  • 9baa3c34a   PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use ... Browse Code »

    We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
    meet kernel coding style guidelines. This issue was reported by checkpatch.

    A simplified version of the semantic patch that makes this change is as
    follows (http://coccinelle.lip6.fr/):

    //

    @@
    identifier i;
    declarer name DEFINE_PCI_DEVICE_TABLE;
    initializer z;
    @@

    - DEFINE_PCI_DEVICE_TABLE(i)
    + const struct pci_device_id i[]
    = z;

    Pull ARM SoC cleanups from Olof Johansson:
    "This merge window brings a good size of cleanups on various platforms.
    Among the bigger ones:

    - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
    have lacked active support for quite a while, and after asking
    around nobody showed interest in keeping them around. If needed,
    they could be resurrected in the future but it's more likely that
    we would prefer reintroduction of them as DT and
    multiplatform-enabled platforms instead.

    - OMAP4 controller code register define diet. They defined a lot of
    registers that were never actually used, etc.

    - Move of some of the Tegra platform code (PMC, APBIO, fuse,
    powergate) to drivers/soc so it can be shared with 64-bit code.
    This also converts them over to traditional driver models where
    possible.

    - Removal of legacy gpio-samsung driver, since the last users have
    been removed (moved to pinctrl)

    Plus a bunch of smaller changes for various platforms that sort of
    dissapear in the diffstat for the above. clps711x cleanups, shmobile

    After v3.16-rc1, devices populated with of_platform_populate() should be

    Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM
    panic because the notification work is done in a workqueue, and in panic() the
    kernel typically ends up in an infinite loop, and a typical kernel config has
    CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch
    can't happen in panic() and the workqueue won't have a chance to run. As a
    result, the VM Connection window can't refresh until it's closed and we
    re-connect to the VM.

    We can register a handler on panic_notifier_list: the handler can notify
    the VSC and switch the framebuffer driver to a "synchronous mode", meaning
    the VSC flushes any future framebuffer change to the VSP immediately.

    v2: removed the MS-TFS line in the commit message
    v3: remove some 'unlikely' markings
    v4: avoid global variables as Tomi Valkeinen suggested

    The Versatile CLCD helpers call dma_alloc_writecombine() which is only
    available on ARM and AVR32, meaning they won't build on other platforms
    including arm64. Unfortunately the current Kconfig enables the symbol
    by default if ARCH_VEXPRESS is defined which means that it is enabled on
    arm64 when building for the ARM reference platforms and models for ARMv8
    since they have many hardware similarities with their pre-ARMv8 systems.

    Since all the systems that need the helpers are ARM systems fix this by
    adding a dependency on ARM.

    commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers")
    moved files out of the plat-versatile directory but in the process
    got a few of the dependencies wrong:

    - If CONFIG_FB is not set, the file no longer gets built, resulting
    in a link error
    - If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a
    Kconfig warning for incorrect dependencies due to the symbol
    being 'select'ed from the platform Kconfig.
    - When the file is not built, we also get a link error for missing
    symbols.

    This patch should fix all three, by removing the 'select' statements,
    changing the Kconfig description of the symbol to be enabled in
    exactly the right configurations, and adding inline stub functions
    for the case when the framebuffer driver is disabled.

  • 20cde6940   x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup() ... Browse Code »

    Commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)") added
    efifb vga_default_device() so EFI systems that do not load shadow VBIOS or
    setup VGA get proper value for boot_vga PCI sysfs attribute on the
    corresponding PCI device.

    Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such
    as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then
    bails out with "no devices detected".

    Note: When vga_default_device() is set boot_vga PCI sysfs attribute
    reflects its state. When unset this attribute is 1 whenever
    IORESOURCE_ROM_SHADOW flag is set.

    With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
    while having native drivers for the GPU also makes selecting sysfb/efifb
    optional.

    Remove the efifb implementation of vga_default_device() and initialize
    vgaarb's vga_default_device() with the PCI GPU that matches boot
    screen_info in pci_fixup_video().

    The atmel-pwm-bl driver is now obsolete. It is not used by any mainlined boards
    and is replaced by the generic pwm_bl with the pawm-atmel driver using the
    generic PWM framework.
