- Compute the number of CPU pipeline cycles per second using the
mc146818.
- Use the COMPARE interrupt for the hardclock interrupt.
- Collapse all interrupt priorities into a single priority, and use
the CPU interrupt inputs to determine the interrupt source (local
device, PCI device, ISA device, etc.)
This allows us to have interrupt sharing.
We now just list the names of such variables in .MAKEOVERRIDES.
When we come to export MAKEFLAGS we quote the value of each exported variable
using :Q, using: ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
The :O:u suppresses duplicate names.
Also modifed Parse_DoVar to re-export MAKEFLAGS whenever .MAKEOVERRIDES
is assigned to so .MAKEOVERRIDES+= PATH will export PATH=${PATH:Q}
to the environment, while .MAKEOVERRIDES= will disable export of VAR_CMD's.
- Set XS_TIMEOUT on a selection timeout condition.
- Do not bother to call AscStartChip() in AscResetChipAndScsiBus()--
just clear the chip status.
- Make sure address is word-aligned in AscWriteLramByte().
Tested on my adv (AdvanSys ABP-9xxUA) with CRW8424S and UMAX SuperVista S-12.
Earlier versions of the system would get stuck trying to recover from error
conditions when the CD-RW drive was in heavy use. I have not seen that
behavior with these small patches.
From Var_Set: We actually want the equivalent of
.MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
clearing the previous value for name is important, since
doing simple duplicate suppression does not handle:
$ make FOO=goo
which then runs a sub-make with FOO=boo
the commands from that sub-make should see just FOO=boo.
via MAKEFLAGS. Instead of appending them directly to .MAKEFLAGS, put
them in .MAKEOVERRIDES (and ensure they are quoted). This is now done
in Var_Set when it exports VAR_CMD's.
Use ExportMAKEFLAGS() to export MAKEFLAGS, using the combined content
of .MAKEFLAGS and .MAKEOVERRIDES (with duplicate supression).
If .MAKEFLAGS is assigned to in a Makefile, ExportMAKEFLAGS is called again.
This allows a line like:
.MAKEOVERRIDES=
to effectively stop the exporting of the command line vars in MAKEFLAGS.
with the correct one referenced by a pointer in the podule structure. This is
in aid of eventually making the netslot and podulebus code a little more
separate from one another.
idle() u area issues:
in nmi_sun4m(), if this is a soft NMI and DDB is configured, setup a trapframe
and pass it to nmi_soft(). in cpu_hatch(), spin until our cpu's flags no longer
have CPUFLG_STARTUP set. then, setup registers and jump to
idle_enter_no_schedlock. in idle(), if MULTIPROCESSOR, always switch to this
cpus idle u. a minor optimisation to cpu_switch().
