instead of "pciide", and check one layer farther up in the device hierarchy
for the scsipidev device.
From Manuel Bouyer, tested by me on a up1500 (identical changes to other
ide-booting code).
mv MNT_GONE, MNT_UNMOUNT and MNT_WANTRDWR to this field
additonally add mnt_writeopcountupper and mnt_writeopcountlower fields
in preparation for pending write suspension support work
bump kernel version to 1.6ZD
"/usr/include/machine/varargs.h") by a stub include file which will
emit an error if GCC 3.3 or newer is used and include "machine/varargs.h"
otherwise.
Based on a suggestion by Richard Earnshaw. This fixes PR toolchain/22888
by myself.
- Use the "clz" instruction to pick a run-queue, instead of using the
ffs-by-table-lookup method.
- Use strd instead of stmia where possible.
- Use multiple ldr instructions instead of ldmia where possible.
they use the mini D$.
This results in a small performance boost on xscale platforms, since
flushing the main cache on a context switch won't affect the kernel
stack/pcb.
with the KVA of the newly-wired uarea.
This is useful on some architectures (e.g. xscale) where the uarea mapping
can be tweaked to use the mini-data cache instead of the main cache.
(Note: memcmp/memset improvements also benefit non-Xscale).
memcmp() - Compare 32-bits at a time if possible. Special-case 6-byte
comparisons, for the benefit of the network stack.
memset() - More loop unrolling, plus use of 'strd' instruction,
results in > 100% speedup on Xscale.
memcpy() - Big-endian support, unrolled loops, 'strd/ldrd/pld', plus
special-cases for very common length/alignment combinations
(at least in the kernel). Benchmarks show ~50% improvment on
Xscale.
memmove() - Big-endian support. Use fast memcpy(), above, if the regions
don't overlap. Otherwise unchanged.
userspace). Having them here is both good and bad. Good because they're
close to the actual native ones, bad because it exposes things out
of compat/netbsd32. However, putting the exclusively in the latter
requires a lot of reshuffling in the includes there, so this will
do for now.
