Add executable symbol info for the wavefront size #179

Closed jhuber6 closed 7 months ago

jhuber6 commented 7 months ago

Summary: The wavefront size is currently only exposed as an agent level attribute. This is not correctyl, because while the agent has a default wave front size that is usually correct, it can easily be overridden via options like -mwavefrontsize64 on various ISAs. The wavefrontsize attribute is actually more of a calling convention that is consistent within a callgraph. Because the root of each call graph is a kernel in this architecture, we need to be able to query this on a per-kernel basis. This information is already avialable in the kernel descriptor packet, but it wasn't exported.

This patch adds HSA_CODE_SYMBOL_INFO_KERNEL_WAVEFRONT_SIZE as a new option to query on the executable symbol.

Thank you for the patch. It will be included in ROCm-6.1
