[seL4] speed up sel4

When running sel4 in my processor it is taking too long to get this line "vka_alloc_object_at_maybe_dev@object.h:65 Failed to allocate object of size 268435456, error 1" Is there any options to reduce allocation object size? Or any other methods to speed up Regards, Sreenadh S CDAC, Trivandrum, India
