KDiskMark VS freedesktop-sdk

Hi So yeah, ithttps://github.com/JonMagon/KDiskMark/

``` KDiskMark (3.1.2): https://github.com/JonMagon/KDiskMark

I'd recommend doing a speedtest on your MicroSD using https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2 just to be sure your card is genuine and performing to spec.

But the theoretical write speeds definitely do not apply when it comes to the steam deck, you have an adequate card but I advise you do a speed test in desktop mode using https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2 to double check the actual speed you're getting, it'll likely equate to no more than 80mb/s write which is most definitely not enough to handle download speeds of 70MB/s considering steam unpacks as it downloads.

Since owners of this MicroSD card are few and far between, would you mind testing its speed and performance for me, using KDiskMark? You can download the program from here: https://github.com/JonMagon/KDiskMark/releases/tag/3.1.2

Hopefully that provides an insight into why 'U3 A2 UHS-I' is the ideal card you should be looking for with the deck. I would always recommend when you purchase a new card that you run 'Kdiskmark' in desktop mode by downloading it from here: https://github.com/JonMagon/KDiskMark/releases Check the latest release and download the file ending in 'appimage'. From here open the folder it downloaded to, (don't open it from Firefox as it won't know what to do with the file) double click the file and should open the Kdiskmark window. From here you can select your MicroSD card and do a speed test to make sure you are hitting the advertised speeds!

I'd recommend you download kdiskmark from here: https://github.com/JonMagon/KDiskMark/releases/tag/3.0.0 (Download the one ending in appimage as it doesn't need an install)

Try testing your speeds with kdiskmark

I think I might have confused two unrelated posts. The one that references Polar Signals is this one:

https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/...

So not a perf issue there, but they don't think the workflow is suitable for whole-system profiling. Perf issues were in the context of `perf` using DWARF:

https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/...

But the fd-sdk https://gitlab.com/freedesktop-sdk/freedesktop-sdk and gnome build meta https://gitlab.gnome.org/GNOME/gnome-build-meta projects can prove as good references.

With all of these hypothetical features out of the way and looking just at current release software, Flatpak allows you to do so much stuff that isn't accessible for a not-so-techy user. Custom installation folder? Yep. Running mesa-git GPU drivers? You got it. Any way to easily do this via GUI? In typical Linux fashion, nope. For a GUI focused packaging format this is a big letdown.

You can load up Mesa GIT using environment variables, see here. Honestly what I miss the most from flatpak Steam is properly working non-Steam shortcuts, but I've given up on that.

It was my understanding that the packages for vaapi are just put into the -extra version of the sdk so app maintainers can opt out, but they are still available if they want to use them. See https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/merge_requests/10616
