I would like to deprecate this command line and ask users to use iommu.strict instead.
--- a/drivers/iommu/intel/iommu.c +++ b/drivers/iommu/intel/iommu.c @@ -436,7 +436,7 @@ static int __init intel_iommu_setup(char *str) pr_warn("intel_iommu=forcedac deprecated; use iommu.forcedac instead\n"); iommu_dma_forcedac = true; } else if (!strncmp(str, "strict", 6)) { - pr_info("Disable batched IOTLB flush\n"); + pr_warn("intel_iommu=strict deprecated; use iommu.strict instead\n"); intel_iommu_strict = 1;
Also update Documentation/admin-guide/kernel-parameters.txt accordingly.
