For kata containers, rootfs is used in the read-only way.
EROFS can noticably decrease metadata overhead.
On the basis of supporting the EROFS file system, it supports using the config parameter to switch the file system used by rootfs.

In order to let upcall being used by Kata Container, we need to add
those patches into kernel build script.
Currently, only when experimental (-e) and hypervisor type dragonball
(-t dragonball) are both enabled, that the upcall patches will be
applied to build a 5.10 guest kernel.
example commands: sh ./build-kernel.sh -e -t dragonball -d setup

CONFIG_X86_SGX is introduced after kernel 5.11, and that config is a
default x86_64 config for Kata build-kernel.sh script.
But if we use -v to specify any kernel version below 5.11 will cause an
inevitable error because CONFIG_X86_SGX is not supported in older
kernels and that may cause problem for the situation if we need kernel
version below 5.11.
So I propose to put CONFIG_X86_SGX into whitelist.conf to avoid break
building guest kernel below 5.11.

The latest kernel with TDX support should be pulled from a different

Provide the `/proc/config.gz` file in guest kernels that allow the guest
to determine the kernel configuration used to build the running kernel.
Note that since `gunzip` expects to rename the gzip'ed file it operates
on, to use this feature you need to run something like the following in
the container environment:
```bash
# cat /proc/config.gz|gunzip -c
```

Pull #2795 recently added support for a closer-to-OCI behaviour for
VFIO devices, in which they appear to the container as VFIO devices,
rather than being interpreted by the guest kernel. However, in order
to use this, the Kata guest kernel needs to include the VFIO PCI
driver, along with dependencies like the Intel IOMMU driver.
The kernel as built by the scripts within Kata don't currently include
those, so this patch adds them.
fixes#2913
Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
The guest kernel configuration suggested for Kata, and which is used by the
CI didn't include CONFIG_PCI_MMCONFIG. That's kind of weird, MMCONFIG is
the modern normal way of handling configuration cycles.
In addition, due to a complex set of interactions through the ACPI code,
disabling MMCONFIG means that SHPC hotplug doesn't work: the driver is
included in the guest kernel, but will fail to probe on PCI to PCI bridges,
meaning it won't actually be activated.
Enable MMCONFIG so that we suggest and testa more typical guest kernel
configuration.
