esp32: SEGGER SystemView Tracing Support

Browse Source 
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

// Hot It Works
// ************
// 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.
