- Exynos 9820
- Exynos 9825
- For a new device open an issue and i will add it as soon as possible
- A simple app that can custom GPU frequency tables without recompiling the kernel
- By unpacking the DTB image, converting the dtb file to a dts file and editing the table, and finally repacking and flashing it.
- Install app on a exynos 9820/25 platform
- give su rights
- press edit gpu freq table
- select your chipset
- edit the table
- press save gpu freq table
- press repack and flash image (if u want to get safe press backup old image and follow the screen instructions)
- reboot and see if it works
- nobody knows it (yet)
- I will test it on a s10 5g
- dtc
- extract_dtb
- repack_dtb - Self crafted binary for attaching both dtb parts together and converting them to an image
- idk smasnungs kernel which prevents it from working (mostly)
- in the logs I found a pre defined table which freqs possible are
- i use a stock kernel but the overclock frequencies which i could achieve with a custom kernel were list 1:1 in the logs:

- basically these freqs work and no other ones
- these freqs are in the sram, so what i do is to create a custom kernel with a custom table, what i did and, but the voltages are linked to the frequencies even if you rewrite them
- so we need to trick out this mechanism --> The commit
- If there are any issues or whatever open an issue
- If you want to contribute open pull request
- for new device open issue with device, chipset name and android version
