[Intel-gfx] [CI 01/19] drm/i915/xelpd: Handle new location of outputs D and E

[Matt Roper]

The DDI naming template for display version 12 went A-C, TC1-TC6.  With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.

The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously.  The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.

For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value.  However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth).  We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.

v2:
 - Update handling of TGL_TRANS_CLK_SEL_PORT.  (Jose)

v3:
 - Add hpd_pin to handle outputs D and E (Jose)
 - Fixed conversion of BIOS port to aux ch for TC ports (Jose)

[Intel-gfx] [CI 02/19] drm/i915/xelpd: Increase maximum watermark lines to 255

[Matt Roper]

XE_LPD continues to use the same "skylake-style" watermark
programming as other recent platforms.  The only change to the watermark
calculations compared to Display12 is that XE_LPD now allows a
maximum of 255 lines vs the old limit of 31.

Due to the larger possible lines value, the corresponding bits
representing the value in PLANE_WM are also extended, so make sure we
read/write enough bits.  Let's also take this opportunity to switch over
to the REG_FIELD notation.

[Intel-gfx] [CI 04/19] drm/i915/xelpd: Support DP1.4 compression BPPs

[Matt Roper]

From: Vandita Kulkarni <vandita.kulkarni@intel.com>

Support compression BPPs from bpc to uncompressed BPP -1.
So far we have 8,10,12 as valid compressed BPPS now the
support is extended.

[Intel-gfx] [CI 07/19] drm/i915/adl_p: Extend PLANE_WM bits for blocks & lines

[Matt Roper]

ADL-P further extends the bits in PLANE_WM that represent blocks and
lines; we need to extend our masks accordingly.  Since these bits are
reserved and MBZ on earlier platforms, it's safe to use the larger
bitmask on all platforms.

[Matt Roper]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

ADL-P has 3 possible refclk frequencies: 19.2MHz,
24MHz and 38.4MHz

While we're at it, remove the drm_WARNs.  They've never actually helped
us catch any problems, but it's very easy to forget to update them
properly for new platforms.

[Intel-gfx] [CI 09/19] drm/i915/display/tc: Rename safe_mode functions ownership

[Matt Roper]

From: José Roberto de Souza <jose.souza@intel.com>

When DP_PHY_MODE_STATUS_NOT_SAFE is set, it means that display
has the control over the TC phy.
The "not safe" naming is confusing using ownership make it easier
to read also future platforms will have a new register that does the
same job as DP_PHY_MODE_STATUS_NOT_SAFE but with the onwership name.

[Matt Roper]

From: José Roberto de Souza <jose.souza@intel.com>

Alderlake P have modular FIA like TGL but it is always modular in all
skus, not like TGL that we had to read a register to check if it is
monolithic or modular.

CI history only shows this being run a single time since CI_DRM_10065,
and the single run (IGT_6084) was a failure.  The failure looks to be
the same as https://gitlab.freedesktop.org/drm/intel/-/issues/3476 which
is reported against another subtest of the same test.

Both of these appear to be

Some type of GPU hang on a GLK GEM test.  Not related to this ADL-P
series.

Log seems to cut off mid-stream.  Abrupt machine crash or network loss?
Regardless, this test wouldn't be impacted by this series.

None of the failures reported here are due to this series.  Series
applied to di-n with trivial whitespace tweaks reported by checkpatch.

I was looking at the changes here due to a static checker complaint, and
I think there are a number of issues here. Some more serious than
others, and some predate the patch.

Comments inline.

Naming. Basically for any new function, the function name prefix should
match the file name. intel_vdsc.[ch] should have functions prefixed
intel_vdsc_*(). This is where we're headed to increase clarity.

intel_uncompressed_*() is something completely different. 

Granted, here we already have intel_dsc_*() in intel_vdsc.c. We should
probably stick with intel_dsc_*(). A possible function or file rename is
not out of the question, but that's a separate matter.

This fails to disable compression if we only have compression but no
bigjoiner, which is the more common case!

Nitpick: This duplicates a bunch of logic for figuring out master/slave.

The static checker warning was about crtc->pipe + 1 usage. Since
INTEL_NUM_PIPES() looks at the hamming weight of i915->pipe_mask, the
checker has a hard time figuring out it does not overflow
i915->pipe_to_crtc_mapping[] in intel_get_crtc_for_pipe().

So here in intel_vdsc.c the checks are for overflowing/underflowing the
pipe range. In intel_get_crtc_for_pipe() there's a check for the pipe
actually existing - the pipe numbering might not be contiguous.

Superficially the static checker warning is bogus, as in we won't
overflow anything. However, deep down there are issues in the
consistency of the checks and how to handle non-contigouous pipe
numbering.

Indeed, this does not *need* the number. We should figure out the next
*crtc*, not the next pipe *number*, which may or may not be pipe + 1.

I don't think we should add these checks here. Make sure the crtc_state
only has the relevant stuff enabled if the platform supports it. Don't
duplicate the checks.

As this is always called after intel_dsc_enable(), I think it would make

You can't read this without holding the power domain.

Since this is always called after intel_dsc_get_config(), I think it
would make sense to move this reading there.

As there is not separate register for uncompressed joiner, using bitfield of dsc register only the function name can be changed to intel_dsc_uncompressed_joiner_enable().

We may need to remove both the condition check.
In uncompressed bigjoiner, compression_enable flag will be 0 and may not clear the bit of dss_ctl1_reg.
So can we remove both the checks, hoping it will not harm reseting the register even if it is not set.

dss_ctl1 value is used to identify master or slave crtc. If needed WARN_ON check can be removed... but pipe enum values like PIPE_A/B/C/D is used to get the master/slave crtc and always bigjoiner is possible with two adjacent pipes.

Ok.
Earlier the plan is to have separate functions for uncompressed joiner, but as you suggested it can be done in the same functions of compressed bigjoiner code.
Thanks Jani for review.

Now it only disables if *both* were enabled. It needs to be disabled if
*either* was enabled. But if *neither* was enabled, we don't need to do
this.

I sent the patch for this and you reviewed it... but are adjacent pipes
a requirement for bigjoiner? Would e.g. A+C work if B was fused off? If
not, my patch 2/2 is incorrect.

@Jani I had asked to create a separate joiner enable since having an uncompressed enable inside dsc_enable
just from the names makes it contradicting.
But sure may be with a comment before calling uncompressed_joiner_enable() it can be just called from inside dsc enable()
And instead of checking the display ver there we just use this condition:
if (crtc_state->bigjoiner && !crtc_state->dsc.compression_enable) {
	intel_uncompressed_joiner_enable(crtc_state);
	}
Since the atomic check ensures that only for ver >=13 is when we allow big joiner and no DSC combination.

Animesh, Jani does that sound good?

Yes.

Regarding naming semantics, I think we just need to consider DSC an
engine that does other things than just compression. The actual
registers being the same makes, I think, the logic harder to follow with
these being separate steps. Also, you can then cover them with a single
power domain get/put.

Anyway, care must be taken to not change the logic for compressed paths.

BR,
Jani.
