Enable for SND_SOC_INTEL_SOUNDWIRE_SOF_MACH kernel module. This is used
on some 10/11th gen Intel laptops such as the XPS 17 97[00|10]
Enable SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES as well - this is required dep
Enable Intel Software Guard eXtensions (SGX) on x86 when using Linux
5.11.0 or later. Also enable KVM guests to create SGX enclaves if
running Linux 5.13.0 or later.
> The MediaTek protocol support enables firmware download support and chip initialization for MediaTek Bluetooth USB controllers.
Necessary to make Bluetooth work on some MediaTek controllers.
Core scheduling is a recent innovation in newer kernels to help run
certain untrusted compute workloads more safely in the face of
vulnerabilities like Spectre. In short: it lets processes assign a
unique "cookie" to some group of processes to indicate they are allowed
to be scheduled together on the same SMT-capable core. This helps
mitigate attacks that rely on observing usage of CPU execution units by
cohabitated threads.
Some extra details are available via Linux Weekly News:

After linux 5.14.11 FB_SIMPLE conflicts with DRM_SIMPLEDRM, which
will fail configuration, when DRM_SIMPLEDRM is configured as a module
and FB_SIMPLE gets requested as builtin.
Do not enable DRM_SIMPLEDRM as a temporary workaround, until good
enough migration path is found.
Initrd loader is not enabled by default in some aarch64 kernels,
which makes systemd-boot booted kernels fail by default, add this
everywhere, since this is a sane default even when it's already in
some kernel defaults.
BTF is a new, lightweight debug information format tailored specifically
for the needs of eBPF, allowing eBPF programs to be portable across
various kernel versions, configurations and distributions. This is used
by bpftrace and lots of new eBPF-based tooling to avoid a dependency
on LLVM on the host.
BTF debug information is enabled on all major distributions: Fedora 31+,
RHEL 8.2+, Ubuntu 20.10, Debian 11 and ArchLinux all have enabled it.
Enabling BTF debug information requires adding two new dependencies to
the kernel build: Python3 and pahole. Those will be used to generate the
BTF debugging information.
They were enabled in 5.4 but then removed. Let's enable them explicitly
here. To keep the version constraints simple, we match kernel >5.4 even
though some of them are available since 4.x.
LPAE was enabled to support native armv7l builders running in QEMU on aarch64,
but this option disables support for processors which don't support LPAE, which
are still relatively common. In particular, Beaglebones use the Cortex-A8, which
doesn't support LPAE.
Also, if you attempt to boot an LPAE kernel on a CPU that doesn't support it,
it fails before even earlycon is initialized. This makes the problem difficult
to debug without enabling CONFIG_DEBUG_LL or using a hardware debugger.
Turns VMware guest mouse support on in the kernel. This is needed for running Wayland and non-root X in a VMWare guest. In a pre-Wayland world the `xf86-input-vmmouse` userspace driver would have handled this for us. This allows the mouse to properly work in a vmware guest (for example it can now leave the vmware window).
