According to the devs they gave this answer:

Multithreading will only show speedups on much larger designs. In small designs the communication between cores will be much larger than leaving it on one core.

So it seems that the initial guesses were correct, and the code in question is not sufficient to exhibit a speedup. The overhead involved is to high so that it doesn't benefit from multithreading.

Not knowing what process you have followed so far, I found two resources that may be helpful here for you..

This comment from yu3fms on a GitHub repo about QEMU on M1 discusses using brew for ARM and specific patches for QEMU to enable vhf acceleration.

And this Syonyk's Project Blog post, The Apple M1, ARM/x86 Linux Virtualization, and BOINC is a great tutorial on how to get QEMU up and running on an M1 Mac for both ARM and x86 guests.

I've been having the same issue as well. The only way I found to fix it is to roll back to the 5.6.0-1042-oem kernel. The AMD drivers don't seem to support any kernel past this one.

Edit: This is also a way to get the amdgpupro drivers to install without a problem.

WARNING: I'm writing all this after the fact and i might have missed a step or something along the way. Please be very careful especially with trying to remove kernels and when working in your boot directory. If you're uncomfortable with the idea of wrecking your system you can always set grub's default selection which is a lot safer than removing an initramfs.

Here's how I got RocM working

It looks like this CPU does not have an integrated GPU.

Exactly as mentioned in the comments, it is an emulation on vm that Jupyter uses, so hardware rendering is not possible.

Your code panics because as_str() only returns Some, if there is no arguments. So when you immediately unwrap() it will panic, for instances where you have arguments to be formatted.

Get the formatted string, if it has no arguments to be formatted.

This can be used to avoid allocations in the most trivial case.

– std::fmt::Arguments::as_str() docs

Instead you can use args.to_string() instead of args.as_str().unwrap(), to format it into a String. So it actually formats regardless of whether there is any arguments or not.

I tried to read videomemory in graphic mode 13h (320*200px) with TurboDebugger in DOSBox on 64bit Windows and it worked as expected: REPE SCASB stopped with DI=0143h and the value loaded by
MOV AL,[ES:DI-1] was 2.
The first pixel line at ES:0 (140h bytes) is all 0 (black), the second line starts at ES:0140h with two black pixels (0 bytes), followed by the byte with value AL=2 (blue), which is the tip of capital letter A glyph.

However the videomemory cannot be inspected using Alt-F5 to switch between TurboDebugger user-screen and CPU window) due to imperfection of debugger and DOSBox emulation. The situation is even more complicated with planar graphic modes 0Dh, 0Eh, 12h. VGA maps all four memory planes (pages) at the same linear address A0000h and you would have to select the page first by direct output to CRT ports (see the link in @fuz first comment). You may want to load the nonzero byte from videoram and print it with INT 10h instead of hlt, just to assure that it's there.

I remember how I debugged my graphic program some 30 years ago with two DOS computers connected by serial ports, using Borland TD.EXE and TDREMOTE.EXE. I was able to step through instructions which wrote to EGA/VGA CRT registers and to watch the effects without having to switch between debugger window and user screen.

I'm not sure what do you want to achieve but in nonemulated DOS with graphic mode 13h you might succeed.

Found the answer

The problem is that there are not enough cells in this FPGA for that amount of memory. If you encode only reading from memory, then the synthesizer will not create the required number of links and this will not cause an error. If you encode both reading and writing, then only then the synthesizer will create all the memory cells. For Altera MAX II in reality, you can create about 16 kilobytes.
