Looks like we never updated intel_bios_is_port_dp_dual_mode() when the VBT port mapping became erratic on modern platforms. This is causing us to look up the wrong child device and thus throwing the heuristic off (ie. we might end looking at a child device for a genuine DP++ port when we were supposed to look at one for a native HDMI port). Fix it up by not using the outdated port_mapping[] in intel_bios_is_port_dp_dual_mode() and rely on intel_bios_encoder_data_lookup() instead. Cc: stable@vger.kernel.org Tested-by:

Now that the bigjoiner state readout/computation has been made to do the right thing nuke the related state checker quirk. Reviewed-by:

Ville Syrjälä authored
Try to make bigjoiner pipes less special. The main things here are that each pipe now does full clock computation/readout with its own shared_dpll reference. Also every pipe's cpu_transcoder always points correctly at the master transcoder. Due to the above changes state readout is now complete and all the related hacks can go away. The actual modeset sequence code is still a mess, but I think in order to clean that up properly we're probably going to have to redesign the modeset logic to treat transcoders vs. pipes separately. That is going to require significant amounts of work. Reviewed-by:

The PPS SDP is fed into the transcoder whereas the DSC block is (or at least can be) per pipe. Let's split these into two distinct operations in an effort to untagle the bigjoiner mess where we have two pipes feeding a single transcoder. Reviewed-by:

Let's disable planes on all pipes affected by the modeset before we start doing the actual modeset. This means we have less random planes enabled during the modeset, and it also mirrors what we already do when enabling pipes on skl+ since we enable planes on all pipes as the very last step. As a bonus we also nuke a bunch og bigjoiner special casing. I've occasionally pondered about going even furher here and doing the pre_plane_update() stuff for all pipes first, then actually disabling the planes, and finally running the rest of the modeset sequence. This would potentially allow parallelizing all the extra vblank waits across multiple pipes, and would make the plane disable even more atomic. But let's go one step a time here.

Disabling planes in the middle of the modeset seuqnece does not make sense since userspace can anyway disable planes before the modeset even starts. So when the modeset seuqence starts the set of enabled planes is entirely arbitrary. Trying to sprinkle the plane disabling into the modeset sequence just means more randomness and potential for hard to reproduce bugs. So it makes most sense to just disable all planes first so that the rest of the modeset sequence remains identical regardless of which planes happen to be enabled by userspace at the time. This reverts commit 84030adb. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

PSR2 apparently requires some planes to be enabled for some silly reason, and so we are now trying to turn PSR off before planes go off. Except during a full modeset that is handled less clearly through reorganization of the modeset sequence. That is not great as it makes the code mode complex, and prevents us from doing nice things such as just turning off all the planes at the very start of the modeset. So let's move the PSR pre_plane_update() thing to a spot where it will handle both full modesets and everything else. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

Alderlake-P was getting 'max time under evasion' messages when PSR2 is enabled, this is due PIPE_SCANLINE/PIPEDSL returning 0 over a period of time longer than VBLANK_EVASION_TIME_US. For PSR1 we had the same issue so intel_psr_wait_for_idle() was implemented to wait for PSR1 to get into idle state but nothing was done for PSR2. For PSR2 we can't only wait for idle state as PSR2 tends to keep into sleep state(ready to send selective updates). Waiting for any state below deep sleep proved to be effective in avoiding the evasion messages and also not wasted a lot of time. v2: - dropping the additional wait_for loops, only the _wait_for_atomic() is necessary - waiting for states below EDP_PSR2_STATUS_STATE_DEEP_SLEEP v3: - dropping intel_wait_for_condition_atomic() function Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Signed-off-by:

If we want to return from for_each_intel_connector_iter(), one way is calling drm_connector_list_iter_end() before returning to avoid memleak. The other way is just breaking from the bracket and then returning after the outside drm_connector_list_iter_end(). Obviously, the second way makes code smaller and more clear. Apply it to the function intel_dp_mst_atomic_master_trans_check(). Signed-off-by:

Introduce a small helper which given the crtc state tells us whether we're output YCbCr 4:2:0 or not. For native HDMI this is rather simple as we just look at the output_format. But I think the helper is beneficial since with DP HDMI DFPs we're going to need a more complex variant, and I want to unify the DP and HDMI sides of that as much as possible. Signed-off-by:

intel_hdmi_bpc_possible() is used by the DP code as well where the native HDMI source limits do not apply. So let's split this into a pair of functions: one for the source vs. one for the sink. This is basically reverting some of commit 41828125 ("drm/i915: Move platform checks into intel_hdmi_bpc_possible()") slightly, but in a nicer form. I guess I forgot at the time that the DP side uses this too. Signed-off-by:

Future platforms change the location of CCS AUX planes in CCS framebuffers, so add intel_fb_is_ccs_aux_plane() to query for these planes independently of the platform. This function can be used everywhere instead of is_ccs_plane() (or is_ccs_plane() && !cc_plane()), since all the callers are only interested in CCS AUX planes (and not CCS color-clear planes). Add the corresponding intel_fb_is_gen12_ccs_aux_plane(), which can be used everywhere instead of is_gen12_ccs_plane(), based on the above explanation. This change also unexports the is_gen12_ccs_modifier(), is_gen12_ccs_plane(), is_gen12_ccs_cc_plane() functions as they are only used in intel_fb.c v1-v2: Unchanged v3: (Ville) - Use ccs_aux instead of the ccs_ctrl term everywhere. - Use color_plane instead of plane term for FB plane indicies. v4: Fix version range check.

CCS CC planes are quite different from CCS AUX planes, even though we regard the CC planes as a linear buffer having a 64 byte stride. Thus it's clearer to check for either CCS plane types explicitly when we need to handle them; add the required CCS CC planes check here, while the next patch will change all is_ccs_plane()/is_gen12_ccs_plane() checks to consider only the CCS AUX planes.

Add a table describing all the framebuffer modifiers used by i915 at one place. This has the benefit of deduplicating the listing of supported modifiers for each platform and checking the support of these modifiers on a given plane. This also simplifies in a similar way getting some attribute for a modifier, for instance checking if the modifier is a CCS modifier type. While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(), as the cursor plane is registered with DRM core elsewhere. v1: Unchanged. v2: - Keep the plane caps calculation in the plane code and pass an enum with these caps to intel_fb_get_modifiers(). (Ville) - Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as well. v3: - s/.id/.modifier/ (Ville) - Keep modifier_desc vs. plane_cap filter conditions consistent.

Imre Deak authored
If the DPCD sink rate values read from the sink are invalid, the driver will sanitize this in intel_dp_set_common_rates(), by setting a default 162000 link rate in common rates and printing a WARN(). WARN()s should only be triggered by bugs in the code and not by external factors like the above (an invalid DPCD injected maliciously or read from a buggy monitor). So fixup the invalid DPCD sink rate values already and print an error in this case (since it's still a user visible problem). Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:
