The virtio pstore driver provides interface to the pstore subsystem so
that the guest kernel's log/dump message can be saved on the host
machine. Users can access the log file directly on the host, or on the
guest at the next boot using pstore filesystem. It currently deals with

Michael,
I realize this patch fell through the cracks while I was away... the various
reviews seemed to indicate there was a consensus to have this in 2.7 though.
Do you have an opinion whether QEMU needs this or not ?
Cc'ing Peter in case it is acceptable to apply the patch this late.
Cheers.
When I tried to make a change to the file hw/misc/macio/cuda.c, the make
command would not detect the changes. I would have to delete the cuda.o file to
make the changes actually compile.

Now that we are using real HW ids for the cores in PowerNV chips, we

This will be used to build real HW ids for the cores and enforce some

On PowerNV, CPU ids start at 0x8 or 0x20, we don't have a CPU 0

Initialization of memory backends may take a while when
prealloc=yes is used, depending on their size. Initializing
memory backends before chardevs may delay the creation of monitor
sockets, and trigger timeouts on management software that waits
until the monitor socket is created by QEMU. See, fo

smp_read_barrier_depends() should be used only if you are reading
dependent pointers which are shared. Here 'bh' is a local variable and
dereferencing it will always be ordered after loading 'bh', i.e.,
bh->next will always be ordered after fetching bh.
This patch removes the barrier and adds a co
