Status of QNAP TS-41x/TS-42x support
QNAP TS-41x/TS-42x devices are based on a Marvell Kirkwood System on a Chip. Marvell has done a lot of work to get support for the Kirkwood platform into the mainline kernel. However, some features of the Kirkwood platform are not as well supported in the mainline kernel (which we use in Debian) as in the original Marvell LSP (Linux Support Package) used by QNAP. Please take this into account before deciding whether you want to install Debian, especially if you have specific requirements (e.g. related to performance).
The table below shows how well different components of the QNAP TS-41x/TS-42x are supported by Debian:
| Component | Comment |

| CPU | Supported in the kernel |
| SATA | Supported in the kernel by the sata_mv module |
| Ethernet | Supported in the kernel by the mv643xx module |
| USB | Supported |
| RTC | Supported in the kernel by the rtc-s35390a module |
| LEDs | Supported in qcontrol |
| LCD | Supported in qcontrol |
| Fan | Supported in qcontrol |
| Beeper | Supported in qcontrol |
| XOR engine | Supported |
| Crypto engine | Basic support |
| Wake-on-LAN (WOL) | Supported in qcontrol. |
| Scheduled power | Supported; see instructions |
