Change Details

Implement vt_vbefb to support VBE framebuffer with VT. vt_vbefb is built based on vt_efifb and is assuming similar data for initialization. Therefore we can use the struct efi_fb, but with added field fb_bpp for depth (UEFI is only supporting 32-bit depth and was not needing it) and we use MODINFOMD_VBE_FB to identify the structure in kernel metadata.

Implement vt_vbefb to support Vesa Bios Extensions (VBE) framebuffer with VT. vt_vbefb is built based on vt_efifb and is assuming similar data for initialization. Therefore we can use the struct efi_fb, but with added field fb_bpp for depth (UEFI is only supporting 32-bit depth and was not needing it) and we use MODINFOMD_VBE_FB to identify the structure in kernel metadata. struct efi_fb, is populated by boot loader, and is passed to kernel via metadata payload.
