lib/i915: add gem_engine_topology library and for_each loop definition

2019-05-12T22:58:57+00:00

The gem_engine_topology library is a set of functions that interface with the query and getparam/setparam ioctls. The library's access point is the 'intel_init_engine_list()' function that, everytime is called, generates the list of active engines and returns them in a 'struct intel_engine_data'. The structure contains only the engines that are actively present in the GPU. The function can work in both the cases that the query and getparam ioctls are implemented or not by the running kernel. In case they are implemented, a query is made to the driver to fetch the list of active engines. In case they are not implemented, the list is taken from the 'intel_execution_engines2' array and stored only after checking their presence. The gem_engine_topology library provides some iteration helpers: - intel_get_current_engine(): provides the current engine in the iteration. - intel_get_current_physical_engine(): provides the current physical engine, if the current engine is a virtual engine, it moves forward until it finds a physical engine. - intel_next_engine() it just increments the counter so that it points to the next engine. Extend the 'for_each_engine_class_instance' so that it can loop using the new 'intel_init_engine_list()' and rename it to 'for_each_context_engine'. Move '__for_each_engine_class_instance' to gem_engine_topology.h and rename it to '__for_each_static_engine'. Update accordingly tests/perf_pmu.c to use correctly the new for_each loops.

lib: ioctl_wrappers: reach engines by index as well

2019-04-05T07:58:58+00:00

With the new engine query method engines are reachable through an index and context they are combined with. The 'gem_has_ring()' becomes 'gem_context_has_engine()' that requires the index that the engine is mapped within the driver. The function has been moved from lib/ioctl_wappers to lib/i915/gem_context where it is more appropriate. The previous 'gem_has_ring()' function becomes a wrapper to the new 'gem_context_has_engine()'. Signed-off-by: Andi Shyti Reviewed-by: Chris Wilson Reviewed-by: Tvrtko Ursulin

lib/i915: Improve gem_context error messages

2019-03-26T10:38:07+00:00

Avoid embedding the DRM_IOCTL() macro into the error message as it is unreadable, and instead always wrap the ioctl with a self-descriptive helper. Signed-off-by: Chris Wilson Reviewed-by: Tvrtko Ursulin

lib/i915: Pretty print HW semaphores

lib/i915: Move mmap IOCTLs wrappers into separate file

2019-02-26T18:05:17+00:00

Move all mmap flavours and support function to separate file in i915 folder. This helps with moving i915 specific functions away from common libraries. v2: - Autotools still exists. (Petri) - Include gem_mman.h directly. (Chris) v3: - Keep includes explicit. (Chris) Signed-off-by: Antonio Argenziano Cc: Chris Wilson Cc: Petri Latvala Reviewed-by: Chris Wilson

tests/gem_media_vme: Simple test to exercise the VME block
