The NOL and CAC timeout callback function is divided into two parts:
HardIRQ and workqueue. If NOL/CAC expires, the callback function runs in a
HardIRQ context and the rest of the task runs in a workqueue to avoid
deadlock issues.
Issue: Workqueue tasks run in a low-level context. The task's execution
might have been delayed.
To fix this, run the "NOL" and "CAC" timer in softirq context.
Use QDF_CONTEXT_TASKLET instead of QDF_CONTEXT_HARDWARE as a argument in
qdf_hrtimer_init. If it is a "QDF_CONTEXT_TASKLET," the HR timer
initialises with softIRQ mode(HRTIMER_MODE_SOFT) and runs in softRQ
context when timer expires.

When radar is found in any DFS channel, a radar bitmap is
generated based on the radar infected channels. For example,
if operating channel is 100 HT160 and radar found in 112,
then the generated bitmap is B0000_0010. This proposed bitmap
is compared with the valid puncturing patterns. In this case,
the proposed bitmap is valid puncturing pattern.
In case of a valid puncturing pattern, send the final
bitmap to DFS module and the module updates the DFS channel
puncturing pattern. If an invalid puncturing pattern is
found, return value zero and do not update DFS channel
puncturing pattern.

When radar is found on any DFS channel, generate a
bitmap which represents the channels that are
radar infected. For example, if the current channel
is 100 HT160 and radar is found in chan 104, then the
bitmap generated have the value B0000_0010. The bit 1
represents radar infected channels.
The radar bitmap calculation also checks for any existing
punctured patterns. If already punctured patterns are
available then it includes the existing pattern and
also current pattern in the bitmap calculation.

If radar is injected on the non-dfs segment of a DFS channel

-20, radarfound_freq = center freq + freq = 5230 (IEEE 46) which is a

To ensure that radar found event is indicated only for DFS channel,

radar into the HT20 primary channel. The primary channel is not being added
to NOL when marksubchannel is enabled because the current subchannel

(while using HR timers), no other timer cancellation is allowed

On CAC expiry, when VDEV UP is sent to FW, serialization timer is

It currently holds the value of primary 20MHz channel. With the

For the Chipsets that support this service, the radar found frequency
can be calculated by mere addition of the fields "chan_freq" and

2. Adding 320MHz bandwidth in switch case and separating
'case CH_WIDTH_320MHZ' using a compile time macro ( 11BE), forces us
to use the macro inside the function, which is not allowed by the
coding guideline.
Convert the "switch case" mapping (which is generally a binary search)
into a linear search of a mapping (BW -> bonded pair) array , thereby
using the macro WLAN_FEATURE_11BE to separate the 320MHz bandwidth
in the data structure space instead of doing the separation inside
