  • a500e0e73   Drivers: hv: kvp: Copy the address family information ... Browse Code »

    This is part of the IP injection protocol in that the host expects this field
    to reflect what addresses (address families) are currently bound to the
    interface. The KVP daemon is currently collecting this information and sending
    it to the kernel component. I had overlooked copying this and sending it
    back to the host. This patch addresses this issue.

  • 1f94ea818   hv: vmbus_drv: detect hyperv through x86_hyper ... Browse Code »

    There are two reasons we need to use x86_hyper instead of
    query_hypervisor_presence():

    - Not only hyperv but also other hypervisors such as kvm would set
    X86_FEATURE_HYTPERVISOR, so query_hypervisor_presence() will return true even
    in kvm. This may cause extra delay of 5 seconds before failing the probing in
    kvm guest.
    - The hypervisor has been detected in init_hypervisor(), so no need to do the
    work again.

    We wait for about 5 seconds for the success of the hyperv registration even if
    we were not in hyperv platform. This is suboptimal, so the patch check the cpuid
    in the beginning of hv_acpi_init() instead of in vmbus_bus_init() to fail the
    probing immediately.

    The current guest ID string in use in vmbus driver does not conform
    to the MSFT guidelines on guest ID. MSFT currently does not specify
    Linux specific guidelines. MSFT however has plans to publish Linux
    specific guidelines. This implementation conforms to the yet unpublished
    Linux specific guidelines for guest ID. This implementation also broadly
    conforms to the current guidelines as well.

    With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
    no-op; interrupt randomness is now collected unconditionally in a very
    low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM
    flag was scheduled to be removed in 2009 on the
    feature-removal-schedule, so this patch is preparation for the final

    In the existing code, we only stop queue when the ringbuffer is full,
    so the current packet has to be dropped or retried from upper layer.

    This patch stops the tx queue when available ringbuffer is below
    the low watermark. So the ringbuffer still has small amount of space
    available for the current packet. This will reduce the overhead of
    retries on sending.

  • 14c1bf8a8   drivers: hv: Increase the number of VCPUs supported in the guest ... Browse Code »

    The current code arbirarily limited the number of CPUs the guest could have.
    Change that so that we can support the maximum number of CPUs the guest can
    support. While we use NR_CPUS to size the per-cpu state all we are allocating
    based on NR_CPUS are the pointers to per-cpu state that will be allocatted in
    the context of the initializing CPU. This patch triggers a checkpatch warning
    for the usage of NR_CPU and since all we are allocating a couple of pointers
    per CPU, it should be ok.

    The function vmbus_exists() was introduced recently to deal with cases where
    the vmbus driver failed to initialize and yet other Hyper-V drivers attempted
    to register with the vmbus bus driver. This patch introduced a bug where
    vmbus_driver_unregister() would fail to unregister the driver. This patch
    fixes the problem.

  • 0720a06a7   NLS: improve UTF8 -> UTF16 string conversion routine ... Browse Code »

    The utf8s_to_utf16s conversion routine needs to be improved. Unlike
    its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
    the maximum length of the output buffer or the endianness of its
    16-bit output.

    This patch (as1501) adds the two missing arguments, and adjusts the
    only two places in the kernel where the function is called. A
    follow-on patch will add a third caller that does utilize the new
    capabilities.

    The two conversion routines are still annoyingly inconsistent in the
    way they handle invalid byte combinations. But that's a subject for a
    different patch.
