Successful Radeon HD 2400 Pro Mode Setting Test

Posted by Hans

A generous donor has provided me with a Diamond Radeon HD 2400 pro PCI card. I am pleased to announce that, with a small amount of coding, the Radeon HD driver can now initialize this card, and open a screen. This card uses the RV610 chipset and is one generation newer than the Radeon x1300 that was originally used as test card. Now that two cards from different generations have successfully been initialized using the code, it should be fairly easy to add support for more. In fact, many R5xx and R6xx cards should work without any changes to the code.

There are, however, a few issues. The ASIC initialization code within this card's AtomBIOS enters an infinite loop. The BIOS code clears a bit in register 0x600, and then continually tests if that bit is set. Bypassing the ASIC initialization allowed initialization and mode-setting to occur. It appears that the BIOS (i.e., UBOOT) performs the necessary ASIC initialization, making that step redundant. However, I would prefer to have the ASIC initialization step in there, just in case. It might be possible for the AtomBIOS parser to detect an infinite loop and abort the operation. This problem does raise the question as to what the windows driver does. Does it rely on the system BIOS in order to perform basic initialization? Is UBOOT initializing the card differently from the BIOS in standard PCs, resulting in the infinite-loop? It is unlikely that I will ever be able to answer these questions. Regardless, the card is usable. The debug log for initializing this card is given below.
