* [PATCH] sbp2: fix check of return value of ↵Stefan Richter2006-06-051-1/+1
| | | | | | | | | | | | | | | | | | hpsb_allocate_and_register_addrspace() From: Stefan Richter <stefanr@s5r6.in-berlin.de> I added a failure check in patch "sbp2: variable status FIFO address (fix login timeout)" --- alas for a wrong error value. This is a bug since Linux 2.6.16. Leads to NULL pointer dereference if the call failed, and bogus failure handling if call succeeded.

Besides bringing back a very minor bandwidth tweak from Linux 2.6.15.x and older, this also fixes an interoperability regression since 2.6.16: http://bugzilla.kernel.org/show_bug.cgi?id=6356 (sbp2: scsi_add_device failed.

* [PATCH] sbp2: add read_capacity workaround for iPodStefan Richter2006-05-172-4/+46
| | | | | | | | | | | | | | | | | | | | Apple decided to copy some USB stupidity over to FireWire. The sector number returned by iPods from read_capacity is one too many. This may cause I/O errors, especially if the kernel is configured for EFI partition support. We use the same workaround as usb-storage but have to check for different model IDs. http://marc.theaimsgroup.com/?t=114233262300001 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187409 Acknowledgements: Diagnosis and therapy by Mathieu Chouquet-Stringer <ml2news@free.fr>, additional data about affected and unaffected Apple hardware from Vladimir Kotal, Sander De Graaf, Bryan Olmstead and Hugh Dixon.

* [PATCH] sbp2: consolidate workaroundsStefan Richter2006-05-172-71/+97
| | | | | | | | | | | | | | | | | | Grand unification of the three types of workarounds we have so far. The "skip mode page 8" workaround is now limited to devices which pretend to be of TYPE_DISK instead of TYPE_RBC. This workaround is no longer enabled for Initio bridges. Patch update in anticipation of more workarounds: - Add module parameter "workarounds". - Deprecate parameter "force_inquiry_hack". - Compose the blacklist of a compound type for better readability and extensibility. - Remove a now unused #define.

* [PATCH] sbp2: fix spinlock recursionStefan Richter2006-04-021-17/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sbp2util_mark_command_completed takes a lock which was already taken by sbp2scsi_complete_all_commands. This is a regression in Linux 2.6.15. Reported by Kristian Harms at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187394 [ More complete commentary, as response to questions by Andrew: ] > This changes the call environment for all implementations of > ->Current_done(). Are they all safe to call under this lock? Short answer: Yes, trust me. ;-) Long answer: The done() callbacks are passed on to sbp2 from the SCSI stack along with each SCSI command via the queuecommand hook. The done() callback is safe to call in atomic context. So does Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI low-level handlers rely on this fact. So whatever this callback does, it is "self-contained" and it won't conflict with sbp2's internal ORB list handling. In particular, it won't race with the sbp2_command_orb_lock. Moreover, sbp2 already calls the done() handler with sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands(). I admit this is ultimately no proof of correctness, especially since this portion of code introduced the spinlock recursion in the first place and we didn't realize it since this code's submission before 2.6.15 until now. (I have learned a lesson from this.) I stress-tested my patch on x86 uniprocessor with a preemptible SMP kernel (alas I have no SMP machine yet) and made sure that all code paths which involve the sbp2_command_orb_lock were gone through multiple times.

| * [PATCH] powerpc: Kill _machine and hard-coded platform numbersBenjamin Herrenschmidt2006-03-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | sbp2: prevent unloading of 1394 low-level driverStefan Richter2006-03-281-0/+9
|/ | | | | | | | | | | | | | 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.

* 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.

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.

The write request is now directed to specific nodes instead of being broadcast to all nodes at once, and it is only performed if a previous read request at this register succeeded. Fixes an old interoperability problem which was perceived as a 2.6.14-specific regression: http://marc.theaimsgroup.com/?t=113190586800003 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jody McIntyre <scjody@modernduck.com>

* | ieee1394: resume remote ports when starting a host (fixes device recognition)Stefan Richter2005-12-012-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | After initializing an IEEE 1394 host, broadcast a resume packet. This makes remote nodes visible which suspended their ports while the host was down. Such nodes had to be unplugged and replugged in order to be recognized. Motorola DCT6200 cable reciever was affected, probably other devices too. http://marc.theaimsgroup.com/?t=113202715800001 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jody McIntyre <scjody@modernduck.com>
