2023-12-04drm/i915/display: Split i915 specific code away from intel_fb.cJouni Högander4-63/+127
We are preparing for Xe driver. Backing object implementation is differing between i915 and Xe. Split i915 specific code into separate source file built only for i915. v9: - Use ERR_CAST v8: - return original error code from intel_fb_bo_lookup_valid_bo on failure v7: - drop #include <drm/drm_plane.h> - s/user_mode_cmd/mode_cmd/ - Use passed i915 pointer instead of to_i915(obj->base.dev) v6: Add missing intel_fb_bo.[ch] v5: - Keep drm_any_plane_has_format check in intel_fb.c - Use mode_cmd instead of user_mode_cmd for intel_fb_bo_lookup_valid_bo v4: Move drm_any_plane_has_format check into intel_fb_bo.c v3: Fix failure handling in intel_framebuffer_init v2: Couple of fixes to error value handling Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231203114840.841311-5-jouni.hogander@intel.com

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.

2023-11-23drm: Fix color LUT roundingVille Syrjälä1-11/+8
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.

Follow the hsw+ approach toggle the audio presence detect when we set up the ELD, instead of doing it when turning the port on/off. This will facilitate audio enable/disable to happen during fastsets instead of requiring a full modeset.

Put a wrapper around the intel_audio_codec_{enable,disable}() calls in the g4x+ DP/HDMI code. We shall move the presence detect enable/disable into the wrappers later.

2023-11-23drm/i915: Call intel_pre_plane_updates() also for pipes getting enabledVille Syrjälä1-1/+2
We used to call intel_pre_plane_updates() for any pipe going through a modeset whether the pipe was previously enabled or not. This in fact needed to apply all the necessary clock gating workarounds/etc. Restore the correct behaviour.

2023-11-23drm/i915: Check pipe active state in {planes,vrr}_{enabling,disabling}()Ville Syrjälä1-0/+12
{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: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231121054324.9988-2-ville.syrjala@linux.intel.com
