[Qemu-ppc] [PATCH 03/27] ppc/xive: export the TIMA memory accessors |
Date: |
Wed, 6 Mar 2019 09:50:08 +0100 |
The PowerNV machine can perform indirect loads and stores on the TIMA
on behalf of another CPU. Give the controller the possibility to call
the TIMA memory accessors with a XiveTCTX of its choice.
