Overall idea: Detect lockups by watching for timeouts (vm flush / fence), return -EIOs, handle them at ioctl level, reset the GPU and repeat last ioctl. GPU reset is done by doing suspend / resume cycle with few tweaks: - CPU-only bo eviction - ignoring vm flush / fence timeouts - shortening waits Signed-off-by: Marcin Slusarz <marcin.slusarz at gmail.com> ---
