request_mem_region 因内存重叠而失败

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

/sbin/lspci -d "10de:*" -v -xxx

03:00.0 3D controller: NVIDIA Corporation GK210GL [Tesla K80] (rev a1)

我认为这是在夺走记忆

[    0.193803] pnp 00:00: disabling [mem 0xfed40000-0xfed44fff] because it overlaps 0000:03:00.0 BAR 1 [mem 0x00000000-0x3ffffffff 64bit pref]

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.
[  606.073942] nvidia-nvlink: Unregistered the Nvlink Core, major device number 511
[  606.553951] nvidia-nvlink: Nvlink Core is being initialized, major device number 511
[  606.553958] NVRM: request_mem_region failed for 0M @ 0x0. This can
               NVRM: occur when a driver such as rivatv is loaded and claims

[  606.554683] nvidia: probe of 0000:03:00.0 failed with error -1

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

   16.326014] NVRM: GPU 0000:03:00.0: RmInitAdapter failed! (0x22:0xffff:667)

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。
