Linux/ELF .eh_frame from the bottom up
Linux uses the sysv calling convention. I believe these are the official or semi-official documents for x86 64-bit and 32-bit, respectively:

Six Great Features with the Upcoming Linux 6.6 Kernel
ABI is just the name for any stable binary interface between parts of a program, eg in C there is a well-defined ABI for calling functions: https://gitlab.com/x86-psABIs/x86-64-ABI/-/jobs/artifacts/ma... https://www.agner.org/optimize/calling_conventions.pdf
If you combine that with a stable set of C function names and parameters, then you could define an ABI for kernel modules if you (and the Linux developers) wanted. While it sounds like a good idea, the outcome probably wouldn't be great for users.

Does C++ have a stable ABI or not?
But in the same breath, that paragraph's footnote points directly to the Itanium C++ ABI specification which seems to do precisely what they said has never been done. (I've filed a bug...).

What x64 ABI does linux / GCC ACTUALLY use?
The supposed latest psABI specs (https://gitlab.com/x86-psABIs/x86-64-ABI) contain the following, with regards to classifying aggregates for argument passing (section 3.2.3, page 24, of the AMD64 ABI 1.0 – December 6, 2022 specs):

Change default CPU type?
RHEL, from version 9, requires x86-64 v2. The levels are a common effort between several companies, AMD included. The definitions can be found in this repo, and here is the latest PDF.

System V Application Binary Interface [pdf]
Note that this isn't the most up-to-date version of the x86-64 SysV ABI--if you want that, go to https://gitlab.com/x86-psABIs/x86-64-ABI/-/jobs/artifacts/ma... .
Although I think the only updates since the version linked here are effectively editorial in note. The last big updates are adding AMX registers to the ABI, and the addition of microarchitecture levels, both of which are in this version.

Attempts to write to VBE framebuffer either cause QEMU bootlooping or do nothing.
As far as calling conventions go, it's explained very thoroughly in the AMD64 psABI. I know it's not the easiest read, but it does say that the first integer parameter is passed in RDI.
