* USB: remove PICDEM FS USB demo (04d8:000c) device from ldusbXiaofan Chen2008-05-14
| | | | | | | | | | | | | | | | | Microchip has changed the PICDEM FS USB demo device (0x04d8:000c) to use bulk transfer and not interrupt transfer. So I've updated the libusb based program here (Post #31). http://forum.microchip.com/tm.aspx?m=106426&mpage=2 So I believe that the in-kernel ldusb driver will no longer work with the demo firmware. It should be removed. Signed-off-by: Xiaofan Chen <xiaofanc@gmail.com> Cc: Michael Hund <MHund@LD-Didactic.de> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: unusual_devs: Add support for GI 0401 SD-Card interfaceFilip Aben2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enables the SD-Card interface on the GI 0401 HSUPA card from Option. The unusual_devs.h entry is necessary because the device descriptor is vendor-specific. That prevents usb-storage from binding to it as an interface driver. This revised patch adds a small comment explaining why and reduces the rev range. T: Bus=02 Lev=01 Prnt=01 Port=06 Cnt=01 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.)

* USB: serial gadget: descriptor cleanupDavid Brownell2008-05-14
| | | | | | | | | | | | | | | | | | | Bugfix some serial gadget descriptors: - Stop mangling the low bits (controller type ID) of bcdDevice; just use the high bits for a driver revision code. - Serial numbers that aren't specific to individual devices are useless; stop reporting "0" for this. - Since it's not part of a CDC-conformant function, the "bulk only" configuration shouldn't be using "CDC Data" as its interface class. Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).

| | | | | | | | | | | | | | | This removes a needless data structure from the serial gadget code; it's a small code shrink, and a larger data shrink. Since "struct usb_request" already has a "struct list_head" reserved for use by gadget drivers, the serial gadget code doesn't need to allocate wrapper structs to hold that list ... it can (and should!) just use the list_head provided for that exact use.

| | | | | | | | | | | | | | | | | This patch (as1087d) fixes a long-standing problem in usbcore: Device, interface, and endpoint attributes aren't added until _after_ the creation uevent has already been broadcast. Unfortunately there are a few attributes which cannot be created that early. The "descriptors" attribute is binary and so must be created separately. The power-management attributes can't be created until the dev/power/ group exists. And the interface string can vary from one altsetting to another, so it has to be created dynamically.

But mailbox register 0 has the status code for the mailbox command (in this case, Set Target Parameters). Potential values are: /* * ISP mailbox command complete status codes */ So clearly that is in error. I can't think what the author of that line was looking for in a mailbox register, so I just eliminated the AND. flag is used later in the function, and I think that the later usage was also wrong, though it was used to set values that aren't used. Oh well, an overhaul of this driver is not what I want to do now -- just a bugfix. After the fix, I found that my disks were getting a queue depth of 255, which is far too many. Most SCSI disks are limited to 32 or 64. In any case, there's no point, queueing up a bunch of commands to the adapter that will just result in queue full or starve other targets from being issued commands due to running out of internal memory. So I dropped default queue depth to 32 (from which 1 is subtracted elsewhere, giving net of 31). I tested with a Seagate ST336753LC, and results look good, so I'm satisfied with this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the ping tmo is longer than the recv tmo then we could miss a window where we were supposed to check the recv tmo. This happens because the ping code will set the next timeout for the ping timeout, and if the ping executes quickly there will be a long chunk of time before the timer wakes up again. This patch has the ping processing code kick off a recv tmo check when getting a nop in response to our ping.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch fixes a bug in the iscsi nop processing. The target sends iscsi nops to ping the initiator and the initiator has to send nops to reply and can send nops to ping the target. In 2.6.25 we moved the nop processing to the kernel to handle problems when the userspace daemon is not up, but the target is pinging us, and to handle when scsi commands timeout, but the transport may be the cause (we can send a nop to check the transport). When we added this code we added a bug where if the transport timer wakes at the exact same time we are supposed to check for a nop timeout we drop the session instead of checking the transport. This patch checks if a iscsi ping is outstanding and if the ping has timed out, to determine if we need to signal a connection problem.

| * [SCSI] gdth: fix timer handlingJames Bottomley2008-05-08
| | | | | | | | | | | | | | | | | | | | | | The global timer handling is problematic in that if someone unbinds a PCI gdth instance, the BUG_ON() in the timer will cause a panic. Fix this by making the timer start and stop depending on whether there are instances present. This should also permit binding and unbinding to work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some versions of X used the mprotect workaround to change caching type from UC to WB, so that it can then use mtrr to program WC for that region [1]. Change the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS. With this change, X will not need to use mprotect workaround to get WC type since the MTRR mapping type will be honored. The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So, this X workaround will stop working as well.

Or all of ALSA ISA DMA at least. All > ISA soundcards are silent following that commit -- no error > messages, everything appears fine, just silence. That patch is buggy. We had an implicit assumption that dev = NULL for ISA devices that require 24bit DMA. The recent work on x86 dma_alloc_coherent() breaks the ISA DMA buffer allocation, which is represented by "dev = NULL" and requires 24bit DMA implicitly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix uninitialized variable in __pci_osc_support_set(). If the ACPI namespace doesn't have any device object corresponding to the specified hid, 'retval' in __pci_osc_support_set() is not changed by the acpi_query_osc() callback. Since 'retval' is not initizlized in the current implementation, the contents of 'retval' is undefined in this case. This causes a mis-handling of ctrlset_buf[OSC_SUPPORT_TYPE] and will cause an unexpected result in the subsequent pci_osc_control_set() call as a result.
