[PATCH][VTD][QUIRK] added quirks for Sandybridge errata workaround, WLAN, VT-d fault escalation |
> Wouldn't that result in excessive lock holding time?
It would be a problem for older platforms like Weybridge but Sandybridge has
fixed the IGD IOTLB invalidation times. Although I have not done actual
measurement on this yet.
Given this quirks is for a corner case power management issue (not easily
duplicated), I will submit a patch to disable it by default until we can answer
you about the uses of the MMIO registers and implement the locking mechanism
properly.
