Source: linux Severity: wishlist A few requests for changes to the cloud configuration:
- Please disable CONFIG_ACPI_BGRT; a cloud kernel doesn't need to spend time or code space looking for a boot logo that won't exist. - Please disable the CONFIG_CPU_SUP_* options for CPUs that no cloud provider uses. - Please disable CONFIG_GNSS_*, which won't be hooked up to a cloud server. - Please disable CONFIG_GTP for the same reason. - Please configure CONFIG_INPUT_MOUSEDEV as a module, not built-in, as most cloud servers won't have a mouse and probing for one takes time. - Please consider changing the default kernel compression to GZIP, which decompresses faster and thus boots faster. - Please change CONFIG_NET_MPLS_GSO from y to m (and consider doing this for the non-cloud kernel too); it doesn't need to be built into the kernel. - Please change CONFIG_NF_NAT_* and CONFIG_NF_MASQUERADE_* from y to m, as many systems won't need those modules and shouldn't need to load their code. - Please compile in the NVME driver and the EXT4 filesystem; this will allow many cloud systems to avoid using an initramfs at all, which substantially improves boot time. - Please disable CONFIG_NUMA_EMU, only used to create fake-NUMA systems for debugging. - Please disable CONFIG_PCIPCWATCHDOG, CONFIG_PPS, and CONFIG_RMI4_*, which won't appear on a cloud server. - Please enable CONFIG_SCHED_MC_PRIO (on both cloud and non-cloud kernels). - Please disable CONFIG_VFIO_PCI_VGA and CONFIG_VGA_SWITCHEROO, which won't appear on cloud.
