| | | | | | | | | | | | | | | | | | | | | | The unused space in the doorbell is now marked as RsvdZ, not RsvdP, so we can avoid reading the doorbell before writing it. Update the doorbell-related defines to produce the entire doorbell value from a single macro. Document the doorbell format in a comment.

| | | | | | | | | | | | | | | | | | | | | | | | | | giveback_first_trb() controls the cycle bit set of the start_trb, to ensure that the start_trb is written last and the host controller will receive a whole td at a time. However, if the ring is wrapped and cycle bit is toggled to zero, then giveback_first_trb() will be of no effect. In this case, set the cycle bit of start_trb to 1 at the beginning and clear it in giveback_first_trb().

| * xhci: Use GFP_NOIO during device reset.Sarah Sharp2011-01-141-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When xhci_discover_or_reset_device() is called after a host controller power loss, the virtual device may need to be reallocated. Make sure xhci_alloc_dev() uses GFP_NOIO. This avoid causing a deadlock by allowing the kernel to flush pending I/O while reallocating memory for a virtual device for a USB mass storage device that's holding the backing store for dirty memory buffers. This patch should be queued for the 2.6.37 stable tree. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@kernel.org
| * usb: Realloc xHCI structures after a hub is verified.Sarah Sharp2011-01-141-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there's an xHCI host power loss after a suspend from memory, the USB core attempts to reset and verify the USB devices that are attached to the system. The xHCI driver has to reallocate those devices, since the hardware lost all knowledge of them during the power loss. When a hub is plugged in, and the host loses power, the xHCI hardware structures are not updated to say the device is a hub. This is usually done in hub_configure() when the USB hub is detected. That function is skipped during a reset and verify by the USB core, since the core restores the old configuration and alternate settings, and the hub driver has no idea this happened. This bug makes the xHCI host controller reject the enumeration of low speed devices under the resumed hub. Therefore, make the USB core re-setup the internal xHCI hub device information by calling update_hub_device() when hub_activate() is called for a hub reset resume. After a host power loss, all devices under the roothub get a reset-resume or a disconnect. This patch should be queued for the 2.6.37 stable tree.

| * xhci: Resume bus on any port status change.Sarah Sharp2011-01-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original code that resumed the USB bus on a port status change would only do so when there was a device connected to the port. If a device was just disconnected, the event would be queued for khubd, but khubd wouldn't run. That would leave the connect status change (CSC) bit set. If a USB device was plugged into that same port, the xHCI host controller would set the current connect status (CCS) bit. But since the CSC bit was already set, it would not generate an interrupt for a port status change event. That would mean the user could "Safely Remove" a device, have the bus suspend, disconnect the device, re-plug it in, and then the device would never be enumerated. Plugging in a different device on another port would cause the bus to resume, and khubd would notice the re-connected device. Running lsusb would also resume the bus, leading users to report the problem "went away" when using diagnostic tools. The solution is to resume the bus when a port status change event is received, regardless of the port status. Thank you very much to Maddog for helping me track down this Heisenbug.

That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.

* | USB: ehci-fsl: Fix 'have_sysif_regs' detectionPeter Tyser2011-01-223-19/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously a check was done on an ID register at the base of a CPU's internal USB registers to determine if system interface regsiters were present. The check looked for an ID register that had the format ID[0:5] == ~ID[8:13] as described in the MPC5121 User's Manual to determine if a MPC5121 or MPC83xx/85xx was being used. There are two issues with this method: - The ID register is not defined on the MPC83xx/85xx CPUs, so its unclear what is being checked on them. - Newer CPUs such as the P4080 also don't document the ID register, but do share the same format as the MPC5121. Thus the previous code did not set 'have_sysif_regs' properly which results in the P4080 not properly initializing its USB ports. Using the device tree 'compatible' node is a cleaner way to determine if 'have_sysif_regs' should be set and resolves the USB initialization issue seen on the P4080. Tested on a P4080-based system and compile tested on mpc512x_defconfig with Freescale EHCI driver enabled.

* | kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
