that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
- 'struct fbsoftc' created, which points to a 'struct fbinfo'
- 'struct fbinfo' for each device is allocated with fballoc()
This means:
- Console device doesn't get different 'struct fbinfo' at attach
- Console device doesn't get initialized twice
- Color rcons now works
- The current Xserver MUST BE REBUILT.
routines now reside in locore.S. No functional difference is expected.
- Replace abused splx() abuse with _splset() to change MIPS processor
interrupt mask bit. 'mips/trap.c' side will be fixed soon.
so that devices which must allocate DMA memory in this range (e.g.
PixelStamp graphics boards) have a better chance of doing so, without
an awful hack.
bootinfo record to 1kB (we are using less than 200 bytes now) so that it
doesn't run into addition PROM memory.
At 0x8001f00 the bootinfo record was stomping on some memory used by the
SFB cards for font information.
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
