The IO buffer Wake and Fast Wake bit size and value have been changed from
Gen12+. It programs the default value of IO buffer Wake and Fast Wake on
Gen12+. It adds definitions of IO buffer Wake and Fast Wake for pre Gen12
and Gen12+. And it aligns PSR2 definition macros.
v2: Fix macro definitions. (José)
v3: Addressed review comments from José
- Add missing default values of IO_BUFFER_WAKE and FAST_WAKE for GEN9+
- Change a style of macro naming in order to use lines as input.
- Update Todo comments.
v4: Add parentheses to macros to avoid precedence issues.

As a last minute addition, I added an assertion to make sure that the
new i915_vma view would be equal to the discard. However, the positive
encouragement from CI only goes to show that we rarely take this path,
and it wasn't until the post-merge run did we hit the assert -- because
it compared the wrong view. Fixup the copy'n'paste error and compare
against both the old view and the expected new view.

Across the many users of the GGTT vma (internal objects, mmapings,
display etc), we may end up with conflicting requirements for the
placement. Currently, we try to resolve the conflict by unbinding the
vma and rebinding it to match the new constraints; over time we will end
up with a GGTT that matches the most strict constraints over all
concurrent users. However, this causes a problem if the vma is currently
in use as we must wait until it is idle before moving it. But there is
no restriction on the number of views we may use (apart from the limited
size of the GGTT itself), and so if the active vma does not meet our
requirements, try and build a new one!

This patch adds support for Kaohsiung Opto-Electronics Inc.
10.1" TX26D202VM0BWA WUXGA(1920x1200) TFT LCD panel with LVDS interface.
The panel has dual LVDS channels.
My panel is manufactured by US Micro Products(USMP). There is a tag at
the back of the panel, which indicates the panel type is 'TX26D202VM0BWA'
and it's made by KOE in Taiwan.
The panel spec from USMP can be found at:
https://www.usmicroproducts.com/sites/default/files/datasheets/USMP-T101-192120NDU-A0.pdf
The below panel spec from KOE is basically the same to the one from USMP.
However, the panel type 'TX26D202VM0BAA' is a little bit different.
It looks that the two types of panel are compatible with each other.

Reduce the 3 relocation paths down to the single path that accommodates
all. The primary motivation for this is to guard the relocations with a
natural fence (derived from the i915_request used to write the
relocation from the GPU).
The tradeoff in using async gpu relocations is that it increases latency
over using direct CPU relocations, for the cases where the target is
idle and accessible by the CPU. The benefit is greatly reduced lock
contention and improved concurrency by pipelining.
Note that forcing the async gpu relocations does reveal a few issues
they have. Firstly, is that they are visible as writes to gem_busy,
causing to mark some buffers are being to written to by the GPU even
though userspace only reads. Secondly is that, in combination with the
cmdparser, they can cause priority inversions. This should be the case
where the work is being put into a common workqueue losing our priority
information and so being executed in FIFO from the worker, denying us
the opportunity to reorder the requests afterwards.

RKL doesn't have PSR2 HW tracking, it was replaced by software/manual
tracking. The driver is required to track the areas that needs update
and program hardware to send selective updates.
So until the software tracking is implemented, PSR2 needs to be disabled
for platforms without PSR2 HW tracking.

There are a couple places in our driver that loop over transcoders A..D
for gen11+; since RKL only has three pipes/transcoders, this can lead to
unclaimed register reads/writes. We should add checks for transcoder
existence where appropriate.
v2: Move one transcoder check that wound up in the wrong function after
conflict resolution. It belongs in bdw_get_trans_port_sync_config
rather than bxt_get_dsi_transcoder_state.
v3: Switch loops to use for_each_cpu_transcoder_masked() since this
iterator already checks the platform's transcoder mask for us.

Previous patch didn't take into account all pipes
but only those in state, which could cause wrong
CDCLK conclcusions and calculations.
Also there was a severe issue with min_cdclk being
assigned to 0 every compare cycle.
Too bad this was found by me only after merge.
This could be also causing the issues in test, however
not clear - anyway marking this as fixing the
"Adjust CDCLK accordingly to our DBuf bw needs".
v2: - s/pipe/crtc->pipe/
- save a bit of instructions by
skipping inactive pipes, without

RKL uses the DDI A, DDI B, DDI USBC1, DDI USBC2 from the DE point of
view, so all DDI/pipe/transcoder register use these indexes to refer to
them. Combo phy and IO functions follow another namespace that we keep
as "enum phy". The VBT in theory would use the DE point of view, but
that does not happen in practice.
Provide a table to convert the child devices to the "correct" port
numbering we use. Now this is the output we get while reading the VBT:

Use the plain msec_to_jiffies() rather than the _timeout variant so we
round down and do not add an extra jiffy to our interval. For example,
with timeslicing we do not want to err on the longer side as any
fairness depends on catching hogging contexts on the GPU. Bring on
CFS.

If the execbuf is interrupted after building the cmdparser pipeline, and
before we commit to submitting the request to HW, we would attempt to
clean up the cmdparser early. While we held active references to the vma
being parsed and constructed, we did not hold an active reference for
the buffer pool itself. The result was that an interrupted execbuf could
still have run the cmdparser pipeline, but since the buffer pool was
idle, its target vma could have been recycled.
Note this problem only occurs if the cmdparser is running async due to
pipelined waits on busy fences, and the execbuf is interrupted.

The most innocuous result of not having done this is that we end up
sending unnecessary methods when we next enable the window.
However, interactions with the code handling skipping disables when
an update immediately follows, and window ownership assignment, can
lead to upsetting the display hardware on Volta and newer.

Since GM200, SORs are no longer tied to a specific connector, and we
allocate them instead, with the assumption that all SORs are equally
capable.
However, there's a 1<->1 mapping between SOR and HDA pin widget, and
it turns out that it's possible for some widgets to be disabled...
In order to avoid picking a SOR without a valid pin widget, some new
rules need to be added.

Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA),
using the categorization from [1]. That means that it's time to convert
the get_user_pages*() + put_page() calls to pin_user_pages*() +
unpin_user_pages() calls.
There is some helpful background in [2]: basically, this is a small part
of fixing a long-standing disconnect between pinning pages, and file
systems' use of those pages.

[Why]
Whenever we switch between tiled formats without also switching pixel
formats or doing anything else that recreates the DC plane state we
can run into underflow or hangs since we're not updating the
DML parameters before committing to the hardware.
[How]
If the update type is FULL then call validate_bandwidth again to update
the DML parmeters before committing the state.
This is basically just a workaround and protective measure against
update types being added DC where we could run into this issue in
the future.
We can only fully validate the state in advance before applying it to
the hardware if we recreate all the plane and stream states since
we can't modify what's currently in use.
The next step is to update DM to ensure that we're creating the plane
and stream states for whatever could potentially be a full update in
DC to pre-emptively recreate the state for DC global validation.
The workaround can stay until this has been fixed in DM.

We may end up with no planes set yet, depending on the ordering, but we
should have the proper blanking state which is either handled by either
DPG or TG depending on the hardware generation. Check both to determine
the proper blanked state.
