Hello people, I'm debugging a weird SIGILL issue in mariadb on my VisionFive 2 and would appreciate some help here - please see https://bugzilla.opensuse.org/show_bug.cgi?id=1219684#c1 My assessment so far: mariadb on the VisionFive2 crashes with a SIGILL on the "rdcycle" instruction. Looking at the RISC-V instruction set documentation this looks like a rather basic extension, which I ASSUME (!!) should be part of the architecture we build. Looking at the Upstream Integration plan of the JH7110 [1] however shows that the Timer patches are not yet upstreamed, so I concluded that the issue might arise from a yet incomplete kernel implementation. Would be great if someone with more insight could deny or confirm my suspicion. Thanks! Best, phoenix :-) [1] https://rvspace.org/en/project/JH7110_Upstream_Plan
