hi,

1. I have compiled the kernel 3.10 and copy compiled mali_kbase.ko into /system/lib/modules.

2. And, copy below Midgard GPU User-Space Binary Drivers into /usr/lib.
mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz
mali-t76x_r6p0-02rel0_linux_1+fbdev.tar.gz

3. lsmod to check if the mali_kbase.ko have loaded as below
Module SizeUsed by
mali_kbase 2407970

4. make sure we have full permission to access:
/dev/mali0
/dev/fb*
mali_kbase.ko
Midgard GPU User-Space Binary Drivers

5. check the kernel space driver in kernel source (seems modified from TX011-SW-99002-r6p0-02rel0.tgz)

6. follow below thread to setup fb
http://bbs.t-firefly.com/forum.php?mod=viewthread&tid=321&highlight=driver
╭────
│ sudo -s
│ cat << EOF >/etc/init/fbset.conf
│ # fbset - run fbset to set truecolor fbmo
│ description "run fbset before lightdm"
│ start on startup and started udev or starting lightdm
│ task
│ script
│ [ -x /bin/fbset ] && /bin/fbset -a -nonstd 1 -depth 32 -rgba "8/0,8/8,8/16,8/24"
│ end script
│ EOF
│ cat << EOF >/etc/X11/xorg.conf
│ Section "Screen"
│ Identifier "Default Screen"
│ DefaultDepth 24
│ EndSection
│ EOF
╰────

But, it seems still not work:
firefly@firefly:~$ sudo clinfo
I: ICD loader reports no usable platforms

firefly@firefly:~$ sudo glmark2
** GLX does not support GLX_EXT_swap_control or GLX_MESA_swap_control!

So, any one can help to guide me to debug for this problem?
Thanks a lot.

试试这个固件 http://developer.t-firefly.com/thread-9233-1-1.html
opengles是ok的

hi isle,

thanks a lot for your information.
I have test with Firefly-rk3288_Ubuntu_1604_2016_08291523_Beta.img on reload board, and openCL/openGL ES both works well, except VGA i2c4 keep prompting in console to lag the system. (appended logs as below)

[ 1722.064489] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2
[ 1722.164485] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2
[ 1732.284885] rk3x-i2c ff160000.i2c: timeout, ipd: 0x80, state: 2

anyway, it works, thank you.

hi isle,

thanks a lot for your information.

您好，dalton.lai ，请教一下，请问新的固件，
是已经把 mali驱动都已经编译整合好了，我们只需要 apt-get install glmark2-es2 就可以测试 opengl了。

还是说我们必须自己按照文档操作一下，编译内核，编译模块，把 mali_kbase.ko 自己加进去才行。

您好 isle：

我在 rk3288_reload 板子上想要按照文档
http://bbs.t-firefly.com/forum.php?mod=viewthread&tid=321&extra=page%253D2
测试opengl。但是碰到一些问题，能不能指导一下，我是哪一步做错了。

1. 下载内核源码
git clone http://bitbucket.org/T-Firefly/firefly-rk3288-kernel.git
mv firefly-rk3288-kernel kernel重命名一下
cd kernel
git fetch origin lollipop:lollipop
git checkout lollipop

2. 先编译一遍
make firefly-rk3288-reload-linux_defconfig
make -j8 firefly-rk3288-reload-linux.img

3. 下载
firefly-mali-driver-TX011-SW-99002-r5p1-00rel0.tar
到跟kernel在同一级目录里
tar zxvf firefly-mali-driver-TX011-SW-99002-r5p1-00re10.tar
cd kernel
然后编辑arch/arm/configs/firefly-rk3288-reload-linux_defconfig (解压补丁包的时候，更新了 firefly-rk3288-linux_defconfig, 但是我用的是reload板子，所以看了一下 firefly-rk3288-linux_defconfig 的变化，然后修改 firefly-rk3288-reload-linux_defconfig, 不知道这样做是不是对的）
在 firefly-rk3288-reload-linux_defconfig 文件里：
尾部增加三行
CONFIG_DMA_SHARED_BUFFER_USES_KDS=y
CONFIG_KDS=y
CONFIG_MALI_PLATFORM_FAKE=y
中间也有一部分mali配置的，将
CONFIG_MALI400=m
# CONFIG_MALI400_PROFILING is not set
CONFIG_MALI_SHARED_INTERRUPTS=y
这三行全都屏蔽掉。就修改了这两处

4. 再次编译
make firefly-rk3288-reload-linux_defconfig
make -j8 firefly-rk3288-reload-linux.img

5. 编译modules
make modules
然后报错
报错1：找不到 arm_cstd.h , 我搜了一下打补丁之前的内核，有这个文件，于是将打补丁之前的drivers/gpu/arm/midgard/malisw/arm_cstd 目录都拷贝过来错误没有了
报错2：提示缺好几个mali_kbase_pm*.h，搜了一下打补丁之前的内核，有的都拷贝过来，错误没了
报错3：提示却 mali_kbase_device_internal.h找不到了，就不知道该怎么办了。

因为文档里边提供的补丁包，是更新了 firefly-rk3288-linux_defconfig ,但是我用的是reload板子，所以不太清楚哪些步骤需要调整，谢谢了。

hi isle,

thanks a lot for your information.

你好，dalton.lai，请问能详细说下怎样在ubuntu系统上配置opencl环境的流程吗
