OK, meson has fix from Koen and Neil. I'll send the fix for sun4i.
But rockchip and exynos need the help from Simon and Heiko because I
don't have a device.

this bugfix.

I find the reservation object will be created when: dma_buf_export
if no reservation object created when buffer object creation.
And the implicit fence can be synced before display in: drm_gem_fb_prepare_fb
but seems most display driver doesn't call this function.

Hi Eric and Wladimir,
GPU driver like VC4, Etnaviv and Lima only do rendering and left display
to other DRM display drivers. So there should be a render/display sync
problem for these drivers.
As I know, there are two ways: implicit and explicit described here:
