2011-08-09etrax: Remove hw/etraxfs.c.Edgar E. Iglesias
The Bare ETRAX FS board was a fictive machine that I used when developing the CRIS system emulation. Since we support the real AXIS-dev88 developer boards, there is no reason to keep the fictive one around. This commit also removes the double registration of the axis-dev88 board.

2011-07-29Hierarchical memory region APIAvi Kivity
The memory API separates the attributes of a memory region (its size, how reads or writes are handled, dirty logging, and coalescing) from where it is mapped and whether it is enabled. This allows a device to configure a memory region once, then hand it off to its parent bus to map it according to the bus configuration. Hierarchical registration also allows a device to compose a region out of a number of sub-regions with different properties; for example some may be RAM while others may be MMIO.

2011-07-21Add hard build dependency on glibAnthony Liguori
GLib is an extremely common library that has a portable thread implementation along with tons of other goodies. GLib and GObject have a fantastic amount of infrastructure we can leverage in QEMU including an object oriented programming infrastructure. Short term, it has a very nice thread pool implementation that we could leverage in something like virtio-9p. It also has a test harness implementation that this series will use.

2011-06-20Switch build system to accompanied kernel headersJan Kiszka
This helps reducing our build-time checks for feature support in the available Linux kernel headers. And it helps users that do not have sufficiently recent headers installed on their build machine. Consequently, the patch removes and build-time checks for kvm and vhost in configure, the --kerneldir switch, and KVM_CFLAGS. Kernel headers are supposed to be provided by QEMU only. s390 needs some extra love as it carries redefinitions from kernel headers.

When Linux reboots an e500 VM, it writes to a magic register in the "global-utilities" device indicated by the device tree. We were not emulating that device so far, rendering the VM reboot-less. This patch implements that device with only the reboot functionality implemented and adds it to the device tree. With this patch applied, I can successfully reboot a -M mpc8544ds VM.

2011-06-01virtio-9p: Use relative includes for files in hwStefan Weil
Commit 353ac78d495ef976242abd868f68d78420861c2c moved the files without fixing the include paths. It used a modified CFLAGS to add hw to the include search path, but this breaks builds where the user wants to set special CFLAGS. Long include paths also increase compilation time. Therefore this patch removes the special CFLAGS for virtio and fixes the include statements by using relative include paths. v2: Remove special CFLAGS. v3: Update needed for latest QEMU.

2011-05-08xen: Introduce the Xen mapcacheJun Nakajima
On IA32 host or IA32 PAE host, at present, generally, we can't create an HVM guest with more than 2G memory, because generally it's almost impossible for Qemu to find a large enough and consecutive virtual address space to map an HVM guest's whole physical address space. The attached patch fixes this issue using dynamic mapping based on little blocks of memory. Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the lock option, so mapcache will not unmap these ram_ptr. Blocks that do not belong to the RAM, but usually to a device ROM or to a framebuffer, are handled in a separate function. So the whole RAMBlock can be map.
