|
|
||
| ## Usage | ||
|
|
||
| Provides: | ||
|
|
||
| * `mei_wdt` | ||
| * `mei_txe` | ||
| * `mei_gsc` | ||
| * `mei_pxp` | ||
| * `mei_hdcp` | ||
| * `mei_me` | ||

||
| Modules are automatically loaded. | ||
|
|
||
| ## Verifiying | ||
|
|
||
| You can verify the modules are enabled by reading the `/proc/modules` where it _should_ show the modules are live. | ||
|
|
||
| For example: | ||
|
|
||
| ``` | ||
| ❯ talosctl -n 192.168.227.5 read /proc/modules | ||
| mei_wdt 12288 - - Live 0xffffffffc030b000 | ||
| mei_txe 28672 - - Live 0xffffffffc02d0000 | ||
| mei_gsc 12288 - - Live 0xffffffffc0247000 | ||
| mei_pxp 12288 - - Live 0xffffffffc02d4000 | ||
| mei_hdcp 16384 - - Live 0xffffffffc02bd000 | ||
| mei_me 45056 - - Live 0xffffffffc0267000 | ||
| mei 131072 - - Live 0xffffffffc0286000 | ||
