Merge tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull Compute Express Link (CXL) updates from Dan Williams:
"To date Linux has been dependent on platform-firmware to map CXL RAM
regions and handle events / errors from devices. With this update we
can now parse / update the CXL memory layout, and report events /
errors from devices. This is a precursor for the CXL subsystem to
handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
for DDR-attached-DRAM is handled by the EDAC driver where it maps
system physical address events to a field-replaceable-unit (FRU /
endpoint device). In general, CXL has the potential to standardize
what has historically been a pile of memory-controller-specific error
handling logic.

Another change of note is the default policy for handling RAM-backed
device-dax instances. Previously the default access mode was "device",
mmap(2) a device special file to access memory. The new default is
"kmem" where the address range is assigned to the core-mm via
add_memory_driver_managed(). This saves typical users from wondering
why their platform memory is not visible via free(1) and stuck behind
a device-file. At the same time it allows expert users to deploy
policy to, for example, get dedicated access to high performance
memory, or hide low performance memory from general purpose kernel
allocations. This affects not only CXL, but also systems with
high-bandwidth-memory that platform-firmware tags with the
EFI_MEMORY_SP (special purpose) designation.

Summary:

- CXL RAM region enumeration: instantiate 'struct cxl_region' objects
for platform firmware created memory regions

- CXL RAM region provisioning: complement the existing PMEM region
creation support with RAM region support

- "Soft Reservation" policy change: Online (memory hot-add)
soft-reserved memory (EFI_MEMORY_SP) by default, but still allow
for setting aside such memory for dedicated access via device-dax.

- CXL Events and Interrupts: Takeover CXL event handling from
platform-firmware (ACPI calls this CXL Memory Error Reporting) and
export CXL Events via Linux Trace Events.

- Convey CXL _OSC results to drivers: Similar to PCI, let the CXL
subsystem interrogate the result of CXL _OSC negotiation.

- Emulate CXL DVSEC Range Registers as "decoders": Allow for
first-generation devices that pre-date the definition of the CXL
HDM Decoder Capability to translate the CXL DVSEC Range Registers
into 'struct cxl_decoder' objects.

- Set timestamp: Per spec, set the device timestamp in case of
hotplug, or if platform-firwmare failed to set it.

- General fixups: linux-next build issues, non-urgent fixes for
pre-production hardware, unit test fixes, spelling and debug
message improvements"

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

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.

While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.

First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.

In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.

One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.

The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.

As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.

Summary:

- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.

- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers

- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)

- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism

- Add support for CXL Persistent Memory Security commands

- Add support for the "XOR" algorithm for CXL host bridge interleave

- Rework / simplify CXL to NVDIMM interactions

- Miscellaneous cleanups and fixes"
