The sysctl interface allows you to obtain run-time information about the driver, any installed NVIDIA graphics cards and the AGP status. It also allows you to control low-level configuration options and/or overrides.
The various pieces of information are held in a hierarchy under hw.nvidia and are accessible with the sysctl(8) command.
NVIDIA sysctl Entries
Prints the installed driver revision
These OIDs provide information about NVIDIA device 'n':
| ID | Description |
|---|---|
| model | the device's product name |
| irq | the IRQ claimed by this device |
| vbios | the device's Video BIOS revision |
| type | the bus type of this device |
These OIDs provide information about the AGP capabilities of the installed AGP graphics card and host-bridge respectively. These values are most likely to be correct after system boot and before the X server is started (and the AGP subsystem initialized).
| ID | Description |
|---|---|
| rates | the AGP rates supported by this device |
| fw | if the device supports AGP fast-writes |
| sba | if the device supports AGP side-band-addressing |
| registers | the device's AGP registers, status:command |
Prints AGP status information based on the AGP command registers of the host-bridge and of the AGP card.
| ID | Description |
|---|---|
| status | if AGP is enabled or disabled |
| driver | which driver is being used |
| rate | the programmed AGP rate |
| fw | if fast-writes are enabled or disabled |
| sba | if side-band-addressing is enabled or disabled |
Low-level kernel module configuration options. Changing these is typically not necessary and potentially dangerous. If you do need to change any of these options, you will need to do so before you start the X server.
| ID | Description |
|---|---|
| status | if AGP is enabled or disabled |
| driver | which driver is being used |
| rate | the programmed AGP rate |
| fw | if fast-writes are enabled or disabled |
| sba | if side-band-addressing is enabled or disabled |
