Description
"Type-2" device support is made up of a series of new CXL features. Each of
these features warrants some discussion on it's own.
Features such as P2P, Back-Invalidate, Cache-ID configuration are all
modifications to the core required by accelerator devices.
Dan Williams has already opened up the internal memory configuration to outside
device drivers with his type-2 patch series. However, there are sure to be
additional details which need to be ironed out when real devices start to be
released.
I propose a session covering what support is currently upstream, what support
is planned by my own work on type-2 devices (including qemu work), as well as
what future work will be required. Audience participation will be encouraged,
especially when discussing future work.
