Subject: [PATCH v2 3/3] EDAC/amd64: Enumerate memory on noncpu nodes
Date: Fri, 6 Aug 2021 13:13:50 +0530	[thread overview]
Message-ID: <20210806074350.114614-4-nchatrad@amd.com> (raw)
In-Reply-To: <20210806074350.114614-1-nchatrad@amd.com>

On newer heterogeneous systems from AMD with GPU nodes interfaced
with HBM2 memory are connected to the CPUs via custom links.

This patch modifies the amd64_edac module to handle the HBM memory
enumeration leveraging the existing edac and the amd64 specific data
structures.

This patch does the following for non-cpu nodes:
1. Define PCI IDs and ops for Aldeberarn GPUs in family_types array.
2. The UMC Phys on GPU nodes are enumerated as csrows and the UMC channels
   connected to HBMs are enumerated as ranks.
3. Define a function to find the UMCv2 channel number
4. Define a function to calculate base address of the UMCv2 registers
5. Add debug information for UMCv2 channel registers.

Changes since v1:
1. Modifed the commit message
2. Change the edac_cap
3. kept sizes of both cpu and noncpu together
4. return success if the !F3 condition true and remove unnecessary validation
5. declared is_noncpu as bool
6. modified the condition from channel/4 to channel>=4
7. Rearranged debug information for noncpu umcch registers
