userland structure size (if passed in).
Use the supplied userland structure size (if passed in) to check if
there is enough room to copyout the next structure.
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics. "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.
- disk_unbusy() gets a new parameter to tell the IO direction.
- struct disk_sysctl gets 4 new members for read/write bytes/transfers.
when processing hw.diskstats, add the read&write bytes/transfers for
the old combined stats to attempt to keep backwards compatibility.
unfortunately, due to multiple bugs, this will cause new kernels and old
vmstat/iostat/systat programs to fail. however, the next time this is
change it will not fail again.
this is just the kernel portion.
with bfd_elf_set_dt_needed_soname(). Fixes the "NEEDED crtend.o"
problem reported on tech-toolchain/current-users.
Problem spotted by Ryo HAYASAKA <ryoh@jaist.ac.jp>.
unmanaged mappings) so we can deal with cache aliases, make sure to
skip unmanaged/wired mappings (added via pmap_kenter_pa()) when doing
things like pmap_page_protect().
move a few bits around and make adding screens after attach time
actually work.
When not booting as console, try to properly set up the hardware to
get a display nevertheless (XXX - does not yet work on my U5).
#if 0 some unused functions planned for future extensions (to make clear
they are unused now)
be32toh produces an unsigned long result, causing a printf argument
mismatch. This is the wrong fix, but I am not going to change the
powerpc macros; fix the powerpc macros and revert my change.
While a hard link to a symbolic link is not ruled out by POSIX-2001,
the ln(1) utility (sans -s) is to perform equivalent to the link(2)
function on its operands, which includes the resolution of symbolic
links in source_file arguments.
While a hard link to a symbolic link is not ruled out by POSIX-2001,
the link(2) interface is to perform normal pathname resolution,
which includes the resolution of symbolic links.
