Subject: 32-bit fp/simd race
Date: Wed, 17 Jun 2015 19:56:20 -0700 [thread overview]
Message-ID: <55823354.1040207@samsung.com> (raw)
Maybe I've been looking at this code too long, but it
appears that on __kvm_vcpu_return we save/restore
fp/simd registers and then change to hyp role. In
between if we get an interrupt vCPU may be migrated
to another CPU? Or am I missing something?
Thanks,
- Mario
