2006-03-28sbp2: check for ARM failureStefan Richter
Sbp2 did not check for successful registration of the lower address range when CONFIG_IEEE1394_SBP2_PHYS_DMA was set. If hpsb_register_addrspace failed, a "login timed-out" would occur which is misleading. Now sbp2 logs a sensible error message.

2006-03-28sbp2: prevent unloading of 1394 low-level driverStefan Richter
When a new SBP-2 unit is added, sbp2 now takes a reference on the 1394 low-level driver (ohci1394 or pcilynx). This prevents the 1394 host driver module from being unloaded, e.g. by an administrative routine cleanup of unused kernel modules or when another 1394 driver which depends on ohci1394 is unloaded. The reference is dropped when the SBP-2 unit was disconnected, when sbp2 is unloaded or detached from the unit, or when addition of the SBP-2 unit failed.

2006-03-28[PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt
This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.

2006-02-23sbp2: update 36byte inquiry workaround (fix compatibility regression)Stefan Richter
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.

2006-02-23sbp2: variable status FIFO address (fix login timeout)Stefan Richter
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.

2006-02-23sbp2: fix another deadlock after disconnectionStefan Richter
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.

2005-12-12ieee1394: run high-level updates before high-level probesStefan Richter
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.
