Had been using this quite some time ago, it is sad that it has only 1-CPU support, preventing some SMP bugs from emerging. Wonder if it's hard to make it SMP, if too many places us…

Same here.

When would Apple silicons made natively support for OSes such as Linux? Apple seemlingly reluctant to release detailed technical reference manual for M-series SoCs, which makes run…

Reminds me of User Mode Linux, which AFAIK, runs only on Linux, maybe *nix.

Nope, mine runs on a native Linux box featuring Intel i7-1370P and 32GB RAM. Maybe Xilinx has some tuning which makes Yocto become slow at parsing the recipe dependency and the lik…

Your scenario makes me suspecting that it is Xilinx flavored Yocto causing the problem. I think that removing some unused Xilinx-specific layers/recipes can reduce the prologue and…

I was using Scarthgap (released April 2024), which is my first try. I realized the following: 1. Everytime a bb file is changed, it takes minutes to finish, for example, parsing re…

Got me wondering, how does it works?

PowerPC architecture, developed in late 1980s, was known for its performance for non-Intel processors in the 2000s. In real-time aspects, it outperforms Arm in that it provides com…

Out of curious, does BPF now capable of capturing all the context switch events such as CPU trap? Also, if the overhead is negligible, maybe the author can try to merge this into m…

In the near future, people can control appliances with purely their own consciousness, and the only prerequisite is that it requires a minimum consiciousness level, which is reacha…

If this is the case, it's weird then. Why releasing CPU for only a glimpse saves battery?

Sure, I'd try remove the app from the power efficiency restricted app list, which by default are enforced on all apps.

Yes, I was using Bluetooth headphones at the moment. I don't have the app name at hand, but I know that the app is also a file manager. So there's probably jitter in my headphones,…

Nope, mine is a playlist with only 3 local-stored tracks. Yes, I loop these 3 tracks all the time.

As computing power grows, smartphones should theoretically encounter fewer and fewer stutters. However, at least on the phones I've used, which are iPhone8 Plus and Pixel 7, stutte…

Is it then possible that one can "decorate" the elevator music? At least at a interference level. :p

If I want to porting it to x86_64, except the register width, what else do I mainly need to take care of? Thanks!

System76 recently announced their responsiveness optimizer, System76 Scheduler [0], which basically works as a daemon, adjusting the nice value and the CFS knobs for processes in t…

I don't think that the vanilla scheduler would get abandoned, instead, it would then acts as a fallback scheduler when customized userspace scheduler crashed or getting an update a…

The RFC patch [1] which introduces scheduler BPF into the Linux has been posted to the related mailing list (bpf and linux-kernel) two mounths ago. However, it has since only got a…

BTW, is there any recommended open source dynamic binary patching tool? Have been using Intel Pin, but fine-grained patches would incur noticeable performance regression permanentl…

But comes to C/P value, Intel is totally ruined.

I'm impressed. This should be awared when programming on embedded system.
