Ed Maste <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #59 from Ed Maste <[email protected]> --- ACPI FADT VGA check was added in: commit c2272faa06dec2f027c5359529cf8f4f3593c164 Author: Roger Pau Monné <[email protected]> Date: Tue Mar 13 09:38:53 2018 +0000 vt_vga: check if VGA is available from ACPI FADT table On x86 the IA-PC Boot Flags in the FADT can signal whether VGA is available or not. In Linux presence of the the flag sets x86_platform.legacy.no_vga = 1 which is used in only one place, arch/x86/xen/enlighten_hvm.c xen_hvm_guest_late_init() In particular as far as I can tell it does not appear to control whether the VGA console is probed or not. It seems there is a lot of firmware with broken ACPI tables that incorrectly sets this flag and it may be better to ignore it. Roger, is it possible that the flag could be used only w/ Xen? -- You are receiving this mail because: You are the assignee for the bug.
