[PATCH v3 01/16] drm/mst: remove mgr parameter and debug logging from drm_dp_get_vc_payload_bw()

[Jani Nikula]

The struct drm_dp_mst_topology_mgr *mgr parameter is only used for debug
logging in case the passed in link rate or lane count are zero. There's
no further error checking as such, and the function returns 0.

There should be no case where the parameters are zero. The returned
value is generally used as a divisor, and if we were hitting this, we'd
be seeing division by zero.

Just remove the debug logging altogether, along with the mgr parameter,
so that the function can be used in non-MST contexts without the
topology manager.

v2: Also remove drm_dp_mst_helper_tests_init as unnecessary (Imre)

[PATCH v3 04/16] drm/i915/mst: change return value of mst_stream_find_vcpi_slots_for_bpp()

[Jani Nikula]

The callers of mst_stream_find_vcpi_slots_for_bpp() don't need the
returned slots for anything. On the contrary, they need to jump through
hoops to just distinguish between success and failure. Just return 0
instead of slots from mst_stream_find_vcpi_slots_for_bpp() for success,
and simplify the callers.

There's a pointless ret local variable that we can drop in the process.

easier to adapt to 128b/132b SST.

[PATCH v3 07/16] drm/i915/mst: adapt intel_dp_mtp_tu_compute_config() for 128b/132b SST

[Jani Nikula]

Handle 128b/132b SST in intel_dp_mtp_tu_compute_config(). The remote
bandwidth overhead and time slot allocation are only relevant for MST;
SST only needs the local bandwidth and a check that 64 slots isn't
exceeded.

[PATCH v3 13/16] drm/i915/ddi: start distinguishing 128b/132b SST and MST at state readout

[Jani Nikula]

We'll want to distinguish 128b/132b SST and MST modes at state
readout. There's a catch, though. From the hardware perspective,
128b/132b SST and MST programming are pretty much the same. And we can't
really ask the sink at this point.

If we have more than one transcoder in 128b/132b mode associated with
the port, we can safely assume it's MST. But for MST with only a single
stream enabled, we are pretty much out of luck. Let's fall back to
looking at the software state, i.e. intel_dp->is_mst. It should be fine
for the state checker, but for hardware takeover at probe, we'll have to
trust the GOP has only enabled SST.

TODO: Not sure how this *or* our current code handles 128b/132b enabled
by GOP.

[PATCH v3 16/16] drm/i915/dp: compute config for 128b/132b SST w/o DSC

[Jani Nikula]

Enable basic 128b/132b SST functionality without compression. Reuse
intel_dp_mtp_tu_compute_config() to figure out the TU after we've
determined we need to use an UHBR rate.

It's slightly complicated as the M/N computation is done in different
places in MST and SST paths, so we need to avoid trashing the values
later for UHBR.

If uncompressed UHBR fails, we drop to compressed non-UHBR, which is
quite likely to fail as well. We still lack 128b/132b SST+DSC.

We need mst_master_transcoder also for 128b/132b SST. Use cpu_transcoder
directly. Enhanced framing is "don't care" for 128b/132b link.

v2: mst_master_transcoder, enhanced framing (Imre)

[PATCH] drm/i915/ddi: write payload for 128b/132b SST

[Jani Nikula]

Write the payload allocation table for 128b/132b SST. Use VCPID 1 and
start from slot 0, with dp_m_n.tu slots.

This is preparation for enabling 128b/132b SST. This path is not
reachable yet. Indeed, we don't yet compute TU for 128b/132b SST.

v2: Handle drm_dp_dpcd_write_payload() failures (Imre)

v3: Include drm_dp_helper.h (kernel test robot)
