Users of the Lenovo ThinkPad X13s have reported that Wi-Fi sometimes
breaks and the log fills up with errors like:
ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1484, expected 1492
ath11k_pci 0006:01:00.0: HTC Rx: insufficient length, got 1460, expected 1484
which based on a quick look at the driver seemed to indicate some kind
of ring-buffer corruption.
Miaoqing Pan tracked it down to the host seeing the updated destination
ring head pointer before the updated descriptor, and the error handling
for that in turn leaves the ring buffer in an inconsistent state.
Add the missing memory barrier to make sure that the descriptor is read
after the head pointer to address the root cause of the corruption while
fixing up the error handling in case there are ever any (ordering) bugs
on the device side.
Note that the READ_ONCE() are only needed to avoid compiler mischief in
case the ring-buffer helpers are ever inlined.

Firmware requests 2 segments at first. The first segment is of 6799360
whose allocation fails due to dma remapping not available. The success
is returned to firmware. Then firmware asks for 22 smaller segments
instead of 2 big ones. Those get allocated successfully. At suspend/
hibernation time, these segments aren't freed as they will be reused
by firmware after resuming.
After resuming, the firmware asks for the 2 segments again with the
first segment of 6799360 size. Since chunk->vaddr is not NULL, the
type and size are compared with the previous type and size to know if
it can be reused or not. Unfortunately, it is detected that it cannot
be reused and this first smaller segment is freed. Then we continue to
allocate 6799360 size memory which fails and ath11k_qmi_free_target_mem_chunk()
is called which frees the second smaller segment as well. Later success
is returned to firmware which asks for 22 smaller segments again. But
as we had freed 2 segments already, we'll allocate the first 2 new
smaller segments again and reuse the remaining 20. Hence 20 small
segments are being reused instead of 22.
Add skip logic when vaddr is set, but size/type don't match. Use the
same skip and success logic as used when dma_alloc_coherent() fails.
By skipping, the possibility of resume failure due to kernel failing to
allocate memory for QMI can be avoided.
kernel: ath11k_pci 0000:03:00.0: failed to allocate dma memory for qmi (524288 B type 1)
ath11k_pci 0000:03:00.0: failed to allocate qmi target memory: -22

The eviction fence destroy path incorrectly calls dma_fence_put() on
evf_mgr->ev_fence after releasing the ev_fence_lock. This introduces a
potential use-after-unlock or race because another thread concurrently
modifies evf_mgr->ev_fence.
Fix this by grabbing a local reference to evf_mgr->ev_fence under the
lock and using that for dma_fence_put() after waiting.

Switching from devm_ioremap to the platform variant ends up calling
devm_request_mem_region, which reserves the memory region for the

and other devices on the ahb.

According to the code documentation in ath12k_mac_op_hw_scan(), "if no
links of an ML VIF are already active on the radio corresponding to the
given scan frequency, the scan link (link ID 15) should be used". This rule
should apply to non-ML interfaces as well to maintain uniformity across the
driver. However, currently, link 0 is selected as the scan link during
non-ML operations.
Update the code to use scan link ID 15 in all cases.

For scanning purposes, the driver can use link ID 15 (scan link). A future
change will make non-ML interfaces to select the scan link. In this
scenario, arvif->link_id will be used to retrieve the link configuration in
ath12k_mac_vdev_create(). However, link ID 15 is not recognized as a valid
link ID in the upper kernel, which will result in a failure to fetch
link_conf and subsequently cause the scan to fail.
To avoid this issue, ensure link_conf is fetched only when the link ID is
within the valid range. Since link_conf cannot be retrieved using the scan
link, use vif->addr as the Ethernet address for creating the scan vdev.
This address will serve as the source address (address 2) in the probe
request frames during scanning. Additionally, use the automatic Tx power
value for the vdev. As this is a scan vdev, these values do not affect the
scan functionality.
Note that vif->addr will only be taken when a valid link_conf can not be
fetched. Otherwise, link_conf's address will be taken as address 2.

Standalone "nologreplay" mount option has been marked deprecated since
commit 74ef00185eb8 ("btrfs: introduce "rescue=" mount option"), which
dates back to v5.9 (2020).
Furthermore there is no other filesystem with the same named mount
option, so this one is btrfs specific and we will not hit the same
problem when removing "norecovery" mount option.
So let's remove the standalone "nologreplay" mount option.

Add Rx timestamp function when the Rx timestamp value is read directly
from the Rx descriptor. In order to extend the Rx timestamp value to 64
bit in hot path, the PHC time is cached in the receive groups.
Add supported Rx timestamp modes.

Add functions to request Tx timestamp for the PTP packets, read the Tx
timestamp when the completion tag for that packet is being received,
extend the Tx timestamp value and set the supported timestamping modes.
Tx timestamp is requested for the PTP packets by setting a TSYN bit and
index value in the Tx context descriptor. The driver assumption is that
the Tx timestamp value is ready to be read when the completion tag is
received. Then the driver schedules delayed work and the Tx timestamp
value read is requested through virtchnl message. At the end, the Tx
timestamp value is extended to 64-bit and provided back to the skb.

Tx timestamp capabilities are negotiated for the uplink Vport.
Driver receives information about the number of available Tx timestamp
latches, the size of Tx timestamp value and the set of indexes used
for Tx timestamping.
Add function to get the Tx timestamp capabilities and parse the uplink
vport flag.

PTP clock configuration operations - set time, adjust time and adjust
frequency are required to control the clock and maintain synchronization
process.
Extend get PTP capabilities function to request for the clock adjustments
and add functions to enable these actions using dedicated virtchnl
messages.

When the access to read PTP clock is specified as mailbox, the driver
needs to send virtchnl message to perform PTP actions. Message is sent
using idpf_mbq_opc_send_msg_to_peer_drv mailbox opcode, with the parameters
received during PTP capabilities negotiation.
Add functions to recognize PTP messages, move them to dedicated secondary
mailbox, read the PTP clock time and cross timestamp using mailbox
messages.
