drm/amdgpu: fix bad DMA from INTERRUPT_CNTL2 2019-11-22T19:35:10+00:00 Sam Bobroff sbobroff@linux.ibm.com 2019-11-17T23:53:54+00:00 3d0e3ce52ce3eb4b9de3caf9c38dbb5a4d3e13c3 The INTERRUPT_CNTL2 register expects a valid DMA address, but is currently set with a GPU MC address. This can cause problems on systems that detect the resulting DMA read from an invalid address (found on a Power8 guest). Instead, use the DMA address of the dummy page because it will always be safe.
