This reverts commit 49c458e544ae14514209ed80ea6829ca1b18ddf0. It seems to have some side effects in the non-kms cases. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-10-12drm/radeon/kms: Fix apparent typo in legacy CRTC memory bandwidth calculation.Michel Dänzer1-1/+1
While investigating the cause of CRTC FIFO underruns, I noticed that when converting the memory bandwidth calculation from the userspace X driver code, an instance of '8.0' was apparently accidentally converted to '80'.

2009-10-12drm/radeon/kms: Update memory bandwidth requirements in mode_set_base hook.Michel Dänzer2-4/+8
The hook may change the number of bytes per pixel being scanned out, which affects the CRTC memory bandwidth requirements. E.g. booting in 8bpp and then running X in 32bpp would result in the bandwidth requirements being underestimated for the latter and consequently in CRTC FIFO underruns causing visible artifacts with 3D intensive workloads. ATOM changes only compile-tested. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-10-12Revert "USB: Work around BIOS bugs by quiescing USB controllers earlier"Linus Torvalds1-1/+1
This reverts commit db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per http://bugzilla.kernel.org/show_bug.cgi?id=14374 http://marc.info/?l=linux-kernel&m=125446885705223&w=4 We simply can't do the USB handoff at FIXUP_HEADER time, since it will often require us to have valid IO mappings etc. But that in turn requires a whole different approach, not this trivial one-liner. Maybe we could teach all the USB quirk handoff handlers to only do the quirk if the device has all its registers set up (since if it isn't initialized, it's unlikely to be active), but regardless that will need a whole lot more code than just saying "let's do it really early". The proper fix is almost certainly to just leave the legacy IOMMU mappings active until after all devices have been initialized.

2009-10-10USB: serial: fix assumption that throttle/unthrottle cannot sleepOliver Neukum10-51/+37
many serial subdrivers are clearly written as if throttle/unthrottle cannot sleep. This leads to unneeded atomic submissions. This patch converts affected drivers in a way to makes very clear that throttle/unthrottle can sleep. Thus future misdesigns can be avoided and efficiency and reliability improved.

2009-10-10USB: ehci: Fix isoc scheduling boundary checking.Sarah Sharp1-0/+1
The EHCI driver does some bounds checking when it's scheduling an iTD for an active endpoint. It sets the local variable start to stream->next_uframe and moves that variable further in the schedule if necessary. However, the driver fails to do anything with start before jumping to the ready label and setting the URB's starting frame to stream->next_uframe. Alan Stern confirms the EHCI driver should set stream->next_uframe to start before jumping.

2009-10-10USB: storage: When a device returns no sense data, call it a Hardware ErrorAlan Stern1-7/+22
This patch (as1294) fixes a problem that has plagued users for several kernel releases. Some USB mass-storage devices don't return any sense data when they encounter certain kinds of errors. The SCSI layer interprets this to mean that the operation should be retried, and the same thing happens -- over and over again with no limit. In some circumstances (such as when a bus reset occurs) that is the right thing to do, but not here. The patch checks for this condition (a transport failure with no sense data) and changes the result code to DID_ERROR and the sense code to Hardware Error. This does get only a limited number of retries, and so the command will fail relatively quickly instead of getting stuck in an infinite loop. This fixes a large part of Bugzilla #14118.

2009-10-10USB: Fix throttling in generic usbserial driverJoris van Rantwijk1-1/+1
The generic usbserial driver in Linux 2.6.31 halts its receiving channel in response to throttle requests from the line discipline.

2009-10-10USB: xhci: Don't wait for a disable slot cmd when HC dies.Sarah Sharp1-0/+9
When the host controller dies or is removed while a device is plugged in, the USB core will attempt to deallocate the struct usb_device. That will call into xhci_free_dev(). This function used to attempt to submit a disable slot command to the host controller and clean up the device structures when that command returned. Change xhci_free_dev() to skip the command submission and just free the memory if the host controller died.

2009-10-10USB: xhci: Handle canceled URBs when HC dies.Sarah Sharp1-0/+12
When the host controller dies (e.g. it is removed from a PCI card slot), the xHCI driver cannot expect commands to complete. The buggy code this patch fixes would mark an URB as canceled and then expect the URB to be completed when the stop endpoint command completed. That would never happen if the host controller was dead, so the USB core would just hang in the disconnect code. If the host controller died, and the driver asks to cancel an URB, free any structures associated with that URB and immediately give it back.
