If virtual hardware is detected, there is no reason to run the full

The commit stream function does not include surfaces of unaffected
streams, which may lead to some blank screens during mode change in some
edge cases. This commit adds surfaces of unaffected streams followed by

0e986cea03 drm/amd/display: Copy DC context in the commit streams
DC adds an instance of DML (which contains VBA) to each context, and
multiple threads might write back to the global VBA resulting in data
overwriting. To keep the consistency with other parts of the DC code,
this commit changes dc_commit_streams to copy the current DC state, and
as a result, it also changes the function signature to expect streams
instead of a context.

7b36f4d18e drm/amd/display: Enable new commit sequence only for DCN32x
Change commit sequence will impact all ASICs. It is prudent to run this
update in small steps to keep issues under control and avoid any
potential regression. With this idea in mind, this commit is preparation
work for the complete transition to the new commit sequence. To maintain
this change manageable across multiple ASICs, this commit adds a new
function named dc_commit_streams which is a copy of the dc_commit_state
with some minor changes. Finally, inside the dc_commit_state, we check
if we are using DCN32x or above and enable the new sequence only for
those devices.

720ca52bce net-memcg: avoid stalls when under memory pressure
As Shakeel explains the commit under Fixes had the unintended
side-effect of no longer pre-loading the cached memory allowance.
Even tho we previously dropped the first packet received when
over memory limit - the consecutive ones would get thru by using
the cache. The charging was happening in batches of 128kB, so
we'd let in 128kB (truesize) worth of packets per one drop.

After the change we no longer force charge, there will be no
cache filling side effects. This causes significant drops and
connection stalls for workloads which use a lot of page cache,
since we can't reclaim page cache under GFP_NOWAIT.

Some of the latency can be recovered by improving SACK reneg
handling but nowhere near enough to get back to the pre-5.15
performance (the application I'm experimenting with still
sees 5-10x worst latency).

Apply the suggested workaround of using GFP_ATOMIC. We will now
be more permissive than previously as we'll drop _no_ packets
in softirq when under pressure. But I can't think of any good
and simple way to address that within networking.

3d2af9cce3 tcp: fix indefinite deferral of RTO with SACK reneging
This commit fixes a bug that can cause a TCP data sender to repeatedly
defer RTOs when encountering SACK reneging.

The bug is that when we're in fast recovery in a scenario with SACK
reneging, every time we get an ACK we call tcp_check_sack_reneging()
and it can note the apparent SACK reneging and rearm the RTO timer for
srtt/2 into the future. In some SACK reneging scenarios that can
happen repeatedly until the receive window fills up, at which point
the sender can't send any more, the ACKs stop arriving, and the RTO
fires at srtt/2 after the last ACK. But that can take far too long
(O(10 secs)), since the connection is stuck in fast recovery with a
low cwnd that cannot grow beyond ssthresh, even if more bandwidth is
available.

This fix changes the logic in tcp_check_sack_reneging() to only rearm
the RTO timer if data is cumulatively ACKed, indicating forward
progress. This avoids this kind of nearly infinite loop of RTO timer
re-arming. In addition, this meets the goals of
tcp_check_sack_reneging() in handling Windows TCP behavior that looks
temporarily like SACK reneging but is not really.

Many thanks to Jakub Kicinski and Neil Spring, who reported this issue
and provided critical packet traces that enabled root-causing this
issue. Also, many thanks to Jakub Kicinski for testing this fix.

fec94f8c99 media: cedrus: h264: Optimize mv col buffer allocation
Currently allocation for mv col buffer pool is very wasteful. It
allocates memory for worst case which is a lot more than it's needed for
typical use. Fix that by replacing pool with individual allocations when
such buffer is really needed. At that time all needed information for
determining optimal mv col buffer size is also known.

0ee952c2f4 media: cedrus: h265: Associate mv col buffers with buffer
Currently mv col aux buffers are allocated as a pool. This is not
optimal because pool size equals number of buffers before stream is
started. Buffers can easily be allocated afterwards. In such cases,
invalid pointer is assigned to the decoding frame and Cedrus might
overwrite memory location which is allocated to different task.

Solve this issue with allocating mv col buffer once capture buffer is
actually used.

23ddb85daf media: adv748x: afe: Select input port when initializing AFE
When moving the input selection to adv748x_reset() it was missed that
during probe the device is reset _before_ the initialization and parsing
of DT by the AFE subdevice. This can lead to the wrong input port (in
case it's not port 0) being selected until the device is reset for the
first time.

Fix this by restoring the call to adv748x_afe_s_input() in the AFE
initialization while also keeping it in the adv748x_reset().
