AMD makes another attempt to enable FreeSync by default in the Linux kernel.
AMD is providing a new FreeSync driver to the Linux kernel in an attempt to enable FreeSync by default in Linux 6.5.
FreeSync is an adaptive sync technology for dynamic refresh LCD monitors designed to reduce screen tearing and stuttering caused by out-of-sync content frame rates. Developed by AMD and launched in 2014.
FreeSync is suitable for games with dramatic screen changes, especially those with frequent background switching, such as most FPS, racing games and some RPG games.
As early as 2020, AMD launched a FreeSync compatible video mode for the Linux kernel, initially it required setting the kernel module parameter “amdgpu.experimental_freesync_video=1” to activate.
Then try to enable the FreeSync function by default in Linux 5.18.
But it turns out that the Linux FreeSync driver at that time was not perfect enough.
This function received a large number of reports of crashes and failures from community users, and finally canceled the default enabled state.
But this week AMD engineers sent out the latest Linux driver patch , which overhauls the FreeSync feature, fixes previously reported hangs and corruption on eDP panels, and improves code robustness in corner cases sex.
Judging by emails from AMD engineers, this FreeSync is considered safe in the latest tests and can be enabled out of the box.
This week’s AMDGPU DC patch also brings performance improvements, power-saving optimizations, screen flickering on high-resolution monitors, and other bug fixes to eliminate possible hangs or crashes in different situations.
If the review is passed, this series of patches is expected to enter the mainline of the Linux 6.5 kernel, and then the FreeSync function will be enabled by default in the kernel again.
