Subject: [PATCH kernel v3 0/2] DMA, powerpc/dma: Fallback to dma_ops when persistent memory present
Date: Wed, 28 Oct 2020 18:00:28 +1100 [thread overview]
Message-ID: <20201028070030.60643-1-aik@ozlabs.ru> (raw)
This allows mixing direct DMA (to/from RAM) and
IOMMU (to/from apersistent memory) on the PPC64/pseries
platform.
This replaces https://lkml.org/lkml/2020/10/27/418
which replaces https://lkml.org/lkml/2020/10/20/1085
This is based on sha1
4525c8781ec0 Linus Torvalds "scsi: qla2xxx: remove incorrect sparse #ifdef".
Please comment. Thanks.
