SMT and CPU Boost Options

[cerdafyed]

CPU Boost and SMT option toggles were removed, is this permanent? Turning off SMT increased performance for certain emulators, and the official PowerTools app doesn't play well with non-steam deck devices like this plug-in does

Regarding SMT, currently there's a bug where disabling SMT prevents the plugin from being able to manage power governors and energy profiles.

most SMT-related bugs with emulators were fixed on Linux kernel version v6.1, so I deemed it safe to remove SMT control.

CPU boost will depend on your scaling-driver, which you'll see listed at the bottom of the plugin.

If you are willing to permanently change your scaling driver from amd-pstate-epp to amd-pstate, the cpu boost toggle will show up again. But you'll no longer have access to the Energy Performance Preference options while using regular amd-pstate instead of amd-pstate-epp

Note that if I see an opportunity to re-add the functionality back on future updates, and bugs are resolved, I will try to re-add the functionality.

For CPU boost, it'll probably require this in a future kernel update: https://www.phoronix.com/news/AMD-Core-Perf-Boost-Linux

SMT toggle has been fixed + re-added as of v0.2.3

re-adding CPU boost will be re-visited once the changes are on kernel 6.9: https://www.phoronix.com/news/AMD-Core-Perf-Boost-Linux

Note that the CPU Boost toggle is still actually available in the plugin for scaling drivers amd-pstate and acpi-cpufreq, just not amd-pstate-epp
