# Nouveau Kernel Module Parameters
### `perflvl`/`perflvl_wr`
Specify `nouveau.perflvl_wr=7777` in order to be able to switch performance levels at runtime via `/sys/class/drm/cardN/device/performance_level`. You can also specify `nouveau.perflvl=N` to switch to a specific performance level on boot.
### `tv_norm`
Default TV norm. Default is PAL. Valid values: PAL, PAL-M, PAL-N, PAL-Nc, NTSC-M, NTSC-J, hd480i, hd480p, hd576i, hd576p, hd720p, hd1080i.
This only applies to cards that don't have external encoders.
### `tv_disable`
Disable TV-out detection
### `ignore_lid`
Ignore ACPI lid status
### `duallink`
Allow dual-link TMDS (on by default)
### `agpmode`
AGP mode, 0 to disable AGP
### `vram_pushbuf`
Create DMA push buffers in VRAM
### `config`
This provides a way to configure various parts of the driver, it is a comma-separate list of a=b key/value pairs:
* $engine: bool (whether to enable/disable the engine, e.g. PDISP=0)
* `CLIENT`: debuglevel (one of `fatal, error, warn, info, debug, trace, paranoia, spam`)
* $subdev: debuglevel (e.g. PFB=info)
* `DEVICE`: debuglevel
* `NvGrUseFw`: bool (Whether to load FW for PGRAPH on NVC0)
* `NvBios`: string (Specify VBIOS source as one of `OpenFirmware/PRAMIN/PROM/ACPI/PCIROM/PLATFORM`, or a filename passed to request_firmware)
* `NvForcePost`: bool (Whether to force a POST of the device, off by default)
* `NvI2C`: bool (??, off by default)
* `NvMXMDCB`: bool (Sanitize DCB outputs from the BIOS, on by default)
* `NvFanPWM`: bool (Enable use of PWM for the fan, auto-detect by default)
* `NvPCIE`: bool (NV40 family only, whether to use PCI-E GART, on by default)
### `debug`
Passed to the driver core, controls whether nv_debug statements are shown.
### `noaccel`
Disable kernel/abi16 acceleration
### `modeset`
Whether the driver should be enabled. 0 for disabled, 1 for enabled, 2 for headless
