Current, the dewake_scanline variable is defined as unsigned int, an unsigned int variable that is always greater than or equal to 0. when _intel_dsb_commit function is called by intel_dsb_commit function, the dewake_scanline variable may have an int value. So the dewake_scanline variable is necessary to defined as an int. Fixes: f83b94d2 ("drm/i915/dsb: Use DEwake to combat PkgC latency") Reported-by:

Apparently some BXT/GLK systems have DSI panels whose timings don't agree with the normal cpu transcoder hblank>=32 limitation. This is perhaps fine as there are no specific hblank/etc. limits listed for the BXT/GLK DSI transcoders. Move those checks out from the global intel_mode_valid() into into connector specific .mode_valid() hooks, skipping BXT/GLK DSI connectors. We'll leave the basic [hv]display/[hv]total checks in intel_mode_valid() as those seem like sensible upper limits regardless of the transcoder used.

Currently we are enabling selective fetch for all planes that are visible. This is suboptimal as we might be fetching for memory for planes that are not part of selective update. Fix this by adding proper handling for disabling plane selective fetch: If plane previously part of selective update is now not part of update: Add it into updated planes and let the plane configuration to disable selective fetch for it. v3: Checkpatch warnings fixed v2: - Add setting sel_fetch_area->y1/y2 to -1 - Remove setting again local sel_fetch_area variable Signed-off-by:

Jouni Högander authored
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:

drm_color_lut_extract() rounding was changed to follow the OpenGL int<->float conversion rules. Adjust intel_color_lut_pack() to match. Signed-off-by:
-
Ville Syrjälä authored
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:

{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: -
