How to enable Opencl support on hikey960?


#41

Thanks a lot! :smile:


#42

Thank you for share,I am flashed this Image and connected network via wifi,I config the file wpa_supplicant-wlan0.conf similar as following:
network={
ssid=“HUAWEI-FU8FLWy"
psk=”********"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
group=CCMP TKIP
pairwise=CCMP TKIP
priority=5
}

Wired connection not work yet on my hikey960


#43

@flowas does opencl works when you flash debian?


#44

I do not know how to check whether OpenCl works,can you tell me?


#45

I have OpenCL working on that image.

daedalean_defconfig should work for you. defconfig does not have mali
support enabled.

I flashed the debian9 image. It boots up perfectly. It says clinfo bash command not found. Also could you tell how to connect to the wifi as the network manager isn’t working. I tried to connect with wpa-supplicant.conf and even tried editing etc/network/interface but it didn’t work. Do I need to install clinfo or have you already added it.


#49
  1. apt install clinfo will install it if it isn’t there.
  2. To configure wifi edit /etc/wpa_supplicant/wpa_supplicant-wlan0.conf and
    reboot.

I believe I mentioned in my post with the links to the image how to
configure wifi.


#51

@bvermeul, can you share instructions on how to build the Linux image with the drivers? I’d like to be able to build my own with some modifications to the Linux image. Thanks!


#52

have you actually tried to run an opencl application? I can get clinfo to work on an unpatched kernel as well
but I am unable to run an opencl application on your kernel

Hey,

I need help in copying userspace ( .so.1 ) file.

Can you tell me where should i copy this file in ROOT FILE SYSTEM of Ubuntu.

Currently i am trying to enable gpu drivers on hikey 960.

Earlier i tried to copy .so.1 files in
/lib/aarch64-linux-gnu/

but it doesnt works!


#54

You need to copy them to /usr/lib/aarch64-linux-gnu/
You also need to create a mali.icd in /etc/OpenCL/vendors containing
"libmali.so" to make sure the OpenCL icd loader can find it correctly.

Run ldconfig afterwards.

I have created a rudimentary and incomplete script to create the root filesystems I use.
It is still missing some things (it doesn’t set up /boot, and doesn’t copy kernel/modules), but may still be usefull for someone. Any patches/comments are welcome.

The repository is located on github.


#56

Hey, I have some problems getting opencl to work. I’ve used some parts of bvermeuls script and his defconfig, but i if i run clinfo i get this error:

clinfo: /usr/lib/aarch64-linux-gnu/libOpenCL.so.1: version `OPENCL_1.0’ not found (required by clinfo)

Has anyone ever had this problem?


#58

Hello @Aegir
Can u share how did u flash debian on hikey960.
I tried with https://github.com/96boards/documentation/blob/master/consumer/hikey960/installation/linux-fastboot.md and https://github.com/96boards/documentation/blob/master/consumer/hikey/installation/linux-fastboot.md.
second link work successfuly untill flashing rootfs.
however, problem is hikey does not boot in normal mode.


#59

Installation

  1. Download from http://snapshots.linaro.org/reference-platform/embedded/morty/hikey960/latest/rpb/
    a boot*.img
    a rpb*-image-*hikey960-*.rootfs.img.gz
    bootloader/

  2. On the board: Set the dip-switches to 1 & 2 on, 3 off.
    Make sure fastboot is installed (sudo apt install fastboot if it is not).
    Connect a USB-C to USB-A cable to the laptop + board.
    Check what serial port got added (/dev/ttyUSB?)
    Execute the following commands to bootloader into RAM:
    $ chmod +x hikey_idt
    $ sudo ./hikey_idt -c config -p /dev/ttyUSB?
    You will see some output loading the fastboot bootloader into RAM.

  3. Execute the following commands to flash the bootloader:
    $ sudo fastboot flash ptable prm_ptable.img
    $ sudo fastboot flash xloader sec_xloader.img
    $ sudo fastboot flash fastboot l-loader.bin
    $ sudo fastboot flash fip fip.bin
    If for some reason fastboot doesn’t want to start (it did for me after flashing the bootloader once), set the dip-switches to 1 & 3 on, 2 off, and reset the board’s power supply.

  4. Unzip the rpb-*.img.gz file
    Execute the following commands to flash kernel/rootfs:
    $ sudo fastboot flash boot boot*.img
    $ sudo fastboot flash system rpb-*image*hikey960*.rootfs.img or the debian rootfs image.
    This last command takes about half an hour on USB2 and a few minutes on USB3, so take your time … or a USB3 cable.

  5. Set the dip-switches to 1 on, 2 & 3 off, and reset the board to boot into linux.

Hey baynaa,
bvermeuls answer should help you. I followed the instructions posted here: https://wiki.debian.org/InstallingDebianOn/96Boards/HiKey960 and build my own kernel with the config from bvermeul.


#61

Does the latest RPB image contain package management system like APT???


#62

Not that i know of, but as he suggests:

$ sudo fastboot flash system rpb-imagehikey960*.rootfs.img or the debian rootfs image.

So you can use the debian image from bvermeul or the debian image for the “normal” hikey. But in the latter case you should use a different kernel because otherwise the usb ports won’t work.


#63

No, it does not. That’s why step 4 says to use the rpb image, or the debian rootfs image from one of my previous posts.
