there may be tagged commands still running when we queue a request sense
command.
Solve this by using 2 DSA entry per LUN
- Now that we have the command DSA before select, we can load T/L/Q in
SCRATCHC. This makes the selection timeout handler simpler.
- Avoid a race condition when setting the free flag in the cmd ring (see
comment in the script)
- don't forget to update the ID in the head of LUN table after a sync/wide
negotiation. This fixes the command timeout at the first data command
after negotiation (the bus reset handler did update the ID properly,
so subsequent commands were OK).
- for DMA interrupts, clear fifo if it's not empty. Leaving the fifo dirty
would prevent subsequent interrupts from coming in.
- Various improvements in debug messages
- misc cleanups.
scheduler slot. This costs a few more instructions but divide the size of the
scheduler ring by 2, saving 1k of onboard RAM (a bus with 15 devices would
overflow the on-board RAM by 128 bytes).
- Add support for DT transfers (aka Ultra/160) in esiop
Note that DT transfers are not enabled for 53c1010-33 rev 0 yet; if I trust
FreeBSD it has a bug which prevent them to do DT properly.
From the same source there may be issues with some revs of 53c1010-66.
So check for version 3, not 4 when looking for DT support.
This should be safe as these bits are reserved for older devices, they
should be set to 0 when not supported.
taken from OpenBSD. Test hardware kindly provided by Intel. This still needs
management bits, and doesn't support older controllers, but that shouldn't
be hard to fix.
after the selection timeout is posted but the number executed isn't
reliable. So wait for MSG_OUT rigth after the select so that the state of
the script when the interruption is handled is known.
For this add another indirecton: the DSA in the LUN table points to
a table of DSA indexed by the tag number when tagged command is in use.
For non tagged command, the LUN DSA still points to the tables describing the
xfer directly.
yet.
If is restricted to SIOP which implement the load/store instruction, and
has 10 scratch registers (basically, 825 and newer, possibly 770).
It implements a different interface between host and script, using a real
ring for command starts, and improved support for reconnect which will allow
256 tag per device. It uses interrupt on the fly to signal complete command,
which allows several commands to be serviced per interrupt and doesn't require
the script to stop to signal command completion.
3 bits are lun address modifiers.
Remove code that (incorrectly) thought it was asking the f/w to only
PLOGI if not already PLOGI'd. The current f/w documentation tells us
that we have this backwards.
"true" at the appropriate times for non-PCMCIA interfaces. This
means that the ENETRESET path in cs_ioctl() now runs, thus fixing
multicast (and IPv6) on my Shark. Yay.
* Simplify cs_hash_index(): Rather than taking the bottom 6 bits of
a big-endian CRC32 and reversing them, just take the top 6 bits of
a little-endian CRC32.
So to disable them all better use 0xff instead of 0x00 as mask. Noted
by Matthias Drochner.
Move some initialization unrelated to interrupts back to its place at
attach time.
WI_RID_SCAN_APS in previous commit works for Intel Pro/Wirelss 2011
with firmware 2.51.1.
It seems that the firmware automatically updated after the card runs on
Windows 2000 with 2011_2011B_CD_3.0 in Intel web site.
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.
The card is Type 1 CF card and it doesn't have firmware in.
So we need to download the firmware image into the card before
touching it.
XXX downloading code should be written in generic (bus independent),
but I don't have enough information for now.
