2014-04-16Add generic driver for "NEC PC-9801(*) extension board slot" onKenji Aoyama
LUNA-88K. LUNA-88K{,2} has one or two slot(s) that can attach the extension board designed for PC-9801. This driver provides dedicated mmap(2) and capability for waiting specified interrupt on that slot so that we can use the extension board from userland program. (*)PC-9801 is a Japanese popular personal computer, mainly used in 1980-90's. (see http://en.wikipedia.org/wiki/NEC_PC-9801) ok miod@, and man pages jmc@

2014-04-04Second step of the R4000 EOP errata WAR: when pmap invalidates a page whichMiod Vallat
is currently being covered by the wired TLB entries, flush them, so that, if the process' pc is still running in a vulnerable page, the WAR will reapply immediately and fault the next page.
2014-04-04If the PDC_COPROC call fails, and we are running on a PA 1.1 system, assumeMiod Vallat
the usual 1.1 coprocessor mask, instead of using zero and having every userland process dying with signal 4. The circumstances under which this call fails are unclear and could be tied to specific PROM version (I have tried overzealous stack alignment and other tricks, to no avail). Interestingly enough, the 715/75 system which hits this problem, only triggers it when booting from disk, and never when booting from network. This diff is an ugly bandaid until the problem is better understood. Or maybe it is not worth investigating, seeing that Linux hardcodes the coprocessor mask and never issues PDC_COPROC calls; I wonder what HP/UX does. In my tree for over 18 months; "Looks like a nice hack" deraadt@ 715/75 system provided by Sebastiaan Indesteege, thanks!
2014-04-04It seems that, when the on-board USB controller is an ALI M5237 USB and itsMiod Vallat
interrupt is routed through the ISA PIC, the interrupt is edge-triggered (despite PCI interrupts being level-triggered). Attempt to recognize this and correctly setup the PIC ELCR register to `edge'. This allows ES40 systems (and maybe others, but apparently all the other alpha systems with on-board M5237 correctly route its interrupt as a PCI interrupt) to reliably boot multiuser without suffering from USB interrupt storms (this is especially noticeable when using glass console which, unlike serial console, does not trigger other interrupts to give other devices a chance to run). However, this is not enough yet to allow for proper USB device usage; your mileage may vary. Tested by bluhm@ and me. Putting it early in the release cycle so that regressions on other systems, if any, can hopefully get noticed soon enough.
2014-04-04let device_register match scsi devices to anything hanging off aDavid Gwynne
scsibus. this lets path drivers get matched instead of just sd(4). ask mpath to maybe swap a path with a disk via mpath. ok deraadt@

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.
2014-03-31Including <uvm/uvm_extern.h> is enough, no need for <uvm/uvm.h> or more.Martin Pieuchot
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@

2014-03-30Eliminates struct pcred by moving the real and saved ugids intoPhilip Guenther

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.
