ba9e7a24f6 qcacmn: Avoid excessive logging
Issue: log level for some frequent prints is set to info
those logs would be present in dmesg as well as driver logs
and System performance may get affected due to excessive
logging.

Fix: Avoid redundant logs which may affect system
performance and change default log level to debug.

8461a8d5cd qcacmn: Do not skip CAC if Spoof test is not complete
In Dependent Repeater, if the Repeater STA is connected to a Root-AP
in a DFS channel, then the Repeater AP which is configured in ETSI
domain comes up in the DFS channel doing CAC.

In FCC domain, whenever Spoof radar pulse comes, we check if the Spoof
check is done and skip the CAC accordingly. In case of other domains,
Spoof events are not present. Therefore, Spoof test can be always
considered complete for non-FCC domains. Also the test can always be
considered complete if the target/FW does not support spoof test.

f878c39090 qcacmn: Make init of dfs->dfs_soc_obj independent of the macros
With the current implementation dfs->dfs_soc_object was initialized in
function dfs_agile_soc_obj_init under the macro QCA_SUPPORT_AGILE_DFS
and ATH_SUPPORT_ZERO_CAC_DFS both of which are disabled for the low
memory profiles. Hence the dfs->dfs_soc_obj was not initialized for these

dfs_is_true_160mhz_supported and dfs_is_restricted_80p80mhz_supported.

psoc = dfs->dfs_soc_obj->psoc

c70a7a8d0f qcacmn: Send VDEV_UP after spoof radar in Rep-AP
In Partial-Offload, when a repeater is associated with Root-AP in
DFS channel. The Repeater STA will get connected with Root-AP and then
Repeater-AP comes up in the DFS channel but it does not send beacons.

The reason is, when a STA vap is UP and in connected state, CAC is
skipped. So, for Repeater-AP we send VDEV_UP before Spoof radar
pulses event. FW rejects the VDEV_UP sent by host and therefore
Repeater-AP will be in UP state but it does not send any beacons.

The fix is, while checking the condition if STA vap is set to true, we
also check whether spoof radar event is completed. If the spoof radar
event is not completed, then we will not skip CAC and then VDEV UP
will be sent after the Spoof radar event.

adae9cdb21 qcacmn: Do not modify radar found params while processing it
The radar found parameters processing API dfs_process_radar_ind() is
supposed to read-only the radar_found_info parameters and not modify
them. A block of code for PO platforms modify the radar_found_info

The function dfs_process_radar_ind() should not modify the radar found

Since in this case the parameter modifications are specific to partial
offload, move the code that modifies the parameters out of the function
into a partial offload specific code.

NOTE:- The previous change I2c717219d0b0f9263734767bee6070f335032b04 also

e62226ba5f qcacmn: Do not update ch_params if RCAC frequency is NULL
While selecting the next channel after radar, if RCAC is enabled,
RCAC frequency and ch params are chosen. But in case where no
RCAC frequency was found, ch params were filled with 0s which are
then used by the next channel selection logic (random channel)
to figure out the next channel.

Since the ch params were now 0s, the ch width is pointing to
20MHz (0 enum) which results in a 20MHz channel picked irrespective
of current mode.

Do not modify ch params if the RCAC frequency is NULL.

4c6b5c6f69 qcacmn: DFS API support for Rolling CAC
An extension of preCAC feature is Rolling CAC. The distinct difference
between these features is that the FW runs the off channel CAC
timer for a "finite" time for preCAC and runs the timer for "infinite"
time on an off channel. Hence the infrastructure built for
preCAC feature is being modified to accommodate RCAC feature as well.
Following are the modifications done:

1. Add an enum to represent various off-channel CAC modes.
2. Remove the 'static' declaration of few APIS so as to re-use them.
3. Add 'dfs_rcac_ch_params' to DFS PDEV object to store the RCAC
channel params so as to use the channel params after radar detect.

4dab98d3ce qcacmn: Add DFS APIs for Rolling CAC feature
Feature Description:
FCC/JP domains do not support PreCAC. However, we can always start
beaconning in a channel if we have completed CAC in that channel for more
than or equal to the CAC period of that channel.
If an Agile engine is available and the next channel is known, we can
start CAC in the next channel using agile, while continuing the Tx/Rx
in the current channel. And when we want to start beaconning in the
next channel after a radar detection (or after/for a user request) we can
do so without any new CAC. This allows us to jump to the new channel
without having to disrupt any ongoing data traffic. This type of
continuous CAC in the next channel while operating in the current channel
is known as Rolling CAC.

Following changes are implemented:
I)Per DFS PDEV:
1) 'dfs_agile_rcac_freq' to store agile RCAC frequency.
2) 'dfs_agile_rcac_ucfg' to enable/disable RCAC feature.

II)Per DFS PSOC:
1) 'dfs_rcac_timer' is the only RCAC timer for the device/Psoc. This will
be shared by pdev level dfs objects.
2) 'dfs_rcac_timer_running' to indicate if RCAC is running or not.

III) New APIs:
1. A dispatcher API 'ucfg_dfs_set_rcac_enable' to set rcac config.
2. A dispatcher API 'ucfg_dfs_get_rcac_enable' to get rcac_config.
3. A dispatcher API 'ucfg_dfs_set_rcac_freq' to set user configured
rcac freq.
4. A dispatcher API 'ucfg_dfs_get_rcac_freq' to get the user configured
rcac freq.
5. Rolling CAC timer init/deinit APIs.

1d4f7736d3 qcacmn: Use frequency ranges for copying NOL after mode switch
Current NOL conversion for dynamic mode switch is in such a way
that the NOL data is copied to the pdev ID entry for the targeted
mode. That is, the NOL data is split/merged before mode switch and
copied to a temporary structure before mode switch command is
sent to FW.
At this point, the target pdev's frequency range are still the old
values because of which, certain entries of the NOL data are missed.
Also in case of FW failures, the NOL entry cannot be added back
because they have been merged/split already.

To avoid the above, rearchitecture deinit and reinit NOL for
mode switch in such a way that the NOL data, as-it-is, is copied
before mode switch and is only split/merged after the frequency range
of the pdevs are properly mapped and the FW response is a success.

86eba5902e qcacmn: Reinit DFS after HW mode switch (phase 2)
Supported dynamic HW mode switches:
DBS (full band 5G and 2G) <-> DBS_SBS (low band 5G, high band 5G and 2G)

Description of the changes:

1. NOL conversion:
  a. Introduce a temporary NOL list copy structure in DFS psoc obj.
  b. When mode switch is triggered:
    i.   Stop the NOL timers and clear the data, to avoid processing NOL
         expiry during mode switch.
    ii.  Allocate the psoc NOL copy for the target num_radios.
    iii. Store the NOL data of each radio to the target pdev ID
         (pdev ID after mode switch) in the psoc NOL copy,
	 using a unified mux/demux API.
  c. After mode switch is completed:
    i.   Resume NOL by re-initializing the list from the temporary psoc
         copy.
    ii.  Free the psoc copy after mode switch is complete.
    iii. Note: changes are made to support pause and resume of NOL,
         increasing NOL timeout by a few milliseconds.

2. PreCAC list conversion:
  a. When mode switch is triggered:
    i. Stop the existing preCAC timer and send ADFS abort command to FW.
  b. When mode switch is completed:
    i.  Unify/separate the preCAC list if the target mode is DBS/DBS_SBS
        respectively, using a single API.
    ii. Start ADFS again.

3. Radar detection lock:
  a. While detecting radar, acquire a lock to avoid handling user triggered
     mode_switch during this process. Release the lock once radar
     processing is completed and CSA start is triggered.

4. Radar detection/CAC completion defer during mode switch:
  a. While detecting radar or CAC completion, check if mode switch is
     in progress. If yes, defer the processing and wait for mode switch to
     complete before handling the events.
  b. Note: Precedence is Radar over CAC, i.e., if CAC processing is waiting
     and radar is received, CAC completion is no longer handled.

52ee85cf6f qcacmn: Add support to choose 160MHz random channel for Pine
Pine supports restricted 80+80 MHz only on cfreq=5690 and cfreq=5775. If AP
detects RADAR in this channel, it chooses new 80+80 MHz random channel
which is not supported by Pine because, notion of 80+80 is not present in
current channel in regulatory component. Hence, as a temporary fix we
change the invalid 80+80 MHz channel to 160 MHz or lower.

6810d038e9 qcacmn: Fix issues in random channel selection algorithm
Remove dummy function dfs_remove_cur_ch_from_list(). This logic is already
implemented in dfs_apply_rules().

In dfs_apply_rules()/dfs_apply_rules_for_freq(), skip all the HT20 channels
of the curent channel when DFS_RANDOM_CH_FLAG_NO_CURR_OPE_CH flag is set.

In dfs_prepare_random_channel_for_freq(), allocate correct size of memory
for leakage_adjusted_lst array.

Use DFS_80_NUM_SUB_CHANNEL macro instead of DFS_80_NUM_SUB_CHANNEL_FREQ to
choose correct 80MHz channel.

42bc1a9d68 qcacmn: Reset dfs_precac_active flag only for the calling pdev
When tgt_dfs_set_precac_state API is called, the dfs_precac_active
boolean is set to false for all pdevs. This results in preCAC
being stopped for all pdevs in DBS_SBS mode when one of the
pdev becomes inactive.

Reset dfs_precac_active flag only for the calling pdev and
set the global boolean 'precac_state_started' to false only
if all the individual pdev flags are inactive.

To avoid "channel number" collision with the introduction of

Also, do not remove the old IEEE channel-number-based APIs that are still
referenced.

The DFS APIs of Target-IF layer and DFS UTILS in DFS dispatcher layer are
included as a part of this change as they invoke DFS Core APIs and are
dependent.
