Hi, Jens,
blk_mq_update_queue_map does this:
for_each_possible_cpu(i) {
if (!cpu_online(i)) {
map[i] = 0;
continue;
}
...
first_sibling = get_first_sibling(i);
if (first_sibling == i) {
map[i] = cpu_to_queue_index(nr_uniq_cpus, nr_queues,
queue);
queue++;
} else
map[i] = map[first_sibling];
This assumes that the first_sibling is listed before any other siblings,
which I don't believe is true. I don't think you get any guaranteed
ordering in that cpu_possible_mask.
... or did I miss something?
Cheers,
Jeff
