drm-meson

[Neil Armstrong]

Hello !

Thanks for testing.

Can you provide me more details ?

Can you :
1) push the current linux source with the applied patches to a git tree (github for example) so I can test it
2) is the monitor an HDMI or a DVI monitor ? i.e. do you use a HDMI to DVI converter ?
3) Can you boot with the drm.debug=0x3f kernel parameter and send me the DRM logs ?

Thanks,
Neil

PS: like for Heiner, can you Cc the linux-amlogic list ? it could be beneficial for everyone ! And nothing is secret here.
linux-amlogic at lists.infradead.org
