[Xen-devel] A question on vmx loader in xen - how and when rombios is loaded into memory

["Hu Jia Yi" <jyhu@xxxxxxxxx>]

A “main” function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c.

In this main function, rombios, vgabios and vmxassist are copied to specified address,

with following commands

 

memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz);

…

memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot));

….

 

But after searching the whole directory “firmware”,  I don’t know how and when rombios, vgabios and vmxassist have been loaded to the memory from the disk before calling “memcpy”.

 

Could anybody help me on this?

 

Best regards,

Hu Jia Yi
