           Summary: [regression, bisected] code re-factor causing games to
                    stutter or lock-up system
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

The following commit cause bad stuttering in the Batman Arkham City benchmark
(note when testing this game is 32bit). It also causes No Mans Sky to freeze my
system.

Link to No Mans Sky api trace below. Needs the following environment variables
set when running apitrace:

force_glsl_extensions_warn=true
allow_glsl_layout_qualifier_on_function_parameters=true

    radeonsi: factor si_query_buffer logic out of si_query_hw

    This is a move towards using composition instead of inheritance for
    different query types.

    This change weakens out-of-memory error reporting somewhat, though this
    should be acceptable since we didn't consistently report such errors in
    the first place.
