2017-01-17Add missing malloc(9) return value check in athn_node_alloc().Stefan Sperling
ok millert@ tom@
2017-01-12Rename ieee80211_mira_node_destroy() to ieee80211_mira_cancel_timeouts().Stefan Sperling
No functional change. The previous name was chosen at a time when I could not yet anticipate what this function would really end up doing. The new name should make this function's purpose more obvious, especially where it appears at strategic places in driver code.
2017-01-12Finish initial 11n support for athn(4).Stefan Sperling
The heavy lifting was done by damien@ years ago. I didn't even have to figure out what the hardware expects, the code was already there. This driver now supports MCS 0-15 in client and hostap mode. No Tx aggregation and no 40 MHz channels yet. tested by vgross@, bmercer@, tb@, jmc@, Vadim Vygonets, Peter Kay ok bmercer@ tb@ phessler@
2017-01-08Make urtwn(4) use AMRR instead of letting the firmware handle rate scaling.Stefan Sperling
For now this only affects RTL8188EU chips, perhaps because the author of this patch does not own any devices containing any of the other chips (hint hint). Patch by misha aka Mikhail / mp39590 at gmail ok mpi@
2017-01-04better handle empty or full rx rings.David Gwynne
currently re appears to end up spinning on landisk. the most obvious cause of this would be an inability to add entries on the rx ring when we run out of mbufs. cope with this by calling rxeof from the isr when the FIFO_OVERFLOW status bit is set. rxeof in turn unconditionally tries to fill the rx ring, even if it doesnt dequeue any packets off the ring. while here limit the number of entries that can go on the rx ring to 1 less than the size of the ring. a full ring looks the same as an empty ring (cos the producer and consumer are the same in both cases), so avoid letting this happen. ok deraadt@ who hit problems on his landisk and tested this diff

2016-11-16rework re_start and re_txeof to be more like other drivers.David Gwynne
the important change is to no longer account for packets and descriptors separately, instead we just deal with available descriptors on the ring. this allows us to guarantee that oactive will only be set after re_start has queued at least one packet, which in turn guarantees that the chip will interrupt in the future and run re_txeof to clear oactive. without this change it was possible for a call of re_start to almost fill the descriptor ring, followed by a second call that could fail to post a packet because it had run out of descriptors and would then set oactive. if re_txeof ran concurrently it could complete all the previously posted packets without noticing that oactive had been set and therefore needed to be cleared. in that situation oactive would be set, but nothing would be set up to clear it in the immediate future. this fixes a lockup reported by haesbaert.
2016-11-16allocate dmamaps for every descriptor in the tx ring.David Gwynne
previously there was a limit of 64 packets on the tx ring. soon we will use as many descriptors as we want to fill the ring.
2016-11-16dont restrict the number of tx descriptors to what can fit on a cpu page.David Gwynne
2016-11-16move toward having the a tx packet descriptor per tx ring entry.David Gwynne
previously you could have 64 packets on a ring with up to 1024 descriptors. this mismatch makes the accounting for free space complicated and allows for a data race with OACTIVE being set. it will also let us push more packets.
2016-11-16serialise posts to the txstart register.David Gwynne
without this it is possible for re_txeof to let the chip look at and complete tx descriptors that re_start has written to the ring but not accounted for in the software producer index. in this situation no future interrupts may be generated for packets on the ring, and tx will stall. the serialisation is implemented by only doing the writes from tasks via ifq_serialize. this is part of a bigger diff that fixes lockups reported by haesbaert.

2016-10-25mask and unmask the interrupt source in an intx specific intr handler.David Gwynne
it seems devices using levelled intx interrupts need to explicitely ack interrupts by masking and unmasking the source around the completion ring handling. without this completions can be lost, which in turn causes long (permanent?) stalls in the block layer under heavy write load. ive experienced this problem with an intel nvme part that only has intx and msix support. because we dont support msix yet we only use intx on it. it appeared to lock up before this fix. this has been tested on both that intel board and a samsung with msi. this fix was based on work found in code by nonaka

2016-10-02Some HABs reset parts of AHCI_PREG_CMD when AHCI_PREG_SCTL_DET_INITPatrick Wildt
gets set. Therefore, ahci_port_softreset() restores the sate of the former register once the device detection sequence is finished. The device detection code in ahci_pmp_port_portreset() does not restore AHCI_PREG_CMD afterwards, so let it catch up. Apparently, this part was an oversight as ahci_pmp_port_portreset() did not otherwise use "cmd". From Marius Strobl tested by awolk (amd64), bluhm (amd64, i386), myself (amd64, armv7) ok jmatthew@
2016-10-02Some HBAs report NCQ capability despite only supporting one commandPatrick Wildt

2016-10-02Given that ahci_port_alloc() grabs one CCB for use during NCQ errorPatrick Wildt
recovery from the CCB pool sized based on the NCS capability, i. e. number of command slots reported by the controller, it is necessary to pretend at least 2 slots in sc->sc_ncmds for devices without NCQ support. That way, also at least 1 available slot is made available for atascsi(4). Otherwise, controllers having only a single command slot will trigger "no free xfers on a new port" in atascsi(4). Note that pretending 2 command slots is also fine with the abuse of the NCQ error recovery CCB in ahci_port_softreset(). From Marius Strobl tested by awolk (amd64), bluhm (amd64, i386), myself (amd64, armv7) ok jmatthew@
2016-10-02Contrary to e. g. the xHCI specification, the AHCI rev. 1.3 specPatrick Wildt
does not say anything about which type (snoopable/uncached etc.) of bus transactions are issued by HBAs on accesses to the descriptors. Thus, the right assumption would be "classical" concurrent accesses by both CPU/driver as well as hardware to the descriptors and their DMA memory backings respectively, which is also confirmed by actual testing. Consequently, switch to BUS_DMA_COHERENT mappings for said DMA memory as otherwise corruption of descriptors is seen.

2016-09-15all pools have their ipl set via pool_setipl, so fold it into pool_init.David Gwynne
the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);
