OK, looks like we've got the XHCI power management patches upstream in 2.6.37-rc1:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=5cc103506289de7ee0a0b526ae0381541990cad4 Unfortunately, it looks like there's be quite a few xhci updates to backport if we were looking to add USB 3 suspend/resume to Maverick. These are the xhci-specific changes between maverick and current upstream head: 436a389 usb: Fix linker errors with CONFIG_PM=n b5b5c3a USB: xhci: Fix compile error when CONFIG_PM=n 5535b1d USB: xHCI: PCI power management implementation 9777e3c USB: xHCI: bus power management implementation 5619253 USB: xHCI: port remote wakeup implementation be88fe4 USB: xHCI: port power management implementation c8d4af8 USB: core: use kernel assigned address for devices under xHCI f0615c4 USB: xHCI: change xhci_reset_device() to allocate new device 6492773 USB: xHCI: Add pointer to udev in struct xhci_virt_device 14184f9 USB: xHCI: update ring dequeue pointer when process missed tds a1669b2 USB: xhci: Remove buggy assignment in next_trb() 006d582 USB: xhci: Set DMA mask for host. ed3f245 USB: xhci: Don't flush doorbell writes. c21599a USB: xhci: Reduce reads and writes of interrupter registers. 257d585 USB: xhci: Make xhci_set_hc_event_deq() static. c06d68b USB: xhci: Minimize HW event ring dequeue pointer writes. d6d98a4 USB: xhci: Make xhci_handle_event() static. 27e0dd4 USB: xhci: Remove unnecessary reads of IRQ_PENDING register. bda5314 USB: xhci: Performance - move xhci_work() into xhci_irq() 9032cd5 USB: xhci: Performance - move interrupt handlers into xhci-ring.c 021bff9 USB: xhci: Performance - move functions that find ep ring. 787f4e5 USB: xHCI: Isoc urb enqueue a061a5a USB: xHCI: allocate bigger ring for isochronous endpoint 04e5190 USB: xHCI: Isochronous transfer implementation 8e51adc USB: xHCI: Introduce urb_priv structure d18240d USB: xHCI: Missed Service Error Event process 986a92d USB: xHCI: adds new cases to trb_comp_code switch 7fec325 USB: xHCI: remove redundant print messages 22405ed USB xHCI: handle_tx_event() refactor: process_bulk_intr_td 8af56be USB: xHCI: handle_tx_event() refactor: process_ctrl_td 4422da6 USB: xHCI: handle_tx_event() refactor: finish_td 43b86af USB: xHCI: Supporting MSI/MSI-X e10fa47 USB: xhci: trivial: use ARRAY_SIZE 541c7d4 USB: convert usb_hcd bitfields into atomic flags 202380d USB: xhci: Remove obsolete debugging printk. - these changes don't apply directly to the maverick kernel; we'd probably need quite a bit of munging and cherry-picking other patches to get these applied. We *may* be able to just grab the "power management implementation" patches, but we might be missing some important fixes in this case. I'll have an initial look and see if this is feasible. In general, I'd strongly suggesting sticking to Natty for devices where 3.0 support is necessary. -- XHCI (USB 3.0) kernel Module Prevents Suspend https://bugs.launchpad.net/bugs/522998 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
