Commit 9a295ff0ffc9 attempted to rectify this by removing the newline from the pci_info format string, but this doesn't work, as pci_info calls implicitly append a newline anyway. Printing the decoded features on the same line would make it quite long. Instead, change pci_info() to pr_info() to omit PCI bus location info, which is also shown in the preceding message. This results in: pci 0000:00:00.2: AMD-Vi: Found IOMMU cap 0x40 AMD-Vi: Extended features (0x206d73ef22254ade): PPR X2APIC NX GT IA GA PC GA_vAPIC AMD-Vi: Interrupt remapping enabled Fixes: 9a295ff0ffc9 ("iommu/amd: Print extended features in one line to fix divergent log levels") Link: https://lore.kernel.org/lkml/alpine.LNX.2.20.13.2104112326460.11104@monopod.intra.ispras.ru Signed-off-by: Alexander Monakov Cc: Paul Menzel Cc: Joerg Roedel Cc: Suravee Suthikulpanit Cc: iommu@lists.linux-foundation.org Reviewed-by: Paul Menzel Link: https://lore.kernel.org/r/20210504102220.1793-1-amonakov@ispras.ru Signed-off-by: Joerg Roedel Signed-off-by: Sasha Levin --- drivers/iommu/amd/init.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/iommu/amd/init.c b/drivers/iommu/amd/init.c index cc9869cc48e4..fa57986c2309 100644 --- a/drivers/iommu/amd/init.c +++ b/drivers/iommu/amd/init.c @@ -1914,8 +1914,8 @@ static void print_iommu_info(void) pci_info(pdev, "Found IOMMU cap 0x%hx\n", iommu->cap_ptr); if (iommu->cap & (1 << IOMMU_CAP_EFR)) { - pci_info(pdev, "Extended features (%#llx):", - iommu->features); + pr_info("Extended features (%#llx):", iommu->features); + for (i = 0; i < ARRAY_SIZE(feat_str); ++i) { if (iommu_feature(iommu, (1ULL << i))) pr_cont(" %s", feat_str[i]); -- 2.30.2
