Anyone built linux 6.13 kernel with the RP patches?

Before I commit to a half day of building the 6.13 kernel, I don't suppose anyone has already built it for the 64bit raspberry pi os on the pi 5 that they'd be willing to share?

You can get the build from this PR https://github.com/raspberrypi/linux/pull/6626, which is a build from 2 days ago, with an outstanding DRM patch included.
Try running rpi-update pulls/6626 to install the kernel/dtbs/module built on that PR.

@mitu Ah thanks, that is good to know. But seems it doesn't have super pages enabled on that build, so I might just give it a shot and config it myself and see if it works.

If nothing else, it'll allow the system to switch to 4kb pages on the fly without having to change kernel to use aethersx2 or other abandoned applications in that situation

Edit: so I edited the above git pull to build with huge/super pages config on

I am noticing a slight increase in a few spots, for example I can push some of the flycast games up to a higher internal resolution. Not noticing too much change on the gamecube side of things, unless there's a game or two that runs at say 55fps or 27fps and it can be nudged into full speed.

So tried star fox adventures and it seems to goes from around 25fps in the area Fox first explores to a more manageable 47fps. With VI Skip on it becomes playable imo, if not at the original 60fps the game was at
