Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner: "This provides support for Intel's Cache Allocation Technology, a cache partitioning mechanism.
The interface is odd, but the hardware interface of that CAT stuff is odd as well.
We tried hard to come up with an abstraction, but that only allows rather simple partitioning, but no way of sharing and dealing with the per package nature of this mechanism.
In the end we decided to expose the allocation bitmaps directly so all combinations of the hardware can be utilized.
There are two ways of associating a cache partition:
- Task
A task can be added to a resource group. It uses the cache partition associated to the group.
- CPU
All tasks which are not member of a resource group use the group to which the CPU they are running on is associated with.
That allows for simple CPU based partitioning schemes.
The main expected user sare:
- Virtualization so a VM can only trash only the associated part of the cash w/o disturbing others
- Real-Time systems to seperate RT and general workloads.
- Latency sensitive enterprise workloads
- In theory this also can be used to protect against cache side channel attacks"
[ Intel RDT is "Resource Director Technology". The interface really is rather odd and very specific, which delayed this pull request while I was thinking about it. The pull request itself came in early during the merge window, I just delayed it until things had calmed down and I had more time.
But people tell me they'll use this, and the good news is that it is _so_ specific that it's rather independent of anything else, and no user is going to depend on the interface since it's pretty rare. So if push comes to shove, we can just remove the interface and nothing will break ]

x86/cpuid: Provide get_scattered_cpuid_leaf()
Sparse populated CPUID leafs are collected in a software provided leaf to avoid bloat of the x86_capability array, but there is no way to rebuild the real leafs (e.g. for KVM CPUID enumeration) other than rereading the CPUID leaf from the CPU. While this is possible it is problematic as it does not take software disabled features into account. If a feature is disabled on the host it should not be exposed to a guest either.
Add get_scattered_cpuid_leaf() which rebuilds the leaf from the scattered cpuid table information and the active CPU features.
