2014-04-01Move some duplicated code implementing Linux compatibility APIs and stick itMark Kettenis
in a seperate header file. This will become a dumping ground for similar code. ok jsg@

2014-03-31Slightly better debugging code.Mark Kettenis
2014-03-31Use extent_alloc_with_descr(9) and add a mutex to protect the extent.Mark Kettenis
This should make bus_dmamap_load(9) and bus_dmamap_unload(9) "mpsafe". As a bonus this gets rid of a potential memory allocation in the IO path. ok miod@
2014-03-31Due the virtually indexed nature of the L1 instruction cache on most mipsMiod Vallat
processors, every time a new text page is mapped in a pmap, the L1 I$ is flushed for the va spanned by this page. Since we map pages of our binaries upon demand, as they get faulted in, but uvm_fault() tries to map the few neighbour pages, this can end up in a bunch of pmap_enter() calls in a row, for executable mappings. If the L1 I$ is small enough, this can cause the whole L1 I$ cache to be flushed several times. Change pmap_enter() to postpone these flushes by only registering the pending flushes, and have pmap_update() perform them. The cpu-specific cache code can then optimize this to avoid unnecessary operations. Tested on R4000SC, R4600SC, R5000SC, RM7000, R10000 with 4KB and 16KB page sizes (coherent and non-coherent designs), and Loongson 2F by mikeb@ and me. Should not affect anything on Octeon since there is no way to flush a subset of I$ anyway.
2014-03-31In uvm_fault(), when attempting to map backpages and forwpages, deferMiod Vallat
the pmap_update() to the end of the loop, rather than after each loop iteration - which might not even end up invoking pmap_enter()! Quiet blessing from guenther@ deraadt@
2014-03-31Grab the kernel lock before autoconf. This way device drivers can drop it inMark Kettenis
any context if they feel like it. ok deraadt@, guenther@ (who both suggested we could probably grab it even earlier)
2014-03-31Including <uvm/uvm_extern.h> is enough, no need for <uvm/uvm.h> or more.Martin Pieuchot
2014-03-31Force the detach of all USB devices by disconnecting the root hubsMartin Pieuchot
before suspending the machine. Prior to this commit, devices were logically disconnected after resuming the machine leading to funny races since the controller was reset in between. ok deraadt@
2014-03-31Change the order of operations during a suspend/resume cycle andMartin Pieuchot
call bufq_quiesce() after executing the DVACT_QUIESCE handlers. This should be safe since no disk nor controller drivers have such handler but it will allow us to detach sd(4) devices attached to a USB bus. Another benefit pointed out by kettenis@ is that drivers that need to read a firmware from the disk should be able to do it at resume time in a DVACT_WAKEUP handler. ok kettenis@, deraadt@
2014-03-31Rather than scanning local loop ids sequentially, just ask the chip whichJonathan Matthew
local devices it has logged in to. This will also be useful for hotplug later on.

2014-03-30Eliminates struct pcred by moving the real and saved ugids intoPhilip Guenther
struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@
2014-03-30Close the kernel fd before attempting to load /etc/random.seed, and reopen itMiod Vallat
afterwards, for some prom misbehave if the network interface is opened twice; repairs boot.net operation on at least SS5 PROM v2.21; found the hard way by sebastia@. Crank boot version; verified not to hurt disk boot.

2014-03-29Do not play with the xmapmode register, for its layout seems to differ betweenMiod Vallat
board revisions < 4 (found on Indigo) and >= 4 (found on Indy and Indigo2). Paint the cursor as an inverted glyph, instead of exchanging bg and fg colours (matching the current practice on other frame buffers). Speed-up overlapping copy operations by attempting to perform them in larger chunks whenever possible; this speeds up console jump scrolling.
2014-03-29Kill pflowproto 9, it's unfixable post 2038, a better, standardizedFlorian Obser
option is pflowproto 10. Also it duplicates a lot of code from pflowproto 10 and will get in the way in the future. OK benno@
2014-03-28if you split a 64bit thing into two 32bit halves, it helps to writeDavid Gwynne
half of the source value to both the hi and lo parts. writing both of the source halves to just lo isnt going to work good. found by naddy@. sorry guys.
