After mesa switched build system to meson, the logic to generate dri related artifacts changed too, which means when no dri backend is enabled then dri drivers and corresponding headers dont get generated and hence we end up with missing pkgconfig files e.g. dri.pc which usually will come from full mesa3d package, but in rpi when userland is used we only build GL pieces of mesa. This patch therefore enables swrast dri backend when using userland, which gives us the needed header and .pc files to build packages like Xorg server, since EGL driver will come from userland, the dri backend would be unused and hence should not be effective at runtime. Addresses issue report with https://github.com/agherzan/meta-raspberrypi/pull/773 there is no need to check for graphics stack since mesa-gl is only used with userland graphics Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Trevor Woerner <twoerner@gmail.com> |

meta-raspberrypi
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).
- Yoe Disto (Video and Camera Products).
- 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
- source poky/oe-init-build-env rpi-build
- Add this layer to bblayers.conf and the dependencies above
- Set MACHINE in local.conf to one of the supported boards
- bitbake core-image-base
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- Boot your RPI
Quick Start with kas
- Install kas build tool from PyPi (sudo pip3 install kas)
- kas build meta-raspberrypi/kas-poky-rpi.yml
- Use bmaptool to copy the generated .wic.bz2 file to the SD card
- 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.
