Hello Cédric, with your last message you made me think about and make more test.
>The default machine for qemu-system-ppc64 is pseries. yes usually with 2.8 i boot the VM without issue on G5 Quad with the option -M pseries from 2.1 to 2.5 with kvm-pr enabled. i did the tests and with all pseries now on 2.9 i have the same issue. example: qemu-system-ppc64 --enable-kvm -cpu 970fx_v2.0 -m 1024 -M pseries-2.1 qemu-system-ppc64: KVM and IRQ_XICS capability must be present for in-kernel XICS but no issue if i run with -M mac99 before 2.9 was not possible use it on qemu-system-ppc64 It means it will no possible anymore in future release of qemu use open firmware on powermacs any moore? >I admit the message is not very clear, but the host kernel is >using a dev config. Im so sorry, i learn English by my self reading ml and on irc chatting is too difficult where no one speak English around. >> On Qoriq if i pass the -cpu e500 (normal thing) all is working right qemu >> 2.9rc1 >> all boot and so and so. >but you must be changing the machine right ? not on Qoriq because it is book3e and is not so flexible like the G5 Quad who is book3s machine. i can run qemu kvm only with emb hardware on Qoriq >>On G5 the -cpu variable dont fix the issue. >with which machine ? On PowerMac G5 Quad 970MP it have similar hardware configuration of IBM intellistation power 285 > >I can build a new kernel release , usually mine dont have xics enabled > >because G5 >> dont have that feature, if needed i can enable it for testing.** >Yes that would be interesting. I will do ASAP just the time to build it . Thank you really much for your time and patience.
