fixed DMACSR_BITS definition to reflect DMACSR_READ bit renaming
1999-08-28 09:42:44 +00:00
3c215084bc
discovered the purpose of another bit in the dma control register.
...
DMACSR_READ is now a CSR status bit which can be used to know if current transfer is
from cpu to device.
the old DMACSR_READ bit is renamed DMACSR_SETREAD. This is a control bit that tells
the dma transfer to be from cpu to device.

Unlike in an i386 a.out assembler, where in an .align n directive n is meant
...
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.
Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.

two changes to prevent the kernel's pmap from being locked recursively
...
via interrupts:
(1) pmap_map_ptes() and pmap_unmap_ptes() don't need to do anything to
map the kernel's pmap, since all pmaps contain the kernel's PTPs.
this fixes interrupt-context calls to pmap_extract().
(2) pmap_kenter_*() and pmap_kremove() no longer adjust the kernel pmap's
resident and wired counters.
