thanks Peter, yes I tried to run an x86 strace under QEMU.
I'll stop this experiment since you are right this won't work for
utilities with device-level I/O and memory operations, I will raise this
requirement to Intel support website firstly.
Best Regards, Yi

Title:
qemu-x86_64 on aarch64 reports "Synchronous External Abort"
Status in QEMU:
New
Bug description:
Purpose: to run x86_64 utilities on aarch64 platform (Intel/Dell network
adapters' firmware upgrade tools)
System: aarch64 server platform, with ubuntu 16.04 (xenial) Linux
4.13.0-45-generic #50~16.04.1-Ubuntu SMP Wed May 30 11:14:25 UTC 2018 aarch64
aarch64 aarch64 GNU/Linux
Reproduce:
1) build linux-user qemu-x86_64 static from source (tried both version 2.12.0
& 2.11.2)
./configure --target-list=x86_64-linux-user --disable-system --static
--enable-linux-user
2) install the interpreter into binfmt_misc filesystem
$ cat /proc/sys/fs/binfmt_misc/qemu-x86_64
enabled
interpreter /usr/local/bin/qemu-x86_64
flags:
offset 0
magic 7f454c4602010100000000000000000002003e00
mask fffffffffffefefcfffffffffffffffffeffffff
3) packaging Intel/Dell upgrade utilities into docker images, I've published
two on docker hub:
REPOSITORY TAG
heyi/dellupdate latest
heyi/nvmupdate64e latest
4) run the docker container on aarch64 server platform:
docker run -it --privileged --network host --volume
/usr/local/bin/qemu-x86_64:/usr/local/bin/qemu-x86_64 heyi/dellupdate:latest
5) finally, within docker container run the upgrade tool:
# ./Network_Firmware_T6VN9_LN_18.5.17_A00.BIN
Errors: in dmesg it reports excessive 'Synchronous External Abort':
kernel: [242850.159893] Synchronous External Abort: synchronous external
abort (0x92000610) at 0x0000000000429958
kernel: [242850.169199] Unhandled fault: synchronous external abort
(0x92000610) at 0x0000000000429958
thanks and best regards, Yi
