DP_PSR_EN_CFG bit 5 aka "Selective Update Region Scan Line Capture Indication" in eDP spec has a ambiguous name, so renaming to better match specification. While at it, replacing bit shit by BIT() macro and adding the version some registers were added to eDP specification.

We can handle the surface alignment of CCS and UV color planes for all modifiers at one place, so do this. An AUX color plane can be a CCS or a UV plane, use only the more specific query functions and remove is_aux_plane() becoming redundant. While at it add a TODO for linear UV color plane alignments. The spec requires this to be stride-in-bytes * 64 on all platforms, whereas the driver uses an alignment of 4k for gen<12 and 256k for gen>=12 for linear UV planes. v2: - Restore previous alignment for linear UV surfaces.

Screen flickers on Innolux eDP 1.3 panel when clock rate 540000 is in use. According to the panel vendor, though clock rate 540000 is advertised, but the max clock rate it really supports is 270000. Ville Syrjälä mentioned that fast and narrow also breaks some eDP 1.4 panel, so use slow and wide training for all panels to resolve the issue. User also confirmed that the new strategy doesn't introduce any regression on XPS 9380. v2: - Use slow and wide for everything.

In case AUX failures happen unexpectedly during a modeset, the driver should still complete the modeset. In particular the driver should perform the link training sequence steps even in case of an AUX failure, as this sequence also includes port initialization steps. Not doing that can leave the port/pipe in a broken state and lead for instance to a flip done timeout. Fix this by continuing with link training (in a no-LTTPR mode) if the DPRX DPCD readout failed for some reason at the beginning of link training. After a successful connector detection we already have the DPCD read out and cached, so the failed repeated read for it should not cause a problem. Note that a partial AUX read could in theory partly overwrite the cached DPCD (and return error) but this overwrite should not happen if the returned values are corrupted (due to a timeout or some other IO error). Kudos to Ville to root cause the problem.

Like it was done in commit 01eb15c9 ("drm/i915: Add DISPLAY_VER() and related macros") add the correspondent macros for graphics and media. Going forward we will prefer checking the versions for the specific IPs (graphics, media and display) rather than grouping everything under a "gen" version. For consistency and to make the maintenance easier, it'd be preferred not to mix the *GEN* macros with the new ones. For older platforms we can simply consider that the previous "gen" number will extend to all 3 IPs. Then we can start replacing its use in the driver. Right now this replacement is not done and only the infrastructure is put in place. We also leave gen and gen_mask inside struct intel_device_info while it's still being used throughout the code. v2: Repurpose IS_{GRAPHICS,MEDIA}_VER() macros to work with a range Signed-off-by:

Lucas De Marchi authored
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:

The macro we use to check is called DISPLAY_VER(). While using this macro and the new ones being added in following changes I made the mistake multiple times when mixing both "ver" and "version". Although it's usually better to prefer the complete name, the shorhand DISPLAY_VER() / GRAPHICS_VER / MEDIA_VER are clear and cause less visual polution. Another issue is when copying the variable to other places. "display.version" would be copied to a "display_version" variable which is long and would make people abbreviate as "version", or "display_ver". In the first case it's not always clear what version refers to, and in the second case it just hints it should be the name in the first place. So, in the same way use used "gen" rather than "generation", use "ver" instead of "version". Signed-off-by:
