bpf(4) are different enough so that the split makes sense -- this is necessary
to make bpf(4) cloneable.

with some limited DWARF2 generating .file and .line symbols. Makes it possible

remove pool_cache code. it was barely used, and quite complex. it's
silly to have both a "fast" and "faster" allocation interface. provide
a ctor/dtor interface, and convert the few cache users to use it. no
caching at this time.
use mutexes to protect pools. they should be initialized with pool_setipl
if the pool may be used in an interrupt context, without existing spl
protection.

some radix configurations.

- 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.

more commonly encountered level 4. Do not complain in splassert() in this case
(this is similar to the older vsbus vax machines workaround).

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

same thing. Keep LABELSECTOR and LABELOFFSET and nuke
ALPHA_LABELSECTOR and ALPHA_LABELOFFSET.
Kernel still compiles and boots.
Superfluidity pointed out by deraadt@.

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@
|
|
|
|
|
|
implimentations were simply either missing code, or spacing and such.
setdisklabel() can become MI now.

size which is the REAL DISK SIZE. always. if a driver fails to set
this right, please fix it. agreed with otto and krw

there.

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
|
|
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

to size. tested on almost all machines, double checked by miod and krw
next comes the type handling surrounding these values
|
|
convert version 0 to version 1 disklabels.

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
|
|
bounds_check_with_label() routines as identical as possible without
changing any code. Code nits and adjustments to come.
|
|
bounds_check_with_label. All callers check for <= 0, so no functional
change.
Feedback from miod@.

(and part of setroot); ok miod
|
|
This changes nothing on legacy architectures, but is a bit faster (and simpler)
on the interesting ones.

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.
