All,
I have successfully ported coreboot to the relatively modern ASUS KGPE-D16 server board (dual AMD socket G34, 16 DDR3 DIMMs, https://www.asus.com/us/Commercial_Servers_Workstations/KGPED16/)! This port uses native Family 10h initialization (_not_ AGESA or CIMX).
The Libreboot folks will be interested to know that this board can run blob-free and still retain full functionality!
Port specifications: CPU: Dual AMD G34 Magny-Cours (Family 10h) RAM: 16 DDR3 DIMM slots with ECC support (tested with x4 4G DDR3-1333 unbuffered DIMMs)
Peripherals: PCIe slots: all functional PCI slot: functional RS-232: functional PS/2: expected to function, not tested (on SuperIO) ASpeed VGA device: functional (text mode, see below) IEEE1394: functional On-board USB: functional On-board NICs: functional ASUS PIKE SAS controller: functional PCIe ROMs: functional
Power management: DDR3 voltage set: functional ACPI/APIC: functional Suspend/resume: broken
Other: cbmem console: partial support (log truncated) cbmem timestamps: functional nvram: functional BIOS recovery jumper: functional
ASpeed VGA: The ASpeed VGA device initialises in text mode via its (new) coreboot driver, however this initialisation is incomplete, leading to distorted but quite usable VGA output. When Linux boots and engages the graphical framebuffer all distortion disappears.
This port was not trivial. Almost every device used was broken and required debugging/repair, with the notable exception of the SuperIO chip. The AMD DDR3 controller was severely broken to the point where large rewrites were needed in order to bring it in line with the BKDG. Even after the various component drivers were repaired
Due to the labor-intensive nature of the port and the extensive changes throughout the entire source tree, it is not economically feasible to merge this port upstream at this time (I estimate upward of 30 independent patches would be required just to get the board booting!). Raptor Engineering will, however, be continuing to maintain this port internally, and I am currently looking into adding native Family 15h support on top of this internal tree. Additionally, while it was not a priority for the initial port, I will be attempting to enable suspend/resume functionality as I have time.
If there is sufficient interest from the community in adding this board to coreboot I would consider merging the changes in exchange for a one-time contract payment in the vicinity of $35,000 USD. When considering this offer please bear in mind that this is a fully functional blobless board with a wide range of peripherals and expansion options available, and that once these large changes are merged I will continue to enhance coreboot functionality as before (e.g. with the KFSN4-DRE and the T400). I would also be willing to add this board to the test stand as the only fully supported 4-way Opteron board (socket G34 Magny-Cours CPUs contain two separate CPUs in one package, making this 2-socket board a 4-way system from a HyperTransport perspective).
Please let me know if you have any questions!
