From: Jerome Glisse Date: Tue, 24 Jul 2012 19:05:43 +0000 (-0400) Subject: r600g: enable streamout only on 2.14 or latter kernel X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1ffac44e83a6fa6f486c6493e1d4eda259938ebb;p=mesa.git r600g: enable streamout only on 2.14 or latter kernel The kernel streamout support was supposed to get into 3.3 along the tiling change and thus use the same kernel version bump of 2.13 to report userspace that streamout register were supported. This is not what happen. So as streamout kernel support did not bump the kernel driver version, rely on kernel 2.14 version bump to know if streamout is enabled or not. Which means you need at least 3.4 kernel.
