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.

Fedora - changes in pp_table don't persist after restart (lemmy.world)

Hello,

I'm adjusting pp_table settings to get most out of my GPU (RX 6800 XT) and it works but every time I restart PC the changes revert back to default. Any idea how I could make them persist?

For me pp_table is located in /sys/class/drm/card1/device/pp_table

I have to use chmod to be able to make changes:

sudo chmod o+w /sys/class/drm/card1/device/pp_table

Then I'm able to write in changes with upp:

upp -p /sys/class/drm/card1/device/pp_table set --write smc_pptable/SocketPowerLimitAc/0=312 smc_pptable/SocketPowerLimitDc/0=293 smc_pptable/TdcLimit/0=300 smc_pptable/FreqTableSocclk/1=1350 smc_pptable/FreqTableFclk/1=2000 smc_pptable/FclkBoostFreq=2000

And just in case you're wondering if the effort even makes sene, yes it does:

Max OC with LACT with max default limits (left) vs max OC with edited pp_table (right) in the picture.

Use triple backticks for blocks of code-type stuff

```

like so
