Subject: [PATCH] video: limit the resolution for fixed bimap font
|
|
|
|
As grub uses fixed bitmap font and also its size is a fixed property, it is not
|
|
possible to accommodate to all resolutions, therefore we raise some limit to
|
|
the preferred resolution as most themes are designed on popular device and the
|
|
resolution in its prime, which is supposedly Full HD.
|
|
|
|
This change also makes grub font readable on hiDPI device without going through
|
|
the steps in.

v2: efi_gop: Avoid high resolution when trying to keep current mode.
