sc_link.openings is greater than 34. Encountered by Sigi Rudzio on his Blade 2500, who kindly did some testing to discover that the answer is 34, not 42. Nuke some whitespace on the way by.

2020-04-21Work around FIFO_UNDERRUN (0x84) Tx errors being reported by iwn(4) firmware.Stefan Sperling
When this error occurs, it tends to occur multiple times in a row. Affected frames are lost and never get transmitted, and traffic stalls for a while. I don't understand what is causing this. I have found that it only occurs if we ask the firmware to use its multi-rate retry table. If we send frames at a fixed rate, it does not happen. So this can be used as a workaround until the real problem is understood. Since this error is particularly problematic with block ack, use a fixed Tx rate for aggregation queues for now. All subframes contained in an aggregate are always sent together at the same rate anyway. ok mpi@

2020-04-20Increase the completion queue size to prevent overflow. Under reasonablyJonathan Matthew
unlikely circumstances - lots of single-fragment packets being sent, a significant number of packets being received, while the interrupt handler was unable to process the completion queue - the completion queue could overflow, which would result in the interface locking up. ok dlg@

the end of it, rather than after. Now we can actually allocate queues big enough to need multiple mailboxes. ok dlg@

development that I forgot about, but turns out to be a potential race with the actual interrupt handler. ok dlg@

2020-04-19Move logic to change brightness level in reasonable steps from acpivout(4)Mark Kettenis
into wsdisplay(4). This code is now exposed through wsdisplay_brightness_{step,zero,cycle} functions that can be called by any driver that handles brightnes "hotkeys". These functions take a wsdisplay(4) device pointer as their first argument, which should be provided if a clear association between events and a particular display exist. This is used in wskbd(4). Otherwise NULL can be passed and the code will direct the request at the first wsdisplay(4) that implements brightness adjustment. Tested by many. Fixes brightness keys on x395 and other thinkpads with AMD graphics. ok patrick@

2020-04-19Add bcmpcie(4), a driver for the PCIe controller found on the Raspberry Pi 4.Mark Kettenis

2020-04-13Fix a recently introduced iwn(4) problem where the link gets stuck sinceStefan Sperling
every CCMP encrypted frame is discarded by the AP as a replay. This happened because of CCMP frames with out of range PNs sent by hardware. It seems iwn firmware doesn't like it if we reset the Tx scheduler slot for a frame which is still within the firmware's block ack window, even if the frame has already been ACKed. So frames now get cleared off the Tx queue only when the block ack window has moved past them, which is good enough and seems to prevent the problem. Problem reproduced and fix tested by both myself and jca@
2020-04-12Turn those spinlock and seqlock inline functions to macrosJeremie Courreges-Anglas
They're macros on Linux because they save state in their flags parameter. Turning them to static inline functions creates a lot of -Wuninitialized warnings, so just use macros which set their flags argument. ok kettenis@
2020-04-12Add support for the _CCA method. This method indicates whether DMA isMark Kettenis
cache-coherent or not. To implement this, acpi(4) gets two bus_dma tags and passes the appropriate one when attaching devices based on _CCA. On i386/amd64, where for all practical purpose DMA is always cache-coherent, the two tags are the same. But on arm64 they are distinct. ok patrick@
