[Qemu-devel] [Bug 1670175] Re: qemu-system-sparc64 with tribblix-sparc-0m16.iso ends with "panic - kernel: no nucleus hblk8 to allocate" |

Looks like tribblix is an OpenSolaris variant from the above output (I
normally tend to test with Milax but it's good to have another reference
around).
I spent a lot of time during the 2.8 cycle fixing up the context switch
code in OpenBIOS which gets OpenSolaris most of the way. AFAICT the 2
main missing items are:
1) Wiring up the ebus interrupts
I have patches for this, but they cause Linux to panic on startup,
presumably because of 2) below.
2) Fix up the /pci nodes, adding 2 PCI bridges to the DT
This will take some thought since OpenBIOS needs to be modified to
handle multiple PCI buses and has know bugs with PCI bridges.
The CPU for sun4u machines will always be at 100% because the USIIi processor
doesn't have a HLT or equivalent instruction that can be used by the guest to
enable QEMU to pause the vCPU whilst idle.
Note that I work on this as time allows, so progress isn't particularly
rapid. Offers of sponsorship to enable me to spend more time on this
would be gratefully received :)
