Subject: [PATCH 6.6.y 0/1] Fix ppc64 build error introduced in v6.6.161
Date: Thu, 5 Nov 2026 15:24:00 -0800 [thread overview]
Message-ID: <20261105232402.4033385-1-stephen.s.brennan@oracle.com> (raw)
Hello,
Drgn builds stable kernels regularly in order to run its test suite against. We
encountered an error compiling v6.6.161 for ppc64.
The 6.6.161 update contained "powerpc/iommu: Move pSeries specific functions to
pseries/iommu.c" [1]. On ppc64 configurations without CONFIG_IOMMU_API, this
breaks the build (details in the patch).
Thank you!
Stephen
