link_dp_training_dpia.c
wait_time_microsec = max(wait_time_microsec, (uint32_t)
DPIA_CLK_SYNC_DELAY);
Above line is trying to assign the maximum value between
'wait_time_microsec' and 'DPIA_CLK_SYNC_DELAY' to wait_time_microsec.
However, 'wait_time_microsec' has not been assigned a value before this
line, initialize 'wait_time_microsec' at the point of declaration.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_training_dpia.c:697 dpia_training_eq_non_transparent() error: uninitialized symbol 'wait_time_microsec'.

We have observed that there are quite a number of PSR-SU panels on the
market that are unable to keep up with what user space throws at them,
resulting in hangs and random black screens. So, make damage clips
support configurable and disable it by default for PSR-SU displays.

Pull firewire fix from Takashi Sakamoto:
"A change to accelerate the device detection step in some cases.
In the self-identification step after bus-reset, all nodes in the same
bus broadcast selfID packet including the value of gap count. The
value is related to the cable hops between nodes, and used to
calculate the subaction gap and the arbitration reset gap.
When each node has the different value of the gap count, the
asynchronous communication between them is unreliable, since an
asynchronous transaction could be interrupted by another asynchronous
transaction before completion. The gap count inconsistency can be
resolved by several ways; e.g. the transfer of PHY configuration
packet and generation of bus-reset.
The current implementation of firewire stack can correctly detect the
gap count inconsistency, however the recovery action from the
inconsistency tends to be delayed after reading configuration ROM of
root node. This results in the long time to probe devices in some
combinations of hardware.
Here the stack is changed to schedule the action as soon as possible"

Pull EFI fixes from Ard Biesheuvel:
"The only notable change here is the patch that changes the way we deal
with spurious errors from the EFI memory attribute protocol. This will
be backported to v6.6, and is intended to ensure that we will not
paint ourselves into a corner when we tighten this further in order to
comply with MS requirements on signed EFI code.
Note that this protocol does not currently exist in x86 production
systems in the field, only in Microsoft's fork of OVMF, but it will be
mandatory for Windows logo certification for x86 PCs in the future.
- Tighten ELF relocation checks on the RISC-V EFI stub
- Give up if the new EFI memory attributes protocol fails spuriously
on x86
- Take care not to place the kernel in the lowest 16 MB of DRAM on

Ensure no remaining requests in virtqueues before resetting vdev and
deleting virtqueues. Otherwise these requests will never be completed.
It may cause the system to become unresponsive.
Function blk_mq_quiesce_queue() can ensure that requests have become
in_flight status, but it cannot guarantee that requests have been
processed by the device. Virtqueues should never be deleted before
all requests become complete status.
Function blk_mq_freeze_queue() ensure that all requests in virtqueues
become complete status. And no requests can enter in virtqueues.

Symptom:
In case of a bad cable connection (e.g. dirty optics) a fast sequence of
network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth
interface. In case of a second DOWN while recovery is still ongoing, it
can happen that the IP@ of a Layer3 qeth interface is lost and will not
be recovered by the second UP.
Problem:
When registration of IP addresses with Layer 3 qeth devices fails, (e.g.
because of bad address format) the respective IP address is deleted from
its hash-table in the driver. If registration fails because of a ENETDOWN
condition, the address should stay in the hashtable, so a subsequent
recovery can restore it.
3caa4af834df ("qeth: keep ip-address after LAN_OFFLINE failure")
fixes this for registration failures during normal operation, but not
during recovery.
Solution:
Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For
consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE,
i.e. for some reason the card already/still has this address registered.

Since commit 48e1b4d369cf ("gpiolib: remove the GPIO device from the list
when it's unregistered") we remove the GPIO device entry from the global
list (used to order devices by their GPIO ranges) when unregistering the
chip, not when releasing the device. It will not happen when the last
reference is put anymore. This means, we need to remove it in error path
in gpiochip_add_data_with_key() unconditionally, without checking if the
device's .release() callback is set.

If GUP fails and we are in_kthread, we can have pinned = 0 and ret = 0.
If that happens we call sg_alloc_append_table_from_pages() with n_pages
= 0, which is not well behaved and can trigger:
kernel BUG at include/linux/scatterlist.h:115!
depending on if the pages array happens to be zeroed or not. Even if we

'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.
The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior
Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.
Thus fixing Buffer overflow error in dcn301_stream_encoder_create

Previously we would call apply_ctx_to_hw to enable and disable
phantom pipes. However, apply_ctx_to_hw can potentially update
non-phantom pipes as well which is undesired. Instead of calling
apply_ctx_to_hw as a whole, call the relevant helpers for each
phantom pipe when enabling / disabling which will avoid us modifying
hardware state for non-phantom pipes unknowingly.
The use case is for an FRL display where FRL_Update is requested
by the display. In this case link_state_valid flag is cleared in
a passive callback thread and should be handled in the next stream /
link update. However, due to the call to apply_ctx_to_hw for the
phantom pipes during a flip, the main pipes were modified outside
of the desired sequence (driver does not handle link_state_valid = 0
on flips).

With a second DP monitor connected, drm_atomic_state in dm atomic check
sequence does not include the connector state for the old/existing/first
DP monitor. In such case, dsc determination policy would hit a null ptr
when it tries to iterate the old/existing stream that does not have a
valid connector state attached to it. When that happens, dm atomic check
should call drm_atomic_get_connector_state for a new connector state.
Existing dm has already done that, except for RV due to it does not have
official support of dsc where .num_dsc is not defined in dcn10 resource
cap, that prevent from getting drm_atomic_get_connector_state called.
So, skip dsc determination policy for ASICs that don't have DSC support.

[Why]
To match firmware measurements and avoid hanging when accessing HW
that's in idle.
[How]
Increase the delays to what we've measured.
