Public bug reported: [Impact]
Mesa 10.1.x doesn't enable support for CHV/BSW, like it didn't for Broadwell. Enabling it needs five commits backported from 10.2: 70285f607ce2a06 i965: initialize more device info fields for Cherryview 9b6b084eb7b10d0 i965: Add Cherryview support. 850e372fc7ff337 i965: Drop bogus F32TO16/F16TO32 instructions on Broadwell - use MOV. a5e54c91a3b7355 i965: Store absolute thread count in max_wm_threads on Broadwell. dca84b4b5b23b68 i965: Use MOV, not OR for setting URB write channel enables on Gen8+. [Test Case] install trusty on a BSW machine, unity falls back to software rendering which is slow. [Regression potential] Slim, since it enables new HW, and though some commits are shared with BDW (they are both gen8) they are bugfixes. ** Affects: mesa (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1404217 Title: Backport support for Cherryview/Braswell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1404217/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
