July 7, 20233 yr @balbes150, thank you for your incredible work on these RISC-V builds. I am using the nezha 20230630-current sid image on my Mango Pi MQ-Pro and it works well. However there seems to be no vector extension (RVV) support. This makes sense because the vector support in the kernel is not yet included mainline (not even 6.4) as far as I can tell. Although @msomeone previously reported RVV support in 6.1.0-rc3 and I am curious how that was accomplished. In any case my `/proc/cpuinfo` does not report the V extension. $ cat /proc/cpuinfo processor : 0 hart : 0 isa : rv64imafdc mmu : sv39 uarch : thead,c906 mvendorid : 0x5b7 marchid : 0x0 mimpid : 0x0 $ uname -a Linux chiyu 6.1.0-rc3-d1 #23.06 Fri Jun 30 21:26:26 MSK 2023 riscv64 GNU/Linux And attempting to run a test program (something like this) that contains a vector instruction will trap and halt the program. Program received signal SIGILL, Illegal instruction. add_data_vec_8 () at test.S:9 9 vsetvli t0, a3, e8,m1 # Vectors of 8b I would like some more information about enabling RVV on these boards, if that is possible. I could rebuild my kernel from the master branch using the config in `/boot` (plus enabling the RVV kernel config params), but I don't know if that would get me anywhere.

July 10, 20233 yr I went and recompiled the kernel from master using the existing configuration file, `make menuconfig` to turn on the RVV-related params, `make` and then `make bindeb-pkg` to generate dpkg archives. But no luck - installing the packages prevented my Mango Pi from booting so I'm on my backup SD card. I'm not able to connect to uart0 either, so I'm rather in the dark on what is going wrong during the boot process. I'll leave my modified kernel config file here for anyone who's interested, and keep experimenting with kernel builds. config-6.4.0+
July 10, 20233 yr @wba did you read & watch It seems like a big task. But what can I say: that youtube video was already too complicated for me. Other posts https://www.reddit.com/r/RISCV/new/ seem to indicate it also involves the compiler and other tools Edited July 10, 20233 yr by Superkoning

Other posts https://www.reddit.com/r/RISCV/new/ seem to indicate it also involves the compiler and other tools Thanks. No, I didn't see that before. Having watched a bit of it, now I understand that there is a difference between the vector ISA extension implemented by the T-head core inside the D1 (0.7.1-draft) and the vector ISA extension targeted by the mainline kernel (1.0.0). I failed to catch this up until now. Well, it's not mentioned anywhere on the linux-sunxi wiki page for the D1, which is odd. But now looking through the comments on Reddit and Youtube and some kernel mailing list threads etc. I see that there has been an ongoing discussion about this for a while. In any case, of course this means that just compiling a mainline kernel with RVV support flags enabled won't make vector work on my Mango Pi MQ-Pro. Also, it won't do to use any random test program for RVV to test the D1's vector instructions, since those are likely to target the 1.0.0 spec as well. It looks like there are some demo programs that target the spec implemented by T-head specifically (xuantie-vector-demos), so I will try with those instead. But I don't expect to make much progress in light of this...
July 10, 20233 yr Yes, RVV 0.7.1 versus RVV 1.0. Enabling RVV 0.7.1 seems like a minefield / swamp. With a lot of tools that need to be enabled for RVV 0.7.1, and the powers that be are not in favour of that. On https://www.reddit.com/r/RISCV/new/ follow the wise but sobering words of Bruce Hoult.
September 15, 20233 yr Hey Balbes none of the 6.5.0 Images work. Only those of the 5.19 kernel do. This has been getting updates and updates but... we are way stuck behind..

September 17, 20233 yr Author Ver 20230917-edge kernel 6.6.-rc1 for Nezha (Allwinner D1) (HDMI not work)
October 1, 20233 yr Author Version 20230930-current for Nezha and other models based on Allwinner D1. U-boot has changed. Added support for direct system startup from USB. This will make it easy to run additional systems without changing the SD card, simply by connecting a USB flash drive with the new system. Launch from USB on Nezha and Mangope MQ Pro models has been tested. On theLicheRVr model, the USB flash drive has not been determined, perhaps another USB flash drive model is needed.

November 2, 20232 yr Author This branch is outdated and has not been updated for a long time. What do you want to assemble (what is missing in the latest images 20230930 for this model)?
November 2, 20232 yr I would like to master embedded linux and learn how to collect images, specifically in version 20230930 I can’t enable uart through the dts file and I decided that it would be more correct to add the image in the assembly, but the image is not assembled without changes. (I apologize for my English, I'm using a translator)

January 4, 20242 yr The latest current nezha d1 debian version (20230930) refuses to boot (or does not display anything through hdmi) after a system upgrade on the lichee rv dock
February 4, 20242 yr Hi there, just to clarify; all of you having wlan0 up and running, are you using an USB adapter or the RVdock built in wifi chip I'min the same situation as noticed here: I'm using 23_09_sid_edge_6.6.0, and gotsame problem with current 6.1 -------------EDIT---------------- Got it working finally. For any unknow reason, the arbiam setup script at first boot didn't finished totaly. I have burned a new SD card with 23_09_sid_edge_6.6.0 and everything (at least Wifi) is fine. Thank you @balbes150 great job Edited February 4, 20242 yr by le51

May 28, 20242 yr balbes150, There is something wrong with performance. I am trying "Armbian_23.09_Nezha_sid_current_6.1.0_xfce_desktop.img.xz" Doing my simplest performance test: dd if=/dev/zero bs=1M count=256 | md5sum The result is 21 MB/sec. Moving windows in Xfce is really sluggish, even after disabling compositor, leaves trail on screen and lags behind mouse movement. Compared to "licheerv-debian-clean-hdmi.zst" from https://linux-sunxi.org/Sipeed_Lichee_RV#Pre-made_images (last in the list). Using kernel 5.18. The same benchmark returns 51 MB/sec. Moving windows is very responsive. Edited May 28, 20242 yr by rm_
May 28, 20242 yr Tried "Armbian_22.08.0-trunk_Nezha_sid_current_5.19.0_xfce_desktop.img.xz", the result there is much better, 49 MB/sec. But the WiFi onboard of LicheeRV Dock is not detected.
