Since DPU doesn't support the sequence anymore, clean up the support from RM. Replace rsvp with the corresponding encoder id to tag the HW blocks reserved. It prepares DPU to get rid of RM altogether and track reservations using private states. changes in v2: - none Signed-off-by: Jeykumar Sankaran Reviewed-by: Sean Paul --- drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c | 284 +++++---------------------------- drivers/gpu/drm/msm/disp/dpu1/dpu_rm.h | 4 - 2 files changed, 43 insertions(+), 245 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c index bdb1177..36a929b 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c @@ -21,8 +21,8 @@ #include "dpu_encoder.h" #include "dpu_trace.h" -#define RESERVED_BY_OTHER(h, r) \ - ((h)->rsvp && ((h)->rsvp->enc_id != (r)->enc_id)) +#define RESERVED_BY_OTHER(h, r) \ + ((h)->enc_id && (h)->enc_id != r) /** * struct dpu_rm_requirements - Reservation requirements parameter bundle @@ -34,85 +34,23 @@ struct dpu_rm_requirements { struct dpu_encoder_hw_resources hw_res; }; -/** - * struct dpu_rm_rsvp - Use Case Reservation tagging structure - * Used to tag HW blocks as reserved by a CRTC->Encoder->Connector chain - * By using as a tag, rather than lists of pointers to HW blocks used - * we can avoid some list management since we don't know how many blocks - * of each type a given use case may require. - * @list: List head for list of all reservations - * @seq: Global RSVP sequence number for debugging, especially for - * differentiating differenct allocations for same encoder. - * @enc_id: Reservations are tracked by Encoder DRM object ID. - * CRTCs may be connected to multiple Encoders. - * An encoder or connector id identifies the display path. - */ -struct dpu_rm_rsvp { - struct list_head list; - uint32_t seq; - uint32_t enc_id; -}; /** * struct dpu_rm_hw_blk - hardware block tracking list member * @list: List head for list of all hardware blocks tracking items - * @rsvp: Pointer to use case reservation if reserved by a client - * @rsvp_nxt: Temporary pointer used during reservation to the incoming - * request.
