Should spectrum_cs_config() fail, some resources need to be released as already done in the remove function. While at it, remove a useless and erroneous comment. The probe is spectrum_cs_probe(), not spectrum_cs_attach(). Fixes: 15b99ac1 ("[PATCH] pcmcia: add return value to _config() functions") Signed-off-by:

The register-based H2C/C2H are used to exchange commands and events with firmware. The exchange data is limited, but it is relatively simple, because it can work before HCI initialization. To make these code clean, use struct to access them. This patch doesn't change logic at all. Signed-off-by:

The next generation chips use different RX descriptor format, so add a chip_ops to hook suitable handlers. Also, the length of RX descriptor is different, so add a variable to store the length according to chip and descriptor content dynamically. Then, the code can be more general. Signed-off-by:

The register ranges of upcoming chips are different from current, and even existing chips have different ranges, so support longer length to dump registers. Then, user space can decide the ranges according to chip. Since arbitrary length (e.g. 7) would be a little complicated, so simply make length a multiple of 16.

H2C of packet offload needs to wait FW ACK by C2H. But, it's possible that packet offload happens during SER (system error recovery), e.g. SER L2 which restarts HW. More, packet offload flow isn't deferrable. So, the H2C wait may get `ret == 1` (unreachable). However, the logic FW deals with packet offload is simple enough, just clone content. It means that as long as the H2C is issued successfully, the thing will succeed sooner or later. Therefore, after we add a debug log when receiving ACK to packet offload, it would be acceptable that during SER, packet offload don't really wait for ACK. And, if debugging, we can still check its debug logs. Besides, we can expect that if we see SER before receiving ACK to packet offload, those debug logs of the ACK have a time difference.

Some specific H2C (host to chip command) needs waiting until FW ACK by C2H (chip to host event). However, during SER (system error recovery), most interrupts are disabled, so we can't receive C2H immediately. It causes this kind of H2C TX waits will always time out during SER. To save time spent by SER, we don't do these redundant waits. And, to make a difference from -ETIMEDOUT in other cases, we make the function return 1 for SER case. When some H2C callers really catch `ret == 1` at runtime, they can determine whether it's reasonable or not, and consider how to resolve their flow if needed. Signed-off-by:

The total_sta_assoc and the tdls_peer are used for statistics accodring to stations' information. L2 (Level 2) SER (system error recovery) will call ieee80211_restart_hw() which re-invokes sta_state ops. And then, the total_sta_assoc and tdls_peer will be re-increased. In case wrong statistics results, we reset them in SER L2 handling. Signed-off-by:

RTL8723DS comes in two variant and each of them has their own SDIO ID: - 0xd723 can connect two antennas. The WiFi part is still 1x1 so the second antenna can be dedicated to Bluetooth - 0xd724 can only connect one antenna so it's shared between WiFi and Bluetooth Add a new entry for the single antenna RTL8723DS (0xd724) which can be found on the MangoPi MQ-Quad. Also rename the existing RTL8723DS entry (0xd723) so it's name reflects that it's the variant with support for two antennas. Reviewed-by:

rtw_sdio_rx_isr() is responsible for receiving data from the wifi chip and is called from the SDIO interrupt handler when the interrupt status register (HISR) has the RX_REQUEST bit set. After the first batch of data has been processed by the driver the wifi chip may have more data ready to be read, which is managed by a loop in rtw_sdio_rx_isr(). It turns out that there are cases where the RX buffer length (from the REG_SDIO_RX0_REQ_LEN register) does not match the data we receive. The following two cases were observed with a RTL8723DS card: - RX length is smaller than the total packet length including overhead and actual data bytes (whose length is part of the buffer we read from the wifi chip and is stored in rtw_rx_pkt_stat.pkt_len). This can result in errors like: skbuff: skb_over_panic: text:ffff8000011924ac len:3341 put:3341 (one case observed was: RX buffer length = 1536 bytes but rtw_rx_pkt_stat.pkt_len = 1546 bytes, this is not valid as it means we need to read beyond the end of the buffer) - RX length looks valid but rtw_rx_pkt_stat.pkt_len is zero Check if the RX_REQUEST is set in the HISR register for each iteration inside rtw_sdio_rx_isr(). This mimics what the RTL8723DS vendor driver does and makes the driver only read more data if the RX_REQUEST bit is set (which seems to be a way for the card's hardware or firmware to tell the host that data is ready to be processed). For RTW_WCPU_11AC chips this check is not needed. The RTL8822BS vendor driver for example states that this check is unnecessary (but still uses it) and the RTL8822CS drops this check entirely.

Due to the firmware behavior with HT fixed rate setting, HT fixed rate MCS with NSS > 1 are treated as NSS = 1 HT rates in the firmware and enables the HT fixed rate of NSS = 1. This leads to HT fixed rate is always configured for NSS = 1 even though the user sets NSS = 2 or > 1 HT fixed MCS in the set bitrate command. Currently HT fixed MCS is sent via WMI peer assoc command. Fix this issue, by sending the HT fixed rate MCS in WMI peer fixed param instead of sending in peer assoc command.

wifi: ath11k: Relocate the func ath11k_mac_bitrate_mask_num_ht_rates() and change hweight16 to hweight8 Relocate the function ath11k_mac_bitrate_mask_num_ht_rates() definition to call this function from other functions which helps to avoid the compilation error (function not defined). ht_mcs[] is 1 byte array and it is enough to use hweight8() instead of hweight16(). Hence, fixed the same. Tested on: Compile tested only. Signed-off-by:

When vdev start/stop happens, response from firmware is received with delay and hence there is a timeout before VDEV can be up/down. Also, with maximum peers connected and when vdev stop occurs, firmware will take time to clean up all the peers and vap queues. In such cases as well, vdev start/stop response is sent by firmware with delay. Increase the vdev setup timeout as recommended by firmware team.

TSSI is transmitter signal strength indication, which is a close-loop hardware circuit to feedback actual transmitting power as a reference for next transmission. When we setup channel to connect an AP, it does full calibration. When switching bands or channels, it needs to reset hardware status to prevent use wrong feedback of previous transmission. To do TX power compensation reflecting current temperature, it loads tables of compensation values into registers according to channel and band group. Signed-off-by:

This is a newer chip, similar to the RTL8710BU in that it uses the same PHY status structs. Features: 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps. It can allegedly have Bluetooth, but that's not implemented here. This chip can have many RFE (RF front end) types, of which types 1 and 5 are the only ones tested. Many of the other types need different initialisation tables. They can be added if someone wants them. The vendor driver v5.8.6.2_35538.20191028_COEX20190910-0d02 from https://github.com/BrightX/rtl8192fu was used as reference, with additional device IDs taken from https://github.com/kelebek333/rtl8192fu-dkms. The vendor driver also claims to support devices with ID 0bda:a725, but that is found in some bluetooth-only devices, so it's not supported here. Signed-off-by:
