When any other value than EDP_PSR_TP4_TIME_0US is set, TPS1 and TPS4
will be used to do the link training when exiting PSR1.
Happily the eDP panels tested so far was able to sync with source
even without HBR3/TPS4 support but let use the right training
pattern.
TPS4 support was added to PSR1 registers because HBR3/PSR
specification was not closed when ICL was freezed so if HBR3 was
supported by PSR, ICL would already be ready but it was not added to
specification so lets always disable TPS4.

In order to make it easier to bring up new platforms
without having to take care about all corner cases
that was previously taken care for previous platforms
we already use comparative INTEL_GEN statements.
Let's start doing the same with PCH.
The only caveats are:
- less-than comparisons need to be avoided or done with
attention and check > PCH_NONE as well.
- It is not necessarily a chronological order, but a matter
of south display compatibility/inheritance.

This exactly same approach was already used from gen9

for gen11+.
Let's first assume that we inherit a similar platform

Different from the previous attempts this will be
done this time with coccinelle. We obviously need to
exclude some case that is really exclusive for gen11

Considering the fact that some of the AFBC specific pixel formats are expressed
in bits per pixel (ie bpp which is not byte aligned), the pitch (ie width * bpp)
is not guaranteed to be aligned to burst size (ie 8 or 16 bytes).
For example, DRM_FORMAT_VUY101010 is 30 bits per pixel. For a framebuffer of
width 32 pixels, the pitch will be 120 bytes which is not aligned to burst size
(ie 16 bytes) for DP650.

The newly supported AFBC YUV formats have the following rotation memory
constraints (in DP550/DP650).
1. DRM_FORMAT_VUY888/DRM_FORMAT_VUY101010 :- It can rotate upto 8
horizontal lines in the AFBC output buffer.
2. DRM_FORMAT_YUV420_8BIT :- It can rotate upto 16 horizontal lines
in the AFBC output buffer.
Also some of the pixel formats are specified in bits per pixel (rather
than bytes per pixel), so the calculation needs to take note of this.
Besides there are some difference between DP550 and DP650 and these are
as follows:-
1. DRM_FORMAT_X0L2 (in uncompressed format) does not support rotation in
DP550. For DP650, it can rotate upto 16 horizontal lines in the AFBC
output buffer, whereas in DP550 (with AFBC), it can rotate upto 8
horizontal lines.
2. DRM_FORMAT_YUV420_10BIT :- It can rotate upto 8 horizontal lines in
dp550 and 16 horizontal lines in DP650.

We need to define a common list of format modifiers supported by each of
the Mali display processors.
The following are the constraints with AFBC:-
1. AFBC is not supported for the formats defined in
malidp_hw_format_is_linear_only()
2. Some of the formats are supported only with AFBC modifiers. Thus we have
introduced a new function 'malidp_hw_format_is_afbc_only()' which verifies
the same.
3. AFBC_FORMAT_MOD_YTR needs to be provided for any RGB format.
4. Formats <= 16bpp cannot support AFBC_FORMAT_MOD_SPLIT.
5. CBR should not be set for non-subsampled formats.
6. SMART layer does not support framebuffer with AFBC modifiers.
Return -EINVAL for such a scenario.
7. AFBC_FORMAT_MOD_YTR is not supported for any YUV formats.
8. Formats which are subsampled cannot support AFBC_FORMAT_MOD_SPLIT.
However in DP550, YUV_420_10BIT is supported with AFBC_FORMAT_MOD_SPLIT.
This feature has been identified with
MALIDP_DEVICE_AFBC_YUV_420_10_SUPPORT_SPLIT.
9. In DP550 and DP650, for YUYV, the hardware supports different
format-ids to be used with and without AFBC modifier. We have used the
feature 'MALIDP_DEVICE_AFBC_YUYV_USE_422_P2' to identify this
characteristic.
10. DP500 does not support split mode (ie AFBC_FORMAT_MOD_SPLIT). We have
used the feature 'MALIDP_DEVICE_AFBC_SUPPORT_SPLIT' to identify the DPs
which support SPLIT mode.
11. DP550 supports YUV420 with split mode. We have defined the feature
'AFBC_SUPPORT_SPLIT_WITH_YUV_420_10' to identify this characteristic.

Added the AFBC decoder registers for DP500 , DP550 and DP650.
These registers control the processing of AFBC buffers. It controls various
features like AFBC decoder enable, lossless transformation and block split
as well as setting of the left, right, top and bottom cropping of AFBC
buffers (in number of pixels).
All the layers (except DE_SMART) support framebuffers with AFBC modifiers.
One needs to set the pixel values of the top, left, bottom and right
cropping for the AFBC framebuffer.
Cropping an AFBC framebuffer is controlled by the AFBC crop registers.
In that case, the layer input size registers should be configured with
framebuffer's dimensions and not with drm_plane_state source width/height
values (which is used for non AFBC framebuffer to denote cropping).
Changes from v1:
- Removed the "if (fb->modifier)" check from malidp_de_plane_update()
and added it in malidp_de_set_plane_afbc(). This will consolidate all the
AFBC specific register configurations in a single function ie
malidp_de_set_plane_afbc().

As we look to enable AFBC using DRM format modifiers, we run into
problems which we've historically handled via vendor-private details
(i.e. gralloc, on Android).
AFBC (as an encoding) is fully flexible, and for example YUV data can
be encoded into 1, 2 or 3 encoded "planes", much like the linear
equivalents. Component order is also meaningful, as AFBC doesn't
necessarily care about what each "channel" of the data it encodes
contains. Therefore ABGR8888 and RGBA8888 can be encoded in AFBC with
different representations. Similarly, 'X' components may be encoded
into AFBC streams in cases where a decoder expects to decode a 4th
component.
In addition, AFBC is a licensable IP, meaning that to support the
ecosystem we need to ensure that _all_ AFBC users are able to describe
the encodings that they need. This is much better achieved by
preserving meaning in the fourcc codes when they are combined with an
AFBC modifier.
In essence, we want to use the modifier to describe the parameters of
the AFBC encode/decode, and use the fourcc code to describe the data
being encoded/decoded.
To do anything different would be to introduce redundancy - we would
need to duplicate in the modifier information which is _already_
conveyed clearly and non-ambigiously by a fourcc code.
I hope that for RGB this is non-controversial.
(BGRA8888 + MODIFIER_AFBC) is a different format from
(RGBA8888 + MODIFIER_AFBC).
Possibly more controversial is that (XBGR8888 + MODIFIER_AFBC)
is different from (BGR888 + MODIFIER_AFBC). I understand that in some
schemes it is not the case - but in AFBC it is so.
Where we run into problems is where there are not already fourcc codes
which represent the data which the AFBC encoder/decoder is processing.
To that end, we want to introduce new fourcc codes to describe the
data being encoded/decoded, in the places where none of the existing
fourcc codes are applicable.
Where we don't support an equivalent non-compressed layout, or where
no "obvious" linear layout exists, we are proposing adding fourcc
codes which have no associated linear layout - because any layout we
proposed would be completely arbitrary.
Some formats are following the naming conventions from [2].
The summary of the new formats is:
DRM_FORMAT_VUY888 - Packed 8-bit YUV 444. Y followed by U then V.
DRM_FORMAT_VUY101010 - Packed 10-bit YUV 444. Y followed by U then
V. No defined linear encoding.
DRM_FORMAT_Y210 - Packed 10-bit YUV 422. Y followed by U (then Y)
then V. 10-bit samples in 16-bit words.
DRM_FORMAT_Y410 - Packed 10-bit YUV 444, with 2-bit alpha.
DRM_FORMAT_P210 - Semi-planar 10-bit YUV 422. Y plane, followed by
interleaved U-then-V plane. 10-bit samples in
16-bit words.
DRM_FORMAT_YUV420_8BIT - Packed 8-bit YUV 420. Y followed by U then
V. No defined linear encoding
DRM_FORMAT_YUV420_10BIT - Packed 10-bit YUV 420. Y followed by U
then V. No defined linear encoding
Please also note that in the absence of AFBC, we would still need to
add Y410, Y210 and P210.
Full rationale follows:
YUV 444 8-bit, 1-plane
----------------------
The currently defined AYUV format encodes a 4th alpha component,
which makes it unsuitable for representing a 3-component YUV 444
AFBC stream.
The proposed[1] XYUV format which is supported by Mali-DP in linear
layout is also unsuitable, because the component order is the
opposite of the AFBC version, and it encodes a 4th 'X' component.
DRM_FORMAT_VUY888 is the "obvious" format for a 3-component, packed,
YUV 444 8-bit format, with the component order which our HW expects to
encode/decode. It conforms to the same naming convention as the
existing packed YUV 444 format.
The naming here is meant to be consistent with DRM_FORMAT_AYUV and
DRM_FORMAT_XYUV[1]
YUV 444 10-bit, 1-plane
-----------------------
There is no currently-defined YUV 444 10-bit format in
drm_fourcc.h, irrespective of number of planes.
The proposed[1] XVYU2101010 format which is supported by Mali-DP in
linear layout uses the wrong component order, and also encodes a 4th
'X' component, which doesn't match the AFBC version of YUV 444
10-bit which we support.
DRM_FORMAT_Y410 is the same layout as XVYU2101010, but with 2 bits of
alpha. This format is supported with linear layout by Mali GPUs. The
naming follows[2].
There is no "obvious" linear encoding for a 3-component 10:10:10
packed format, and so DRM_FORMAT_VUY101010 defines a component
order, but not a bit encoding. Again, the naming is meant to be
consistent with DRM_FORMAT_AYUV.
YUV 422 8-bit, 1-plane
----------------------
The existing DRM_FORMAT_YUYV (and the other component orders) are
single-planar YUV 422 8-bit formats. Following the convention of
the component orders of the RGB formats, YUYV has the correct
component order for our AFBC encoding (Y followed by U followed by
V). We can use YUYV for AFBC YUV 422 8-bit.
YUV 422 10-bit, 1-plane
-----------------------
There is no currently-defined YUV 422 10-bit format in drm_fourcc.h
DRM_FORMAT_Y210 is analogous to YUYV, but with 10-bits per sample
packed into the upper 10-bits of 16-bit samples. This format is
supported in both linear and AFBC by Mali GPUs.
YUV 422 10-bit, 2-plane
-----------------------
The recently defined DRM_FORMAT_P010 format is a 10-bit semi-planar
YUV 420 format, which has the correct component ordering for an AFBC
2-plane YUV 420 buffer. The linear layout contains meaningless padding
bits, which will not be encoded in an AFBC stream.
YUV 420 8-bit, 1-plane
----------------------
There is no currently defined single-planar YUV 420, 8-bit format
in drm_fourcc.h. There's differing opinions on whether using the
existing fourcc-implied n_planes where possible is a good idea or
not when using modifiers.
For me, it's much more "obvious" to use NV12 for 2-plane AFBC and
YUV420 for 3-plane AFBC. This keeps the aforementioned separation
between the AFBC codec settings (in the modifier) and the pixel data
format (in the fourcc). With different vendors using AFBC, this helps
to ensure that there is no confusion in interoperation. It also
ensures that the AFBC modifiers describe AFBC itself (which is a
licensable component), and not implementation details which are not
defined by AFBC.
The proposed[1] X0L0 format which Mali-DP supports with Linear layout
is unsuitable, as it contains a 4th 'X' component, and our AFBC
decoder expects only 3 components.
To that end, we propose a new YUV 420 8-bit format. There is no
"obvious" linear encoding for a 3-component 8:8:8, 420, packed format,
and so DRM_FORMAT_YUV420_8BIT defines a component order, but not a
bit encoding. I'm happy to hear different naming suggestions.
YUV 420 8-bit, 2-, 3-plane
--------------------------
These already exist, we can use NV12 and YUV420.
YUV 420 10-bit, 1-plane
-----------------------
As above, no current definition exists, and X0L2 encodes a 4th 'X'
channel.
Analogous to DRM_FORMAT_YUV420_8BIT, we define DRM_FORMAT_YUV420_10BIT.

No compatible string for it yet, just the version-dependent changes.
They've now tied the hub and the core interrupt lines into a single
interrupt line coming out of the block. It also turns out I made a
mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
itself -- the bridge is going away in favor of an external reset
controller in a larger HW module.
v2: Use consistent checks for whether we're on 4.2, and fix a leak in
an error path.
v3: Use more general means of determining if the current 4.2 changes
are in place, as apparently other platforms may switch back (noted
by Dave). Update the binding doc.
v4: Improve error handling for IRQ init.

It is debatable whether having an error message on suspend for forcibly
cancelling outstanding work is worthwhile. We want to know if it occurs
in the wild (as we will then have to reconsider the approach!), but
equally is not fatal across suspend, as upon resume we automatically
clear the wedged status.
However, CI does trigger this scenario with gem_eio/suspend; as there we
are intentionally wedging the device upon suspend. The dilemma is how
not to trigger a failure report for the dmesg spam, for which the
quickest response is to suppress the warning in the kernel. I'd rather
mark it as accepted in gem_eio, but for now detecting when gem_eio is
playing games and cancelling the warning for that case seems a barely
acceptable hack.
