  • Driver to communicate with SECO over messaging unit.
    Expose a char device to user-space so user can write messages that
    will be sent to SECO and read messages received from it.
    Data that should be exchanged with SECO through shared memory are
    indicated to this driver through ioctl calls.

  • If CRTC is active, we should send vblank event in vblank
    interrupt handler to make sure it's sent precisely. This
    patch caches the event to be sent at dpu_crtc->event in
    the ->atomic_enable() and the ->atomic_flush() callbacks
    and finally sends it out in dpu_vbl_irq_handler(). Since
    we rely on the interrupt handler to send the event, we
    call drm_crtc_vblank_get() to get a vblank refcount to
    guarantee the interrupt is enabled when caching the event
    in dpu_crtc_queue_state_event() and call drm_crtc_vblank_put()
    to drop a vblank refcount in the interrupt handler.

  • The DRM atomic core ensures crtc->state->event is not NULL when
    calling the ->atomic_disable() or the ->atomic_flush() callbacks.
    So, let's remove the unnecessary NULL check warning on it.

  • When a full modeset is needed, the CRTC could be totally disabled or
    enabled/re-enabled after the modeset. If it's re-enabled, a vblank
    event would be sent during the CRTC enablement procedure. So, a bogus
    event should be killed in the ->atomic_disable() callback.

  • The Kdoc for the event entry of struct drm_crtc_state mentions that the
    simplest way to send vblank event when a CRTC is being disabled is that
    calling drm_crtc_send_vblank_event() somewhen after drm_crtc_vblank_off()
    has been called. This patch takes the way mentioned above to send vblank
    event in the ->atomic_disable() callback.

  • As DPU fetchunits support ITU601(limited range)/ITU601_FR(full range)
    and ITU709(limited range) YUV to RGB color space conversions, we may
    add color encoding and color range properties support for planes.
    Considering software backward compatibility, the default color encoding
    is set to ITU601 with full color range.

  • Without the new blend modes("None", "Pre-multiplied" and "Coverage")

  • Pixel blend modes represent the alpha blending equation
    selection, describing how the pixels from the current
    plane are composited with the background.

    Adds a pixel_blend_mode to drm_plane_state and a
    blend_mode_property to drm_plane, and related support
    functions.

    Defines three blend modes in drm_blend.h.

    Changes since v1:
    - Moves the blending equation into the DOC comment
    - Refines the comments of drm_plane_create_blend_mode_property to not
    enumerate the #defines, but instead the string values
    - Uses fg.* instead of pixel.* and plane_alpha instead of plane.alpha
    Changes since v2:
    - Refines the comments of drm_plane_create_blend_mode_property:
    1) Puts the descriptions (after the ":") on a new line
    2) Adds explaining why @supported_modes need PREMUL as default
    Changes since v3:
    - Refines drm_plane_create_blend_mode_property(). drm_property_add_enum()
    can calculate the index itself just fine, so no point in having the
    caller pass it in.
    - Since the current DRM assumption is that alpha is premultiplied
    as default, define DRM_MODE_BLEND_PREMULTI as 0 will be better.
    - Refines some comments.
    Changes since v4:
    - Adds comments in drm_blend.h.
    - Removes setting default value in drm_plane_create_blend_mode_property()
    as it is already in __drm_atomic_helper_plane_reset().
    - Fixes to use state->pixel_blend_mode instead of using
    plane->state->pixel_blend_mode in reset function.
    - Rebases on drm-misc-next.

  • There are a lot of drivers that subclass drm_plane_state, all of them
    duplicate the code that links together the plane with plane_state.

    On top of that, drivers that enable core properties also have to
    duplicate the code for initializing the properties to their default
    values, which in all cases are the same as the defaults from core.

    Change since v1:
    - Make it consistent with the other helpers and require that both
    plane and state not be NULL, suggested by Boris Brezillon and
    Philipp Zabel.

  • Problems:
    - GPU hang when run Google Earth apk on 8MM EVK board
    - Android DEQP/SKQP CTS have random failures
    - Khronos ES20 CTS have random failures

    Analysis:
    GPU got stuck in shader module when process specific data format,
    this is caused by VSI GCNanoUltra Errata(HBN1286), which does not set
    the specific intermediate register to 0 in hardware reset sequence after power up,
    this wrong register will cause the unexpected result when process specific data type,
    wrong behavior will happen and may cause out of bound access in shader programming.

    Fix:
    GPU driver will submit the predefined command(dummy draw) with fake stream and shader,
    also set scissor with (0,0,0,0) to avoid draw out, no pixel output on hardware pipeline,
    this workaround can set the specific register to 0 as the effective SW remedy.

    Impact:
    No obvious functionality and performance impact with dummy draw workaround,
    it only takes several cycles in command fetch --> vertex shader --> primitive,
    and then cull out of reset of GPU pipelines.

    This patch can fix the same GPU problem for 7ULP.

  • The CRTC background should be full screen instead of partial
    screen, because the DRM core is likely to add configurable
    background color support in the future. We may cover the full
    screen with ConstFrame0/1, upon which builds planes. With this,
    it is easier to compute each plane's layer offset vs CRTC start
    point and all ConstFrame units can be controlled by CRTC.

  • In dpu_helper_funcs->atomic_begin(), we temporarily set the plane's
    ExtDst source to ConstFrame in shadow. In the plane driver,
    dpu_plane_helper_funcs->atomic_update() can update the shadow if
    necessary. This way, we may set the source as either ConstFrame
    or LayerBlend. We only set the source for the old top plane in
    ->atomic_begin(). However, in cases where pixel combiner is used,
    the top planes are tracked separately for the master stream and
    the slave stream with ->is_left_top or ->is_right_top flags
    instead of ->is_top flag when pixel combiner is not used. This
    patch corrects the source for the cases where pixel combiner is
    used.

  • The bit DIV0 of register STORE9_STATIC is used as a control bit
    to fix the unsynchronization issue bewteen two display streams
    in FrameGen side-by-side mode, which is introduced from an ECO
    operation for the display controller. The bit has to be one
    when the side-by-side mode is enabled. And, it has to be zero
    when the mode is disabled, otherwise, a single display stream
    cannot startup correctly. Since the DPU common driver initializes
    the register for us at the driver probe stage and system resume
    stage, we may remove the same initialization logic of our own.
    Without this patch, as the DPU blit engine DRM driver is resumed
    relatively late, the bit would be overwritten to be zero at the
    driver's ->resume() callback, which causes the display controller
    cannot be correctly resumed from FrameGen side-by-side mode and
    content ExtDst shadow load done event from the slave stream won't
    come.

    at driver probe stage and system resume stage at least. Since
    we have the DPU KMS driver and DPU blit engine DRM driver, the
    initialization needs to be done only in the DPU common driver
    so that the register won't be overwritten accidentally by the
    two drivers with each other. We see the overwriting issue at
    the system resume stage because the blit engine driver resumes
    relatively late and it initializes the register blindly by
    writing the bit to zero, thus the display controller cannot be
    resumed correctly in FrameGen side-by-side mode and content
    ExtDst shadow load done event from the slave stream won't come.

  • When GST receives V4L2_EVENT_SOURCE_CHANGE, it calls g_fmt ioctl and
    expects that the driver will report the pixel format.
    So far, the driver was unable to distinguish, by looking at the jpeg
    SOF marker, if an image is YUV444 or RGB24, both have 3 color components
    and no subsampling.
    Consider the colorspace is RGB if the transform flag from APP14 marker
    segment has the value 0, in mxc_jpeg_parse, if needed, update the pixel
    format from yuv444 to rgb24.

  • We don't need to notify the bus reset for class driver if the non-control
    endpoints are not enabled. It could cause unnecessary disconnect event for
    android due to below two reasons:
    - Android declares the disconnect event for reset handler.
    - The controller will get two reset interrupts at HS mode
    it fixed two below oops:
