If there are two DCE, then DSC_2 and DSC_3 belong to dsc_1Ah, I see now. So, the block register space is the following: DCEi -> common dsc0_enc dsc1_enc dsc0_ctl dsc1_ctlInstead of declaring a single DCE unit with two DSC blocks, we declare two distinct DSC blocks. This raises a question, how independent are these two parts of a single DCE block? For example, can we use them to perform compression with different parameters? Or use one of them for the DP DSC and another one for DSI DSC? Can we have the following configuration:DSC_0 => DP DSC DSC_1, DSC_2 => DSI DSC in DSC_MERGE topology?no, For merge mode you have to use same DCE, such as DSC_2 and DSC3 (pair)Ok, this is for the merge mode. So the dpu_rm should be extended to allocate them in pairs if merge mode is requested.What about using DSC_0 for DP and DSC_1 for DSI? Is it possible?I never do that, but i think it should works since they can work independently.Good, thanks for the confirmation. For v2, could you please describe this arrangement of DCE -> 2xDSC in a comment close to DSC_BLK_1_2 and corresponding sblk definitions?Also could you please fix dpu_rm to allocate DSC blocks in pairs for DSC_MERGE mode.
yes, I will fix DSC_MERGE mode at next patch serial.
Last, but not least, would it make sense to name the blocks as "dceN" instead of "dscN"?+ DSC_BLK_1_2("dsc_1", DSC_2, 0x81000, 0x100, BIT(DPU_DSC_NATIVE_422_EN), sm8550_dsc_sblk_0), + DSC_BLK_1_2("dsc_1", DSC_3, 0x81000, 0x100, BIT(DPU_DSC_NATIVE_422_EN), sm8550_dsc_sblk_1),+}; + static const struct dpu_intf_cfg sm8550_intf[] = {INTF_BLK("intf_0", INTF_0, 0x34000, 0x280, INTF_DP, MSM_DP_CONTROLLER_0, 24, INTF_SC7280_MASK, MDP_SSPP_TOP0_INTR, 24, 25),/* TODO TE sub-blocks for intf1 & intf2 */ @@ -218,6 +235,8 @@ const struct dpu_mdss_cfg dpu_sm8550_cfg = { .dspp = sm8550_dspp, .pingpong_count = ARRAY_SIZE(sm8550_pp), .pingpong = sm8550_pp, + .dsc = sm8550_dsc, + .dsc_count = ARRAY_SIZE(sm8550_dsc), .merge_3d_count = ARRAY_SIZE(sm8550_merge_3d), .merge_3d = sm8550_merge_3d, .intf_count = ARRAY_SIZE(sm8550_intf),diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.cindex 03f162a..be08158 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c @@ -1,6 +1,6 @@ // SPDX-License-Identifier: GPL-2.0-only/* Copyright (c) 2015-2018, The Linux Foundation.
