Hi,
I was trying to figure out how we are supposed to manage synchronization
between a mode_set and a page_flip called on a crtc.
Say, if a mode_set is immediately followed by a page_flip. The driver
can't process the page_flip straight away since the hardware is still
completing the mode_set.
What is the driver supposed to do? Should it return -EBUSY? Or should it
somehow queue the page_flip task internally?
A lot of libdrm applications seem to call mode_set, and call a page_flip
soon after it. They tend to bail out if page_flip returns an error, they
don't try to do another page_flip if it fails the first time. Is this
okay behaviour?
Thanks,
Archit
