2007-10-16unsigned int is nicer than just unsignedTheo de Raadt
2007-10-13Fix cpu_exit() comments to be more closer to reality.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
2007-10-08enable spdmem where it mattersTheo de Raadt
2007-10-08More simple memset(,0,) -> M_ZERO changes. In this batch move toKenneth R Westerback
size(*p) as the first malloc() parameter where p is declared locally and thus easy to check. Add M_ZERO to gpe_table allocation in acpi.c even though there is no obvious bzero or memset nearby.
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,).
2007-10-06Some archs used memset() rather than bzero(). So duplicate diffKenneth R Westerback
previously applied to other archs deleting a memset() this time. e.g. - 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); - memset(mapstore, 0, mapsize);
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);

2007-09-10Introduce 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.
2007-09-03Remove the pv and pte stealing code. Neither art@ and I like it, theMiod Vallat
theoretical gain of it is close to zero, and our moms told us stealing is bad.
2007-09-03Typos from miod. 'specificed' -> 'specified' in some comments and man page.Kenneth R Westerback

2007-08-25Use ptoa((psize_t)...) and %lu to print memory sizes.Mark Kettenis
2007-08-01Stop making de win over dc on alpha, and include both dc and de on allMiod Vallat
installation media now - it fits. THIS MEANS YOU NEED TO RENAME /etc/hostname.de0 TO /etc/hostname.dc0 BEFORE BOOTING A NEW KERNEL. ok deraadt@
2007-08-01unused, and Miod says this file was superseded by sys/dev/ic/i8253reg.h, soMartin Reindl
remove
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@.

2007-06-20b_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
2007-06-17Eliminate a few straggling 'labelsector' field declarations fromKenneth R Westerback
cpu_disklabel's. 'labelsector' is not used anywhere according to grep. 'go for it' deraadt@
2007-06-17Some alpha (or SRM) designs use level 3 for i/o interrupts, instead of theMiod Vallat
more commonly encountered level 4. Do not complain in splassert() in this case (this is similar to the older vsbus vax machines workaround).
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
2007-06-10No need for two *LABELSECTOR and *LABELOFFSET defines that mean theKenneth R Westerback
same thing. Keep LABELSECTOR and LABELOFFSET and nuke ALPHA_LABELSECTOR and ALPHA_LABELOFFSET. Kernel still compiles and boots. Superfluidity pointed out by deraadt@.
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@
2007-06-09unify DOSPTYP_FAT* code (some architectures missed a filesystem type or two)Theo de Raadt
2007-06-09remove a useless commentTheo de Raadt
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.
2007-06-09annoying spacing glitch which makes the diffs biggerTheo de Raadt

if enabled. ok gwk@
2007-06-08all disklabels read from the kernel now always contain a total sectorTheo de Raadt
size which is the REAL DISK SIZE. always. if a driver fails to set this right, please fix it. agreed with otto and krw
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
2007-06-05use 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@
2007-06-01some architectures called setroot() from cpu_configure(), *way* before someTheo de Raadt
subsystems were enabled. others used a *md_diskconf -> diskconf() method to make sure init_main could "do late setroot". Change all architectures to have diskconf(), use it directly & late. tested by todd and myself on most architectures, ok miod too
2007-05-31Add Bluetooth drivers to GENERIC (not enabled - we still have ways to go)Uwe Stuehler
ok gwk, deraadt
2007-05-31KNF, whitespace and comment rectification to make allKenneth R Westerback
bounds_check_with_label() routines as identical as possible without changing any code. Code nits and adjustments to come.
2007-05-31convert to new .Dd format;Jason McIntyre
2007-05-31Standardize on -1 as the error return value forKenneth R Westerback
bounds_check_with_label. All callers check for <= 0, so no functional change. Feedback from miod@. ok weingart@
2007-05-29start of dumpconf() unification, which one day we can pray will be MITheo de Raadt
(and part of setroot); ok miod
2007-05-29Use atomic operations to operate on netisr, instead of clearing it at splhigh.Miod Vallat
This changes nothing on legacy architectures, but is a bit faster (and simpler) on the interesting ones.
2007-05-29Updated disklabel format to support larger disks and partitions. WeOtto Moerbeek
free room in struct partition by packing fragment size and fragments/block more tighlty and use the resulting space to make offset and size 48 bits. For the disk part we use spare fields in struct disklabel. Kernel converts in-mem copy of the on-disk label if needed, disklabel(8) writes new version. We are careful to only change fields not used by bootloaders. Conception of basic scheme by deraadt. ok deraadt@ krw@
