wifi: rt2x00: disable RTS threshold for rt2800 by default rt2800 has a lot of registers to control the RTS enable/disable status for different rates. And the driver control them via rt2800_set_rts_threshold(). When RTS was disabled in user interface, this function won't be called at all. This means that the RTS is still 'on' for CCK and OFDM rates. So we'd better to disable them by default because it should be like this. The RTS for HT20 and HT40 is already default off so we don't need to touch them. If we toggle the RTS status, these register bits will be enable/disable again by rt2800_set_rts_threshold().

wifi: rt2x00: introduce DMA busy check watchdog for rt2800 When I tried to fix the watchdog of rt2800, I found that sometimes the watchdog can not reset the hung device. This is because the queue is not completely stuck, it just becomes very slow. The MTK vendor driver for the new chip MT7603/MT7612 has a DMA busy watchdog to detect device hangs by checking DMA busy status. This watchdog implementation is something similar to it. To reduce unnecessary reset, we can check the INT_SOURCE_CSR register together as I found that when the radio hung, the RX/TX coherent interrupt will always stuck at triggered state. The 'watchdog' module parameter has been extended to control all watchdogs(0=disabled, 1=hang watchdog, 2=DMA watchdog, 3=both). This new watchdog function is a slight schedule and it won't affect the transmission speed. So we can turn on it by default. Due to the INT_SOURCE_CSR register is invalid on rt2800 USB NICs, the DMA busy watchdog will be automatically disabled for them. Tested on MT7620 and RT5350.

wifi: rt2x00: fix rt2800 watchdog function The watchdog function is broken on rt2800 series SoCs. This patch fixes the incorrect watchdog logic to make it work again. 1. Update current wdt queue index if it's not equal to the previous index. Watchdog compares the current and previous queue index to judge if the queue hung. 2. Make sure hung_{rx,tx} 'true' status won't be override by the normal queue. Any queue hangs should trigger a reset action. 3. Clear the watchdog counter of all queues before resetting the hardware. This change may help to avoid the reset loop. 4. Change hang check function return type to bool as we only need to return two status, yes or no.

wifi: rt2x00: limit MT7620 TX power based on eeprom calibration In the vendor driver, the current channel power is queried from EEPROM_TXPOWER_BG1 and EEPROM_TXPOWER_BG2. And then the mixed value will be written into the low half-word of the TX_ALC_CFG_0 register. The high half-word of the TX_ALC_CFG_0 is a fixed value 0x2f2f. We can't get the accurate TX power. Based on my tests and the new MediaTek mt76 driver source code, the real TX power is approximately equal to channel_power + (max) rate_power. Usually max rate_power is the gain of the OFDM 6M rate, which can be readed from the offset EEPROM_TXPOWER_BYRATE +1. Based on these eeprom values, this patch adds basic TX power control for the MT7620 and limits its maximum TX power. This can avoid the link speed decrease caused by chip overheating. rt2800_config_alc() function has also been renamed to rt2800_config_alc_rt6352() because it's only used by RT6352 (MT7620). Notice: It's still need some work to sync the max channel power to the user interface. This part is missing from the rt2x00 driver framework. If we set the power exceed the calibration value, it won't take effect.

mac80211: prepare sta handling for MLO support Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Hence remove errornous line 5281 to make the driver actually execute the correct initialization routine for MT7620 chips. As it was requested by Stanislaw Gruszka remove setting values of MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO power-safe mode (which is disabled), hence we can drop setting it. TX_PIN_CFG is set correctly in other functions, and as setting this value breaks some devices, rather don't set it here during init, but only modify it later on.

mac80211: simplify TX aggregation start There really is no need to make drivers call the ieee80211_start_tx_ba_cb_irqsafe() function and then schedule the worker if all we want is to set a bit. Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.

As reported by Sergey: "I got some problem after upgrade kernel to 5.2 version (debian testing linux-image-5.2.0-2-amd64). 5Ghz client stopped to see AP. Some tests with 1metre distance between client-AP: 2.4Ghz -22dBm, for 5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not visible." It was identified that rx signal level degradation was caused by 9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band"). So revert this commit.

rt2x00: rt2800lib: add support for RT3352 with 20MHz crystal On Rt3352 the driver needs to know the frequency of an external crystal which can be either 40 MHz (as on all other WiSoCs until now) or 20 MHz. Get the clock attached by ramips WiSoC platform code which probes SYSC_REG_SYSCFG (added by John Crispin in commit 6ac8579b96e3b) and introduce a new flag clk_is_20mhz in struct hw_mode_spec to make the driver aware and use either 40 MHz or 20 MHz specific rf_vals on those WiSoC platforms. The introduced support for boards with a 20 MHz crystal is also needed for RT5350.

rt2800: tune TX_RTS_CFG config Enable RTS frame retry fall-back and limit number of RTS retries to 7 what is default number of retries for small frames. As RTS/CTS is used for TXOP protection, those settings prevent posting lots of RTS frames when remote station do not response with CTS at the moment. After sending 7 RTS's the HW will start back-off mechanism and after it will start posing RTS again to get access to the medium.

rt2800: change default retry settings We do not have option to set per frame retry count. We have only global TX_RTY_CFG registers which specify the number or retries. Set setting of that register to value that correspond rate control algorithm number of frame post (number of retries + 1), which is 3 for aggregated frames. This should help with big amount of retries on bad conditions, hence mitigate buffer-bloat like problems.

rt2800: set MAX_PSDU len according to remote STAs capabilities MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length (0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to remote stations capabilities (based on HT ampdu_factor). However limit the value based our hardware TX capabilities as some chips can not send more than 16kB (factor 1). Limit for all chips is currently 32kB (factor 2), but perhaps for some chips this could be increased to 64kB by setting drv_data->max_psdu to 3. Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes (AP, IBSS, mesh) we limit according to less capable remote STA. We can not set bigger value to speed up communication with some stations and do not break communication with slow stations.
