2021-03-17module: remove never implemented MODULE_SUPPORTED_DEVICELeon Romanovsky
MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not.

2019-06-25rt2800: initial watchdog implementationStanislaw Gruszka
Add watchdog for rt2800 devices. For now it only detect hung and print error. [Note: I verified that printing messages from process context is fine on MT7620 (WT3020) platform that have problem when printk is called from interrupt context].

2019-06-25rt2800: add helpers for reading dma done indexStanislaw Gruszka
For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE interrupts, what is rather not worth to do due to adding extra CPU load (small but still somewhat not necessary otherwise). We can just read TX DMA done indexes from registers directly. What will be used by watchdog. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2017-03-08rt2x00: use txdone_nomatch on rt2800usbStanislaw Gruszka
If we do not match skb entry, provide tx status via nomatch procedure. Currently in that case we do rt2x00lib_txdone_noinfo(TXDONE_NOINFO), which actually assume that entry->skb was posted without retries and provide rate saved in skb desc as successful. Patch changed that to rate read from TX_STAT_FIFO, however still do not provide correct number of retries. On SoC/PCI devices we keep providing status via standard txdone procedure, no change in those devices, though we should thing about it.

2017-01-17rt2800: increase TX timeoutStanislaw Gruszka
When medium is busy or frames have to be resend, it takes time to send the frames and get TX status from hardware. For some really bad medium conditions it can take seconds. Patch change TX status timeout to give HW more time to provide it, however 500ms is not enough for bad conditions. In the future this timeout should be removed and replaced with proper watchdog mechanism. Increase flush timeout accordingly as well.

2017-01-17rt2800usb: remove watchdogStanislaw Gruszka
On rt2800usb, if we do not get TX status from HW, we assume frames were posted and after entry->last_action timeout, we forcibly provide TX status to mac80211. So it's not possible to detect hardware TX hung based on the timeout. Additionally TXRQ_PCNT tells on number of frames in the Packet Buffer (buffer between bus interface and chip MAC subsystem), which can be non zero on normal conditions. To check HW hung we will need provide some different mechanism, for now remove watchdog as current implementation is wrong and not useful.

2016-12-25ktime: Cleanup ktime_set() usageThomas Gleixner
ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.
