xen cache colors in ARM

[Oleg Nikitenko <oleshiiwood@xxxxxxxxx>]

Hello,

I tried to turn on this scheme and ran into panic.

Where was I wrong ?

Xen command line

xen,xen-bootargs = "console=dtuart dtuart=serial0 dom0_mem=1600M dom0_max_vcpus=2 dom0_vcpus_pin bootscrub=0 vwfi=native sched=null timer_slop=0 way_szize=65536 xen_colors=0-3 dom0_colors=4-7";

Xen config color build settings

CONFIG_COLORING=y

Xen log:
