Using pdc202xx_setup_channel() for PDC20268 and newer is wrong, and will
cause trap trying to read from a non-existent register on some arches
(e.g. macppc).
pointed out by Makoto Fujiwara on port-macppc.
would be overwritten, so allocate memory for a full packet via malloc()
instead. Use correct buffer maxlen (must be 2 complemet). Bug reported
and helped to find by Roar Thronæs.
-cut yhe trailing '\r' from input lines so that commands are recognized
-use db_vprintf() for output in interactive mode to get the "|more" effect
-do the same setjmp() game as ddb, so we can return to the prompt
Reenable statistics interrupts, reading it as 16bit caused it to not be cleared,and thus the eventual interrupt to not be cleared (and this caused an
infinite loop in interrupt routine).
While I'm there count STE_CarrierSenseErrors as oerror (this is incremented
each time we try to send a packet and the link is down).
- when a transmit underrun occurs, only reset the transmit logic. This prevents
the link from going down at the MII level (the same logic can probably
be used for other transmit errors)
- set the urgent threshold to half the start threshold. From experiments
this helps a bit decreasing the number of underruns
Now that underruns don't cause the interface to stop for several seconds,
make back out the default transmit threshold to 128.
XS_SELTIMEOUT and XS_TIMEOUT errors- but only do so if the device exists
already.
Devices that are being probed won't be found via periph_lookup, so we can
use that to find if a device exists for the purposes of honoring retries.
among other things, it behaved as if full-duplex audio devices
were always ready for writing. Also commented the code in case.
This fixes PRs kern/11179 and kern/13829.
XXX: this program currently doesn't parse macros that cross the EOL with \
(there are a couple in sys/dev/scsipi/scsi_message.h).
with that issue temporarily worked around, this change generates the
same output as the version of aicasm without this change.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
