Series | numa: clarify error message when node index is out of range in -numa dist, ... | expand |
Pretty long patch summary line. Do we not try to limit that?

diff --git a/numa.c b/numa.c index a3637cc..dedc149 100644 --- a/numa.c +++ b/numa.c @@ -142,8 +142,8 @@ static void parse_numa_distance(NumaDistOptions *dist, Error **errp) if (src >= MAX_NODES || dst >= MAX_NODES) { error_setg(errp, - "Invalid node %d, max possible could be %d", - MAX(src, dst), MAX_NODES); + "Invalid node %d, should be in range [0 - %d]", + MAX(src, dst), MAX_NODES - 1); return; }
When using following CLI: -numa dist,src=128,dst=1,val=20 user getsi a rather confusing error message: "Invalid node 128, max possible could be 128" Where 128 is number of nodes that QEMU supports (MAX_NODES), while src/dst is an index up to that limit, so it should be MAX_NODES - 1 in error message. Make error message to explicitly state valid range for node index to be more clear.
