Hi,
Hi,
I'd like to ask about support for newer CPUs in QEMU, like this one:
system type : BCM3556C0 DTV platform
processor : 0
cpu model : Broadcom BMIPS4380 V4.4 FPU V0.1
BogoMIPS : 403.45
wait instruction : yes
microsecond timers : yes
tlb_entries : 32
extra interrupt vector : yes
hardware watchpoint : no
ASEs implemented : mips16
shadow register sets : 1
core : 0
VCED exceptions : not available
VCEI exceptions : not available
processor : 1
cpu model : Broadcom BMIPS4380 V4.4 FPU V0.1
BogoMIPS : 403.45
wait instruction : yes
microsecond timers : yes
tlb_entries : 32
extra interrupt vector : yes
hardware watchpoint : no
ASEs implemented : mips16
shadow register sets : 1
core : 0
VCED exceptions : not available
VCEI exceptions : not available
I've tried all the available -cpu and -M options combinations (in
QEMU from 0.11 to 0.13) but still no luck to even start booting the
Linux kernel compiled for this CPU.
When I boot the other Linux system image prepared for 'malta'
machine and try to run any even static compiled binaries from
machine which uses the not yet supported CPU I get 'Illegal
instruction' message.
'file' command output on such binaries is:
busybox: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV),
statically linked, stripped
While the ones compiled for system in 'malta' QEMU virtual machine is:
busybox-orig-qemu: ELF 32-bit LSB executable, MIPS, MIPS-I version 1
(SYSV), statically linked, stripped
You need to emulate a platform and a CPU matching your kernel. Currently
QEMU doesn't support this Broadcom CPU, nor this platform.
