Dear Jan Thanks for your guidance I have another question, in the " Setup on Banana Pi ARM board", it mentioned that " The kernel requires a small patch in order to build the Jailhouse driver module", the file of " arch/arm/kernel/armksyms.c " need to modified.
My understanding for this is as following: 1 git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git 2 cd ~/linux-stable 3 git checkout v4.3.3 4 Modify the " arch/arm/kernel/armksyms.c " manually by VIM. 5 for i in ../bananian/kernel/4.3.3/patches/*; do patch -p1 < $i; done 6 ....... Is my understanding right? -----Original Message----- From: Jan Kiszka [mailto:[email protected]] Sent: Tuesday, June 4, 2019 2:03 PM To: Xiong, Lei (CT RDA FOA ART-CN1) Cc: [email protected] Subject: Re: How to disable CONFIG_VIDEO in the U-Boot config On 04.06.19 07:47, Xiong, Lei (CT RDA FOA ART-CN1) wrote: > Dear Jan > > In fact, my hardware platform is banana PI M1+, I do not find "Banana Pi M1+" > in the " images.list ". > Is there a jailhouse-images supported for "Banana Pi M1+"? > Not explicitly. We support the classic Orange Pi Zero, but that is also A20-based. Maybe you can use that image on the M1+ as well, only tuning some boot parameters and using different Jailhouse configs (all available ones are being installed) in the end. I don't have such board in reach to cross-check, unfortunately. In general, ARMv7-based setups with Jailhouse need to be considered more as demonstrations than as production platforms. Those SOCs typically lack SMMUs that you need for full isolation, and most activities on ARM-side now go into v8 designs.
