我想将受信任的发送/受信任的接收发送到我的硬盘驱动器。我找到了这个页面: ATA Trusted commands in Linux。(感谢 ehemient 和 Dmitry Obukhov)。
目前,我的问题是如何设置 libata allow_tpm = 1。我使用的是 Ubuntu 13.10。我的代码与 Dmitry Obukhov 相同(它非常适用于识别和所有其他命令,但不适用于受信任的命令。)
在看了另一面之后,这些是我所做的:
- In BIOS, set AHCI mode.
在终端:
- sudo dmesg -c:

- systool -a -v -m libata
Module = "libata"
Attributes:
uevent = <store method only>
version = "3.00"
Parameters:
acpi_gtf_filter = "7"
allow_tpm = "0"
ata_probe_timeout = "0"
atapi_an = "0"
atapi_dmadir = "0"
atapi_enabled = "1"
atapi_passthru16 = "1"
dma = "7"
fua = "0"
ignore_hpa = "0"
noacpi = "0"
zpodd_poweroff_delay= "30"
- sudo nano /etc/modprobe.d/local.conf.
Add this line: options libata allow_tpm=1
- sudo nano /boot/grub/menu.lst.
Add this line: combined_mode=libata
- sudo update-initramfs -u&& sudo update-grub2
重新启动后,我systool -a -v -m libata
再次运行,没有任何变化allow_tpm
。我应该怎么做才能改变allow_tpm
?
