    dma_addr_t which may be of different sizes.

  • 8e4ff9b56   drm: Remove the dma_alloc_coherent wrapper for internal usage ... Browse Code »

    Internally for "consistent" maps, we create a temporary struct
    drm_dma_handle in order to use our own dma_alloc_coherent wrapper then
    destroy the temporary wrap. Simplify our logic by removing the temporary
    wrapper!

  • c76426883   drm: un-inline drm_legacy_findmap() ... Browse Code »

    Un-inline drm_legacy_findmap() to not depend on struct drm_device
    definition within drm_legacy.h, so that a forward declaration suffices.

    Also include drm_hashtab.h in drm_legacy.h to make it more
    self-contained. Make it easier to drop drmP.h includes.

    v2: avoid including drm_device.h by un-inlining (Daniel)

  • 3b96a0b14   drm: document drm_auth.c ... Browse Code »

    Also extract drm_auth.h for nicer grouping.

    v2: Nuke the other comments since they don't really explain a lot, and
    within the drm core we generally only document functions exported to
    drivers: The main audience for these docs are driver writers.

    v3: Limit the exposure of drm_master internals by only including
    drm_auth.h where it is neede (Chris).

    v4: Spelling polish (Emil).

  • 40647e45b   drm: Hide master MAP cleanup in drm_bufs.c ... Browse Code »

    And again make sure it's a no-op for modern drivers. Another case of
    dev->struct_mutex gone for modern drivers!

    Note that the entirety of the legacy addmap interface is now protected
    by DRIVER_MODESET. Note that just auditing kernel code is not enough,
    since userspace loves to set up legacy maps on it's own for various
    things - with ums userspace and kernel space share control over
    resources.

    v2: Also add a DRIVER_* check like for all other maps functions to
    really short-circuit the code. And give drm_legacy_rmmap used by the
    dev unregister code the same treatment.

    v3:
    - remove redundant return; (Alex, Chris)
    - don't special case nouveau with DRIVER_KMS_LEGACY_CONTEXT.

    v4: Again special case nouveau. The problem is not directly in the
    ddx, but that it calls dri1 functions from the X server. And those do
    call drmAddMap. Fixed only in

  • bfbf3c851   drm: move drm_mmap to <drm/drm_legacy.h> ... Browse Code »

    Now that we've removed the copypasted users in gem/ttm we can
    relegate the legacy buffer mapping support to where it belongs.
    Also give it the proper drm_legacy_ prefix.

    While at it statify drm_mmap_locked, somehow I've missed that in my
    previous header rework.
