| * | staging: comedi: cb_pcidas: Allow 2-channel commands for AO subdeviceIan Abbott2020-10-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "cb_pcidas" driver supports asynchronous commands on the analog output (AO) subdevice for those boards that have an AO FIFO. The code (in `cb_pcidas_ao_check_chanlist()` and `cb_pcidas_ao_cmd()`) to validate and set up the command supports output to a single channel or to two channels simultaneously (the boards have two AO channels). However, the code in `cb_pcidas_auto_attach()` that initializes the subdevices neglects to initialize the AO subdevice's `len_chanlist` member, leaving it set to 0, but the Comedi core will "correct" it to 1 if the driver neglected to set it. This limits commands to use a single channel (either channel 0 or 1), but the limit should be two channels. Set the AO subdevice's `len_chanlist` member to be the same value as the `n_chan` member, which will be 2.

* / wimax: move out to stagingArnd Bergmann2020-10-2941-0/+15257
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no known users of this driver as of October 2020, and it will be removed unless someone turns out to still need it in future releases. According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there have been many public wimax networks, but it appears that many of these have migrated to LTE or discontinued their service altogether. As most PCs and phones lack WiMAX hardware support, the remaining networks tend to use standalone routers. These almost certainly run Linux, but not a modern kernel or the mainline wimax driver stack. NetworkManager appears to have dropped userspace support in 2015 https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org site had already shut down earlier. WiMax is apparently still being deployed on airport campus networks ("AeroMACS"), but in a frequency band that was not supported by the old Intel 2400m (used in Sandy Bridge laptops and earlier), which is the only driver using the kernel's wimax stack. Move all files into drivers/staging/wimax, including the uapi header files and documentation, to make it easier to remove it when it gets to that. Only minimal changes are made to the source files, in order to make it possible to port patches across the move. Also remove the MAINTAINERS entry that refers to a broken mailing list and website.

| * PCI/PM: Rename pci_dev.d3_delay to d3hot_delayKrzysztof Wilczyński2020-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI devices support two variants of the D3 power state: D3hot (main power present) D3cold (main power removed). Previously struct pci_dev contained: unsigned int d3_delay; /* D3->D0 transition time in ms */ unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */ "d3_delay" refers specifically to the D3hot state. Rename it to "d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for Specifying Device Readiness Durations" in the PCI Firmware spec r3.2, sec 4.6.9. There is no change to the functionality.

| * | | dma-mapping: introduce DMA range map, supplanting dma_pfn_offsetJim Quinlan2020-09-171-2/+8

It subsumes the role of "dev->dma_pfn_offset" which was only capable of holding a single uniform offset and had no region bounds checking. The function of_dma_get_range() has been modified so that it takes a single argument -- the device node -- and returns a map, NULL, or an error code. The map is an array that holds the information regarding the DMA regions. Each range entry contains the address offset, the cpu_start address, the dma_start address, and the size of the region. of_dma_configure() is the typical manner to set range offsets but there are a number of ad hoc assignments to "dev->dma_pfn_offset" in the kernel driver code. These cases now invoke the function dma_direct_set_offset(dev, cpu_addr, dma_addr, size).

The driver have to ensure that all the queues contain data and the device choose the right queue to send. The things starts to be more difficult when the bandwidth of the bus is lower than the bandwidth of the WiFi. The device quickly sends the frames of the highest priority queue. Then, it starts to send frames from a lower priority queue. Though, there are still some high priority frames waiting in the driver. To work around this problem, this patch add some priorities to each queue. The weigh of the queue was (roughly) calculated experimentally by checking the speed ratio of each queue when the bus does not limit the traffic: - Be/Bk -> 20Mbps/10Mbps - Vi/Be -> 36Mbps/180Kbps - Vo/Be -> 35Mbps/600Kbps - Vi/Vo -> 24Mbps/12Mbps So, if we fix the weigh of the Background to 1, the weight of Best Effort should be 2. The weight of Video should be 116. However, since there is only 32 queues, it make no sense to use a value greater than 64[1]. And finally, the weight of the Voice is set to 128. [1] Because of this approximation, with very slow bus, we can still observe frame starvation when we measure the speed ratio of Vi/Be. It is around 35Mbps/1Mbps (instead of 36Mbps/180Kbps). However, it is still in accepted error range.

Thus, when a Block Ack session is restarted, the reordering buffer is not flushed and the received sequence number is not contiguous. Therefore, mac80211 starts to wait some missing frames that it will never receive. This patch disables the reordering buffer for old firmware. It is harmless when the network is unencrypted. When the network is encrypted, the non-contiguous frames will be thrown away by the TKIP/CCMP replay protection. So, the user will observe some packet loss with UDP and performance drop with TCP.

However, it also strip IV from the frame (don't ask me why). So, with the current code, mac80211 detects a corrupted frame and it drops it before it handle the MMIC error. The expected behavior would be to detect MMIC error then to renegotiate the EAP session. So, this patch correctly informs mac80211 that IV is not available. So, mac80211 correctly takes into account the MMIC error.
