  • caf02abf9   PCI: Add QEMU top-level IDs for (sub)vendor & device ... Browse Code »

    Introduce PCI_VENDOR/PCI_SUBVENDOR/PCI_SUBDEVICE defines to replace the
    constants scattered in the kernel already used to detect QEMU.

    They are defined in the QEMU codebase per docs/specs/pci-ids.txt.

  • 2989be09a   virtio_pci: fix use after free on release ... Browse Code »

    KASan detected a use-after-free error in virtio-pci remove code. In
    virtio_pci_remove(), vp_dev is still used after being freed in
    unregister_virtio_device() (in virtio_pci_release_dev() more
    precisely).

    To fix, keep a reference until cleanup is done.

  • f7ad26ff9   virtio: make find_vqs() checkpatch.pl-friendly ... Browse Code »

    checkpatch.pl wants arrays of strings declared as follows:

    static const char * const names[] = { "vq-1", "vq-2", "vq-3" };

    Currently the find_vqs() function takes a const char *names[] argument
    so passing checkpatch.pl's const char * const names[] results in a
    compiler error due to losing the second const.

    This patch adjusts the find_vqs() prototype and updates all virtio
    transports. This makes it possible for virtio_balloon.c, virtio_input.c,
    virtgpu_kms.c, and virtio_rpmsg_bus.c to use the checkpatch.pl-friendly
    type.

    Pull virtio/vhost cross endian support from Michael Tsirkin:
    "I have just queued some more bugfix patches today but none fix
    regressions and none are related to these ones, so it looks like a
    good time for a merge for -rc1.

    The motivation for this is support for legacy BE guests on the new LE
    hosts. There are two redeeming properties that made me merge this:

    - It's a trivial amount of code: since we wrap host/guest accesses
    anyway, almost all of it is well hidden from drivers.

    - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY,
    and when it's clear, there's zero overhead (as some point it was
    tested by compiling with and without the patches, got the same
    stripped binary).

    Maybe we could create a Kconfig symbol to enforce the second point:
    prevent people from enabling it eg on x86. I will look into this"

    Move resource allocation from common code to legacy and modern code.
    Only request resources actually used, i.e. bar0 in legacy mode and
    the bar(s) specified by capabilities in modern mode.
