Move the wrappers to call watermark hooks into intel_wm.[ch]. This declutters intel_display.c nicely. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Add new files intel_wm.[ch] and i9xx_wm.[ch] under display/ to hold generic and pre-SKL watermark code, respectively. SKL+ watermark code has already been split out to skl_watermark.[ch]. Use the _wm.[ch] naming for brevity; we may want to rename skl_watermark.[ch] later accordingly. Add new intel_wm_init() to call either skl_wm_init() or i9xx_wm_init(i915) depending on the platform, the latter comprising of the remains of intel_init_pm(). Sprinkle in some minor checkpatch fixes while moving the code. v2: - Rebase - Fix copyright year Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Detecting in intel_device_info_runtime_init() that the display is fused off or not present should only zero intel_runtime_info::pipe_mask, while the other related masks will be accordingly zeroed later in the function.

Determining whether the display engine is present on a platform happens only in intel_device_info_runtime_init(). Initializing the display power functionality depends on this condition, so move intel_power_domains_init() later after the runtime init function has been called. The next patch fixing platforms without display, depends on this patch. Acked-by:

If fbdev is not initialized for some reason - in practice on platforms without display - suspending fbdev should be skipped during system suspend, fix this up.

Since we now populate encoder->devdata for all DP capable platforms we can consult it directly during the eDP connector init instead of taking a detour via some global list/array. Unfortunately we can't quite get rid of intel_dp_is_port_edp() since it's still used by the higher level ilk/vlv/chv output setup code. Signed-off-by:

Instead of consulting vbt.ports[] lets just go through the whole child device list to check whether a specific port was declared by the VBT or not. Note that this doesn't change anything wrt. detecting duplicate child devices with the same port as vbt.ports[] would also always contain exactly one of the duplicates. v2: Include a is_port_valid() check to deal with some broken VBTs Mention something about duplicate port detection (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: -

Currently intel_bios_port_aux_ch() digs out the devdata (VBT child device info) from the vbt.ports[] array. We need to get rid of that, so just pass in the correct encoder->devdata (now that we have it also for g4x+ ports) directly. Signed-off-by:

Ville Syrjälä authored
Let's make encoder->devdata (the VBT information for the port) available on g4x+ platforms as well. Much easier when you can just grab it there instead of trying to find it from some global list array based on the port. Note that (unlike DDI platforms) we don't currently require that each DP/HDMI port is actually declared in VBT. Perhaps in the future we may want to rethink that, but for now just stick in a debug+FIXME as a reminder. Signed-off-by:

Display WA #1178 calls us to tweak some magic bits when doing AUX to an external combo PHY port. Instead of looking to see if the VBT has declared such a port (which could in theory even alias with a declared eDP port on the same PHY) just check the real situation based on the registered encoders. The only slight chicken vs. egg situation here is during output probing. But typically we'd register the eDP ports first and so once we get to probe anything external on the combo PHY we have already determined if it's eDP or not. Signed-off-by:

Replaces wm.max_level with wm.num_levels, since that generally results in nicer looking code (for-loops can be in standard form etc.). Also get rid of the two different wrappers we have for this (ilk_wm_max_level() and intel_wm_num_levels()). They don't really do anything for us other than potentially slow things down if the compiler actually emits the function calls every time (num_planes*num_wm_levels*higher_level_wm_function_calls could be a big number). The watermark code already shows up far too prominently in cpu profiles. Though I must admit that I didn't look at the generated code this time. v2: Fix the ilk_wm_merge() off-by-one (Jani) Signed-off-by:

Ville Syrjälä authored
Switch ilk+ and skl+ platforms to also setting up wm.max_level and remove a bunch of if ladders as a result. There will be a tiny change in the debugfs on CHV machines that have DVFS disabled in the BIOS. Presviously debugfs would show the latency for the DVFS level as well, but that will no longer be the case. Which is arguably better as that number is absolutely meaningless when DVFS can't be enabled anyway. Signed-off-by:

This reverts commit 0349c41b. 0349c41b ("drm/i915/hwmon: Enable PL1 power limit") is incorrect and caused a major regression on ATSM. The change enabled the PL1 power limit but FW sets the default value of the PL1 limit to 0 which implies HW now works at minimum power and therefore the lowest effective frequency. This means all workloads now run slower resulting in even GuC FW load operations timing out, rendering ATSM unusable. A different solution to the original issue of the PL1 limit being disabled on ATSM is needed but till that is developed, revert 0349c41b.

We now have some eDP+DSI dual panel systems floating around where the DSI panel is the secondary LFP and thus needs to consult "panel type 2" in VBT in order to locate all the other panel type dependant stuff correctly. To that end we need to pass in the devdata to intel_bios_init_panel_late(), otherwise it'll just assume we want the primary panel type. So let's try to just populate the vbt.ports[] stuff and encoder->devdata for icl+ DSI panels as well. We can't do this on older platforms as there we risk a DSI port aliasing with a HDMI/DP port, which is a totally legal thing as the DSI ports live in their own little parallel universe.

Turns out modern (icl+) VBTs still declare their DSI ports as MIPI-A and MIPI-C despite the PHYs now being A and B. Remap appropriately to allow the panels declared as MIPI-C to work. Cc: stable@vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8016Signed-off-by:

Previous documentation suggested that PL1 power limit is always enabled. However we now find this not to be the case on some platforms (such as ATSM). Therefore enable PL1 power limit during hwmon initialization.

Introduce a function to emits whatever commands we need at the end of the DSB command buffer. For the moment we only do the tail cacheline alignment there, but eventually we might want to eg. emit an interrupt. Signed-off-by:

Starting the DSB execution vs. waiting for it stop are two totally different things. Split intel_dsb_wait() from intel_dsb_commit() so that we can eventually allow the DSB to execute asynchronously. Signed-off-by:

After disconnecting damage worker from update logic it's left to fbdev emulation implementation to have fb_dirty function. Currently intel fbdev doesn't have it. This is causing problems to features (PSR, FBC, DRRS) relying on dirty callback. Implement simple fb_dirty callback to deliver notifications about updates in fb console. v4: Add proper Fixes tag and modify commit message v3: Check damage clip v2: Improved commit message and added Fixes tag Fixes: f231af49 ("drm/fb-helper: Disconnect damage worker from update logic") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

Add validity checks for the dmc ids computed from pipe parameters in intel_dmc_enable_pipe() and intel_dmc_disable_pipe(). It's slightly difficult for humans and static analyzers alike to ensure the resulting dmc ids are within bounds. Just check them and reject invalid ones. Signed-off-by:
