Hi,
we had posted this patch and we hope this patch is applied to libdrm
so that we can go ahead next work. as you may know, exynos drm driver
have already been merged to mainline.
please, let me know if there is any problem.
Thanks,
Inki Dae

> this patch adds libdrm_exynos helper layer that inclues some intefaces
> for exynos specific gem and virtual display driver and also adds exynos
> module name to modtest and vbltest.
>
> Changelog v2:
> - fixed exynos broken ioctl.
> the pointer of uint64_t *edid should be removed.
> - removed unnecessary definitions.
> - added drm prime interfaces.
> this feature is used to share a buffer between drivers or memory managers
> and for this, please, refer to below links:
