From: Salva Peiró Date: Mon, 27 Jul 2015 08:51:52 +0000 (+0200) Subject: megasas: Add write function to handle write access to PCI BAR 3 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=55875fc4ca45a35e36134663ade946d86fe7bfcd;p=qmiga%2Fqemu.git megasas: Add write function to handle write access to PCI BAR 3 This patch fixes a QEMU SEGFAULT when a write operation is performed on the memory region of the PCI BAR 3 (base address space). When a writeb(0xe0000000) is performed the .write function is invoked to handle the write access, however, since the .write is not initialised, the call to 0, causes QEMU to SEGFAULT.
