2024-10-30drm/i915/display: use x100 version for full version and releaseJani Nikula
Use x100, or ver * 100 + rel, versions for full IP version checks, similar to what xe driver does: - Replace IP_VER(14, 1) inline with 1401, etc. - Convert DISPLAY_VER_FULL() to DISPLAY_VERx100() - Convert IS_DISPLAY_VER_FULL() to IS_DISPLAY_VERx100() - Convert IS_DISPLAY_VER_STEP() to IS_DISPLAY_VERx100_STEP() This makes ver.rel versions easier to use, follows the xe driver pattern, and drops the dependency on the IP_VER() macro. v2: Rebase, drop IP_VER() from xe compat headers v3: Rebase Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241029155536.753413-1-jani.nikula@intel.com

itself Commit dd839aa857eb ("drm/i915: Fix incorrect assert about pending power domain async-put work") fixed the assert about a pending work dropping a display power reference asynchronously, leading to the drm_WARN_ON(!queue_delayed_work(&power_domains->async_put_work)); warn next time around a power reference was put asynchronously, due to a stale instance of the work still being pending. However the fix didn't consider the case where multiple power reference was acquired and put, requiring the work to requeue itself. Extend the fix for this case as well canceling the pending instance of the work before it requeues itself.

2024-04-19drm/i915: Convert intel_runtime_pm_get_noresume towards raw wakerefRodrigo Vivi
In the past, the noresume function was used by the GEM code to ensure wakelocks were held and bump its usage. This is no longer the case and this function was totally unused until it started to be used again by display with commit 77e619a82fc3 ("drm/i915/display: convert inner wakeref get towards get_if_in_use") However, on the display code, most of the callers are using the raw wakeref, rather then the wakelock version. What caused a major regression caught by CI. Another option to this patch is to go with the original plan and use the get_if_in_use variant in the display code, what is enough to fulfil our needs. Then, an extra patch to delete the unused _noresume variant. v2: Keep grabbing wakelock but only assert for wakeref.

2024-04-18drm/i915/display: convert inner wakeref get towards get_if_in_useRodrigo Vivi
This patch brings no functional change. Since at this point of the code we are already asserting a wakeref was held, it means that we are with runtime_pm 'in_use' and in practical terms we are only bumping the pm_runtime usage counter and moving on. However, xe driver has a lockdep annotation that warned us that if a sync resume was actually called at this point, we could have a deadlock because we are inside the power_domains->lock locked area and the resume would call the irq_reset, which would also try to get the power_domains->lock. For this reason, let's convert this call to a safer option and calm lockdep on. v2: use _noresume variant instead of get_in_use (Ville, Imre) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Imre Deak <imre.deak@intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Reviewed-by: Francois Dugast <francois.dugast@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240417203952.25503-3-rodrigo.vivi@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

Curiously at least some CHICKEN_PAR1* registers are preserved by the hardware/firmware. Unfortunately Bspec doens't really specify what gets clobbered vs. preserved so further reverse engieering might be warranted to figure out the specifics. Note that PCH_LP_PARTITION_LEVEL_DISABLE is also set by lpt_init_clock_gating() so the rmw in hsw_disable_pc8() is now redundant. Remove it.

2023-05-24drm/i915: Convert INTEL_INFO()->display to a pointerMatt Roper
Rather than embeddeding the display's device info within the main device info structure, just provide a pointer to the display-specific structure. This is in preparation for moving the display device info definitions into the display code itself and for eventually allowing the pointer to be assigned at runtime on platforms that use GMD_ID for device identification. In the future, this will also eventually allow the same display device info structures to be used outside the current i915 code (e.g., from the Xe driver). v2: - Move introduction of DISPLAY_INFO() to this patch. (Andrzej) v3: - Also use DISPLAY_INFO() in intel_display_reg_defs.h. (Andrzej) - Use "{}" instead of "{ 0 }" for empty struct init.

There's only one reference to the struct intel_dmc members dc_state, target_dc_state, and allowed_dc_mask within intel_dmc.c, begging the question why they are under struct intel_dmc to begin with. Moreover, the only references to i915->display.dmc outside of intel_dmc.c are to these members. They don't belong.

2022-11-18drm/i915/tgl+: Enable display DC power states on all eDP portsImre Deak
Starting with TGL eDP is supported on ports B+ (besides port A), so make sure DC states are not blocked on any such ports. For this add an AUX_IO_<port> power domain for each port with eDP support. These domains similarly to AUX_IO_A enable only the AUX_IO_<port> power well for an enabled port, whereas the existing AUX_<port> domains enable both the AUX_IO_<port> and the DC_OFF power wells as required by DP AUX transfers. v2: (Ville) - Split the change using AUX vs. AUX_IO on port A to a separate patch. - Select AUX_IO vs. AUX based on crtc_state->has_psr instead of is_edp(). v3: - Rebased on checking intel_encoder_can_psr() instead of crtc->has_psr. v4: - Fix warn in intel_display_power_aux_io_domain().
