According to some VBIOS sources the LFP power block used to have a single bit for DPST support. In version 159 that bit got moved into the driver features block, and then in version 228 back into the LFP power block (but this time as a per-panel thing). We have definitions for the last two, but not the original bit. Define it as well. Signed-off-by:

While the spec does claim that most of the driver feature flags start from BDB version 165, reality and some VBIOS code disagrees. The VBIOS code says it starts from version 159, and my ILK with version 162 definitely has these things already in its VBT. Update the version number comments to say 159+ for all the bits that seem relevant for pre-hsw hardware. Signed-off-by:

The encoder is a much more useful thing to pass around than the i915 and port combo. Also drive-by clean up some cases where both i915 and encoder are passed; only the latter is needed. Reviewed-by:

Wherever possible, replace the port/phy based functions with the encoder based functions: intel_is_c10phy() -> intel_encoder_is_c10phy() intel_phy_is_combo() -> intel_encoder_is_combo() intel_phy_is_tc() -> intel_encoder_is_tc() intel_port_to_phy() -> intel_encoder_to_phy() intel_port_to_tc() -> intel_encoder_to_tc() Reviewed-by:

Add a number of encoder based functions to check if the port/phy of the encoder is of a certain type, or to convert to phy or tc_port. Initially these are just wrappers around the existing functions, but they can be improved to use VBT data or use some cached info in the future. Reviewed-by:

If the sink supports 128b/132b and single-stream sideband messaging, enable MST mode. With this, the topology manager will still write DP_MSTM_CTRL, which should be ignored by the sink. In the future, the topology manager should probably only set the sideband messaging related parts of the register.

Rename intel_dp_can_mst() to intel_dp_mst_detect(), and move all DP MST detect debug logging there. Debug log the sink's MST capability, including single-stream sideband messaging support, and the decision whether to enable MST mode or not. Do this regardless of whether we're actually enabling MST or not. We need to detect MST in intel_dp_detect_dpcd() before the earlier returns, but try not to change the logic otherwise. v2: - Use "MST", "SST w/ sideband messaging", and "SST" for logging (Ville) - Return MST mode from intel_dp_mst_detect() - Do MST detect before early returns from intel_dp_detect_dpcd() Cc: Arun R Murthy <arun.r.murthy@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Our definitions for bit 7 and bit 0 of ICL_PORT_TX_DW6 are swapped. Functionally it doesn't matter as we always set both bits, but let's rename the bits to match bspec 100%. And while at it, add the definition for bits 1-6 as well, just to have it all fully documented. Signed-off-by:

For Earlier platforms, the Pipe source size is 12-bits so max pipe source width and height is 4096. For newer platforms it is 13-bits so theoretically max width/height is 8192. For few of the earlier platforms the scaler did not use all bits of the PIPESRC, so max scaler source size was used to make that the pipe source size is programmed within limits, before using scaler. This creates a problem, for MTL where scaler source size is 4096, but max pipe source width can theroretically be 8192. Switch the check to use the max scaler destination size, which closely match the limits. Signed-off-by:

Since commit 0c65dc06 ("drm/i915/jsl: s/JSL/JASPERLAKE for platform/subplatform defines"), boot freezes on a Jasper Lake tablet (Librem 11), usually with graphical corruption on the eDP display, but sometimes just a black screen. This commit was included in 6.6 and later. That commit was intended to refactor EHL and JSL macros, but the change to ehl_combo_pll_div_frac_wa_needed() started matching JSL incorrectly when it was only intended to match EHL. It replaced: return ((IS_PLATFORM(i915, INTEL_ELKHARTLAKE) && IS_JSL_EHL_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) || with: return (((IS_ELKHARTLAKE(i915) || IS_JASPERLAKE(i915)) && IS_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) || Remove IS_JASPERLAKE() to fix the regression.

Utilize drm_printer in pipe_config_infoframe_mismatch() to avoid a bit of code duplication. print_hex_dump() doesn't know anything about the printer so it still needs the DRM_UT_KMS check and special handling for the loglevel. But at least we end up with a bit less copy-pasta. Signed-off-by:

Utilize drm_printer in pipe_config_infoframe_mismatch() to avoid a bit of code duplication. hdmi_infoframe_log() can't use the printer of course, but for that we can just figure out which loglevel to use. And we do need to keep the explicit drm_debug_enabled(DRM_UT_KMS) since hdmi_infoframe_log() won't do it for us. Signed-off-by:

commit 64f6a5d1 ("container_of: add container_of_const() that preserves const-ness of the pointer") is nice. Let's use it so that we don't accidentally cast away the const from our state pointers. The only thing I don't particularly like about container_of_const() is that it still accepts void* in addition to the proper pointer types, but that's how most other things in C work anyway so I guess we can live with it. And while at it rename the macro arguments to be a bit more descriptive than just 'x'. TODO: maybe convert *all* container_of() uses to container_of_const()? Signed-off-by:

Bspec mentions 50 us for IO wake time and 32 us for fast wake time. 32 us is most probably wrong as it doesn't meet the specification as fast wake time is calculated in Bspec like this: 10..16 us (precharge) + 8 us (preamble) + 4 us (phy_wake) + 20 us (tfw_exit_latency) Instead of using these constants calculate IO wake and fast wake for DISPLAY_VER < 12 as well. v3: - do not handle < 9 separately - add own helper for skl and tgl io buffer wake times v2: - initialize io/fast_wake_time for display version < 9 Signed-off-by:

Current fast and IO wake lines calculation is assuming fast wake sync length is 18 pulses. Let's improve this by checking actual length. Add getter for IO buffer wake time and return 10 us there which was assumed with static 42 us IO wake time. Upcoming patches will extent this for different display versions. Bspec: 65450 v3: - s/get_io_buffer_wake_time/io_buffer_wake_time/ and use it directly in calculation. v2: - rename io_wake_time in if block to io_buffer_wake_time - rename get_io_wake_time to get_io_buffer_wake_time Signed-off-by:
