Subject: [PATCH v1 0/4] Missing endianness conversions in user mode
Date: Fri, 17 Feb 2023 17:35:23 +0100 [thread overview]
Message-ID: <20230217163527.619486-1-Mathis.Marion@silabs.com> (raw)
From: Mathis Marion <mathis.marion@silabs.com>
For a bit of context, I was trying to test a network border router [1]
daemon using the MIPS architecture (see [2]). I didn't have access to
real MIPS hardware so I figured I would emulate it using QEMU user mode.
I ran into a couple of problems all related to endianness conversion for
syscalls between host and target as MIPS is big endian and my x86 host
is little.
