that the load addresses in the section array are increasing, and that no
section in the array overlap with each other. IRIX proably makes the same
assumptions, but this has not been tested.
The key point with relocation is to always use the same offset for each
section. Because userland gets only the load address off the first section, it
has to assume that all the remaining sections kept the same offset with
respect to the first section. By using fixed offset instead of finding
some free space for each section, we can eliminate the libX11 load hack.
requirement to build as root on a system with vnconfig.
Use ${KERNSRCDIR} and ${_SRC_TOP_} where appropriate
Remove now-obsolete:
list2sh.awk runlist.sh bootfloppy-common/list
Bootfloppy-*/Makefile: don't need to set DISKTYPE or BLOCK8K any more
Rename bootfloppy-common/Makefile.inc to common/Makefile.bootfloppy
and fdset-common/Makefile.inc to common/Makefile.fdset
This uses makefs instead of vnconfig and disklabel, thus removing the
need for root privileges to build these floppies..
Add common/Makefile.ramdisk, to simplify ramdisk-*/Makefile.
Uses shared ${_SRC_TOP_}/distrib/common/Makefile.crunch and
${_SRC_TOP_}/distrib/common/Makefile.image to even further simply things.
Migrate ramdisk-*/dot.profile to a shared common/dot.profile, which
detects whether it's an install or rescue profile based on the existance
of /sysinst. Remove /dev generation code as init(8) now does that for us.
Migrate common parts of */list to a shared common/list.ramdisk.
Convert ramdisk-*/list to new format used by distrib/common/parselist.awk
Don't bother running pwd_mkdb now that libhack's getpwent parses
/etc/master.passwd instead of /etc/passwd.
Migrate ramdisk-*/mtree.conf to a shared common/mtree.conf, which is now a
new full-path-style specfile.
Remove ramdisk-*/ramdiskbin.conf as it's now automatically generated
from ramdisk-*/list by parselist.awk.
Migrate ramdisk-*/termcap.mini to a shared common/termcap.mini.
Remove unused ramdisk-{small,tiny}/disktab.preinstall.
Use .for loops in kernel-*/Makefile to simply defining mostly-duplicated
targets.
ramdisk-*/Makefile: convert to using common/Makefile.ramdisk
Remove unused ramdisk-*/dot.hdprofile.
comprising of:
Makefile.crunch
build a crunchgen(1)ed binary from the provided lists
Makefile.image
build a tree from the provided lists, and
build an ffs file system image from that tree using makefs(8),
without requiring root privileges
parselist.awk
parse list files generating different output:
crunchgen config
mtree specfile
sh commands to populate a tree
from ../bootfloppy-common/Makefile.inc like the other boot floppies.
it wasn't ustarfs that was broken, it was the broken PAD=yes code in the
latter trashing the last 8k of the kernel...
"pty0 pty1 pty2 pty3" before, for a total of 64 device nodes, we now want
just "pty0" for a total of 62 -- the original commit had "pty0 pty1" for a
total of 124, which ate too many inodes and made "ls /dev" a bit messy.
even for program with a DSO using overlapping load virtual addresses.
The fix is a mean hack, see the comments in irix_syssgi.c. It would be nice to
get uvm_map_findspace() to return the page we suggest instead of the page which
is 16384 bytes away.
of removing the duplicate variables, make sure that any duplicate
variable that has an initial value in libsa also has an initial
value here; this keeps the linker from pulling in the libsa
definition.
