2011-04-19The "temp" will be used later. So it has to be calculated correctly.Zheng Bao
Comment by Peter, The variable name "temp" unfortunately does not explain what the value is. The commit message also does not have hints. Hopefully in the future it's possible to also use a brief moment to improve the clarity of the code, while it is already being fixed for some other reason. Ie. fixing up variable names, writing particularly informative commit messages, or of course both at the same time! :) Signed-off-by: Zheng Bao <zheng.bao@amd.com> Acked-by: Marc Jones <marcj303@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6517 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2011-03-08Enable mahogany_fam10 and Kino family 10h to run the SB HT link at the ↵Scott Duplichan
expected HT3 frequency and width by matching the BUID swap list to the production BIOS. In addition, the BUID swap list has been moved into the project-specific file romstage.c for the other 13 AMD family 10h projects as well. For projects using a desktop AMD family 10h processor, pasting in the mahogany_fam10 swap list will likely allow HT3 operation. This should be confirmed on real hardware before commiting any swap list change. A different swap list will be needed for server projects. For serengeti_cheetah_fam10, a reference BIOS swap list to try is: 0x00, 0x0A, 0x00, 0x06, 0xFF, 0x0A, 0x06, 0xFF. The patch makes these changes: 1) Remove the BUID swap list from ht_wrapper.c and put it in each of 15 romstage.c files where it is used (AMD family 10h projects). 2) Add a prototype to amdfam10.h. 3) Modify the swap list and test in real hardware for mahogany_fam10 and kino family 10h and confirm HT3 operation for the SB link. Abuild tested.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. In fact I changed coreDelay before deleting the code in fidvid that called it. But there're still a couple of calls from src/northbridge/amd/amdmct/wrappers/mcti_d.c Since the comment encouraged fixing something, I parametrized it with the delay time in microseconds and paranoically tried to avoid an overflow at pathological moments.

2011-02-28Improving BKDG implementation of P-states,Xavi Drudis Ferran
CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Looking at BKDG the process for updating Pstate Nb vid after warn reset seemed more similar to the codethat was there fo pvi than the one for svi, so I called the pvi function passing a pvi/svi flag. I don't find documentation on why should UpdateSinglePlaneNbVid() be called in PVI, but since I can't test it, I leave it as it was. This patch showed some progress beyond fidvid in my boar,d but only sometimes, most times it just didn't work.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Factor out some common expressions. Add an error message when coreboots hangs waiting for a pstate that never comes (it happened to me), and throw some paranoia at it for good mesure. If I understood BKDG fam10 CPUs never need a software initiated vid transition, because the hardware knows what to do when you just request a Pstate change if the cpu is properly configured. In fact unifying a little what PVI and SVI do was better for my board (SVI). So I drop transitionVid, which I didn't understand either (why did it have a case for PVI if it is never called for PVI ? Why did the PVI case distinguigh cpu or nb when PVI is theoretically single voltage plane ? ).
