1. Bug in ARM64 DMA subsystem.
2. Bug in IOMMU driver.
3. Bug in another newly introduced driver. The new driver would hog the
CPU and won't allow HIDMA interrupts to execute. Therefore, the test
times out.
Which driver?
Wouldn't these problems already be exposed by dmatest? I was asking
whether it's possible that, every now and then, your DMA internal test
could fail and then the driver would unload. I'm not talking about hard
bugs in other code that always causes the DMA driver test to fail.
