* Late spring cleaning of the arm code for old dusty bits we do not want tomiod2011-09-201-5/+1
| | | | | | | | | | | | | | | | 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.

| | | | | traversal code to suspend/resume ok oga kettenis blambert
* 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
* Convert all powerhooks to activate functions, and provide powerhook stubs.deraadt2010-08-305-39/+40
| | | | | | Of note: lcd stubs get pulled up to the parent; zts has to keep track of whether it is in use or not 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
* pxa2x0_mmc.c: Dont read MMC_STAT in intr_done if not neededmarex2009-09-031-5/+2
| | | | | | It is not needed to read MMC_STAT if DPRINTF is empty. OK deraadt
* pxa2x0_mmc.c: optimize the speed of the interrupt handlermarex2009-09-021-14/+11
| | | | | | | This patch also eliminates the bug causing any write to the card to hang the whole controller (partly). OK deraadt@

* Add a two new ioctls to the apm(4) interface.oga2009-02-261-2/+12
| | | | | | | | | | | | | | | | | | | APM_IOC_{SUSPEND,STANDBY}_REQ: This is to fix an issue with apm suspend where a call to zzz suspended the machine immediately, not giving anyone listening for apm events (other than apmd) a chance to deal with the upcoming change. This hit X hard since the introduction of drm, since it needs to have time to idle the 3d engine and otherwise get the device into a recoverable state. Such things are needed until we support modesetting in the kernel. Now, instead of forcing a suspend, using ioctl sends out an event similar to if you had put the lid down, giving all userland applications a chance to reply. tested by sthen@ and beck@, especial thanks to sthen for sitting there while I tried to debug this remotely, I owe him beer. Prompted by and ok deraadt@
* When jumping out of the interrupt handler early, clear conditions we knowmiod2009-02-231-3/+20

* Let the sdmmc adapters tell the sdmmc layer how much sectors they canmiod2009-02-201-1/+3
| | | | | | | | transfer with one command. Build on this and the recent minphys() changes in the sdmmc layer to crank transfers at the maximum possible size instead of a sad DEV_BSIZE. Depending on your controller, this can speed up sdmmc I/O up to 2.5 times.
* rename zaurus_reg.h to machine_reg and rename some of the internal fieldsdrahn2008-11-251-14/+14

* Remove definitions and usage of usb_callout and related macros. These macrosmbalmer2007-06-101-2/+2
