--------------------
While most operations use only the standard DRM modesetting interfaces, certain operations
unavoidably rely on specific driver behaviour (including dumb buffer allocation flags and cursor
plane z-ordering). As such, the armsoc driver must be configured for a particular DRM driver.
plane z-ordering). As such, the armsoc driver should choose a particular DRM driver dynamically
according to the current environment.
The currently supported DRM drivers are:
- pl111
- exynos
To configure armsoc for one of these, pass the --with-drmmode option to ./configure. For example:
$ ./configure --with-drmmode=pl111
- kirin
For other drivers, you will need to implement this support yourself. A template implementation is
provided in src/drmmode_template which can be built by passing --with-drmmode=template to ./configure.
provided in src/drmmode_template.
The interface is defined and documented in src/drmmode_driver.h, and you should refer to this while
modifying the template to set up your DRM driver's abstraction appropriately.
You can also copy src/drmmode_template into src/drmmode_<yourdrivername> and build with:
$ ./configure --with-drmmode=<yourdrivername>
You can also copy src/drmmode_template into src/drmmode_<yourdrivername>,
modify the driver_name to match with the name used in the kernel drm driver.
