Hi,
I've attempted to use the rs780 and sb800 code on a AM3 870 + SB850 board. Raminit seems to go okay, as does the first bits of ramstage. However, ramstage fails after the first two passes through rs780_enable(). It stalls in get_vid_did() reading PCI config space of device 2 (or 4). Also, the rs780 HT init code thinks the link should run at 200MHz, maybe that's related.
Attached is the diff, and console output there from. (Mainboard directory is a svn cp of bimini_fam10.)
rs780_htinit cpu_ht_freq=0. rs780_htinit: HT1 mode
]It looks it had problems getting the HT frequency from the CPU. Both ]sides have to agree on what is capable. You may need to look at the ]CPU HT code for a hint on why it reports what it does to the SB. ] ]Marc
Also remember that the family 10h swap list problem still exists. There are some old patches and discussion that might be useful. Here is an example:
