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.

Access register mode is one of the modes that control dynamic address
translation. In this mode the address space is specified by values of
the access registers. The effective address-space-control element is
obtained from the result of the access register translation. See
the "Access-Register Introduction" section of the chapter 5 "Program
Execution" in "Principles of Operations" for more details.
When the CPU is in AR mode, the s390_cpu_virt_mem_rw() function must
know which access register number to use for address translation.
This patch does several things:
- add new parameter 'uint8_t ar' to that function
- decode ar number from intercepted instructions
- pass the ar number to s390_cpu_virt_mem_rw(), which in turn passes it
to the KVM_S390_MEM_OP ioctl.

Somehow these GPUs manage not to respond to a PCI bus reset, removing
our primary mechanism for resetting graphics cards. The result is
that these devices typically work well for a single VM boot. If the
VM is rebooted or restarted, the guest driver is not able to init the
card from the dirty state, resulting in a blue screen for Windows
guests.
The workaround is to use a device specific reset. This is not 100%
reliable though since it depends on the incoming state of the device,
but it substantially improves the usability of these devices in a VM.

This is an impossible error path due to the fact that we're reading a
kernel provided, rather than user provided link, which will certainly
always fit in PATH_MAX. Currently it returns a fixed 26 char path
plus %d group number, which typically maxes out at double digits.
However, the caller of the initfn certainly expects a less-than zero
return value on error, not just a non-zero value. Therefore we
should correct the sign here.

In an analysis by Laszlo, the resulting type of our calculation for
the end of the MSI-X table, and thus the start of memory after the
table, is uint32_t. We're therefore not correctly preventing the
corner case overflow that we intended to fix here where a BAR >=4G
could place the MSI-X table to end exactly at the 4G boundary. The
MSI-X table offset is defined by the hardware spec to 32bits, so we
simply use a cast rather than changing data structure types. This
scenario is purely theoretically, typically the MSI-X table is located
at the front of the BAR.

Of the block devices that poked into -drive options via drive_get_next,
m25p80 was the only one who also did not attach itself to the BlockBackend.
Since sd does it, and all other devices go through a "drive" property,

ffs() cannot be replaced with ctz32() when the argument might be zero,
because ffs(0) returns 0 while ctz32(0) returns 32.
The ffs(3) call in sd_normal_command() is a special case though. It can
be converted to ctz32() + 1 because the argument is never zero:

The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.

ram_addr_t is an internal interface, everyone should go through
MemoryRegion. Clean it up by making rom_add_blob return a
MemoryRegion* and using the new qemu_ram_resize infrastructure.

Switch all the uses of ld/st*_phys to address_space_ld/st*,
except for those cases where the address space is the CPU's
(ie cs->as). This was done with the following script which
generates a Coccinelle patch.
A few over-80-columns lines in the result were rewrapped by
hand where Coccinelle failed to do the wrapping automatically,
as well as one location where it didn't put a line-continuation
'\' when wrapping lines on a change made to a match inside
a macro definition.

Rather than retaining io_mem_read/write as simple wrappers around
the memory_region_dispatch_read/write functions, make the latter
public and change all the callers to use them, since we need to
touch all the callsites anyway to add MemTxAttrs and MemTxResult
support. Delete io_mem_read and io_mem_write entirely.
(All the callers currently pass MEMTXATTRS_UNSPECIFIED
and convert the return value back to bool or ignore it.)

A VM supports only one balloon device, but due to several changes
in infrastructure the error message got messed up when trying
to add a second device. Fix it.
Before this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Another balloon device already registered
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Adding balloon handler failed
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
Another balloon device already registered
Adding balloon handler failed
Device 'virtio-balloon-pci' could not be initialized
QMP:
{ "execute": "device_add", "arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Adding balloon handler failed"
}
}
After this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Only one balloon device is supported
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
(qemu) device_add virtio-balloon-pci,id=balloon0
Only one balloon device is supported
Device 'virtio-balloon-pci' could not be initialized
(qemu)
QMP:

"arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Only one balloon device is supported"
