* [PATCH] bitops: hweight() related cleanupAkinobu Mita2006-03-261-2/+1
| | | | | | | | | | | | | By defining generic hweight*() routines - hweight64() will be defined on all architectures - hweight_long() will use architecture optimized hweight32() or hweight64() I found two possible cleanups by these reasons.

* sbp2: update 36byte inquiry workaround (fix compatibility regression)Stefan Richter2006-02-231-23/+19
| | | | | | | | | | | | | Since about Linux 2.6.14, sbp2's inquiry workaround did not work anymore due to changes in the SCSI layer. Update it to become effective again. Testing one of the two known affected bridges has shown that skip_ms_page_8 is required as well. Also, make force_inquiry_hack tunable via /sys/module/sbp2/parameters.

* sbp2: variable status FIFO address (fix login timeout)Stefan Richter2006-02-232-69/+59
| | | | | | | | | | | | | | | | | | | | | | | | Let the ieee1394 core select a suitable 1394 address range for sbp2's status FIFO instead of using a fixed range. Since the core only selects addresses which are guaranteed to be out of the "physical range" as per OHCI 1.1, this patch also fixes an old bug: OHCI controllers which implement a writeable PhysicalUpperBound register included sbp2's status FIFO in the physical range. That way sbp2 was never notified of a succesful login and always failed after timeout. Affected OHCI host adapters include ALi and Fujitsu controllers. As another side effect of this patch, the status FIFO is no longer located in a range for which OHCI chips perform "posted writes". Each status write now requires a response subaction. But since large data transfers involve only few status writes, there is no measurable decrease of I/O throughput. What's more, the status FIFO is now safe from potential host bus errors. Nevertheless, posted writes could be re-enabled by extensions to the ARM features of the 1394 stack.

* sbp2: fix another deadlock after disconnectionStefan Richter2006-02-231-2/+8
| | | | | | | | | | | | If there were commands enqueued but not completed before an SBP-2 unit was unplugged (or an attempt to reconnect failed), knodemgrd or any process which tried to remove the device would sleep uninterruptibly in blk_execute_rq(). Therefore make sure that all commands are completed when sbp2 retreats.

* [PATCH] don't mangle INQUIRY if cmddt or evpd bits are setAl Viro2006-02-181-9/+1
| | | | | | | | | sbp2.c mangles INQUIRY response in a way that only applies to standard inquiry data (i.e. when both cmddt and evpd bits are 0). Leave other cases alone; e.g. when asking for VPD the length of reply is in byte 3, not 4 and byte 4 is the first byte of device serial number. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* | ieee1394: run high-level updates before high-level probesStefan Richter2005-12-121-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a bus reset, let nodemgr call high-level update hooks first for nodes which do not need to be probed. The main benefit is for a bus with more than one SBP-2 device: SBP-2 reconnects will be performed before SBP-2 logins, thus have a much higher chance to succeed, and their SCSI devices will not be blocked much longer than necessary. This was demonstrated for Linux 2.4 by Dave Cinege a while ago. A better approach would be to perform time-consuming probes in parallel by a subthread. I actually plan to implement this for sbp2 but it may take a while to get that done and tested. Until then, this tweak is a huge improvement for users with multiple SBP-2 devices.
