OpenCL + Cyclone V SoC

Hi all again

I have managed to make /dev/acl to pop up. I thought the driver created it dynamically (alloc_chrdev_region->class_create->device_create) but aclsoc_load script showed me I was wrong. After "mknodding" the entry /dev/acl was ready. Then I run "user" program and it segfaults during mmap test.

This is "user" program output

...

Opened the device: file handle# 3!

And dmesg output...

By the way. Driver can be successfully loaded (no IRQ problems) if you change IRQ from 72 to another number (I tried 70 and it worked)
