which is automatically included during kernel config, and add comments
to individual machine-dependant majors.* files to assign new MI majors
in MI file.
Range 0-191 is reserved for machine-specific assignments, range
192+ are MI assignments.
Follows recent discussion on tech-kern@
- Clean up the way cpu-specific tlb/cache functions are configured
and used.
- Add a workaround for a problem whereby cpu* at superhyway? fails
to probe.
- Print more info about the cpu/cache.
- Move the RESVEC handlers back into generic sh5 code and ditch
the panic stack hack.
- Make the on-chip SCIF device the default console on Cayman.
- Add experimental support for booting via a standalone bootstrap
program (not yet committed) and using the boot parameters passed
in by it.
- Add a few more SH elf constants.
- Tick a couple of items off the TODO list.
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.
The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.
This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.
Per lengthy discussion with Andrew Brown.
- Overhaul the TLB management code such that we now keep track of
the exact TLB slot at which a mapping was inserted, both for user-
space and kernel mappings. This addresses #2 on the TODO list.
- Allocate interrupt handles dynamically from a pool(9) to reduce the
number of TLB misses during interrupt dispatch.
- Fully support evcnt(9) in all interrupt dispatchers.
- sysfpga_sreset()
Hit the soft-reset register to reset the board.
- sysfpga_twinkle_led()
Might as well put the blinkenlight on the Cayman to good use as
a "heartbeat" indicator.
