Instead of warning and continuing with bogus state when the requested dotclock isn't acceptable just print some debug spew and fail gracefully. Signed-off-by:

port_clock is what the encoder/dpll code is supposed to calculate, it is not the input clock. Use the dotclock as the target we're trying to achieve instead. TODO: the SDVO TV clocking is a mess atm and needs further work Signed-off-by:
-
Ville Syrjälä authored
Call *_calc_dpll_params() even in cases where the encoder has computed the DPLL params for us. The SDVO TV output code doesn't populate crtc_state->dpll.dot leading to the dotclock getting calculated as zero, and that leads to all kinds of real problems. The g4x DP code also doesn't populate the derived dividers nor .vco, which could also create some confusion. Signed-off-by:
-
Ville Syrjälä authored
Allow *_calc_dpll_params() to be called even if the N/P dividers are zero without warning. We'll want to call these to make sure the derived values are fully computed, but not all users (VLV DSI in particular) even enable the DPLL and thus the dividers will be left at zero. It could also be possible that the BIOS has misprogrammed the DPLL (IIRC happened with some SNB machines with 4k+ displays) and thus we'll currently generate a lot of dmesg spew. Better be silent and just let the normal state checker/etc. deal with any driver bugs. Signed-off-by:

The SDVO inputs are reported a simple number, not a bitmask. Adjust the code to match reality. Note that we don't actually support dual input SDVO devices, and we just always use the first input. Signed-off-by:

I have at least one SDVO device (some Lenovo DVI-I ADD2 card, based on Conexant CX25904) where GetAttachedDisplays returns success but fails to report any attached displays unless we precede the command with a SetTargetOutput. Make it so. I wasn't able to spot anything in the SDVO spec stating that this should be necessary, but real world wins over spec. Signed-off-by:

After the commit in the Fixes: line below, HPD polling stopped working on i915, since after that change calling drm_kms_helper_poll_enable() doesn't restart drm_mode_config::output_poll_work if the work was stopped (no connectors needing polling) and enabling polling for a connector (during runtime suspend or detecting an HPD IRQ storm). After the above change calling drm_kms_helper_poll_enable() is a nop after it's been called already and polling for some connectors was disabled/re-enabled. Fix this by calling drm_kms_helper_poll_reschedule() added in the previous patch instead, which reschedules the work whenever expected.

Add a helper to reschedule drm_mode_config::output_poll_work after polling has been enabled for a connector (and needing a reschedule, since previously polling was disabled for all connectors and hence output_poll_work was not running).

Most of the IS_METEORLAKE checks in the display code shouldn't actually be tied to MTL as a platform, but rather to the Xe_LPD+ display IP (which is used in MTL, but may show up again in future platforms). In cases where we're trying to match that specific IP, use a version check against IP_VER(14, 0). For cases where we're just handling new behavior introduced by this IP (but which may also be inherited by future IP as well), use a ver >= 14 check. The one exception here is the stolen memory workaround Wa_13010847436 (which is mislabelled as "Wa_22018444074" in the code). That's truly a MTL-specific issue rather than being tied to any of the IP blocks, so leaving the condition as IS_METEORLAKE is correct there. v2: - cdclk check should be >=, not >.

Stepping-specific display behavior shouldn't be tied to MTL as a platform, but rather specifically to the Xe_LPD+ IP. Future non-MTL platforms may re-use this IP and will need to follow the exact same logic and apply the same workarounds. IS_MTL_DISPLAY_STEP() is dropped in favor of a new macro IS_DISPLAY_IP_STEP() that only checks the display IP version. v2: - Rename macro to IS_DISPLAY_IP_STEP for consistency with the corresponding GT macro and handle steppings the same way. v3: - Drop the automatic "STEP_" pasting. v4: - Implement IS_DISPLAY_IP_STEP on top of IS_DISPLAY_IP_RANGE / IS_DISPLAY_STEP building blocks and make the parameters from/until instead of begin/fixed.

Currently for testing an output format with DSC, we just force the output format, without checking if it can be supported. This also creates an issue where there is a PCON which might need to convert from forced output format to the format to sink format. Signed-off-by:

Use checks for src and sink limits before computing compressed bpp for eDP. Signed-off-by:

Ankit Nautiyal authored
Currently, we take the max lane, rate and pipe bpp, to get the maximum compressed bpp possible. We then set the output bpp to this value. This patch provides support to have max bpp, min rate and min lanes, that can support the min compressed bpp. v2: -Avoid ending up with compressed bpp, same as pipe bpp. (Stan) -Fix the checks for limits->max/min_bpp while iterating over list of valid DSC bpcs. (Stan) v3: -Refactor the code to have pipe bpp/compressed bpp computation and slice count calculation separately for different cases. v4: -Separate the pipe_bpp calculation for eDP and DP. v5: -Get rid of magic numbers for max and min bpp, and improve documentation. (Stan). -Use functions for {src_sink}_{min_max}_compressed_bpp (Ville). v6: -Remove lines to set link config to max. v7: -Split the part to separate edp and dp functions for computing DSC BPP into separate patch. v8: -Separate mechanism to get compressed bpp for ICL,TGL and XELPD+.

For DSC the min BPC is 8 for ICL+ and so the min pipe_bpp is 24. Check this condition for cases where bpc is forced by debugfs flag dsc_force_bpc. If the check fails, then WARN and ignore the debugfs flag. For MST case the pipe_bpp is already computed (hardcoded to be 24), and this check is not required. Signed-off-by:

As per Bsepc:49259, Bigjoiner BW check puts restriction on the compressed bpp for a given CDCLK, pixelclock in cases where Bigjoiner + DSC are used. Currently compressed bpp is computed first, and it is ensured that the bpp will work at least with the max CDCLK freq. Since the CDCLK is computed later, lets account for Bigjoiner BW check while calculating Min CDCLK. v2: Use pixel clock in the bw calculations. (Ville) v3: Use helper to account for FEC overhead.

Currently there are many places where we use output_bpp for link bpp and compressed bpp. Lets use consistent naming: output_bpp : The intermediate value taking into account the output_format chroma subsampling. compressed_bpp : target bpp for the DSC encoder. link_bpp : final bpp used in the link. For 444 sampling without DSC: link_bpp = output_bpp = pipe_bpp For 420 sampling without DSC: output_bpp = pipe_bpp / 2 link_bpp = output_bpp For 444 sampling with DSC: output_bpp = pipe_bpp link_bpp = compressed_bpp, computed with output_bpp (i.e. pipe_bpp in this case) For 420 sampling with DSC: output_bpp = pipe_bpp/2 link_bpp = compressed_bpp, computed with output_bpp Signed-off-by:

The final link bpp used to calculate the m_n values depend on the output_format. Though the output_format is set to RGB for MST case and the link bpp will be same as the pipe bpp, for the sake of semantics, lets calculate the m_n values with the link bpp, instead of pipe_bpp. Signed-off-by:
