to the L1 table and a virtual address, and no pointer to the L2 table.
The L2 table will be looked up by pmap_map_entry(), which will panic
if the there is no L2 table for the requested VA.
NOTE: IT IS EXTREMELY IMPORTANT THAT THE CORRECT VIRTUAL ADDRESS
BE PROVIDED TO pmap_map_entry()! Notably, the code that mapped
the kernel L2 tables into the kernel PT mapping L2 table were not
passing actual virtual addresses, but rather offsets into the range
mapped by the L2 table. I have fixed up all of these call sites,
and tested the resulting kernel on both an IQ80310 and a Shark.
Other portmasters should examine their pmap_map_entry() calls if
their new kernels fail.
and let pmap_map_chunk() lookup the correct one to use for the
current VA. Eliminate the "l2table" argument to pmap_map_chunk().
Add a second L2 table for mapping kernel text/data/bss on the
IQ80310 (fixes booting kernels with ramdisks).
there are other architectures (e.g. IA64) which also use PXE.
* Get the console right in pxeboot, from Andreas Gustafsson.
* Add a "com0" version of pxeboot, to address the same issue that
biosboot_com0 addresses.
These are the same values that the hp300 port uses (lesser hp300s
have roughly the same memory constraints as "lesser" vaxen), and
bumping them allows us to run a statically linked ELF groff(1).
disable_intr, enable_intr, disable_interrupt, enable_interrupt,
disable_ext_intr, enable_ext_intr.
New functions:
for external interrupt:
_cpu_intr_suspend and _cpu_intr_resume.
for exception:
_cpu_exception_suspend and _cpu_exception_resume.
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
