1) It's not documented anywhere.
2) The problem it's attempting to warn about is not documented anywhere.
3) There are no example configs (or any I found with Google) that use the
"listen" directive.
4) In any event, it's poorly worded and unclear what it's talking about.
The controller is handling them, calling scsipi_done() here will end up in the
xfer being scsipi_done()'ed a second time when it completes in the controller
code. In addition, the way the loop was done here would end up in an infinite
loop, because the channel kernel thread needs to run to remove a command from
this queue.
scsibusdetach(): scsipi_done() all commands from periph_xferq. The controller
is already gone, and these commands will never complete.
Shut down the channel (which will cause the kenrel thread to exit) after
detaching the childs, as they will need the kernel thread for
scsipi_wait_drain().
Fix kernel hang or deadlock when detaching devices (either by scsictl detach
or unplug) with active commands.
on transmit.
- On 82544 and up, allocate 4096 Tx descriptors rather than just 256.
82543 and down must still use 256, due to errata.
- Allow up to 256 DMA segments per packet. I have observed some truly
pathological mbuf chains under certain (admittedly uncommon) workloads
when jumbo frames are in use.
around the delimiters (commas and colons). Also, at the end of
the "RESPONSE TYPES" section for "USERID" it is explicitly noted
that any spaces after the colon following the OSTYPE field *are*
part of the identifier.
lose when booted from pxeboot.
. make sure that i386_alldisks gets initialized even if
bios geometry information is not available in the bootinfo
. if i386_alldisks is not initialized, have sysctl return EOPNOTSUPP
. compile pxeboot with -DPASS_BIOSGEOM and I386_INCLUDE_DISK=yes
this may increase the size of pxeboot which is required to run
in 64k. However, it seems to be working ok on my system
"dereferencing type-punned pointer will break strict-aliasing rules"
which occurs when compiling crypto_openssl.c with -O[23s].
This should be gone once a new release of kame with a fix applied
is imported.
