Allocate segmented trace buffer if firmware advertises the capability in IOCfacts. Upon driver load, read the trace buffer size from driver page 1, calculate the required segments for trace buffer, and allocate segmented buffers. Each segment is 4096 bytes in size. While posting driver diagnostic buffer to firmware, advertise that trace buffer is segmented.
