RAS plugin loaded rocm-smi which is in conflict with amd-smi library
Main source of grief was the map 'devInfoTypesStrings' that is defined
in both rocm-smi and amd-smi
We assume that rocm-smi would get lazy-loaded by RAS library and
overwrite symbols defined in amd-smi. devInfoTypesStrings in rocm-smi
contains different number of elements, the enums are also different.
RDC relies on amd-smi's enums.
One such enum is kDevGpuMetrics:
rocm-smi: kDevGpuMetrics = 68
amd-smi: kDevGpuMetrics = 75
Example of overlapping map definitions:
$ objdump --dynamic-syms /opt/rocm/lib/libamd_smi.so | grep devInfoTypesStrings
00000000003c4980 g DO .data.rel.ro0000000000000008 Base devInfoTypesStrings
00000000003db830 g DO .bss0000000000000030 Base _ZN3amd3smi6Device19devInfoTypesStringsE
$ objdump --dynamic-syms /opt/rocm/lib/librocm_smi64.so | grep devInfoTypesStrings
00000000003dc590 g DO .bss0000000000000030 Base _ZN3amd3smi6Device19devInfoTypesStringsE
00000000003c9c68 g DO .data.rel.ro0000000000000008 Base devInfoTypesStrings
