From: Krzysztof Helt Date: Thu, 24 Jul 2008 04:31:08 +0000 (-0700) Subject: tridentfb: add imageblit acceleration for Blade3D family X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0292be4a382957016e8b574dc292779cfb49e029;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git tridentfb: add imageblit acceleration for Blade3D family Add imageblit acceleration for the Blade3D family of cores. The code is based on code from the cyblafb driver. It is a step toward assimilating back the cyblafb driver into the tridentfb driver. The cyblafb driver handles a subfamily of the Trident Blade3d cores.
