[PATCH 1/5] ALSA: hda - Add fixup_forced flag

[Hui Wang]

From: David Henningsson <david.henningsson@canonical.com>

The "fixup_forced" flag will indicate whether a specific fixup
(or nofixup) has been set by the user, to override the driver's
default.
This flag will help future patches.

[PATCH 2/5] ALSA: hda - Add a new quirk match based on default pin configuration

[Hui Wang]

From: David Henningsson <david.henningsson@canonical.com>

Normally, we match on pci ssid only. This works but needs new code
for every machine. To catch more machines in the same quirk, let's add
a new type of quirk, where we match on
 1) PCI Subvendor ID (i e, not device, just vendor)
 2) Codec ID
 3) Pin configuration default

If all these three match, we could be reasonably certain that the
quirk should apply to the machine even though it might not be the
exact same device.

[PATCH 4/5] ALSA: hda - drop def association and sequence from pinconf comparing

[Hui Wang]

A lot a machine have the same codec, but they have different default
pinconf setting just because the def association and sequence is
different, as a result they can't share a hda_pintbl[], to overcome
it, we don't compare def association and sequence in the pinconf
matching.

In general, when you submit a patch, *you* need to sign off the patch
in addition.  It's no big problem in this case since I already got the
same patches from David, though.

In anyway, I applied all patches now.  Thanks.

Uhm, really? Alex, does this seem reasonable from a BIOS perspective, i 
e, that BIOS people normally would set def association and sequence 
different while leaving everything else unchanged?

Shouldn't then 10 lines be removed from alc269_fixup_tbl? Right now only 
two lines are removed.

I mean the 10 new Dell laptops which have not been in the Linux kernel yet.

Please see a new bug #1321179, there are 7 laptops in this bug, In the past, we need to add 7 lines to fix them, but now all of them can be fixed by this patch.


Removing the existing lines is the next step plan.

Re: [PATCH 4/5] ALSA: hda - drop def association and sequence from pinconf comparing

[Alex Hung]

Hi David,

BIOS today implements verbtable which is provided by codec vendor
based on hardware design, and it is indeed not uncommon that the
verbtable includes used pin only and leaves unused pins untouched.

Sure, but those unused pins would then have the same default value that 
the codec initializes it with.

Also, it wouldn't be uncommon for BIOS (or codec vendors) to use the 
same verbtable for several machines if they share the same audio hardware.

But none of this explains why anyone would just change def association 
and sequence value between machines? It makes no sense.

So far, I met one example for this case:

the Dell laptops with the same 0x10ec0255 codec,

On some machines:
pin 0x12, 0x90a60170
pin 0x14, 0x90170120
pin 0x21, 0x02211030

On another machine:
pin 0x12, 0x90a60140
pin 0x14, 0x90170110
pin 0x21, 0x02211020


The def config of the rest pins are same.

Hui.

If there is only one example (and only two different options), I think 
we should revert this patch and use two different pin-matching quirks 
instead.

After all, ignoring the def assoc/sequence values also means a greater 
risk of catching unwanted machines. Better err on the more careful side.

This is IMO, what do others think?
