mpshutdown() used to call acpireset() making it impossible to build
a kernel without archacpi. now, mpshutdown() is a helper function
that only shuts down the application processors that gets used from
mpreset() and acpireset().
the generic machine reset code in exported by devarch's archreset()
function that is called by mpreset() and from acpireset() as a fallback.
so the code duplication that was in mpshutdown() is avoided.
the purpose of checkpages() is to verify consitency of the hardware mmu state,
not to notify on the console that a program faulted. a program could also
continue after handling the note. (this seems to be the case in go programs)
- shorten cpuidprnt so it doesnt have to break line
- addarchfile: complain when running out of entries
- fix range check in rmemrw() (harmless)
- use nil instead of 0 for pointers
- in 9front, the bootargs are in the form: method!device args
- remove redundant and wrong paragraphs regarding tcp booting
- document il boot method
- fix boot and bootrc confusions
this is a new more simple version of the mount cache
that does not require dynamic allocations for extends.
the Mntcache structure now contains a page bitmap
that is used for quick page invalidation. the size
of the bitmap is proportional to MAXCACHE.
instead of keeping track of cached range in the
Extend data structure, we keep all the information
in the Page itself. the offset from the page where
the cache range starts is in the low PGSHIT bits and
the end in the top bits of Page.va.
we choose Page.daddr to map 1:1 the Mountcache number
and page number (pn) in the Mountcache. to find a page,
we first check the bitmap if the page is there and then
do a pagelookup() with the daddr key.
change page cache ids (bid) to uintptr so we use the full
address space of Page.daddr.
make maxcache offset check consistent in cread().
use consistent types in cupdate() and simplify with goto.
make internal functions static.
use nil instead of 0 for pointers.
there is no use for "bootdisk" variable parametrization
of /boot/boot and no point for the boot section with its
boot methods in the kernel configuration anymore. so
mkboot and boot$CONF.out are gone.
move the rules for bootfs.paq creation in 9/boot/bootmkfile.
location of bootfs.proto is now in 9/boot/bootfs.proto.
our /boot/boot target is now just "boot".
expand the list of files specified in bootfs.proto and use them
as dependencies to bootfs.paq rule. this way, bootfs.paq is
regenerated when the to be included files have been modified.
