[Freedreno] [PATCH v3 12/13] drm/msm/dpu: add atomic private object to dpu kms

Subclass drm private state for DPU for handling driver specific data. Adds atomic private object and private object lock to dpu kms. Provides helper function to retrieve DPU private data from current atomic state. changes in v2: - none changes in v3: - rebase on [1] [1]

[Freedreno] [PATCH v3 13/13] drm/msm/dpu: use private obj to track hw resources

Switch to state based resource management. This patch overhauls the resource manager and HW allocation methods by maintaining the global resource pool and allocated hw blocks in respective drm component states. Global resource manager(RM) is tracked in private object. Allocation strategy is

[Freedreno] [PATCH v3 10/13] drm/msm/dpu: remove topology name

Strip down the support for topology enums. It can be replaced with simple hw count checks. changes in v2: - none changes in v3: - none Change-Id: If9b2a4db5bbdf8545b99b6d90825e256d014382d Signed-off-by: Jeykumar Sankaran --- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c

[Freedreno] [PATCH v3 11/13] drm/msm/dpu: remove display H_TILE from encoder

Encoder H_TILE values are not used for allocating the hw blocks. no. of hw_intf blocks provides the info. changes in v2: - none changes in v3: - none Change-Id: I1c1c13e9b9f608fbaa8c5897f9f1892029107ac5 Signed-off-by: Jeykumar Sankaran ---

Prep changes for state based resource management. Moves all the hw block tracking for the crtc to the state object. changes in v2: - none changes in v3: - none Change-Id: I2816e9e28b27f1126b477d62eb3858a30a652747 Signed-off-by: Jeykumar Sankaran ---

[Freedreno] [PATCH v3 07/13] drm/msm/dpu: avoid querying for hw intf before assignment

hw intf blocks are needed only during encoder enable to program timing engines(for video panels). encoder->enable is triggered only after atomic_modeset at which point we assign the resources for the display pipeline. This patch defers the hw_intf look-up until encoder enable. changes in v2:

[Freedreno] [PATCH v3 06/13] drm/msm/dpu: iterate for assigned hw ctl in virtual encoder

Instead of iterating for hw ctrl per physical encoder, this patch moves the iterations and assignment to the virtual encoder. changes in v2: - none changes in v3: - none Change-Id: I896a8c36d6353986582e9d0fe3da9b2293579d4b Signed-off-by: Jeykumar Sankaran ---

[Freedreno] [PATCH v3 00/13] Atomic resource management

This patchset series introduces drm private object in KMS to manage HW resource management. It modifies the resource manager by introducing API's to do per DRM object resource allocation/cleanups. Patches 00/13 to 11/13 are clean up patches to prepare DPU for the above migration. major changes
