2008-02-16Move panic tests under #ifdef DEBUGMiod Vallat
2008-02-16Only create phys_map on systems which need it, and test for phys_map beingMiod Vallat
non-null instead of for a variety of vax_boardtype values in vmapbuf() and vunmapbuf().
2008-01-23Cleanup cn_pri. Change constants to more meaningful names, rather thanJoel Sing
the hp300 related ones currently in use. CN_NORMAL becomes CN_LOWPRI, CN_INTERNAL becomes CN_MIDPRI and CN_REMOTE becomes CN_HIGHPRI. ok miod@

2007-12-28If initializing a frame buffer as glass console fails, instead of an invisibleMiod Vallat
panic (for you ichc fans out there), disable the wscons console and force a console device reselection, which ends up in picking a serial console. This should not happen, but just in case, it's a less rude behaviour.
2007-12-28Explicitely mention we are the console device, when applicable.Miod Vallat
2007-12-28There is no need, and no point, to initialize panicstr here.Miod Vallat
2007-12-18Better probe routine for lcg, now that I found the magic bit on KA46.Miod Vallat
2007-12-15Remove a lot of symbols from the namespace, otherwise sys/sysctl.h andTheo de Raadt
rpc/pmap_prot.h collide.. "struct pmap" from the kernel should not make it out to userland. ok miod
2007-12-09Attach lcspx to SPX option boards on VAXstation 3100. Tested on model 38 (KA42)Miod Vallat
only, should work on model 76 (KA43) as well.
2007-12-09Be more careful when checking for hardware, so as not to attach to SPXMiod Vallat
option boards.
2007-11-30Define NORMAL_C_NOP everywhere.Miod Vallat
2007-11-25libkern, begone. Move to a new mechanism where config(8)'s "file"Theo de Raadt
directive can select between MI and MD versions of these files. At the same time, adjust the boot programs to pick exactly what they need, instead of the 7 or 8 mechanisms previously used. There will be some fallout from this, but testing it all by myself is a ridiculously slow process; it will be finished in-tree. Various developers were very nice and avoided making fun of me when I was gibbering in the corner..
2007-11-25Get rid of the kernel 'libcompat' framework, and instead use conf/files toTheo de Raadt
decide which files must be pulled into the kernel. Also conditionalize the pulling of those files based on the COMPAT_* options.
2007-10-13Do not splhigh() before invoking sched_exit(), sched_exit() will do it better.Miod Vallat
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
2007-10-08A few trailing bzero/memset -> M_ZERO occurrences, cast removal andKenneth R Westerback
size(*p) usage.
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.
2007-09-22M_ZERO -> bzero.Kenneth R Westerback
ok art@
2007-09-17Only the most obvious bzero() -> M_ZERO changes. No cast changes, noKenneth R Westerback
MALLOC/FREE, etc. Just adding M_ZERO to malloc() and deleting an immediately adjacent bzero().
2007-09-15[fF]uther -> [fF]urther in comments and man page. First one spotted onKenneth R Westerback
tech@ by Jung.
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.

2007-09-01Do not include <machine/rpb.h> unless necessary.Miod Vallat
2007-08-01Figure out the host SCSI controller ID on KA48 (VLC) and KA49 (VS4k/9x) fromMiod Vallat

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@.
2007-07-13Do not compile disk_reallymapin() unless it is really needed.Miod Vallat
2007-06-20These drivers were abusing b_cylinder to store device-specific informationMiod Vallat
in strategy(), and were reusing it in start(). I first considered introducing a b_rawblkno field in struct buf, as has been done in NetBSD, to stop this abuse. However, it does not cost more to simply move the device-specific ``was-b_cylinder'' computation to the start() routine. Plus we get type fixes (daddr64_t) for free, although this does not really matter for these pedro-sized devices. Thus we do not need to grow struct buf for these devices which really ought to live in your Attic (and my machineroom, of course). hp300 HP-IB tested, vax mfm not, but the logic is the same.
2007-06-20b_cylinder does not need to be set on the callpath down into drivers.Theo de Raadt
cpu_disklabel can go away, since nothing anymore needs to use it; ok miod
2007-06-20In vunmapbuf(), explicitely remove mappings before invoking uvm_km_free().Miod Vallat
Even if the latter would end up removing the mappings by itself, it would do so using pmap_remove() because phys_map is not intrsafe; but some platforms use pmap_kenter_pa() in vmapbuf(). By removing the mappings ourselves, we can ensure the remove function used matches the enter function which has been used. Discussed and theoretical ok art@
2007-06-17significantly simplified disklabel infrastructure. MBR handling becomes MITheo de Raadt
to support hotplug media on most architectures. disklabel setup and verification done using new helper functions. Disklabels must *always* have a correct checksum now. Same code paths are used to learn on-disk location disklabels, to avoid new errors sneaking in. Tested on almost all cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn
2007-06-14excessive blank lines making the versions differentTheo de Raadt
2007-06-14set the prototype disklabel to version 1Theo de Raadt
2007-06-14do not depend on previous loop variable, use a constant insteadTheo de Raadt
2007-06-12all disksubr.c did their b_flags manipulation differently (and wrong).Theo de Raadt
correct and unify; ok thib miod
2007-06-09The differences in the last non-homogeneous bounds_check_with_label()Kenneth R Westerback
routines (alpha, vax) prove to be not worth keeping. Move bounds_check_with_label() into the MI world. Eliminate unreliable and almost certainly useless checks for overwriting a disklabel. After discussion with deraadt@
2007-06-09by hand i carefully found that all the differences in setdisklabel()Theo de Raadt
implimentations were simply either missing code, or spacing and such. setdisklabel() can become MI now.
2007-06-09typoTheo de Raadt

2007-06-07More bounds_check_with_label homogenization. Fix a couple of typos whileKenneth R Westerback
there. 'so go to it!' deraadt@
2007-06-06now that all partition size/offsets are potentially 64-bit, change theTheo de Raadt
type of all variables to daddr64_t. this includes the APIs for XXsize() and XXdump(), all range checks inside bio drivers, internal variables for disklabel handling, and even uvm's swap offsets. re-read numerous times by otto, miod, krw, thib to look for errors
2007-06-06a fair sprinking of knf, code movement, and sometimes character-by-characterTheo de Raadt
accuracy so that the variious disksubr.c's can be compared easier. setdisklabel() starts taking an int for openmask. ok krw, and read by quite a few other people
2007-06-05bounds_check_with_label() checks for i/o outside of the partition andKenneth R Westerback
for overwriting the disklabel. Reorder some checks so all copies of bounds_check_with_label do the checks in the same order. Order picked by using the currently most popular one. Should be no functional change. "If it's boring, commit it" deraadt@
2007-06-05use six new macros to access & store the 48-bit disklabel fields relatedTheo de Raadt
to size. tested on almost all machines, double checked by miod and krw next comes the type handling surrounding these values
2007-06-02Rename cvtdisklabelv1 -> disklabeltokernlabel. It does more than justKenneth R Westerback
convert version 0 to version 1 disklabels. Suggested by deraadt@. ok deraadt@ otto@
