Merge tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

- Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
this_cpu_inc() on strong load-store architectures.

- Introduce new console_list_lock to synchronize a manipulation of the
list of registered consoles and their flags.

This is a first step in removing the big-kernel-lock-like behavior of
console_lock(). This semaphore still serializes console->write()
calbacks against:

- each other. It primary prevents potential races between early
and proper console drivers using the same device.

- suspend()/resume() callbacks and init() operations in some
drivers.

- various other operations in the tty/vt and framebufer
susbsystems. It is likely that console_lock() serializes even
operations that are not directly conflicting with the
console->write() callbacks here. This is the most complicated
big-kernel-lock aspect of the console_lock() that will be hard
to untangle.

- Introduce new console_srcu lock that is used to safely iterate and
access the registered console drivers under SRCU read lock.

This is a prerequisite for introducing atomic console drivers and
console kthreads. It will reduce the complexity of serialization
against normal consoles and console_lock(). Also it should remove the
risk of deadlock during critical situations, like Oops or panic, when
only atomic consoles are registered.

- Check whether the console is registered instead of enabled on many
locations. It was a historical leftover.

- Cleanly force a preferred console in xenfb code instead of a dirty
hack.

- A lot of code and comment clean ups and improvements.

Merge patch series "IOMMUFD Generic interface"

managing IO page tab

Merge patch series "IOMMUFD Generic interface"

Jason Gunthorpe <jgg@nvidia.com> says:

==================
iommufd is the user API to control the IOMMU subsystem as it relates to
managing IO page tables that point at user space memory.

It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO
container) which is the VFIO specific interface for a similar idea.

We see a broad need for extended features, some being highly IOMMU device
specific:
- Binding iommu_domain's to PASID/SSID
- Userspace IO page tables, for ARM, x86 and S390
- Kernel bypassed invalidation of user page tables
- Re-use of the KVM page table in the IOMMU
- Dirty page tracking in the IOMMU
- Runtime Increase/Decrease of IOPTE size
- PRI support with faults resolved in userspace

Many of these HW features exist to support VM use cases - for instance the
combination of PASID, PRI and Userspace IO Page Tables allows an
implementation of DMA Shared Virtual Addressing (vSVA) within a
guest. Dirty tracking enables VM live migration with SRIOV devices and
PASID support allow creating "scalable IOV" devices, among other things.

As these features are fundamental to a VM platform they need to be
uniformly exposed to all the driver families that do DMA into VMs, which
is currently VFIO and VDPA.

The pre-v1 series proposed re-using the VFIO type 1 data structure,
however it was suggested that if we are doing this big update then we
should also come with an improved data structure that solves the
limitations that VFIO type1 has. Notably this addresses:

- Multiple IOAS/'containers' and multiple domains inside a single FD

- Single-pin operation no matter how many domains and containers use
a page

- A fine grained locking scheme supporting user managed concurrency for
multi-threaded map/unmap

- A pre-registration mechanism to optimize vIOMMU use cases by
pre-pinning pages

- Extended ioctl API that can manage these new objects and exposes
domains directly to user space

- domains are sharable between subsystems, eg VFIO and VDPA

The bulk of this code is a new data structure design to track how the
IOVAs are mapped to PFNs.

iommufd intends to be general and consumable by any driver that wants to
DMA to userspace. From a driver perspective it can largely be dropped in
in-place of iommu_attach_device() and provides a uniform full feature set
to all consumers.

As this is a larger project this series is the first step. This series
provides the iommfd "generic interface" which is designed to be suitable
for applications like DPDK and VMM flows that are not optimized to
specific HW scenarios. It is close to being a drop in replacement for the
existing VFIO type 1 and supports existing qemu based VM flows.

Several follow-on series are being prepared:

- Patches integrating with qemu in native mode:
https://github.com/yiliu1765/qemu/commits/qemu-iommufd-6.0-rc2

- A completed integration with VFIO now exists that covers "emulated" mdev
use cases now, and can pass testing with qemu/etc in compatability mode:
https://github.com/jgunthorpe/linux/commits/vfio_iommufd

- A draft providing system iommu dirty tracking on top of iommufd,
including iommu driver implementations:
https://github.com/jpemartins/linux/commits/x86-iommufd

This pairs with patches for providing a similar API to support VFIO-device
tracking to give a complete vfio solution:
https://lore.kernel.org/kvm/20220901093853.60194-1-yishaih@nvidia.com/

- Userspace page tables aka 'nested translation' for ARM and Intel iommu
drivers:
https://github.com/nicolinc/iommufd/commits/iommufd_nesting

- "device centric" vfio series to expose the vfio_device FD directly as a
normal cdev, and provide an extended API allowing dynamically changing
the IOAS binding:
https://github.com/yiliu1765/iommufd/commits/iommufd-v6.0-rc2-nesting-0901

- Drafts for PASID and PRI interfaces are included above as well

Overall enough work is done now to show the merit of the new API design
and at least draft solutions to many of the main problems.

Several people have contributed directly to this work: Eric Auger, Joao
Martins, Kevin Tian, Lu Baolu, Nicolin Chen, Yi L Liu. Many more have
participated in the discussions that lead here, and provided ideas. Thanks
to all!

The v1/v2 iommufd series has been used to guide a large amount of preparatory
work that has now been merged. The general theme is to organize things in
a way that makes injecting iommufd natural:

- VFIO live migration support with mlx5 and hisi_acc drivers.

iommufd: Data structure to provide IOVA to PFN mapping

This is the remainder of the IOAS data structure. Provide an object called
an io_pagetable that is composed of iopt_areas pointing at iopt_pages,
along with a list of iommu_domains that mirror the IOVA to PFN map.

At the top this is a simple interval tree of iopt_areas indicating the map
of IOVA to iopt_pages. An xarray keeps track of a list of domains. Based
on the attached domains there is a minimum alignment for areas (which may
be smaller than PAGE_SIZE), an interval tree of reserved IOVA that can't
be mapped and an IOVA of allowed IOVA that can always be mappable.

The concept of an 'access' refers to something like a VFIO mdev that is
accessing the IOVA and using a 'struct page *' for CPU based access.

Externally an API is provided that matches the requirements of the IOCTL
interface for map/unmap and domain attachment.

The API provides a 'copy' primitive to establish a new IOVA map in a
different IOAS from an existing mapping by re-using the iopt_pages. This
is the basic mechanism to provide single pinning.

This is designed to support a pre-registration flow where userspace would
setup an dummy IOAS with no domains, map in memory and then establish an
access to pin all PFNs into the xarray.

Copy can then be used to create new IOVA mappings in a different IOAS,
with iommu_domains attached. Upon copy the PFNs will be read out of the
xarray and mapped into the iommu_domains, avoiding any pin_user_pages()
overheads.

iommufd: PFN handling for iopt_pages

The top of the data structure provides an IO Address Space (IOAS) that is
similar to a VFIO container. The IOAS allows map/unmap of memory into
ranges of IOVA called iopt_areas. Multiple IOMMU domains (IO page tables)
and in-kernel accesses (like VFIO mdevs) can be attached to the IOAS to
access the PFNs that those IOVA areas cover.

The IO Address Space (IOAS) datastructure is composed of:
- struct io_pagetable holding the IOVA map
- struct iopt_areas representing populated portions of IOVA
- struct iopt_pages representing the storage of PFNs
- struct iommu_domain representing each IO page table in the system IOMMU
- struct iopt_pages_access representing in-kernel accesses of PFNs (ie
VFIO mdevs)
- struct xarray pinned_pfns holding a list of pages pinned by in-kernel
accesses

This patch introduces the lowest part of the datastructure - the movement
of PFNs in a tiered storage scheme:
1) iopt_pages::pinned_pfns xarray
2) Multiple iommu_domains
3) The origin of the PFNs, i.e. the userspace pointer

PFN have to be copied between all combinations of tiers, depending on the
configuration.

The interface is an iterator called a 'pfn_reader' which determines which
tier each PFN is stored and loads it into a list of PFNs held in a struct
pfn_batch.

Each step of the iterator will fill up the pfn_batch, then the caller can
use the pfn_batch to send the PFNs to the required destination. Repeating
this loop will read all the PFNs in an IOVA range.

The pfn_reader and pfn_batch also keep track of the pinned page accounting.

While PFNs are always stored and accessed as full PAGE_SIZE units the
iommu_domain tier can store with a sub-page offset/length to support
IOMMUs with a smaller IOPTE size than PAGE_SIZE.

interval-tree: Add a utility to iterate over spans in an interval tree

The span iterator travels over the indexes of the interval_tree, not the
nodes, and classifies spans of indexes as either 'used' or 'hole'.

'used' spans are fully covered by nodes in the tree and 'hole' spans have
no node intersecting the span.

This is done greedily such that spans are maximally sized and every
iteration step switches between used/hole.

As an example a trivial allocator can be written as:

for (interval_tree_span_iter_first(&span, itree, 0, ULONG_MAX);
!interval_tree_span_iter_done(&span);
interval_tree_span_iter_next(&span))
if (span.is_hole &&
span.last_hole - span.start_hole >= allocation_size - 1)
return span.start_hole;

With all the tricky boundary conditions handled by the library code.

The following iommufd patches have several algorithms for its overlapping
node interval trees that are significantly simplified with this kind of
iteration primitive. As it seems generally useful, put it into lib/.
