2011-07-21SPARC64: implement addtional MMU faults related to nonfaulting loadTsuneo Saito2-3/+30
This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.

2011-07-21SPARC64: implement MMU miss traps on nonfaulting loadsTsuneo Saito1-16/+20
Nonfaulting loads should raise fast_data_access_MMU_miss traps as normal loads do. It is up to the guest OS kernel that detect MMU misses on nonfaulting load instructions and make them complete without signaling.

2011-07-21SPARC64: fix fault status overwritten on nonfaulting loadTsuneo Saito1-6/+2
cpu_get_phys_page_nofault() calls get_physical_address() twice, that results in overwriting the fault status in the SFSR. We need this change in order for nonfaulting loads to raising MMU faults as normal loads do. Also removed the call to cpu_get_physical_page_desc() since we are going to modify nonfaulting loads raising MMU faults.

2011-07-21SPARC64: split cpu_get_phys_page_debug() from cpu_get_phys_page_nofault()Tsuneo Saito2-1/+16
This patch makes cpu_get_phys_page_debug() independent from cpu_get_phys_page_nofault() in advance of implementing nonfaulting load. This also modifies cpu_get_phys_page_nofault() to be compiled only on TARGET_SPARC64 because it is not required on SPARC32.

2011-07-19qcow2: Use Qcow2Cache in writeback mode during loadvm/savevmKevin Wolf3-11/+41
In snapshotting there is no guest involved, so we can safely use a writeback mode and do the flushes in the right place (i.e. at the very end). This improves the time that creating/restoring an internal snapshot takes with an image in writethrough mode. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-07-19block: add bdrv_get_allocated_file_size() operationFam Zheng7-30/+96
qemu-img.c wants to count allocated file size of image. Previously it counts a single bs->file by 'stat' or Window API. As VMDK introduces multiple file support, the operation becomes format specific with platform specific meanwhile. The functions are moved to block/raw-{posix,win32}.c and qemu-img.c calls bdrv_get_allocated_file_size to count the bs. And also added VMDK code to count his own extents.

The return type of get_cluster_offset was an offset that use 0 to denote 'not allocated', this will be no longer true for flat extents, as we see flat extent file as a single huge cluster whose offset is 0 and length is the whole file length. So now we use int return value, 0 means success and otherwise offset invalid.

2011-07-18virtio-console: Prevent abort()s in case of host chardev closeAmit Shah1-1/+15
A host chardev could close just before the guest sends some data to be written. This will cause an -EPIPE error. This shouldn't be propagated to virtio-serial-bus. Ideally we should close the port once -EPIPE is received, but since the chardev interface doesn't return such meaningful values to its users, all we get is -1 for any kind of error. Just return 0 for now and wait for chardevs to return better error messages to act better on the return messages. Signed-off-by: Amit Shah <amit.shah@redhat.com>
