drm/ttm, drm/vmwgfx: Use a configuration option for the TTM dma page pool

2019-11-14T07:41:23+00:00

Drivers like vmwgfx may want to test whether the dma page pool is present or not. Since it's activated by default by TTM if compiled-in, define a hidden configuration option that the driver can test for. Cc: Christian König Signed-off-by: Thomas Hellstrom Reviewed-by: Christian König

UAPI Changes: Cross-subsystem Changes: Core Changes: * Handle UP requests asynchronously in the DP MST helpers, fixing hotplug notifications and allowing us to implement suspend/resume reprobing * Add basic suspend/resume reprobing to the DP MST helpers * Improve locking for link address reprobing and connection status request handling in the DP MST helpers * Miscellaneous refactoring in the DP MST helpers * Add a Kconfig option to the DP MST helpers to enable tracking of gets/puts for topology references for debugging purposes Driver Changes: * nouveau: Resume hotplug interrupts earlier, so that sideband messages may be transmitted during resume and thus allow suspend/resume reprobing for DP MST to work * nouveau: Avoid grabbing runtime PM references when handling short DP pulses, so that handling sideband messages in resume codepaths with the DP MST helpers doesn't deadlock us * i915, nouveau, amdgpu, radeon: Use detect_ctx for probing MST connectors, so that we can grab the topology manager's atomic lock Note: there's some amdgpu patches that I didn't realize were pushed upstream already when creating this topic branch. When they fail to apply, you can just ignore and skip them.

drm/dp_mst: Add topology ref history tracking for debugging

2019-10-24T18:36:13+00:00

For very subtle mistakes with topology refs, it can be rather difficult to trace them down with the debugging info that we already have. I had one such issue recently while trying to implement suspend/resume reprobing for MST, and ended up coming up with this. Inspired by Chris Wilson's wakeref tracking for i915, this adds a very similar feature to the DP MST helpers, which allows for partial tracking of topology refs for both ports and branch devices. This is a lot less advanced then wakeref tracking: we merely keep a count of all of the spots where a topology ref has been grabbed or dropped, then dump out that history in chronological order when a port or branch device's topology refcount reaches 0. So far, I've found this incredibly useful for debugging topology refcount errors. Since this has the potential to be somewhat slow and loud, we add an expert kernel config option to enable or disable this feature, CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS. Changes since v1: * Don't forget to destroy topology_ref_history_lock Changes since v4: * Correct order of kref_put()/topology_ref_history_unlock - we can't unlock the history after kref_put() since the memory might have been freed by that point * Don't print message on allocation error failures, the kernel already does this for us Changes since v5: * Get rid of some leftover usages of %px * Remove a leftover empty return; statement Cc: Juston Li Cc: Imre Deak Cc: Ville Syrjälä Cc: Harry Wentland Cc: Daniel Vetter Reviewed-by: Sean Paul Signed-off-by: Lyude Paul Link: https://patchwork.freedesktop.org/patch/msgid/20191022023641.8026-15-lyude@redhat.com
