2012-10-08Revamp the sequences for suspend/hibernate -> resume so that the codeTheo de Raadt
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

2012-06-26create new machine/_float.h which is namespace clean. create a newTheo de Raadt
MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.

after hours of tinkering with my frame buffer debugger, here comes color support for tvrx(4) - by making use of all overlay planes. Access to the regular planes remains a mystery, and seems to require a download of microcode into the board first. Still slightly better...
2011-12-21Work-in-progress driver for the HP ``Audio1'' device found on the HP 9000/425eMiod Vallat
(hp300) and the HP9000/705 and 9000/710 (hppa). 8-bit mono, 8KHz, no surprise since it is based upon a digital phone chip. Tested on 425e only so far, and playback only; configured in, but disabled, on hppa kernels until there are positive test reports (I am not sure the interrupt assignment on hppa is correct). And now people no longer can joke about audio on hp300.

2011-11-01Drop support for the HP MMU. It was only found on two hp300 systems (modelsMiod Vallat
320 and 350), which have been unsupported since a bunch of release already, because this annoying MMU does not have TT registers (or if it does, it is not documented) and thus went in the way of PMAP_DIRECT for hp300. In other words: remove a bunch of code which was either #ifdef'ed out or had no chance to run in real life.

2011-08-18Add sti@dio attachments.Miod Vallat
2011-08-18So, it turns out that models 362 and 382 built-in frame buffer only shows upMiod Vallat
in DIO-II space, as a fat device spanning four select codes (i.e. 16MB of memory). This is way too much for an at-most 2 Mpixel 8bit frame buffer, and it turns out that this is because the device provides both a regular DIO-II frame buffer (spanning two select codes) and a regular STI frame buffer (spanning the other two select codes). This commit introduces a straightforward sti@dio attachment to get a working sti(4) and wsdisplay(4) in a ridiculously small number of lines; however the console code needs some changes to avoid duplicating globals. While there, add sti@dio support for the bootblocks, and I couldn't help myself but clean the most rotten parts of them, and try to have them reuse various files in sys/arch/hp300/dev instead of rolling their outdated ones. Tested on a real 382 with the low-resolution frame buffer: sti0 at dio0 scode 132: rev 8.02;129, ID 0x27134CB440A00499 sti0: 382V, 2048x512 frame buffer, 640x480x8 display sti0: 8x16 font type 1, 16 bpc, charset 0-255 wsdisplay0 at sti0 mux 1: console (std, vt100 emulation) Boot blocks updates tested on DIO-II 425t (serial/glass console), SGC 425e (serial/glass console) and 382 (serial/glass console). And will be tested on SGC 425t soon as well.
2011-08-18Fix various lies in comments, extend hex constants to 8 hex digits for easierMiod Vallat
reading, and introduce a define for the DIO-II device size, as reported by the device itself (in quarters of select code span, just to make things more complicated than necessary).
2011-08-18Because model 362 does not have an SGC bus (or a blind, deaf and mute one),Miod Vallat
there is no way we can tell models 360 and 362 apart by probing for an SGC bus, or for a frodo(4) chip since of the `lil' black swan' 3x2 models, only model 382 has frodo. So don't bother trying to tell models 360 and 362 apart, and use a common 36X symbol. No functional change except for useless code removal.
2011-08-18Do not skip 362 and 382 DIO frame buffer select codes; this was writtenMiod Vallat
back when I thought that these devices were showing both in DIO-II and SGC spaces; but, as researched by tsutsui@netbsd, there is nothing in the SGC bus address space (assuming there is SGC bus logic at all) on 3x2.

2011-07-07The drahn memorial bad kernel build fix: prevent blood pressurePhilip Guenthe

that they're implemented consistently in bounds_check_with_label(). Also, per krw's request, change bounds_check_with_label() to return 0 if the checks succeed, and change the drivers to test == -1 instead of <= 0. (Man page update to follow; intentionally omitting arch/vax/mba/hp.c from this commit because it doesn't even build currently and miod@ promises to kill it soon.) ok krw@

2011-07-05Recommit the reverted sigacts change now that the NFS use-after-freePhilip Guenthe

2011-06-26if_downall() cannot be done MI in sys_reboot() because vfs_shutdown()Theo de Raadt
might need network (ie. nfs). Move the call to the MD boot() routines. This cause for boot hangs diagnosed by kettenis.

2011-06-05Move the bufcachepercent setting code to MI locations -- set it to 42%Theo de Raadt

2011-05-30Remove the freelist member from vm_physsegOwain Ainsworth
The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build)

2011-04-18Revert the sigacts diff: NFS can apparently retain pointers to processesPhilip Guenthe
until they're zombies and then send them signals (for intr mounts). Until that is untangled, the sigacts change is unsafe. sthen@ was the victim for this one
2011-04-16Use 'CLR(<buf>->b_flags, B_READ | B_WRITE | B_DONE)' regardless ofKenneth R Westerback
what the previous IO was. Less chance of copy and paste errors. Suggested by miod@.
2011-04-15In days of yore one could arbitrarily whack buffer flags. Those daysKenneth R Westerback
are past. Use CLR() and SET() to modify necessary flags while leaving the flags used by the buffer cache in peace. Should make bufcache code much less confused about the state of the bufs used in reading/writing disklabels. Other such flag abuses no doubt await a visit. Errors in original diff found by miod@. ok beck@ deraadt@
2011-04-15Correct the sharing of the signal handling state: stuff that shouldPhilip Guenthe
be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves to struct sigacts, wihle stuff that should be per rthread (ps_oldmask, SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread until our locking around coredumping is better. Oh, and remove the old SunOS-compat ps_usertramp member. "I like the sound of this" tedu@
2011-04-15Convert the kernel Makefiles to autogenerate dependencies during compilationPhilip Guenthe
using the -MD option to cc, with -MP, -MT, and -MF where needed, converting "make depend" to a no-op. This increases parallelism for those using "make -j" and keeps the dependencies up to date with each compilation automatically. sparc and vax users will need to rebuild gcc with support for the -M[PTF] options before config'ing with this diff.
