Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Dell XPS 15 9520 (64GB RAM): How much battery drainage in percentage are you getting when your laptop is in Sleep/Standby/Suspend mode (powering the memory)? In my case is around 1% / hour using Debian 12, that means the laptop will not last more than 2-3 days
soon? https://github.com/intel/linux-intel-lts/issues/33

The Great CPU Stagnation
There’s actually 2, theres the intel lts one, which i guess they did do something it just never amounted to anything, explained here:

No kernel support yet, see this GitHub issue for updates.

Intel's new GPUs, dream for vfio setups?
Intel has SR-IOV support on their own branch of the LTS kernel. I made an issue asking when they would mainline it, hopefully they do it next year.
- Intel 12th gen full iGPU passthrough to Linux guest, is it possible?

No SR-IOV for ARC A-series GPUs?
SR-IOV is working on gen12 in Intel's kernel fork here: https://github.com/intel/linux-intel-lts/blob/lts-v5.10.120-yocto-220627T062711Z/drivers/gpu/drm/i915/i915_sriov.c

SR-IOV of Intel GPU seems to be available, and the work of merging the code into the mainline kernel is in progress.
https://github.com/intel/linux-intel-lts/issues/33#issuecomment-1176996341 SR-IOV of Intel GPU seems to be available, and the work of merging the code into the mainline kernel is in progress. https://github.com/intel/linux-intel-lts/blob/lts-v5.10.120-yocto-220627T062711Z/drivers/gpu/drm/i915/i915_sriov.c I did find the relevant code of SR-IOV in this repository, but the kernel version is a little old. Maybe it can be ported to the mainline kernel through DKMS or patches? After all, code consolidation may not be completed until the end of 2023.

GVM: A GPU Virtual Machine for Iommu-Capable Computers
>> https://github.com/intel/linux-intel-lts/commit/41ef979f0894
> This is pretty unhelpful. Legitimately
Indeed, "98 changed files with 11,276 additions and 46 deletions" and no idea if it will work on a vanilla kernel.
I would like to try running linux baremetal to virtualize Windows 11 running in fullscreen mode with control over the mouse and keyboard, but I may wait until that's mainlined.

QEMU AioContext removal and how it was done
https://gitlab.com/qemu-project/qemu/-/blob/master/hw/scsi/s...
QEMU's IOThreads allow the user to configure the threads and get something similar to thread per core architecture. But if 1 thread becomes a bottleneck, then some form of thread synchronization is needed again even with thread per core architecture. Some problems can be parallelized and they work well with thread per core.

Why are Apple Silicon VMs so different?
Add `ENV ERL_FLAGS="+JPperf true"` to your Dockerfile and it will build just fine cross platform. The flag just changes some things during build time and won’t affect runtime performance.

RISC-V Vector benchmark results
> I don't know how rdcycle works on qemu.
That's a good question! I had to look it up myself ...
Obviously qemu TCG isn't a cycle-accurate emulation. Using RDCYCLE / reading the corresponding CSR eventually calls https://gitlab.com/qemu-project/qemu/-/blob/69680740eafa1838... which calls cpu_get_host_ticks is basically an arch-independent wrapper around RDTSC.
So it just measures the time taken to run using RDTSC. Which I guess is what you would want (maybe?). It would measure the time taken to emulate the vector instruction in host instructions.
> This benchmark is more meant for developers to figure out how to vectorize algorithms effectively, as in which instructions to choose.
Absolutely, I'm not saying the qemu results would say anything very deep, but they're kind of interesting from the point of view of either optimizing qemu or if you have to use qemu because the hardware you want isn't available / isn't cheap enough.

The IMPOSSIBLE RISCV HACK: Vector Extension 0.7.1-draft w/ current Linux kernel! – René Rebe

I booted Linux 292,612 times
>> https://gitlab.com/qemu-project/qemu/-/issues/1696 ]
> Can I please just get the detail in mail instead of having to go look at random websites?
Maybe it's me but if I did boot boot linux 292.612 times to find a bug, you might as well click a link to a repository of a major open source project on a major git hosting service.
Is it really that weird to ask people online to check a website? Maybe I don't know the etiquette of these mail lists so this is a geniune question.

Rise: Accelerate the Development of Open Source Software for RISC-V
Capstone is used[1] by QEMU as disassembly engine in debug logs and in monitor mode debugger, by the way, so it's in the scope of the RISE effort.

Intel Arc 750 Crashes Host + Display Cable Workaround not needed anymore (Windows)
A user on the qemu bugtracker found a way to get the Intel Arc working across resets without crashing the host: Just don't passthrough the audio device of the GPU and everything works!
- Qemu 7.2.2: command line syntax in libvirt domain changed
