bridges a chance to work.
Clear variables when changing bootp/bootparams.
Displayed variables are cleaned up so they don't overflow the right of
the screen.
ok: martin
- remove local shrinked memcpy() from bootxx.c bacause
now it's identical with __OPTIMIZE_SIZE__ libsa one
derived from src/common/lib/libc/string/bcopy.c.
Tested netboot from le0 and bootxx + boot from sd0 on SS1+.
implementation of bcopy() needs to become memcpy() as well. The
simpler local implementation is needed so that the boot code doesn't
overflow the available space.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
to avoid unnecessary 64 bit ops which would make binaries larger:
satime_t (currently unsigned int):
numbers in seconds returned by the machine dependent getsecs() function
which are used to measure relative time
saseconds_t (currently int):
numbers in seconds used to specify timeout to network drivers
Per discussion on current-users.
a RAIDframe mirror, apply the RAID boot offset, and try to boot again.
Fixes the problem where disks would be unbootable if partitioned normally
and then converted to RAID 1 without being zeroed first.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
(no prompt) behaviour - it is now possible to "boot net:dhcp -a" and then
say "disk" at the "Boot:" prompt - result should be equivalent to "boot disk",
but the ofwboot was loaded from the network.
While there fix a few minor errors, and one significant: if the "a" partition
should not start at the beginning of the disk, the previous code failed
to read a disklabel. Use the "c" partition now to find the disklabel now
always.
mappings before calling the entry point - change text mappings to read
only and only insert those into the iTLB.
While there remove a few magic constants by information queried from
the firmware.
Same object code is generated (except in prf.c, where putchar argument
type was changed to int to match the prototype and one instrcution
changes accordingly).
strategy() in ofdev.c was not ANSIified in this sweep, b/c that
changes code generated at call sites!
for sparc64 systems. This should fix PR#33987.
Also adapt to the way sparc64 32-bit kernels now report its CPU
architecture -- these still need the sparc64 boot loader, but now
report hw.machine = sparc. Adapt by testing machdep.cpu_arch
instead.
Hints from martin and mrg.
partitions. We do this by checking the NetBSD label to see if the
boot partition is of type RAID. If so, we offset reads from the
disk so that the kernel image can be read.
Note that with this code, sun4 machines (with PROM monitor) will only
boot from RAID if the RAID partition is the first one on the disk.
Tested on a SPARCstation 20, a SPARCstation 2 and a 4/330.
- Map kernel with permanent 4MB pages to ease kernel's life
- Pass mappings down to the kernel as part of bootinfo structure
- Try to detect whether kernel is aware of the new boot scheme or not and
in the former case map the kernel using OpenFirmware and do not pass
bootinfo structure
- Provide -C switch to force compatibility mode if autodetection fails
- While on this, fix PR #25763: If load of default kernel fails, try one by
one those specified in compiled-in list
Much inspired by the bootloader of FreeBSD, with some imported code from there.
