  • 8369ae33b   bcma: add Broadcom specific AMBA bus driver ... Browse Code »

    Broadcom has released cards based on a new AMBA-based bus type. From a
    programming point of view, this new bus type differs from AMBA and does
    not use AMBA common registers. It also differs enough from SSB. We
    decided that a new bus driver is needed to keep the code clean.

    In its current form, the driver detects devices present on the bus and
    registers them in the system. It allows registering BCMA drivers for
    specified bus devices and provides them basic operations. The bus driver
    itself includes two important bus managing drivers: ChipCommon core
    driver and PCI(c) core driver. They are early used to allow correct
    initialization.

    Currently code is limited to supporting buses on PCI(e) devices, however
    the driver is designed to be used also on other hosts. The host
    abstraction layer is implemented and already used for PCI(e).

    Support for PCI(e) hosts is working and seems to be stable (access to
    80211 core was tested successfully on a few devices). We can still
    optimize it by using some fixed windows, but this can be done later
    without affecting any external code. Windows are just ranges in MMIO
    used for accessing cores on the bus.

  • 0a14842f5   net: filter: Just In Time compiler for x86-64 ... Browse Code »

    In order to speedup packet filtering, here is an implementation of a
    JIT compiler for x86_64

    It is disabled by default, and must be enabled by the admin.

    echo 1 >/proc/sys/net/core/bpf_jit_enable

    It uses module_alloc() and module_free() to get memory in the 2GB text
    kernel range since we call helpers functions from the generated code.

    EAX : BPF A accumulator
    EBX : BPF X accumulator
    RDI : pointer to skb (first argument given to JIT function)
    RBP : frame pointer (even if CONFIG_FRAME_POINTER=n)
    r9d : skb->len - skb->data_len (headlen)
    r8 : skb->data

    To get a trace of generated code, use :

    echo 2 >/proc/sys/net/core/bpf_jit_enable

    Example of generated code :

    # tcpdump -p -n -s 0 -i eth1 host 192.168.20.0/24

    flen=18 proglen=147 pass=3 image=ffffffffa00b5000

  • b229ece99   asus-nb-wmi: Asus Notebooks WMI Driver ... Browse Code »

    Introduce a new driver for Asus Notebooks shipped with
    a WMI device instead of the old ACPI device. The WMI
    device is almost the same as the one present in Eee PC,
    but the event guid and the keymap are different.

    The keymap comes from asus-laptop module.

    On Asus notebooks, when you call the WMI device, you always
    need a 64bit buffer, even if you only want to get the state
    of a device (tested on a G73).

    I no longer have access to any hardware that uses APM and have not
    provided real maintenance for several years. Hopefully someone with the
    hardware or energy will step forward if the driver is to be kept.
