Some processes, such as systemd, are only polling for EPOLLERR|EPOLLHUP. As drm_file uses unkeyed wakeups, such a poll receives many spurious wakeups from uninteresting events. Use keyed wakeups to allow the wakeup target to more efficiently discard these uninteresting events. Signed-off-by:

This is leftovers from the old drm_driver->load callback upside-down issues. It doesn't do anything for not-hotplugged connectors since drm_dev_register takes care of that. Acked-by:

As usual, we can drop the drm_dev_put() and need to embed the drm_device. Since it's so few, also go right ahead and leave drm_device->dev_private set to NULL, so that we always use the container_of() upcast, which is faster anyway. Acked-by:

Komeda uses the component framework, which does open/close a new devres group around all the bind callbacks. Which means we can use devm_ functions for managing the drm_device cleanup, with leaking stuff in case of deferred probes or other reasons to unbind components, or the component_master. Also note that this fixes a double-free in the probe unroll code, bot drm_dev_put and kfree(kms) result in the kms allocation getting freed. Aside: komeda_bind could be cleaned up a lot, devm_kfree is a bit redundant. Plus I'm not clear on why there's suballocations for mdrv->mdev and mdrv->kms. Plus I'm not sure the lifetimes are correct with all that devm_kzalloc usage ... That structure layout is also the reason why komeda still uses drm_device->dev_private and can't easily be replaced with a proper container_of upcasting. I'm pretty sure that there's endless amounts of hotunplug/hotremove bugs in there with all the unprotected dereferencing of drm_device->dev_private. Reviewed-by:

We're mostly there already, just a handful of places that didn't use the to_udl container_of cast. To make sure no new appear, don't set ->dev_private. Reviewed-by:

With Thomas' patch to clean up fbdev init this is a rather standard conversion to the new wrapper macro. v2: Rebase on top of Thomas' patches to remove the return value from drm_fbdev_generic_setup() v3: Update commit message to reflect the reality of the rebased patch (Sam) Reviewed-by:

We already have it in v3d_dev->drm.dev with zero additional pointer chasing. Personally I don't like duplicated pointers like this because: - reviewers need to check whether the pointer is for the same or different objects if there's multiple - compilers have an easier time too To avoid having to pull in some big headers I implemented the casting function as a macro instead of a static inline. Typechecking thanks to container_of still assured. But also a bit a bikeshed, so feel free to ignore. v2: More parens for v3d_to_pdev macro (checkpatch) Acked-by:

Doesn't apply to upstream kernels since a rather long time. Reviewed-by:

Daniel Vetter authored
Add a new macro helper to combine the usual init sequence in drivers, consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree triplet. This allows us to remove the rather unsightly drmm_add_final_kfree from all currently merged drivers. The kerneldoc is only added for this new function. Existing kerneldoc and examples will be udated at the very end, since once all drivers are converted over to devm_drm_dev_alloc we can unexport a lot of interim functions and make the documentation for driver authors a lot cleaner and less confusing. There will be only one true way to initialize a drm_device at the end of this, which is going to be devm_drm_dev_alloc. v2: - Actually explain what this is for in the commit message (Sam) - Fix checkpatch issues (Sam) Acked-by:
