2017-07-15Get rid of the device reset hack in iwm_newstate_task().Stefan Sperling
Instead, maintain firmware state in accordance to the current net80211 state by adding/updating/removing MAC config, PHY->MAC binding, and the station in the firmare station table (we only add the AP to this table). By eliminating the iwm_stop() call from iwm_newstate_task(), this change prepares future work on fixing races between ioctls and tasks scheduled by this driver. There's a known new occasional fatal firmware error which results in the message "iwm0: could not remove MAC context (error 35)" I expect to fix this soon. tested by tb@ on 7265, by jcs@ on 8265, and by myself on 7260/7265/8260 ok mpi@ tb@

2017-07-14Reduce the number of CAS loops from ludicrous to ridiculousMike Belopuhov
Now that the source of the delay with releasing grant table entries has been identified and fixed the number of attempts to CAS entry flags can be substantially reduced and while it's decreased by a factor of 100000, it should go down at least a 100 more in the future.
2017-07-14Silence the interrupt source until the interrupt task has done its jobMike Belopuhov
This small change significantly improves performance under load and halves the number of received interrupts.
2017-07-14Support out-of-order TX completion notificationsMike Belopuhov
Apparently, just like the disk interface, the network backend may post TX completions out-of-order, i.e. the ring position doesn't determine which descriptor is being completed and the code must look at the response id inside the completion message. It might seem obvious, but since networking hardware doesn't usually work this way, it was something that has been overlooked. Based on instability reports from Kirill Miazine <km at krot ! org>, thanks!

the si_code is SEGV_ACCERR after memory access with wrong permissions has triggert a SIGSEGV. Adapt the behavior of i386 and amd64 kernel. Remove the useless code that changed error from EACCES to EFAULT in amd64. Also convert variable name rv to errno in i386 to make it look like amd64. OK kettenis@

controller for the inteldrm(4) driver. If wscons(4) provides backlight control, prefer ir over raw hardware control and attach it to LVDS, eDP and DSI connectors which are the connector types typically connected to laptop screens.
2017-07-12Get rid of ICMPV6CTL_ND6_DRLIST and ICMPV6CTL_ND6_PRLIST sysctlsFlorian Obser
With this we can also get rid of in6_prefix and in6_defrouter. They are meaningless, the kernel no longer tracks this information. Pointed out by & OK mpi
2017-07-12Tweak txp to avoid ifq_deq_begin/commit/rollbackMike Belopuhov
Setup the transmit ring the way FreeBSD driver does giving each descriptor a 16 fragment chain and revamp the start routine to use m_defrag for long chains and avoid the dequeue begin/commit/ rollback dance. OK dlg

Hyper-V and Xen have varying support for detaching emulated IDE devices ranging from none on Hyper-V to only IDE disks but not CDROM (Xen). The quirk mechanism provides a way of enforcing the desired behavior. With suggestions and OK kettenis, tedu, mlarkin
2017-07-12Reorganize separate configuration fields into per-CPU structsVisa Hankala
to compact the data indexing. This additionally improves the cache locality of the data.
2017-07-12Invalidate read-ahead buffers when read shortMike Belopuhov
Buffercache performs read-ahead for cluster reads by extending the length of an original read operation to the MAXPHYS (64k). Upon I/O completion, the length is trimmed and the buffer is returned to the filesystem and the remaining data is cached. However, under certain circumstances, the underlying hardware may fail to do a complete I/O operation and return with a non- zero value of the residual length (i.e. data that wasn't read). The residual length may exceed the size of an original request and must be re-adjusted to uphold the contract with the caller, e.g. the filesystem. At the same time, read-ahead buffers that cover chunks of memory corresponding to the residual length must be invalidated and not cached. Discussed at length during d2k17, ok tedu

2017-07-10make malloc(9) mpsafe by using a mutex instead of splvm.David Gwynne
this is almost a straightforward change of spl ops with mutex ops, except the accounting has been shuffled around. memory is counted as used before an attempt to allocate it from uvm is made to prevent overcommitting memory. this is modelled on how pools limit allocations. the uvm bits have been eyeballed by kettenis@ who says they should be safe. visa@ found some nits which have been fixed. tested by chris@ and amit kulkarni ok kettenis@ visa@ mpi@

2017-07-06Our website says that socppc was discontinued after 5.8 (thanks toIngo Schwarze
tobiasu@ for pointing that out), but the manual pages are still installed. I have no idea how to properly tedu an architecture, so deleting the dead .Xr to boot_socppc(8) is all i'm doing in this respect.
