For one-liners, Lst_ForEach creates a lot of overhead, both at runtime
and for reading and understanding the code.
In this simple case where the structure of the traversed nodes is not
modified, a simple loop is enough. This avoids a lot of conversions to
void * and thus prevents type mistakes.
function. Call in from pmap_bootstrap() for the boot CPU, and
from cpu_hatch() for secondaary CPUs.
- Eliminiate the dedicated I-stream memory barrier IPI; handle it all from
the TLB shootdown IPI. Const poison, and add some additional memory
barriers and a TBIA to the PAUSE IPI.
- Completly rewrite TLB management in the alpha pmap module, borrowing
somoe ideas from the x86 pmap and adapting them to the alpha environment.
See the comments for theory of operation. Add a bunch of stats that
can be reported (disabled by default).
- Add some additional symbol decorations to improve cache behavior on
MP systems. Ensure coherency unit alignment for several structures
in the pmap module. Use hashed locks for pmap structures.
- Start out all new processes on the kernel page tables until their
first trip though pmap_activate() to avoid the potential of polluting
the current ASN in TLB with cross-process mappings.
comment explaining why we don't need to act on IDLE+REMOTE.
- cpu_signotify(): Move to machdep.c, and if we're asked to notify
an LWP running on another CPU, send an AST IPI to that CPU. Add some
assertions.
- cpu_need_proftick(): Move to machdep.c, add some assertions.
To work around objcopy and ld now being unable to create a EABI5 object
from a binary, use the assembler directive .incbin in inline assembly
to pull in the firmware blob.
This also probably makes TEGRA210_XUSB_BIN_STATIC actually work.
a mutex twice, and that upsets LOCKDEBUG. But instead of seeing a
proper message about it, the output happens before the PROM console
interfcace is initialized, we would end up with a translation fault
back into SRM.
This occurred in the posix1.mk test, even though it is disabled in
unit-tests. But in tests/usr.bin/make it still runs. There, it should
have produced an "expected failure" but crashed instead.
The archive-suffix test is the stripped-down version of the posix1 test.
In SuffParseTransform, the parameter names have been renamed to make the
"side effects" comment redundant.
In Suff_AddSuffix and Suff_AddLib, the parameter has been made const.
In SuffRemoveSrc, the unused variable has been removed, and the return
type has been fixed.
