Initially ARC PGU required real encoder/trnasmitter to exist. That was fine for real HW such as ARC SDP boards. But on some simulaiton platroms like ARC VDK or nSIM OSCI we have model of the same ARC PGU and ability to output video data in a virtual LCD. To make ARC PGU driver usable in those virtual platforms we need to istantiate virtual encoder instead of a real one. And that all is done in the first patch of the series. Subsequent patches just update configs of both VDK and nSIM OSCI boards with enabling ARC PGU driver and adding required fixups in their DT descriptions. Changes v1 -> v2: * Got rid of dummy arcpgu_drm_encoder_helper_funcs and now rely on default best encoder Alexey Brodkin (2): ARCv2: [vdk] Enable ARC PGU on HS38 VDK ARC: [nsimosci] Enable ARC PGU on nSIM OSCI virtual platforms Ruud Derwig (1): drm/arcpgu: Make ARC PGU usable on simulation platforms arch/arc/boot/dts/nsimosci.dts | 14 +++- arch/arc/boot/dts/nsimosci_hs.dts | 14 +++- arch/arc/boot/dts/nsimosci_hs_idu.dts | 14 +++- arch/arc/boot/dts/vdk_axs10x_mb.dtsi | 13 ++- arch/arc/boot/dts/vdk_hs38_smp.dts | 2 +- arch/arc/configs/nsimosci_defconfig | 3 +- arch/arc/configs/nsimosci_hs_defconfig | 3 +- arch/arc/configs/nsimosci_hs_smp_defconfig | 3 +- arch/arc/configs/vdk_hs38_smp_defconfig | 7 +- drivers/gpu/drm/arc/Makefile | 2 +- drivers/gpu/drm/arc/arcpgu.h | 1 + drivers/gpu/drm/arc/arcpgu_drv.c | 15 ++-- drivers/gpu/drm/arc/arcpgu_sim.c | 128 +++++++++++++++++++++++++++++ 13 files changed, 189 insertions(+), 30 deletions(-) create mode 100644 drivers/gpu/drm/arc/arcpgu_sim.c -- 2.5.5 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
