Is that correct? > > Regards, > Matthias > >From a hardware point of view, the HW engines of vdosys0 and vdosys1 are different. 1. The components on meiatek-drm of vdosys0 are OVL0, RDMA0, COLOR0, CCORR, AAL0, GAMMA, DITHER, DSC0, MERGE0, DP_INTF0. Its output panel is eDP. 2. The components on meiatek-drm of vdosys1 are OVL_ADAPTOR, MERGE5, DP_INTF1. Its output panel is DP. In the SoC before, such as mt8173, it has 2 pipelines binding to one mmsys with the same clock driver and the same power domain. In mt8195, 2 pipelines are binding to different mmsys, such as vdosys0 and vdosys1. Each mmsys uses different clock drivers and different power domains. So I think it is more appropriate to use 2 compatibles to identify which mmsys represents the pipeline. Another reason for using two compatibles is that we use different driver data in mtk-mmsys.c and mtk_drm_drv.c to identify the corresponding mmsys is vdosys0 or vdosys1. Their driver data in mtk_drm_drv.c is defined here: [v7,13/13] drm/mediatek: add mediatek-drm of vdosys0 support for mt8195 https://patchwork.kernel.org/project/linux-mediatek/patch/20210815145610.2050-14-jason-jh.lin@xxxxxxxxxxxx/ [v2,14/14] drm/mediatek: add mediatek-drm of vdosys1 support for MT8195 https://patchwork.kernel.org/project/linux-mediatek/patch/20210722094551.15255-15-nancy.lin@xxxxxxxxxxxx/ There is another series talking about the two mmsys compatible. https://patchwork.kernel.org/project/linux-mediatek/patch/20210722092624.14401-2-jason-jh.lin@xxxxxxxxxxxx/ Regards, Nancy > > > > + .data = &mt8195_vdosys1_driver_data, > > > > + }, > > > > { } > > > > }; > > > > > > > > diff --git a/include/linux/soc/mediatek/mtk-mmsys.h > > > > b/include/linux/soc/mediatek/mtk-mmsys.h > > > > index 34cb605e5df9..338c71570aeb 100644 > > > > --- a/include/linux/soc/mediatek/mtk-mmsys.h > > > > +++ b/include/linux/soc/mediatek/mtk-mmsys.h > > > > @@ -49,6 +49,8 @@ enum mtk_ddp_comp_id { > > > > DDP_COMPONENT_DSC1, > > > > DDP_COMPONENT_DSC1_VIRTUAL0, > > > > DDP_COMPONENT_DP_INTF0, > > > > + DDP_COMPONENT_DP_INTF1, > > > > + DDP_COMPONENT_PSEUDO_OVL, > > > > DDP_COMPONENT_ID_MAX, > > > > }; > > > > > > > > -- > > > > 2.18.0 > > > >
