This code used to work, but as part of the toolchain update it looks
like there must have been a compiler change affecting the relative
precedence of '|=' and '-'. Add parentheses to make the order
explicit.
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.

This is a workaround for the inconsistent device naming pattern
implemented in the device driver for Silicon Labs CP2102 USB to UART
Bridge Controller. When there are multiple devices installed on one
computer, the second and subsequent devices are given a numeric suffix
that increments every time one of the devices is plugged in. Thus,
unplugging and reinserting a cable causes the device name to change.
The workaround is to use the device USB location identifier as an
alternative consistent handle for the device, assuming that the cable
is plugged into the same jack each time. This workaround does not
interfere with using the normal device name as the handle for cases
where only one device is used or when the inconsistent naming is not a
problem.
Chapter Flash from Eclipse: Changed "Select Make Targets -> ..." to "Select Build Targets -> ..." to match the Eclipse wording. Same with "Project -> Make Target" replace Make by build to match the Eclipse wording.
tools/gen_esp_err_to_name.py generates
components/esp32/esp_err_to_name.c for lookup of the error codes from
all of the IDF project and easily identify all codes in one place
