◆ psb_offset

uint64_t lldb_private::trace_intel_pt::PSBBlock::psb_offset

The memory offset of a PSB packet that is a synchronization point for the decoder.

A decoder normally looks first for a PSB packet and then it starts decoding.

◆ size

uint64_t lldb_private::trace_intel_pt::PSBBlock::size

Size in bytes of this block.

◆ starting_ip

std::optional<lldb::addr_t> lldb_private::trace_intel_pt::PSBBlock::starting_ip

The first ip for this PSB block.

This is std::nullopt if tracing was disabled when the PSB block was emitted. This means that eventually there's be an enablement event that will come with an ip.

Definition at line 36 of file LibiptDecoder.h.

◆ tsc

std::optional<uint64_t> lldb_private::trace_intel_pt::PSBBlock::tsc

The timestamp associated with the PSB packet above.
