// 1. Components Overview
|
|
// ======================
|
|
|
|
// Xtensa has useful feature: TRAX debug module. It allows recording program execution flow during run-time without disturbing CPU commands flow.
|
|
// Exectution flow data are written to configurable Trace RAM block. Besides accessing Trace RAM itself TRAX module also allows to read/write
|
|
// trace memory via its registers by means of JTAG, APB or ERI transactions.
|
|
// ESP32 has two Xtensa cores with separate TRAX modules on them and provides two special memory regions to be used as trace memory.
|
|
// ESP32 allows muxing access to trace memory blocks in such a way that while one block is accessed by CPUs another can be accessed via JTAG by host
|
|
// via reading/writing TRAX registers. Block muxing is configurable at run-time and allows switching trace memory blocks between
|
|
// accessors in round-robin fashion so they can read/write separate memory blocks without disturbing each other.
|
|
// This moduile implements application tracing feature based on above mechanisms. This feature allows to transfer arbitrary user data to
|
|
// host via JTAG with minimal impact on system performance. This module is implied to be used in the following tracing scheme.
|
|
|
|
// ------>------ ----- (host components) -----
|
|
// | | | |
|
|
// --------------- ----------------------- ----------------------- ---------------- ------ --------- -----------------
|
|
// |apptrace user|-->|target tracing module|<--->|TRAX_MEM0 | TRAX_MEM1|---->|TRAX_DATA_REGS|<-->|JTAG|<--->|OpenOCD|-->|trace data file|
|
|
// --------------- ----------------------- ----------------------- ---------------- ------ --------- -----------------
|
|
// | | | |
|
|
// | ------<------ ---------------- |
|
|
// |<------------------------------------------->|TRAX_CTRL_REGS|<---->|
|
|
// ----------------
|
|
|
|
// In general tracing happens in the following way. User aplication requests tracing module to send some data by calling esp_apptrace_buffer_get(),
|
|
// moduile allocates necessary buffer in current input trace block. Then user fills received buffer with data and calls esp_apptrace_buffer_put().
|
|
// When current input trace block is filled with app data it is exposed to host and the second block becomes input one and buffer filling restarts.
|
|
// While target application fills one memory block host reads another block via JTAG.
|
|
// To control buffer switching and for other communication purposes this implementation uses some TRAX registers. It is safe since HW TRAX tracing
|
|
// can not be used along with application tracing feature so these registers are freely readable/writeable via JTAG from host and via ERI from ESP32 cores.
|
|
// So this implementation's target CPU overhead is produced only by calls to allocate/manage buffers and data copying.
|
|
// On host special OpenOCD command must be used to read trace data.
|
|
|
|
// 2.1.1.1 TRAX Registers layout
|
|
// =============================
|
|
|
|
// This module uses two TRAX HW registers to communicate with host SW (OpenOCD).
|
|
// - Control register uses TRAX_DELAYCNT as storage. Only lower 24 bits of TRAX_DELAYCNT are writable. Control register has the following bitfields:
|
|
// | 31..XXXXXX..24 | 23 .(host_connect). 23| 22..(block_id)..15 | 14..(block_len)..0 |
|
|
// 14..0 bits - actual length of user data in trace memory block. Target updates it every time it fills memory block and exposes it to host.
|
|
// Host writes zero to this field when it finishes reading exposed block;
|
|
// 22..15 bits - trace memory block transfer ID. Block counter. It can overflow. Updated by target, host should not modify it. Actually can be 1-2 bits;
|
|
// 23 bit - 'host connected' flag. If zero then host is not connected and tracing module works in post-mortem mode, otherwise in streaming mode;
|
|
// - Status register uses TRAX_TRIGGERPC as storage. If this register is not zero then currentlly CPU is changing TRAX registers and
|
|
// this register holds address of the instruction which application will execute when it finishes with those registers modifications.
|
|
// See 'Targets Connection' setion for details.
|
|
|
|
// 3. Modes of operation
|
|
// =====================
|
|
|
|
// This module supports two modes of operation:
|
|
// - Post-mortem mode. This is the default mode. In this mode application tracing module does not check whether host has read all the data from block
|
|
// exposed to it and switches block in any case. The mode does not need host interaction for operation and so can be useful when only the latest
|
|
// trace data are necessary, e.g. for analyzing crashes. On panic the latest data from current input block are exposed to host and host can read them.
|
|
// There is menuconfig option CONFIG_ESP32_APPTRACE_ONPANIC_HOST_FLUSH_TRAX_THRESH which control the threshold for flushing data on panic.
|
|
// - Streaming mode. Tracing module enters this mode when host connects to targets and sets respective bit in control register. In this mode tracing
|
|
// module waits for specified time until host read all the data from exposed block.
|
|
// On panic tracing module waits (timeout is configured via menuconfig via ESP32_APPTRACE_ONPANIC_HOST_FLUSH_TMO) for the host to read all data
|
|
// from the previously exposed block.
|
|
|
|
// 4. Communication Protocol
|
|
// =========================
|
|
|
|
// 4.1 Trace Memory Blocks
|
|
// ^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
// Communication is controlled via special register. Host periodically polls control register on each core to find out if there are any data avalable.
|
|
// When current input trace memory block is filled tracing module exposes block to host and updates block_len and block_id fields in control register.
|
|
// Host reads new register value and according to it starts reading data from exposed block. Meanwhile target starts filling another trace block.
|
|
// When host finishes reading the block it clears block_len field in control register indicating to target that it is ready to accept the next block.
|
|
|
|
// 4.2 User Data Chunks Level
|
|
// --------------------------
|
|
|
|
// Since trace memory block is shared between user data chunks and data copying is performed on behalf of the API user (in its normal context) in
|
|
// multithreading environment it can happen that task/ISR which copies data is preempted by another high prio task/ISR. So it is possible situation
|
|
// that task/ISR will fail to complete filling its data chunk before the whole trace block is exposed to the host. To handle such conditions tracing
|
|
// module prepends all user data chunks with 4 bytes header which contains allocated buffer size and actual data length within it. OpenOCD command
|
|
// which reads application traces will report error when it will read incompleted user data block.
|
|
|
|
// 4.3 Targets Connection/Disconnection
|
|
// ------------------------------------
|
|
|
|
// When host is going to start tracing in streaming mode it needs to put both ESP32 cores into initial state when 'host connected' bit is set
|
|
// on both cores. To accomplish this host halts both cores and sets this bit in TRAX registers. But target code can be halted in state when it has read control
|
|
// register but has not updated its value. To handle such situations target code indicates to the host that it is updating control register by writing
|
|
// non-zero value to status register. Actually it writes address of the instruction which it will execute when it finishes with
|
|
// the registers update. When target is halted during control register update host sets breakpoint at the address from status register and resumes CPU.
|
|
// After target code finishes with register update it is halted on breakpoint, host detects it and safely sets 'host connected' bit. When both cores
|
|
// are set up they are resumed. Tracing starts without further intrusion into CPUs work.
|
|
// When host is going to stop tracing in streaming mode it needs to disconnect targets. Disconnection process is done using the same algorithm
|
|
// as for connecting, but 'host connected' bits are cleared on ESP32 cores.
|
|
|
|
// 5. Module Access Synchronization
|
|
// ================================
|
|
|
|
// Access to internal module's data is synchronized with custom mutex. Mutex is a wrapper for portMUX_TYPE and uses almost the same sync mechanism as in
|
|
// vPortCPUAcquireMutex/vPortCPUReleaseMutex. The mechanism uses S32C1I Xtensa instruction to implement exclusive access to module's data from tasks and
|
|
// ISRs running on both cores. Also custom mutex allows specifying timeout for locking operation. Locking routine checks underlaying mutex in cycle until
|
|
// it gets its ownership or timeout expires. The differences of application tracing module's mutex implementation from vPortCPUAcquireMutex/vPortCPUReleaseMutex are:
|
|
// - Support for timeouts.
|
|
// - Local IRQs for CPU which owns the mutex are disabled till the call to unlocking routine. This is made to avoid possible task's prio inversion.
|
|
// When low prio task takes mutex and enables local IRQs gets preempted by high prio task which in its turn can try to acquire mutex using infinite timeout.
|
|
// So no local task switch occurs when mutex is locked. But this does not apply to tasks on another CPU.
|
|
// WARNING: Priority inversion can happen when low prio task works on one CPU and medium and high prio tasks work on another.
|
|
// There are some differences how mutex behaves when it is used from task and ISR context when timeout is non-zero:
|
|
// - In task context when mutex can not be locked portYIELD() is called before check for timeout condition to alow othet tasks work on the same CPU.
|
|
// - In ISR context when mutex can not be locked nothing is done before expired time check.
|
|
// WARNING: Care must be taken when selecting timeout values for trace calls from ISRs. Tracing module does not care about watchdogs when waiting on internal locks
|
|
// and when waiting for host to complete previous block reading, so if wating timeout value exceedes watchdog's one it can lead to system reboot.
|
|
|
|
// 6. Timeouts
|
|
// ------------
|
|
|
|
// Timeout mechanism is based on xthal_get_ccount() routine and supports timeout values in micorseconds.
|
|
// There are two situations when task/ISR can be delayed by tracing API call. Timeout mechanism takes into account both conditions:
|
|
// - Trace data are locked by another task/ISR. When wating on trace data lock.
|
|
// - Current TRAX memory input block is full when working in streaming mode (host is connected). When waiting for host to complete previous block reading.
|
|
// When wating for any of above conditions xthal_get_ccount() is called periodically to calculate time elapsed from trace API routine entry. When elapsed
|
|
// time exceeds specified timeout value operation is canceled and ESP_ERR_TIMEOUT code is returned.
|
|
|
|
