Sorry and thanks for that, I haven saw it in above.
I had some problems in the past when I tried to tune compilation process, using both a72 and a53, but not with Quemu..
The Solution I found was , "the common ground", compile for A53..
Then no more problems..
The quemu you are using was compiled by you?
I found some instructions,
https://www.atrixnet.com/compile-qemu-fr...ckinstall/
But they need better tune on configure.ac, they use explicit call, on configure directly..if you tune configure.ac, you could avoid explicit arguments passed to configure.
This is an option, and make some debug, of it.
Probably its duo to A72 being a 3 way superscaler, out of order, with 2 speculative out of order branch's, I think, but I am not sure, about speculation implemented on A72.
I was asking about compiler, because compiler have been receiving a lot of attention because of meltdown and spectre
Compiling it you can have a better, control of whats going on.
