 - HIP_API_BLOCKING : Forces hipMemcpyAsync and hipMemsetAsync to be host-synchronous, meaning they will wait for the requested operation to complete before returning to the caller.
 
 These options cause HCC to serialize.  Useful if you have libraries or code which is calling HCC kernels directly rather than using HIP.  
-- HCC_SERIALZIE_KERNELS : 0x1=pre-serialize before each kernel launch, 0x2=post-serialize after each kernel launch., 0x3= pre- and post- serialize.
+- HCC_SERIALIZE_KERNEL : 0x1=pre-serialize before each kernel launch, 0x2=post-serialize after each kernel launch., 0x3= pre- and post- serialize.
 - HCC_SERIALIZE_COPY    : 0x1=pre-serialize before each async copy, 0x2=post-serialize after each async copy., 0x3= pre- and post- serialize.
 
 - HSA_ENABLE_SDMA=0     : Causes host-to-device and device-to-host copies to use compute shader blit kernels rather than the dedicated DMA copy engines.  Compute shader copies have low latency (typically < 5us) and can achieve approximately 80% of the bandwidth of the DMA copy engine.  This flag is useful to isolate issues with the hardware copy engines.
