Can you try to allocate proper amounts of CMA memory with the cma= kernel command line parameter?
In /boot/grub2/grub.cfg I see:
linux /boot/Image-4.13.2-1-default root=UUID=d578a86e-c033-4290-8f9f- e9ddd2489659 root=/dev/disk/by-id/mmc-SD16G_ 0xda58f009-part2 disk=/dev/disk/by-id/mmc-SD16G_0xda58f009 resume=/dev/disk/ by-id/mmc-SD16G_0xda58f009-part3 quiet splash=silent ply mouth.enable=0 swiotlb=512,force cma=384M console=tty0 console=ttyS0,115200n8 quiet
Should swiotbl=512 be larger? cma=384M seems large enough.
Yeah, give that a try. swiotlb sizing is odd - it‘s in some multiple that I can never remember. 1k or so?

I found swiotbl=512 means 512 slabs of 128K memory, so this takes 64M, which is mentioned as the default value. I will try 768.
Did not help. Also changed cma=384M in cma=512M, did not help either. -- fr.gr. Freek de Kruijf member openSUSE -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
