I understand your concern. My patch will just check whether mst manager starts the probing process or not by confirming whether we sent LINK_ADDRESS to the 1st mst branch already. It will drop the CSN event only when the event comes earlier than the probing. The CSN events occur during topology probing should still have chance to be handled after probing process release the mgr->probe_lock I think. Does this make sense to you please? Thanks!
Yeah - that seems like the perfect solution :), sounds good to me
Thanks, Lyude! Could you help to merge drm changes - the [PATCH 1/3] and this one [PATCH 2/3] then please? The last one [PATCH 3/3], changes in amd only, I'll ping a gain for review. Appreciate : )
