  • This adds a generic uio driver that can bind to any PCI device. First
    user will be virtualization where a qemu userspace process needs to give
    guest OS access to the device.

    Interrupts are handled using the Interrupt Disable bit in the PCI
    command register and Interrupt Status bit in the PCI status register.
    All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI
    Express devices should support these bits. Driver detects this support,
    and won't bind to devices which do not support the Interrupt Disable Bit
    in the command register.

    It's expected that more features of interest to virtualization will be
    added to this driver in the future. Possibilities are: mmap for device
    resources, MSI/MSI-X, eventfd (to interface with kvm), iommu.

  • Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
    directory name to mount debugfs filesystem for ftrace according to
    ./Documentation/tracers/ftrace.txt file.

    And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
    existed in kernel source like ftrace, DRM, Wireless, Documentation,
    Network[sky2]files to mount debugfs filesystem.

    debugfs means debug filesystem for debugging easy to use by greg kroah
    hartman. "/sys/kernel/debug/" name is suitable as directory name
    of debugfs filesystem.
    - debugfs related reference: http://lwn.net/Articles/334546/

    Fix inconsistency of directory name to mount debugfs filesystem.

    * From Steven Rostedt
    - find_debugfs() and tracing_files() in this patch.

  • Moving information from config_interface to bss_info_changed
    removed struct ieee80211_if_conf which the documentation still
    refers to, additionally there's one kernel-doc description too
    much and one other missing, fix all this.

  • Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
    as correctly noted at bug #12454. Someone can lookup entry with NULL
    ->owner, thus not pinning enything, and release it later resulting
    in module refcount underflow.

    We can keep ->owner and supply it at registration time like ->proc_fops
    and ->data.

    But this leaves ->owner as easy-manipulative field (just one C assignment)
    and somebody will forget to unpin previous/pin current module when
    switching ->owner. ->proc_fops is declared as "const" which should give
    some thoughts.

    ->read_proc/->write_proc were just fixed to not require ->owner for
    protection.

    rmmod'ed directories will be empty and return "." and ".." -- no harm.
    And directories with tricky enough readdir and lookup shouldn't be modular.
    We definitely don't want such modular code.

    Removing ->owner will also make PDE smaller.

    So, let's nuke it.

    Kudos to Jeff Layton for reminding about this, let's say, oversight.

  • If a UIO device has several memory mappings, it can be difficult for userspace
    to find the right one. The situation becomes even worse if the UIO driver can
    handle different versions of a card that have different numbers of mappings.
    Benedikt Spranger has such cards and pointed this out to me. Thanks, Bene!

    To address this problem, this patch adds "name" sysfs attributes for each
    mapping. Userspace can use these to clearly identify each mapping. The name
    string is optional. If a driver doesn't set it, an empty string will be
    returned, so this patch won't break existing drivers.

    The same problem exists for port region information, so a "name" attribute is
    added there, too.
