Constraints

KSAL has requirements on the processor model and EC algorithm configuration.

It has the following constraints:

• KSAL is available only on Huawei Kunpeng 920 processors.
• The EC algorithm supports only the 2+2, 4+2, 6+2, 8+2, 8+3, 12+3, 20+3, and 25+4 ratios.
• The EC algorithm supports 64-byte and 4,096-byte encoding and decoding granularities.
  

  The default permission on the KSAL dynamic library is 755 (-rwxr-xr-x), and that on the header file is 644 (-rw-r--r--). You are advised to assign minimal permissions (for example, 550) to the files after installing KSAL.
