From 31abfd2d350efe59fe3ecd283807402c6695b15a Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 8 May 2017 23:41:31 -0700 Subject: i965: Disable ARB_pipeline_statistics_query on Gen4-5. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We apparently enabled this on all platforms in Mesa 10.6. However, it was only ever implemented for Gen6+. The Gen4-5 query code goes up in flames with an "Unrecognized query target" unreachable() error if you even attempt to use any of the new functionality. This wasn't caught because the Piglit tests require OpenGL 3.0, which Gen4-5 cannot support. The extension spec does say 3.0 is required, though I'm not sure why - it seems like 2.1 would work fine. We could implement it anyway, but it's a little bit of a pain due to the lack of hardware contexts (so we have to snapshot around batches). Given that it's been 100% broken for two years and I haven't seen a bug report about it, I'm not terribly inclined to care. So, let it go.
