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@.
|
|
cpu_disklabel can go away, since nothing anymore needs to use it; ok miod
|
|
block/native label as needed rather than keeping it in cpu_disklabel.
Also a number of assorted minor tweaks to reduce the delta to sparc64
disksubr.c.

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

look at how doing it in one architecture gets that code copied to the
derivative architectures... amazing..

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

not to what some bogus disklabel from the past may say (some of which
may have been caused by older openbsd disklabel programs). resolves
issues seen by myself and Markus Lude on sparc/sparc64 machines
|

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
|
|
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.

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.
Suggested by deraadt@.

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.
|
|
(and part of setroot); ok miod
|
|
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.

device_register() function -- even if it does nothing. reduces the
cpp-based blather different between architectures
idea ok'd by miod; tested on all architectures (except a few miod will
need to cleanup because he has them)

as done for DAEs not occuring during interrupts.
Remove the check for unprocessed DAE on return from trap() in eh_common.S,
since this can't happen. As a result, the return-from-trap code becomes
identical on 88100 and 88110 systems.

right now that are supposed to be atomic with respect to interrupts and
SMP: atomic_setbits_int and atomic_clearbits_int.
All architectures other than i386 and amd64 get dummy implementations
since at first we'll be replacing operations that are done with
"a |= bit" and "a &= ~bit" today. More proper implementations will follow
