Subject: [PATCH v2 0/4] linux-user: Emulate /proc/cpuinfo on s390x
Date: Mon, 5 Jun 2023 13:39:46 +0200 [thread overview]
Message-ID: <20230605113950.1169228-1-iii@linux.ibm.com> (raw)
v1: https://lists.gnu.org/archive/html/qemu-devel/2023-06/msg00299.html
v1 -> v2: Add output examples (David).
Simplify the CPU 0 special case (David).
Fix building on s390x hosts.
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
