Subject: [Qemu-devel] [PULL 2/5] target/openrisc: Make coreid and numcores variable
Date: Fri, 13 Oct 2017 23:57:11 +0900 [thread overview]
Message-ID: <20171013145714.2740-3-shorne@gmail.com> (raw)
In-Reply-To: <20171013145714.2740-1-shorne@gmail.com>
Previously coreid and numcores were hard coded as 0 and 1 respectively
as OpenRISC QEMU did not have multicore support.
Multicore support is now being added so these registers need to have
configured values.
