Hey Alan, The official repository I think is https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/. What I would do is apply your patch on top of that, and then to update it, rebase the patch onto the new upstream commit you want to update to. This leads to your patches always being at the tip of the commit history and not somewhere buried between commits from upstream. However, this rewrites git history so you'd have to force push the branch to whatever remote you're tracking it in, so keep that in mind. You could do this though and additionally have another branch where you track the patch files themselves that are rebased onto a certain kernel commit (you can export them with "git format-patch upstream/master" if upstream/master is whatever branch the patch is currently rebased on). That of course you don't have to then force push. I hope this helps :P -Marco signature.asc Description: This is a digitally signed message part.

[gentoo-user] Advice sought on the use of a VCS (specifically git) to keep track of my Softscroll patch.
Hello, Gentoo. Over the last few months I've posted several versions of my kernel patch which re-enables soft scrollback. I thought at the time I could just keep a few files informally in my home directory. But I'm already getting confused about what is where, what applies to which kernel versions and so on. Clearly I need to put the patch into a version control system. I would appreciate some advice on this. I think I need to get a clone of the kernel's git repository, and maintain the patch in it as a branch or several branches. Or would it be feasible just to maintain the patch in a VCS? My feeling is that I really need the full repository. Where would I find a suitable kernel git repository to clone? An "official" repository, whatever that means? Ideally, I want one with just the various kernel releases, not one containing gigabytes of intermediate versions. Where would I even start searching to find this out? Once I've got this far, I'll need to think about a versioning scheme for the patch - there are irritating little differences in the console code between versions of the kernel, as recently pointed out by Jorge Almeida, so there would be irritating differences between versions of the patch. Maybe I could put it onto the Gentoo wiki, but that's not in the near future. Thanks for the help! -- Alan Mackenzie (Nuremberg, Germany).

Out of interest, have you tried booting a NUMA enabled kernel to see what dmesg reports? On an old laptop, which definitely has only a single AMD APU, I get: $ dmesg | grep -i NUMA -A2 [0.002078] No NUMA configuration found [0.002080] Faking a node at [mem 0x-0x00042eff] [0.002085] NODE_DATA(0) allocated [mem 0x42effc000-0x42eff] signature.asc Description: This is a digitally signed message part.

I'm currently discovering what version control systems are for. :-( Even though I've only posted two or three versions of my patch, I'm already having difficulty keeping track of it. I no longer believe keeping the patch informally is going to work. I think I'm going to have to clone the git repository of the kernel (about which I'm going to ask on another thread). Anyhow, back to the topic. There's no URL with my patch; it's purely posted on gentoo-users. Maybe I should put it into the Gentoo wiki. But first, I must get it into a proper VCS. As for the two(?) versions of my patch, they differed mainly in the aesthetics - diff.20210405.diff had lots of ugly maintainer comments in it. So, could I ask you please to try that 1-hunk patch I posted yesterday on top of the version you have. Please then tell me whether or not it works.

[gentoo-user] Chrome - no system title bar or boarders
Sorry to cross post. I put this on the KDE list yesterday but no responses. As I run Kubuntu I thought that it would be a better place to start. Starting yesterday morning both of my KDE machines no longer show a system title bar or border for Chrome, and only Chrome. All other apps are fine. Right clicking the Chrome tab area has a checkbox for 'Use system title bar and borders' but it does nothing. Chrome version 94.0.4606.54. Losing the title bar means losing (as far as I know) the ability to pin an instance of Chrome to all virtual desktops which I use for browser streamed media - YouTube, Netflix, etc. I've switched that window to Firefox for the time being. As Gentoo is usually a bit further forward I wondered if anyone here using Chrome and KDE has seen this issue? Thanks, Mark

I've booted a kernel with no NUMA config, and it seems to run fine on this single-socket Ryzen motherboard. I just get the one entry in dmesg: $ dmesg | grep -i numa [0.297998] pci_bus :00: on NUMA node 0 That's it. I'm running five BOINC projects, some of which run on vbox, so on this motherboard it seems clear that I don't need NUMA. -- Regards, Peter.

Re: [gentoo-user] Do I need NUMA set up in my kernel?
You'd need NUMA if you had a NUMA machine. In current context, that would be either a) a dual socket system, b) an amd threadripper, or c) some of the really high core xeons. If your motherboard doesnt have certain memory banks allocated to certain processors or cores, you're probably not running a NUMA machine. NUMA stands for non-uniform memory access, it means that certain processor cores have more direct access to certain parts of memory than others do (e.g. to access the other memory they need the other cpu core to pass it through) On Thu, 23 Sept 2021 at 19:39, Charlotte Delenk wrote: > > Hi Peter, > > On 9/23/21 10:59, Peter Humphrey wrote: > > Hello list, > > > > I see "[0.003162] No NUMA configuration found" in dmesg.
