This commit restores the vanilla behavior for taskSELECT_HIGHEST_PRIORITY_TASK
when configNUM_CORES == 1 && configUSE_PORT_OPTIMISED_TASK_SELECTION == 0. This
results in the SMP selection algorithm (taskSelectHighestPriorityTaskSMP) to
only be run when configNUM_CORES > 1.
This commit adds preprocessing time checks to ensure that
- configNUM_CORES is defined to 1 or 2
- Incompatible configurations are not set depending on configNUM_CORES
By default, disabled the BLE Encrpyption requirement for provisioning characteristic.
With this flag enabled, when remote attempts to read and if the ACL link is not encrypted,
ESP device will return Insufficient Authentication. It is remote device responsibility to go
for link encryption which may result in pairing.
Some devices do not proceed for any pairing and just show failure pop-up. Also, user needs
to remove bonding on remote phone manually and then try again. This is causing bad user experience.
End user can enable it as per their use case.
List down considerations for the following areas:
- Hardware security
- Network security
- Product security
Also added brief explanation about "Security Policy" for ESP-IDF.
Closes IDF-1565
A missing flush in the serial reader implementation for
Linux target was causing input to idf.py monitor to not
be forwarded to the application. This is fixed now.
On xtensa architecture, the call to __assert_func uses a reference to __func__ that can
sometimes be placed in flash. Since the __asert_func can be called from functions in IRAM
the check_callgraph script can report an error when checking for invalid calls from IRAM
to flash sections. However, the __asert_func prevents this scenario at runtime so the
check_callgraph script reports a 'flas positive' situation. For this reasson, all references
to __func__$x found prior to a call to __assert_func are droped in the parsing of the rtl files.
this commits:
- adds build-time test to check that no call to flash regions are done from IRAM functions
- resolves problems related to IRAM function using content in flash memory
- update heap_caps_alloc_failed to use a default function name in DRAM
when necessary instead of creating a function name variable in DRAM for
each call of heap_caps_alloc_failed. This allows to save some extra bytes
in RAM.
This commits adds a internal.md file in the heap directory to clarify the idea behind
which functions is placed in IRAM or in flash.
A section in mem_alloc.rst documentation is added to specify which functions from the
heap component API can be used in interrupt handlers.
This commit aims to place in the IRAM section only the functions that
are relevent for performance instead of placing the entire content of
multi_heap.c, mullti_heap_poisoning.c and tlsf.c in the IRAM.
