[Mesa-dev] [PATCH v2 4/5] i965: perf: add support for raw queries
Lionel Landwerlin
lionel.g.landwerlin at intel.com
Tue Apr 3 14:48:12 UTC 2018
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)
