AM335x: DRM X11 Graphic support, Wayland support needed

Hi champs,

customer need support for DRM, X11.

Here is similar requirement list as customer need. https://e2e.ti.com/support/arm/sitara_arm/f/791/t/357868

Questions:

1. In http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide#Sample_usage it seems that X11 is not supported for AM335x.

Can you confirm ?

2. Is Wayland support offered  for AM335x?

3. Is there a possibility to activate HW acceleration on AM335 for Direct Rendering (in browser), HTML5 ?

    Hello Dirk,

    AM335x SDK does not support X11 and Wayland.

    About HW acceleration:

    The APIs that are accelerated with this hardware are,

    - OpenGL ES1.1

    - OpenGL ES2.0

    Note that OpenVG 1.1 is deprecated.

    In order to program and use the Graphics Engine, one of the above APIs need to be used. The APIs can be used to create standalone applications, but is typically used as a back-end to accelerate various higher level application frameworks like Android, Qt, Xorg. The enablers for these frameworks are described in more detail in next sections.

    Since the 3D accelerator (SGX core) is outside the ARM core, the Graphics drivers run on ARM core, and contain OS specific driver code to memory map the SGX core and program the engine from the OS running on the ARM core.

    New Features in AM335x and AM437x

    Changes specific for AM335x and AM437x, since Processor SDK 01.00.00 Release

    Graphics (SGX) Acceleration

    Graphics SDK is now obsolete. Graphics stack is integrated into Processor SDK.

    Supports null DRM based Full Window, with Front and Flip modes.

    Supports Qt5 acceleration with EGLFS

    For more details, see Graphics Migration

    Ethernet performance degraded ~10% on am335x-evm due to move from preempt_voluntary

    AM437x Dual-Camera demo enhancement to support single camera setup.

    Best regards,
