2009-01-22qcow2 format: keep 'num_free_bytes', and show it upon 'info blockstats' (Uri ↵aliguori
Lublin) 'num_free_bytes' is the number of non-allocated bytes below highest-allocation. It's useful, together with the highest-allocation, to figure out how fragmented the image is, and how likely it will run out-of-space soon. For example when the highest allocation is high (almost end-of-disk), but many bytes (clusters) are free, and can be re-allocated when neeeded, than we know it's probably not going to reach end-of-disk-space soon. Added bookkeeping to block-qcow2.c Export it using BlockDeviceInfo Show it upon 'info blockstats' if BlockDeviceInfo exists Signed-off-by: Uri Lublin <uril@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6407 c046a42c-6fe2-441c-8c8c-71466251a162

2009-01-22block-qcow2: keep highest allocated byte (Uri Lublin)aliguori
We want to know the highest written offset for qcow2 images. This gives a pretty good (and easy to calculate) estimation to how much more allocation can be done for the block device. It can be usefull for allocating more diskspace for that image (if possible, e.g. lvm) before we run out-of-disk-space Signed-off-by: Uri Lublin <uril@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6404 c046a42c-6fe2-441c-8c8c-71466251a162

2009-01-22Vectored block device API (Avi Kivity)aliguori
Most devices that are capable of DMA are also capable of scatter-gather. With the memory mapping API, this means that the device code needs to be able to access discontiguous host memory regions. For block devices, this translates to vectored I/O. This patch implements an aynchronous vectored interface for the qemu block devices. At the moment all I/O is bounced and submitted through the non-vectored API; in the future we will convert block devices to natively support vectored I/O wherever possible.

2009-01-22Add target memory mapping API (Avi Kivity)aliguori
Devices accessing large amounts of memory (as with DMA) will wish to obtain a pointer to guest memory rather than access it indirectly via cpu_physical_memory_rw(). Add a new API to convert target addresses to host pointers. In case the target address does not correspond to RAM, a bounce buffer is allocated. To prevent the guest from causing the host to allocate unbounded amounts of bounce buffer, this memory is limited (currently to one page).

Removing the assumption about a single graphic console made get_graphic_console return NULL when called by vga_screen_dump. In this case returning NULL is correct but since NULL is not handled in qemu_console_resize it causes a segmentation fault. Just returning immediately from qemu_console_resize is sufficient to fix the problem.

2009-01-21fix curses interface (Stefano Stabellini)aliguori
Hi all, this patch fixes the curses interface: when we switch from one console to another we need to change the displaystate width and height even though in the curses case the backing buffer remains of the same size. I am also putting back the call to text_console_resize in text_console_invalidate so that resizeable text consoles can be properly handled.

2009-01-17Remove unused info_str parameter to pcnet_common_init()blueswir1
I noticed that pcnet_common_init() takes an unused 'info_str' parameter, added in r2142. Since then, we always pass "pcnet" to register_savevm() (and never "lance"). Note that r6218 changed vc->info_str to "lance" for sun4m emulation. On the assumption that it's not needed, this patch removes the parameter. If reverting the change in r2142, and registering with "lance" would be preferable, I can submit a patch to do so.
