Re: [PATCH v2 65/86] drm/amdgpu: Run DRM default client setup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On 8/21/24 09:00, Thomas Zimmermann wrote:
Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The amdgpu driver specifies a preferred color mode depending on
the available video memory, with a default of 32. Adapt this for
the new client interface.

v2:
- style changes
