2020-01-15drm/nouveau/fault: Add support for GP10BThierry Reding
There is no BAR2 on GP10B and there is no need to map through BAR2 because all memory is shared between the GPU and the CPU. Add a custom implementation of the fault sub-device that uses nvkm_memory_addr() instead of nvkm_memory_bar2() to return the address of a pinned fault buffer.

2019-02-20drm/nouveau/fault/gp100: expose MaxwellFaultBufferABen Skeggs
This nvclass exposes the replayable fault buffer, which will be used by SVM to manage GPU page faults. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-12-11drm/nouveau/fault: add explicit control over fault buffer interruptsBen Skeggs
The GPU will continually fire interrupts while a fault buffer GET != PUT, and to stop the spurious interrupts while the handler does its thing, we were disabling the fault buffer temporarily. This is not actually a great idea to begin with, and made worse by Volta resetting GET/PUT when it's reactivated. So, let's not do that. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
