Pooled EU is a BXT only feature, prep patches are merged a while ago. Patch that enables the feature is also reviewed but not merged because of lack of opensource user. https://lists.freedesktop.org/archives/intel-gfx/2015-July/072051.html Kernel simply enables the support, userspace enquires certain parameters from kernel and dispatches threads to use this feature. One of the patch is a WA related to this feature, this only affects 2x6 devices, please check the patch for more details. Beignet recently expressed interest in using feature and asked to complete kernel support, they are currently adding userspace and libdrm support, meanwhile we can get some testing done on these patches.
