Pull RAS updates from Borislav Petkov:
- Add initial support for RAS hardware found on AMD server GPUs (MI200).
Those GPUs and CPUs are connected together through the coherent
fabric and the GPU memory controllers report errors through x86's MCA
so EDAC needs to support them. The amd64_edac driver supports now HBM
(High Bandwidth Memory) and thus such heterogeneous memory controller
systems
- Other small cleanups and improvements

AMD systems have historically provided an "AMD Node ID" that is a unique
identifier for each die in a multi-die package. This was associated with
a unique instance of the AMD Northbridge on a legacy system. And now it
is associated with a unique instance of the AMD Data Fabric on modern
systems. Each instance is referred to as a "Node"; this is an
AMD-specific term not to be confused with NUMA nodes.
The data fabric provides a number of interfaces accessible through a set
of functions in a single PCI device. There is one PCI device per Data
Fabric (AMD Node), and multi-die systems will see multiple such PCI
devices. The AMD Node ID matches a Node's position in the PCI hierarchy.
For example, the Node 0 is accessed using the first PCI device, Node 1
is accessed using the second, and so on. A logical CPU can find its AMD
Node ID using CPUID. Furthermore, the AMD Node ID is used within the
hardware fabric, so it is not purely a logical value.
Heterogeneous AMD systems, with a CPU Data Fabric connected to GPU data
fabrics, follow a similar convention. Each CPU and GPU die has a unique
AMD Node ID value, and each Node ID corresponds to PCI devices in
sequential order.
However, there are two caveats:
1) GPUs are not x86, and they don't have CPUID to read their AMD Node ID
like on CPUs. This means the value is more implicit and based on PCI
enumeration and hardware-specifics.
2) There is a gap in the hardware values for AMD Node IDs. Values 0-7
are for CPUs and values 8-15 are for GPUs.
For example, a system with one CPU die and two GPUs dies will have the
following values:
CPU0 -> AMD Node 0
GPU0 -> AMD Node 8
GPU1 -> AMD Node 9
EDAC is the only subsystem where this has a practical effect. Memory
errors on AMD systems are commonly reported through MCA to a CPU on the
local AMD Node. The error information is passed along to EDAC where the
AMD EDAC modules use the AMD Node ID of reporting logical CPU to access
AMD Node information.
However, memory errors from a GPU die will be reported to the CPU die.
Therefore, the logical CPU's AMD Node ID can't be used since it won't
match the AMD Node ID of the GPU die. The AMD Node ID of the GPU die is
provided as part of the MCA information, and the value will match the
hardware enumeration (e.g. 8-15).
Handle this situation by discovering GPU dies the same way as CPU dies
in the AMD NB code. But do a "node id" fixup in AMD64 EDAC where it's
needed.
The GPU data fabrics provide a register with the base AMD Node ID for
their local "type", i.e. GPU data fabric. This value is the same for all
fabrics of the same type in a system.
Read and cache the base AMD Node ID from one of the GPU devices during
module initialization. Use this to fixup the "node id" when reporting
memory errors at runtime.

AMD Family 19h Model 30h-3Fh systems can be connected to AMD MI200
accelerator/GPU devices such that the CPU and GPU data fabrics are
connected together. In this configuration, the CPU manages error logging
and reporting for MCA banks located on the GPUs. This includes HBM memory
errors reported from Unified Memory Controllers (UMCs) on the GPUs.
The GPU memory errors are handled like CPU memory errors.
AMD CPU UMC support in EDAC can be re-used for GPU UMC support. However,
keeping them separate means drastic changes in one path (e.g. to support
newer products) should have less impact on the other path.
Also, simplify the "gpu_" helper functions where possible. GPU product
configuration, like memory type and channel count, is fixed compared to
CPU products.
GPU UMCs each have four physical connections (phys) connected to eight
channels. There is a single "chip select". This differs from CPUs where
each UMC has one physical connection connected to one channel, and each
channel has up to four "chip selects".
Enumerate each UMC "phy" as an EDAC CSROW, since there is only a single
chip select for each physical connection. This is similar to how a CPU
UMC "phy" is enumerated as an EDAC CHANNEL, since there is only a single
channel for each physical connection.

The MI200 (Aldebaran) series of devices introduced a new SMCA bank type
for Unified Memory Controllers. The MCE subsystem already has support
for this new type. The MCE decoder module will decode the common MCA
error information for the new bank type, but it will not pass the
information to the AMD64 EDAC module for detailed memory error decoding.
Have the MCE decoder module recognize the new bank type as an SMCA UMC
memory error and pass the MCA information to AMD64 EDAC.

edac_debugfs_create_file() returns ERR_PTR by way of the respective
debugfs function it calls, if an error occurs.
The appropriate way to verify for errors is to use IS_ERR(). Do so.

The AMD64 EDAC module version information is not exposed through ABI
like MODULE_VERSION(). Instead it is printed during module init.
Version numbers can be confusing in cases where module updates are
partly backported resulting in a difference between upstream and
backported module versions.
Remove the AMD64 EDAC module version information to avoid user
confusion.

The LLCC EDAC register offsets varies between each SoC. Hardcoding the
register offsets won't work and will often result in crash due to
accessing the wrong locations.
Hence, get the register offsets from the LLCC driver matching the
individual SoCs.

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.

Not all Qcom platforms support IRQ mode for ECC handling. For those
platforms, the current EDAC driver will not be probed due to missing ECC
IRQ in devicetree.
So add support for polling mode so that the EDAC driver can be used on all
Qcom platforms supporting LLCC.
The polling delay of 5000ms is chosen based on Qcom downstream/vendor
driver.

The Qualcomm LLCC/EDAC drivers were using a fixed register stride for
accessing the (Control and Status Registers) CSRs of each LLCC bank.
This stride only works for some SoCs like SDM845 for which driver
support was initially added.
But the later SoCs use different register stride that vary between the
banks with holes in-between. So it is not possible to use a single register
stride for accessing the CSRs of each bank. By doing so could result in a
crash.
For fixing this issue, let's obtain the base address of each LLCC bank from
devicetree and get rid of the fixed stride. This also means, there is no
need to rely on reg-names property and the base addresses can be obtained
using the index.
First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC
supports more than one bank, then those need to be defined in devicetree
for index from 1..N-1.

Since
8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"),
MODULE_LICENSE declarations are used to identify modules. As
a consequence, uses of the macro in non-modules will cause modprobe to
misidentify their containing object file as a module when it is not
(false positives), and modprobe might succeed rather than failing with
a suitable error message.
altera_edac is not a module for a while now, remove the macro call.

A call to platform_get_irq() already prints an error on failure within
its own implementation. So printing another error based on its return
value in the caller is redundant and should be removed. The clean up
also makes if condition block braces unnecessary. Remove that as well.

GPU Nodes will use a different method to determine the chip select
and channel of an error. A function pointer should be used rather than
introduce another branching condition.
Prepare for this by adding get_err_info() to pvt->ops. This function is
only called from the modern code path, so a legacy function is not
defined.
Make sure to call this after MCA_STATUS[SyndV] is checked, since the
csrow value is found in MCA_SYND.

Call them using a function pointer in pvt->ops. The "ECC enabled"
check is done outside of the hardware information gathering done in
hw_info_get(). So a high-level function pointer is needed to separate

ECC symbol size is not needed on UMC systems, so determine_ecc_sym_sz()
is left out of the UMC path. Do not save TOP_MEM* values on modern
controllers because they're not needed there (read: they were used only
for debugging, if anything).

The bulk of system-specific information is gathered at init time with
hw_info_get(). This function calls a number of helper functions, and
many of these helper functions are split between a modern UMC/DF path
and a legacy DCT path.
Split hw_info_get() into legacy and modern versions. This creates two
separate code paths early on, and legacy and modern helper functions can
be called directly in the appropriate code path.
Also, simplify hw_info_put() and share it between legacy and modern
systems. NULL pointer checks are done in pci_dev_put() and kfree(), so
they can be called unconditionally.

Future AMD systems will support heterogeneous "AMD Node" types, e.g.
CPU and GPU types. Therefore, a global family type shared across all
AMD nodes is no longer appropriate.
Move struct low_ops routines and members of struct amd64_family_type
to struct amd64_pvt.
Currently, there are many code branches that split between "modern" and
"legacy" systems. Another code branch will be needed in order to cover
GPU cases. However, rather than introduce another branching case in
multiple functions, the current branching code should be switched to a
set of function pointers. This change makes the code more readable and
simplifies adding support for new families/models.
In order to reuse code, define two sets of function pointers. Use one
for modern systems (Family 17h and later). This will not change between
current CPU families. Use another set of function pointers for legacy
systems (before Family 17h). Use the Family 16h versions as default
for the legacy ops since these are the latest, and adjust the function
pointers as needed for older families.

The same function is used to calculate chip select size for all Zen-based

Use the "dct" and "umc" prefixes for legacy and modern versions
respectively.
Also, move the "dct" version to avoid a forward declaration, and fixup
some checkpatch warnings in the process.

The current DRAM row address mapping arrays skx_{open,close}_row[]
only support ranks with sizes up to 16G. Decoding a rank address
to a DRAM row address for a 32G rank by using either one of the
above arrays by the skx_edac driver, will result in an overflow on
the array.
For a 32G rank, the most significant DRAM row address bit (the
bit17) is mapped from the bit34 of the rank address. Add this new
mapping item to both arrays to fix the overflow issue.

Reportedly, clang cannot do interprocedural analysis:
https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org
and see that those arguments won't be used uninitialized.
So, yeah, the code's fine even without this. Normally, such a "fix"
won't be applied but that warning gets automatically enabled in -Wall
builds and when CONFIG_WERROR is set in allmodconfig builds, the build
fails.
So shut it up with a minimal fix as this code will see more
reorganization very soon.

The early_channel_count() function seems to have been useful in the past
for knowing how many EDAC mci structures to populate. However, this is no
longer needed as the maximum channel count for a system is used instead.
Remove the early_channel_count() helper functions and related code. Use the
size of the channel layer when iterating over channel structures.

PCI Function 0 is used on Family 17h and later only to read the "dhar"
value. This value is printed and provided through a module-specific
debug sysfs file. The value is not used for any Family 17h and later
code, and it does not have any apparent debug value on these systems.
Remove "dhar", Function 0 PCI IDs, and all related code.

The scrub registers on AMD Family 17h and later may be inaccessible to
the OS. Furthermore, hardware designers recommend that the scrubbing
feature is managed by the firmware.
Remove support for the sdram_scrub_rate interface for AMD Family 17h
systems and later by not setting the scrub function pointers. The EDAC MC
core will then not expose the scrub files in sysfs.
