Subject: drm/amdgpu: enlarge maximum waiting time of KIQ
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
KIQ in VF’s init delayed by another VF’s reset,
which would cause late_init failed occasionally.
MAX_KIQ_REG_TRY enlarged from 20 to 80 would fix this issue.
