Subject: [PATCH] Stop grub.efi from always printing "dynamic_load_symbols
|
|
%p\n" during boot
|
|
|
|
Commit 972aa68d2bf5 ("Make a "gdb" dprintf that tells us load addresses.")
|
|
added some debug prints to help with running gdb against grub.
|
|
|
|
Besides adding a new grub_dl_print_gdb_info () function which uses
|
|
`grub_qdprintf ("gdb", ...);` it also adds a new grub_efi_print_gdb_info ()
|
|
call to grub_efi_init ().
|
|
|
|
grub_efi_print_gdb_info () is intended for the gdbinfo command and uses
|
|
a non debug grub_printf () call leading to grub now always printing this
|
|
message during boot breaking flicker-free boot.
|
|
|
|
Add a new "debug" parameter to grub_efi_print_gdb_info () and use
|
|
`grub_qdprintf ("gdb", ...);` when this is set to silence the printing
|
|
done from grub_efi_init () when debugging is not enabled.
|
|
|
|
Fixes: 972aa68d2bf5 ("Make a "gdb" dprintf that tells us load addresses.")
