Open cl environment

Hi @thinkoco
Could you tell me how can create De1-SoC linux image with OpenCL driver and init_opencl_.sh file? I have spent a lot of time looking for any documents about it but i couldn't find anything!
Thanks you!

Hi， A: 1.You can downlaod the c5soc_opencl_lxde_fpga_reconfigurable_20201027.img 2. do as follows，and choose de1-soc in step 2 https://github.com/thinkoco/c5soc_opencl#run-default-opencl-application Now, the sdcard is for de1-Soc with de1-Soc sharedonly-vga BSP B: For building your own sdcard,here are some guides. https://github.com/thinkoco/c5soc_opencl/blob/master/documents/LinuxAndDrivers.md#how-to-update-opencl-driver https://github.com/thinkoco/c5soc_opencl/blob/master/documents/HowToBuildSDImage.md

hi @thinkoco,
I want to build my sdcard so i have tried to do your B option with socfpga-opencl_4.1.22 branch on your git. But when i use cp config_opencl .config , the system informs that no file such a config_opencl or .config file. I have clicked on show hidden file but there is no file named config_opencl or .config

Hi, the socfpga-3.18 is a stable branch for opencl.
Also, linux 4.9 and 4.19 has been tested with modified opencl driver.Here are some guides.

@thinkoco I'm following your guides: https://github.com/thinkoco/c5soc_opencl_rte/blob/master/documents/How_to_do.md with linux 4.9. But when I'd used command make zImage, i got this error

[thinkoco]

hi @18521613
have you check out the socfpga-4.9.78-aoc barnch ?

git clone --depth 3 --branch socfpga-4.9.78-aocl https://github.com/thinkoco/linux-socfpga.git
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
export LOADADDR=0x8000
make c5socl_defconfig
make zImage -j4
make modules
make socfpga_cyclone5_de10_nano.dtb

make zImage -j4
make modules
make socfpga_cyclone5_de10_nano.dtb

Yes, the last picture i sent to you that is socfpga-4.9.78-aocl branch and when i used make zImage -j4 i got the same error. And i have a question that do i have to do Update linux kernel part in your guide: https://github.com/thinkoco/c5soc_opencl_rte/blob/master/documents/How_to_do.md with socfpga-4.9.78-aocl branch
And one more when i try with linux 4.19 i also got this error:

[thinkoco]

@18521613
for linux 4.9, no need to update files after checkout the socfpga-4.9.78-aocl branch

git clone --depth 3 --branch socfpga-4.9.78-aocl https://github.com/thinkoco/linux-socfpga.git
export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
export LOADADDR=0x8000
make c5socl_defconfig
make zImage -j4
make modules
make socfpga_cyclone5_de10_nano.dtb

for linux 4.19, update the driver files , makefile and kconfig

Hi @thinkoco,
I have built my sd card image with opencl driver successfully. But when i try to execute hello_world example of BSP(Board Support Package) for Altera SDK OpenCL 18.1 from terasic (http://download.terasic.com/downloads/cd-rom/de1-soc/linux_BSP/OPENCL18.1/DE1-SoC_OpenCL_BSP.zip) i got this error:

Do you know the way to solve this error? Thanks you!

[thinkoco]

@18521613
maybe, the sdcard is unpluged when data copying. just fix it by fsck

Thanks for your help, I have solved that issue. But i got another issue :(. I have run init_opencl_18.1_4.19.sh but when i try to execute hello_world.aocx the system inform that Couldn't open /dev/ac10 device! Did you load the driver?

And when i run ls /dev there is no ac10 here! Do you know anything about this?

Thank you!

Hi, the opencl driver should be rebuild when running with a new zImage.

1. dowload the runtime enviroment files here.
   https://github.com/thinkoco/c5soc_opencl_rte/blob/master/linux-4.19.x/opencl_rte/aocl-rte-18.1.0-625.arm32.4.19.tar.xz
2. here is the guide for buiding opencl driver

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
cd  xxxxxx/aocl-rte-18.1.0-625.arm32.4.19/board/c5soc/arm32/driver
make KDIR=xxxxxx/linux-socfpga

Hi @thinkoco,
I have built opencl driver and copy it to /home/root in partiotion 2 of sdcard, but it not working..

[thinkoco]

Hi @18521613
you may change the path in the init_opencl_18.1_4.19 .sh for your case , or copy it to $AOCL_BOARD_PACKAGE_ROOT/arm32/driver/

#!/bin/bash
export INTELFPGAOCLSDKROOT=/root/aocl-rte-18.1.0-625.arm32.4.19
export AOCL_BOARD_PACKAGE_ROOT=$INTELFPGAOCLSDKROOT/board/c5soc
export PATH=$INTELFPGAOCLSDKROOT/bin:$PATH
export LD_LIBRARY_PATH=$INTELFPGAOCLSDKROOT/host/arm32/lib:$AOCL_BOARD_PACKAGE_ROOT/arm32/lib:$LD_LIBRARY_PATH
insmod $AOCL_BOARD_PACKAGE_ROOT/arm32/driver/aclsoc_drv.ko
#export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3

Hi @thinkoco,
i have tried to build OpenCL driver like this guide: https://github.com/thinkoco/c5soc_opencl/blob/master/documents/LinuxAndDrivers.md. I have downloaded Intel FPGA Runtime Environment for OpenCL Linux Cyclone V SoC TGZ 17.1 on Altera Download Website. And I build it for kernel 3.18 like your image: c5soc_opencl_lxde_fpga_reconfigurable_20201027.img. But when I try to test my OpenCL driver on your image. I got this error like this:

P/s: I've download kernel3.18 in your git: https://github.com/thinkoco/linux-socfpga/tree/socfpga-3.18

[18521613]

@thinkoco I'm following your guides: https://github.com/thinkoco/c5soc_opencl_rte/blob/master/documents/How_to_do.md with linux 4.9. But when I'd used command make zImage, i got this error

Hi @thinkoc,
I have built another image with linuxs-socfpga 4.9.78-ltsi so my zImage doesn't change fpga bridges name for aclsoc driver. I hope you could help me solve this error.
Thank you!!
