sparc:
- move enum vactype and struct cacheinfo into cpu.h
- move the cache flags from cpuinfo.flags into CACHEINFO.c_flags
(this allows the new cache_printf_backend() to see them.)
remove unused CPUFLG_CACHEIOMMUTABLES and CPUFLG_CACHEDVMA.
- align xmpsg to 64 bytes
- move cache_print() into cache_print.h so it can be shared with
cpuctl. it only depends upon a working printf().
- if found, store the CPU node's "name" into cpu_longname. this
changes the default output to show the local CPU not the
generic CPU family. eg:
cpu0 at mainbus0: mid 8: Ross,RT625 @ 90 MHz, on-chip FPU
vs the generic "RT620/625" previously shown.
- for each CPU export these things:
- name
- fpuname
- mid
- cloc
- freq
- psr impl and version
- mmu impl, version, and number of contexts
- cacheinfo structure (which changed for the first time ever
with this commit.)
sparc64:
- add a minimal "cacheinfo" structure to export the i/d/e-cache
size and linesize.
- store %ver, cpu node "name" and cacheinfo in cpu_info.
- set cpu_info ver, name and cacheinfo in cpu_attach(), and
export them via sysctl, as well as CPU ID and clock freq
cpuctl:
- add identifycpu_bind() that returns false on !x86 as their
identify routines do not need to run on a particular CPU to
obtain its information, and use it to avoid trying to set
affinity when not needed.
- add sparc and sparc64 cpu identify support using the newly
exported values.
