal backlight controls and HDR backlight controls in SDR mode, let's add a prefix to the external PWM backlight functions so that the difference between them and the high level PWM-only backlight functions is a bit more obvious. This introduces no functional changes. Signed-off-by:

Since we're about to start adding support for Intel's magic HDR backlight interface over DPCD, we need to ensure we're properly programming this field so that Intel specific sink services are exposed. Otherwise, 0x300-0x3ff will just read zeroes. We also take care not to reprogram the source OUI if it already matches what we expect. This is just to be careful so that we don't accidentally take the panel out of any backlight control modes we found it in. v2: * Add careful parameter to intel_edp_init_source_oui() to avoid re-writing the source OUI if it's already been set during driver initialization Signed-off-by:

The rc_model_size is specified in the DSC config, and the hardware programming should respect that instead of hard coding a value of 8192. Regardless, the rc_model_size in DSC config is currently hard coded to the same value, so this should have no impact, other than allowing the use of other sizes as needed.

The PPS is supposed to reflect the DSC config instead of hard coding the rc_model_size. Make it so.

This patch fixes the slice count computation algorithm for calculating the slice count based on Peak pixel rate and the max slice width allowed on the DSC engines. We need to ensure slice count > min slice count req as per DP spec based on peak pixel rate and that it is greater than min slice count based on the max slice width advertised by DPCD. So use max of these two. In the prev patch we were using min of these 2 causing it to violate the max slice width limitation causing a blank screen on 8K@60.

Since we try and estimate how long we require to update the registers to perform a plane update, it is of vital importance that we measure the distribution of plane updates to better guide our estimate. If we underestimate how long it takes to perform the plane update, we may slip into the next scanout frame causing a tear. If we overestimate, we may unnecessarily delay the update to the next frame, causing visible jitter. Replace the warning that we exceed some arbitrary threshold for the vblank update with a histogram for debugfs. v2: Add a per-crtc debugfs entry so that the information is easier to extract when testing individual CRTC, and so that it can be reset before a test. v3: Flip the graph on its side; creates space to label the time axis.
