composite.c always sets req->length to zero

w_length will always be greater than req->length
thus making us always stall that particular

  xhci: Fix bug in control transfer cancellation.
2011-05-12 09:39:31 -07:00
Sarah Sharp
3abeca998a xhci: Fix bug in control transfer cancellation.
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.

1b9ba00017 usb: gadget: composite: Allow function drivers to pause control transfers
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.

ad106f2923 xHCI 1.0: Block Interrupts for Isoch transfer
Currently an isoc URB is divided into multiple TDs, and every TD will
trigger an interrupt when it's processed. However, software can schedule
multiple TDs at a time, and it only needs an interrupt every URB.

xHCI 1.0 introduces the Block Event Interrupt(BEI) flag which allows Normal
and Isoch Transfer TRBs to place an Event TRB on an Event Ring but not
assert an intrrupt to the host, and the interrupt rate is significantly
reduced and the system performance is improved.

This patch also extends the uhci_{read,write}* functions to allow accesses

the addition of a void __iomem pointer to the uhci structure.

A new Kconfig option is added to signal that the system has a non-PCI HC.
If this Kconfig option is set, uhci-hcd.c will include generic reset functions
for systems that do not make use of keyboard and mouse legacy support. PCI
controllers will still always use the reset functions from pci-quirks

functions. This is done so that the register access functions can be
extended to support register areas not mapped in PCI I/O space.

c31a65f869 USB: UHCI: Move PCI specific functions to uhci-pci.c
This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.

This patch moves PCI specific functions to uhci-pci.c and includes
this file in uhci-hcd.c. It also renames the function uhci_init to
uhci_pci_init.

uhci_init/uhci_pci_init is modified so that the port-detection logic
is kept in a new separate function uhci_count_ports() in uhci-hcd.c.

e7652e1ebc USB: UHCI: Allow dynamic assignment of bus specific functions
This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.

This patch changes calls to uhci_reset_hc, uhci_check_and_reset_hc,
configure_hc, resume_detect_interrupts_are_broken and
global_suspend_mode_is_broken so that they are made through pointers
in the uhci hcd struct. This will allow these functions to be replaced
with bus/arch specific functions.

dfeca7a875 USB: UHCI: Remove PCI dependencies from uhci-hub
This patch is part of a series that extend the UHCI HCD to support
non-PCI host controllers.

uhci-hub.c contained two PCI vendor checks for silicon quirks. Move
these checks into uhci-hcd.c and use bits in uhci_hcd structure to
mark that we need to use the quirks.

This patch is followed by other patches that will remove PCI
dependencies from uhci-hcd.c as well.

ea437f3923 fsl/usb: Unused endpoint failure for USB gadget
Though USB controller works without this most of the time, an issue was faced
where USB was configured as printer device and it was dropping first
packet(64 bytes) in full speed mode due to DATA PID mismatch.
The problem gets resolved once unused endpoints are configured as bulk.
As per P1020 RM (Table17-31, bits 19-18, bits 3-2) "When only one endpoint
(RX or TX, but not both) of an endpoint pair is used, the unused endpoint
should be configured as a bulk type endpoint." So according to the RM,
this patch is initializing TX and RX endpoints as bulk type
