How do i find the linux kernel version from which a certain feature was first incorporated. For example , How do i find the first kernel version which had support for GRO (generic receive offload) ?

Thanks, Amit

Hi Amit,

Kernel version is 2.6.29 refer http://lwn.net/Articles/358910/

Regards, Rohan Puri

Thanks Rohan, But still there should be some information in a changelog for each kernel release somewhere. Currently looking for such information in Linus's tree(https://github.com/torvalds/linux/tree/), but it seems like getting such kind of information is quite engaging. - Amit

You can always use a LXR to find when a feature was first incorporated. Here is a link to just one of the several LXR available: http://lxr.free-electrons.com/

You mean to say browse the code, no changelog or something ? -Amit

Well I was not thinking of browsing the code, because that would take a long time.  But I was thinking of an identifier search which is much faster and you can cover several kernel versions in a lot less time than it would take to read a changelog of every release looking for a feature.

I have recently had to track down several additions and changes to the kernel that broke my drivers. Short of randomly googling to find the answer Jeff is right, using one of the LXR sites seems to be just about the only way to figure out where the change happened while also keeping your sanity. If there is a better way I would love to know. Matt Schulte
