[PATCH] tpm: Skip loopback image measurement

it. This method is important to avoid running out of memory, since loopback images can be very large. Trying to read and measure the whole image at once could cause out of memory errors and disrupt the boot process. Signed-Off-by: Michael Chang --- grub-core/commands/tpm.c | 10 ++ 1

[PATCH] Fix screen coud be filled with leftover artifacts

utput. The issue is fixed by ensuring grub_console_cls() to work through lazy mode-setting, while also avoiding screen clearing for the hidden menu, which the flicker-free patch aims to improve. Fixes: 2d7c3abd8 (efi/console: Do not set text-mode until we actually need it) Signed-off-by: Michael

[PATCH] lvm: allocate metadata buffer from raw contents

allocate just what’s needed for the raw metadata. This change effectively reduces the buffer size while still working correctly. In my test system on openSUSE, the buffer size for LVM metadata dropped from 2,088,960 bytes to 1,119 bytes, which is a big improvement. Signed-off-by: Michael Chang
