sdattach(). This allows DIOCGDISKINFO to do the right thing even when
the media has changed. Note that drvctl -p will only DTRT if disk has
been opened since the most recent media chenged.
for device mmap()'s, if the D_NEGOFFSAFE flag is set, do not check
if the offset is negative.
this should go away with the test itself when all drivers are audited
and checked to not fail with negative offsets.
Don't check gainst the last ack received, but the expected sequence number.
This makes RST handling independent of delayed ACK. From Joanne M Mikkelson.
Conditionally compiled in when MODULAR_KERNEL is defined in the Makefile
(or during the build process).
Use kmod functions to see if the puffs module is loaded in the kernel,
and to load it if it is not already loaded.
(Used to work because the redefinition was identical to the original
definition, but no longer.)
While I'm here, define sizeofA() in terms of __arraycount() from
<sys/cdefs.h>.
with our changes and the work recently done by Arto Huusko
<arto.huusko@pp2.inet.fi> and FUKAUMI Naoki <fun@naobsd.org>.
it includes all the changes arto provided from both mesa-drm and
the r6xx-r7xx-support branch. it does not yet include code to
handle the (deleted) drm_pciids.h file, but i'll probably just
check in a generated one for now.
i have not yet merged the changes from outside this dir.
from arto's messages to tech-x11:
The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.
Other changes:
- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers
- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared
