In 3.12 I changed audio to be enabled by default,
but you still had to turn it on via xrandr. This
was confusing to users so change it to minic the
previous behavior:
- audio option is set to -1 (auto) by default which is
the current 3.12 behavior (audio is enabled but requires
xrandr to turn it on).
- if audio = 1, the audio is enabled without needing
to mess with xrandr (previous behavior)
- audio = 0 disables audio
It retains the new feature of allowing the user to enable
audio on the fly with xrandr, but turns audio on
automatically if radeon.audio=1 is set which is what
most users expect.

Toshiaki Makita says:
====================
bridge: Fix problems around the PVID
There seem to be some undesirable behaviors related with PVID.
1. It has no effect assigning PVID to a port. PVID cannot be applied
to any frame regardless of whether we set it or not.
2. FDB entries learned via frames applied PVID are registered with
VID 0 rather than VID value of PVID.
3. We can set 0 or 4095 as a PVID that are not allowed in IEEE 802.1Q.
This leads interoperational problems such as sending frames with VID
4095, which is not allowed in IEEE 802.1Q, and treating frames with VID
0 as they belong to VLAN 0, which is expected to be handled as they have
no VID according to IEEE 802.1Q.
Note: 2nd and 3rd problems are potential and not exposed unless 1st problem
is fixed, because we cannot activate PVID due to it.
This is my analysis for each behavior.
1. We are using VLAN_TAG_PRESENT bit when getting PVID, and not when
adding/deleting PVID.
It can be fixed in either way using or not using VLAN_TAG_PRESENT,
but I think the latter is slightly more efficient.
2. We are setting skb->vlan_tci with the value of PVID but the variable
vid, which is used in FDB later, is set to 0 at br_allowed_ingress()
when untagged frames arrive at a port with PVID valid. I'm afraid that
vid should be updated to the value of PVID if PVID is valid.
3. According to IEEE 802.1Q-2011 (6.9.1 and Table 9-2), we cannot use
VID 0 or 4095 as a PVID.
It looks like that there are more stuff to consider.
- VID 0:
VID 0 shall not be configured in any FDB entry and used in a tag header
to indicate it is a 802.1p priority-tagged frame.
Priority-tagged frames should be applied PVID (from IEEE 802.1Q 6.9.1).
In my opinion, since we can filter incomming priority-tagged frames by
deleting PVID, we don't need to filter them by vlan_bitmap.
In other words, priority-tagged frames don't have VID 0 but have no VID,
which is the same as untagged frames, and should be filtered by unsetting
PVID.
So, not only we cannot set PVID as 0, but also we don't need to add 0 to
vlan_bitmap, which enables us to simply forbid to add vlan 0.
- VID 4095:
VID 4095 shall not be transmitted in a tag header. This VID value may be
used to indicate a wildcard match for the VID in management operations or
FDB entries (from IEEE 802.1Q Table 9-2).
In current implementation, we can create a static FDB entry with all
existing VIDs by not specifying any VID when creating it.
I don't think this way to add wildcard-like entries needs to change,
and VID 4095 looks no use and can be unacceptable to add.
Consequently, I believe what we should do for 3rd problem is below:
- Not allowing VID 0 and 4095 to be added.
- Applying PVID to priority-tagged (VID 0) frames.
Note: It has been descovered that another problem related to priority-tags
remains. If we use vlan 0 interface such as eth0.0, we cannot communicate
with another end station via a linux bridge.
This problem exists regardless of whether this patch set is applied or not
because we might receive untagged frames from another end station even if we
are sending priority-tagged frames.
This issue will be addressed by another patch set introducing an additional
egress policy, on which Vlad Yasevich is working.
See http://marc.info/?t=137880893800001&r=1&w=2 for detailed discussion.
Patch set follows this mail.
The order of patches is not the same as described above, because the way
to fix 1st problem is based on the assumption that we don't use VID 0 as
a PVID, which is realized by fixing 3rd problem.
(1/4)(2/4): Fix 3rd problem.
(3/4): Fix 1st problem.
(4/4): Fix 2nd probelm.
v2:
- Add descriptions about the problem related to priority-tags in cover letter.
- Revise patch comments to reference the newest spec.

We currently set the value that variable vid is pointing, which will be
used in FDB later, to 0 at br_allowed_ingress() when we receive untagged
or priority-tagged frames, even though the PVID is valid.
This leads to FDB updates in such a wrong way that they are learned with
VID 0.
Update the value to that of PVID if the PVID is applied.

We are using the VLAN_TAG_PRESENT bit to detect whether the PVID is
set or not at br_get_pvid(), while we don't care about the bit in
adding/deleting the PVID, which makes it impossible to forward any
incomming untagged frame with vlan_filtering enabled.
Since vid 0 cannot be used for the PVID, we can use vid 0 to indicate
that the PVID is not set, which is slightly more efficient than using
the VLAN_TAG_PRESENT.
Fix the problem by getting rid of using the VLAN_TAG_PRESENT.

Once the machine gets to a certain point in the suspend process, we
expect the GPU to be idle. If it is not, we might corrupt memory.
Empirically (with an early version of this patch) we have seen this is
not the case. We cannot currently explain why the latent GPU writes
occur.
In the technical sense, this patch is a workaround in that we have an
issue we can't explain, and the patch indirectly solves the issue.
However, it's really better than a workaround because we understand why
it works, and it really should be a safe thing to do in all cases.
The noticeable effect other than the debug messages would be an increase
in the suspend time. I have not measure how expensive it actually is.
I think it would be good to spend further time to root cause why we're
seeing these latent writes, but it shouldn't preclude preventing the
fallout.
NOTE: It should be safe (and makes some sense IMO) to also keep the
VALID bit unset on resume when we clear_range(). I've opted not to do
this as properly clearing those bits at some later point would be extra
work.

Revert some changes done in 774638386826621c984ab6994439f474709cac5e.
Revert all changes done in hidinput_calc_abs_res as it mistakingly used
"Unit" item exponent nibbles to affect resolution value. This wasn't
breaking resolution calculation of relevant axes of any existing
devices, though, as they have only one dimension to their units and thus
1 in the corresponding nible.
Revert to reading "Unit Exponent" item value as a signed integer in
hid_parser_global to fix reading specification-complying values. This
fixes resolution calculation of devices complying to the HID standard,
including Huion, KYE, Waltop and UC-Logic graphics tablets which have
their report descriptors fixed by the drivers.
Explanations follow.
There are two "unit exponents" in HID specification and it is important
not to mix them. One is the global "Unit Exponent" item and another is
nibble values in the global "Unit" item. See 6.2.2.7 Global Items.
The "Unit Exponent" value is just a signed integer and is used to scale
the integer resolution unit values, so fractions can be expressed.
The nibbles of "Unit" value are used to select the unit system (nibble
0), and presence of a particular basic unit type in the unit formula and
its *exponent* (or power, nibbles 1-6). And yes, the latter is in two
complement and zero means absence of the unit type.
Taking the representation example of (integer) joules from the
specification:
[mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7
the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the
"Unit" value would be 0xE121, signifying:
Nibble Part Value Meaning
----- ---- ----- -------
0 System 1 SI Linear
1 Length 2 Centimeters^2
2 Mass 1 Grams
3 Time -2 Seconds^-2
To give the resolution in e.g. hundredth of joules the "Unit Exponent"
item value should have been -9.
See also the examples of "Unit" values for some common units in the same
chapter.
However, there is a common misunderstanding about the "Unit Exponent"
value encoding, where it is assumed to be stored the same as nibbles in
"Unit" item. This is most likely due to the specification being a bit
vague and overloading the term "unit exponent". This also was and still
is proliferated by the official "HID Descriptor Tool", which makes this
mistake and stores "Unit Exponent" as such. This format is also
mentioned in books such as "USB Complete" and in Microsoft's hardware
design guides.
As a result many devices currently on the market use this encoding and
so the driver should support them.
