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.
- Combine initenv() and getenvvars().
- Hardwire some PowerBook internal video addresses, from Takashi Hamada.
- When printing out the machine model/CPU, use the new cputype variable
instead of the Booter's PROCESSOR environment variable.
- Use new ptest040() function code argument (though for now, the MMU is
disabled on the 040).
- Revert previous change in get_physical() that seems to have broken
some machines; use an ADD instead of an OR when determining the PA.
- Some (very minor) style cleanup of asm code.
input operands. This corrects an uninitialized variable warning, and
may also explain some erratic behavior of the MRG ADB; gcc could throw
away the value of the `ticks' variable (but I haven't traced through
any ROMs, myself).
indirect bus code framework) from Jason Thorpe. This allows us to dump
bus_scan() and bus_print(), and move bus_peek() and bus_mapin() to the
NuBus code (since they'll eventually go away, anyway).
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.
to initialize conspa was invalid on non-040 machines, since we don't
know which MMU we're using on those, yet. On the other hand, by the time
we get to check_video() on the 040 machines, the MMU has been disabled.
Compromise: get the video PA in setmachdep() on the 040, and in
check_video() on the others. (This is not optimal. *sigh*)
