 OK, this shot is just an update about what's going on with the BPF program pack. So the big picture is like, we have a lot of BPF program. They're small. We load that long load them all the time. So we want to make a way to have them share a huge page so we don't have to exercise the page allocation. And there's a big reason behind that if we have Vmalloc some page, and we set the memory to be not a regular read-write, because we just set it to be executable. It's caused the fragmentation of the direct map. And over time, it will make the system slower and slower. And also, if we have shared a huge page, we'll get less pressure in the instruction TLB. So where we are? We're at V1. So we call it the BPF program pack. It's a bean pack algorithm just for BPF program. Basically, we reserve the 2 megabyte region and use that for small BPF programs. It has a very naive allocator, but it works. And it's in upstream since 518 kernel for x86. And there is a patch coming for PowerPC, but I think it's not ready. But it's close. It's close to be shipped, I think. And so this is what happened in the second half of last year. I want to make it more generic. We call it it's curable memory allocator. And we re-use the V map allocator. It's the Vmalloc, whatever behind Vmalloc. And we make it can be used with BPF program, BPF trampoline, and can be used for module tags, only the tags. And F2 is K-Prop. Basically, you want a small chunk of the tags. You can use a chunk of this 2 megabyte page instead of the whole data page of your own and fragment the directory map. Well, this work made the 2LWM, but didn't make through reviews. But that turned into V3. It's a new module allocator. And the goal is to get a huge page for module tags and data, BPF program, and everything else on the list. But we need to change them one at a time. But this will be the foundation for all of them. We can share the page among all this, as long as you have the same permission. Read only, go read only, executable, go executable, and read write, share the page with other read write stuff. So where are we? We have the major, I think, to me, that's the biggest, the highest part is to change the module code to be ready to get a new allocator. This part finally landed to 6.4 RC1 yesterday, pretty much. And the second part is we have, right now, with the module allocator, basically, pretty much every architecture have their own variation of the module alloc. And Thomas has suggested a way to unify all those. So we don't have, in the future, change each of them one at a time, which is great. But that's working progress. And the third part would be reuse the Vmalloc area allocator from Vmalloc, which is similar to V2. I was hoping that it won't take too much time. And the part for BPF, we have BPF trampoline, BPF program to use module alloc instead of BPF program pack. And we will just remove BPF program pack after that. And that's where we are. So any questions? I'm hoping to submit a patch before the next merge window. But we may end up baking it for some time. Maybe we cannot make a 6.5 merge window. But I do plan to finish the majority of it before the next merge window. Maybe I'm wrong. Does this kind of tie into the global syskittle that controls how much memory we end up using for BPF programs? It's not related at all. OK, thank you very much. I'm super happy that this makes progress. Thank you. I know it's getting slower than I expected.
