Subject: [RFC PATCH 0/2] tests/qtest: Enable spapr dma tests
Date: Tue, 15 Apr 2025 18:19:12 +1000 [thread overview]
Message-ID: <20250415081914.378236-1-npiggin@gmail.com> (raw)
I took a look at the spapr buggy msix fixme in qtests... AFAIKS
it turns out to be DMA entirely broken due to iommu not set up.
Adding a quick workaround for spapr gets everything working
properly other than exposing bugs in msi message endianness
conversions.
Thanks,
Nick
