Usage
I am using a Blackbird Desktop System with an IBM Power9 v2 (= stepping DD2.3) 8-core CPU as testing infrastructure for open source projects (since Jan, 2020).
Instable hardware watchpoints in stepping DD2.2 (erratum #1: DAWR [Data Access Watchpoint Register] feature is disabled on DD2.2) was the main reason for me to wait for DD2.3 to have reliable low-level debugging available.
System setup

|---|---|---|---|
| Mainboard | Raptor | Blackbird Rev. 1.01 | |
| CPU | IBM | 8-Core POWER9v2 with 3U HSF | |

- 186 W with 100 % CPU load (testet with stress --cpu 32 -t 180s)
Temperatures:
- Idle: 45 Degree Celsius
- 100 % CPU load: 72 Degree Celsius
Noise Level:
- Surprisingly quiet during idle and normal use (low CPU usage)
- Fans spinning fast but not too loud during 100 % CPU load (slow RPM increase and decrease, no annoying sudden changes)
