Re: [PATCH libdrm] exynos: add exynos drm support

Please, give me any comments and I hope this patch would be applied to libdrm if there is any problem.

Thanks, Inki Dae.

2012년 4월 2일 오후 9:08, Inki Dae inki.dae@samsung.com님의 말:

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.

this patch is based on a link below: git://anongit.freedesktop.org/mesa/drm commit id: e057a56448e2e785f74bc13dbd6ead8572ebed91
