These series are a supplement to the ones I sent earlier. They add an
owner to all memory regions that belong to a qdev-ified device. These
patches are *not* automatically generated! (The bulk change in this
morning's patches was generated by sed, instead).
The ownership API is easier to use than in my previous attempt; this
series is the price to pay.
Patch 1 is trivial; patches 2-11 add an owner argument, whenever needed,
to functions that create memory regions and do not already take an object.
The last 12 patches are the ones that are difficult to review. I
reviewed them myself as follows, starting from a "ddd" file that has
the 12 patches squashed.
Due to additional dependencies on Jan's patches, it's probably more
practical if you just start from the iommu branch of my github repo.
1) Use
grep memory_region_init ddd|grep -v ,.*,
which gave results in four files:
hw/block/pflash_cfi01.c
hw/i386/kvm/pci-assign.c
hw/misc/vfio.c
hw/pci/pci.c
reviewed those manually and dropped the hunks from the "ddd" file.
2) Run this script
awk '{
if (/diff/) { file = $3; sub(/^a\//, "", file) }
else if (/^@@/) { f = $3; gensub(/^+(.*),.*/, "\\1", f); line = f - 1 }
if (/^[ -+]/) line++;
if (/^\+.*memory_region/) {
sub(/\(/, " (", $2); $0 = $0;
print file, line, $2, $4
}
}' ddd | grep -v OBJECT
The output lines are in the format (file, line, function called, second
argument)
hw/alpha/typhoon.c 753 TyphoonState s
(file, line, type, variable name). This pass gave results for these files:
hw/acpi/core.c (uses memory_region_owner)
hw/cpu/icc_bus.c (receives an Object *)
hw/dma/xilinx_axidma.c (receives an Object *)
hw/ide/macio.c (receives an Object *)
hw/input/pckbd.c (arithmetic in the first argument, 2 occurrences)
hw/isa/pc87312.c (receives an Object *)
Reviewed acpi/core.c and input/pckbd.c manually, removed them from the
"ddd" file. Checked that the fourth argument is always of the shape
"OBJECT(foo)".
3) put this in get_var_type.awk
BEGIN {
var_re = "([A-Za-z_][A-Za-z_0-9]*)\\s*\\*\\s*" var "\\>\\s*[,=;)]"
}
match($0, var_re, subs) {
type = subs[1]
}
NR == line {
print FILENAME, line, type, var
}
and run this script, similar to the one in step 2:
awk '{
if (/diff/) { file = $3; sub(/^a\//, "", file) }
else if (/^@@/) { f = $3; gensub(/^+(.*),.*/, "\\1", f); line = f - 1 }
if (/^[ -+]/) line++;
if (/^\+.*memory_region/) {
sub(/\(/, " (", $2); $0 = $0;
sub(/^OBJECT\(/, "", $4)
sub(/,$/, "", $4)
sub(/\)$/, "", $4)
print "awk -fget_var_type.awk", "-vline="line, "-vvar="$4, file
}
}' ddd | sh > fff
The "fff" file has output like this:
hw/alpha/typhoon.c 753 TyphoonState s
(file, line, type, variable name)
4) Run
awk '{print $3}' fff|sort -u|tee ggg
and eyeballed it for weird things.
5) Reviewed the output of this:
for i in `cat ggg` ; do
git grep -A1 -E '^(typedef )?struct '$i || echo "$i ???"
echo --
done
... checking files by hand if the definition of the struct was not
obvious from the "git grep" output.
This found 4 bugs passing as the owner NE2000State, AHCIDevice,
I82378State and DebugconState. It also found one false positive
(SerialState for hw/char/escc.c). All of these are of course gone in
this submission. After finding these bugs, I redid all the steps.
This time, before step 5 I limited the scope using
for i in `awk '{print $3}' fff|sort -u` ; do
git grep --quiet DEFINE_PROP_.*'\b'$i'\b' || echo $i
done > ggg
after checking that it would not cause any false negative.
