Subject: [PATCH] iommu/vt-d: Print pasid table entries MSB to LSB in debugfs
Date: Sun, 21 Jul 2019 17:22:07 -0700	[thread overview]
Message-ID: <20190722002207.22649-1-sai.praneeth.prakhya@intel.com> (raw)

Commit dd5142ca5d24 ("iommu/vt-d: Add debugfs support to show scalable mode
DMAR table internals") prints content of pasid table entries from LSB to
MSB where as other entries are printed MSB to LSB. So, to maintain
uniformity among all entries and to not confuse the user, print MSB first.
