Detailed explaination about the patches for Ubuntu.

[sunlong169]

As per this issue, which says that[emphasis mine]:

With all kernels v.416+ you get the standard HW timestamp for free (w/o kernel patches), You'd still need to apply the patches if you need the extended frame metadata - exposure, gain, laser poser, etc. But if you're only interested in getting HW timestamps then using unmodified kernel should suffice.

Could somebody give some detailed explanation about the pitches for Ubuntu?

What modules do the aforementioned pitches have modified? Could somebody give a detailed explanation of how these modules are modified?

Hi @sunlong169 Notes about the changes made by the patching process can be found within the patch script patch-realsense-ubuntu-lts.sh at the link below. The script makes changes to the uvcvideo and videobuf2 modules.
