Question about Opteron UnitID register
by David Hendricks 25 Aug '03

25 Aug '03

I know you guys aren't AMD tech support, I was hoping someone could help me figure this problem out. In section 3.3.8 (page 35) of their BIOS and Kernel developers guide ( http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/260… ), they have a 32-bit UnitID register. The example given lists the lowest four bits as follows: 3-2: CPU1 Unit ID 1-2: CPU0 Unit ID Ok, so you could give CPU1, CPU2, and CPU3 a unique ID with two binary digits, but I thought we were supposed to be able to have eight (or more?) CPUs? Is there something obvious I'm missing? Is the CPU Unit ID the same as the NodeID, or different? Do these CPU Unit IDs even have to be unique for each CPU? I was thinking perhaps the CPU1 Unit ID is used only by a noncoherant device attached via Hypertransport link to what it thinks is CPU1 to differentiate the CPU it's attached to from CPU0. If this is true, is it necessary since the bootstrap processor, CPU0, is the only one with access to its northbridge and memory controller at this point? Sorry if all this is complete and utter nonsense, I'm just a very curious newbie.

Any freebios2 CVS snapshot ?
by Mace Gael 25 Aug '03

25 Aug '03

Hello, working on an AMD platform (dual Opteron), I concentrate one's efforts on the HyperTransport link and related chipset (8111, 8131 and 8151). And first of all, because I want to have under control all blocks, I'm starting by-passing any propriatery BIOS. Also, I'm very interested in getting and testing your FreeBios module and why not offering my contribution. However, all things related to my target are located in your freebios2 branch. And because my (...) proxy doesn't give me permission to access to CVS server, is any snapshot gathering the latest version ? Or any other way than to download manually each file ?

linuxbios on arbor emcore i612?
by Hubert Denkmair 22 Aug '03

22 Aug '03

Hello list, i am planning to build my own car mp3 player in the near future. Therefore I'm going to buy a 3.5" Single Board Computer, and OF COURSE linux will be my operating system of choice :-) Since a fast boot process will be important for me, it seems very useful to buy a board supporting linuxbios. Currently I have a rather cheap SBC on my mind, the "EmCORE-i612VL", manufactured by arbor. Datasheet: ftp://ftp.arbor.com.tw/pub/datasheets/miniboards/emcore-i612.pdf Is this board supported by linuxbios? I looked at the status page and did not find information about this board or even the used i815 chipset. Are the boards mentioned on the status page really the only ones with linuxbios support? If so, can you recommand me a cheap SBC with similar features (+5V power supply only, Celeron400 or equivalent CPU, CF Socket)? Thank you in advance, seems to me you're doing great work! Hubert

Eric, There is one hardcode in src/northbridge/amd/amdk8/northbridge.c to change the value of 0xBC to 0x00ffff00, so the link2 to cpu0 is changed back to link0 again. I changed the hard code to "|" instead of direct assignment. But it hung after get the Ethernet mac address. Any idea? Regards YH.

Eric, Mmio should be the problem. S2885 has link 2 to 8131. I have set the lock to mmio base reg to disable the change to base/limit reg. Before that I found that even I set the correct value in auto.c, after the hardwaremain.c is executed the base reg would change back to link0. The result is that it will hang at the ROM access for Etherboot. I will add more printf in tg3.c today.

Ok. So far the consensus is that we should not have seen any new problems with version 5.2.x, as nothing has changed (except your printf :). So either there is a LinuxBIOS bug where memory mapped I/O is not being properly routed, or you have come across a bug in the driver. It has had a moderate amount of testing, and I did my best to preserve the initialization that the Linux driver was doing when I stripped it down. You do have a version of the tg3 I don't have on hand. So I don't currently have a clue where to start looking except to add more printfs to track down which part of the initialization failed. Eric

Eric, Is ethboot 5.2.0 support Broadcom 5703X? (deviceid = 0x16a7). For the S2885's onboard 5703X, it says: EBUSY err.
