Subject: [PATCH V6 13/15] KVM: MIPS: Add more MMIO load/store instructions emulation
Date: Sun, 17 May 2020 12:06:10 +0800	[thread overview]
Message-ID: <1589688372-3098-14-git-send-email-chenhc@lemote.com> (raw)
In-Reply-To: <1589688372-3098-1-git-send-email-chenhc@lemote.com>

This patch add more MMIO load/store instructions emulation, which can
be observed in QXL and some other device drivers:

1, LWL, LWR, LDW, LDR, SWL, SWR, SDL and SDR for all MIPS;
2, GSLBX, GSLHX, GSLWX, GSLDX, GSSBX, GSSHX, GSSWX and GSSDX for
   Loongson-3.
