commit 64f6a5d1922b ("container_of: add container_of_const() that preserves const-ness of the pointer") is nice. Let's use it so that we don't accidentally cast away the const from our state pointers. The only thing I don't particularly like about container_of_const() is that it still accepts void* in addition to the proper pointer types, but that's how most other things in C work anyway so I guess we can live with it.

Commit 1fd4a5a36f9f ("drm/connector: Rename legacy TV property") failed to update all the users of the struct drm_tv_connector_state mode field, which resulted in a build failure in i915. However, a subsequent commit in the same series reintroduced a mode field in that structure, with a different semantic but the same type, with the assumption that all previous users were updated. Since that didn't happen, the i915 driver now compiles, but mixes accesses to the legacy_mode field and the newer mode field, but with the previous semantics. This obviously doesn't work very well, so we need to update the accesses that weren't in the legacy renaming commit.

2024-01-08drm/i915: Init DRM connector polled field earlyImre Deak
After an HPD IRQ storm on a connector intel_hpd_irq_storm_detect() will set the connector's HPD pin state to HPD_MARK_DISABLED and the IRQ gets disabled. Subsequently intel_hpd_irq_storm_switch_to_polling() will enable polling for these connectors, setting the pin state to HPD_DISABLED, but only if the connector's base.polled field is set to DRM_CONNECTOR_POLL_HPD. intel_hpd_irq_storm_reenable_work() will reenable the IRQ - after 2 minutes - if the pin state is HPD_DISABLED. The connectors will be created with their base.polled field set to 0, which gets initialized only later in i915_hpd_poll_init_work() (using intel_connector::polled). If a storm is detected on a connector after it's created and IRQs are enabled on it - by intel_hpd_init() - and before its bease.polled field is initialized in the above work, the connector's HPD pin will stay in the HPD_MARK_DISABLED state - leaving the IRQ disabled indefinitely - and polling will not get enabled on it as intended. I can't see a reason for initializing base.polled in a delayed manner, so do this already when creating the connector, to prevent the above race condition.

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.

2023-05-05drm/i915/display: Add new member to configure PCON color conversionAnkit Nautiyal
The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch adds new member to crtc_state to represent the final output_format to the sink. In case of a DFP this can be different than the output_format, as per the format conversion done via the PCON. This will help to store only the format conversion capabilities of the DP device in intel_dp->dfp, and use crtc_state to compute and store the configuration for color/format conversion for a given mode. v2: modified the new member to crtc_state to represent the final output_format that eaches the sink, after possible conversion by PCON kind of devices.

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.

2022-09-13drm/i915: Fix TV encoder clock computationVille Syrjälä
The TV encoder has its own special clocking strategy, which means we can't just use intel_crtc_dotclock() to figure out what the resulting dotclock will be given the actual DPLL port_clock. Additionally the DPLL can't always generate exactly the frequency we initially asked for. This results in us computing a bogus dotclock/etc., and it won't match the readout which is handled by the encoder itself properly. Naturally the state checker becomes unhappy with the mismatch. To do this sanely we'll need to move the DPLL computation into encoder->compute_config() so that all the derived state gets correctly computed based on the actual DPLL output frequency. Start doing that just for the TV encoder initally as intel_crtc_dotclock() should be able to handle other encoder types well enough. Though eventually this should be done for all encoder types rather than doing it from intel_crtc_compute_config(). With this we actually do some of the DPLL state computation twice, but we can skip the second actual .find_dpll() search by flagging .clock_set=true after we've done it once. We also still need to avoid clobbering the correct adjusted_mode.crtc_clock set up by encoder->compute_config() when called a second time from intel_crtc_compute_config().

2021-09-15drm/i915: s/pipe/transcoder/ when dealing with PIPECONF/TRANSCONFVille Syrjälä
PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder. Bigjoiner is making life even more confusing by introducing a N:1 relationship between pipes and transcoders. In that case we only enable/configure the transcoder corresponding to the master pipe. Let's do some renames to make it clear we're dealing with the transcoder rather than pipe when it comes to PIPECONF/TRANSCONF. I decided to leave the _cpu_ part out from the function/macro names since the PCH transcoder related stuff already has a _pch_ in their name. So shouldn't be possible to confuse them.

2021-04-14drm/i915/display: rename display version macrosLucas De Marchi
While converting the rest of the driver to use GRAPHICS_VER() and MEDIA_VER(), following what was done for display, some discussions went back on what we did for display: 1) Why is the == comparison special that deserves a separate macro instead of just getting the version and comparing directly like is done for >, >=, <=? 2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for brevity. If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators. Aside from the definition changes, this was done by the following semantic patch: @@ expression dev_priv, E1; @@ - !IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) != E1 @@ expression dev_priv, E1; @@ - IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) == E1 @@ expression dev_priv, from, until; @@ - IS_DISPLAY_RANGE(dev_priv, from, until) + IS_DISPLAY_VER(dev_priv, from, until) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> [Jani: Minor conflict resolve while applying.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20210413051002.92589-4-lucas.demarchi@intel.com

2020-05-29drm/i915: Stop using mode->private_flagsVille Syrjälä
Replace the use of mode->private_flags with a truly private bitmaks in our own crtc state. We also need a copy in the crtc itself so the vblank code can get at it. We already have scanline_offset in there for a similar reason, as well as the vblank->hwmode which is assigned via drm_calc_timestamping_constants(). Fortunately we now have a nice place for doing the crtc_state->crtc copy in intel_crtc_update_active_timings() which gets called both for modesets and init/resume readout. The one slightly iffy spot is the INHERITED flag which we want to preserve until userspace/fb_helper does the first proper commit after actually calling .detecti() on the connectors. Otherwise we don't have the full sink capabilities (audio,infoframes,etc.) when .compute_config() gets called and thus we will fail to enable those features when the first userspace commit happens. The only internal commit we do prior to that should be from intel_initial_commit() and there we can simply preserve the INHERITED flag from the readout. v2: Deal with INHERITED in sanitize_watermarks() as well CC: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200429103904.11727-1-ville.syrjala@linux.intel.com
