Otherwise the compiler may reorder these around loads and stores,
which mostly defeats the purpose. `asm volatile' just ensures the
instruction isn't _deleted_; it may still move around.
define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd.
Field and flag name aligned with OpenBSD.
This does not constitute a functional or ABI change, as the field location
and size, and the value placed in that field, are the same as the previous
code, but we're bumping __NetBSD_Version__ so 3rd-party module source code
can adapt, as needed.
NetBSD 9.99.89
both as standalone drivers for legacy framebuffer console, or parents of
wskbd(4) and wsmouse(4), respectively. For the latter, be explicit about
using "wskbddev" and "wsmousedev" interface attributes for children.
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
instead of fixing to 32KB.
Old 32KB limit comes from
(1) all R_68K_PC16 symbols get relocated, and
(2) all values in our relocation table for R_68K_32 symbols fit within
16-bit integer.
(1) is already checked in the code. Assertion for (2) is added, but this
limit is satisfied with sufficient margin at the moment. If it is not the
case in the future, we may need to change format for relocation table.
- T_ZERODIV is integer divide by zero. Therefore, ksi_code should be
FPE_INTDIV, not FPE_FLTDIV.
- Set ksi_addr for SIGTRAP. Also, set TRAP_BRKPT or TRAP_TRACE to
ksi_code appropriately.
This fixes some tests in lib/libc/sys and lib/libc/gen.
XXX
Apply similar fixes to other m68k ports.
