[PATCH v3 00/13] drm/i915/dsi: enable DSC

[Jani Nikula]

3rd try at enabling DSC on ICL+ DSI. Something very close to this was
tested to work by Vandita.

BR,
Jani.

[Jani Nikula]

Check for child devices that specify compression, and store the device

Use fairly rigid checks for compression data for starters. These can be
made more dynamic later.

Log about DSC presence in DDI port parse, though this is not universal
across platforms or port types (DSI).

[PATCH v3 03/13] drm/i915/bios: add support for querying DSC details for encoder

[Jani Nikula]

Add function for retrieving the DSC data for an encoder.

Initially, this is DSI specific, as DP does not use VBT settings for DSC
at all. It's also not very pretty.

In the future we might have a pointer from encoder to the child device,
which would make the child device list query here so much more sensible.

v3:
- use crtc_state instead of pipe_config
- return true by default from intel_bios_get_dsc_params()
- expand the comment about rc_buffer_block_size and rc_buffer_size

v2:
- make more robust, debug log errors better

[Intel-gfx] [PATCH v3 03/13] drm/i915/bios: add support for querying DSC details for encoder

[Jani Nikula]

Add function for retrieving the DSC data for an encoder.

Initially, this is DSI specific, as DP does not use VBT settings for DSC
at all. It's also not very pretty.

In the future we might have a pointer from encoder to the child device,
which would make the child device list query here so much more sensible.

v3:
- use crtc_state instead of pipe_config
- return true by default from intel_bios_get_dsc_params()
- expand the comment about rc_buffer_block_size and rc_buffer_size

v2:
- make more robust, debug log errors better

[PATCH v3 04/13] drm/i915/dsc: move DP specific compute params to intel_dp.c

[Jani Nikula]

Turns out future DSI specific parameters aren't workable with the
approach of having the encoder specific functions in intel_vdsc.c. Make
intel_dsc_compute_params() a helper that does the encoder independent
parts, and have encoder code call it. Move intel_dsc_dp_compute_params()
to intel_dp.c as intel_dp_dsc_compute_params().

No functional changes.

v2: Rename pipe_config to crtc_state while at it.

[PATCH v3 05/13] drm/i915/dsc: move slice height calculation to encoder

Turns out this isn't compatible with DSI, where we use the value from
VBT. No functional changes.

[PATCH v3 06/13] drm/i915/dsc: add support for computing and writing PPS for DSI encoders

[Jani Nikula]

Add DSI specific computation and transmission to display of PPS.

With hopes that this approach will work for both DP and DSI encoders.

[PATCH v3 09/13] drm/i915/dsi: use afe_clk() instead of intel_dsi_bitrate()

[Jani Nikula]

We'll be expanding afe_clk() to take DSC into account. Switch to using
it where DSC matters. Which is really everywhere that
intel_dsi_bitrate() is currently used in ICL DSI code.

The functional difference is that we round the result closest instead of
down.

[Intel-gfx] [PATCH v3 11/13] drm/i915/dsi: use compressed pixel format with DSC

[Jani Nikula]

When compression is enabled, configure the DSI transcoder to use
compressed format.

[PATCH v3 12/13] drm/i915/dsi: account for DSC in horizontal timings

[Jani Nikula]

When DSC is enabled, we need to adjust the horizontal timings to account
for the compressed (and therefore reduced) link speed.

The compressed frequency ratio simplifies down to the ratio between
compressed and non-compressed bpp.

[PATCH v3 13/13] drm/i915/dsi: add support for DSC

[Jani Nikula]

Enable DSC for DSI, if specified in VBT.

This still lacks DSC aware get config implementation, and therefore
state checker will fail. Also mode valid is not there yet.

v4:
- convert_rgb = true (Vandita)
- ignore max cdclock check (Vandita)
- rename pipe_config to crtc_state

v3:
- take compressed bpp into account

v2:
- Nuke conn_state->max_requested_bpc, it's not used on DSI

Slightly out of scope of this patch, but I see that while configuring PPS9, we are using direct macros and not using anything from
vdsc_cfg->rc_model_size and we have not initialized vdsc_cfg-> rc_edge_factor

Other than that, this patch LGTM.

Other than that, this patch looks good to me.

As mentioned on IRC, we'll need to fix this also for DP I think, and
that's indeed slightly out of scope here.

No, this is for the pipe which is different from what goes on the DSI.

In theory, yes, but I'm doubtful we'll be able to get anything on screen
if VBT says DSC is required and it fails somehow.
