Subject: [PATCH] app/test: fix DMA API tests in IOVA as PA mode
Date: Thu, 27 Feb 2025 13:27:49 +0000 [thread overview]
Message-ID: <20250227132749.753581-1-bruce.richardson@intel.com> (raw)
When running without IOMMU for address translation, i.e. IOVAs are
physical rather than virtual addresses, we need to translate the
pointers to IOVAs for the completion API tests.
Fixes: 9942ebb9c698 ("test/dma: add dmadev API test")
