Leu <[email protected]> --- Hi all, as of 2025 here follows some additional information about the "clover" topic and Linux. Regrading Mesa 25.0 and LLVM 19 clover seems to perform quite well in conjunction with a Radeon RX 580 GPU (mentioned by the OP) which is GCN4 hardware. https://gitlab.freedesktop.org/mesa/mesa/-/issues/12332#note_2712711 https://gitlab.freedesktop.org/mesa/mesa/-/issues/12404 However, it should be added that clover suffers regularly of breakages mostly because of new or removed LLVM features. This seems to be again the case for LLVM 20.x and 21.x. https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33805#note_2802600 Finally, clover is in general not operational on GCN5 and newer Radeon class hardware including the RDNA series. Most likely this is because of some not properly set-up stuff at the LLVM side. https://gitlab.freedesktop.org/mesa/mesa/-/issues/4189 So it is currently not possible to use clover at an Radeon RX5700XT graphics card. But there exist as an alternative rusticl which should be also an option on BSD. ;-) Note, this information is predominately GCN Radeon hardware and radeonsi driver related. In contrast, older TeraScale Radeon hardware and the r600 Mesa driver have additional problems most likely because of some TeraScale specific LLVM flaws. -- You are receiving this mail because: You are the assignee for the bug.
