Re: [PATCH] drm/amdkfd: Drop IH ring overflow message to dbg

[Felix Kuehling]

Am 2022-02-18 um 17:01 schrieb Kent Russell:

When this was first implemented, overflows weren't expected in regular
operations, and tests weren't in place to cause said overflow. Now there
are cases where overflows occur with real workloads, but we know that
the kernel can handle this robustly, so move the message to a debug
message.
