pub const CALL_FRAME_COST: u64 = 1024;Expand description
#3 call-frame base: the fixed per-CALL frame-setup cost (callee
address-space page table + dispatch table + frame push), independent of
code size. The code-size (compile) and read-only-page-in components are
added on top by call_frame_cost. Charged at an in-kernel CALL
(ecall.jar OP_HOST_CALL).
