| | | | | | | | | | | | protect against multiple entries of a function that handled pending soft interrupts. This seems to have been a mistake made when converting code that used simple lock in the 80321 code which got reused in armv7. arm softintr_dispatch() already has mutexes around invoked callbacks which should be enough. Make the pxa2x0 code work the same way which removes the last remaining simple lock use on arm. ok patrick@
* Switch from PSR_X_bit and X32_bit PSR macro names to just PSR_X.jsg2016-01-319-55/+55
| | | | | This matches FreeBSD and makes things a bit more consistent. Discussed with Patrick.

| | | | | | | miod pointed out that time_second should be compared to 1 not 0 in the md resettodr() functions as it is initialised to 1. ok miod@ deraadt@

| | | | | | | | | | | "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.
* Attempt to make user changes of keyboard layout a bit more `sticky' on wsmuxmiod2014-01-261-2/+2
| | | | | | | | | | | | | | | | | 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@

| | | | | | | | kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

| | | | | | | | | | paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin

| | | | | | | | | | | | | | | | keep: - remove bootconfig parameter passing feature (unused). - unifdef __PROG32 and remove all remains of arm26 code. - remove ARMFPE support (unused). - remove support for ARM2, ARM2AS, ARM3, ARM6, ARM7, ARM7TDMI and StrongARM processor families, and the related silicon bug workarounds (especially the SA-110 STM^ bug). - remove cpu_functions no longer necessary after previous removals. - remove ARM32_DISABLE_ALIGNMENT_FAULTS option (unused). - make FIQ support conditional on option FIQ (unused, but may be eventually). Discussed with drahn@ and jasper@ long ago, I was sitting on this commit for no good reason.

* Hurray! Zaurus apm can now call the activate functions intead of powerhooks.deraadt2010-08-301-4/+11
| | | | | | | | | We call the activate functions at splhigh; unfortunately we cannot suspend a zaurus at splhigh because on resume the clock is hosed. We accept this bug for now... perhaps someone can find it? (The powerhooks remain in place in the drivers, and will be roto-tilled once we all the other powerhook-using architectures have switched over) testing by myself and jakemsr; proof reading by oga

* Prevent the apmd/x races for good.oga2010-03-301-1/+10
| | | | | | | | | | | | | | | | | | | When we hit suspend time, go through all wsdisplays on the system. if they are in mode MAPPED, but not MODE_DUMBFB then if possible do a full vt switch to a !mapped vt, and prevent switching back until resume time. This has to be called from MD code because this involves userland running so that X can run the vt switch signal handler. This way, any case where we are using the "poke registers from userland" model, we will not be on the hardware when we go down, so the kernel can actually handle thing properly. Tested on several acpi laptops (by kettenis@ and ian@), x40 (me and beck@ at LEAST) and zaurus (me). Maybe others, but if so I forgot who at this time.. Idea from deraadt somewhere over the Faroe Islands (I thought of a similar thing myself a while ago). Much prompting from him. Ok and comments miod@

* Rearrange the interrupt handler so that it handlers "error status bits"deraadt2009-09-031-10/+14
| | | | | | | | | | | first instead of trying to push data transfers forward. Also, ensure that DONE interrupts are only un-masked when we are on the last sub-block, and that otherwise we process based on RD_REQ and WR_REQ interrupts coming in. Done with drahn and marex (starting from bizzare workarounds by marex which we could not explain) This appears to make Zaurus SD reads & writes completely reliable, even at very low cpu speeds. ok drahn marex
