following the recipe from recent commits in #623 where I did the same for 6.5.11 with good results for the 0 tps issue. Let's see whether we can solve 0 tps issue on the 5.15.80 kernel by using this config. Recipe: (In the docker container set up via the instructions I added in #622 ) ``` extract kernel config from the linux-modules deb in ubuntu: https://kernel.ubuntu.com/mainline open `make menuconfig` and save, without any changes default hostname + =y instead of =m for isofs sed -i 's/=m/=n/g' ./neonvm/hack/linux-config-6.5.11; then make menuconfig uncheck "Automatically sign all modules" uncheck 'Enable different security model' (SECURITY=n) this avoids module signing stuff and other complexity we don't care about inside neonvm, like selinux set empty string for 'Additional X.509 keys for default system keyring' set empty string for 'X.509 certificates to be preloaded into the system blacklist keyring' ```

kernel build & push to docker under same 5.15.80 tag: https://github.com/neondatabase/autoscaling/actions/runs/6903092257 |

just small notice: now |

Yeah, I think this was just used for testing and not intended to be merged, but cc @problame to cofirm |

The idea was to merge & ship this if it fixes the 0-tps issue on 5.15.80 (less risk of introducing other regressions). A few MiBs of kernel don't matter right now (neither as storage nor DRAM footprint). |
