Daniel Pouzzner a3fb5029f8 clean up trailing whitespace and misplaced CRLFs, add missing final newlines, remove stray UTF8 nonprintables (BOMs) and ASCIIfy stray homoglyphs (spaces and apostrophes), guided by expanded coverage in wolfssl-multi-test check-source-text. | 3 tháng trước cách đây | |

To build either of these, first build wolfSSL with support for use with QNX CAAM. To do this use the configure option --enable-caam=qnx
bash
source ~/qnx700/qnxsdp-env.sh
./configure --host=arm-unknown-nto-qnx7.0.0eabi --enable-caam=qnx
make
Once the wolfSSL library has been built cd to IDE/QNX/CAAM-DRIVER and run "make". This will produce the wolfCrypt resource manager. It should be started on the device with root permissions. Once wolfCrypt is running on the device with root permissions then any user with access to open a connection to /dev/wolfCrypt can make use of the driver.
To build in momentics IDE:
Typically on smaller block sizes (~ less than 7k) operations are slower with CAAM than software implementations. There is a tunable macro WOLFSSL_CAAM_QNX_MEMORY which sets the size of an internal buffer used currently with AES operations for performance. By default it is set to 250k but can be defined to smaller or larger values. If the block size being encrypted/decrypted does not fit within the buffer size then there will be a big performance hit.
