APM(4)                 FreeBSD Kernel Interfaces Manual                 APM(4)

NAME
       apm - Alliance ProMotion video driver

SYNOPSIS
       Section "Device"
         Identifier "devname"
         Driver "apm"
         ...
       EndSection

DESCRIPTION
       apm is an XFree86 driver for Alliance ProMotion video cards. The driver
       is accelerated for supported hardware/depth combination. It supports
       framebuffer depths of 8, 15, 16, 24 and 32 bits. For 6420, 6422, AT24,
       AT3D and AT25, all depths are fully accelerated except 24 bpp for which
       only screen to screen copy and rectangle filling is accelerated.

SUPPORTED HARDWARE
       The apm driver supports PCI and ISA video cards on the following
       Alliance ProMotion chipsets

       ProMotion 6420

       ProMotion 6422

       AT24

       AT3D

       AT25

CONFIGURATION DETAILS
       Please refer to XF86Config(5) for general configuration details.  This
       section only covers configuration details specific to this driver.

       The driver auto-detects the chipset type, but the following ChipSet
       names may optionally be specified in the config file "Device" section,
       and will override the auto-detection:

           "6422", "at24", "at3d".

       The AT25 is Chipset "at3d" and the 6420 is 6422.

       The driver will auto-detect the amount of video memory present for all
       chips. The actual amount of video memory can also be specified with a
       VideoRam entry in the config file "Device" section.

       The following driver Options are supported:

       Option "HWCursor" "boolean"
              Enable or disable the hardware cursor.  Default: on.

       Option "SWCursor" "boolean"
              Force the software cursor.  Default: off.

       Option "NoAccel" "boolean"
              Disable or enable acceleration.  Default: acceleration is
              enabled.

       Option "NoLinear" "boolean"
              Disable or enable use of linear frame buffer. Default: on.
              Note: it may or may not work. Tell me if you need it.

       Option "PciRetry" "boolean"
              Enable or disable PCI retries.  Default: off.

       Option "Remap_DPMS_On" "string"

       Option "Remap_DPMS_Standby" "string"

       Option "Remap_DPMS_Suspend" "string"

       Option "Remap_DPMS_Off" "string"
              Remaps the corresponding DPMS events. I've found that my
              Hercules 128/3D swaps Off and Suspend events. You can correct
              that with
                     Option "Remap_DPMS_Suspend" "Off"
                     Option "Remap_DPMS_Off" "Suspend"
              in the Device section of the config file.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default:
              off.
