* USB: add ep->enableAlan Stern2007-10-126-16/+17
| | | | | | | | | | | | | | | | | | This patch (as944) adds an explicit "enabled" field to the usb_host_endpoint structure and uses it in place of the current mechanism. This is merely a time-space tradeoff; it makes checking whether URBs may be submitted to an endpoint simpler. The existing mechanism is efficient when converting urb->pipe to an endpoint pointer, but it's not so efficient when urb->ep is used instead. As a side effect, the procedure for enabling an endpoint is now a little more complicated. The ad-hoc inline code in usb.c and hub.c for enabling ep0 is now replaced with calls to usb_enable_endpoint, which is no longer static.

* USB: add urb->epAlan Stern2007-10-123-39/+65
| | | | | | | | | | | | | | | | | | | This patch (as943) prepares the way for eliminating urb->pipe by introducing an endpoint pointer into struct urb. For now urb->ep is set by usb_submit_urb() from the pipe value; eventually drivers will set it themselves and we will remove urb->pipe completely. The patch also adds new inline routines to retrieve an endpoint descriptor's number and transfer type, essentially as replacements for usb_pipeendpoint and usb_pipetype. usb_submit_urb(), usb_hcd_submit_urb(), and usb_hcd_unlink_urb() are converted to use the new field and new routines. Other parts of usbcore will be converted in later patches. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: OHCI handles more ZFMicro quirksMike Nuss2007-10-125-75/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ZF Micro OHCI controller exhibits unexpected behavior that seems to be related to high load. Under certain conditions, the controller will complete a TD, remove it from the endpoint's queue, and fail to add it to the donelist. This causes the endpoint to appear to stop responding. Worse, if the device is removed while in that state, OHCI will hang while waiting for the orphaned TD to complete. The situation is not recoverable without rebooting. This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag: 1. A watchdog routine periodically scans the OHCI structures to check for orphaned TDs. In these cases the TD is taken back from the controller and completed normally. 2. If a device is removed while the endpoint is hung but before the watchdog catches the situation, any outstanding TDs are taken back from the controller in the 'sanitize' phase. The ohci-hcd driver used to print "INTR_SF lossage" in this situation; this changes it to the universally accurate "ED unlink timeout". Other instances of this message presumably have different root causes. Both this Compaq quirk and a NEC quirk are now properly compiled out for non-PCI builds of this driver.

* usblp: Implement the ENOSPC conventionPete Zaitcev2007-10-121-26/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a mode when a printer returns ENOSPC when it runs out of paper. The default remains the same as before. An application which wishes to use this function has to enable it explicitly with an ioctl LPABORT. This is done on a request by our (Fedora) CUPS guy, Tim Waugh. The API is similar enough to the lp0's one that CUPS works with both (but see below), but it's has some differences. Most importantly, the abort mode is persistent in case of lp0: once tunelp was run your cat fill blow up until you reboot or run tunelp again. For usblp, I made it so the abort mode is only in effect as long as device is open. This way you can mix and match CUPS and cat(1) freely and nothing bad happens even if you run out of paper. It is also safer in the face of any unexpected crashes. It has to be noted that mixing LPABORT and O_NONBLOCK is not advised. It probably does not do what you want: instead of returning -ENOSPC it will always return -EAGAIN (because it would otherwise block while waiting for the paper). Applications which use O_NONBLOCK should continue to use LPGETSTATUS like before. Finally, CUPS actually requires patching to take full advantage of this. It has several components; those which invoke LPABORT work, but some of them need the ioctl added. This is completely compatible, you can mix old CUPS and new kernels or vice versa.

| * [POWERPC] Add legacy serial support for OPB with flattened device treeValentine Barshak2007-10-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-1223-258/+513
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here.
