Subject: [vfio-users] Asus P6T Deluxe unofficial BIOS
Message-ID:

Hey there,
i've got two Boards, Asus P6T Deluxe and non-Deluxe Version. Ive running a
Xeon X5650 on it, but
VT-d is routed through bios(dmesg told me), and the DMAR-Table is broken.
On the xen page i've found this "ASUS P6T Deluxe (Intel X58 chipset)
requires (currently non-public) BIOS update to correct DMAR-table issue".
Does anyone know if there is a unofficial bios with corrected DMAR-Table?
google is not my friend^^
didnt find anything useful :(
greet Spirit
I have the same motherboard and also sought that bios, without success.
There is however someone else who may have tried it

See Alex's response suggesting use of
|memmap=nn[KMG]$ss[KMG] [KNL,ACPI] Mark specific memory as reserved.
Region of memory to be reserved is from ss to ss+nn. Example: Exclude
memory from 0x18690000-0x1869ffff memmap=64K$0x18690000 or
memmap=0x10000$0x18690000|
I haven't tried this myself so would be interested in your feedback :)
