Allow to run skcipher speed for given algorithm.
Case 600 is modified to cover ENCRYPT and DECRYPT
directions.
Example:
modprobe tcrypt mode=600 alg="qat_aes_xts" klen=32
If succeed, the performance numbers will be printed in dmesg:
testing speed of multibuffer qat_aes_xts (qat_aes_xts) encryption
test 0 (256 bit key, 16 byte blocks): 1 operation in 14596 cycles (16 bytes)
...
test 6 (256 bit key, 4096 byte blocks): 1 operation in 8053 cycles (4096 bytes)

Commit 7dce59819750 ("crypto: dh - implement ffdheXYZ(dh) templates")
implemented the said templates. Add ffdhe2048(dh) test as it is the
fastest one. This is a requirement for the FIPS certification.

RFC4106 wraps AES in GCM mode, and can be used with larger key sizes
than 128/160 bits, just like AES itself. So add these to the tcrypt
recipe so they will be benchmarked as well.

crypto: tcrypt - Fix multibuffer skcipher speed test mem leak2022-11-25T09:39:18+00:00Zhang Yiqunzhangyiqun@phytium.com.cn2022-11-16T09:24:11+00:00urn:sha1:1aa33fc8d4032227253ceb736f47c52b859d9683
In the past, the data for mb-skcipher test has been allocated
twice, that means the first allcated memory area is without
free, which may cause a potential memory leakage. So this
patch is to remove one allocation to fix this error.

crypto: tcrypt - Drop leading newlines from prints2022-11-04T09:33:22+00:00Anirudh Venkataramanananirudh.venkataramanan@intel.com2022-10-26T19:16:16+00:00urn:sha1:3513828cb8f6db714ee48b1559e6253a57ecf1f6
The top level print banners have a leading newline. It's not entirely
clear why this exists, but it makes it harder to parse tcrypt test output
using a script. Drop said newlines.
tcrypt output before this patch:

[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)

The pr_fmt() define includes KBUILD_MODNAME, and so there's no need
for pr_err() to also print it. Drop module name from the print string.

crypto: tcrypt - Use pr_info/pr_err2022-11-04T09:33:22+00:00Anirudh Venkataramanananirudh.venkataramanan@intel.com2022-10-26T19:16:14+00:00urn:sha1:837a99f59043c3505d69761575172da1d09220b5
Currently, there's mixed use of printk() and pr_info()/pr_err(). The latter
prints the module name (because pr_fmt() is defined so) but the former does
not. As a result there's inconsistency in the printed output. For example:
modprobe mode=211:
[...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes)
[...] test 1 (160 bit key, 64 byte blocks): 1 operation in 2336 cycles (64 bytes)
modprobe mode=215:
[...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2173 cycles (16 bytes)
[...] tcrypt: test 1 (160 bit key, 64 byte blocks): 1 operation in 2241 cycles (64 bytes)
Replace all instances of printk() with pr_info()/pr_err() so that the
module name is printed consistently.
