Hi Jernej. I have some questions about allwinner H6 and h616 HW decoding. I searched around and found out the H6 SOC's have a second VPU that uses the hantro-vpu decoder for VP9. video-codec-g2@1c00000 { compatible = "allwinner,sun50i-h6-vpu-g2"; reg = <0x01c00000 0x1000>; interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_HIGH>; clocks = <&ccu CLK_BUS_VP9>, <&ccu CLK_VP9>; clock-names = "bus", "mod"; resets = <&ccu RST_BUS_VP9>; iommus = <&iommu 5>; }; I couldn't find these CLK_BUS_VP9 and CLK_VP9 clocks in the H616/618 manuals. I guess allwinner took away this secondary vpu? Do we need to patch cedrus to include VP9 support? Trying to get HW decoding to work on chromium.

I think only the H6 SoC has a second VPU. This second VPU uses the hantro-vpu decoder for VP9. So this should work on H6.

I was looking at the v4l2 patches for chromium. I think we can apply this to cedrus. First, we apply these two patches. https://github.com/armbian/build/blob/f55a87d469b0634f72bc857f773a52a466f66292/patch/kernel/archive/rockchip64-6.6/media-0001-dma-mapping-let-dma_alloc_noncontiguous-allow-DMA_AT.patch https://github.com/armbian/build/blob/f55a87d469b0634f72bc857f773a52a466f66292/patch/kernel/archive/rockchip64-6.6/media-0002-Enable-non-coherent-dst-bufs-for-Hantro-V4L2-driver.patch For the last patch we replace it with our own by editing /drivers/staging/media/sunxi/cedrus/cedrus_video.c and adding "dst_vq->allow_cache_hints = 1;". You will see it at the very bottom of the cedrus_video.c file. https://github.com/armbian/build/blob/f55a87d469b0634f72bc857f773a52a466f66292/patch/kernel/archive/rockchip64-6.6/media-0003-Enable-non-coherent-dst-bufs-for-Rkvdec-V4L2-driver.patch From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: amazingfate <liujianfeng1994@gmail.com> Date: Fri, 3 Nov 2023 18:07:24 +0800 Subject: Enable non-coherent dst bufs for Rkvdec V4L2 driver --- drivers/staging/media/rkvdec/rkvdec.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/staging/media/rkvdec/rkvdec.c b/drivers/staging/media/rkvdec/rkvdec.c index 84a41792cb4b..b35f7e1b8a20 100644 --- a/drivers/staging/media/rkvdec/rkvdec.c +++ b/drivers/staging/media/rkvdec/rkvdec.c @@ -755,6 +755,7 @@ static int rkvdec_queue_init(void *priv, dst_vq->timestamp_flags = V4L2_BUF_FLAG_TIMESTAMP_COPY; dst_vq->lock = &rkvdec->vdev_lock; dst_vq->dev = rkvdec->v4l2_dev.dev; + dst_vq->allow_cache_hints = 1; return vb2_queue_init(dst_vq); } -- Armbian https://github.com/torvalds/linux/blob/master/drivers/staging/media/sunxi/cedrus/cedrus_video.c dst_vq->dev = ctx->dev->dev; dst_vq->allow_cache_hints = 1; return vb2_queue_init(dst_vq); } https://github.com/armbian/build/pull/5883 Then we have to create our own udev rules.

Yes, you need it.

Javad, Have you patched your u-boot? You need these three patch files. https://github.com/NickAlilovhttps://github.com/NickAlilovic/build/blob/v20241125/patch/u-boot/u-boot-sunxi/106-Add-int-phy-eth-H313-h616-with-AC300.patch https://github.com/NickAlilovic/build/blob/v20241125/patch/u-boot/u-boot-sunxi/106-Add-int-phy-eth-H313-h616-with-AC300.patch https://github.com/NickAlilovic/build/blob/v20241125/patch/u-boot/u-boot-sunxi/dts-Transpeed-8K618-T-Enable-Ethernet.patch For your custom Kernel you need https://github.com/NickAlilovic/build/blob/v20241125/patch/kernel/archive/sunxi-6.10/patches.armbian/arm64-dts-allwinner-h618-add-Transpeed-8K618-T-support.patch The last two patches adds this to your u-boot and kernel DTS. aliases { ethernet0 = &emac1; ethernet1 = &sdio_wifi; serial0 = &uart0; }; &emac1 { pinctrl-names = "default"; pinctrl-0 = <&rmii_pins>; phy-mode = "rmii"; phy-handle = <&rmii_phy>; phy-supply = <&reg_aldo1>; allwinner,rx-delay-ps = <3100>; allwinner,tx-delay-ps = <700>; status = "okay"; }; &mdio1 { rmii_phy: ethernet-phy@0 { compatible = "ethernet-phy-ieee802.3-c22"; reg = <0>; }; }; You already have the EPHY 200 patched in your kernel. You have to edit your kernel config to enable it. # # MII PHY device drivers # CONFIG_AC200_PHY=m # # Multifunction device drivers # CONFIG_MFD_AC200=m # # PHY Subsystem # CONFIG_AC200_PHY_CTL=m

Reinaldo if you want to modify the android kernel visit the XDA forums. Android uses an old linux kernel with Board Support Package (BSP) provided by Allwinner. Armbian build uses the mainline linux kernel with patches. No support from Allwinner. Just a few hackers that reversed engineered and back port sources from the BSP kernel.

Remember you have a custom kernel. You need to block kernel updates with the armbian config tool.

@UnhealthyTweak that's the thing about these TVBoxs.. It's community supported. Unless someone has the same box as yours and releases the image. You might be waiting forever. I have a transpeed 8K618-T and even this box has more than one wifi/bluetooth chip. Usually it's a broadcom wifi chip and only needs firmware changes. Some boxes need a patch to include the firmware like broadcom 43342. Your box has a different wifi chip. https://github.com/LYU4662/t95zplus-h618-build/tree/master/userpatches/kernel/archive/sunxi-6.7 Try this image.. if it doesn't work it might be the GPIO # that's different. You would need to extract your gpio # from the orignal android DTS.

aw869a chip uses the aic8800 firmware. The drivers are old but have been ported to newer kernel. You can find patches here. https://github.com/LYU4662/t95zplus-h618-build/tree/master/userpatches/kernel/archive/sunxi-6.7 For internal storage not working, You need to extract your dts and find the correct gpio settings. USB2 probably needs to be enable in the DTS. IR not working. There are posts a few pages back that enables IR.

If you are just editing a dts there's a way to compile a new dtb and replace the one in your sdcard. https://stackoverflow.com/questions/21670967/how-to-compile-dts-linux-device-tree-source-files-to-dtb If you are editing more than a dts. You can compile the Armbian kernel with all the patches applied. Go into the cache folder and edit the kernel sources. Then compile the kernel manually. When done replace your kernel binary and modules in your SD card.

when i create my patches they are nothing like the ones that Nick provided me. (patches to add tanix-tx6s-axp313.dts to uboot and kernel) If you can post your patches... I can tell you where you went wrong. I use xfce desktop. To get line out working I have to manually switch it in the pulse audio settings menu. I don't use KERNEL_GIT=shallow option. Not sure if you are having issues using this option. I would avoid it for now. bluetooth and video acceleration is still a work in progress. For bluetooth try these instructions from afiftyp For video acceleration using v4l2 Video acceleration in chromium (It looks like we need to add "allow_cache_hints = 1;" to the pitfrost driver. Not sure what else needs changes.) https://github.com/armbian/build/pull/5883 https://github.com/armbian/build/commit/f55a87d469b0634f72bc857f773a52a466f66292 https://github.com/amazingfate/chromium-libv4l2-patches https://github.com/saiarcot895/chromium-ubuntu-build/issues/65 I haven't had time to test these patches.

It's there. You just need to remove the "+". I used this shell script command. Editing it by hand would take forever.

What you are referring as "android" dts is nothing more than a device tree wrote for a very old Linux kernel (probably 3.10 or 3.14). As long as things change during time, so the device tree specifications become more standardized and well-defined. Device trees for old kernels (3.10 is very old nowadyas) are very messy and generally harder to read and understand.
