2020-08-31ath10k: wmi: Use struct_size() helper in ath10k_wmi_alloc_skb()Gustavo A. R. Silva1-24/+12
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. Also, remove unnecessary variable _len_. This code was detected with the help of Coccinelle and, audited and fixed manually. Signed-off-by: Gustavo A. R.

2020-08-27wcn36xx: Disable bmps when encryption is disabledLoic Poulain3-1/+15
For whatever reason, when connected to an open/no-security BSS, the wcn36xx controller in bmps mode does not forward 'wake-up' beacons despite AP sends DTIM with station AID. Meaning that AP is not able to wakeup the station and needs to wait for the station to wakeup by its own (TX data, keep alive pkt...), causing serious latency issues and unexpected deauth. When connected to AP with encryption enabled, this issue does not occur. So a simple workaround is to only enable bmps support in that case. Ideally, it should be propertly fixed to allow bmps support with open BSS, whatever the issue is at driver or firmware level. Tested on wcn3620 and wcn3680.

2020-08-27wcn36xx: Setup starting bitrate to MCS-5Loic Poulain2-0/+9
By default, after associated to an AP, the wcn36xx bitrate adjustment algorithm starts sending data at 1Mbps, and increases the rate slowly (1Mbps, 2Mbps, 6Mbps...) over the further TX packets. Starting at 1Mbps usually causes the initial throughput to be really low and the maximum possible bitrate to be reached after about hundreed of TX packets. That can be improved by setting a different initial bitrate for data packets via the ENABLE_DYNAMIC_RA_START_RATE configuration value, this value can be a legacy or MCS rate. This patch sets the starting bitrate value to MCS-5, which seems to be a good compromise given it can be quickly adjusted low or up if necessary.

For software-driven scan, rely on mac80211 software scan instead of internal driver implementation. The internal implementation cause connection trouble since it keep the antenna busy during the entire scan duration, moreover it's only a passive scanning (no probe request). Therefore, let mac80211 manages sw scan. Note: we fallback to software scan if firmware does not report scan offload support or if we need to scan the 5Ghz band (currently not supported by the offload scan...).

And RTS_CTS extended tid configuration support advertised through the service flag WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT. TID specific noack configuration requires aggregation should be disabled and rate for the data TID packets should be basic rates. So, if the TID already configured with noack policy then driver will ignore the aggregation or TX rate related configuration for the same data TID.

2020-08-19ath10k: sdio: add firmware coredump supportWen Gong5-4/+679
When firmware crashes it's possible to create a coredump for later analysis, add support to collect the register and memory info from SDIO devices. The coredump configuration is different between QCA6174 PCI and QCA6174 SDIO, so add specific registers and memory regions for the latter. QCA6174 SDIO has two methods to dump the firmware: fastdump and slowdump. Fastdump is not supported in olded versions of firmware, and for these ath10k will automatically select slowdump. If firmware supports fastdump, ath10k will automatically select it. QCA6174 SDIO firmware version WLAN.RMH.4.4.1-00017-QCARMSWPZ-2 is the first version supporting fastdump. For slowdump, ath10k_sdio_hif_diag_read() can not be used as the diag window has a limit value, it is 4 bytes and the dump's buffer length is larger than it, it will trigger error. So this patch adds ath10k_sdio_read_mem() to read 4 bytes for each time.

As a part of device shutdown the smmu driver will be stopped and henceforth any IOVA address translation will not be done. The wlan driver, being one of the smmu driver consumer, should stop all the dma related activity as a part of shutdown, and thereby ensuring that no dma activity is done once the smmu driver shuts down. During the device shutdown, the smmu calls shutdown for all its consumers in order to indicate them to stop all their dma activities. Register the shutdown handler to stop the wlan driver and avoid any dma operations.
