2022-06-21wifi: rtw89: disable invalid phy reports for all ICsPo-Hao Huang1-3/+1
Previously we only disable invalid reports for 52A, since we plan to support more ICs in the future, enable settings for those as well.

2022-06-21wifi: rtw89: pci: fix PCI doesn't reclaim TX BD properlyPing-Ke Shih1-3/+6
TX BD (TX ring index) and TX WD (WiFi descriptor buffer) are freed asynchronously. With burst packets, we free TX WD, but the corresponding TX BD couldn't be freed yet. Then, TX can possibly get stuck due to no more TX BD. To avoid this, ignore reclaiming TX BD only if TX WD is no free space, because at this moment TX BD must have some spaces. Otherwise, we reclaim TX BD to resolve TX stuck issue.

2022-06-21wifi: rtw89: fix long RX latency in low power modePing-Ke Shih1-1/+7
In low power mode, regular IO is power off, so we don't schedule napi to poll RX and TX completion. Therefore, calling ieee80211_rx_napi() with napi instance causes long RX latency. To fix this, use NULL as argument, and then it can use netif_receive_skb_list() to receive.

Some warning messages could bother users. With proper handling, these situations don't really affect usage, but we still need to keep monitor these messages.

2022-06-21wifi: rtw89: enable VO TX AMPDUKuan-Chung Chen2-7/+92
To improve VO throughput, we enable VO TX AMPDU. We measure the latency of enable or disable VO TX AMPDU. The experimental results show that the difference between the two is insignificant only 300µs, so the little impact can be ignored for user experience. Moreover, we found some APs will have a group key handshake timeout issue when the EAPOL's TID is already setup BA session. Therefore, when transmitting EAPOL, if EAPOL's TID BA session is already setup, we need to delete it.

The BSSID mask of H2C is used to match BSSID of receiving packets. Normally, we set six bits BSSID mask to exactly match BSSID of packets sent by target AP. After we support multiple BSSID, it could connect a nontransmitted BSSID, so we can only match first five bytes of BSSID. That means we could possibly receive other AP's packets if only the last byte of BSSID is different from target AP.

I made a copy additional related cleanups: 1) There is no need to check "buffer" for NULL. That's handled by copy_from_user(). 2) The "h2c_len" variable cannot be negative because it is unsigned and because sscanf() does not return negative error codes.

Since SAR is more expected to follow U-NII bands to plan subbands, division of 6GHz band is quite different from defined enum of subbands which is used by PHY in most cases. It's hard and painful if we want to keep using the same enum on SAR. So, we introduce another enum for SAR subbands and adjust SAR flow to use it. Besides, since 6GHz SAR subbands won't be divided with edge alignment, some cases will span two SAR subbands. For these cases, we describe them within an array of rtw89_sar_span and take the smaller one between SAR settings of the two subbands.

2022-05-17rtw89: pci: only mask out INT indicator register for disable interrupt v1Ping-Ke Shih1-3/+0
The design of INT indicator register (R_AX_PCIE_HIMR00_V1) is to reduce IO during frequent interrupts, because it can stop chip sending interrupt to host if we just set this indicator to 0, not all IMR(s). This indicator register looks like a root interrupt controller of wifi chip. However, we can't set all other IMR(s) to 0 during we are running on interrupt service routine, or the indicator register can't reflect the status of certain interrupt happened during this period, and then miss some interrupts especially SER interrupt events.
