What is "union aliasing"? And
Just like with PCI options ROMs, which we save in the setup_efi_pci*
functions from arch/x86/boot/compressed/eboot.c, the EFI code / ROM itself
sometimes may contain data which is useful/necessary for peripheral drivers
to have access to.
Specifically the EFI code may contain an embedded copy of
Sometimes it is useful to be able to dump the efi boot-services code and
data. This commit adds these as debugfs-blobs to /sys/kernel/debug/efi,
but only if efi=debug is passed on the kernel-commandline as this requires
not freeing those memory-regions, which costs 20+ MB of RAM.

Some of the tablets with such a touchscreen have a touchscreen driver, and

Not only silead touchscreens need some extra info not available in the

Hi All,
Here is v4 of my patch-set to add support for EFI embedded fw to the kernel.
Changes since v3:
-Drop note in docs about EFI_FIRMWARE_VOLUME_PROTOCOL, it is not part of
UEFI proper, so the EFI maintainers don't want us referring people to it
-Use new EFI_BOOT_SERVICES flag
-Put the new
The commit
318a19718261 ("device property: refactor built-in properties support")
went way too far and brought a union aliasing. Partially revert it here
to get rid of union aliasing.
Note, Apple properties support is still utilizing this trick.
