[LinuxBIOS] PS2 keyboard not working on ASUS A8N5X (K8/CK804/IT8712F)

[Robert Millan]

Hi,

After commenting this with Uwe on IRC, he said I should ask to the list to
see if someone knows what's going on.

I'm running LB with some patches (combined with fixes sent by Uwe and Rudolf),
plus some PNP adjustments for the keyboard/game/midi ports on my ASUS A8N5X
(K8/CK804/IT8712F), and keyboard is not working neither from FILO nor Linux.

Find attached:

- combined diff of the changes I have relative to svn
  - minicom capture log (using loglevel 11)
  - "lspci -nnv" and "lspnp -v" output

Some hint would be appreciated.  TIA!

Let me just ask the very dumb question.  Does the keyboard work with the
stock BIOS?  Have you tried the stock BIOS since you had this problem? 
Just a sanity check.

Yes :-)

I switch LB and stock BIOS all the time, because from LB I don't get network,
so I can't scp new images for re-flash.

Please also attach a dmesg (or minicom capture log) for Linux under the
proprietary BIOS.

I assume you have a good reason, but why are you changing the it8712f 
pnp device numbers? I am not positive how this works, but I think 
changing 2e.0 to 2e.7 means that you are trying to program the it8712f 
logical device 7 with floppy settings.
http://www.tranzistoare.ro/datasheets/1150/495234_DS.pdf

IRQ routing/polarity/mask issues? Check mptable.c and irq_tables.c.

You can check the keyboard controller input buffer to see if a keystroke 
is in there. Then you would know that interrupt isn't getting through.

Do you have serial console working and does keyboard work there? That 
would tell you if interrupts are making it from the SIO.

Hope this helps.

The changes were mostly part of the patch Uwe sent me (for his slightly
different board).  I also changed keyboard (s/2e.5/2e.a/), midi (s/2e.8/2e.b/)
and game port (s/2e.9/2e.c/) while trying to match with lspnp output:

00:0a PNP0303 IBM enhanced keyboard (101/102-key, PS/2 mouse support)
  00:0b PNPb006 MPU401 compatible
  00:0c PNPb02f Joystick/Game port

Is this correct?
> IRQ routing/polarity/mask issues? Check mptable.c and irq_tables.c.

I see that they print these debug messages:

Writing IRQ routing tables to 0xf0000...done.
  Wrote the mp table end at: 00000020 - 00000140

I'm not sure if I can make sense of this.  Should I poke at the contents
in these addresses?

How would I do that, with a userspace program using inb()/outb() ?

Yes, that works.

Thank you

I guess Uwe would need to answer this. I must not understand it correctly.

You can get more info here:
http://linuxbios.org/Glossary#MPTable
http://linuxbios.org/Glossary#PIRQ

I don't recall where, but there are some guides on dumping the tables 
from the PCBIOS somewhere.

Yes,
// check if there is a keystroke that hasn't been serviced and see what 
it is.
status = inb(0x64);
if ((status & 0x1))
    scancode = inb(0x60);

if the KBC controller is being serviced it is unlikely that you will 
catch a character in the output buffer. If the KBC isn't initialized 
correctly you might not get a character either.

Interesting that the SIO serial interrupt works and the the keyboard one 
doesn't. I am not sure what that means.

Exactly what superio model do you have?

Yes, but serial loses continuous runs of characters. That might be a
problem on the receiving side, though.

IT8712F-A.  Uwe has a different one, I think.  Perhaps I should start with the
Config.lb pnp setup from pristine svn and adapt that to my pnp layout instead
of using his patched version ?

Start from a Config.lb which uses exactly the superio you have. If that
is not possible, read the datasheet of your superio and modify your
Config.lb so that it matches the datasheet.

Please be also aware that the IT8712F has a "keyboard controller with 2
kb programmable ROM" which might need special handling.

If you have problems downloading the datasheet from ITE (the download
may stall) tell me and I'll send it to you privately.

the ITE datasheet looks quite informative. Is it all you get / need to 
do the job ?

my ebay seller of the A8N-E keeps me waiting for a week now, though I 
got all other components handy ! I hope to boot LB any day now !  --Q
