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.
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
as tsutsui@ suggested, and include <sys/param.h> in sha2.c instead.
On the vax, this causes <machine/macros.h> to be included, and it contains
that machine's memset() macro+inline.
- Support detachment. From KIYOHARA Takashi.
- Add PCI detachment functionality (albeit not very interesting when
the bus can not yet be rescanned).
- Rework interrupt handlers to reduce near-duplicate code.
Borrowed from ahcisata(4).
- Attempt to make polled I/O work. Untested.
- Fix formatting of some messages.
- For always-polled commands, disable interrupt
at slot level rather than port level.
- Instead of busy-waiting indefinitely for completion of some commands
move on after 31 seconds. Use cv_timedwait(9) instead of DELAY(9).
- Use abstracted SATA FIS code.
- Enable use of disks that don't respond with the standard signature.
Call rtc_set_ymdhms() from xen/xen/clock.c:xen_rtc_set() for xen3 dom0
kernels as the Xen3 hypervisor doesn't write the new date/time to the CMOS
by itself.
Now a XEN3_DOM0 kernel properly updates the CMOS time.
