lsi_bad_phase has a bug in the choice of pmjad1/pmjad2. This does
not matter with Linux guests because it uses just one routine for
both, but it breaks Windows 64-bit guests. This is the text
from the spec:
"[The PMJCTL] bit controls which decision mechanism is used
when jumping on phase mismatch. When this bit is cleared the
LSI53C895A will use Phase Mismatch Jump Address 1 (PMJAD1) when
the WSR bit is cleared and Phase Mismatch Jump Address 2 (PMJAD2)
when the WSR bit is set. When this bit is set the LSI53C895A will
use jump address one (PMJAD1) on data out (data out, command,
message out) transfers and jump address two (PMJAD2) on data in
(data in, status, message in) transfers."
Which means:
CCNTL0.PMJCTL
0 SCNTL2.WSR = 0 PMJAD1
0 SCNTL2.WSR = 1 PMJAD2
1 out PMJAD1
1 in PMJAD2
In qemu, what you get instead is:
CCNTL0.PMJCTL
0 out PMJAD1
0 in PMJAD2 <<<<<
1 out PMJAD1
1 in PMJAD1 <<<<<
Considering that qemu always has SCNTL2.WSR cleared, the two marked cases
(corresponding to phase mismatch on input) are always jumping to the
wrong PMJAD register. The patch implements the correct semantics.

The MASTER_DISABLE bit (aka mask-all) masks all the interrupts.
According to Sun-4M System Architecture
"The level–15 interrupt sources [...] are maskable with the Interrupt Target
Mask Register. While these interrupts are considered ’non–maskable’ within
the SPARC IU, a mask capability is provided to allow the boot firmware
to establish a basic environment before receiving any level–15 interrupts,
which are non–maskable within SPARC. A mask–all bit is provided to allow
disabling of all external interrupts during change of the CIT."

Mapped mode stores extended attributes in the user space of the extended
attributes. Given that the user space extended attributes are available
to regular files only, special files are created as regular files on the
fileserver and appropriate mode bits are added to the extended attributes.
This method presents all special files and symlinks as regular files on the
fileserver while they are represented as special files on the guest mount.

Mapped mode stores extended attributes in the user space of the extended
attributes. Given that the user space extended attributes are available
to regular files only, special files are created as regular files on the
fileserver and appropriate mode bits are added to the extended attributes.
This method presents all special files and symlinks as regular files on the
fileserver while they are represented as special files on the guest mount.
Implemntation of symlink in mapped security model:
A regular file is created and the link target is written to it.
readlink() reads it back from the file.
On Guest/Client:
lrwxrwxrwx 1 root root 6 2010-05-11 12:20 asymlink -> afile
On Host/Fileserver:
-rw-------. 1 root root 6 2010-05-11 09:20 asymlink
afile
Under passthrough model, it just calls underlying symlink() readlink()
system calls are used.
Under both security models, client user credentials are changed
after the filesystem objec creation.

In the mapped security model, VirtFS server intercepts and maps
the file object create and get/set attribute requests. Files on the fileserver
will be created with VirtFS servers (QEMU) user credentials and the
client-users credentials are stored in extended attributes. On the request
to get attributes, server extracts the client-users credentials
from extended attributes and sends them to the client.

The new option is:
-fsdev fstype,id=myid,path=/share_path/,security_model=[mapped|passthrough]
-virtfs fstype,path=/share_path/,security_model=[mapped|passthrough],mnt_tag=tag
In the case of mapped security model, files are created with QEMU user
credentials and the client-user's credentials are saved in extended attributes.
Whereas in the case of passthrough security model, files on the
filesystem are directly created with client-user's credentials.

Setting the ID in pci_nic_init() is a blatant violation of the
DeviceState abstraction. Which even carries a comment advising
against this:
/* This structure should not be accessed directly. We declare it here
so that it can be embedded in individual device state structures. */
What's worse, it bypasses the code ensuring unique qdev IDs: "-device
virtio-net-pci,id=foo -net nic,id=foo -net nic,name=foo" happily
creates three qdevs with ID "foo". That's because qdev relies on
qemu_opts_create() to ensure unique IDs, but -net nic uses a different
QemuOptsList, which means id is in a different namespace. And its
name is not checked for uniqueness at all.
-net nic and pci_add are legacy. Use -device and device_add if you
want a NIC with a qdev ID.
This reverts what's still left of commit eb54b6dc "qdev: add id=
support for pci nics."

When mistakenly configuring two devices in the same PCI slot,
QEMU gives a not entirely obvious message about a 'devfn' being
in use:
$ qemu -device rtl8139 -device virtio-balloon-pci,bus=pci.0,addr=0x3
qemu-kvm: -device virtio-balloon-pci,bus=pci.0,addr=0x3: PCI: devfn 24 not available for virtio-balloon-pci, in use by rtl8139
The user does not configure 'devfn' numbers, they use slot+function.
Thus the error messages should be reported back to the user with that
same terminology rather than the internal QEMU terminology. This
patch makes it report:
$ qemu -device rtl8139 -device virtio-balloon-pci,bus=pci.0,addr=0x3
qemu: -device virtio-balloon-pci,bus=pci.0,addr=0x3.7: PCI: slot 3 function 0 not available for virtio-balloon-pci, in use by rtl8139
