First stage is bootxx_ffs (for ffs boot partitions) or bootxx_fd (for bootable
floppy disk). These locate, load, and execute the second stage loader boot.amiga.
The console screen is created and passed to the second stage loader.
The second stage loader uses loadfile() to load the kernel image, which can
be either a.out or ELF format, and can also be compressed. It will load a
kernel file from ffs file systems or the ustarfs used on floppy disks.
one, so that we don't mess up the global count of wired pages by having
the page's wire_count be non-zero when we free the page.
pointed out by Michael Hitch.
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h
uvm_fault_wire(). this allows us to make pt_map non-pageable,
but we need to be careful in pmap_remove() not to attempt to
reference PTEs after the PTP has been freed.
interrupts.
This allows hardclock() to account for the time spent in interrrupts, and
as a side-effect, top(1), systat(1) and others will no more report 0% of
interrupt activity.
mvme68k does that already.
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.
Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
Actually, this is added to the siop2_script; should we ever support another
siopng board that does connect something else to GPREG bit 4, we'll have
to move this to C code and make it optional.
OTOH, by then we'll have switched to the MI driver by then.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.
