2024-08-16drm/i915/lspcon: convert to struct intel_displayJani Nikula
Going forward, struct intel_display shall replace struct drm_i915_private as the main display device data pointer type. Convert intel_lspcon.[ch] to struct intel_display.

2023-10-04drm/i915/display/lspcon: Increase LSPCON mode settle timeoutNiko Tsirakis
This is to eliminate all cases of "*ERROR* LSPCON mode hasn't settled", followed by link training errors. Intel engineers recommended increasing this timeout and that does resolve the issue. On some CometLake-based device designs the Parade PS175 takes more than 400ms to settle in PCON mode. 100 reboot trials on one device resulted in a median settle time of 440ms and a maximum of 444ms. Even after increasing the timeout to 500ms, 2% of devices still had this error. So this increases the timeout to 800ms.

2022-11-11drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula
Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place. Also some places actually needed i915_irq.h too.

2022-04-25drm/display: Move HDMI helpers into display-helper moduleThomas Zimmermann
Move DRM's HMDI helpers into the display/ subdirectoy and add it to DRM's display helpers. Update all affected drivers. No functional changes. The HDMI helpers were implemented in the EDID and connector code, but are actually unrelated. With the move to the display-helper library, we can remove the dependency on drm_edid.{c,h} in some driver's HDMI source files. Several of the HDMI helpers remain in EDID code because both share parts of their implementation internally. With better refractoring of the EDID code, those HDMI helpers could be moved into the display-helper library as well. v3: * fix Kconfig dependencies (Javier) v2: * reduce HDMI helpers to avoid exporting functions (Jani) * fix include statements (Jani, Javier) * update Kconfig symbols Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-8-tzimmermann@suse.de

2020-10-01drm/i915: Init lspcon after HPD in intel_dp_detect()Kai-Heng Feng
On HP 800 G4 DM, if HDMI cable isn't plugged before boot, the HDMI port becomes useless and never responds to cable hotplugging: [ 3.031904] [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon [ 3.031945] [drm:intel_ddi_init [i915]] *ERROR* LSPCON init failed on port D Seems like the lspcon chip on the system only gets powered after the cable is plugged. Consilidate lspcon_init() into lspcon_resume() to dynamically init lspcon chip, and make HDMI port work. v6: - Rebase on latest for-linux-next. v5: - Consolidate lspcon_resume() with lspcon_init(). - Move more logic into lspcon code. v4: - Trust VBT in intel_infoframe_init(). - Init lspcon in intel_dp_detect(). v3: - Make sure it's handled under long HPD case. v2: - Move lspcon_init() inside of intel_dp_hpd_pulse().

2020-08-31drm/i915/dp: Extract drm_dp_read_dpcd_caps()Lyude Paul
Since DP 1.3, it's been possible for DP receivers to specify an additional set of DPCD capabilities, which can take precedence over the capabilities reported at DP_DPCD_REV. Basically any device supporting DP is going to need to read these in an identical manner, in particular nouveau, so let's go ahead and just move this code out of i915 into a shared DRM DP helper that we can use in other drivers. v2: * Remove redundant dpcd[DP_DPCD_REV] == 0 check * Fix drm_dp_dpcd_read() ret checks Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Sean Paul <sean@poorly.run> Link: https://patchwork.freedesktop.org/patch/msgid/20200826182456.322681-20-lyude@redhat.com
2020-07-02drm/i915/display: prefer dig_port to reference intel_digital_portLucas De Marchi
We have a mix of dport, intel_dport, intel_dig_port and dig_port to reference a intel_digital_port struct. Numbers are around 5 intel_dport 36 dport 479 intel_dig_port 352 dig_port Since we already removed the intel_ prefix from most of our other structs, do the same here and prefer dig_port. v2: rename everything in i915, not just a few display sources and reword commit message (from Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200701045054.23357-1-lucas.demarchi@intel.com
2020-05-14drm/i915: Fix enabled infoframe states of lspconGwan-gyeong Mun
Compared to implementation of DP and HDMI's encoder->infoframes_enabled, the lspcon's implementation returns its active state. (we expect enabled infoframe states of HW.) It leads to pipe state mismatch error when ddi_get_config is called. Because the current implementation of lspcon is not ready to support readout infoframes, we need to return 0 here. In order to support readout to lspcon, we need to implement read_infoframe and infoframes_enabled. And set_infoframes also have to set an appropriate bit on crtc_state->infoframes.enable Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-11-gwan-gyeong.mun@intel.com
