It is true that BM_RLD needs to be set to enable bus master activity to wake an older chipset (eg PIIX4) from C3. This is contrary to the erroneous wording the ACPI 2.0, 3.0 specifications that suggests that BM_RLD is an indicator rather than a control bit. ACPI 1.0's correct wording should be restored in ACPI 4.0: http://www.acpica.org/bugzilla/show_bug.cgi?id=689 But the kernel should not have to clear BM_RLD when entering a non C3-type state just to set it again when entering a C3-type C-state. We should be able to set BM_RLD at boot time and leave it alone -- removing the overhead of accessing this IO register from the idle entry path. Signed-off-by:

PM1a_STS and PM1b_STS are twins that get OR'd together on reads, and all writes are repeated to both. The fields in PM1x_STS are single bits only, there are no multi-bit fields. So it is not necessary to lock PM1x_STS reads against writes because it is impossible to read an intermediate value of a single bit. It will either be 0 or 1, even if a write is in progress during the read. Reads are asynchronous to writes no matter if a lock is used or not. Signed-off-by: -

Given just how hard it is to find the code that uses MAY_APPEND it's probably not a big surprise that this went unnoticed for so long. The Smack rules loading code is incorrectly setting the MAY_READ bit when MAY_APPEND is requested. Signed-off-by:

This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device. Signed-off-by:

The ZTE modem entry causes usb-storage to ignore the device, but for some versions of the device, usb-storage mode is required to get to modem ode. For both kinds the tool: http://www.draisberghof.de/usb_modeswitch/ should work. Note that the various versions of the device have the same ProductId, VendorId, and bcdDevice number, so we cannot have the entry for some and not others. Signed-off-by:

My Brother HL-1440 would print one document before CUPS would stop printing with the error "Printer not connected; will retry in 30 seconds...". I traced this down to the CUPS usb backend getting an EIO out of usblp on the IOCNR_GET_DEVICE_ID IOCTL. Adding the USBLP_QUIRK_BIDIR fixes the problem but is it the right solution? output from strace /usr/lib/cups/backend/usb after printing a document (Note: SNDCTL_DSP_SYNC == IOCNR_GET_DEVICE_ID): before patch open("/dev/usb/lp0", O_RDWR|O_EXCL) = 3 ioctl(3, SNDCTL_DSP_SYNC, 0x7fff2478cef0) = -1 EIO (Input/output error) after patch open("/dev/usb/lp0", O_RDWR|O_EXCL) = 3 ioctl(3, SNDCTL_DSP_SYNC, 0x7fffb8d474c0) = 0 Possibly related bug: https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/35638Signed-off-by:

This patch (as1198) fixes a conceptual bug: Somewhere along the line we managed to confuse USB class devices with USB char devices. As a result, the code to send a disconnect signal to userspace would not be built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were disabled. The usb_fs_classdev_common_remove() routine has been renamed to usbdev_remove() and it is now called whenever any USB device is removed, not just when a class device is unregistered. The notifier registration and unregistration calls are no longer conditionally compiled. And since the common removal code will always be called as part of the char device interface, there's no need to call it again as part of the usbfs interface; thus the invocation of usb_fs_classdev_common_remove() has been taken out of usbfs_remove_device().

Commit a0d4922d (USB: fix up suspend and resume for PCI host controllers) attempted to fix the suspend-resume of PCI USB controllers, but unfortunately it did that incorrectly and interrupts are left enabled by the USB controllers' ->suspend_late() callback as a result. This leads to serious problems during suspend which are very difficult to debug. Fix the issue by removing the ->suspend_late() callback of PCI USB controllers and moving the code from there to the ->suspend() callback executed with interrupts enabled. Additionally, make the ->resume() callback of PCI USB controllers execute pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the full power state (PCI_D0). Signed-off-by:

This patch (as1199) changes the initial wakeup settings for PCI USB host controllers. The controllers are marked as capable of waking the system, but wakeup is not enabled by default. It turns out that enabling wakeup for USB host controllers has a lot of bad consequences. As the simplest example, if a USB mouse or keyboard is unplugged immediately after the computer is put to sleep, the unplug will cause the system to wake back up again! We are better off marking them as wakeup-capable and leaving wakeup disabled. Signed-off-by:

This patch (as1200) finishes some fixes that were left incomplete by an earlier patch. Although nobody has addressed this issue in the past, it turns out that we need to distinguish between two different modes of disabling and enabling endpoints. In one mode only the data structures in usbcore are affected, and in the other mode the host controller and device hardware states are affected as well. The earlier patch added an extra argument to the routines in the enable_endpoint pathways to reflect this difference. This patch adds corresponding arguments to the disable_endpoint pathways. Without this change, the endpoint toggle state can get out of sync between the host and the device. The exact mechanism depends on the details of the host controller (whether or not it stores its own copy of the toggle values). Signed-off-by:
