The SCSI emulation in the Linux NVMe driver really wants to know if a device has a volatile write cache. Given that qemu has moved away from a model where we report the backing store WCE bit to one where the WCE bit is supposed to be part of the migratable guest-visible state we always return 1 here.

Windows seems to send two separate calls to NVMe controller configuration. The first sends configuration info and the second the enable bit. I couldn't enable the Windows 8.1 in-box NVMe driver with base Qemu. I made the following change to store the configuration data and then handle enable and NVMe driver works on Windows 8.1. I am not a Windows expert and I'm not entirely sure this is the correct approach. I'm offering it for anyone who wishes to use NVMe on Windows 8.1 using Qemu. I have tested this change with Linux and Windows guests with NVMe devices.

geometry: hd_geometry_guess function autodetects the drive geometry. This patch adds a block backend call, that probes the backing device geometry. If the inner driver method is implemented and succeeds (currently only for DASDs), the blkconf_geometry will pass-through the backing device geometry. Otherwise will fallback to old logic. blocksize: This patch initializes blocksize properties to 0. In order to set the property a blkconf_blocksizes was introduced. If user didn't set physical or logical blocksize, it will retrieve its value from a driver (only succeeds for DASD), otherwise it will set default 512 value. The blkconf_blocksizes call was added to all users of BlkConf.

Device models should access their block backends only through the block-backend.h API. Convert them, and drop direct includes of inappropriate headers. Just four uses of BlockDriverState are left: * The Xen paravirtual block device backend (xen_disk.c) opens images itself when set up via xenbus, bypassing blockdev.c. I figure it should go through qmp_blockdev_add() instead. * Device model "usb-storage" prompts for keys. No other device model does, and this one probably shouldn't do it, either. * ide_issue_trim_cb() uses bdrv_aio_discard() instead of blk_aio_discard() because it fishes its backend out of a BlockAIOCB, which has only the BlockDriverState. * PC87312State has an unused BlockDriverState[] member. The next two commits take care of the latter two. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Reviewed-by: NMax Reitz <mreitz@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This is the next step for decoupling block accounting functions from BlockDriverState. In a future commit the BlockAcctStats structure will be moved from BlockDriverState to the device models structures. Note that bdrv_get_stats was introduced so device models can retrieve the BlockAcctStats structure of a BlockDriverState without being aware of it's layout. This function should go away when BlockAcctStats will be embedded in the device models structures.

g_new(T, n) is safer than g_malloc(sizeof(*v) * n) for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. Perhaps a conversion to g_malloc_n() would be neater in places, but that's merely four years old, and we can't use such newfangled stuff. This commit only touches allocations with size arguments of the form sizeof(T), plus two that use 4 instead of sizeof(uint32_t). We can make the others safe by converting to g_malloc_n() when it becomes available to us in a couple of years.
