From 7e2c6147da427df974b673178d7142836bfac6a1 Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin Date: Wed, 14 Mar 2018 13:15:12 +0000 Subject: intel: devinfo: store number of EUs per subslice This will be reused to store values reported by the kernel. The main use case will be for use as the input values of the metric sets equations for the INTEL_performance_queries extension. By storing this information in the gen_device_info we make this non GL specific so this can be reused by Vulkan if we ever have an equivalent extension.
