Subject: [PATCH 00/13] drm/tyr: add debugfs support
Date: Thu, 26 Mar 2026 14:52:53 +0800 [thread overview]
Message-ID: <20260326-b4-tyr-debugfs-v1-0-074badd18716@linux.dev> (raw)
This patchset contains:
- hazptr: Add hazard pointer abstraction to kernel::sync
- revocable: Introduce HazPtrRevocable, and adapt Gary Guo's downstream
LazyRevocable implementation to use hazard pointers internally,
enabling safe sharing of debugfs-root data across the tyr module and
DRM driver
- drm: Add device and GEM helper functions to support debugfs
- tyr: Add debugfs infrastructure and interfaces to expose GEM/VM
information
See the full dependency and commit history at [1].
