Subject: [Qemu-devel] [PATCH] PowerPC: Add TM bits into msr_mask
Date: Wed, 28 Feb 2018 09:51:37 +0800	[thread overview]
Message-ID: <1519782697-13100-1-git-send-email-wei.guo.simon@gmail.com> (raw)

From: Simon Guo <wei.guo.simon@gmail.com>

During migration, cpu_post_load() will use msr_mask to determine which
PPC MSR bits will be sync to the target side. Hardware Transaction
Memory(HTM) has been supported since Power8. This patch adds TM/TS bits
into msr_mask for Power8, so that transactional application can be
migrated across qemu.
