I am looking at how INVLPGA is emulated in target-i386. it calls
gen_helper_invlpga. tracing down where gen_helper_invlpga is, I found
that it calls helper_invlpg which calls tlb_flush_page.
This tlb_flush_page flushes the env->INVLPGA, I think this tlb is the
x86 tlb. also qemu has another tlb which it uses to translate guest
virt to host virt. Am i right ? What are the relationships between
these 2 ?
Thanks
Xin
