Currently selective fetch configuration for planes is implemented in psr code. More suitable place for this code is where everything else is configured for planes -> move it into skl_universal_plane.c and intel_cursor.c. This also allows us to drop hooks for cursor handling. v3: Checkpatch warnings fixed v2: Removed setting sel_fetch_area->y1/y2 as -1 Signed-off-by:

The current implementation of change_lut_val_precision() is just a convoluted way of shifting by 8. Implement the proper rounding by just using drm_color_lut_extract() and intel_color_lut_pack() like everyone else does. And as the uapi can't handle >=1.0 values but the hardware can we need to clamp the results appropriately in the readout path. Signed-off-by:

The current implementation of drm_color_lut_extract() generates weird results. Eg. if we go through all the values for 16->8bpc conversion we see the following pattern: in out (count) 0 - 7f -> 0 (128) 80 - 17f -> 1 (256) 180 - 27f -> 2 (256) 280 - 37f -> 3 (256) ... fb80 - fc7f -> fc (256) fc80 - fd7f -> fd (256) fd80 - fe7f -> fe (256) fe80 - ffff -> ff (384) So less values map to 0 and more values map 0xff, which doesn't seem particularly great. To get just the same number of input values to map to the same output values we'd just need to drop the rounding entrirely. But perhaps a better idea would be to follow the OpenGL int<->float conversion rules, in which case we get the following results: in out (count) 0 - 80 -> 0 (129) 81 - 181 -> 1 (257) 182 - 282 -> 2 (257) 283 - 383 -> 3 (257) ... fc7c - fd7c -> fc (257) fd7d - fe7d -> fd (257) fe7e - ff7e -> fe (257) ff7f - ffff -> ff (129) Note that since the divisor is constant the compiler is able to optimize away the integer division in most cases. The only exception is the _ULL() case on 32bit architectures since that gets emitted as inline asm via do_div() and thus the compiler doesn't get to optimize it. Signed-off-by:

There's no real reason why we'd need a full modeset for audio changes. So let's allow audio to be toggled during fastset. In case the ELD changes while has_audio isn't changing state we force both audio disable and enable so the new ELD gets propagated to the audio driver. Reviewed-by:

We used to call intel_pre_plane_updates() for any pipe going through a modeset whether the pipe was previously enabled or not.

{planes,vrr}_{enabling,disabling}() are supposed to indicate whether the specific hardware feature is supposed to be enabling or disabling. That can only makes sense if the pipe is active overall. So check for that before we go poking at the hardware. I think we're semi-safe currently on due to: - intel_pre_plane_update() doesn't get called when the pipe was not-active prior to the commit, but this is actually a bug. This saves vrr_disabling(), and vrr_enabling() is called from deeper down where we have already checked hw.active. - active_planes mirrors the crtc's hw.active Reviewed-by: -

To properly deal with GPIOs used in MIPI panel sequences a temporary GPIO lookup will be used. Since there can only be 1 GPIO lookup table for the "0000:00:02.0" device this will not work if the GPIO lookup table used by intel_dsi_vbt_gpio_init() is still registered. After getting the "backlight" and "panel" GPIOs the lookup table registered by intel_dsi_vbt_gpio_init() is no longer necessary, remove it so that another temporary lookup-table for the "0000:00:02.0" device can be added.
