[PATCH v3 RESEND 00/24] drm/exynos: add support for GSCALER planes on Exynos5433
by Andrzej Hajda 03 Mar '22

03 Mar '22

Hi Inki, GSCALERs in Exynos SoCs support conversion between wide range of image formats, plus scaling and rotation. Driver already supports mem2mem mode - via ExynosDRM IPP framework. This patchset adds support for mem to display mode - framebuffers can be converted, scaled and send directly to Display Controller. From DRM framework's point of view every GSCALER exposes drm_plane which can be connected to display controller (display panel or TV). The feature is not well documented so the development was quite difficult - a process of trial and error, vendor code analysis, guessing from datasheets. Hopefully most of the issues were solved. I have developed and tested it on TM2 device with panel and TV paths. The patchset contains three parts: 1. Preparatory patches - mostly cleanup and refactoring of drm_crtc and drm_plane related structures, to allow usage of planes which are not physically bound to crtcs (01-13). 2. Adding local path support to GSCALER and DECON (14-20). 3. Few fixes of bugs existing already in the code but discovered due to added local path support (21-23). The patchset is based on exynos_drm_next plus my patchset adding zpos to DECON and FIMD - 'drm/exynos: add support for dynamic zpos in DECON and FIMD' - it is required to allow set z-pos position of GSCALER planes. To simplify tests I have also created branch containing all required patches: Repo: https://git.tizen.org/cgit/platform/kernel/linux-exynos Branch: sandbox/ahajda/dev/exynos-drm-local-path This is v2 version of the patchset. In this version I have moved code setting cursor plane in crtc to separate patch together with code disabling fast cursor updates - hardware does not support it. To keep bisectability DTS patches should be applied before subsequent ones. It is rebased on today's exynos-drm-next. Please be aware that DTS patches has been already applied to samsung-soc tree, I left them here to simplify testing on exynos-drm-next, which is not in sync with samsung-soc, for this reason I have moved them on the beginning of the patchset.

[PATCH 0/6] drm/meson: add support for AXG & MIPI-DSI
by Neil Armstrong 20 Jan '22

20 Jan '22

The Amlogic AXG SoC family has a downgraded VPU with the following changes : - Only a single OSD plane, no overlay video plane - The primary plane doesn't support HW scaling - The pixels are read directly from DDR without any Canvas module - Doesn't support HDMI or CVBS - Ouputs only with ENCL encoder to a DPI-to-DSI Synopsys DW-MIPI-DSI transceiver The Amlogic AXg SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a), with a custom glue managing the IP resets, clock and data input similar to the DW-HDMI Glue on other Amlogic SoCs. This adds support for the Glue managing the transceiver, mimicing the init flow provided by Amlogic to setup the ENCl encoder, the glue, the transceiver, the digital D-PHY and the Analog PHY in the proper way. The DW-MIPI-DSI transceiver + D-PHY are directly clocked by the VCLK2 clock, which pixel clock is derived and feeds the ENCL encoder and the VIU pixel reader. An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the DW-MIPI-DSI transceiver.

This is an AMD Renoir system, with AMD Ryzen 5 4500U APU, This happens only, if I set 'quiet' as boot option. If I remove it, brightness restore works fine. If I boot with quiet set, after login I can do systemctl start systemd-backlight@backlight:amdgpu_bl0.service And it will successfully restore my brightness level. -- You are receiving this mail because: You are watching the assignee of the bug.
