2023-08-28EDAC: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-08-02EDAC/igen6: Fix the issue of no error eventsQiuxu Zhuo
Current igen6_edac checks for pending errors before the registration of the error handler. However, there is a possibility that the error occurs during the registration process, leading to unhandled pending errors and no future error events. This issue can be reproduced by repeatedly injecting errors during the loading of the igen6_edac. Fix this issue by moving the pending error handler after the registration of the error handler, ensuring that no pending errors are left unhandled.

2023-06-19EDAC/amd64: Cache and use GPU node mapYazen Ghannam
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.

2023-06-05EDAC/amd64: Add support for AMD heterogeneous Family 19h Model 30h-3FhMuralidhara M K
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.

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.

2023-03-24EDAC/amd64: Add get_err_info() to pvt->opsMuralidhara M K
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.

2023-03-24EDAC/amd64: Rework hw_info_{get,put}Yazen Ghannam
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.

2023-03-24EDAC/amd64: Merge struct amd64_family_type into struct amd64_pvtMuralidhara M K
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.
