Do you know if the firmware allows the kernel to be entered in EL2 (which is the arm64 name for HYP)? So can we run kvm? If you have a booted kernel, can you grep for "EL2" and "kvm" in the dm= esg? Also you should merge this patch into 3/8, same for 8/8. > Signed-off-by: Andreas F=C3=A4rber > --- > arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi | 4 +++- > 1 file changed, 3 insertions(+), 1 deletion(-) >=20 > diff --git a/arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi b/arch/arm64= /boot/dts/amlogic/meson-gxbb.dtsi > index 0ae089bd1806..5088ae3ff653 100644 > --- a/arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi > +++ b/arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi > @@ -117,7 +117,9 @@ > gic: interrupt-controller@c4301000 { > compatible =3D "arm,cortex-a15-gic", "arm,cortex-a9-gic"; I think "arm,gic-400" is the name to use here these days, especially fo= r arm64. > reg =3D <0x0 0xc4301000 0 0x1000>, > - <0x0 0xc4302000 0 0x0100>; > + <0x0 0xc4302000 0 0x0100>, Please use 0x2000 for the size here. I guess this is really the GIC-400 from ARM, and in this case this is the right size, [1] is the reference here. This will enable EOI mode 1 for KVM. Cheers, Andre.
