Subject: [PATCH] soc/fsl/bqman: page align iommu mapping sizes
|
|
|
|
Prior to calling iommu_map()/iommu_unmap() page align the size or
|
|
failures such as below could happen:
|
|
|
|
iommu: unaligned: iova 0x... pa 0x... size 0x4000 min_pagesz 0x10000
|
|
qman_portal 500000000.qman-portal: failed to iommu_map() -22
|
|
|
|
Seen when booted a kernel compiled with 64K page size support.
