Top of the day to you, this is in respect of a very beneficial transaction
which you would not want to let go reply for more details,

The SGL can directly operate caller-provided memory with the exception
of stack memory. The DRBG detects whether the caller provided
non-suitable memory and uses the scratchpad only on those circumstances.
This patch increases the speed of the CTR DRBG by 1 to 3 percent
depending on the buffer
Hi Herbert,
Please find CTR DRBG performance improvements with the patches attached.
In the following, there is an example log taken with my LRNG implementation
using the getrandom(2) system call demonstrating the difference.
Without the patch set:
16 bytes| 12.267661 MB/s|
The CTR DRBG requires two SGLs pointing to input/output buffers for the
CTR AES operation. The used SGLs always have only one entry. Thus, the
SGL can be initialized during allocation time, preventing a
re-initialization of the SGLs during each call.
The performance is increased by about 1 to 3
