Subject: [PATCH 1/2] wayland: Switch to custom timer tick
|
|
|
|
The OE LVGL is configured to obtain timer tick from system timer
|
|
instead of using ad-hoc mechanisms to emulate timer tick using
|
|
threads or such. Use system timer to provide the tick.
|
|
|
|
The tick handling implementation comes from:
|
|
https://github.com/lvgl/lv_port_linux_frame_buffer.git
|
|
as of commit adf2c4490e17a1b9ec1902cc412a24b3b8235c8e
|
