Add dynamic interrupt allocation mechanism This adds: - Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int. - Shared interrupts. Enables multiple peripheral drivers to use the same interrupt. - Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled. Also: - Modifies driver to be in line with these changes See merge request !254

Maximum TLS message length (in bytes) supported by mbedTLS.
|
|
|
|
16384 is the default and this value is required to comply
|
|
fully with TLS standards.
|
|
|
|
However you can set a lower value in order to save RAM. This
|
|
is safe if the other end of the connection supports Maximum
|
|
Fragment Length Negotiation Extension (max_fragment_length,
|
|
see RFC6066) or you know for certain that it will never send a
|
|
message longer than a certain number of bytes.
|
|
|
|
If the value is set too low, symptoms are a failed TLS
|
|
handshake or a return value of MBEDTLS_ERR_SSL_INVALID_RECORD
|
|
(-0x7200).

Enable mbedTLS debugging functions.
|
|
|
|
If this option is enabled, use the mbedtls_debug_set_threshold()
|
|
and mbedtls_ssl_conf_dbg() functions to obtain debugging output
|
|
from mbedTLS.
|
|
|
|
Note thatm mbedTLS debugging is not related to the ESP logging
|
|
functionality. See the "https_request_main" example for a
|
|
sample function which connects the two together.

Use an interrupt to coordinate MPI operations.

This allows other code to run on the CPU while an MPI operation is pending.

Otherwise the CPU busy-waits.

Enable hardware accelerated SHA1, SHA256, SHA384 & SHA512 in mbedTLS.
|
|
|
|
Due to a hardware limitation, hardware acceleration is only
|
|
guaranteed if SHA digests are calculated one at a time. If more
|
|
than one SHA digest is calculated at the same time, only will
|
|
be calculated fully in hardware and the rest will be calculated

(at least partially calculated) in software.

help
|
|
System has time.h and time(), gmtime() and the clock is correct.
|
|
The time needs to be correct (not necesarily very accurate, but at least
|
|
the date should be correct). This is used to verify the validity period of
|
|
X.509 certificates.
|
|
|
|
It is suggested that you should get the real time by "SNTP".
