Having had to deal with those exact same issues & not finding references to compare my solution against has always left a sour taste. If you ever decide to go forward with it let me know, happy to review it if it helps you.

Absolutely. For whatever it is worth, perhaps consider submitting it to one of Europe's conferences like Digital Dragons/etc
Efficient & effective SDR UI playing nice with HDR rendering and/or HDR display output is such a difficult thing to get right without destroying artistic intent.

Oh that would be such a cool topic for a talk! There's very few talks on that subject and everyone ends up finding their own ways of reinventing the wheel again and again.
Not only that but things like how to establish a great pipeline for artists to author UIs in HDR could be invaluable

Here’s an interesting new JCGT paper showing that small neural nets can outperform LUTs in speed/memory/accuracy even when embedded in purely CPU-based renderers. The authors are some ex-Pixar rendering guys who are now at Aurora.

From profiling to kernel patch: the journey to an eBPF performance fix | Ritesh Oedayrajsingh Varma A story about how an innocent profiling session led to a change to the Linux kernel that makes eBPF map-in-map updates much faster.

New article! What do you do when profiling your code shows the slowdown isn't in your code, but deep in the kernel? Why, you grab the kernel source and go spelunking.

How a routine profiling session turned into a Linux kernel patch: rovarma.com/articles/fro...

I guess I misunderstood the assignment when I was asked for a "sheep" Fresnel? 🤔

Optimizing libdwarf .eh_frame enumeration | Ritesh Oedayrajsingh Varma For the Linux version of Superluminal we rely on unwind information stored in the .eh_frame section in a binary to perform stack unwinding. We’ll go over optimizations we made to libdwarf that greatly...

I've been wanting to start a blog for a while, and finally decided to bite the bullet.

The first article of hopefully many more to come is about, you guessed it, profiling & optimization.
