Previously we jal to panic which never cleared the tlb fault, so if
on the course of shutdown (like a doshutdownhooks() callback) missed
K2, it would panic again. Fix by setting EPC to panic() and eret.
By default this is off, and only slightly changes the code to load SR when
a temp register is available. This can be used by the platform code to
handle slow to clear interrupts (our case) or to mask off any interrupt
any interrupt at run-time. This can be very useful for embedded platforms
that have less than desirable interrupt properties.
Only the low nibble is defined, and on at least one 3gx (mine) there is an
undefined bit which reads as a one -- bit 6 (0x40). This screwed tctrl_intr()
which would loop forever, thinking it always had new events to process.
which needed to be set at compile time but weren't (to handle the case where
TAR_CMD was set to something other than "tar", eg "gtar". In addition to
the constants being wrong, the wrong directory name was being examined for
its string length.
Add a few comments to hopefully avoid having this problem come back.
stuff
make this all compile with -Wall -Wno-main -Wmissing-prototypes
-Wstrict-prototypes -Werror , also compilable on 1.4.1
label itself as NetBSD/mvme68k instead of "BSD" in bootblock message
move bugcrt.c to libbug, remove bugcrt directory (bugcrt is still built
and used separately to rest of libbug)
convert sboot to use ordinary mvme68 libsa, instead of copying needed
stuff in libc_sa.c
convert to use version info generated by sys/conf/newvers_stand.sh
instead of previous version.c files, add necessary 'version' files
put chiptotime() to separate libsa file (used also by sboot/clock.c)
Thanks to Steve Woodford for help with this. Note that -current build
might be hosed by this change, will be addressed by Steve shortly.
specific hacks:
* Make the bias handling depend on STKB, so it switches correctly for 32-bit
kernels.
* Use the 32-bit stw/ld for 32-bit kernels.
* Add a few `-STKB's that were missed in the previous change.
Reset the scsi bus at attach time, to be sure all devices start in narrow/async
mode.
Defer sync/wide negotiation until after whe have a valid
xs->sc_link->device_softc, so that we can honnor the NOSYNC/NOWIDE quirks.
