Hi,
I tried to build a current Linux kernel for the "bamboo" board and use it in
QEMU, but QEMU then quickly aborts with:
pci.c:262: pci_bus_change_irq_level: Assertion `irq_num >= 0' failed.
(or with a "DCR write error" if I try to use the cuImage instead).
I googled a little bit and found this discussion:
https://qemu-devel.nongnu.narkive.com/vYHona3u/emulating-powerpc-440ep-with-qemu-system-ppcemb#post2
Seems like this board was used for KVM on the PPC440 only, and has never
been enabled with the TCG emulation?
Well, KVM support on the 440 has been removed years ago already:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b2677b8dd8de0dc1496ede4da09b9dfd59f15cea
So is this "bamboo" board dead code in QEMU now? Or does anybody still have
a kernel binary which could be used for testing it? Note: This board does
not support "-bios", so u-boot or other firmwares are certainly also not an
option here...
Should we mark "bamboo" as deprecated nowadays?
