pseudo-device rnd # /dev/random and in-kernel generator
in config files.
o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
* rewrite findroot() based on NetBSD 1.2F i386 findoot().
* Rewrite makebootdev() to use struct devnametodevmaj pica_nam2blk[].
Previous changes changed the `devname' char array and findroot()
bot not makebootdev().
* Add prototypes, delint for gcc -Wall.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
* use mips_round_page,mips_trunc_seg() instead of
pica_round_page(),pica_trunc_page().
* discard (unused) return value from TLBUpdate(), and delete
(unused) temporary variable used to hold it.
* fold in netBSD style changes:
``if (foo = bar)'' -> ``if ((foo = bar) != 0)''
* add mips1 vector as well as mips3 vector
* change vector names to make mips1 and mips3 locore entrpoints distinct
* add pmax additions (e.g., old fixes to ktrace code, kernel-TLB_miss
instrumentation)
* update stack traceback code to a newer version of the pmax code.
from arch/mips/mips/locore.S to arch/pmax/pmax/locore_machdep.S.
* Move ARC-specific locore code (vmstat -i counters) to
arch/pica/pica/locore_machdep.S.
* When the mips3 locore support is known to work, both ports can now use
arch/mips/mips/locore.S.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
* include <mips/locore.h> where callbacks into locore are made, to get
prototypes in scope. Cast calls appropriately.
* include <mips/cpuregs.h>, not the old Sprite-derived <machine/machConst.h>.
machConst.h is deprecated.
* dk_establish() must return void, not int.
a boot string for firmware that can do this, such as the SPARC and
the sun3 models. It is currently silently ignored on all other
hardware now, however. The MD function "boot()" has been changed to
also take a char *.
* cut-and-paste all the code for both r2000 (MIPS-I) and r4000 (MIPS-III)
into both the pica and pmax locore.S.
* Change the names of the small segments of vector code that are
bcopied to the machine vector locations, to avoid clashing.
Get rid of the Sprite MachXXX names for the vector code, and
use use mips_r2000_xxx and mips_r4000_xxx instead.
Update the names used in the vector-copying code and trap handlers
to match.
* Most of the rest of the pica locore.S was copied from the pmax
locore.S, and then edited to work on an r4000. The names of
functions and of manifest constants stayed the same, although
both assmbler code and constant values changed.
cut-and-paste such code into contiguous blocks protected by
#if / #endif. Much of the cache and trap-handling code
needs r3000-only register fields, on the r3000, and r4000-only
insns and registers on the r4000.
* change the pmax r2000 exception-handling code to extract a trap
code with the user/kernel bit at 0x20 rather than 0x10.
(r2000s have 4-bit execption codes, r4000s have 5-bit.)
Use the a 16 from-user-space + 16-from-kernel space jump table,
just like on the r4000 pica port.
* add NOPs to the common code where required by the r4000 pipeline
constraints.
* add _C_LABEL() macros to the r4000 locore.
Comitted to provide a snapshot for others to test, and work on a cleaner merge.
* Add a MIPS-I (r3000) exception handler to the Pica locore.S.
Change the names of the masks used to extract the exception code
to the new MIPS_xxx names.
* Rename the vector code from MachException() to
mips_r4000_exception, in both locore and in the init_main()
code that copies it from locore to the exception vector locations.
* Change the locore and C code to use the new MIPS_SR_INT_IE
name for the Status register master interrupt-enable bit.
Similar changes to the pmax equivalents are in progress.
arch/pica/pica/trap.c, a generic mips trap handler
arch/pica/pica/pica_trap.c, a handler for Pica interrupts.
so that the common pmax and pica trap handling can eventually be
merged and moved to arch/mips/mips/trap.c
* Add cast to hardclock when it's used directly as an interrupt handler.
* Add a null-interrupt-establish function, to avoid int vs void lint
in pica/dev/dma.c.
* fix include in pica/include/pccons.h to work with "standard"
kernel-compile include path.
or for which the Pica port is an older revision of the pmax branch.
A merged version with the NetBSD/pmax revision history is in mips/mips/.

- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
