* xhci: Fix bug in control transfer cancellation.Sarah Sharp2011-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the xHCI driver attempts to cancel a transfer, it issues a Stop Endpoint command and waits for the host controller to indicate which TRB it was in the middle of processing. The host will put an event TRB with completion code COMP_STOP on the event ring if it stops on a control transfer TRB (or other types of transfer TRBs). The ring handling code is supposed to set ep->stopped_trb to the TRB that the host stopped on when this happens. Unfortunately, there is a long-standing bug in the control transfer completion code. It doesn't actually check to see if COMP_STOP is set before attempting to process the transfer based on which part of the control TD completed. So when we get an event on the data phase of the control TRB with COMP_STOP set, it thinks it's a normal completion of the transfer and doesn't set ep->stopped_td or ep->stopped_trb. When the ring handling code goes on to process the completion of the Stop Endpoint command, it sees that ep->stopped_trb is not a part of the TD it's trying to cancel. It thinks the hardware has its enqueue pointer somewhere further up in the ring, and thinks it's safe to turn the control TRBs into no-op TRBs. Since the hardware was in the middle of the control TRBs to be cancelled, the proper software behavior is to issue a Set TR dequeue pointer command. It turns out that the NEC host controllers can handle active TRBs being set to no-op TRBs after a stop endpoint command, but other host controllers have issues with this out-of-spec software behavior. Fix this behavior. This patch should be backported to kernels as far back as 2.6.31, but it may be a bit challenging, since process_ctrl_td() was introduced in some refactoring done in 2.6.36, and some endian-safe patches added in 2.6.40 that touch the same lines.

* usb: gadget: composite: Allow function drivers to pause control transfersRoger Quadros2011-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.

Furthermore one of the two dump functions suffered from copy&paste fail. While staring at the code I've also noticed that the replace helper (currently unused) is a bit broken.

This bo is then freed at card shutdown. The problem is that the ttm bo vram manager was already freed. So a crash occurs when the vga bo is freed. The fix is to free the vga bo prior to freeing the ttm bo vram manager. There might be other solutions but this seemed the simplest to me.
