rkhan467 84cb8538cd mesa: querying dma_buf modifiers for specific formats 
mesa wl_drm protocol is the backend for wayland server side which requires
the dmabuf modifiers for some DRM formats on specific devices like RPI.
Currently there is no support of giving any dmabuf modifiers on wl_drm protocol.
This dma_buf modifiers allows EGL implementations to add extra attributes
to drm_fourcc format.

Yocto BSP layer for the Raspberry Pi boards - http://www.raspberrypi.org/.

Description

This is the general hardware specific BSP overlay for the RaspberryPi device.

More information can be found at: http://www.raspberrypi.org/ (Official Site)

The core BSP part of meta-raspberrypi should work with different OpenEmbedded/Yocto distributions and layer stacks, such as:

  • Distro-less (only with OE-Core).
  • Angstrom.
  • Yocto/Poky (main focus of testing).

Dependencies

This layer depends on:

  • URI: git://git.yoctoproject.org/poky

    • branch: master
    • revision: HEAD

  • URI: git://git.openembedded.org/meta-openembedded

    • layers: meta-oe, meta-multimedia, meta-networking, meta-python
    • branch: master
    • revision: HEAD

Quick Start

  1. source poky/oe-init-build-env rpi-build
  2. Add this layer to bblayers.conf and the dependencies above
  3. Set MACHINE in local.conf to one of the supported boards
  4. bitbake core-image-base
  5. dd to a SD card the generated sdimg file (use xzcat if rpi-sdimg.xz is used)
  6. Boot your RPI.

Quick Start with kas

  1. Install kas build tool from PyPi (sudo pip3 install kas)
  2. kas build meta-raspberrypi/kas-poky-rpi.yml
  3. dd to a SD card the generated sdimg file (use xzcat if rpi-sdimg.xz is used)
  4. Boot your RPI.

To adjust the build configuration with specific options (I2C, SPI, ...), simply add a section as follows:

local_conf_header:
  rpi-specific: |
    ENABLE_I2C = "1"
    RPI_EXTRA_CONFIG = "dtoverlay=pi3-disable-bt"

To configure the machine, you have to update the machine variable. And the same for the distro.
