User visible: - Beautifiers for the 'cmd' arg of several ioctl types, including: sound, DRM, KVM, vhost virtio and perf_events. This was done by using scripts that extract the information from the UAPI headers, generating string tables that are then used in the 'perf trace' syscall argument ioctl beautifier. More work needed to further use it, for instance, to use the _IOC_DIR value where it is used sanely to suppress the third argument, to set formatters for non-pointer values and ultimately for using eBPF + pahole-like code to collect + beautify structs in the third arg. Using the current scheme of having tools/ copies of kernel headers we'll make sure tooling stays working when changes are made to the kernel ABI headers and will be notified when they get changed, reducing the time for 'perf trace' to support new ABIs and allowing the tools/perf/ codebase to have the definitions it needs to build in dozens of distros/versions, as routinely tested using containers for, at this time, 47 environments.
