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

correct and unify; ok thib miod

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
|
|
So put back the flushg in pmap_release since at least it hides it
and I can now reproduce.

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
|
|
as per recommended values from Intel documentation.

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

the commit which enabled DEADBEEF* overrides, then values have been
discussed a bit more and improved; reminded by and ok art@
|

for some time. I can't believe it took a re-read for future
functionality plus something I wrote and kjell@ saved from '97
for me to find this.

Remove the workaround.

pieces. Since this is where the "boot both ELF32 and ELF64" behaviour
is turned on for i386, it is quite important.
Bump version numbers too.
Found by ckuethe@; thanks.

bounds_check_with_label() routines as identical as possible without
changing any code. Code nits and adjustments to come.

retreive p_state data as spelled out in the amd64 bios and kernel
developers guide. This code is still a little rough around the edges but
has been tested by myself on a tyan machine and by phessler at theapt
dot org on an HP DL145. This diff also takes a first stab and cleaning up
the acpicpu dmesg spam.

bounds_check_with_label. All callers check for <= 0, so no functional
change.
Feedback from miod@.
ok weingart@
|

both 32- and 64-bit versions can be created (previously only one or the
other could be built for a given boot loader).
Use this to allow the i386 and amd64 boot blocks to boot both ELF32 and
ELF64 kernels (i.e. amd64 boot blocks can now load i386 kernels, and
vice versa). Obviously the system must support LONG mode in order to
successfully run the amd64 kernel once it is loaded.
Advice and discussions from/with dale@ (going back three years). Much
testing nick@ and todd@; thanks.

VM_MAXUSER_ADDRESS before running the loop rather than for every
byte we copy. Saves 4 bytes in locore :)
Similar to how this is done on amd64.

the rare 80386-bases system with enough memory, a 387 FPU, a useable
disk subsystem, and the patience to wait for it to unpack the
distribution .tgz files.
approval from art@ and many others (esp. nick@); ok deraadt@

will check this flag durring probe, meaning that if the machine has APM
ACPI will not attach. This should remove one obstacle on the road to
enabling ACPI by default.

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.

not the other stupid names. that feature was retarded. tested on a few
architectures by a few people
