77d9e1e6 - drm/meson: add support for MIPI-DSI transceiver

Tue, 30 May 2023 07:38:13 +0000

drm/meson: add support for MIPI-DSI transceiverThe Amlogic G12A/G12B/SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver(ver 1.21a), with a custom glue managing the IP resets, clock and datainputs similar to the DW-HDMI Glue on other Amlogic SoCs.This adds support for the Glue managing the transceiver, mimicing the initflow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver,the digital D-PHY and the Analog PHY in the proper way.An optional "MEAS" clock can be enabled to measure the delay between eachvsync feeding the DW-MIPI-DSI transceiver.Signed-off-by: Neil Armstrong Reviewed-by: Jagan Teki Reviewed-by: Nicolas Belin Tested-by: Nicolas Belin # on Khadas VIM3 + TS050 PanelSigned-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20230512-amlogic-v6-4-upstream-dsi-ccf-vim3-v5-12-56eb7a4d5b8e@linaro.org List of files: /linux-6.15/drivers/gpu/drm/meson/Makefile

Wed, 20 Oct 2021 12:39:44 +0000

drm/meson: split out encoder from meson_dw_hdmiThis moves all the non-DW-HDMI code where it should be:an encoder in the drm/meson core driver.The bridge functions are copied as-is, except:- the encoder init uses the simple kms helper- the mode_set has been moved to atomic_enable()- debug prints are converted to dev_debg()For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTORwill be handled later.The meson dw-hdmi glue is slightly fixed to live without theencoder in the same driver.Signed-off-by: Neil Armstrong Acked-by: Sam Ravnborg Acked-by: Martin Blumenstingl [narmstrong: fixed warning because missing meson_encoder_hdmi.h include]Link: https://patchwork.freedesktop.org/patch/msgid/20211020123947.2585572-4-narmstrong@baylibre.com List of files: /linux-6.15/drivers/gpu/drm/meson/Makefile

d1b5e41e - drm/meson: Add AFBCD module driver

Mon, 21 Oct 2019 09:15:05 +0000

drm/meson: Add AFBCD module driverThis adds the driver for the ARM Framebuffer Compression decoders foundin the Amlogic GXM and G12A SoCs.The Amlogic GXM and G12A AFBC decoder are totally different, the GXM onlyhandling only the AFBC v1.0 modes and the G12A decoder handling theAFBC v1.2 modes.The G12A AFBC decoder is an external IP integrated in the video pipeline,and the GXM AFBC decoder seems to the an Amlogic custom decoder moretighly integrated in the video pipeline.The GXM AFBC decoder can handle only one AFBC plane for 2 availableOSD planes available in HW, and the G12A AFBC decoder can handle upto 4 AFBC planes for up to 3 OSD planes available in HW.The Amlogic GXM supports 16x16 SPARSE and 16x16 SPLIT AFBC buffers upto 4k.On the other side, for G12A SPLIT is mandatory in 16x16 block mode, butfor 4k modes 32x8+SPLIT AFBC buffers is manadatory for performances reasons.The RDMA is used here to reset and program the AFBC decoder uniton each vsync without involving the interrupt handler that canbe masked for a long period of time, producing display glitches.For this we use the meson_rdma_writel_sync() which adds the registerwrite tuple (VPU register offset and register value) to the RDMA bufferand write the value to the HW.When enabled, the RDMA is enabled to rewrite the same sequence at thenext VSYNC event, until a new buffer is committed to the OSD plane.Then the Amlogic G12A is switched to RDMA, the Amlogic GXM Decoderdoesn't need a reset/reprogram at each vsync, but needs to keep thevsync interrupt enabled to trigger the RDMA module.Signed-off-by: Neil Armstrong Reviewed-by: Kevin Hilman [narmstrong: fixed typo in commit log]Link: https://patchwork.freedesktop.org/patch/msgid/20191021091509.3864-6-narmstrong@baylibre.com List of files: /linux-6.15/drivers/gpu/drm/meson/Makefile

63fba242 - drm/meson: add RDMA module driver

Mon, 21 Oct 2019 09:15:04 +0000

drm/meson: add RDMA module driverThe VPU embeds a "Register DMA" that can write a sequence of registerson the VPU AHB bus, either manually or triggered by an internal IRQevent like VSYNC or a line input counter.The initial implementation handles a single channel (over 8), triggeredby the VSYNC irq and does not handle the RDMA irq.The RDMA will be usefull to reset and program the AFBC decoder uniton each vsync without involving the interrupt handler that canbe masked for a log period of time, producing display glitches.Signed-off-by: Neil Armstrong Reviewed-by: Kevin Hilman Link: https://patchwork.freedesktop.org/patch/msgid/20191021091509.3864-5-narmstrong@baylibre.com List of files: /linux-6.15/drivers/gpu/drm/meson/Makefile

f9a23481 - drm/meson: Support Overlay plane for video rendering

Tue, 06 Nov 2018 09:40:00 +0000

drm/meson: Support Overlay plane for video renderingThe Amlogic Meson GX SoCs support an Overlay plane behind the primaryplane for video rendering.This Overlay plane support various YUV layouts :- YUYV- NV12 / NV21- YUV444 / 422 / 420 / 411 / 410The scaler supports a wide range of scaling ratios, but for simplicity,plane atomic check limits the scaling from x5 to /5 in vertical andhorizontal scaling.The z-order is fixed and always behind the primary plane and cannot be changed.The scaling parameter algorithm was taken from the Amlogic vendor kernelcode and rewritten to match the atomic universal plane requirements.The video rendering using this overlay plane support has been tested usingthe new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2MemHardware Video Decoder up to 3840x2160 NV12 frames on various display modes.Signed-off-by: Neil Armstrong Acked-by: Daniel Vetter Tested-by: Maxime Jourdan Link: https://patchwork.freedesktop.org/patch/msgid/1541497202-20570-2-git-send-email-narmstrong@baylibre.com List of files: /linux-6.15/drivers/gpu/drm/meson/Makefile
