drm: Allow determining if current task is output poll worker

2018-03-18T10:17:48Z

commit 25c058ccaf2ebbc3e250ec1e199e161f91fe27d4 upstream. Introduce a helper to determine if the current task is an output poll worker. This allows us to fix a long-standing deadlock in several DRM drivers wherein the ->runtime_suspend callback waits for the output poll worker to finish and the worker in turn calls a ->detect callback which waits for runtime suspend to finish. The ->detect callback is invoked from multiple call sites and waiting for runtime suspend to finish is the correct thing to do except if it's executing in the context of the worker. v2: Expand kerneldoc to specifically mention deadlock between output poll worker and autosuspend worker as use case.

drm: extra printk() wrapper macros

2017-12-16T09:33:49Z

commit 30b0da8d556e65ff935a56cd82c05ba0516d3e4a upstream. We had only DRM_INFO() and DRM_ERROR(), whereas the underlying printk() provides several other useful intermediate levels such as NOTICE and WARNING. So this patch fills out the set by providing both regular and once-only macros for each of the levels INFO, NOTICE, and WARNING, using a common underlying macro that does all the token-pasting. DRM_ERROR is unchanged, as it's not just a printk wrapper. v2: Fix whitespace, missing ## (Eric Engestrom) Signed-off-by: Dave Gordon Reviewed-by: Eric Engestrom Cc: dri-devel@lists.freedesktop.org Acked-by: Dave Airlie Signed-off-by: Tvrtko Ursulin Cc: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

drm/ttm, drm/vmwgfx: Relax permission checking when opening surfaces

2017-04-12T10:38:33Z

commit fe25deb7737ce6c0879ccf79c99fa1221d428bf2 upstream. Previously, when a surface was opened using a legacy (non prime) handle, it was verified to have been created by a client in the same master realm. Relax this so that opening is also allowed recursively if the client already has the surface open. This works around a regression in svga mesa where opening of a shared surface is used recursively to obtain surface information.

drm/prime: Pass the right module owner through to dma_buf_export()

2016-10-31T10:13:57Z

commit 56a76c0123d6cb034975901c80fce2627338ef9e upstream. dma_buf_export() adds a reference to the owning module to the dmabuf (to prevent the driver from being unloaded whilst a third party still refers to the dmabuf). However, drm_gem_prime_export() was passing its own THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right owner from the device->fops instead. v2: Use C99 initializers to zero out unset elements of dma_buf_export_info v3: Extract the right module from dev->fops.
