The generic scan command functions are now irrelevant, since both sched and regular scans are in the same code. So rename this functions to dwell and isolate all the dwell-related setting to them. Keeping the dwell code separate makes it easier to compare the LMAC and UMAC versions. Signed-off-by:

Having an LMAC counterpart for the existing UMAC flags function makes things more consistent and easy to compare and spot the differences. The flags are the same, but are in different bits, so unfortunately we can't use a single function for both APIs. Signed-off-by:

Clean the code a little by moving all the flags into the right function. Additionally, rename the function, since "common" is now irrelevant. Signed-off-by:

When we use an external buffer, it is allocated from the t DRAM and can be as big as 64MB. This buffer is huge and might not be needed for the specific issue being chased. Especially if lots of dumps are going to be created. Allow to limit the size of the buffer in the configuration. Signed-off-by: -

With just a few differences left in the UMAC scan functions now, we can merge them into one, taking care of the small difference according to the total number of iterations required. Signed-off-by:

In theory, LMAC scans can handle a 32-bit delay, but since waiting for over 18 hours to start the scan is a bit silly and to keep it aligned with UMAC scans (which only support 16-bit delays), trim it down to 16-bits. This makes the LMAC vs. UMAC and the UMAC reg scan vs. UMAC sched scan code more similar. Signed-off-by:

The last remaining difference between the regular scan and scheduled scan flows for LMAC is the FW capabilities check for EBS scans. Merge these checks into a new function and then combine the LMAC scan functions into a single one. Signed-off-by:

Luciano Coelho authored
As another step towards combining the scan and sched scan functions, add parameters that tell the scan function how many iterations we want (i.e. 1 for normal scan, more for scheduled scan) and that set the full scan multiplier (only meaningful for LMAC). Signed-off-by:

The probe request to be added to both LMAC and UMAC scan commands are identical, so move the generation out of the LMAC/UMAC-specific code. Signed-off-by:

Now that both scheduled scan and regular scan SSID populating functions do the same thing, they can be combined into a single function. Signed-off-by:
-
Luciano Coelho authored
The firmware inverts the order of the SSIDs sent out in probe requests (for some reason). For regular scans, we've been passing the SSIDs in the opposite order so they go out in the order we want. With scheduled scans, we were not doing that, so they were sent out in reverse order of priority. Fix that by using the reverse order when populating the SSIDs array for scheduled scans as well. Signed-off-by:

Luciano Coelho authored
The only difference in the ssid_bitmap between LMAC and UMAC scans is that in LMAC bits 1 to 20 are used, while in UMAC bits 0 to 19 are used (*sigh*). So we can combine the bitmap creation into a single function and simply shift left if LMAC is used. Signed-off-by:

Many parameters are common for all scans. Instead of parsing the cfg80211 scan and sched scan requests differently in each flow, move the parsing outside of the API/scan-type specific functions. In this way, we only need to differentiate between scan types once. Signed-off-by:

Similarly to the regular scan patch, a lot of the UMAC and LMAC sched scan code is also almost identical. Grab the low hanging fruits by combining the obvious parts. Signed-off-by:

Usually during HW recovery the state of all active interfaces is cleaned up during drv_start(). There's a special case where a HW restart is requested when an interface is going down. In this case the iface-iterator won't see this interface and we won't clean it. This has bad consequences once the interface is legitimately brought up again. Signed-off-by:

Instead of repeating the same code in 4 different places, combine the comparisons into a new function. Additionally, this change fixes UMAC scans where the RRM IEs were not taken into consideration when calculating the IE length. Signed-off-by:

Remove unused struct iwl_scan_offload_req and enum iwl_scan_offload_flags which are not used anymore. Rename iwl_scan_offload_schedule to iwl_scan_schedule_lmac to make it clear that this is for LMAC only. And fix a small typo. Signed-off-by:

Previously there was a check that compared window->average_tpt to some value, and if it was different - it set it to that value. However, this value was already calculated and set in _rs_collect_tx_data(), so the entire check is unneeded. Signed-off-by:

Net-detect scans were using the same type as sched scan, which was causing the driver to return -EBUSY and prevent the system from suspending if there was an ongoing scheduled scan. To avoid this, add a new type for net-detect and don't stop anything when it is requested, so that the existing scheduled scan will be resumed when the system wakes up. Signed-off-by:

All scans are using the unified APIs now, so using "unified" in the symbols is useless and just make them much longer and the main difference between scans now is LMAC vs. UMAC. Remove "unified" from all relevant symbols. Signed-off-by:

Instead of hardcoding the differences between UMAC scans and LMAC scans (which in this case is the number of simultaneous scans that can run), introduce a max_scans variable and stop scans of the other type (i.e. stop sched scan if regular scan is being attempted and vice-versa) if the number of running scans reached the maximum. Add a function that checks if the maximum number of scans was reached and stops the appropriate scan to make room for the new scan. Signed-off-by:

If a new scan cannot be run for some reason, we shouldn't cancel other ongoing scans. Move the checks to before the code that cancels other scans. Signed-off-by:

Now that we have separate flags for stopping scans, we don't need to wait for the scan stopped work to complete before starting the new scan. Previously we needed it because we had no way of distinguishing the scan that was being stopped from the scan that was currently running. With the new flags there won't be any confusions and we are able to handle the stop for the correct type of scan. Thus we can remove the iwl_mvm_cancel_scan_wait_notif() function. Signed-off-by:

LMAC scans cannot handle more than one scan at a time, but UMAC scans can. To avoid confusion we should combine the states of these two types of scans. To do so, we need to support mutliple scans at the same time for UMAC. This commit changes the scan_status element from a single value to a bitmask of running scan types for LMAC. Later, we will modify UMAC scans to use the same state bitmask. Additionally, add stopping scan flags for scheduled and regular scans. This makes it easier to differentiate and handle stop requests triggered by the driver and spontaneous stops generated by the firmware. Signed-off-by:

In some cases, max_out_time value is smaller than 200 and having the NL80211_SCAN_FLAG_LOW_PRIORITY flag was actually causing the max_out_time to be increased. To avoid that, set max_out_time to 200 only if it's greater than 200. Signed-off-by:

When user space requests mac80211 to transmit a frame off channel, mac80211 notifies the driver, and the driver requests a time event from the ucode, and then transmits the frame. When the driver requests a time event, it can specify what is the allowed max delay for starting the time event. When the max delay is too big, this can cause a timeout in the user space, that is waiting for the frame to be transmitted. Currently the max delay is extremely long. Reduce the max delay for the AUX ROC time event that is sent to the ucode. Signed-off-by:
