💖 voodoo(4) — Voodoo video driver, section 4 kernel interfaces, bestie 💖

okay so we're in the voodoo manual page (section 4, kernel interfaces) and it's all about the Voodoo video driver. buckle up 🦋

✨ NAME ✨

voodoo — Voodoo video driver. that's it, that's the name 💅

✨ SYNOPSIS ✨

like, here's the config shape you're gonna see:

💖 DESCRIPTION 💖

okay so voodoo is an Xorg driver for Voodoo 1 and Voodoo 2 series video adapters. iconic hardware, no cap 🔥

On the Voodoo 1, the driver uses a shadow buffer in system memory because the video adapter has only 3D acceleration. Selected portions of the shadow framebuffer are copied out to the Voodoo board at the right time. Because of this, the speed of the driver is very dependent on the CPU. Processors nowadays are actually rather fast at moving data, so we get very good speed anyway as the shadow framebuffer is in cached RAM. literally teamwork 💖

The Voodoo2 has 16bpp acceleration, and the driver provides accelerated versions of most operations except angled lines and stipples. Accelerated alpha blending with the Render extension is also supported, as is DGA. slay ✨

This driver supports 16bpp modes currently. The video hardware supports image conversion from 24bpp to 16bpp, but the hardware is 16bpp only. iykyk 🎀

The Voodoo 1 series cards can go up to 800x600 resolution, while the Voodoo 2 can reach 1024x768 providing it has at least 2Mb of frame buffer memory. 1024x768 2D mode does not require two cards configured in scan-line interleave mode (SLI). no cap 🔥

Multihead and Xinerama configurations are supported. SLI configurations will be treated as multiple video cards. group chat energy, honestly 👑

Limited support for DPMS screen saving is available. The "standby" and "suspend" modes are just painting the screen black. The "off" mode turns the Voodoo board off and thus works correctly. okay that one actually works, bestie 💅

🚨 This driver does not support a virtual screen size different from the display size. This is a hardware limitation. 3D rendering is also not supported. like, do not come for this driver with those requests, it's not gonna happen 😭

🛠️ CONFIGURATION DETAILS 🛠️

Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver. the rest is general config lore, bestie 🧚

The following driver Options are supported:

  • Option "ShadowFB" "boolean" — enables a shadow buffer in main memory. This turns off acceleration, but for otherwise unaccelerated operations it can improve performance materially. Default: off for voodoo2, on for voodoo1. okay so voodoo1 girlies get it by default 💖
  • Option "NoAccel" "boolean" — disables acceleration if set. Unless debugging, this option should only be set if ShadowFB is enabled. Default: off for voodoo2, on for voodoo1. debugging only, bestie, don't just flip it for fun 🙈

💀 BUGS 💀

The driver interacts badly with the sstfb frame buffer driver as there is insufficient information to restore the chip to its previous state. so like, they do not vibe together, periodt 💀
