cfg80211_ch_switch_notify uses ASSERT_WDEV_LOCK to assert that net_device->ieee80211_ptr->mtx (which is the same as priv->wdev.mtx) is held during the function's execution. mwifiex_dfs_chan_sw_work_queue is one of its callers, which does not hold that lock, therefore violating the assertion. Add a lock around the call. Disclaimer: I am currently working on a static analyser to detect missing locks. This was a reported case. I manually verified the report by looking at the code, so that I do not send wrong information or patches. After concluding that this seems to be a true positive, I created this patch. However, as I do not in fact have this particular hardware, I was unable to test it. Reviewed-by:

Add a dummy function for packet offload to eliminate warning message "c2h class 1 func 2 not support". This c2h is for debug purpose and its presence itself can do the work, so further parsing won't be required for now. Signed-off-by:

The PCI code of 8852AE and 8852CE are different, but the flow and register names are similar. To reuse the code, add a struct to define register or value accordingly. We also use chip id to control the slightly different flow. Signed-off-by:

No need to have goto for a return statement, so simplify the code. While at it, print warning messages if power up calls fail. No functional changes. Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2 Signed-off-by:

While reviewing the mhi.c I noticed we were just ignoring the errors coming from MHI subsystem during suspend and resume. Add proper checks and warning messages. Also pass the error value to callers. Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2 Signed-off-by:

State machines are difficult to understand and in this case it's just useless, which is shown by the diffstat. So remove it entirely to make the code simpler. No functional changes. Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2 Signed-off-by:

The smatch reports: rtw8852a.c:1857 rtw8852a_btc_set_wl_txpwr_ctrl() error: uninitialized symbol '_cur'. rtw8852a.c:1858 rtw8852a_btc_set_wl_txpwr_ctrl() error: uninitialized symbol '_cur'. This is because rtw89_mac_txpwr_read32() can possibly return before setting argument _cur, and the caller will use the uninitialized value. To fix this problem, check the return value of rtw89_mac_txpwr_read32(). Signed-off-by:

8852C uses different fields to represent RX bandwidth. Since other fields are the same, I check chip_id to get bandwidth instead of creating another v1 function. Signed-off-by:

The newer chip will generate security header itself, so don't set IEEE80211_KEY_FLAG_GENERATE_IV in this kind of chip. But, it needs to fill key_index, PN and 802.11 header length to TX descriptor, and then hardware uses these to generate security header. Signed-off-by:

The txdesc is descriptor related to skb->data. The v1 version contains 8 dwords txwd_body and 6 dwords txwd_info, and the format is also different from original one. Signed-off-by:

The txaddr_info is used to fill the DMA address of skb->data. The v1 version can support up to 10 entries, but the maximum size of each entry is 2047, so it fill more than one entry for large packet, like 3000 bytes. Signed-off-by:

Originally, there is already a mechanism, SER (system error recover), to deal with HW/FW recovery. After FW v0.13.36.0, FW supports a H2C (host to chip) command to make a CPU exception. Then, SER is supposed to catch this FW crash and do L2 reset. This feature is a simulation to verify if flow of recovering from FW crash works. Usage of fw_crash debugfs is as the following. $ echo 1 > fw_crash // trigger FW crash and wait SER handling $ cat fw_crash // return 0 if restart has been done Signed-off-by:

As the fw features gradually increase, it would be better that we have a set of methods to maintain fw features instead of using scattered bool variables. We reconstruct the way fw recognize features, and introduce RTW89_CHK_FW_FEATURE() / RTW89_SET_FW_FEATURE() to check / set fw features for uses. Signed-off-by:
