* [PATCH] USB: Let usbmon collect less garbagePete Zaitcev2006-01-041-13/+6
| | | | | | | | | | Alan Stern pointed out that (in 2.6 kernel) one successful submission results in one callback, even for ISO-out transfers. Thus, the silly check can be removed from usbmon. This reduces the amount of garbage printed in case of ISO and Interrupt transfers. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | This patch (as616) changed the uhci_explen macro in uhci-hcd.h so that it now accepts the desired length, rather than length - 1 with special handling for 0. This also fixes a minor bug that would show up only when a driver submits a 0-length bulk URB. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] USB: Don't assume root-hub resume succeedsAlan Stern2006-01-041-0/+2
| | | | | | | | | | | | | | This patch (as614) makes a small change to the part of the hub driver responsible for remote wakeup of root hubs. When these wakeups occur the driver is suspended, and in case the resume fails the driver should remain suspended -- it shouldn't try to proceed with its normal processing. This will hardly ever matter in normal use, but it did crop up while I was debugging a different problem.

* [PATCH] USB: usbserial: race-condition fix.Luiz Fernando Capitulino2006-01-042-1/+17
| | | | | | | | | | | | | | | | | | | There is a race-condition in usb-serial driver that can be triggered if a processes does 'port->tty->driver_data = NULL' in serial_close() while other processes is in kernel-space about to call serial_ioctl() on the same port. This happens because a process can open the device while there is another one closing it. The patch below fixes that by adding a semaphore to ensure that no process will open the device while another process is closing it. Note that we can't use spinlocks here, since serial_open() and serial_close() can sleep.

* [PATCH] USB: Consider power budget when choosing configurationAlan Stern2006-01-045-81/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as609) changes the way we keep track of power budgeting for USB hubs and devices, and it updates the choose_configuration routine to take this information into account. (This is something we should have been doing all along.) A new field in struct usb_device holds the amount of bus current available from the upstream port, and the usb_hub structure keeps track of the current available for each downstream port. Two new rules for configuration selection are added: Don't select a self-powered configuration when only bus power is available. Don't select a configuration requiring more bus power than is available. However the first rule is #if-ed out, because I found that the internal hub in my HP USB keyboard claims that its only configuration is self-powered. The rule would prevent the configuration from being chosen, leaving the hub & keyboard unconfigured. Since similar descriptor errors may turn out to be fairly common, it seemed wise not to include a rule that would break automatic configuration unnecessarily for such devices. The second rule may also trigger unnecessarily, although this should be less common. More likely it will annoy people by sometimes failing to accept configurations that should never have been chosen in the first place. The patch also changes usbcore's reaction when no configuration is suitable. Instead of raising an error and rejecting the device, now the core will simply leave the device unconfigured. People can always work around such problems by installing configurations manually through sysfs.

| | | | | | | | | | | The earlier USB locking updates didn't touch the suspend/resume routines. They need updating as well, since now the caller holds the device semaphore.

* [PATCH] USB: Disconnect children during hub unbindAlan Stern2006-01-041-63/+31
| | | | | | | | | | | | | | | | | This patch (as606b) is an updated version of my earlier patch to disconnect children from a hub device when the hub driver is unbound. Thanks to the changes in the driver core locking, we now know that the entire hub device (and not just the interface) is locked whenever the hub driver's disconnect method runs. Hence it is safe to disconnect the child device structures immediately instead of deferring the job. The earlier version of the patch neglected to disable the hub's ports. We don't want to forget that; otherwise we'd end up with live devices using addresses that have been recycled. This update adds the necessary code.

* [PATCH] USB: Remove USB private semaphoreAlan Stern2006-01-049-154/+37
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as605) removes the private udev->serialize semaphore, relying instead on the locking provided by the embedded struct device's semaphore. The changes are confined to the core, except that the usb_trylock_device routine now uses the return convention of down_trylock rather than down_read_trylock (they return opposite values for no good reason). A couple of other associated changes are included as well: Now that we aren't concerned about HCDs that avoid using the hcd glue layer, usb_disconnect no longer needs to acquire the usb_bus_lock -- that can be done by usb_remove_hcd where it belongs. Devices aren't locked over the same scope of code in usb_new_device and hub_port_connect_change as they used to be. This shouldn't cause any trouble. Along with the preceding driver core patch, this needs a lot of testing. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] USB: allow usb drivers to disable dynamic idsGreg Kroah-Hartman2006-01-0432-0/+52
| | | | | | | | | | | This lets drivers, like the usb-serial ones, disable the ability to add ids from sysfs. The usb-serial drivers are "odd" in that they are really usb-serial bus drivers, not usb bus drivers, so the dynamic id logic will have to go into the usb-serial bus core for those drivers to get that ability.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A driver for USB ADSL modems based on the ADI eagle chipset using the usb_atm infrastructure. The managing part was taken from bsd ueagle driver, other parts were written from scratch. The driver uses the in-kernel firmware loader : - to load a first usb firmware when the modem is in pre-firmware state - to load the dsp firmware that are swapped in host memory. - to load CMV (configuration and management variables) when the modem boot. (We can't use options or sysfs for this as there many possible values. See https://mail.gna.org/public/eagleusb-dev/2005-04/msg00031.html for a description of some) - to load fpga code for 930 chipset. The device had 4 endpoints : * 2 for data (use by usbatm). The incoming endpoint could be iso or bulk. The modem seems buggy and produce lot's of atm errors when using it in bulk mode for speed > 3Mbps, so iso endpoint is need for speed > 3Mbps. At the moment iso endpoint need a patched usbatm library and for this reason is not included in this patch. * One bulk endpoint for uploading dsp firmware * One irq endpoint that notices the driver - if we need to upload a page of the dsp firmware - an ack for read or write CMV and the value (for the read case). If order to make the driver cleaner, we design synchronous (read|write)_cmv : -send a synchronous control message to the modem -wait for an ack or a timeout -return the value if needed. In order to run these synchronous usb messages we need a kernel thread. The driver has been tested with sagem fast 800 modems with different eagle chipset revision and with ADI 930 since April 2005.

* [PATCH] USB: EHCI: fix conflation of buf == 0 with len == 0Alan Stern2006-01-041-7/+7
| | | | | | | | | | | | | | | | | When the ehci-hcd driver prepares a control URB, it tests for a zero-length data stage by looking at the transfer_dma value instead of the transfer_buffer_length. (In fact it does this even for non-control URBs, which is an additional aspect of the same bug.) However, under certain circumstances it's possible for transfer_dma to be 0 while transfer_buffer_length is non-zero. This can happen when a freshly allocated page (mapped to address 0 and marked Copy-On-Write, but never written to) is used as the source buffer for an OUT transfer.

* [PATCH] USB: isp116x-hcd: cleanupOlav Kongas2006-01-043-288/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch makes a cleanup of isp116x-hcd. Most of the volume of the patch comes from 2 sources: moving the code around to get rid of a few function prototypes and reworking register dumping functions/macros. Among other things, switched over from using procfs to debugfs. Cleanup. The following changes were made: - Rework register dumping code so it can be used for dumping to both syslog and debugfs. - Switch from procfs to debugfs.. - Die gracefully on Unrecoverable Error interrupt. - Fix memory leak in isp116x_urb_enqueue(), if HC happens to die in a narrow time window. - Fix a 'sparce' warning (unnecessary cast). - Report Devices Removable for root hub ports by default (was Devices Permanently Attached). - Move bus suspend/resume functions down in code to get rid of a few function prototypes. - A number of one-line cleanups. - Add an entry to MAINTAINERS.

* [PATCH] USB: isp116x-hcd: support reiniting HC on resumeOlav Kongas2006-01-041-8/+18
| | | | | | | | | | | | | | | | Until now the isp116x-hcd had no support to reinitialize the HC on resume, if the controller lost its state during suspend. This patch, generated against your Oct 26 git tree, adds that support. The patch is basically the same as the one tested by Ivan Kalatchev, who reported the problem, on 2.6.13. Please apply, Support reinitializing the isp116x host controller from scratch on resume, if the controller has lost its state.
