[Mesa-stable] i915: Enable EGL_KHR_{fence,wait}_sync

Thu Jul 14 03:33:14 UTC 2016

Sending patches to implement DRI2_Fence extension for i915,
to enable EGL_KHR_fence_sync and EGL_KHR_wait_sync.

It is the step-by-step porting to i915 of i965/sync,
plus patch to support {server,client}_wait_sync without bound context.

[PATCH 1/3] i915/sync: Replace prefix 'intel_sync' -> 'intel_gl_sync'
[PATCH 2/3] i915/sync: Implement DRI2_Fence extension
[PATCH 3/3] i915: store reference to the context within struct

Motivation is to support (web)chromium which requires EGL_KHR_{fence,wait}_sync
Tested with marshmallow-x86 build on Asus Eee PC 1015PEM
