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.

Host needs to send station's MAC address along with TID number and its configuration to target through WMI_10_4_PER_PEER_PER_TID_CONFIG_CMDID. WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT flag is added to advertise this support.

Station specific TID configuration will have more priority than vif specific TID configuration. WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT service flag introduced to notify host for TID config support. 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. In TX rate configuration should be applied with highest preamble configuration(HT rates should not be applied for the station which supports vht rates).

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...).

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.

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.

Right now the code generates a summary register by iterating over all copy engines and seeing if they have an interrupt pending. This has a problem. Specifically if _none_ if the Copy Engines have an interrupt pending then they might go into low power mode and reading from their address space will cause a full system crash. This was seen to happen when two interrupts went off at nearly the same time. Both were handled by a single call of ath10k_snoc_napi_poll() but, because there were two interrupts handled and thus two calls to napi_schedule() there was still a second call to ath10k_snoc_napi_poll() which ran with no interrupts pending. Instead of iterating over all the copy engines, let's just keep track of the IRQs that fire. Then we can effectively generate our own summary without ever needing to read the Copy Engines.

Sat, 29 Aug 2020 04:38:41 +0100 Subject: [PATCH 41/59] wcn36xx: Fix warning due to bad rate_idx The rate_idx is the index of the bitrate in the supported rate table. However the 5Ghz band has a smaller legacy bitrate table than 2.4Ghz since it does not have the DSSS bitrates (1, 2, 5.5, 11). So in 5Ghz band the index should adjusted accrodingly (-4).
