    jernej got a reaction from Werner in Allwinner sun8i creates trace when scaning for WiFi   
    Here is early work for proper XR819 mainline support. Tests reports are welcome, to see if it is actually any better than vendor driver. I got reasonable speed using it and only problem I can see is that suspend doesn't work. Of course, developer tests rarely last more than a few minutes, so long term stability isn't known.
     
    Note, I extracted pretty recent FW binaries from H616 Android box, which should be better than old ones, in theory.

    jernej got a reaction from Werner in Orange PI Lite2 no more 1920x1080 - kernel 5.5.x   
    I found the culprit. Patch https://github.com/armbian/build/blob/master/patch/kernel/archive/sunxi-5.13/board-h6-orangepi-lite2-fix-missing-all.patch messes up HDMI node, which then doesn't properly enable DDC lines and then in turn, HDMI driver can't read EDID.
     
    @Igor any reason for above patch to be so big? OPi Lite2 is pretty well supported in 5.13. Only nodes which are not present in mainline are spi0, usb3phy and dwc3. Patch can be much smaller...

    @Cesar Berci it got me interested enough that I ported changes to v5.10 with cleaner approach. Here you have commit: https://github.com/jernejsk/linux-1/commit/ad153ef6ee5be33531187f97d5fa0c07455dc795
    NOTE: You have to enable tve node in DT you want. I did that in OPi PC.

    Check U-Boot output on serial. It should say something like 4 GiB of RAM detected, 3 GiB used. That won't change, since it's impossible to use that extra GiB due to HW limitations.

    @XFer012Above DT change will most probably lock up CPU - CPU is changing clock from which it is running. Much safer bet is to change CONFIG_SYS_CLK_FREQ in U-Boot to the frequency you want. There CPU is first switched to alternate (slow) clock source and once main CPU clock is adjusted, it's switched back.

    You can try with (but no guarantee) in cpu0 node:
    assigned-clocks = <&ccu CLK_CPUX>; assigned-clock-rates = <1080000000>; Safe default is set in SPL (one of the first things that's is done).
    Note that everything is done by community without any plan. I just told you current pattern regarding these things. It could be that someone would prepare such patches soon or no one would find it interesting enough to work on it.

    Check ohci, ehci and usbphy nodes in my DT: https://github.com/jernejsk/linux-1/blob/h616-hdmi/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dts#L134 and https://github.com/jernejsk/linux-1/blob/h616-hdmi/arch/arm64/boot/dts/allwinner/sun50i-h616.dtsi. You should make a patch which adds these changes to DT, add patch to build system and build image. You can probably get away with making DT overlay too.
    Note that these are developer level instructions - I don't plan to write more detailed steps.

    that gets sorted out usually very late, when a lot of other features are already working.
     
    Those messages don't indicate alpha stage. Disabling just means that regulator was enabled at boot but Linux doesn't need it. "using dummy regulator" means that voltage regulator is not needed (vcc- regulators might get specified later but most of the time are not needed). syscon value message is imo useless and will probably get removed sooner or later.
    In short - several of these messages will probably stay in later, more complete kernel.

    It's possible to make it work if you enable all USB nodes in DT. It seems like some HW quirk.

    jernej got a reaction from P.P.A. in Understanding Hardware-Accelerated Video Decoding   
    This happens on all SoCs with DE2 or newer (A83t or newer SoC). Most SoCs have only one capable plane which can display YUV formats and it's always below current framebuffer, so that "workaround" (which imo is not workaround, but just part of configuration) is always needed in your use case. Note that having video plane below UI plane is actually desired for video players - UI plane has alpha channel which makes window with video transparent.

    Good summary, let me clear some things.
    Having proper uAPI by no means makes libva-v4l2-request obsolete. If this lib is updated to latest uAPI, it still could serve as intermediate layer for all apps that don't support new interface but they support VA-API.
    Before you talked about libva-v4l2-request, which implements VA-API, so I wouldn't say it's irrelevant to ARM HW accel. libvdpau-sunxi implements VDPAU, but that works only on BSP kernels and it is not relevant for mainline.
    Further clarification: Kodi 19.0 (released recently) is highly recommended for all this - it doesn't require any out of tree patch for video decoding (LE uses patch for HW deinterlacing). Additionally, with version 19.0, there is single binary for all 3 windowing systems (gbm, X11, wayland). Depends on build options. Not sure if this version is available on Armbian but PPA exists, so I guess it should not be hard to test.
    H264, MPEG2 and VP8 should be good in mainline, although api can still change until codec is promoted to uAPI. HEVC still needs out-of-tree patches for any serious work.
     
    Maybe you can update your text, so we have current state overview in single post.

    Yes, meson uses stateful whereas Cedrus and rkvdec use stateless (request api).
    Actually only one really worked on this driver but stopped working on most (all?) things due to real-life issues.
    Vanilla Kodi will work for video decoding, but if you want HW deinterlacing, that will need Kodi patch and additional one for ffmpeg.

    But as @Werner said, H616 is not exactly the same as H6 regarding display stuff so it needs quiet a lot of work. Cedrus will be probably easy, but that comes after display stack.

    jernej got a reaction from valant in HDMI output at u-boot load   
    @valantissue is more complicated than just some config option. Currently U-Boot doesn't support voltage regulators and rely on ATF to enable them (A64 has HDMI voltage supply pin). Logic in ATF will turn on all referenced voltage regulators, which is mostly fine. Issue is in word "mostly" - this logic will prevent ethernet PHY to power on correctly on OrangePi 3. Distros must decide what is lesser evil for time being, having no HDMI and ethernet in U-Boot or having no ethernet in Linux on OrangePi 3 (I didn't check what Armbian does exactly). Situation was discussed with maintainers and consensus is to implement voltage regulator driver in U-Boot, but that will take time. In the mean time, ATF could be updated with a improvement, which would temporary solve both situations, but I didn't find any patch for that yet.
