devices (obio_norm) or optional address, HSK, and DMA for 5380-based SCSI
controllers (obio_scsi5380). Update all obio-attached drivers
appropriately.
Also, attach fpu to mainbus, rather than obio.
and declare ssir as volatile. This avoids the problem of lost softints
should a hard interrupt cause a softint to be flagged while we are
clearing a different one.
Idea from atari mtpr.h, modified/optimized by me.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.
- extdms_done is modified by things outside of our direct control;
it needs to be declared `volatile'
- CountADBs() fails when we call it the second time. We can work
around this by telling extdms_init() how many ADB devices we have,
only calling CountADBs() once.
can then access the page table entries directly using user data space with
the MOVES instruction. This should resolve the problem on the Duo 2x0
series with hard hangs in this function.
Warning: do not call any function that accesses user data space (FC $1)
from get_pte()!
- Figure out what CPU we have, rather than assuming the Booter knows,
and set cputype variable accordingly.
- Carefully rearrange the order of various MMU/ATC operations so as to
eliminate possible side effects. Also, re-order the initial bootstrap
code to make clear what various sections of this code do.
- Adjust to combined initenv()/genenvvars() (the latter has assimilated
the former).
- Add a function code argument to ptest040().
- Use symbolic constants from assym.h where appropriate (and defined).
- Some style cleanup.
