Questions about the name of qemu bin file for different archs

Questions about the name of qemu bin file for different archs

[Ke, Liping]

Hi, Jessica

I found qemu bin file name convention is different for different archs, for example, for x86, it is bzImage-qemuXXX.
For arm, it is zImage-qemuXXX. My question is why it is bzXXX or zXXX, is there any reason of such naming convention?

Or I must did name translate for each kind of arch qemu bin file? 


Thanks& Regards,

What's more, I found sometimes, for example, there's no symbolic links, so the name is very long and strange.

Such as one ppc image: zImage-2.6.34+git0+d1cd5c80ee97e81e130be8c3de3965b770f320d6_0+9ac0daee43dd19d8bea828cf79450c9748ae0daa-r13-qemuppc-20101210020445.bin

Since I need to download the specific file, so a definite naming is needed such as for x86, it is bzImage-qemux86.bin, for arm, it is bzImage-qemuarm.bin,
For powerpc, it is bzImage-qemupowerpc.bin, etc.

Am I right?

The leading part of the image name is dependent
on the type of kernel we are booting.

]> grep KERNEL_IMAGETYPE qemu*
qemuarm.conf:KERNEL_IMAGETYPE = "zImage"
qemumips.conf:KERNEL_IMAGETYPE = "vmlinux"
qemumips-variant.conf:KERNEL_IMAGETYPE = "vmlinux"
qemuppc.conf:KERNEL_IMAGETYPE = "zImage"
qemux86-64.conf:KERNEL_IMAGETYPE = "bzImage"
qemux86.conf:KERNEL_IMAGETYPE = "bzImage"

And those are your differences in the name.

As for why the symlinks may not be created at times, I'm
not sure.

Should be something you can script by checking the
KERNEL_IMAGETYPE.

Hi, Bruce

Lost this mail and finally found it.

Thanks for your detailed explanation.


And so, for easily fetching those qemu images, we need to make sure that
these symbol-link must be created according to the defined naming convention in the build-result-repository.
I will check this problem firstly.

Thanks & Regards,
