at levels 5 (sound) and 6 (via1) on the Q700.
Raise splhigh when reading and writing registers. It's ugly, but it's
possible that we could get an interrupt from a higher-level source,
causing a re-read of a memory location.
This is not good when, e.g., we are reading the interrupt register.
Ideally, we would just raise splhigh() in ncr53c9x_readregs(), but
that's m.i. code, and it may be expensive on other architectures.
has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that. INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now). This will eventually
change now these maps are locked, as well.
- Make it compile again, with BPF.
- Don't subtract the Ethernet header length from the total packet length.
- Copy the alignment fix from sys/dev/ic/i82586.c (though the m68k shouldn't
really be affected).
directly, call the function pointer (*if_input)(ifp, m). The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary. Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
the child inherits the stack pointer from the parent (traditional
behavior). Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.
This is required for clone(2).
of the buffer you're copying from as the loop interator, not the length
of the buffer you're copying to. Also, rewrite print_single() with
pointer instead of array operators. Appears to correct some ADB-related
`hangs' during autoconfig.
to mac68k_init(), so that we're through frobbing the MMU in special ways
by the time we get there. While it doesn't actually cause a problem with
the current structure of our initialization code, it probably would have
in the future.
had been returning (-1) as an error instead of 0. This is the result of
not keeping up with its i386 ancestor, which it was originally derived
from back in 1993. Re-sync.
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.
When we put a page on the collection list, we must subtract NPVPPG from the
total free count: one for each pv_entry that's free in that page, and one for
each free pv_entry in other pages that we're going to eat by moving the ones
in the page being collected.
