2014-08-14Unused variable, and more fixes in the attach failure path.Miod Vallat
2014-08-06Correct some dma cleanup error paths.Jonathan Gray
While the index variables were correct the arrays of dma handles they indexed were swapped for rx and tx. As there are a mismatched number of rx and tx descriptors we'd walk off the end of the rx handle array by 30 items. ok deraadt@
2014-07-21boot(9): Reduce annoying style diffsMasao Uebayashi
- Always use either: ((x & RB_XXX) != 0) or ((x & RB_XXX) == 0) in boolean context (mostly if (x), or x ? y : z) - prom_halt() in alpha is confirmed to take int as boolean Converted by coccinelle. No functional change intended.
2014-07-19miod pointed out i forgot which way round casts go.David Gwynne
2014-07-18pass atomic_{cas,swap}_uint a volatile void * instead of a volatileDavid Gwynne
void **. the latter is really hard to cast for, and not what what solaris does. ok kettenis@

2014-07-12Tackle the endian.h mess. Make it so that:Philip Guenther
* you can #include <sys/endian.h> instead of <machine/endian.h>, and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first) * those will always export the symbols that POSIX specified for <endian.h>, including the new {be,le}{16,32,64}toh() set. c.f. http://austingroupbugs.net/view.php?id=162 if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h> currently exports (ntohs, NTOHS, dlg's bemtoh*, etc) * when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and <arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER and betoh* ok deraadt@
2014-07-12Pull in more atomic functions to avoid <sys/atomic.h> trying to use gcc4Miod Vallat
built-ins which aren't available on vax. (A similar diff for m88k is in the pipeline as well)
2014-07-11CPU_BUSY_CYCLE(): A new MI statement for busy loop power reductionMasao Uebayashi
The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To start minimally, use PAUSE on i386/amd64 and empty on others. The name is chosen following the existing cpu_idle_*() functions. Naming and API may be polished later. OK kettenis@
2014-07-11Convert bus_dmamem_map(9) to km_alloc(9) in order to make it fail andMartin Pieuchot
not sleep if the allocator cannot obtain a lock when BUS_DMA_NOWAIT is specified. idea and inputs from kettenis@, ok miod@
2014-07-10Set cold to 1 before executing the DVACT_POWERDOWN handlers when halting orMartin Pieuchot
rebooting a machine, like it is done in the hibernate case. At least some USB host controller drivers rely on this to busy way instead of sleeping. Avoid a panic on macppc with an uhci(4) cardbus plugged in. ok deraadt@, uebayashi@
2014-07-10boot(9): Remove comments about RB_*, "cold", and savectx()Masao Uebayashi
Again remove slightly different comments to reduce diffs. These will be re-added once boot() become MI and its specification is clearly re-defined. OK miod@
2014-07-10boot(): Remove comments about RB_TIMEBAD to reduce diffsMasao Uebayashi
RB_TIMEBAD is documented well enough that the comment is not needed. sparc64 does slightly different and its comment is left with XXX. OK deraadt@ miod@

2014-06-13Fix broken logic in sgec_rxintr() poorly duplicating some of ether_input()Miod Vallat
checks, causing the rx ring pointer to stall as soon as an irrelevant frame is received when the intergace is in bpf+promiscuous or `all multicast' mode. Problem spotted and tracked down to the use of bpf by sebastia@. Hair pulling by me.
2014-05-31Revert previous diff setting cold to 1 on shutdown because it breaks machineMartin Pieuchot
with softraid(4) disks. softraid(4) is the last real consumer of the doshutdownhooks(9) API and it is not trivial to convert its hook to a DVACT_POWERDOWN handler since the latter does not allow to sleep.

pointers.
2014-05-17Lower VUPS value for delay() to behave closer to the intent.Miod Vallat
This is temporary until vax grows code to compute a proper delay const at runtime, but will help a bit, especially on KA46 where cd(4) end up detected as sd(4) due to too short delays.

2014-05-15Move from struct proc to process the reference-count-holding pointersPhilip Guenther
to the process's vmspace and filedescs. struct proc continues to keep copies of the pointers, copying them on fork, clearing them on exit, and (for vmspace) refreshing on exec. Also, make uvm_swapout_threads() thread aware, eliminating p_swtime in kernel. particular testing by ajacoutot@ and sebastia@
2014-05-11Move the increment of uvmexp.softs back to the caller of mi_ast():Philip Guenther
it needs to be done atomicly on some MP archs and we don't have atomic_add_int() everywhere yet. Also, mi_ast() was meant to be inline. noted by miod@

2014-04-18Have each thread keeps its own (counted!) reference to the process's ucredsPhilip Guenther
to avoid possible use-after-free references when swapping ids in threaded processes. "Do I have the right creds?" checks are always made with the threads creds. Inspired by FreeBSD and NetBSD "right time" deraadt@
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@

Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

native size, so eliminate the #defines. ok miod@
2014-03-13get rid of the assumption that the head of the alldevs list is theDavid Gwynne
"mainbus" device. this breaks when mpath is enabled because it attaches before mainbus and therefore takes the head position. have autoconf provide device_mainbus() which looks up mainbus_cd, and use that instead. discussed with deraadt who just wants mpath stuff to move forward despite there being many ways to shine this particular turd.

the chip is always false, so remove this no-op. In fact this list contains the link-layer address as soon as the device attachs. ok miod@
2014-02-09Fix copying of the previous pte entries in grow_p1(). Found the hard way byMiod Vallat
sebastia@, this would only affect processes using more than 512KB of stack.
2014-01-30Move declaration of struct vm_page_md from <machine/vmparam.h> toMiod Vallat
<machine/pmap.h> where it belongs, and compensate in <uvm/uvm_extern.h> by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested on all MACHINE_ARCH but amd64 and i386 (and hppa64).
2014-01-26Attempt to make user changes of keyboard layout a bit more `sticky' on wsmuxMiod Vallat
kernels: - keyboard drivers will now tell wskbd if the keyboard layout they ask for is a default value, or a value they are 100% sure of (either because your kernel has a XXXKBD_LAYOUT option, or because the driver can tell the keyboard layout, e.g. by the country code on USB keyboards which provide it, such as Sun's) - when attaching a keyboard with a non-default layout, the layout will become the default layout of the mux for new keyboard attachments if the mux doesn't have a layout set already. - when changing the keyboard layout of a particular keyboard with an ioctl (i.e. using kbd(8) or wsconsctl(8)), the layout will become the default layout of the mux for new keyboard attachments. ok mpi@
