由于rotate硬件不支持crop，而exa加速中大部分都是crop操作，sunxi_arm_video中只是实现了参考代码（验证过功能），你们熟悉xorg硬件加速，更为详细的优化你们更为专业； | 由于rotate硬件不支持crop，而exa加速中大部分都是crop操作，sunxi_arm_video中只是实现了参考代码（验证过功能），你们熟悉xorg硬件加速，更为详细的优化你们更为专业； | ||

Mali-400 64-bit driver
Here is the good DRM powerpoint presentation by Free Electron: https://free-electrons.com/pub/conferences/2017/kr/ripard-drm/ripard-drm.pdf
Here is the DRM video presentation by Free Electron: https://www.youtube.com/watch?v=LbDOCJcDRoo
Wayland MALI Driver
- MALI-400 R6P2 Kernel Mode Setting binary download (1.86MB, MD5 523276872A9A11D1831ACE42F95DBBB1)
- MALI-400 R6P2 WAYLAND 64-bit binary driver and binary download (179KB, MD5 1698E8C54BDC6FE0804699F545FFE793)
X11 MALI Driver
- MALI EULA document
- MALI-400 64-bit binary driver and binary download from pine64.org (1.7MB, MD5 4F56AE6FB793E7D946867942AF58FEAC)
X11 Notice
Attached are the implemented driver and library.
- lib_x11_r6p0.tar.bz2：opengles upper layer library；
- r6p0_kernel_driver.tar.bz2：gpu driver code；
- sunxi_arm_video.tar.bz2： dri2 and exa video related accelerator implementation；
- sunxi_drm_0622.tar.bz2：drm driver；
Usage：
Using drm driver not able to coexist with display driver，due to utilize display relate BSP section；Drm driver able to integrate with sunxi_arm_video apply gem during cache and cache refresh，open cache able to increase performance；Drm driver utilize sunxi_tr BSP rotate section，not able to public sharing with sunxi_tr；
Known issue：
Due to rotate hardware not support crop, and majority exa accelerators operate using crop，sunxi_arm_video is reference code (features already verified)，this allow familiar with xorg hardware accelation， If using web page and character appear vertical strip, this may not related to cache problem and may due to character library. This issue still need to further verified.
