kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

Notify drm core before sending pending events during crtc disable.
This fixes the first event after disable having an old stale timestamp
by having drm_crtc_vblank_off update the timestamp to now.
This was seen while debugging weston log message:
Warning: computed repaint delay is insane: -8212 msec
This occurred due to:
1. driver starts up
2. fbcon comes along and restores fbdev, enabling vblank
3. vblank_disable_fn fires via timer disabling vblank, keeping vblank
seq number and time set at current value
(some time later)
4. weston starts and does a modeset
5. atomic commit disables crtc while it does the modeset
6. ipu_crtc_atomic_disable sends vblank with old seq number and time

rebase the other patches on top of that
- fold the hmm_devmem_add_resource into the DEVICE_PUBLIC memory removal
patch
- remove _vm_normal_page as it isn't needed without DEVICE_PUBLIC memory
- pick up various ACKs
Changes since v2:
- fix nvdimm kunit build
- add a new memory type for device dax
- fix a few issues in intermediate patches that didn't show up in the end
result
- incorporate feedback from Michal Hocko, including killing of

- rebase
- also switch p2pdma to the internal refcount
- add type checking for pgmap->type
- rename the migrate method to migrate_to_ram
- cleanup the altmap_valid flag

Despite what I think the prm recommends, commit f2253bd985
("drm/i915/ringbuffer: EMIT_INVALIDATE after switch context") turned out
to be a huge mistake when enabling Ironlake contexts as the GPU would
hang on either a MI_FLUSH or PIPE_CONTROL immediately following the
MI_SET_CONTEXT of an active mesa context (more vanilla contexts, e.g.
simple rendercopies with igt, do not suffer).
Ville found the following clue,
"[DevCTG+]: For the invalidate operation of the pipe control, the
following pointers are affected. The
invalidate operation affects the restore of these packets. If the pipe
control invalidate operation is completed
before the context save, the indirect pointers will not be restored from
memory.
1. Pipeline State Pointer
2. Media State Pointer
3. Constant Buffer Packet"
which suggests by us emitting the INVALIDATE prior to the MI_SET_CONTEXT,
we prevent the context-restore from chasing the dangling pointers within
the image, and explains why this likely prevents the GPU hang.

When using an I2S source using a different clock source (usually the I2S
audio HW uses dedicated PLLs, different from the HDMI PHY PLL), fixed
CTS values will cause some frequent audio drop-out and glitches as
reported on Amlogic, Allwinner and Rockchip SoCs setups.
Setting the CTS in automatic mode will let the HDMI controller generate
automatically the CTS value to match the input audio clock.
The DesignWare DW-HDMI User Guide explains:
For Automatic CTS generation
Write "0" on the bit field "CTS_manual", Register 0x3205: AUD_CTS3
The DesignWare DW-HDMI Databook explains :
If "CTS_manual" bit equals 0b this registers contains "audCTS[19:0]"
generated by the Cycle time counter according to specified timing.

In contrast to all of the DSI panel drivers in drivers/gpu/drm/panel
which attach to the DSI host via mipi_dsi_attach() at probe time, the
ADV7533 bridge device does not. Instead it defers this to the point that
the upstream device connects to its bridge via drm_bridge_attach().
The generic Synopsys MIPI DSI host driver does not register it's own
drm_bridge until the MIPI DSI has attached. But it does not call
drm_bridge_attach() on the downstream device until the upstream device
has attached. This leads to a chicken and the egg failure and the DRM
pipeline does not complete.
Since all other mipi_dsi_device drivers call mipi_dsi_attach() in
probe(), make the adv7533 mipi_dsi_device do the same. This ensures that
the Synopsys MIPI DSI host registers it's bridge such that it is
available for the upstream device to connect to.

commit 6c6de1c9e2 ("ASoC: vc4: vc4_hdmi: don't select unnecessary
Platform")
Current ALSA SoC avoid to add duplicate component to rtd,
and this driver was selecting CPU component as Platform component.
Thus, above patch removed Platform settings from this driver,
because it assumed these are same component.
But, some CPU driver is using generic DMAEngine, in such case, both
CPU component and Platform component will have same of_node/name.
In other words, there are some components which are different but
have same of_node/name.
In such case, Card driver definitely need to select Platform even
though it is same as CPU.
It is depends on CPU driver, but is difficult to know it from Card driver.
This patch reverts above patch.

Add COMPILE_TEST dependency to force exynos driver to
built for more than arm and to built modules
that otherwise required other symbols to be de-selected.
This will increase build coverage of the exynos driver
thus allowing most trivial build errors to be detected/fixed early.
This introduces one warning when built using sh:
exynos7_drm_decon.c: In function ‘decon_remove’:
exynos7_drm_decon.c:769:24: warning: unused variable ‘ctx’
struct decon_context *ctx = dev_get_drvdata(&pdev->dev);
This is due to the definition of iounmap() in sh,
and nothing that exynos driver can fix.
Include fix of exynos build for alpha.

According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.

Simplify AUX data write by dropping index arithmetic and shifting and
replacing it with a call to a helper function that does two things:
1. Copies user-provided data into a write buffer
2. Transfers contents of the write buffer to up to 4 32-bit
registers on the chip
Note that separate data endianness fix:
tmp = (tmp << 8) | buf[i];
that was reserved for DP_AUX_I2C_WRITE looks really strange, since it
will place data differently depending on the passed user-data
size. E.g. for a write of 1 byte, data transferred to the chip would
look like:
[byte0] [dummy1] [dummy2] [dummy3]
whereas for a write of 4 bytes we'd get:
[byte3] [byte2] [byte1] [byte0]
Since there's no indication in the datasheet that I2C write buffer
should be treated differently than AUX write buffer and no comment in
the original code explaining why it was done this way, that special
I2C write buffer transformation was dropped in this patch.

A very unfortunate aspect of tc_write()/tc_read() macro helpers is
that they capture quite a bit of context around them and thus require
the caller to have magic variables 'ret' and 'tc' as well as label
'err'. That makes a number of code paths rather counter-intuitive and
somewhat clunky, for example tc_stream_clock_calc() ends up being like
this:
int ret;
tc_write(DP0_VIDMNGEN1, 32768);
return 0;
err:
return ret;
which is rather surprising when you read the code for the first
time. Since those helpers arguably aren't really saving that much code
and there's no way of fixing them without making them too verbose to
be worth it change the driver code to not use them at all.

The crc computation worker needs to be able to get at some data
structures and framebuffer mappings, while potentially more atomic
updates are going on. The solution thus far is to copy relevant bits
around, but that's very tedious.
Here's a new approach, which tries to be more clever, but relies on a
few not-so-obvious things:
- crtc_state is always updated when a plane_state changes. Therefore
we can just stuff plane_state pointers into a crtc_state. That
solves the problem of easily getting at the needed plane_states.
- with the flushing changes from previous patches the above also holds
without races due to the next atomic update being a bit eager with
cleaning up pending work - we always wait for all crc work items to
complete before unmapping framebuffers.
- we also need to make sure that the hrtimer fires off the right
worker. Keep a new distinct crc_state pointer, under the
vkms_output->lock protection for this. Note that crtc->state is
updated very early in the atomic commit, way before we arm the
vblank event - the vblank event should always match the buffers we
use to compute the crc. This also solves an issue in the hrtimer,
where we've accessed drm_crtc->state without holding the right locks
(we held none - oops).
- in the worker itself we can then just access the plane states we
need, again solving a bunch of ordering and locking issues.
Accessing plane->state requires locks, accessing the private
vkms_crtc_state->active_planes pointer only requires that the memory
doesn't get freed too early.
The idea behind vkms_crtc_state->active_planes is that this would
contain all visible planes, in z-order, as a first step towards a more
generic blending implementation.
Note that this patch also fixes races between prepare_fb/cleanup_fb
and the crc worker accessing ->vaddr.

Currently, we flush pending CRC workers very late in the commit flow,
when we destroy all the old crtc states. Unfortunately, at that point,
the framebuffers are already unpinned (and our vaddr possible gone), so
this isn't good. Also, the plane_states we need might also already be
cleaned up, since cleanup order of state structures isn't well defined.
Fix this by waiting for all CRC workers of the old state to complete
before we start any of the cleanup work. For correct ordering and
avoiding races, we can only flush_work after
drm_atomic_helper_wait_for_vblanks() since we know that all subsequent
queue_work will be for the new state. Only once that's done is
flush_work() useful, before that we might flush the work, and then right
after the hrtimer that simulates vblank queues it again. Every time you
have a flush_work before cleaning up the work structure, the following
sequence must be obeyed, or it can go wrong:
1. Make sure no one else can re-queue the work anymore (in our case
that's done by a combination of first updating output->crc_state and
then waiting for the vblank to pass to make sure the hrtimer has noticed
that change).
2. flush_work()
3. Actually clean up stuff (which isn't done here).
Doing the flush_work before we even completed the output->state update,
much less waited for the vblank to make sure that's happened, missed the
point.
Note that this is not yet race-free because of the hrtimer and crc
worker look at the wrong state pointers, but that will be fixed in
subsequent patches.

The worker is always in process context, no need for the _irqsafe
version. Same for the set_source callback, that's only called from the
debugfs handler in a syscall.

The issue we have is that the crc worker might fall behind. We've
tried to handle this by tracking both the earliest frame for which it
still needs to compute a crc, and the last one. Plus when the
crtc_state changes, we have a new work item, which are all run in
order due to the ordered workqueue we allocate for each vkms crtc.
Trouble is there's been a few small issues in the current code:
- we need to capture frame_end in the vblank hrtimer, not in the
worker. The worker might run much later, and then we generate a lot
of crc for which there's already a different worker queued up.
- frame number might be 0, so create a new crc_pending boolean to
track this without confusion.
- we need to atomically grab frame_start/end and clear it, so do that
all in one go. This is not going to create a new race, because if we
race with the hrtimer then our work will be re-run.
- only race that can happen is the following:
1. worker starts
2. hrtimer runs and updates frame_end
3. worker grabs frame_start/end, already reading the new frame_end,
and clears crc_pending
4. hrtimer calls queue_work()
5. worker completes
6. worker gets re-run, crc_pending is false
Explain this case a bit better by rewording the comment.
v2: Demote warning level output to debug when we fail to requeue, this
is expected under high load when the crc worker can't quite keep up.

[Why]
The AVI infoframe is incorrectly programmed on DCN1/2 when enabling a
stream - causing the wrong pixel encoding to be used for display.
This is because the AVI infoframe is programmed before the DIG BE is
connected to the FE and turned on, so enabling the AFMT block doesn't
actually work and the registers subsequently can't be written to.
[How]
Program the infoframe *after* turning on the DIG FE. This was the
behavior previously used but it was incorrectly reverted
when adding the DCN2 HW sequencer code.

If we use the gem fb helper as the prepare_fb hook, plus the
drm_prime.c import helpers now automatically setting obj->resv, we can
use the shared helpers to wait for fences instead of rolling our own.
Note that this relies on mtk setting drm_fb->obj, which is already
done in mtk_drm_framebuffer_init().
Aside: Probably can use the default commit_tail with this again, but I
didn't check for that.

DisplayID blocks allow embedding of CEA blocks. The payloads are
identical to traditional top level CEA extension blocks, but the header
is slightly different.
This change allows the CEA parser to find a CEA block inside a DisplayID
block. Additionally, it adds support for parsing the embedded CTA

The commit 3aeeb13d89 ("drm/modes: Support modes names on the command
line") added name support to the DRM modes, and added that name to the
debug message.
However, that code tests for whether or not the name variable is NULL and
only prints it if it's not. Except that that variable is an array, so it
will never be NULL.
The original intent was to print it only when the name has been specified.
Just printing the array directly will achieve the same thing since the
drm_cmdline_mode structure that holds it is itself contained in
drm_connector, that is allocated with its whole content zero'd.
That means that if the name is not declared, the array will be all zeros,
which will not print anything.

The driver_find_device() accepts a match function pointer to
filter the devices for lookup, similar to bus/class_find_device().
However, there is a minor difference in the prototype for the
match parameter for driver_find_device() with the now unified
version accepted by {bus/class}_find_device(), where it doesn't
accept a "const" qualifier for the data argument. This prevents
us from reusing the generic match functions for driver_find_device().
For this reason, change the prototype of the driver_find_device() to
make the "match" parameter in line with {bus/class}_find_device()
and adjust its callers to use the const qualifier. Also, we could
now promote the "data" parameter to const as we pass it down
as a const parameter to the match functions.

There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device(). If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward. Also with that, constify
the "data" parameter as it is passed as a const to the match function.
For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

There is no point to print deferred probe (and its failures to get

unneeded error messages:
lima 13000000.gpu: failed to get regulator: -517
lima 13000000.gpu: regulator init fail -517
lima 13000000.gpu: Fatal error during GPU init
Also do not print clock rates before the initialization finishes
because they will be duplicated after deferral. Each probe step already
prints error so remove the final error message "Fatal error during GPU
init".
In case of multiple probe tries this would pollute the dmesg.

[Why]
To prepare for the upcoming DRM plane color management properties
we need to correct a lot of wrong behavior and assumptions made for
CRTC color management.
The documentation added by this commit in amdgpu_dm_color explains
how the HW color pipeline works and its limitations with the DRM
interface.
The current implementation does the following wrong:
- Implicit sRGB DGM when no CRTC DGM is set
- Implicit sRGB RGM when no CRTC RGM is set
- No way to specify a non-linear DGM matrix that produces correct output
- No way to specify a correct RGM when a linear DGM is used
We had workarounds for passing kms_color tests but not all of the
behavior we had wrong was covered by these tests (especially when
it comes to non-linear DGM). Testing both DGM and RGM at the same time
isn't something kms_color tests well either.
[How]
The specifics for how color management works in AMDGPU and the new
behavior can be found by reading the documentation added to
amdgpu_dm_color.c from this patch.
All of the incorrect cases from the old implementation have been
addressed for the atomic interface, but there still a few TODOs for
the legacy one.
Note: this does cause regressions for kms_color@pipe-a-ctm-* over HDMI.
The result looks correct from visual inspection but the CRC no longer
matches. For reference, the test was previously doing the following:
linear degamma -> CTM -> sRGB regamma -> RGB to YUV (709) -> ...
Now the test is doing:
linear degamma -> CTM -> linear regamma -> RGB to YUV (709) -> ...

Current policy assumes virtual DPCD peer device as

However this is only true for virtual DP-to-DP peer device.
In general there are three types of virtual DP peer devices.
1. Sink peer device with virtual DPCD.
2. Virtual DP-to-DP Peer device with virtual DPCD.
3. Virtual DP-to-HDMI Protocol Converter Peer Device with
Virtual DPCD.
So we should break the assumption and handle all three types.
[how]
DP-to-DP peer device will have virtual DPCD cap upstream.
Sink peer device will have virtual DPCD on the logical port.

[Why]
Almost every function in DC that works with stream state expects that
the current state on the stream is the one that it should be writing
out. These functions are typically triggered by specifying a particular
stream update - but the actual contents of the stream update itself
are ignored, leaving it to the DM to actually update the stream state
itself.
The problem with doing this in DM is a matter of timing. On Linux
most of this is incorrectly done in atomic check, when we actually want
it to be done during atomic commit tail while access to DC is locked.
To give an example, a commit requesting to modify color management
state for DM could come in, be rejected, but still have modified
the actual system state for the stream since it's shared memory. The
next time color management gets programmed it'll use the rejected
color management info - which might not even still be around if it's
a custom transfer function.
So a reasonable place to perform this is within DC itself and this is
the model that's currently in use for surface updates. DC can even
compare the current system state to the incoming surface update to
determine update level, something that can't currnetly be done with the
framework for stream updates.
[How]
Duplicate the framework used for surface updates for stream updates
as well. Copy all the updates after checking the update type.

[Why]
The output_bpp pipe parameter was assigned an incorrect value
(color depth enum), and subsequently used to overwrite
the OutputBpp parameter calculated by DML. Seems like this had no
effect except with DSC enabled, which would make DML produce
bad outputs.
[How]
Removed assignment to OutputBpp, fixed output_bpp assignment,
and properly set ForcedOutputLinkBPP instead of OutputBpp.
Also removed condition in DML that prevented forcing of
Output BPP with DSC enabled.

[why]
dsc adjustment is allowed via stream update sequence.
dsc enablement is only allowed via commit stream sequence.
with the current unified dsc set function, it is hard
to determine which sequence it is called by.
The solution is to decouple dsc adjustment out of enablement
sequence so we can handle them separately.
[how]
decouple dsc adjustment out of enablement.

[why]
current DML logic uses currently trained setting for number
of dp lanes in DML calculations. this is obviously flawed since
just because 1 lane is in use doesn't mean only 1 lane can be used
this causes mode validation to fail depending on current state,
which is incorrect
[how]
DML should always assume 4 lanes are available. validation of
bandwidth is not supposed to be handled by DML, since we do
link validation without DML already
also, DML is expecting there to be a copy of the max state, this
state is removed when update_bounding_box is called to update
actual SKU clocks. fix this as well by duping last state.

Plane disable gets calls when we enable blank. On DCN2, we blank by using
DPG to display a black colour instead of using OTG blank. DPG runs off the
OPP clock, therefore we shouldn't disable the OPP clock when disabling the

that will be addressed in a separate commit.
