Subject: [Qemu-devel] [PATCH v7 42/42] target/sparc: sun4u Invert Endian TTE bit
Date: Fri, 16 Aug 2019 07:39:56 +0000 [thread overview]
Message-ID: <1565941195999.79315@bt.com> (raw)
In-Reply-To: <43bc5e07ac614d0e8e740bf6007ff77b@tpw09926dag18e.domain1.systemhost.net>
This bit configures endianness of PCI MMIO devices. It is used by
Solaris and OpenBSD sunhme drivers.
Tested working on OpenBSD.
Unfortunately Solaris 10 had a unrelated keyboard issue blocking
testing... another inch towards Solaris 10 on SPARC64 =)
