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)
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；
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；
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.
