* | USB SL811HS HCD: Fix memory leak in sl811h_urb_enqueue()Jesper Juhl2011-02-03
|/ | | | | | | | | | | | | In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope without having been assigned to anything, so we'll leak the memory we allocated. This patch fixes the leak by simply calling kfree(ep); before jumping to the 'fail' label. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * xhci: Resume bus on any port status change.Sarah Sharp2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

By default i.MX OTG port is configured for USB serial PHY. In order to use a ULPI PHY the PORTSCx register needs to be configured properly. commit 724c852 (USB: ehci/mxc: compile fix) placed the PORTSC setup after the OTG viewport is accessed and this causes ULPI read/write to fail. Revert the PORTSC setup order.

The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings.
