- Add NetBSD autoconfiguration support.
- Rearrange code slightly to minimize the number of #ifdefs.
- Don't use a structure to access CSRs. Use macros that DTRT for
the NetBSD and FreeBSD cases.
- Deal with alignment contraint on Alpha - add 2-byte padding at the
beginning of the RFA, so that the data will be 4-byte aligned, after
the 14-byte Ethernet header.
Thanks to Matthias Drochner for the testing, and David Greenman for
the feedback on the changes.
kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.
cast if it isn't. (These casts aren't necessarily safe, because of
alignment issues, but they allow the code to compile with prototyped versions
of bus_space_{read,write}_multi_2().)
disconnect from the BIOS
2) when text segment as claimed by BIOS is out of sensible range, punt
completely rather than trying to shrink it to fit the ISA hole. Some
BIOSes would crash with the previous behavior. Some won't have a
working APM with the new behavior, but their BIOSes are broken.
Suggested by Chris Demetriou, with very minor tweaks by me.
operation, since:
- in ipl_enable(), "fr_savep = fr_checkp" is not conditionalized
in the same way (not at all), and
- without this change, it was not possible to enable, disable,
and reenable ipfilter.
ports' boot programs. Also added support for loading gzip'd kernels,
useful for booting from floppy. From Jason R. Thorpe <thorpej@nas.nasa.gov>,
tested by Matthew Green <mrg@eterna.com.au> and Erik Fair <fair@clock.org>.
compliation without DEBUG and/or DIAGNOSTIC happens without errors.
Note that all such initializations in the Alpha port are marked with "XXX
gcc -Wuninitialized". As far as I'm concerned, the one or two times
-Wuninitialized has saved me from problems are worth the (very minor) cost
involved with the initializations, esp. if it's noted why the
initializations are done. This was prompted by PR#3690, from Ted Lemon.
all interrupts which might cause re-entrancy.
Allow virtual addresses which are not managed by the MI VM system to
participate in the PV system.
Remove a few frivoulous TLB cache flushes.
