Re: [COMMIT] freebios2 How much have I broken?

Eric,

The same.

One Clue: Even I do the reverse scan, if I enable the hard_reset in the
misc_control.c. After the reset and successful scan the 8131/8111, it will
hang when scan the 8151.

Regards

YH

A) the reverse scan works and that is good.

Why?  This is what I am trying to understand.  It doesn't make sense
especially as I already did that, earlier.  The resets to get the
hypertransport settings to take effect.  I can see those depending on
the amd8111.

Have you tried the small subroutine change I sent?

Does this mean when the code looks as the device on bus 1 it sees
0xffff for the vendor and device id.

Hmm. Thanks for looking at this.

I wonder if we might not have link speed/width configuration issues.

The code should be computing it properly but...

That is certainly what the second case sounds like.  I had forgotten
that i need to delay the reset until we are done with all of the hypertransport
chains.

Hmm. I wonder if I am tripping up an 8151 errata.
