A new method of workaround an error with DPORT is to ensure that the APB is read and followed by the DPORT register without interruptions and pauses. This fix places this implementation in the IRAM to exclude errors associated with the cache miss.
Earlier they have to be selected at the compile time through sdkconfig.

This fixes multiple bugs with ring buffers and re-factors the code. The public
API has not changed, however the underlying implementation have various private
functions have been changed. The following behavioral changes have been made
- Size of ring buffers for No-Split/Allow-Split buffers will not be rounded
up to the nearest 32-bit aligned size. This was done to simplify the
implementation
- Item size for No-Split/Allow-Split buffers will also be rounded up to the
nearest 32-bit aligned size.
The following bugs have been fixed
- In copyItemToRingbufAllowSplit(), when copying an item where the aligned
size is smaller than the remaining length, the function does not consider
the case where the true size of the item is less than 4 bytes.
- The copy functions will automatically wrap around the write pointers when
the remaining length of the buffer is not large enough to fit a header, but
does not consider if wrapping around will cause an overlap with the read
pointer. This will make a full buffer be mistaken for an empty buffer
closes#1711
- xRingbufferSend() can get stuck in a infinite loop when the size of the
free memory is larger than the needed_size, but too small to fit in the ring
buffer due to alignment and extra overhead of wrapping around.
closes#1846
- Fixed documentation with ring buffer queue set API
- Adding and removing from queue set does not consider the case where the
read/write semaphores actually hold a value.
The following functions have been deprecated
- xRingbufferIsNextItemWrapped() due to lack of thread safety
- xRingbufferAddToQueueSetWrite() and xRingbufferRemoveFromQueueSetWrite()
as adding the queue sets only work under receive operations.
The following functions have been added
- xRingbufferReceiveSplit() and xRingbufferReceiveSplitFromISR() as a thread
safe way to receive from allow-split buffers
- vRingbufferGetInfo()
Documentation for ring buffers has also been added.
Add function xRingbufferCanRead & xRingbufferCanWrite
to be able use queue sets. Without it is not possible
to check to which ringbuffer returned semaphore belongs.

If the RTC crystal is bad or has no matched capacitance, then you do not need to start such the crystal. It is necessary to determine this case, output an error (about impossibility to start from the oscillator) and start from the internal RC of the chain.
Reduced the default value of the number of bootstrap cycles. Because we can oscillating the oscillator which then stops. (in Kconfig). Changed from 100 to 5.
The number of calibration cycles has been increased. It is the main criterion for estimating the launch of an oscillator. A large increase leads to an increase in the load time, as well as the stability of recognition of this case. (in Kconfig).
Changed from 1024 to 3000.
This fixes errors logged on the console: sdmmc_req:
handle_idle_state_events unhandled: 00000004 00000000
The issue happens if "data done" event occurs before "command done".
State machine code did not check *which* event occurred in
SENDING_CMD state, and went to IDLE or SENDING_DATA state on any
non-error event. In this case, we can't process "data done" event
until command has completed. This change introduces "unhandled event"
mask, which is carried over from one run of process_events to the
other. This allows waiting for the "command done" event to complete,
and then process "data done" event.

CMD53 in byte mode supports transfers of any number of bytes between 1

When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
As of now, when Bluetooth debugs are enabled, all the messages are
mapped to BT_PRINTF which is mapped to ESP_LOGE. Hence, make monitor
shows all logs in red color which might lead to missing the actual
errors
This patch maps the Bluetooth messages to appropriate ESP_LOG* messages
and improves readability.
Also, make the BT trace level be configurable in menuconfig, so that
each layer of bt trace can be enabled/disabled.
Finally, add debug log control for BTC, OSI, BLUFI and clear up
Bluetooth debug logs.
So, with this the method of enabling Bluetooth logs is as follows:
1. make menuconfig -> Component config -> Bluetooth -> Bluedroid Enable

Currently when page is being freed, items are individually moved from
FREEING page to ACTIVE page and erased. If power-off happens during the
process, the remaining entries are moved to ACTIVE page during recovery.
The problem with this approach is there may not be enough space on
ACTIVE page for all items if an item was partially written before
power-off and erased during recovery. This change moves all the items
from FREEING to ACTIVE page and then erased the FREEING page, If
power-off happens during the process, then ACTIVE page is erased and the
process is restarted.

Current code for recovery after power-off do not clean-up partially
erased items for FULL pages. If the erasure was part of modification
operation, this gets luckily cleaned-up because of duplicate detection
logic. For erase-only operation, the problem still exists. This patch
adds the recovery for FULL pages also.
Closes TW<20284>
When erasing a variable length item with an incorrect CRC32, the span
value of the item can not be trusted, so the item will be erased with
span = 1. Subsequent entries represent the data of the variable
length item, and these will be treated as separate items. For each
entry CRC32 is checked, the check most likely fails (because the
entry contains arbitrary data, and not a proper NVS item), and the
entry is erased. Erase function assumed that every item should be
present in cache, but it is not the case for the entries which are
just parts of item’s payload. This change allows for the item to be
not found in the hashlist, if the CRC32 check fails.
Current page selection algorithm selects a page for compaction based on just erased counts
and gives up when it does not find any page with erased count greater than 0. This is
problematic since the current allocation procedure skips the active page if there is not
enough room for the item in that page leaving free chunks on the pages. This change modifies
the algorithm to consider both erased as well as free counts on the candidate pages.

- In SPI mode, the card will respond to the initial SDIO reset (done
using CMD52) with “invalid command” error. Handle this correctly.
- sdmmc_card_init had a hack where GO_IDLE_STATE (CMD0) command was
sent twice. Add explanation why this is done, and don’t expect
correct response from the card on first CMD0.
- improve logs printed at debug level by adding CMD index
- Add SDIO support at protocol layer (probing, data transfer, interrupts)
- Add SDIO interrupts support in SDMMC host
- Add test (communicate with ESP32 in SDIO download mode)
Existing code assumed that response timeout is not followed by CMD_DONE,
which was not true, in fact. Host datasheet states that CMD_DONE is sent
after an RTO.
All the commands which do not have a response must have their flags set
accordingly. Therefore the host will not send RTO interrupt if response
is not expected. It is a bug in the code logic if it happens otherwise.
SDMMC host suffers from an issue that it outputs data near the rising
edge of the card clock, which is the edge used by the card to sample
data. If sampling time constraint is not satisfied, card may read data
after the transition.
The phases of output/input data can, in fact, be adjusted. However this
adjustment happens in the clock generation block outside of the host.
So the maximum phase change which can be created this way is equal to
half of the host clock period. So if the host clock is set to the lowest
possible frequency (for the given card frequency), then the phase offset
(and hence the hold time) will be the highest. This change modifies the
logic used to determine clock dividers accordingly.
sdmmc host: set correct dout phase and print correct frequency
SET_BUS_WIDTH is not a data transfer command. Extensive search in the
host datasheet and SD card spec did not reveal the origin of this hack
or 'feature'. Further testing showed that removing this does not lead to
regressions.

When splitting a memory block, check if the next block is free.
If it is, then just extend it upwards instead of creating a new block.
This fixes a bug where when shrinking existing allocations would result in irreversible free space fragmentation.
When testing on the host, test all the poisoning configurations.
SDSPI driver optimized polling of the response tokens by requesting
two extra bytes on top of the block size (512) and CRC (2), and
checking whether these bytes contained the data response token or
not. In case the token was there, further polling would not need to
happen, thereby reducing latency between two consecutive blocks
transferred. However this caused compatibility issues when these two
extra bytes were sent after reading the final block. When
STOP_TRANSMISSION command was sent, these extra two bytes were
treated as part of the command, causing an invalid command error.
This fixes the logic by only requesting extra two bytes if the block
being read is not the final block. In addition to that, more strict
error checking is implemented for command response tokens.
The files updated according to code review discussions.
In the sleep_modes.c removed immidiate disable of ULP mode and leave just trigger deactivation.

It is not possible to generate 1 MHz REF_TICK from 2 MHz APB clock
(this is a limitation of REF_TICK divider circuit). Since switching
REF_TICK frequency is something we would like to avoid (to maintain
UART output even with DFS), 2 MHz frequency has been marked as
unsupported.
The issue would manifest itself in cases when switching from PM
configuration like {active=160MHz, idle=80MHz} to {active=80MHz,
idle=80Mhz}. After the configuration was changed, PM logic would
think that current frequency was 80MHz and would not do any further
switching. In fact, frequency was still 160MHz.
The old code calculated MAX() of two enum values, but CPU frequency
enum values are not ordered (2MHz goes after 240MHz). This caused
incorrect configuration to be set.
Previous code contained a check for PLL frequency to be 240MHz, while
in fact 240MHz was a CPU frequency; corresponding PLL frequency is
480MHz. Fixed the comparison and replaced integer MHz values with an
enum.

d0e55335 Component/bt: fix reconnect fail in smp
The fast path of CPU frequency switch function, used in DFS, was not
waiting for the frequency switch to complete when switching from XTAL
to PLL. This resulted in incorrect reads from peripherals on APB,
where two consecutive reads could return the same value. For example,
in esp_timer, read of FRC_COUNT_REG would return same value as the
preceding read of FRC_ALARM_REG, causing time to jump by the value of
FRC_ALARM_REG / apb_freq_mhz.
- separate mode stats from lock stats by an extra comment line
- add CPU frequency column to the mode stats
- don’t print a row for light sleep if light sleep is not enabled
s_cpu_freq_by_mode array was statically initialised with 80MHz CPU
frequency in CPU_MAX and APB_MAX modes, but sdkconfig setting for the
CPU frequency could have been different. For the case of 240MHz CPU
frequency, this would cause a frequency switch between 240MHz and
80MHz to happen, even though such switch is not supported in the fast

This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.
Add back a feature that was available in the old heap implementation
in release/v2.1 and earlier: keep track of which task allocates each
block from the heap. The task handle is conditionally added as
another word in the heap poisoning header under this configuration
option CONFIG_HEAP_TASK_TRACKING.
To allow custom monitoring and debugging code to be added, add helper
functions in multi_heap.c and multi_heap_poisoning.c to provide access
to information in the block headers.
Add esp_heap_debug_dump_totals() to monitor heap usage
esp_heap_debug_dump_totals() dumps into a user-provided data structure
a summary of the amound of heap memory in region type that is used by
each task. Optionally it will also dump into another data structure
the metadata about each allocated block for a given list of tasks or
for all tasks (limited by available space).
Address change requests on PR #1498
This set of changes fixes the files in e3b702c to just add the
CONFIG_HEAP_TASK_TRACKING option without adding the new function
heap_caps_get_per_task_info() in case that is the only portion of the
PR that will be accepted. Part of the change is to remove the new .c
and .h files containing that function and to remove the line to
compile it from components/heap/component.mk since it should not have
been included in e3b702c. One or more additional commits to add the
new function will follow.
The other changes here:
- uint32_t get_all_caps() moves to heap_private.h
- replace "void* foo" with "void *foo"
- add braces around single-line "if" blocks
- replace tab characters with spaces
Address change requests on PR #1498, part 2
This set of changes fixes the files in cdf32aa to add the new function
heap_caps_get_per_task_info() with its new name and to add the line to
compile it in components/heap/component.mk. This does not address all
the suggested changes because there are some needing further
discussion.
This commit does not include the suggested change to move the
declaration of the new function into esp_heap_caps.h because the new
function references TaskHandle_t so esp_heap_caps.h would have to
include freertos/FreeRTOS.h and freertos/task.h, but FreeRTOS.h
includes esp_heap_caps.h through two other header files which results
in compilation errors because not all of FreeRTOS.h has been read yet.
Change heap_caps_get_per_task_info() to take struct of params
In addition to moving the large number of function parameters into a
struct as the single parameter, the following changes were made:
- Clear out the totals for any prepopulated tasks so the app code
doesn't have to do it.
- Rather than partitioning the per-task totals into a predetermined
set of heap capabilities, take a list of <caps,mask> pairs to
compare the caps to the heap capabilities as masked. This lets the
caller configure the desired partitioning, or none.
- Allow the totals array pointer or the blocks array pointer to be
NULL to indicate not to collect that part of the information.
- In addition to returning the total space allocated by each task,
return the number of blocks allocated by each task.
- Don't need to return the heap capabilities as part of the details
for each block since the heap region (and therefore its
capabilities) can be determined from the block address.
- Renamed heap_task_info.h to esp_heap_task_info.h to fit the naming
convention, and renamed the structs for totals and block details to
better fit the revised function name.
- Provide full Doxygen commenting for the function and parameter
structs.

When realloc-ing to a smaller buffer size which ends up allocated in a different heap, the heap
structure is corrupted. This can only happen:
* If heap checking is Comprehensive (meaning buffers are never shrunk in place) and the heap the buffer was originally allocated in is full.
* Calling heap_caps_realloc() to deliberately move a buffer to a different capabilities type, and shrink it at the same time.

Bluedroid use a set of timer function pairs such as btu_start_timer/btu_stop_timer, btu_sys_start_timer/btu_sys_stop_timer for use, in a lack of timer release functions. Thus the timers may be exhausted after some event sequence such as repetition of connection/reconnection with different devices. The maximum timer number used in bluedroid is given by ALARM_CBS_NUM which is 30 for now.

When INT WDT fires, panicHandler is invoked. In OCD mode, panicHandler
sets a breakpoint on the PC from the exception frame and returns.
However in case of INT WDT, interrupt flag is still set in TIMERG1
peripheral, which causes INT WDT to trigger again. This causes an
endless stream of "Core 0 panic'ed (Interrupt wdt timeout on CPU1)"
messages. OpenOCD also gets terribly confused at this point.

This was due to the different order in the macro and the struct. The struct has another order of the fields (opcode, unused, cycles) vs (cycles, unused, opcode):
> struct {
> uint32_t cycles : 16; /*!< Number of cycles to sleep */
> uint32_t unused : 12; /*!< Unused */
> uint32_t opcode : 4; /*!< Opcode (OPCODE_DELAY) */
> } delay; /*!< Format of DELAY instruction */
After updating the order in the macro it is possible to compile with the g++ compiler.

This commit backports vTaskDelete() behavior from FreeRTOS v9.0.0 which
allows for the immediate freeing of task memory if the task being deleted
is not currently running and not pinned to the other core. This commit also
fixes a bug in prvCheckTasksWaitingTermination which prevented the
Idle Task from cleaning up all tasks awaiting deletion. Each iteration of the Idle
Task should traverse the xTasksWaitingTermination list and clean up all tasks
not pinned to the other core. The previous implementation would cause
prvCheckTasksWaitingTermination to return when encountering a task
pinned to the other core whilst traversing the xTasksWaitingTermination list.
The test case for vTaskDelete() has been updated to test for the bugfix and
backported deletion behavior.

Timer callback can delete the timer. If CONFIG_ESP_TIMER_PROFILING was
enabled, this caused an access to invalid (freed) memory.
This fix adds a pointer to track the timer while executing the callback.
This is needed so that we can check if callback deletes the timer,
in which case we won't try updating profiling counters for this timer
after the callback is done.

It was observed that if the ring buffer size provided by application
is not a multiple of 4, some checks were failing (as read_ptr and write_ptr
could shoot beyond the ring buffer boundary), thereby causing asserts.
Simply wrapping around the pointers for such cases fixes the issue.
Moreover, because of the logic for maintaining 4-byte boundary,
it was also possible that a wrap-around occurred for some data,
even when the actual size remaining was sufficient for it.
Eg. Buffer available: 34, data size: 34, 4-byte aligned size: 36
Since the logic compares against 36, it writes 34 bytes and does a
wraparound. But since all 34 bytes are already written, there is
nothing to write after wrapping. It is better to just re-set the
write pointer to the dtart of ring buffer in such cases.
Tested send/receive for various arbitrary sizes of data and for
arbitrary sizes of ring buffer.
Alternative Solutions:
1) Allow only sizes which are multiples of 4, and return error otherwise.
Appropriate code and documentation change would be required
2) Allow arbitrary sizes, but internally add upto 3 bytes to make
the total size a multiple of 4

This call is often part of the generic openssl user code to

This lets the user code set the mbedtls hostname using the standard OpenSSL
X509_VERIFY_PARAM_set1_host() API semantics.
The API takes an X509_VERIFY_PARAM pointer. We use the fact that is
a composed member of the SSL struct to derive the SSL pointer.
The X509_VERIFY_PARAM_set1_host() is unusual in that it can accept a
NUL terminated C string as usual, or a nonterminated pointer + length.
This implementation converts the latter to the former if given, before
using it.
This is enough for user code to get the openssl wrapper to make
mbedtls confirm the CN on the peer cert belongs to the hostname used
to reach it, by doing, eg
X509_VERIFY_PARAM_set1_host(SSL_get0_param(myssl), myhostname, 0);
