Yeah, we shouldn't let the machine die. Are there more WARN_ON_ONCE usage we could convert to WARN_ONCE?

Hi, I think I got mmiotracing back to work on my machine. Would you please test this patch on your machines too? I still got some UNKNOWN entries in the mmiotrace file, but besides that it seems to work. I have no idea if that's the right way though, and it needs a big cleanup, but I just wanted to see if the basic idea works the patch should apply just fine on any 4.4 kernel happy

The conversion is a nice catch, but i'd like to have a bit more context, see below!

BTW, turn that irksome WARN_ON_ONCE() in drivers/gpu/drm/drm_vblank.c into a WARN_ONCE(), and all is peachy, you get the warning, box lives. ---

virtio-gpu objects never move around, so effectively they are pinned all the time. This makes the the implementation pretty easy ;) Signed-off-by: Gerd Hoffmann <kraxel at redhat.com> --- drivers/gpu/drm/virtio/virtgpu_prime.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/virtio/virtgpu_prime.c b/drivers/gpu/drm/virtio/virtgpu_prime.c index

4.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Karol Herbst <nouveau at karolherbst.de> commit cfa52c0cfa4d727aa3e457bf29aeff296c528a08 upstream. Because Linux might use bigger pages than the 4K pages to handle those mmio ioremaps, the kmmio code shouldn't rely on the pade id as it currently does. Using the memory address instead
