https://bugzilla.kernel.org/show_bug.cgi?id=201753 --- Comment #4 from Suravee Suthikulpanit (suravee.suthikulpanit@xxxxxxx) --- Created attachment 295089 --> https://bugzilla.kernel.org/attachment.cgi?id=295089&action=edit (RFCv2) Proposed workaround for the IOMMU PMC issue RFCv2 patch adds the logic to retry after 10msec wait for each retry loop. I have founded that certain platform takes about 10msec for the power gating to disable. Please give this a try to see if this works better on your platform.
