- header and stub .c file for fasttrap module. It's not supported on
MIPS yet, but there is no way to disable support completely
- Do as amd64 trying to limit allocated memory
CTF format is not cross-platform by design, e.g. it is not guaranteed
that data generated by ctfconvert/ctfmerge on one architecture will
be successfuly read on another. CTF structures are saved/restored
using naive approach. Roughly it looks like:
write(fd, &ctf_struct, sizeof(ctf_struct))
read(fd, &ctf_struct, sizeof(ctf_struct))
By sheer luck memory layout of all type-related CTF structures is the same
on amd64/i386/mips32/mips64. It's different on ARM though. sparc, ia64,
powerpc, and powerpc64 were not tested. So in order to get file compatible
with dtrace on ARM it should be compiled on ARM. Alternative solution would
be to have "signatures" for every platform and ctfmerge should convert host's
reperesentation of CTF structure to target's one using "signature" as template.
This patch checks byte order of ELF files used for generating CTF record
and makes sure that byte order of data written to resulting files is the same
as target's byte order.
Note that this driver additionally probes some device IDs for the most
part not know to other MPT drivers, if at all. So rename the macros not
present in mpi_cnfg.h to match the naming scheme in the latter and but
suffix them with a _FB in order to not cause conflicts.
- Like mpt_set_config_regs(), comment out mpt_read_config_regs() as the
content of the registers read isn't actually used and both functions
aren't exactly up to date regarding the possible layouts of the BARs
(these function might be helpful for debugging though, so don't remove
them completely).
- Use DEVMETHOD_END.
- Use NULL rather than 0 for pointers.
- Remove an unusual check for the softc being NULL.
- Remove redundant zeroing of the softc.
- Remove an overly banal and actually partly incorrect as well as partly
outdated comment regarding the allocation of the memory resource.

Unfortunately, the ABI was broken upstream for the 4.2 release, which we
imported. We then shipped the broken version for several years and certain
ports (e.g. libobjc2) depend on it, so we're stuck with it for now...
We should revisit this for 10.0, since we're allowed to break the ABI then, but
until then we should keep the ABI we shipped with 8.x and 9.x.

appropriate state handling takes place, not doing so results in the

Because the driver is obtained from upstream, we don't want to modify
it; just silence the warning instead, it is harmless.

Because the utmpx interface is generally not required to be thread-safe,
but it is nice to have, if easy to do so. Therefore don't make a mess
out of the code and only use it if __NO_TLS is not defined.
KLD is preloaded with loader(8) and leads to infinity loops.
Also do not return EEXIST error code from MOD_LOAD handler, because
we have undocumented(?) ability replace kernel's module with preloaded one.
And if we have so, then preloaded module will be initialized first.
Thus error in MOD_LOAD handler will be triggered for the kernel.
