The problematic version are<o:p></o:p> around 3.15 and 3.16 which have commit f0a346b... but haven't commit c9224f... If it is the case,<o:p></o:p> you can apply c9224f... manually and rebuild the kernel or just disable the parse command by<o:p></o:p> invoke the following command (use Ubuntu as an example):<o:p></o:p> `# echo 0 > /sys/module/i915/parameters/enable_cmd_parser`<o:p></o:p> <o:p> </o:p> * Some unit test cases, maybe 20 to 30, fail on 4th Generation (HSW) platform.<o:p></o:p> The 4th Generation Intel Core Processors's support requires some Linux kernel<o:p></o:p> modification.
