  • b7e5d1f04   ramoops: add HAS_IOMEM dependency ... Browse Code »

    The driver fails to compile on s390:

    drivers/char/ramoops.c: In function 'ramoops_init':
    drivers/char/ramoops.c:122: error: implicit declaration of function 'ioremap'

    Since we won't make use of the driver anyway on s390 just let it depend on
    HAS_IOMEM.

  • 56d611a04   char drivers: RAM oops/panic logger ... Browse Code »

    Ramoops, like mtdoops, can log oops/panic information but in RAM. It can
    be used with persistent RAM for systems without flash support. In
    addition, for this systems, with this driver, it's no more needed add to
    the kernel the mtd subsystem with advantage in footprint.

    It can be used in a very easy way with persistent RAM for systems without
    flash support. For these systems, with this driver, it is no longer
    required to cinlude mtd subsystem with an advantage in footprint. In
    addition, you can save flash space and store this information only in RAM.

    Add an implementation of GSM 0710 MUX. The implementation currently supports

    - Basic and advanced framing (as either end of the link)
    - UI or UIH data frames
    - Adaption layer 1-4 (1 and 2 via tty, 3 and 4 as skbuff lists)
    - Modem and control messages including the correct retry process
    - Flow control

    and exposes the MUX channels as a set of virtual tty devices including modem
    signals. This is an experimental driver.

  • fb08bd274   virtio: console: Associate each port with a char device ... Browse Code »

    The char device will be used as an interface by applications on the
    guest to communicate with apps on the host.

    The devices created are placed in /dev/vportNpn where N is the
    virtio-console device number and n is the port number for that device.

    One dynamic major device number is allocated for each device and minor
    numbers are allocated for the ports contained within that device.

    The file operation for the char devs will be added in the following
    commits.

  • 44a01d5ba   [S390] s390/hvc_console: z/VM IUCV hypervisor console support ... Browse Code »

    This patch introduces a new hypervisor console (HVC) back-end that provides
    terminal access over the z/VM inter-user communication vehicle (IUCV).

    The z/VM IUCV communication is independent of the regular tcp/ip network
    and allows access even if there is no network connection between two
    z/VM guest virtual machines.
    The z/VM IUCV hypervisor console back-end helps the user to access a
    z/VM guest virtual machine that lacks of network connectivity; and thus,
    provides a "full-screen" terminal alternative to 3215/3270 terminal sessions.

    Use the hvc_iucv=[0..8] kernel boot parameter to specify the number of
    HVC terminals using a z/VM IUCV back-end.

    A recent version of the s390-tools package is required to establish a
    terminal connection to a z/VM IUCV hypervisor console back-end.

  • d5e549134   powerpc: udbg-based backend for hvc_console ... Browse Code »

    This adds a new backend for the hvc console based on the low-level
    udbg callbacks. This effectively implements a working runtime console
    in terms of the simple udbg primitives. This is kind of a hack -
    since udbg isn't something you really want to be using routinely - but
    it's really useful during bringup.

    This can be used to quickly implement a userspace-usable console while
    you're working on a proper driver for whatever console I/O device the
    hardware has. Or, it can be used to avoid writing a full blown
    tty/console driver entirely for quick-and-dirty I/O hardware that will
    later be replaced by something else.

  • 0f4d3fd8a   legacy rtc: remove needless/confusing HPET_RTC_IRQ option ... Browse Code »

    HPET_RTC_IRQ is no longer needed; HPET_EMULATE_RTC suffices and is more
    correct. (http://bugzilla.kernel.org/show_bug.cgi?id=11111)

    Note that when using the legacy RTC driver, platforms don't really do a
    dynamic switch between HPET and non-HPET modes based on whether HPET
    hardware actually exists ... only rtc-cmos (using the new RTC framework)
    currently switches that way.

    So this reflects bitrot in that legacy code, for x86/ia64: kernels with
    HPET support configured (e.g. for a clocksource) can't get IRQs from the
    legacy RTC driver unless they really have HPET hardware. (The obvious
    workaround is to not use the legacy RTC driver on those platforms when you
    configure HPET ... unless you know the target really has a HPET.)

  • 611e097d7   hvc_console: rework setup to replace irq functions with callbacks ... Browse Code »

    This patch tries to change hvc_console to not use request_irq/free_irq if
    the backend does not use irqs. This allows virtio_console to use hvc_console
    without having a linker reference to request_irq/free_irq.

    In addition, together with patch 2/3 it improves the performance for virtio
    console input. (an earlier version of this patch was tested by Yajin on lguest)

    The irq specific code is moved to hvc_irq.c and selected by the drivers that
    use irqs (System p, System i, XEN).

    I replaced "int irq" with the opaque "int data". The request_irq and
    free_irq calls are replaced with notifier_add and notifier_del. I have also
    changed the code a bit to call the notifier_add and notifier_del inside the
    spinlock area as the callbacks are found via hp->ops.

    Changes since last version:
    o remove ifdef
    o reintroduce "irq_requested" as "notified"
    o cleanups, sparse..

    I did not move the timer based polling into a separate polling scheme. I
    played with several variants, but it seems we need to sleep/schedule in
    a thread even for irq based consoles, as there are throttleing and buffer
    size constraints.

    I also kept hvc_struct defined in hvc_console.h so that hvc_irq.c can access
    the irq_requested element.

    Feedback is appreciated. virtio_console is currently the only available console
    for kvm on s390. I plan to push this change as soon as all affected parties
    agree on it. I would love to get test results from System p, Xen etc.
