Hello all, I would like to announce the first successful emulation of Cavium Networks' Octeon hardware (http://www.caviumnetworks.com/OCTEON_MIPS64.html). I'm using heavy modified QEMU 0.12.2 and MontaVista's CGE 5.1 (http://www.mvista.com/product_detail_cge.php) as the target Linux system. Bu

[Qemu-devel] How to get 64-bit MMIO?

2010-02-18 Thread Dmitry Antipov
Hello all, is there any support for 64-bit MMIO? I'm trying to emulate 16750-like UART by adopting current 16550A emulation. The problem is that my (MIPS) hardware is 64-bit, and native software issues 64-bit load/stores (LD/SD) to talk with all hardware registers, which are all 64-bit too (for
