  • 152cce000   drm/bridge: analogix_dp: Split bind() into probe() and real bind() ... Browse Code »

    Analogix_dp driver acquires all its resources in the ->bind() callback,
    what is a bit against the component driver based approach, where the
    driver initialization is split into a probe(), where all resources are
    gathered, and a bind(), where all objects are created and a compound
    driver is initialized.

    Extract all the resource related operations to analogix_dp_probe() and
    analogix_dp_remove(), then call them before/after registration of the
    device components from the main Exynos DP and Rockchip DP drivers. Also
    move the plat_data initialization to the probe() to make it available for
    the analogix_dp_probe() function.

    This fixes the multiple calls to the bind() of the DRM compound driver
    when the DP PHY driver is not yet loaded/probed:

  • b513b0d45   drm/virtio: fix OOB in virtio_gpu_object_create ... Browse Code »

    After commit f651c8b05542 ("drm/virtio: factor out the sg_table from
    virtio_gpu_object"), virtio_gpu_create_object allocates too small space
    to fit everything in. It is because it allocates struct
    virtio_gpu_object, but should allocate a newly added struct
    virtio_gpu_object_shmem which has 2 more members.

    So fix that by using correct type in virtio_gpu_create_object.

  • c0f83d164   drm/prime: fix extracting of the DMA addresses from a scatterlist ... Browse Code »

    Scatterlist elements contains both pages and DMA addresses, but one
    should not assume 1:1 relation between them. The sg->length is the size
    of the physical memory chunk described by the sg->page, while
    sg_dma_len(sg) is the size of the DMA (IO virtual) chunk described by
    the sg_dma_address(sg).

    The proper way of extracting both: pages and DMA addresses of the whole
    buffer described by a scatterlist it to iterate independently over the
    sg->pages/sg->length and sg_dma_address(sg)/sg_dma_len(sg) entries.

    Fixes: 42e67b479eab ("drm/prime: use dma length macro when mapping sg")

  • d6e7042f4   drm/amd/display: increase HDCP authentication delay ... Browse Code »

    [Why]
    Some displays have an issue where the hdcp chips are initialized after the
    display has already lit up. This means we can sometimes authentication too early
    and cause authentication failures.

    This happens when HDCP is enabled and the display is power cycled. Normally we
    will authenticate 2 seconds after the display is lit, but some displays need a
    bit more time.

    [How]
    Increase delay to 3 second before we start authentication.

    [Why]
    When content type property is set to 1. We should enable hdcp2.2 and if we cant
    then stop. Currently the way it works in DC is that if we fail hdcp2, we will
    try hdcp1 after.

    [How]
    Use link config to force disable hdcp1.4 when type1 is set.

  • 9941b8129   drm/amd/display: Not doing optimize bandwidth if flip pending. ... Browse Code »

    [Why]
    In some scenario like 1366x768 VSR enabled connected with a 4K monitor
    and playing 4K video in clone mode, underflow will be observed due to
    decrease dppclk when previouse surface scan isn't finished

    [How]
    In this use case, surface flip is switching between 4K and 1366x768,
    1366x768 needs smaller dppclk, and when decrease the clk and previous
    surface scan is for 4K and scan isn't done, underflow will happen. Not
    doing optimize bandwidth in case of flip pending.
