Misc
----
+The Miscellaneous cgroup provides the resource limiting and tracking
+mechanism for the scalar resources which cannot be abstracted like the other
+cgroup resources. Controller is enabled by the CONFIG_CGROUP_MISC config
+option.
+
+A resource can be added to the controller via enum misc_res_type{} in the
+include/linux/misc_cgroup.h file and the corresponding name via misc_res_name[]
+in the kernel/cgroup/misc.c file. Provider of the resource must set its
+capacity prior to using the resource by calling misc_cg_set_capacity().
+
+Once a capacity is set then the resource usage can be updated using charge and
+uncharge APIs. All of the APIs to interact with misc controller are in
+include/linux/misc_cgroup.h.
+
+Misc Interface Files
+~~~~~~~~~~~~~~~~~~~~
+
+Miscellaneous controller provides 3 interface files. If two misc resources (res_a and res_b) are registered then:
+
+ misc.capacity
+ A read-only flat-keyed file shown only in the root cgroup. It shows
+ miscellaneous scalar resources available on the platform along with
+ their quantities::
+
+ $ cat misc.capacity
+ res_a 50
+ res_b 10
+
+ misc.current
+ A read-only flat-keyed file shown in the non-root cgroups. It shows
+ the current usage of the resources in the cgroup and its children.::
+
+ $ cat misc.current
+ res_a 3
+ res_b 0
+
+ misc.max
+ A read-write flat-keyed file shown in the non root cgroups. Allowed
+ maximum usage of the resources in the cgroup and its children.::
+
+ $ cat misc.max
+ res_a max
+ res_b 4
+
+ Limit can be set by::
+
+ # echo res_a 1 > misc.max
+
+ Limit can be set to max by::
+
+ # echo res_a max > misc.max
+
+ Limits can be set higher than the capacity value in the misc.capacity
+ file.
+
+Migration and Ownership
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A miscellaneous scalar resource is charged to the cgroup in which it is used
+first, and stays charged to that cgroup until that resource is freed. Migrating
+a process to a different cgroup does not move the charge to the destination
+cgroup where the process has moved.

+
+ If no filter range matches an MSR index that is getting accessed, KVM will
+ fall back to rejecting access to the MSR. In this mode, all MSRs that should
+ be processed by KVM need to explicitly be marked as allowed in the bitmaps.
+
+This ioctl allows user space to define up to 16 bitmaps of MSR ranges to
+specify whether a certain MSR access should be explicitly filtered for or not.
+
+If this ioctl has never been invoked, MSR accesses are not guarded and the
+default KVM in-kernel emulation behavior is fully preserved.
+
+Calling this ioctl with an empty set of ranges (all nmsrs == 0) disables MSR
+filtering. In that mode, ``KVM_MSR_FILTER_DEFAULT_DENY`` is invalid and causes
+an error.
+
+As soon as the filtering is in place, every MSR access is processed through
+the filtering except for accesses to the x2APIC MSRs (from 0x800 to 0x8ff);
+x2APIC MSRs are always allowed, independent of the ``default_allow`` setting,
+and their behavior depends on the ``X2APIC_ENABLE`` bit of the APIC base
+register.
+
+If a bit is within one of the defined ranges, read and write accesses are
+guarded by the bitmap's value for the MSR index if the kind of access
+is included in the ``struct kvm_msr_filter_range`` flags. If no range
+cover this particular access, the behavior is determined by the flags
+field in the kvm_msr_filter struct: ``KVM_MSR_FILTER_DEFAULT_ALLOW``
+and ``KVM_MSR_FILTER_DEFAULT_DENY``.
+
+Each bitmap range specifies a range of MSRs to potentially allow access on.
+The range goes from MSR index [base .. base+nmsrs]. The flags field
+indicates whether reads, writes or both reads and writes are filtered
+by setting a 1 bit in the bitmap for the corresponding MSR index.
+
+If an MSR access is not permitted through the filtering, it generates a
+#GP inside the guest. When combined with KVM_CAP_X86_USER_SPACE_MSR, that
+allows user space to deflect and potentially handle various MSR accesses
+into user space.
+
+Note, invoking this ioctl with a vCPU is running is inherently racy. However,
+KVM does guarantee that vCPUs will see either the previous filter or the new
+filter, e.g. MSRs with identical settings in both the old and new filter will
+have deterministic behavior.
