![request_mem_region 因内存重叠而失败](https://linux22.com/image/1208222/request_mem_region%20%E5%9B%A0%E5%86%85%E5%AD%98%E9%87%8D%E5%8F%A0%E8%80%8C%E5%A4%B1%E8%B4%A5.png)
我知道我运行的 Tesla K80 并非在其首选的环境中,但我见过普通消费者成功使用该产品,因此我也亲自尝试了一下。https://blog.thomasjungblut.com/random/running-tesla-k80/
我跟着这,使用更新一点的 Ubuntu 版本(Ubuntu 22.04.2 LTS)和来自的驱动程序这里,但显卡内存未分配

我认为这是在夺走记忆

该问题的另一个表现是我的 tty2 被这些消息淹没了:
[ 606.073710] NVRM: The NVIDIA probe routine failed for 2 device(s).
[ 606.073711] NVRM: None of the NVIDIA devices were initialized.

因此,安装的唯一其他图形驱动程序(例如 nouveau)没有被列入黑名单,而英特尔 i915 则被列入黑名单,这导致我出现这些错误

由于 Nvidia Tesla K80 没有视频输出,我更喜欢安装集成显卡驱动程序。
