Amlogic Meson Display Controller
================================
The Amlogic Meson Display controller is composed of several components
that are going to be documented below:
DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
| vd1 _______ _____________ _________________ | |
D |-------| |----| | | | | HDMI PLL |
D | vd2 | VIU | | Video Post | | Video Encoders |<---|-----VCLK |
R |-------| |----| Processing | | | | |
| osd2 | | | |---| Enci ----------|----|-----VDAC------|
R |-------| CSC |----| Scalers | | Encp ----------|----|----HDMI-TX----|
A | osd1 | | | Blenders | | Encl ----------|----|---------------|
M |-------|______|----|____________| |________________| | |
___|__________________________________________________________|_______________|
VIU: Video Input Unit
---------------------
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
This part is also in charge of the CSC (Colorspace Conversion).
It can handle 2 OSD Planes and 2 Video Planes.
VPP: Video Post Processing
--------------------------
The Video Post Processing is in charge of the scaling and blending of the
various planes into a single pixel stream.
There is a special "pre-blending" used by the video planes with a dedicated
scaler and a "post-blending" to merge with the OSD Planes.
The OSD planes also have a dedicated scaler for one of the OSD.
VENC: Video Encoders
--------------------
The VENC is composed of the multiple pixel encoders :
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- ENCP : Progressive Video Encoder for HDMI
- ENCL : LCD LVDS Encoder
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
tree and provides the scanout clock to the VPP and VIU.
The ENCI is connected to a single VDAC for Composite Output.
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
Device Tree Bindings:
---------------------
VPU: Video Processing Unit
--------------------------
Required properties:
- compatible: value should be different for each SoC family as :
- GXBB (S905) : "amlogic,meson-gxbb-vpu"
- GXL (S905X, S905D) : "amlogic,meson-gxl-vpu"
- GXM (S912) : "amlogic,meson-gxm-vpu"
followed by the common "amlogic,meson-gx-vpu"
- reg: base address and size of he following memory-mapped regions :
- vpu
- hhi
- dmc
- reg-names: should contain the names of the previous memory regions
- interrupts: should contain the VENC Vsync interrupt number
Required nodes:
The connections to the VPU output video ports are modeled using the OF graph
bindings specified in Documentation/devicetree/bindings/graph.txt.
The following table lists for each supported model the port number
corresponding to each VPU output.
Port 0 Port 1
-----------------------------------------
S905 (GXBB) CVBS VDAC HDMI-TX
S905X (GXL) CVBS VDAC HDMI-TX
S905D (GXL) CVBS VDAC HDMI-TX
S912 (GXM) CVBS VDAC HDMI-TX
Example:
tv-connector {
compatible = "composite-video-connector";
port {
tv_connector_in: endpoint {
remote-endpoint = <&cvbs_vdac_out>;
};
};
};
vpu: vpu@d0100000 {

Dumb Buffer Objects
===================
The KMS API doesn't standardize backing storage object creation and
leaves it to driver-specific ioctls. Furthermore actually creating a
buffer object even for GEM-based drivers is done through a
driver-specific ioctl - GEM only has a common userspace interface for
sharing and destroying objects. While not an issue for full-fledged
graphics stacks that include device-specific userspace components (in
libdrm for instance), this limit makes DRM-based early boot graphics
unnecessarily complex.
Dumb objects partly alleviate the problem by providing a standard API to
create dumb buffers suitable for scanout, which can then be used to
create KMS frame buffers.
To support dumb objects drivers must implement the dumb_create,
dumb_destroy and dumb_map_offset operations.
- int (\*dumb_create)(struct drm_file \*file_priv, struct
drm_device \*dev, struct drm_mode_create_dumb \*args);
The dumb_create operation creates a driver object (GEM or TTM
handle) suitable for scanout based on the width, height and depth
from the struct :c:type:`struct drm_mode_create_dumb
<drm_mode_create_dumb>` argument. It fills the argument's
handle, pitch and size fields with a handle for the newly created
object and its line pitch and size in bytes.
- int (\*dumb_destroy)(struct drm_file \*file_priv, struct
drm_device \*dev, uint32_t handle);
The dumb_destroy operation destroys a dumb object created by
dumb_create.
- int (\*dumb_map_offset)(struct drm_file \*file_priv, struct
drm_device \*dev, uint32_t handle, uint64_t \*offset);
The dumb_map_offset operation associates an mmap fake offset with
the object given by the handle and returns it. Drivers must use the
:c:func:`drm_gem_create_mmap_offset()` function to associate
the fake offset as described in ?.
Note that dumb objects may not be used for gpu acceleration, as has been
attempted on some ARM embedded platforms. Such drivers really must have
a hardware-specific ioctl to allocate suitable buffer objects.
