Some modules are involved in the display output without to rely on
drm_crtc_init.
This is the case for the meson_dw_hdmi. This module need to be included
into the initramfs in both hostonly and generic modes.

On arm, many drm drivers are located in the plaform bus.
Adding the platform bus will allow drm drivers to be included in the
initramfs when using hostonly mode.

If i contains a space, there is a need to protect the variable usage in some cases.
This will occurs when a next patch will enable platform bus with such case:
'/sys/bus/platform/devices/Fixed MDIO bus.0'

DRM drivers are filtered for drm_crtc_init symbol,
but not all drivers use it. Especially, cirrus driver
doesn't use it since Linux 5.2.
The practical result is text plymouth theme instead of graphical when in qemu.
Fix it by looking also for drm_dev_register symbol.

For the shell scripts, new environment variables were introduced.
dracutsysrootdir is the root directory, file existence checks use it.
DRACUT_LDCONFIG can override ldconfig with a different one that works
on the sysroot with foreign binaries.
DRACUT_LDD can override ldd with a different one that works
with foreign binaries.
DRACUT_TESTBIN can override /bin/sh. A cross-compiled sysroot
may use symlinks that are valid only when running on the target
so a real file must be provided that exist in the sysroot.
DRACUT_INSTALL now supports debugging dracut-install in itself
when run by dracut but without debugging the dracut scripts.
E.g. DRACUT_INSTALL="valgrind dracut-install or
DRACUT_INSTALL="dracut-install --debug".
DRACUT_COMPRESS_BZIP2, DRACUT_COMPRESS_LBZIP2, DRACUT_COMPRESS_LZMA,
DRACUT_COMPRESS_XZ, DRACUT_COMPRESS_GZIP, DRACUT_COMPRESS_PIGZ,
DRACUT_COMPRESS_LZOP, DRACUT_COMPRESS_ZSTD, DRACUT_COMPRESS_LZ4,
DRACUT_COMPRESS_CAT: All of the compression utilities may be
overridden, to support the native binaries in non-standard places.
DRACUT_ARCH overrides "uname -m".
SYSTEMD_VERSION overrides "systemd --version".
The dracut-install utility was overhauled to support sysroot via
a new option -r and fixes for clang-analyze. It supports
cross-compiler-ldd from
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
DRACUT_INSTALL_PATH was introduced so dracut-install can work with
a different PATH. In a cross-compiled environment (e.g. Yocto), PATH
points to natively built binaries that are not in the host's /bin,
/usr/bin, etc. dracut-install still needs plain /bin and /usr/bin
that are relative to the cross-compiled sysroot.
The hashmap pool allocate_tile/deallocate_tile code was removed
because clang-analyze showed errors in it. hashmap_copy was removed
because it wasn't used and clang-analyze showed errors in it.
DRACUT_INSTALL_LOG_TARGET and DRACUT_INSTALL_LOG_LEVEL were
introduced so dracut-install can use different settings from
DRACUT_LOG_TARGET and DRACUT_LOG_LEVEL.

The code in 50drm which tries to include all DRM drivers for
hardware attached to the system did not look for virtio devices.
So if the system is a VM using the 'virtio' graphics adapter,
the 'virtio-gpu' module which should be included is not. This
extends the code to also look for virtio devices.

The recently upstreamed virtualbox video driver (vboxvideo) is shipped
in the staging directory. We need to probe it before Xorg is loaded to
avoid a corrupted X.
In general it is a good practice to look also in the staging directory
for DRM drivers.

At least on x86 on Bay and Cherry Trail devices the pmw-lpss modules must
be in the initrd too, otherwise the i915 driver will still load, but
it will report the following error:
[drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip
And not register /sys/class/backlight/intel_backlight and users will
not be able to control their backlight.

AMD's HSA Linux kernel driver (amdkfd) has been merged into the mainline
kernel since kernel 3.19.
However, for the driver to work, it needs to be included in the default
initramfs image, together with the amd_iommu_v2 driver.
The radeon driver (AMD's kernel graphic driver) calls amdkfd during its
initialization and probing stages. Because radeon is included in the
initramfs image, it tries to initialize amdkfd during the early boot
stages. However, as amdkfd is not present there, it fails.
That doesn't harm radeon operation. However, it disables the HSA
abilities in the machine.
Because of the current design, if you later try to "modprobe amdkfd",
you won't be able to run HSA applications, even though the driver will
be loaded.

Kdump module will need the drm and kms kernel modules so user can see the
emergency shell at least.
Fix this by split 50plymouth module to 50drm and 50plymouth. Moving the
installkernel part to 50drm so user can use drm directly without adding
extra plymouth utils.

The latest plymouth no longer relies on dracut to provide functions
needed to install binaries/libs so the check for a variable name
no longer works and the old, built-in script is used instead thus
breaking the new drm and framebuffer plymouth module installation.
This rewrites a portion of the module to support xz, as well as allow
an easier expansion should future compression methods for kernel
modules ever materialize.
Like -H, we need to poll every module to check if it is needed
to mount a specific device in '--mount'.

This should fix initial initrd generation during install.
If the modules are not desired to be used, the nokmsboot kernel
command line should disable them.
