Bug ID: 94917 Summary: radeonsi supports GL_ARB_shader_storage_buffer_object with 0 GL_MAX_COMBINED_SHADER_STORAGE_BLOCKS Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: jlegg@feralinteractive.com QA Contact: dri-devel@lists.freedesktop.org
Created attachment 122892 --> https://bugs.freedesktop.org/attachment.cgi?id=122892&action=edit Program which test for the issue
When mesa git fa46848e51a619aba5a748316fe8fe4c2e17d243 is built against LLVM 3.8.0, with a Radeon R9 270, support for the GL_ARB_shader_storage_buffer_object extension is claimed. However, GL_MAX_COMBINED_SHADER_STORAGE_BLOCKS is 0. The minimum required by the ARB_shader_storage_buffer_object specification is 8.
https://cgit.freedesktop.org/mesa/mesa/commit/?id=bfd11c599600960f966d5d217b... makes it look as if support was only intended for LLVM 3.9 or later.

--- Comment #1 from Nicolai Hähnle nhaehnle@gmail.com --- Hi James, thanks for the report. Probably some confusion in how the statetracker maps Gallium cap bits to extension support, I'm going to take a look.
