2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg8-0/+32
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

2023-11-08wifi: rt2x00: restart beacon queue when hardware resetShiji Yang2-0/+14
When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in hardware interface. However, mac80211 will not automatically stop the queue. If we don't manually stop the beacon queue, the queue will be deadlocked and unable to start again.

2023-11-08wifi: rt2x00: disable RTS threshold for rt2800 by defaultShiji Yang1-2/+2
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().

2023-11-08wifi: rt2x00: introduce DMA busy check watchdog for rt2800Shiji Yang3-11/+73
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.

2023-10-23wifi: rt2x00: fix rt2800 watchdog functionShiji Yang1-6/+11
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.

2023-08-25Fix nomenclature for USB and PCI wireless devicesAlan Stern1-1/+1
A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.

2023-08-23wifi: rt2x00: limit MT7620 TX power based on eeprom calibrationShiji Yang1-17/+40
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.

2022-09-19wifi: rt2x00: Fix "Error - Attempt to send packet over invalid queue 2"Hans de Goede1-1/+4
Even though ieee80211_hw.queues is set to 2, the ralink rt2x00 driver is seeing tx skbs submitted to it with the queue-id set to 2 / set to IEEE80211_AC_BE on a rt2500 card when associating with an access-point. This causes rt2x00queue_get_tx_queue() to return NULL and the following error to be logged: "ieee80211 phy0: rt2x00mac_tx: Error - Attempt to send packet over invalid queue 2", after which association with the AP fails. This patch works around this by mapping QID_AC_BE and QID_AC_BK to QID_AC_VI when there are only 2 tx_queues.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb Pull USB / Thunderbolt updates from Greg KH: "Here is the "big" set of USB and Thunderbolt driver changes for 5.18-rc1. For the most part it's been a quiet development cycle for the USB core, but there are the usual "hot spots" of development activity. Included in here are: - Thunderbolt driver updates: - fixes for devices without displayport adapters - lane bonding support and improvements - other minor changes based on device testing - dwc3 gadget driver changes. It seems this driver will never be finished given that the IP core is showing up in zillions of new devices and each implementation decides to do something different with it... - uvc gadget driver updates as more devices start to use and rely on this hardware as well - usb_maxpacket() api changes to remove an unneeded and unused parameter. - usb-serial driver device id updates and small cleanups - typec cleanups and fixes based on device testing - device tree updates for usb properties - lots of other small fixes and driver updates.
