According to chapter "Sending Commands to the Panel" in bspec #29738 and #49188. If driver try to send DCS long pakcet, we have to program TX payload register at first. And configure TX header HW register later. DSC long packet would not be sent properly if we don't follow this sequence.

Driver should wait for free header or payload buffer in FIFO. It would be good to wait a while for HW to release credit before give it up to write to HW. Without sending initailize command sets completely. It would caused MIPI display can't light up properly.

Frontbuffer rendering will be dropped for modern platforms but before that we to prepare DRRS for it. intel_drrs_flush and intel_drrs_invalidate will not be called for platforms that will not support frontbuffer rendering so DRRS needs another way to be notified about to page flips so it can change between high and low refresh rates as needed.

Avoid extra caching of the data. This is slightly more subtle than one would think. For one thing, we explicitly ignore 0 value in child device ddc pin; this is specified as N/A and does not warrant a warning. For another, we start looking for ddc pin collisions in sanitize using unmapped pin numbering. v2: Check !devdata in intel_bios_alternate_ddc_pin() Cc: José Roberto de Souza <jose.souza@intel.com> Reviewed-by:

intel_dp_set_source_rates() calls intel_dp_is_edp(), which is unsafe to use before intel_encoder->type is set. This causes incorrect max source rate to be used for display 11+. On EHL and JSL, HBR3 is used instead of HBR2, and on the other affected platforms, HBR2 is used instead of HBR3. Move intel_dp_set_source_rates() to after intel_encoder->type is set. Add comment to intel_dp_is_edp() describing unsafe usages. Cleanup intel_dp_init_connector() while at it. Note: The same change was originally added as commit 680c45c7 ("drm/i915/dp: Correctly advertise HBR3 for GEN11+"), but later reverted due to issues in CI in commit d3913019 ("Revert "drm/i915/dp: Correctly advertise HBR3 for GEN11+"").

The memory latency values returned by pcode on DG2 are in units of "2 usec" rather than 1 usec on all other platforms. I.e., we need to double the value returned by pcode to obtain the true latency value. The bspec wording here was a bit ambiguous as to whether it wanted us to multiply or divide the pcode value by two, but we confirmed offline with the hardware team that we need to double the value the pcode gives us; this change is intended to support a larger range of potential latency values.
