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.
The
apm driver supports PCI and ISA video cards on the following Alliance ProMotion
chipsets
- ProMotion 6420
- ProMotion 6422
- AT24
- AT3D
- AT25
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.
