warp.config.enable_tiles_in_stack_memory

warp.config.enable_tiles_in_stack_memory: bool | None = None

Use stack memory instead of static memory for tile allocations on the CPU.

Static memory in kernels is not well supported on some architectures (notably AArch64). We work around it by reserving stack memory on kernel entry and pointing a reserved callee-saved register to it (AArch64) or a single static pointer (x86-64).

When set to None (the default), this flag automatically enables stack memory on aarch64 platforms (Linux ARM) and disables it on other architectures. To explicitly enable or disable this behavior regardless of architecture, set this flag to True or False.
