cmd_lc_g

lars (lars@undisclosed.example.com) — 2025-06-12T21:24:17+00:00

command g Format: ‘g’ Meaning: Read general registers. Reply: ‘XX…’ Each byte of register data is described by two hex digits. The bytes with the register are transmitted in target byte order. The size of each register and their position within the ‘g’ packet are determined by the target description (see Target Descriptions); in the absence of a target description, this is done using code internal to GDB; typically this is some customary register layout for the architecture in question.…

notifications These are packets that go from the gdb server to gdb. A notification packet has the form ‘% data # checksum’, where data is the content of the notification, and checksum is a checksum of data, computed and formatted as for ordinary GDB packets. A notification’s data never contains ‘$’, ‘%’ or ‘#’ characters. Upon receiving a notification, the recipient sends no ‘+’ or ‘-’ to acknowledge the notification’s receipt or to report its corruption.

cmd_lc_q_memtags

lars (lars@undisclosed.example.com) — 2025-05-31T11:34:31+00:00

command qMemTags Format: ‘qMemTags:start address,length:type’ Meaning: Fetch memory tags of type type from the address range [start address, start address + length). The target is responsible for calculating how many tags will be returned, as this is architecture-specific.

cmd_ucq_memtags

lars (lars@undisclosed.example.com) — 2025-05-31T11:34:12+00:00

command QMemTags Format: ‘QMemTags:start address,length:type:tag bytes’ Meaning: Store memory tags of type type to the address range [start address, start address + length). The target is responsible for interpreting the type, the tag bytes and modifying the memory tag granules accordingly, given this is architecture-specific.

cmd_uc_z

lars (lars@undisclosed.example.com) — 2025-05-31T11:32:36+00:00

command Z Meaning: Insert a type breakpoint or watchpoint starting at address 'address' of kind 'kind'. Implementation notes: A remote target shall return an empty string for an unrecognized breakpoint or watchpoint packet type. A remote target shall support either both or neither of a given ‘Ztype…’ and ‘ztype…’ packet pair. To avoid potential problems with duplicate packets, the operations should be implemented in an idempotent way.

cmd_uc_q_btrace_conf - created

lars (lars@undisclosed.example.com) — 2025-05-31T11:28:57+00:00

command Qbtrace-conf Format: ‘Qbtrace-conf:bts:size=value’ or ‘Qbtrace-conf:pt:size=value’ or ‘Qbtrace-conf:pt:ptwrite=(yes|no)’ or ‘Qbtrace-conf:pt:event-tracing=(yes|no)’ Meaning: (‘Qbtrace-conf:bts:size=value’) Set the requested ring buffer size for new threads that use the btrace recording method in bts format.

lars (lars@undisclosed.example.com) — 2025-05-31T11:23:55+00:00

command Qbtrace Format: ‘Qbtrace:bts’ or ‘Qbtrace:pt’ or ‘Qbtrace:off’ Meaning: bts: Enable branch tracing for the current thread using Branch Trace Store. pt: Enable branch tracing for the current thread using Intel Processor Trace.

cmd_lc_q_attached - created

lars (lars@undisclosed.example.com) — 2025-05-31T11:21:20+00:00

command qAttached Format: ‘qAttached[:pid]’ Meaning: Return an indication of whether the remote server attached to an existing process or created a new process. When the multiprocess protocol extensions are supported, pid is an integer in hexadecimal format identifying the target process. Otherwise, GDB will omit the pid field and the query packet will be simplified as ‘qAttached’.

cmd_lc_q_xfer - created

lars (lars@undisclosed.example.com) — 2025-05-31T11:18:38+00:00

command qXfer Format: ‘qXfer:object:read:annex:offset,length’ or ‘qXfer:object:write:annex:offset:data…’ or ‘qXfer:object:operation:…’ Meaning: (‘qXfer:object:read:annex:offset,length’) Read uninterpreted bytes from the target’s special data area identified by the keyword object. Request length bytes starting at offset bytes into the data. The content and encoding of annex is specific to object; it can supply additional details about what data to access.

cmd_lc_q_threadextrainfo - created

lars (lars@undisclosed.example.com) — 2025-05-31T09:37:07+00:00

command qThreadExtraInfo Format: ‘qThreadExtraInfo,thread-id’ Meaning: Obtain from the target OS a printable string description of thread attributes for the thread thread-id. This string may contain anything that the target OS thinks is interesting for GDB to tell the user about the thread. The string is displayed in GDB’s info threads display. Some examples of possible thread extra info strings are ‘Runnable’, or ‘Blocked on Mutex’. (Note that the qThreadExtraInfo packet’s name is separated …

cmd_lc_q_symbol - created

lars (lars@undisclosed.example.com) — 2025-05-31T09:34:40+00:00

command qSymbol Format: ‘qSymbol::’ or ‘qSymbol:sym_value:sym_name’ Meaning: (qSymbol::) Notify the target that GDB is prepared to serve symbol lookup requests. Accept requests from the target for the values of symbols. (qSymbol:sym_value:sym_name) Set the value of sym_name to sym_value.

cmd_lc_q_supported - created

lars (lars@undisclosed.example.com) — 2025-05-31T09:16:44+00:00

command qSupported Format: ‘qSupported [:gdbfeature [;gdbfeature]… ]’ Meaning: Tell the remote stub about features supported by GDB, and query the stub for features it supports. This packet allows GDB and the remote stub to take advantage of each others’ features. ‘qSupported’ also consolidates multiple feature probes at startup, to improve GDB performance—a single larger packet performs better than multiple smaller probe packets on high-latency links. Some features may enable behavior which m…

cmd_uc_q_startnoackmode - created

lars (lars@undisclosed.example.com) — 2025-05-31T08:35:51+00:00

command QStartNoAckMode Format: ‘QStartNoAckMode’ Meaning: Request that the remote stub disable the normal ‘+’/‘-’ protocol acknowledgments. GDB acknowledges this response, but neither the stub nor GDB shall send or expect further ‘+’/‘-’ acknowledgments in the current connection.
