Audio-related stuff is left almost intact.
* support audiocs at ebus playback and capture
tested on krups and u5 (thanks, martin)
* make first attempt at supporting audiocs at sbus capture
* nb: full-duplex is not tested
* while here, fix CSAUDIO_MONITOR_MUTE to be of CSAUDIO_MONITOR_CLASS
i.e. outputs.monitor.mute -> monitor.monitor.mute
Ok by pk, eeh.
* Use BUS_ADDR() where appropriate to encode I/O space and physical
address offset into a `bus_addr_t' value.
* Drop obio_bus_map() since it's now completely equivalent to bus_space_map()
* Use bus_space_map2() to map device space at a fixed virtual address.
* Remove the virtual address argument from sbus_sbus_addr()
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS

Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).
locations. If passed NULL, the old behaviour using bus_space_{read,write}_1()
is used. Otherwise, all access to the chip goes via the MD functions.
This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is not
directly addressable.
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
the information provided by the loader if possible (defaulting to `end').
If the DDB symbols aren't needed, `kernel_top' is adjusted in
autoconf:bootstrap() before calling pmap_bootstrap(). It will also
preserve the bootinfo data (if passed by the loader) for non-DDB kernels.
While we're here, enable RAIDframe (and RAID_AUTOCONFIG) by default for
architectures that I'm comfortable can deal with it being on by default.
Also: bump the number of 'raid' devices from 4 to 8, since 4 seems to
be insufficient in practise.
translation, get rid of sbus_bus_addr. Since sbus_bus_addr is used by
framebuffer drivers that are shared with sparc64 we cannot just change
the callers to use BUS_ADDR() w/out coordinating the change with
sparc64 that uses a different calling protocol, so stub our
sbus_bus_addr to just return BUS_ADDR.
which will cause the values of tf_pc and tf_npc set here in cpu_fork()
to be restored and used to return to user space from sigreturn() eventually
(before that the tf_pc and tf_npc set in sendsig() will be used in
proc_trampoline()).
Also, the fork system call never uses the SYSCALL_G2RFLAG shortcut, so drop
the code handling that.
(instead of `tf_npc') contains the user-space return address. This ensures
entering the signal trampoline code correctly in case we take handled
signal during child_return().
In a lot of places (like pmap &c) we want it to be treated as SUN4M.
But since various low-level things are done very differently from
normal sparcs (and since for now it requires a relocated kernel
anyway), the MSIIEP kernels are not supposed to support any other
system. So when MSIIEP is defined - insist on SUN4M defined and SUN4
and SUN4C not defined.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup
build features (such as ross's DEBUGLIST) can easily be applied to all
ports. This should reduce the complexity of each port's kernel
Makefile considerably. Line counts:
227 arch/i386/conf/Makefile.i386.orig
98 arch/i386/conf/Makefile.i386
227 arch/alpha/conf/Makefile.alpha.orig
99 arch/alpha/conf/Makefile.alpha
219 arch/sparc/conf/Makefile.sparc.orig
102 arch/sparc/conf/Makefile.sparc
215 arch/vax/conf/Makefile.vax.orig
102 arch/vax/conf/Makefile.vax
253 conf/Makefile.kern.inc
Roll i386, alpha, sparc, and vax over to the new build machinery.
- Make the 32-bit SPARC profile support work with the GCC 2.95.3
SPARC ELF compiler, which uses a different name for mcount.
- Make the 64-bit SPARC profile support header look more like the 32-bit
SPARC header (no functional change -- 64-bit SPARC already used the
correct mcount name).
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.
Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.
