Title: Re: Mali kernel driver TX011-SW-99002-r5p1-00rel0 for firefly


Test OpenGL ES Linux support on Firefly-RK3288 Development Board
════════════════════════════════════════════════════════════════

Introduction
────────────

Firefly-RK3288 development board is equipped with the powerful Mali
T764 GPU. Lately, ARM has released the binary user-space fbdev
driver. We, the Firefly team, have taken a first stab at it.

Environment:
- Firefly-RK3288 development board with latest dual boot firmware
installed.
- 64 bit Ubuntu Linux (12.04 or later) host pc.


Kernel
──────

First, we need to update the mali kernel driver.

Download Linux kernel driver TX041-SW-99002-r5p1-00rel0.tgz in
[http://malideveloper.arm.com/develop-for-mali/drivers/open-source-mali-t6xx-gpu-kernel-device-drivers/]

The porting process involves: replace the old driver files with new
ones, apply the kds patch, fix the compiling errors and update the
config file.

To make life easier, we've packaged all the files into
firefly-mali-driver-TX011-SW-99002-r5p1-00rel0.tar.gz .

╭────
│ cd /path/to/your/firefly/sdk
│ ls kernel  # kernel directory should be here
│ tar xzf /path/to/firefly-mali-driver-TX011-SW-99002-r5p1-00rel0.tar.gz
╰────

Then compile it:
╭────
│ cd kernel
│ make firefly-rk3288-linux_defconfig
│ make -j8 firefly-rk3288.img
│ make modules
╰────

The compiled mali module is located at drivers/gpu/arm/midgard/. Copy
mali_kbase.ko to your board:
╭────
│ scp drivers/gpu/arm/midgard/mali_kbase.ko root@BOARD_IP:/system/lib/modules/
╰────

(Why `/system/lib/modules/' ? Just because /etc/rc.local willl insmod
it automatically.)

Then follow the steps described in
[http://wiki.t-firefly.com/index.php/Firefly-RK3288/Build_kernel/en] ,
to pack zImage and initrd to linux-boot.img .

Flash linux-boot.img to recovery partition of the board.


User-space drivers
──────────────────

Download mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz in:
[http://malideveloper.arm.com/develop-for-mali/features/mali-t6xx-gpu-user-space-drivers/]

Then install it to the board:
╭────
│ cat /path/to/mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz \
│    | ssh root@BOARD_IP tar --strip-components=1 -xzf - -C /usr/lib
╰────


Compile Mali OpenGL ES SDK demos
────────────────────────────────

Download Mali_OpenGL_ES_SDK_v2.4.4.71fdbd_Linux_x64.tar.gz in
[http://malideveloper.arm.com/develop-for-mali/sdks/opengl-es-sdk-for-linux/]

Please choose Linux X64 archive.

To build the SDK demos, you need a cross compile toolchain. If you
have not installed yet, try this linaro toolchain:
[http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz]
(Extract it to /opt)

You also need to install cmake (sudo apt-get install cmake).

╭────
│ tar xzf /path/to/Mali_OpenGL_ES_SDK_v2.4.4.71fdbd_Linux_x64.tar.gz
│ cd Mali_OpenGL_ES_SDK_v2.4.4
│ mkdir build-arm
│ cd build-arm
│ export TOOLCHAIN_ROOT=/opt/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-
│ cmake -DTARGET=arm ..
│ make install
│ cd ..
│ # bin_arm contains all the result files
│ scp -r bin_arm root@BOARD_IP:/root
╰────


Set 32bit framebuffer
─────────────────────

Before running demos, the fbdev should be in 32 bit mode.

Run following commands on the board:
╭────
│ 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
╰────

Then reboot the device.


Run demos
─────────

Before running demos, make sure you have:
1. Flashed the new Linux kernel.
2. Updated mali_kbase.ko
3. Installed Mali user drivers
4. Uploaded Mali demos
5. Configured 32bit framebuffer

Then open a terminal, run one of the demo:
╭────
│ sudo -i
│ cd bin_arm/opengles_30/skybox
│ ./skybox
╰────

Enjoy!

Title: Re: Mali kernel driver TX011-SW-99002-r5p1-00rel0 for firefly
    Do the new kernel drivers work with the older userspace drivers, r5p0-06rel0 correctly?
    ARM mentioned in their forums, you need to use the exact same kernel driver version and userspace drivers otherwise things don't work.
    Maybe it works because only Mali T880 support was added and ARM didn't change other things.

    Userspace drivers step

1. cat /path/to/mali-t76x_r5p0-06rel0_linux_1+fbdev.tar.gz \
   
2. │    | ssh root@BOARD_IP tar --strip-components=1 -xf - -C /usr/lib

Copy the code

   
    Is it just copy zip content to /usr/lib?
    Maybe Firefly team can also try testing the following if possible.
    VLC, MPlayer video playback with GLES support/ in settings and see if videos play better.
    Maybe even build Kodi/XBMC with OpenGL GLES support and see if it can run in fullscreen.
    Video playback isn't going to be perfect because of VPU drivers, but maybe it's a little better.
Maybe X11 drivers are also needed, but ARM said only at end of March 2015, they are going to release, so long still.
    If it wasn't for Firefly, most RK3288 Rockchip users wouldn't even know how most things on their devices work and Linux support would be almost impossible

Title: Re: Mali kernel driver TX011-SW-99002-r5p1-00rel0 for firefly
I have success to compile the driver and test with the mali sdk demo.(r5p1 by busybee - with firefly board)

but some error is happen

1.when the screen is in  save power , when i press keyboard or click mouse ,the screen show abnormal.
  Sometimes I can see the normal desktop ,sometimes the board is auto reboot (most auto restart ).
  so , i think maybe it's a mali driver bug or the 32bit framebuffer bug?

Good stuff!

You mention its for stock kernel 3.6.10.  but the current firefly kernel is 3.10.0 right?


Will this work with 3.10.0?

You should run the demo with 32 bits framebuffer. And as Ava mentions, make sure you have permission on /dev/mali and /dev/fb0.

Try to run the demo in root user.

I want to share the img to you ,but i don't know how to pack my system for img.

I have look the wiki page:

http://wiki.t-firefly.com/index.php/Fir ... irmware/en

but it only metion how to mount a rootfs and modify some files, then pack the img.

the actuality is i should install some software  in rootfs .if you can share some method for package i'll share my rootfs.

or in another method ,i share my kernel.img and you could update the kernel ,then you should only do :

download: http://pan.baidu.com/s/1kT1MQpD

0.update the boot.img and resource.img

1.copy the mali user space driver *.so in /usr/lib
2.copy the example sdk application in rootfs
3.set the 32bit framebuffer

then you could test the framebuffer mali gpu test .

Do:

# lsmod


mali_kbase module should be listed.

And

# ls /dev/mali0

mali0 should be presented. If not, check the kernel log by:

# dmesg

So I thought I'd try to 'dd' some random data into the framebuffer:

1. 
   
2. # dd if=/dev/random of=/dev/fb0 bs=512 count=32
   
3. dd: writing '/dev/fb0': No such device
   
4. 0+1 records in
   
5. 0+0 records out
   
6. 0 bytes (0 B) copied, 0.000217584 s, 0.0 kB/s
   

Copy the code

The device node exists:

1. 
   
2. # ls -l /dev/fb*
   
3. crw-rw-rw- 1 root video 29, 0 Jan  1 12:00 /dev/fb0
   
4. crw-rw-rw- 1 root video 29, 1 Jan  1 12:00 /dev/fb1
   
5. crw-rw-rw- 1 root video 29, 2 Jan  1 12:00 /dev/fb2
   
6. crw-rw-rw- 1 root video 29, 3 Jan  1 12:00 /dev/fb3
   
7. crw-rw-rw- 1 root video 29, 4 Jan  1 12:00 /dev/fb4
   

Copy the code

But there seems to be some disconnect in the kernel between this device node and the backing driver.

I've also tried launch X with the fbdev driver, but I get a similar error:

Copy the code

The X log seems to think that the fb0 device has 0kB of video memory.  This might explain why the mmap fails for both weston and X.

Does anyone have any ideas why the stock kernel isn't working for me with the fbdev driver?

Thanks!

I would like to use the GPU hardware-accelerated in chrome browser( Ubuntu 14.0.4).
However, it does not seem to work.

Typing "chrome://gpu/" in Chrome, displays the following.
========================================================
Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Flash: Software only, hardware acceleration unavailable
Flash Stage3D: Software only, hardware acceleration unavailable
Flash Stage3D Baseline profile: Software only, hardware acceleration unavailable
Compositing: Software only, hardware acceleration unavailable
Multiple Raster Threads: Disabled
Rasterization: Software only, hardware acceleration unavailable
Threaded Rasterization: Unavailable
Video Decode: Software only, hardware acceleration unavailable
Video Encode: Software only, hardware acceleration unavailable
WebGL: Unavailable
=====================================================

I tried to get hardware acceleration in Chrome.

1.Search for "hardware" and tick the checkbox for "Use hardware acceleration..." in chrome://settings
2.Enable "Override software rendering list" in chrome://flags/

The result is the same as before.

Hello all,
as I see a lot of people have trouble with compiling the sources. There is an update of mali drivers. I think its would be perfect if developers could share the updated DualBoot image to flash. Or at least compiled stock kernel ready-to-use with instructions how to incorporate it into the clean system. Everybody would be happy to have working solution. Is it possible?

Would you like give me some suggestions?
Thanks!

I am about to purchase a Firefly Reload but I need to know if the current firmware supports GL ES fbdev drivers (NO X) with zero copy enabled. I see that there was some good progress on the original Firefly RK3288 board but I need to know if I will have good GL support on the Reload. It is a dealbreaker otherwise.
