On Broadwell and above, we have to use different MOCS settings to allow
the kernel to take over and disable caching when needed for external
buffers. On Broadwell, this is especially important because the kernel
can't disable eLLC so we have to do it in userspace. We very badly
don't want to do t
On all other platforms, it's safe to use the usual PTE settings for both
internal and external BOs. On Broadwell, however, we can't get the
right caching behavior for scanout without disabling eLLC and we really
don't want to do this on everything.
In order to do this, we add an anv-specific BO f
