Note that using this option lowers the security
provided by tboot because it makes the system
vulnerable to DMA attacks.
- nobounce [Default off]
- Disable bounce buffer for untrusted devices such as
- the Thunderbolt devices. This will treat the untrusted
- devices as the trusted ones, hence might expose security
- risks of DMA attacks.
intel_idle.max_cstate= [KNL,HW,ACPI,X86]
0 disables intel_idle and fall back on acpi_idle.
option description.
memmap=nn[KMG]@ss[KMG]
- [KNL] Force usage of a specific region of memory.
+ [KNL, X86, MIPS, XTENSA] Force usage of a specific region of memory.
Region of memory to be used is from ss to ss+nn.
If @ss[KMG] is omitted, it is equivalent to mem=nn[KMG],
which limits max address to nn[KMG].
