- Make setregs() conform to the PowerPC SVR4 ABI, plus one NetBSD
extention (for ps_strings).
- machine == powerpc, not PowerPC.
- Set up machine vector for OpenFirmware.
- Nuke the msgbuf for now; it's not mapped correctly.
- Add missing casts in some asm() directives.
- Enable PSL_RI earlier, and do *not* disable it in fake_spl(), since it
is needed for page faults.
- Some general cleanup.
- Clean up symbol goop - use macros in asm.h where appropriate.
- Add, correct, and generally clean up comments.
- Properly align save areas and temporary stacks.
- Fix the 603 tlb reload code.
- Fix several bogus constants and modifiers.
- Some stylistic changes.
on to the kernel. The boot program passes a boot args string plus
additional information like so:
/pci/scsi@3/disk@0,0:1/netbsd -s<NUL><esym><tag>
The post-<NUL> values are:
<esym> end of the kernel symbol table (32-bits)
<tag> machine type tag (32-bits)
NetBSD/powerpc boot program. Highligts:
- Rearrange a bit so that we can sanely add boot programs for
non-OpenFirmware systems.
- Add support for loading compressed kernels (for booting from
1.44M floppies).
- Add support for loading Elf kernels (Elf is the new standard format
for NetBSD/powerpc). (XXX Don't load symbols right now - the code
to do it is there, but I don't particularly like how space for the
symbol table is allocated; I will revisit this soon'ish).
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
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.
