refactor(core): relocate systemview to sys/dbg
[no changelog]
✓ Descriptive subject✓ Names a concrete action or component✓ Uses a recognizable type or scope! No meaningful explanatory body
What changed, and why it matters
This commit is a straightforward code reorganization: it moves the Segger SystemView debugging subsystem from one directory to another inside the Trezor firmware source tree. It does not change any security-sensitive behavior, fix a bug, or alter how the device protects secrets. The feature remains disabled by default and is only useful when a developer attaches a debugger.
Recommended action
No security action required. Treat as a normal refactoring commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change relocates the Segger SystemView/RTT debug sources from embed/sys/systemview/ to embed/sys/dbg/stm32/systemview/ and integrates them into the existing dbg_console backend under a new USE_DBG_CONSOLE_SYSTEM_VIEW guard. The old SYSTEM_VIEW feature flag is removed from the kernel and secure-monitor SConscripts, and the unconditional enable_systemview() call is removed from drivers_init(). The SystemView code is now only compiled when explicitly enabled via the debug-console option. No cryptographic, storage, or trust-boundary logic is modified.

+File : SEGGER_RTT.c
+Purpose : Implementation of SEGGER real-time transfer (RTT) which
+ allows real-time communication on targets which support
+ debugger memory accesses while the CPU is running.
+Revision: $Rev: 29668 $
+
+Additional information:
+ Type "int" is assumed to be 32-bits in size
+ H->T Host to target communication
+ T->H Target to host communication
+
+ RTT channel 0 is always present and reserved for Terminal usage.
+ Name is fixed to "Terminal"
+
+ Effective buffer size: SizeOfBuffer - 1
+
+ WrOff == RdOff: Buffer is empty
+ WrOff == (RdOff - 1): Buffer is full
+ WrOff > RdOff: Free space includes wrap-around
+ WrOff < RdOff: Used space includes wrap-around
+ (WrOff == (SizeOfBuffer - 1)) && (RdOff == 0):
+ Buffer full and wrap-around after next byte
+

+* pBuffer Pointer to character array. Does not need to point to a \0 terminated string.
+* NumBytes Number of bytes to be stored in the SEGGER RTT control block.
+* MUST be > 0!!!
+* This is done for performance reasons, so no initial check has do be done.
+*
+* Return value
+* 1: Data has been copied
+* 0: No space, data has not been copied
+*
+* Notes
+* (1) If there is not enough space in the "Up"-buffer, all data is dropped.
+* (2) For performance reasons this function does not call Init()
+* and may only be called after RTT has been initialized.
+* Either by calling SEGGER_RTT_Init() or calling another RTT API function first.

+Purpose : System visualization API implementation.

+
+Additional information:
+ Packet format:
+ Packets with IDs 0..23 are standard packets with known structure.
+ For efficiency, they do *NOT* contain a length field.
+ <ID><Data><TimeStampDelta>
+
+ Packets with IDs 24..31 are standard packets with extendible
+ structure and contain a length field.
+ <ID><Lenght><Data><TimeStampDelta>
+
+ Packet ID 31 is used for SystemView extended events.
+ <ID><Lenght><ID_EX><Data><TimeStampDelta>
+
+ Packets with IDs >= 32 always contain a length field.
+ <ID><Length><Data><TimeStampDelta>
+
+ Packet IDs:
+ 0.. 31 : Standard packets, known by SystemView.
+ 32..1023 : OS-definable packets, described in a SystemView description file.
+ 1024..2047 : User-definable packets, described in a SystemView description file.
+ 2048..32767: Undefined.
+
+ Data encoding:
+ Basic types (int, short, char, ...):
+ Basic types are encoded little endian with most-significant bit variant
+ encoding.
+ Each encoded byte contains 7 data bits [6:0] and the MSB continuation bit.
+ The continuation bit indicates whether the next byte belongs to the data
+ (bit set) or this is the last byte (bit clear).
+ The most significant bits of data are encoded first, proceeding to the
+ least significant bits in the final byte (little endian).
+
+ Example encoding:
+ Data: 0x1F4 (500)
+ Encoded: 0xF4 (First 7 data bits 74 | Continuation bit)
+ 0x03 (Second 7 data bits 03, no continuation)
+
+ Data: 0xFFFFFFFF
+ Encoded: 0xFF 0xFF 0xFF 0xFF 0x0F
+
+ Data: 0xA2 (162), 0x03 (3), 0x7000
+ Encoded: 0xA2 0x01 0x03 0x80 0xE0 0x01
+
+ Byte arrays and strings:
+ Byte arrays and strings are encoded as <NumBytes> followed by the raw data.
+ NumBytes is encoded as a basic type with a theoretical maximum of 4G.
+
+ Example encoding:
+ Data: "Hello World\0" (0x48 0x65 0x6C 0x6C 0x6F 0x20 0x57 0x6F 0x72 0x6C 0x64 0x00)
+ Encoded: 0x0B 0x48 0x65 0x6C 0x6C 0x6F 0x20 0x57 0x6F 0x72 0x6C 0x64
+
+ Examples packets:
+ 01 F4 03 80 80 10 // Overflow packet. Data is a single U32.
+ This packet means: 500 packets lost, Timestamp is 0x40000
+
+ 02 0F 50 // ISR(15) Enter. Timestamp 80 (0x50)
+
+ 03 20 // ISR Exit. Timestamp 32 (0x20) (Shortest possible packet.)
+
+ Sample code for user defined Packets:
+ #define MY_ID 0x400 // Any value between 0x400 and 0x7FF
+ void SendMyPacket(unsigned Para0, unsigned Para1, const char* s) {
+ U8 aPacket[SEGGER_SYSVIEW_INFO_SIZE + 2 * SEGGER_SYSVIEW_QUANTA_U32 + MAX_STR_LEN + 1];
+ U8* pPayload;
+ //
+ pPayload = SEGGER_SYSVIEW_PPREPARE_PACKET(aPacket); // Prepare the packet for SystemView
+ pPayload = SEGGER_SYSVIEW_EncodeU32(pPayload, Para0); // Add the first parameter to the packet
+ pPayload = SEGGER_SYSVIEW_EncodeU32(pPayload, Para1); // Add the second parameter to the packet
+ pPayload = SEGGER_SYSVIEW_EncodeString(pPayload, s, MAX_STR_LEN); // Add the string to the packet
+ //
+ SEGGER_SYSVIEW_SendPacket(&aPacket[0], pPayload, MY_ID); // Send the packet with EventId = MY_ID
+ }
+
+ #define MY_ID_1 0x401
+ void SendOnePara(unsigned Para0) {
+ SEGGER_SYSVIEW_RecordU32(MY_ID_1, Para0);
