* | Optimized memset() implementation for POWER | Stewart Smith | 2015-06-01 | 1 | -0/+22 |
| | | | | | | | | | | | | This uses the dcbz instruction to clear cacheline at a time rather than byte at a time. This means that even without high levels of optimization, we *dramatically* improve boot performance with SKIBOOT_GCOV=1 and probably ever so slightly speed things up for normal builds. We currently just hard-code 128 as cacheline size as all CPUs that skiboot currently boots on have 128 byte cachelines. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com> | ||||
