drm/simple_kms_helper: Add {enable|disable}_vblank callback support

2018-04-19T04:10:22+00:00

If simple_kms_helper based driver needs to work with vblanks, then it has to provide drm_driver.{enable|disable}_vblank callbacks, because drm_simple_kms_helper.drm_crtc_funcs does not provide any. At the same time drm_driver.{enable|disable}_vblank callbacks are marked as deprecated and shouldn't be used by new drivers. Fix this by extending drm_simple_kms_helper.drm_crtc_funcs to provide the missing callbacks.

drm: introduce drm_dev_{get/put} functions

2018-04-19T04:10:22+00:00

Reference counting functions in the kernel typically use get/put suffixes. For maintaining coding style consistency, introduce drm_dev_{get/put} functions. All callers of drm_dev_ref() API have been converted in this patch and hence it has been dropped while the drm_dev_unref() API with non-trivial number of users remains for compatibility. The semantic patch scripts/coccinelle/api/drm-get-put.cocci has been updated with the new helper for conversion of drm_dev_unref() to drm_dev_put() Signed-off-by: Aishwarya Pant Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/6babda56134035a98220d5d37a4fd4048df214ce.1506413698.git.aishpant@gmail.com (cherry picked from commit 9a96f55034e41b4e002b767e9218d55f03bdff7d) Signed-off-by: Joel Stanley

drm/syncobj: Add a callback mechanism for replace_fence (v3)

2017-08-28T20:26:42+00:00

It is useful in certain circumstances to know when the fence is replaced in a syncobj. Specifically, it may be useful to know when the fence goes from NULL to something valid. This does make syncobj_replace_fence a little more expensive because it has to take a lock but, in the common case where there is no callback list, it spends a very short amount of time inside the lock. v2: - Don't lock in drm_syncobj_fence_get. We only really need to lock around fence_replace to make the callback work. v3: - Fix the cb_list comment to make kbuild happy Signed-off-by: Jason Ekstrand Signed-off-by: Dave Airlie

drm/syncobj: Add a race-free drm_syncobj_fence_get helper (v2)

2017-08-28T20:20:30+00:00

The atomic exchange operation in drm_syncobj_replace_fence is sufficient for the case where it races with itself. However, if you have a race between a replace_fence and dma_fence_get(syncobj->fence), you may end up with the entire replace_fence happening between the point in time where the one thread gets the syncobj->fence pointer and when it calls dma_fence_get() on it. If this happens, then the reference may be dropped before we get a chance to get a new one. The new helper uses dma_fence_get_rcu_safe to get rid of the race. This is also needed because it allows us to do a bit more than just get a reference in drm_syncobj_fence_get should we wish to do so. v2: - RCU isn't that scary - Call rcu_read_lock/unlock - Don't rename fence to _fence - Make the helper static inline Signed-off-by: Jason Ekstrand Acked-by: Christian König (v1) Signed-off-by: Dave Airlie

drm/syncobj: Rename fence_get to find_fence

2017-08-28T20:17:37+00:00
