+Subject: [PATCH] RISC-V: use RDTIME for cycle timer and disable __builtin_readcyclecounter
+
+This commit backports and extends the fixes from MariaDB/server PRs #1981
+and #2980 to address the RISC-V RDCYCLE privileged instruction issue.
+
+Key changes:
+1. Use RDTIME instead of RDCYCLE for cycle timer on RISC-V
+2. Disable __builtin_readcyclecounter() for RISC-V as LLVM generates RDCYCLE
+
+Starting with Linux 6.6 [1], RDCYCLE is a privileged instruction on RISC-V and can't be used directly from userland.
+There is a sysctl option to change that as a transition period, but it will eventually disappear.
+
+Use RDTIME instead, which while less accurate has the advantage of being synchronized between CPU (and thus monotonic)
+and of constant frequency.
