aocl install fails with compile error

Hi,

According to http://fpgasoftware.intel.com/requirements/19.3/, the Intel FPGA SDK for OpenCL is not supported in Ubuntu 18.04.

You are probably experiencing a conflict with the altera_cvp driver that is automatically installed with Ubuntu 16.04.

Can you try the link below:

https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/embedded/2018/why-does-aocl-diagnose-fail-to-find-device-on-ubuntu-16-04-5-lts.html

I would like to confirm with you that the kernel version used is 4.4.0-164?

If the problem still persist, please tell me as well.

Thanks

RE Ubuntu 18.04: I was hoping that it would be a simple fix to get that OS to support AOCL, but I guess not.

RE the compilation errors: I followed the support link but that addresses the issue with 'aocl diagnose'. I'm having a compile issue with the 'aocl install' command. I did run 'lspci -v | grep Altera' but found nothing. The kernel version is given in the compile output I posted above

Using kernel source files from  /lib/modules/4.4.0-164-generic/build
Building driver for BSP with name a10_ref
make: Entering directory '/usr/src/linux-headers-4.4.0-164-generic'

I looked in /usr/src/linux-headers-4.4.0-164-generic/include/linux/mm.h and, sure enough, the API does not match what I'm seeing in aclpci_cmd.c. The latter has an extra "1" argument where there should be a "struct page **". Here's a snippet from aclpci_cmd.c (after removing the preproc macros for clarity):

ret = get_user_pages(target_task, target_task->mm,
                        start_page + got * PAGE_SIZE,
                        num_pages - got, 1, 1,
                        p + got, vma);

while mm.h declares:

long get_user_pages(struct task_struct *tsk, struct mm_struct *mm,
                    unsigned long start, 
                    unsigned long nr_pages, unsigned int gup_flags, 
                    struct page **pages,
                    struct vm_area_struct **vmas);

I think there is a typo in the aclpci_cmd.c. After removing the second "1", the install completes successfully. Now I run 'aocl list-devices' and get:

$ aocl list-devices
--------------------------------------------------------------------
Warning:
No devices attached for package:
/home/okramer/intelFPGA_pro/19.3/hld/board/a10_ref
--------------------------------------------------------------------

I actually got to this point on Ubuntu 18.04 after fixing even more compile issues there.

Hi,

Regarding the problem as mentioned in the comment above, can you try to command "aocl flash"? I would like to know more information about this issue.

Thanks

aocl flash doesn't find any device attached. See above for output of "list-devices"

Hi,

You may be experiencing the problem I mentioned in my first comment. Please run through the procedure in this solution.

https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/embedded/2018/why-does-aocl-diagnose-fail-to-find-device-on-ubuntu-16-04-5-lts.html

If that doesn’t solve the problem, then please redo step 4 and 5 of the previous section in https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an807.pdf. Be sure not to power off.

Program the FPGA on your Intel® Arria® 10 GX FPGA Development Kit with the top.sof file by running the following command:

quartus_pgm -c 1 -m JTAG -o “p;top.sof”

Perform a soft reboot (sometimes called a warm reboot) of your host system. On Linux systems, use the /sbin/reboot command to perform a soft reboot.

After rebooting, run the diagnostic

$aocl diagnose

If that is successful, then continue to program the flash. If not, please power down the system and double check the jumpers.

Thanks

Hi,

I got customers who facing the same problem.

This problem might be due to the Ubuntu kernel version.

Can you try to revert back to Ubuntu with kernel version: 4.4.0-138 which is more stable version?

Thanks

I was able to successfully install with Ubuntu 16.04 kernel 4.15.0-72. A couple of points to possibly help others:

1. I had to continuously set the clock speed to 6M via jtagconfig, not just the one time as described in AN807. Everytime the board's power is cycled, the clock has to be reset to 6M.
2. aocl diagnose was failing the ICD tests but passing the BSP part. I found that the .icd files were not being copied to /etc/OpenCL/vendors by the install script, even though I was running as root with the aocl/quartus env set. After I manually copied $INTELFPGAOCLSDKROOT/icd/*.icd to /etc/OpenCL/vendors, the aocl diagnose ran successfully.

Hi,

Thanks you for your update and I am glad that you have successfully install the OpenCL SDK software.

Thanks
