Then this may be caused by another issue also documented in the README.md if you are using Linux kernel 3.15 or 3.16. If you also tried this, please let us know. Thanks. " * Almost all unit tests fail on Linux kernel 3.15/3.16. There is a known issue in some versions of linux kernel which enable register whitelist feature but miss some necessary registers which are required for beignet. The problematic version are around 3.15 and 3.16 which have commit f0a346b... but haven't commit c9224f... If it is the case, you can apply c9224f... manually and rebuild the kernel or just disable the parse command by invoke the following command (use Ubuntu as an example): `# echo 0 > /sys/module/i915/parameters/enable_cmd_parser` " > -----Original Message----- > From: Beignet [mailto:[email protected]] On Behalf Of > Julian Simioni > Sent: Tuesday, April 7, 2015 8:30 PM > To: Rebecca N.
