Whenever I hear an autistic person say "ok, so" during a conversation, I get very happy, as I am about to learn an entire semester's worth of information in the next 15 minutes.
The most wonderful phrase.

@TakeV you dont get to call me out like this

@TakeV 6 months really gives ypu so mich how much time is wasted in learning through pfixial mens

@TakeV ok so, the SGX series5 driver stack-

@TakeV eepy girl, will tomorrow

@TakeV ok let's do this

@TakeV so you have a few components:

- libsrv_init, which loads the operating system for the gpu, which of course is a thing, it does a bunch of allocations for both instruction sets the gpu supports, patches some addresses around, builds a "script" and sends the script off to the kernel to be executed to get the gpu running

- libsrv_um, which would be like libdrm(vendor) in a modern linux system, except it also implements a bunch of random large abstractions over kernel functions, including an abstraction of a "kick" that is really complicated and shuffles around massive amounts of data, this library owns the large amount of chunks of gpu memory for reasons i do not yet quite understand, and a lot of them are filled with garbage

and after this you have your actual opengl libraries, which among other things use a few others like the glsl compiler

in general it's not utterly terrible but it could be quite a bit better

@TakeV there's a lot more that's fucked about these and i have a whole blog post about my initial reverse engineering findings
