2005-09-08[PATCH] USB: Code motion in the hub driverAlan Stern
This patch (as553) merely moves some code and deletes an unneeded test in the hub driver. This is in preparation for the patch that follows. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-09-08[PATCH] USB: Fix HP8200 detection in shuttle_usbatDaniel Drake
Adding flash-device support to the shuttle_usbat driver in 2.6.11 introduced the need to detect which type of device we are dealing with: CDRW drive, or flash media reader. The detection routine used turned out to not work for HP8200 CDRW users, who saw their devices being detected as a flash disk. This patch (which has been tested on both flash and cdrom) removes some unnecessary code, moves device detection to much later during initialization, and introduces a new detection routine which appears to work.

2005-09-08[PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern
29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."

2005-09-08[PATCH] USB Storage: wedge SCSI revision at 2 for usb-storage devicesMatthew Dharm
This patch started life as as479b, and has been rediffed. Please note the order of submission of this latest patch series -- even tho this has an older original number, it is the last patch I'll be sending today. This patch changes the reported SCSI revision level to 2 for all disk-type devices. This is needed in a few cases because the device reports a level of 3 or higher but then crashes when given a REPORT LUNS command (for which support is supposed to be mandatory at those levels). This shouldn't harm us, since it only matters for sparse LUNs and we have separate ways of coping with that.

This patch is originally from Nick Sillik, and has been rediffed against the latest tree. This patch adds usability to the OneTouch Button on Maxtor External USB Hard Drives. Using an unusual device entry it declares an extra init function which claims the interrupt endpoint associated with this button. The button is connected to the input system.

2005-09-08[PATCH] USB Storage: close a race condition in disconnect near queuecommandMatthew Dharm
This patch started life as as534, and has been re-diffed against the latest tree. usb-storage has a small loophole, a window between the time queuecommand accepts a new command and the time the control thread starts to execute it. If disconnect is called during that window, the driver won't cancel the pending command -- we've been relying on the SCSI core to cancel it for us during host removal. But it's better for usb-storage to cancel it; this avoids races and reduces reliance on the SCSI core. Fortunately cancelling these commands is easy to do; the key is to do it _before_ calling scsi_remove_host.

2005-09-08[PATCH] USB Storage: close a race condition in disconnect near probeMatthew Dharm
This patch started life as as533, and has been re-diffed against the current tree. Disconnect processing in usb-storage naturally divides into two parts: one to quiesce the driver (make sure no commands are executing or queued) and remove the host, and the other to deallocate all the USB and non-USB resources. This patch creates two subroutines to handle those two parts. Mostly it's just code movement, but there is one significant change. If the scsi-scanning thread fails to initialize but the host has successfully been added, we need to quiesce the driver before removing the host. After all, it's possible that scanning could have been initiated from somewhere else, such as userspace -- very low probability, but it's easily handled by calling the new subroutine.

2005-09-08[PATCH] USB Storage: remove dependency on SCSI-provided serial/tag numberMatthew Dharm
This patch started life as as531 from Alan Stern. It has been rediffed against the latest tree. The SCSI people have deprecated the use of scsi_cmnd.serial_number for anything other than printk. Worse than that, the SCSI core doesn't always increment the number (when the error handler is running, for example). So this patch creates a locally-stored value for use in bulk-only tags. The net result is a simplification, since we no longer have to save & restore the serial_number value while autosensing.

2005-09-08[PATCH] USB: ub 4: Zaitcev's quasi-S/GPete Zaitcev
Back out Axboe-style quasi-S/G and replace it with one command and repeated URBs. This is similar to what usb-storage does, only instead of a few URBs allocated together, one URB is reused. Jens's idea was very nice, but it collapsed when I had to support packet commads for CD burning. I cannot issue two or more packet commands where application expected only one. However, burning does not work completely yet. The cdrecord starts, recognizes the device, then aborts without writing a TOC.

This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and implemented that night before 4 a.m. Surprisingly, it worked right away... Alas, I had to skip some OLS partying, but it was for the good cause. Now the speed of ub is quite acceptable even on partitions with small block size. The ub does not really support S/G. Instead, it just tells the block layer that it does. Then, most of the time, the block layer merges requests and passes single-segmnent requests down to ub; everything works as before. Very rarely ub gets an unmerged S/G request. In such case, it issues several commands to the device. I added a small array of counters to monitor the merging (sg_stat). This may be dropped later.

2005-09-08[PATCH] USB: Prevent hid-core claiming Apple Bluetooth device on new G4 ↵Andrew de Quincey
powerbooks To recap: My new G4 powerbook has a bluetooth device that boots up in what apppears to be a compatability mode - it looks exactly like an HID keyboard/mouse device. A special command sequence is sent to switch it into full bluetooth mode. When this occurs the original HID device vanishes, and a new (bluetooth HID) USB device appears on the bus with a different product ID. The original thread is here: http://sourceforge.net/mailarchive/message.php?msg_id=12532263 The attached patch adds the device to the hid-core quirks so that hid-core ignores it.

2005-09-08[ARM] 2892/1: remove gcc workaround for direct access to absolute memory ↵Nicolas Pitre
addresses Patch from Nicolas Pitre It used to make a difference in the gcc-2.95 era. However these days modern gcc apparently got better at not being influenced by such constructs (which is good in general) and therefore such workaround is of no real advantage anymore. The good news is that gcc (from version 4.1.0) is now fixed with regards to the defficiency this workaround was trying to address. For those interested the patch can easily be backported to older gcc versions and can be found here: http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/arm/arm.c.diff?r1=1.476&r2=1.478 and also here: http://savannah.gnu.org/cgi-bin/viewcvs/gcc/gcc/gcc/config/arm/arm.c.diff?r1=text&tr1=1.476&r2=text&tr2=1.478&diff_format=u Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-09-08[PATCH] PCI: Add pci_walk_bus function to PCI core (nonrecursive)Paul Mackerras
The PCI error recovery infrastructure needs to be able to contact all the drivers affected by a PCI error event, which may mean traversing all the devices under a given PCI-PCI bridge. This patch adds a function to the PCI core that traverses all the PCI devices on a PCI bus and under any PCI-PCI bridges on that bus (and so on), calling a given function for each device. This provides a way for the error recovery code to iterate through all devices that are affected by an error event. This version is not implemented as a recursive function. Instead, when we reach a PCI-PCI bridge, we set the pointers to start doing the devices on the bus under the bridge, and when we reach the end of a bus's devices, we use the bus->self pointer to go back up to the next higher bus and continue doing its devices.
