2007-10-10Make context switching much more MI:Artur Grabowski
- Move the functionality of choosing a process from cpu_switch into a much simpler function: cpu_switchto. Instead of having the locore code walk the run queues, let the MI code choose the process we want to run and only implement the context switching itself in MD code. - Let MD context switching run without worrying about spls or locks. - Instead of having the idle loop implemented with special contexts in MD code, implement one idle proc for each cpu. make the idle loop MI with MD hooks. - Change the proc lists from the old style vax queues to TAILQs. - Change the sleep queue from vax queues to TAILQs. This makes wakeup() go from O(n^2) to O(n) there will be some MD fallout, but it will be fixed shortly. There's also a few cleanups to be done after this. deraadt@, kettenis@ ok
2007-10-06Simpliest memset(,0,) -> M_ZERO changes. One (caddr *) cast removal,Kenneth R Westerback
otherwise just adding M_ZERO to malloc() and removing the immediately adjacent memset(,0,).
2007-10-02Apply (with slight variants) this elimination of bzero() with M_ZERO:Kenneth R Westerback
- if ((mapstore = malloc(mapsize, M_DEVBUF, - (flags & BUS_DMA_NOWAIT) ? M_NOWAIT : M_WAITOK)) == NULL) + if ((mapstore = malloc(mapsize, M_DEVBUF, (flags & BUS_DMA_NOWAIT) ? + (M_NOWAIT | M_ZERO) : (M_WAITOK | M_ZERO))) == NULL) return (ENOMEM); - bzero(mapstore, mapsize);
2007-10-01More easy bzero() -> M_ZERO. Use 'p = malloc(sizeof(*p) ...' whereKenneth R Westerback
obvious.

2007-09-10Introduce a md pmap hook, pmap_remove_holes(), which is supposed to markMiod Vallat
the holes a MMU may have from a given vm_map. This will be automagically invoked for newly created vmspaces. On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents mmap(2) hints which would end up being in the hole to be accepted as valid, causing unexpected signals when the process tries to access the hole (since pmap can not fill the hole anyway). Unfortunately, the logic mmap() uses to pick a valid address for anonymous mappings needs work, as it will only try to find an address higher than the hint, which causes all mmap() with a hint in the hole to fail on vax. This will be improved later.
2007-09-09uchcom(4) has been verified to work by djm@, so add it to allJonathan Gray
USB capable archs.

2007-08-24Add missing bits for siop@gsc.Mark Kettenis
2007-08-23Add commented-out entry for siop@gsc, the onboard Fast-Wide SCSI on theMark Kettenis
735 and 755.
2007-08-23First stab at a driver for the onboard Fast-Wide SCSI on the 735 and 755.Mark Kettenis
Only partly tested; works fine if there are no devices on the SCSI bus.
2007-08-23Look for STI firmware at the additional address given by the firmware. ThisMark Kettenis
removes the need for the hardcoded address for the internal Visualize EG on the B180L, and makes it work on the C180. Tested on a handful of other models too. ok miod@
2007-08-22Subsequent address ranges start at index 1, not index 0.Mark Kettenis
2007-08-15Add sti@uturn; the C180 has it there. Tested by nick@.Mark Kettenis
2007-08-14Add missing siop@phantomas and siop@uturn attachments. The latter was testedMark Kettenis
by nick@ (who sacrificed a few LVD drives for it). The former was tested on a machine without a drive connected, but there is no reason to expect it not to work.

2007-07-30Shuffle the order in which we look for header files, when doingThordur I. Bjornsson
kernel builds locally this doesnt change much but over NFS this cuts about 12% of the build time on my setup (i386). OK miod@, deraadt@.
2007-07-29Seperate members of "struct pcb" that are accessed using physical addressesMark Kettenis
from thos that are exclusively accessed using virtual addresses and add padding between them to make sure they don't share a cache line. Fixes random crashes on at least PA-8700 and PA-7200 based machines. Without this, the PA-7200 based C110 wouldn't stay up long enough to do an install. ok miod@
2007-07-23There seems to be enough room for rl(4) after all.Mark Kettenis
2007-07-23Add ssio(4) and its com(4) ports; thanks to jsg@ for reminding me.Mark Kettenis

2007-07-15lcd(4); a driver for the front panel LCD display found on the four-digitMark Kettenis
B/C/J-class workstations, and many server systems. This is still work in progress; for now it only displays that the machine is running OpenBSD. Not enabled yet.
2007-07-15Add PDC_CHASSIS_INFO and associated structures.Mark Kettenis
2007-07-15Delay switching to the real serial console until we attach the serial device.Mark Kettenis
The variety of different serial devices is just too big to make a decision up front. This should make the second serial port on four-digit B/C/J-class workstation work as a serial console too. ok miod@
2007-07-14Make sigreturn(2) set the proper space ID for the instruction queue. FixesMark Kettenis
a few more pthreads regression tests. ok miod@
2007-07-14Add bge(4). Tested by Maurice Janssen.Mark Kettenis

appropriately. Make it use irq 5, and rewire lpt(4) to irq 7. ok deraadt@
2007-06-24Crank initial storage for extents a bit. We really should allocate extentsMark Kettenis
using malloc once vm is initialised, but this will do for now. ok deraadt@
