Inferior calls (invocation of kernel functions from inside the debugger for expression evaluation) are not supported.

Defining a breakpoint at a location before a kernel (i.e. inside the host code) causes the breakpoint to be also defined at the start of the kernel. This is analogous to defining a breakpoint at a comment line or an empty line and the breakpoint being defined for the next source line.

If the current SIMD lane becomes inactive within a thread, the thread might silently switch its current SIMD lane to its first active SIMD lane.

The

next

and

step

commands may take several seconds to complete execution.

The debugger may stop responding if you disable displaced-stepping before the start of a GPU kernel.
