I successfully tested videoengine (tested 2k,4k,hevc,h264 and 4k hdr hevc (with non hdr output)). I found the problem in VI (video) layer in DRM (displayengine) output. I must change at least once after poweron DRM property "COLOR_RANGE" to DRM_COLOR_YCBCR_FULL_RANGE to get correctly setup CSC (color space conversion) in hw 🤨, lost 3 days in kernel debug.

This code does not seem to be right: #define SUN50I_H616_NVMEM_MASK 0x22 #define SUN50I_H616_NVMEM_SHIFT 5 ... u32 efuse_value = (*(u32 *)efuse >> SUN50I_H616_NVMEM_SHIFT) & SUN50I_H616_NVMEM_MASK; ... if (efuse_value >=1 && efuse_value <= 3) Are you sure about MASK ? Or it is bitmask that should be translated like A100 -> https://www.lkml.org/lkml/2020/12/8/70

I tested with kernel 6.2RC4 (some driver code change needed), notes: do not increase GPU voltage reg_dcdcc: dcdcc { regulator-always-on; regulator-min-microvolt = <810000>; - regulator-max-microvolt = <1080000>; + regulator-max-microvolt = <1100000>; regulator-name = "vdd-gpu-sys"; }; absolute maximum (from H616_Datasheet_V1.0_cleaned.pdf): recommended (from H616_Datasheet_V1.0_cleaned.pdf): my sun50i-h616-orangepi-zero2.dts: reg_dcdcc: dcdcc { regulator-always-on; regulator-min-microvolt = <810000>; regulator-max-microvolt = <990000>; regulator-name = "vdd-gpu-sys"; }; I also reworked temperature - cooling my sun50i-h616.dtsi: cpu_thermal: cpu-thermal { polling-delay-passive = <500>; polling-delay = <1000>; thermal-sensors = <&ths 2>; trips { cpu_target: cpu-target { temperature = <75000>; hysteresis = <2000>; type = "passive"; }; critical { temperature = <105000>; hysteresis = <2000>; type = "critical"; }; }; cooling-maps { map0 { trip = <&cpu_target>; cooling-device = <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>, <&cpu1 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>, <&cpu2 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>, <&cpu3 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>; }; }; }; my sun50i-h616-orangepi-zero2.dts: &cpu_thermal { /delete-node/ trips; // beaware, all points must have different names otherwise dts compiller does not hold position and driver stuck in differnt trip point trips { cpu_warm: cpu_warm { temperature = <75000>; hysteresis = <2000>; type = "passive"; }; cpu_hot_pre: cpu_hot_pre { temperature = <80000>; hysteresis = <2000>; type = "passive"; }; cpu_hot: cpu_hot { temperature = <85000>; hysteresis = <2000>; type = "passive"; }; cpu_very_hot: cpu_very_hot { temperature = <90000>; hysteresis = <2000>; type = "passive"; }; cpu_critical { temperature = <105000>; hysteresis = <2000>; type = "critical"; }; }; /delete-node/ cooling-maps; cooling-maps { cpu_warm_limit_cpu { trip = <&cpu_warm>; cooling-device = <&cpu0 THERMAL_NO_LIMIT 2>; }; cpu_hot_pre_limit_cpu { trip = <&cpu_hot_pre>; cooling-device = <&cpu0 3 3>; }; cpu_hot_limit_cpu { trip = <&cpu_hot>; cooling-device = <&cpu0 4 4>; }; cpu_very_hot_limit_cpu { trip = <&cpu_very_hot>; cooling-device = <&cpu0 5 THERMAL_NO_LIMIT>; }; }; }; my testing 0 - idle 10 - run "stress --cpu 4" 36 - additional external heating 134 - remove heating 304 - stop "stress --cpu 4"

So the question, the armbian patches are well aligned with the new kernel, why are they not pushed to mainline ? Do you also have a terrible experience with linux mainlining process ?

I was successful to boot uBoot over SPI-FLASH and continue to boot over network (PXE+NFS), and my few comments: uboot (orangepi) - https://github.com/orangepi-xunlong/u-boot-orangepi.git (v2021.10-sunxi) does not support SPI-FLASH boot upstream uboot hungs, but it has patch to support SPI boot (since v2023.01-rc1) - https://patchwork.ozlabs.org/project/uboot/list/?series=252044&state=* - https://github.com/u-boot/u-boot/commit/e50ee3a8d7328142eb24741305f751e5c0952380 so I extend 1. with 2.

Thanks. I cannot find your work under H616 and Allwinner is too generic. Can you navigate me to the right patch (maybe WIP repo outside patch queue) ? h616 patchwork allwinner patchwork

Hello. I see some progress in H616 (OPIZ2) support in mainline linux (now 6.2RC5 comes with USB) - https://linux-sunxi.org/Linux_mainlining_effort . I tried to setup/enable some other components and I am successful with upstream linux kernel 6.2RC5: - displayengine (drm, fb, mixer, tcon, hdmi) (seems to have some I2C/EDID problems) - videoengine (cedrus) (in testing now) - gpu (3d mali, panfrost) - dma, efuse, thermal ... but I am unsuccessful with - crypto (total different behavior in contrast to H616 manual) and untested - audio codecs and hdmi audio - opp power management (frequency + voltage) for CPU and GPU - SDIO wifi I was also successful with uBoot (some patches from upstream uBoot) to boot sdcard-less from SPI flash and then from network PXE+NFS. Does anyone do some work in this direction ?
