[PATCH 0/4] linux-user: Emulate /proc/cpuinfo on s390x

Posted by Ilya Leoshkevich 10 months, 3 weeks ago

Hi,

This series introduces /proc/cpuinfo linux-user emulation for s390x.
/proc/cpuinfo emulation already exists for sparc, hppa and riscv; this
series follows the pattern established for these platforms.

Patch 1 is a fix for an issue that I noticed while looking for ways to
get to the "identification" field.

Patches 2 and 3 introduce the necessary helpers.

Patch 4 is the actual implementation.

The trigger for this work is a bug report filed by Tulio [1], which has
to do with the llvm-project testcases failing under qemu-user.

Best regards,
Ilya
