Leu changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kle@bluewin.ch --- Comment #14 from C. Leu --- Hi all, as of 2025 here follows some additional information about the "clov= er" 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 most= ly 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 opt= ion on BSD. ;-) Note, this information is predominately GCN Radeon hardware and radeonsi dr= iver related. In contrast, older TeraScale Radeon hardware and the r600 Mesa dri= ver have additional problems most likely because of some TeraScale specific LLVM flaws. --=20 You are receiving this mail because: You are the assignee for the bug.=
