Subject: [PATCH 5/6] Add DRM/KMS example support
|
||
|
|
|
||
|
|
Extend the main.c to support both legacy fbdev and DRM/KMS initialization.
|
||
|
|
|
||
|
|
To use legacy fbdev support, adjust lv_conf.h as follows:
|
||
|
|
LV_USE_LINUX_FBDEV=1
|
||
|
|
LV_USE_LINUX_DRM=0
|
||
|
|
|
||
|
|
To use DRM/KMS support, adjust lv_conf.h as follows:
|
||
|
|
LV_USE_LINUX_FBDEV=0
|
||
|
|
LV_USE_LINUX_DRM=1
|
||
|
|
|
||
|
|
Upstream-Status: Submitted [https://github.com/lvgl/lv_port_linux_frame_buffer/pull/47]
