Subject: Cannot compile UML in Ubuntu 20.04.5 anymore
Date: Fri, 03 Mar 2023 09:34:36 +0100 [thread overview]
Message-ID: <6df2ecef9011d85654a82acd607fdcbc93ad593c.camel@huaweicloud.com> (raw)
Hi
it looks like one recent commit causes the kernel build to break.
GEN scripts/gdb/linux/constants.py
In file included from /usr/include/stdlib.h:1013,
from arch/um/os-Linux/helper.c:6:
/usr/include/x86_64-linux-gnu/bits/stdlib-float.h: In function ‘atof’:
/usr/include/x86_64-linux-gnu/bits/stdlib-float.h:26:1: error: SSE register return with SSE disabled
26 | {
| ^
CC init/noinitramfs.o
It works again by reverting commit 884981867947 ("rust: arch/um:
Disable FP/SIMD instruction to match x86").
$ cat /proc/cpuinfo
[...]
processor : 31
vendor_id : AuthenticAMD
cpu family : 23
model : 49
model name : AMD Ryzen Threadripper PRO 3955WX 16-Cores
Thanks
Roberto
