be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
accept ranges as well as single addresses. Still need to go through any key
areas and remove the malloc's and replace these with some sort of pooling
instead.
support up to the max ohci descriptor segments. Then attempt to fill it in
via a load. Use the number of segments filled in as the basis for figuring
out how many descriptors to supply to the ohci DMA engine.
XXX: Still needs to account for requests which because of splits may overflow
the 6 dma descriptors available today. For now this fixes cases where a
single 512 byte write was getting split into 2 dma segments from 1 incoming
iov request
isochronous reception routine for IEEE 1394 OHCI (fwohci). The
transmission part is under construction.
The minimum configuration options for this feature are:
# IEEE 1394 (i.LINK)
fwohci* at pci? dev ? function ?
pseudo-device fwiso 1
Also, add unit location fields to the ROM image. The p1212 spec requires
unit locations if you have 2 or more unit directories which is the case for
ipv4 and ipv6 compiled into a kernel.
been tested on i386. It does not have any interface for useland to
get isochoronous stream. The isochoronous acquisition interface
should be determined.
- fwohci_arrq_input: Do not return if next packet is in the buffer,
or the next packet cannot be received until the next receive interrupt.
- fwohci_uid_collect: XXX change M_WAITOK to M_NOWAIT for now, since there is
no lock but only one instance must be allowed here.
split fwohci_uid_req() and retry to get uid.
XXX need timer to wait some moment between retries...
- Add DELAY(10) for wait loop.
- split fwohci_buf_stop() into _stop_tx() and _stop_rx() because receiver
should not be stopped at bus-reset.
- split fwohci_buf_input() into _input() and _input_ppb() to improve
performance slightly.
Clean up one bug in a DPRINTF in arrs_input which could panic on some packets.
Gut the ack/response functionality and clean it up so all packets get checked
correctly and the abuf struct isn't used once the ab_cb has happened (there
still could be ack packets waiting to be processed at that time).
Finally, add some documentation explaining read/write/inreg and their
purpose/argument calling.
