Best cheap board for trying RISCV
Any good and cheap board for mess around with? Currently I'm thinking about getting the MILK-V Duo S, is it good?

Confidential computing for embedded RISC-V runs now on HiFive P550 evaluation board
Assured confidential execution (ACE) implements VM-based trusted execution environment (TEE) for embedded RISC-V systems with focus on a formally verified and auditable firmware. For evaluation purposes, it runs now on the first RISC-V hardware supporting virtualization (RISC-V H extension): HiFive Premier P550 from SiFive.

Query regarding Quick Access Command in Riscv-Debug-Specification
Hi everyone, i am trying to implement debug module on my core and i have a query regarding abstract command from riscv-debug-specification, now according to the specification quick access allows program buffer to execute command when the core is halted and if not halted cmderr writes 4 now cmderr is a r/W1C type which means read/write and write 1 to clear, it is a special type of field that on writing 1 it clears that bit, now lets suppose cmderr is initially clear i.e; (000) and i am to write 4 i.e; (100). Now instead of writing 4 would it not remain same as initial condition? and if so then how would cmderr set its state to (halt/resume) 4? Would highly appreciate if anyone can let me know.

Best input board for running OS?
Hello everyone!
I am looking for an entry-level RISC-V-based SBC that is capable of running a full operating system with good CPU and GPU performance. So far, I have considered the following options:
SiFive VisionFive 2
M!lk-V Meles
M!lk-V Mars
Do you know of any other alternatives that provide a good balance between processing performance and graphics capabilities? My goal is to use the board for software testing and light applications, but I would like to have a decent GPU for basic graphics applications (e.g. running a Linux desktop environment or GUI projects).
What boards do you recommend? Are there any recent RISC-V releases that are worth evaluating for this purpose?
I would appreciate any suggestions or user experience!

RISC-V multiplying without a multiplier
I learned so much last time I posted code here (still updating my rvint library with the code reviews I got), I thought I’d do it again.
I’ve attempted to come up with the optimum instruction sequences for multiplying by small constants in the range 0-256:
https://needlesscomplexity.substack.com/p/how-many-more-times
Have shorter sequences? I’d love to see them! I only used add, sub, and << operations in mine.

Milk-V Megrez experiences and two little things...
Hi @ all!
I just wanted to write an update, also because there is hardly any experience with this board.
I've actually managed to create a halfway functional desktop PC out of my Milk-V Megrez, and it's starting to really start to feel like I can use it for various things.
The Fedora image destroys the U-Boot. It took me ages to reset the program using an old external hard drive. I don't seem to be the only one having this problem, so I advise against using this image.
RockOS is a bit tricky, especially if you're not too familiar with the software, but it's definitely customizable.
However, I removed the preinstalled Lightdm, because it was causing problems with my GPU (AMD Radeon RX 6400). Logging in via the console (startx command) isn't a problem, so I don't need this login manager anyway.
The GPU itself is recognized, as far as I can see, but this always varies depending on the program. With SuperTuxKart, I see a significant graphical improvement. Other programs, like Neverput, don't work. A bit strange to me, but I can life without this. Don't know if I need some other packages that I can't find.
My two monitors work without any restrictions. I use one with HDMI and one with DisplayPort. With the default XFCE Desktop, I occasionally have trouble detecting both, or it seems to get confused with the DisplayPort from time to time. I don't know if this is due to some settings, because I haven't this problem if I use KDE. It's works very well.
Gnome seems incredibly slow to me, especially when I compare it to the Raspberry Pi desktop. I don't know why, but even on the Raspberry Pi, I don't think the performance is particularly good.
For some time, no QT applications were running. This was because a package called "QT base development files - OpenGL ES variant" was missing or had been deleted somewhere while installing other applications.
The sound was a bit choppy at first, but that's entirely due to the pre-installed Pulseaudio. It works better when the sound is output via the GPU, but I would still replace Pulseaudio with Pipewire. Pipewire works perfectly and has no interference.
For my Wi-Fi connection, I use a TP-Link Archer T2U Plus AC600. The required packages were easy to install, so it works really reliably.
I actually only have two problems that bother me.
1. Unlike the regular applications themselves, which run fairly smoothly, web browsers perform terribly. Performance is very slow, especially when loading larger web pages. Firefox and Chromium can't use WebGL, while Ephipany does, albeit with rather poor benchmarks. With 500 Fishes I have only 30FPS. I know that it must be better.
2. I also wanted to use Bluetooth over USB, so I bought a TP Link UB500 Nano. While the Wi-Fi dongle didn't cause any problems after installing the packages, this dongle unfortunately didn't work at all. It recognizes the dongle, but can't actually read it. I've installed the bluez packages and the corresponding realtek firmware. I don't know if I'm missing something or if it's the dongle itself.
I am grateful for any ideas.\^\^)

We already had default repositories for amd64, arm64, but now, there's also RiscV64, and while it still doesn't catch up to the 4145 binaries in the amd64 repo, or the 3920 binaries in the arm64 repo, after just a few days of having been added, the RiscV64 harbors 569 binaries, and that number is still rapidly growing
I would like to know what the community thinks :)
