Previously it was disabled right before translation was enabled. This way the disable logic is still executed even when translation is not be activated, e.g. with hw.iommu.dma=0 tunable set. On some platforms we need to disable PMR in order for core dump to work. At the same time it was observed that enabling translation has a significant impact on network performance. With this patch PMR can be disabled, with IOMMU translation not being turned on by appending the following to the loader.conf: hw.dmar.enable=1 hw.dmar.pmr.disable=1 hw.dmar.dma=0 Sponsored by: Stormshield Obtained from: Semihalf Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D34907 |
