DEC dc503 cursor chip) into Decstation 2100,3100 cfattach front-end
and ``machine-independent'' back-end.
pm_ds.c: pmin/pmax cfattach front-end
pm.c: bt478, 503 back-end
pmvar.h: declarations of back-end normal and console attach
entry points.
include files containing model-specific I/O device configuration.
Add more options and devices (ccd, LKM, etc), as appropriate for
documentation and as examples in a "template" GENERIC config file,
even though not all of these work completely yet.
from arch/mips/mips/locore.S to arch/pmax/pmax/locore_machdep.S.
* Move ARC-specific locore code (vmstat -i counters) to
arch/pica/pica/locore_machdep.S.
* When the mips3 locore support is known to work, both ports can now use
arch/mips/mips/locore.S.
wrappers for:
gets.c getenv.c strcat.c strcpy.c
so they compile again (if _KERNEL is defined).
For bootblock space reasons it would be prereable to call the PROM entrypoints
directly, via the macro wappers in de_prom.h, rather than C function wrappers.
* Create arch/mips/Makefile.inc with source list of generic MIPS-cpu
files for tags
* Use mips/Makefile.inc and updated tag list in pmax/Makefile
* Try building bootblocks in arch/pmax/stand.
consistency with the way machdep headers for other things are done.
(the creation of the ecoff_machdep.h files was done on the CVS server, to
keep the RCS logs intact.)
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.
use the pre-autoconfig cold serial-console inititialization entry
points from the bus-specific cfattach front-end code.
* Delete post-autoconfig code to switch from PROM output to kernel
driver for machines with dc serial chips.
cfattach front-end code:
dc_ds for the decstation 2100( pmin), 3100 (pmax), and 5100.
dc_ioasic for the decstation 5000/200 (3max) which does not have a
DEC TC-style IOCTL asic, but is configured as if it did.
* Add pre-autoconfig code initialization of kerenl dc driver console I/O
for remote serial consoles. The hack to use PROM serial I/O until the
dc device is autoconfigured is no longer necessary.
* Add MIPS make variable pointing at $S/arch/mips
* Build locore from $MIPS/mips locore source
* Build locore.o and fp.o (fp emulation) from arch/mips locore source
* Add target and rules to build pmax-specific locore code locore_machdep.o
from $PMAX/pmax/lcore_machdep.S
>* Use `-S' rather than `-x' to remove debugging symbols.
because the pmax toolchain and gcc disagree about what is a "local"
symbol, and ld requires a "-x" to let elf2aout build bootable a.out kernels.
in the branch-emulation code was uninitialized, due to a misplaced #endif.
Remove the relevant #ifdef (macro version of GetBranchDest), and move the
XXX note about r4000 branch targets to the function definition.
serial consoles to the 1.2 branch. Includes:
* dynamically allocated new-config softc
* remove dependencies on Decstation CPU type, use flags in softc instead.
* pass in values for softc flags (q.v.) from parent-specific attach code
* #ifdef out rts/cts flow control support until it's known to work on
200s.
* redo initialization of serial consoles (needs more work).
