  • a64882e79   [PATCH] ACPI: fix sleeping whilst atomic warnings on resume ... Browse Code »

    This has been broken for months. On resume, we call acpi_pci_link_set()
    with interrupts off, so we get a warning when we try to do a kmalloc of non
    atomic memory. The actual allocation is just 2 long's (plus extra byte for
    some reason I can't fathom), so a simple conversion to GFP_ATOMIC is
    probably the safest way to fix this.

    The error looks like this..

    Debug: sleeping function called from invalid context at mm/slab.c:2486
    in_atomic():0, irqs_disabled():1
    [] kmem_cache_alloc+0x40/0x56
    [] acpi_pci_link_set+0x3f/0x17f
    [] irqrouter_resume+0x1e/0x3c
    [] __sysdev_resume+0x11/0x6b
    [] sysdev_resume+0x34/0x52
    [] device_power_up+0x5/0xa

  • 697a2d63a   Revert ACPI interrupt resume changes ... Browse Code »

    If there are devices that use interrupts over a suspend event, ACPI must
    restore the PCI interrupt links on resume. Anything else breaks any
    device that hasn't been converted to the new (dubious) PM rules.

    Drivers that need the irq free/re-aquire sequence can be done one by one
    independently of this one.

    Delete PCI Interrupt Link Device .resume method --
    it is the device driver's job to request interrupts,
    not the Link's job to remember what the devices want.

    This addresses the issue of attempting to run
    the ACPI interpreter too early in resume, when
    interrupts are still disabled.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
