On pre-ddi platforms we have slightly different code being used for HDMI TMDS clock to dotclock conversion between the state computation and state readout. Both of these need to round the same way in order to not get a mismatch between the computed and read out states. Fix up the rounding direction in the readout path to match what is used during state computation. Another option would to just use intel_crtc_dotclock() in the readout path as well, but I don't really want to do that as the current code more accurately represents how the hardware really works; The HDMI port register defines whether we're actually outputting 8bpc or 12bpc over HDMI, and the PIPECONF bpc setting just defines what goes over FDI between the CPU and PCH. The fact that we try to cram all that into a single pipe_bpp during state computation is perhaps not entirely great... Fixes: f2c9df10 ("drm/i915: Round TMDS clock to nearest") Signed-off-by:

During system resume DP MST requires AUX to be working already before the HW state readout of the given encoder. Since AUX requires the encoder/PHY TypeC mode to be initialized, which atm only happens during HW state readout, these AUX transfers can change the TypeC mode incorrectly (disconnecting the PHY for an enabled encoder) and trigger the state check WARNs in intel_tc_port_sanitize(). Fix this by initializing the TypeC mode earlier both during driver loading and system resume and making sure that the mode can't change until the encoder's state is read out. While at it add the missing DocBook comments and rename intel_tc_port_sanitize()->intel_tc_port_sanitize_mode() for consistency. Signed-off-by:

Do all the checks in intel_dp_initial_fastset_check() instead of bailing out on the first condition that triggers. This makes for better debug logs since we see all the reasons why the full modeset computation is forced. Also avoid the risk of someone accidentally adding a check later in the function that would require connectors_changed=true (ie. no fastset at all), but an earlier check may have already bailed out with just mode_changed=true (ie. fastset is still possible). Pimp the debugs with the encoder id+name while at it. v2: Call the return variable 'fastset' to convey its meaning Signed-off-by:

We always allocate two DPLLs (TC and TBT) for TC ports. This is because we can't know ahead of time wherher we need to put the PHY into DP-Alt or TBT mode. However during readout we can obviously only read out the state of the DPLL that the port is actually using. Thus the state after readout will not have both DPLLs populated. We run into problems if during readout the TC port is in DP-Alt mode, but we then perform a modeset on the port without going through the full .compute_config() machinery, and during said modeset the port cannot be switched back into DP-Alt mode and we need to take the TBT fallback path. Such a modeset can happen eg. due to cdclk reprogramming. This wasn't a problem earlier because we did all the DPLL calculations much later in the modeset. So even if flagged a modeset very late we'd still have gone through the DPLL calculations. But now all the DPLL calculations happen much earlier and so we need to deal with it, or else we'll attempt a modeset without a DPLL. To guarantee that we always have both DPLLs fully cal/ulated for TC ports force a full modeset computation during the initial commit. v2: Avoid bitwise operation on bool (Jani) Call the return variable 'fastset' to convey its meaning Reported-by:Lee Shawn C <shawn.c.lee@intel.com> Fixes: b000abd3 ("drm/i915: Do .crtc_compute_clock() earlier") Signed-off-by:

Commit 00c6cbfd ("drm/i915: move pipe_mask and cpu_transcoder_mask to runtime info") moved the pipe_mask member from struct intel_device_info to intel_runtime_info, but overlooked some of our platforms initializing device info .display = {}. This is significant, as pipe_mask is the single point of truth for a device having a display or not; the platforms in question left pipe_mask to whatever was set for the platforms they "inherit" from in the complex macro scheme we have. Add new NO_DISPLAY macro initializing .__runtime.pipe_mask = 0, which will cause the device info .display sub-struct to be zeroed in intel_device_info_runtime_init(). A better solution (or simply audit of proper use of HAS_DISPLAY() checks) is required before moving forward with [1]. Also clear all the display related members in runtime info if there's no display. The latter is a bit tedious, but it's for completeness at this time, to ensure similar functionality as before.

We can simplify the vlv watermark sanitation by reusing the second half of vlv_compute_pipe_wm() to convert the sanitized raw watermarks into the proper form to be used as the optimal/intermediate watermarks. Also to be consistent with normal watermark computation the sanitized watermarks should be all 0 for any disabled plane. Previously we zeroed out the watermarks only up to the level (ie. PM2/5/DVDFS) that was enabled. Signed-off-by:

In the unlikely case of not finding a fixed mode don't register the eDP connector. I think there are some places where we'd oops if we didn't have a fixed mode for eDP so presumable this doesn't typically happen. But better safe than sorry. Also pimp the debugs with the encoder id+name. I think dumping the encoder rather than the connector provides more information here (eg. to match against the port information in the VBT). We can also drop the extra check from intel_edp_add_properties(). Signed-off-by:

Use *_hpd_invert() helpers whenever possible to isolate logic specific to hotplug inversion from common HPD setup logic to improve readability and maintainability of the source code. While we only define dg1_hpd_invert() here, future platforms are likely to have different hotplug inversion needs, thus it makes sense grouping different implementations under a common suffix. v2: Fix coding style and prefer to use small *_hdp_invert() helpers instead of a generic one.

Expand the current stepping convention to accommodate the GMD stepping info. Typically GMD step maps to letter stepping by "A + step %4" and number to "A + step /4" i.e, GMD step 0 maps to STEP_A0, 1 to _A1, 2 to _A2, 3 to _A3, 4 to STEP_B0... Future platforms might break this formulae and may require a table mapping to decode GMD step compatible with the convention. v2: - Pass the updated ip version structure v3: - Skip using GMD to step table(MattR) Cc: Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by:

Going forward, the hardware teams no longer consider new platforms to have a "generation" in the way we've defined it for past platforms. Instead, each IP block (graphics, media, display) will have their own architecture major.minor versions and stepping ID's which should be read directly from a register in the MMIO space. Bspec: 63361, 64111 v2: - Move the IP version readout to intel_device_info.c - Convert the macro into a function v3: - Move subplatform init to runtime early init - Cache runtime ver, release info to compare with hardware values. - Use IP_VER for snaity check(MattR) v4: - Minor doccumentation changes. - Normalize HAS_GMD_ID macro value.(JaniN) Signed-off-by:
