The INTEL_performance_query extension provides a list of queries that a user can select to monitor a particular workload. Each query reports different sets of counters (roughly looking at different parts of the hardware, i.e. caches/fixed functions/etc...). Each query has an associated configuration that we need to program into the hardware before using the query. Up to now, we provided predefined queries. This change allows the user to build its own query (and associated configuration) externally, and have the i965 driver use that configuration through a new query named : Intel_Raw_Hardware_Counters_Set_0_Query When this query is selected, the i965 driver will report raw counters deltas (meaning their values need to be interpreted by the user, as opposed to existing queries that provide human readable values). This change is also useful for debug purposes for building new pre-defined queries and verifying the underlying numbers make sense before writing equations for user readable output. This change's purpose is also to enable GPA. GPA uses a library called MDAPI that processes raw counter data. MDAPI expects raw data to have a certain layout (per generation which is a bit unfortunate...). This change also embeds the expected data layouts. v2: Enable raw queries on gen 7->11, v1 had 7->9 (Lionel) v3: Don't assert on cherryview for gen7...
