From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

been using Arch for years but i am still a novice, yesterday i had found that in order for something to work on my system i will need to edit a few lines in kernel which i did, then removed unnecessary modules > intel, > nvidia, compiled. it worked great but with Arch and its rolling release i am dreading the next update and having to go through this again.
what methods are there to automate this process?

set LINK_TRAINING_ATTEMPTS from 5 to 10 in drivers/gpu/drm/amd/display/dc/link/link_dpms.c and set LINK_TRAINING_RETRY_DELAY from 50 to 100 in drivers/gpu/drm/amd/display/dc/link/protocols/link_dp_training.c.

i doubt this will be added to kernel as its a fix for an issue that isn't wide spread.

That wouldn't be accepted as is, but those sound like tunables. They could be exposed as kernel parameters. May be worth submitting the patch as an RFC just to call attention to it.

I followed your advice, Github my edit link_dpms.c, - Github my edit link_dp_training.c how do i submit as RFC. total noob with github lol.

Successful GitHub pulls are rare; more often, patches live like this. You're better off contacting the maintainer of the subsystem you're editing. See the official submission guide.
