Hi Aaron,
You may want to check the QEMU-q35 target as well:
Automatic boot test returned (PASS/FAIL/TOTAL): 2/2/4 Emulation targets: "QEMU x86 q35/ich9" using payload TianoCore : FAIL : https://lava.9esec.io/r/3427 "QEMU x86 q35/ich9" using payload SeaBIOS : FAIL : https://lava.9esec.io/r/3426 "QEMU x86 i440fx/piix4" using payload SeaBIOS : SUCCESS : https://lava.9esec.io/r/3425 "QEMU AArch64" using payload LinuxBoot_u-root_kexec : SUCCESS : https://lava.9esec.io/r/3424
Thanks Keith

Unfortunately it seems a lot of boards are affected by this. A88XM-E and Lenovo G505S (AMD fam15h) also got broken: they rarely succeed at booting - and, when they do, no boot devices are available (virtual floppies too, for some reason) - except coreinfo/tint secondary payloads which became prone to freezing. I attach the A88XM-E logs I've been able to obtain with USB FT232H:
- ok_e6fb1344ed9188e19be4b54bdf1a76680b8c4523.txt - last coreboot
repo's revision where all the stuff works 2) fail_1_3b02006afe8a85477dafa1bd149f1f0dba02afc7.txt - this commit got the boards broken for the first time 3) fail_2_6b95507ec5b087658178a325bdc68570bc48bb20.txt - this is a log for coreboot's master top
For some reason logs for 2) and 3) always stop after "PCI: 00:12.2 EHCI Debug Port hook triggered".
I hope these commits could be reverted before we figure out what's going on with them. Good thing we've noticed it fast enough.
Thanks, Mike. The amd chipset code (all of it from what I can tell) is fundamentally broken and at odds with all of the resource allocation flow. They worked previously because dynamic resources were being assigned using an algorithm that just assumed there weren't collisions, and that was done w/o all the necessary info required for making the proper decisions regarding dynamic resource allocation.
I landed the other chipsets' fixes, but the amd chipset code is going to take a lot more to fix. Would you be willing to test patches as they are crafted? Given the largeness of the problem as well as the gnarly code that is the amd chipset code it's going to take some time so I think we do need to revert the allocator changes until we can do some house keeping.

Hi guys,
31ab7de51a is CB:41368, cherry picked into my local repo.
Turns out I have to back out all four of Furquan's patches (CB:39486~39489) for my board to boot normally again.
Thoughts?
I'll now get a log with everything in at SPEW.

I see 'Setting RAM size to 768 MB' which means I would expect to see a hole in the ranges representing 768MiB.
that would be bad. I don't know what commit '31ab7de51a' is, but it might not contain the CB:41368. Having SPEW logs would be helpful.
Also, what mainboard Kconfig are you selecting for p3bf? src/mainboard/asus/p2b ?

Just go to the parent of the identified patch. As for the other symptoms you are seeing, I'd love to see logs with the patches we identified so we can root cause.
Thanks.

Ya. Those are fixed from the patches that fixed your device, Keith.
