may retry it as a memory read multiple command under some circumstances.
This can totally confuse some PCI controllers, so ensure that it
will never do this by making sure that the Read Threshold (FIFO
Read Request Control) field of the FIFO Valid Byte Count and Control
registers for both channels (BA5 offset 0x40 and 0x44) are set to
be at least as large as the cacheline size register (the unit of
measure for these registers is 32 bytes).
atw seems to work better now that it gets this right: for one thing,
the RSSI can be seen to change as I walk around the office with my
laptop.
Thanks to Todd C. Miller for pointing out my mistake.
Attempting to read a maximum-size string descriptor causes my kue device to go
completely apeshit. So, go back to the original method, but allow the device
to return a shorter string than it claimed.
than losing, do what Windows does: just request the maximum size, and allow a
shorter response. Obsoletes the need for UQ_NO_STRINGS, and therefore these
"quirks" are removed.
just have to take an interrupt for each sector.
Tested with one laptop disk (which normally runs in DMA mode and was forced
to single-sector transfers) and 3 CF cards. Increases the performance of
the CF cards substantially (760KB/s->1240KB/s in one case, 410KB/s->750KB/s
in the other two cases).
point to directories which do not exist (and are not wanted) in our source tree.
While we're here, was `libexec/spamd' approved for import? It conflicts with the
name of a tool in pkgsrc which a _lot_ of developers and users of NetBSD are using...
If the input to 'disklabel' (non -i) referenced a partition two or more
larger than that permitted by npartitions it would error out with 'bad
partition name' (and the option given to re-edit if -e). If a partition one
larger was used it would be dropped from the disklabel with a warning and the
label written anyway! The (off by one) check for a bad partition name was
against npartitions anyway, rather than MAXPARTITIONS. npartitions was just
read from the disklabel and could have been set to an arbitrary value.
Given 'disklabel -i' sets npartitions automatically, make the normal case
check partition names against MAXPARTITIONS, and if necessary increase
npartitions to the size needed to hold the last partition used.
While here remove two 'write only' uses of a 'part' variable.
