similar to: v3.17, i915 vs nouveau: possible recursive locking detected

We need ww mutexes and need to rewrite i915 a bit fo fix this all. I.e. known issue. As long as your userspace isn't nasty nothing bad will ever happen though. -Daniel On Mon, Oct 13, 2014 at 08:40:33PM +0200, Marcin ?lusarz wrote: > ============================================= > [ INFO: possible recursive locking detected ] > 3.17.0 #50 Not tainted >

Hi, While trying PRIME, I got a lockdep warning after exiting glxgears. Is it harmful? The command was: DRI_PRIME=1 glxgears Offload provider is a GT425M (NVC0), output sink is an Intel i5-460M. Kind regards, Peter dmesg: ============================================= [ INFO: possible recursive locking detected ] 3.15.0-rc8-custom-00058-gd2cfd31 #1 Tainted: G O

Eventually the streets will run with blood and we'll enter

This patch moves the virtio_gpu_cmd_create_resource() call (which notifies the host about the new resource created) into the virtio_gpu_object_create() function. That way we can call virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host already knows about the object when ttm initializes the object and calls our driver callbacks. Specifically the object is already created when the
