PPC: E500: Populate L1CFG0 SPR

When running Linux on e500 with powersave-nap enabled, Linux tries to
read out the L1CFG0 register and calculates some things from it. Passing
0 there ends up in a division by 0, resulting in -1, resulting in badness.

qcow: Use bdrv functions to replace file operation

Since common file operation functions lack of error detection and use
much more I/O syscalls, so change them to bdrv series functions and
reduce I/O request.

12 years agoblock/vdi: Zero unused parts when allocating a new block (fix #919242)
Stefan Weil [Sat, 21 Jan 2012 12:54:24 +0000 (13:54 +0100)]
block/vdi: Zero unused parts when allocating a new block (fix #919242)

The new block was filled with zero when it was allocated by g_malloc0,
but when it was reused later and only partially used, data from the
previously allocated block were still present and written to the new
block.

This caused the problems reported by bug #919242
(https://bugs.launchpad.net/qemu/+bug/919242).

Now the unused parts of the new block which are before and after the data
are always filled with zero, so it is no longer necessary to zero the whole
block with g_malloc0.

I also updated the copyright comment.

blockdev: make image streaming safe across hotplug

Unplugging a storage interface like virtio-blk causes the host block
device to be deleted too.  Long-running operations like block migration
must take a DriveInfo reference to prevent the BlockDriverState from
being freed.  For image streaming we can do the same thing.

Note that it is not possible to acquire/release the drive reference in
block.c where the block job functions live because
drive_get_ref()/drive_put_ref() are blockdev.c functions.  Calling them
from block.c would be a layering violation - tools like qemu-img don't
even link against blockdev.c.
