The commit 1f9d3d98694b1 ("ALSA: hda - set intel audio clock to a
proper value") added a number of misleading comments.
There is no ability to detect if an SCF value was set or not, what the
code does is prevent the use of the 6MHz audio clock represented by
the value 0 in LCTL.SCF. Changing the SCF settings does require the
link to be power-cycled, but in all other cases the link is powered
automatically when exiting reset. In other words, the power-cycle is
an exception to the rule that the HDaudio legacy driver does not need
to program SPA/CPA bits.
In addition, the SCF related changes are only relevant for the first
link.
No functionality change, only comment clarifications.

The conversion looks harmless, however the addr value is updated inside
the loop with the previous vm_end, which then incorrectly leads to
for_each_vma_range() iterating over stuff outside the range we care
about. Fix this by storing the end value separately. Also fix the case
where the range doesn't intersect with any vma, or if the vma itself
doesn't extend the entire range, which must mean we have hole at the
end. Both should result in an error, as per the previous behaviour.
v2: Fix the cases where the range is empty, or if there's a hole at
the end of the range

Currently we are observing mouse cursor stuttering when using
xrandr --scaling=1.2x1.2. X scaling/transformation seems to be
doing fronbuffer rendering. When moving mouse cursor X seems to
perform several invalidates and only one DirtyFB. I.e. it seems
to be assuming updates are sent to panel while drawing is done.
Earlier we were disabling PSR in frontbuffer invalidate call back
(when drawing in X started). PSR was re-enabled in frontbuffer
flush callback (dirtyfb ioctl). This was working fine with X
scaling/transformation. Now we are just enabling continuous full
frame (cff) in PSR invalidate callback. Enabling cff doesn't
trigger any updates. It just configures PSR to send full frame
when updates are sent. I.e. there are no updates on screen before
PSR flush callback is made. X seems to be doing several updates
in frontbuffer before doing dirtyfb ioctl.
Fix this by sending single update on every invalidate callback.

We need to iterate over the original entries here for the sg_table,
pulling out the struct page for each one, to be remapped. However
currently this incorrectly iterates over the final dma mapped entries,
which is likely just one gigantic sg entry if the iommu is enabled,
leading to us only mapping the first struct page (and any physically
contiguous pages following it), even if there is potentially lots more
data to follow.

When the R-Car MIPI DSI driver was added, it was a standalone encoder
driver without any dependency to or from the R-Car DU driver. Commit
957fe62d7d15 ("drm: rcar-du: Fix DSI enable & disable sequence") then
added a direct call from the DU driver to the MIPI DSI driver, without
updating Kconfig to take the new dependency into account. Fix it the
same way that the LVDS encoder is handled.

[ 420.333904] failed to register platform driver vc4_hvs_driver [vc4]: -16
modprobe: ERROR: could not insert 'vc4': Device or resource busy
The reason is that vc4_drm_register() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
fails, it returns without unregistering all the vc4 drivers, resulting the
vc4 can never be installed later.
A simple call graph is shown as below:
vc4_drm_register()
platform_register_drivers() # all vc4 drivers are registered
platform_driver_register()
driver_register()
bus_add_driver()
priv = kzalloc(...) # OOM happened
# return without unregister drivers
Fixing this problem by checking the return value of
platform_driver_register() and do platform_unregister_drivers() if
error happened.

Commit ae71ab585c81 ("drm/vc4: hdmi: Enforce the minimum rate at
runtime_resume") reintroduced the call to clk_set_min_rate in an attempt
to fix the boot without a monitor connected on the RaspberryPi3.
However, that introduced a regression breaking the display output
entirely (black screen but no vblank timeout) on the Pi4.
This is due to the fact that we now have in a typical modeset at boot,
in vc4_hdmi_encoder_pre_crtc_configure(), we have a first call to
clk_set_min_rate() asking for the minimum rate of the HSM clock for our
given resolution, and then a call to pm_runtime_resume_and_get(). We
will thus execute vc4_hdmi_runtime_resume() which, since the commit
mentioned above, will call clk_set_min_rate() a second time with the
absolute minimum rate we want to enforce on the HSM clock.
We're thus effectively erasing the minimum mandated by the mode we're
trying to set. The fact that only the Pi4 is affected is due to the fact
that it uses a different clock driver that tries to minimize the HSM
clock at all time. It will thus lower the HSM clock rate to 120MHz on
the second clk_set_min_rate() call.
The Pi3 doesn't use the same driver and will not change the frequency on
the second clk_set_min_rate() call since it's still within the new
boundaries and it doesn't have the code to minimize the clock rate as
needed. So even though the boundaries are still off, the clock rate is
still the right one for our given mode, so everything works.
There is a lot of moving parts, so I couldn't find any obvious
solution:
- Reverting the original is not an option, as that would break the Pi3
again.
- We can't move the clk_set_min_rate() call in _pre_crtc_configure()
since because, on the Pi3, the HSM clock has the CLK_SET_RATE_GATE
flag which prevents the clock rate from being changed after it's
been enabled. Our calls to clk_set_min_rate() can change it, so they
need to be done before clk_prepare_enable().
- We can't remove the call to clk_prepare_enable() from the
runtime_resume hook to put it into _pre_crtc_configure() either,
since we need that clock to be enabled to access the registers, and
we can't count on the fact that the display will be active in all
situations (doing any CEC operation, or listing the modes while
inactive are valid for example()).
- We can't drop the call to clk_set_min_rate() in
_pre_crtc_configure() since we would need to still enforce the
minimum rate for a given resolution, and runtime_resume doesn't have
access to the current mode, if there's any.
- We can't copy the TMDS character rate into vc4_hdmi and reuse it
since, because it's part of the KMS atomic state, it needs to be
protected by a mutex. Unfortunately, some functions (CEC operations,
mostly) can be reentrant (through the CEC framework) and still need
a pm_runtime_get.
However, we can work around this issue by leveraging the fact that the
clk_set_min_rate() calls set boundaries for its given struct clk, and
that each different clk_get() call will return a different instance of
struct clk. The clock framework will then aggregate the boundaries for
each struct clk instances linked to a given clock, plus its hardware
boundaries, and will use that.
We can thus get an extra HSM clock user for runtime_pm use only, and use
our different clock instances depending on the context: runtime_pm will
use its own to set the absolute minimum clock setup so that we never
lock the CPU waiting for a register access, and the modeset part will
set its requirement for the current resolution. And we let the CCF do
the coordination.
It's not an ideal solution, but it's fairly unintrusive and doesn't
really change any part of the logic so it looks like a rather safe fix.

and is now named vc4_hdmi_reset_link(). Let's fix the function name.

We access some fields protected by our internal mutex in
vc4_hdmi_reset_link() (saved_adjusted_mode, output_bpc, output_format)
and are calling functions that need to have that lock taken
(vc4_hdmi_supports_scrambling()).
However, the current code doesn't lock that mutex. Let's make sure it
does.

Currently, we are calling fill_dc_dirty_rects() even if PSR isn't
supported by the relevant link in amdgpu_dm_commit_planes(), this is
undesirable especially because when drm.debug is enabled we are printing
messages in fill_dc_dirty_rects() that are only useful for debugging PSR
(and confusing otherwise). So, we can instead limit the filling of dirty
rectangles to only when PSR is enabled.

[Why]
The link enablement sequence can end up resetting the encoder while
the PHY symclk isn't yet on.
This means that waiting for symclk on will timeout, along with the reset
bit never asserting high.
This causes unnecessary delay when enabling the link and produces a
warning affecting multiple IGT tests.
[How]
Don't wait for the symclk to be on here because firmware already does.
Don't wait for reset if we know the symclk isn't on.
Split the reset into a helper function that checks the bit and decides
whether or not a delay is sufficient.

[Why]
Recent backports from open source do not have header inclusion pattern
that is consistent with inclusion style in the rest of the file. This
breaks the internal tool builds as well. A recent commit erronously
modified the original DML formula for calculating
ActiveClockChangeLatencyHidingY. This resulted in a FCLK deviation
from the golden values.
[How]
Change the way in which display_mode_vba.h is included so that it is
consistent with the inclusion style in rest of the file which also fixes
the tool build. Restore the DML formula to its original state to fix the
FCLK deviation.

criu_checkpoint_bos has its own error handling and cleanup that does not
depend on access to user memory.
In the private data, keep BOs before the remaining objects. This is
necessary to restore things in the correct order as restoring events
depends on the events-page BO being restored first.

DMA sync functions should use the same direction that was used by DMA
mapping. Use DMA_BIDIRECTIONAL for XDP_TX from regular RQ, which reuses
the same mapping that was used for RX, and DMA_TO_DEVICE for XDP_TX from
XSK RQ and XDP_REDIRECT, which establish a new mapping in this
direction. On the RX side, use the same direction that was used when
setting up the mapping (DMA_BIDIRECTIONAL for XDP, DMA_FROM_DEVICE
otherwise).
Also don't skip sync for device when establishing a DMA_FROM_DEVICE
mapping for RX, as some architectures (ARM) may require invalidating
caches before the device can use the mapping. It doesn't break the
bugfix made in
commit 0b7cfa4082fb ("net/mlx5e: Fix page DMA map/unmap attributes"),
since the bug happened on unmap.

For a single CPU system, the kernel thread executing mlx5_cmd_flush()
never releases the CPU but calls down_trylock(&cmd→sem) in a busy loop.
On a single processor system, this leads to a deadlock as the kernel
thread which executes mlx5_cmd_invoke() never gets scheduled. Fix this,
by adding the cond_resched() call to the loop, allow the command
completion kernel thread to execute.

Mlx5 LAG is initialized asynchronously on a workqueue which means that for
a brief moment after setting mlx5 UL representors as lower devices of a
bond netdevice the LAG itself is not fully initialized in the driver. When
adding such bond device to a bridge mlx5 bridge code will not consider it
as offload-capable, skip creating necessary bookkeeping and fail any
further bridge offload-related commands with it (setting VLANs, offloading
FDBs, etc.). In order to make the error explicit during bridge
initialization stage implement the code that detects such condition during
NETDEV_PRECHANGEUPPER event and returns an error.
