There's nothing Linux can do for today's Hyper-V passthrough wrt to automatically turning on discard on my SATA SSD. Martin explained that vendors often disable UNMAP/WRITE SAME to DSM TRIM translation on purpose and/or have explicit device whitelists/blacklists for those devices they want to support. It could be that Microsoft are doing something similar (although it might be interesting to know how a Windows 2012 guest on Hyper-V handles things). -- Sitsofe | http://sucs.org/~sits/ _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
