Bug ID: 107912 Summary: Please add support for PIPE_CAP_TGSI_MUL_ZERO_WINS to radeonsi Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: enhancement Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: davyaxel0@gmail.com QA Contact: dri-devel@lists.freedesktop.org
PIPE_CAP_TGSI_MUL_ZERO_WINS is a cap currently supported by nv50, nvc0 and r600, which means that TGSI_PROPERTY_MUL_ZERO_WINS is supported.
When enabled, the affected shaders have the behaviour 0*anything = 0 (including inside a mad). It is used by gallium nine when available.
All GCN cards support special legacy instructions to handle the behaviour.
Since opengl compat used to be a thing "we will never support because lack of time" and is now implemented, I thought maybe this MUL_ZERO_WINS may get added to the new radeonsi TODO list.
