On a SSE4.2 capable system, `crc32c-intel` should be used, not `crc32c-generic`.
|
|
|
|
|
|
|
|
|
|
Check your CPU (see the `.install` script):
|
|
|
|
|
```shell
|
|
|
|
|
lscpu | grep sse4_2
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Can be enabled with:
|
|
|
|
|
```shell
|
|
|
|
|
MODULES=('crc32c-intel')
|
|
|
|
|
```
|
