CONFIG_GART_IOMMU=y |
| 29 |
Support for full DMA access of devices with 32bit memory access only on |
| 30 |
systems with more than 3GB. This is usually needed for USB, sound, many |
| 31 |
IDE/SATA chipsets and some other devices. Provides a driver for the AMD |
| 32 |
Athlon64/Opteron/Turion/Sempron GART based hardware IOMMU and a software |
| 33 |
bounce buffer based IOMMU used on Intel systems and as fallback. |
| 34 |
The code is only active when needed (enough memory and limited device) |
| 35 |
unless CONFIG_IOMMU_DEBUG or iommu=force is specified too. |
| 36 |
|
| 37 |
CONFIG_CALGARY_IOMMU=y |
| 38 |
Support for hardware IOMMUs in IBM's xSeries x366 and x460 systems. |
| 39 |
Needed to run systems with more than 3GB of memory properly with 32-bit |
| 40 |
PCI devices that do not support DAC (Double Address Cycle). Calgary also |
| 41 |
supports bus level isolation, where all DMAs pass through the IOMMU.... |
| 42 |
|
| 43 |
CONFIG_AMD_IOMMU=y |
| 44 |
With this option you can enable support for AMD IOMMU hardware in your |
| 45 |
system. An IOMMU is a hardware component which provides remapping of DMA |
| 46 |
memory accesses from devices. With an AMD IOMMU you can isolate the the |
| 47 |
DMA memory of different devices and protect the system from misbehaving |
| 48 |
device drivers or hardware. You can find out if your system has an AMD |
| 49 |
IOMMU if you look into your BIOS for an option to enable it or if you |
| 50 |
have an IVRS ACPI table. |

По моему, данные опции выглядят довольно так странно на фоне опции |
