Linux kernel 7.3 is set to bring an update for the iconic Voodoo 3 graphics card from 3dfx, which dominated the gaming landscape in the late 1990s. This update won’t revolutionize the card’s functionality but will enhance its booting capabilities on systems that lack the conventional PC firmware process that normally initializes it.
Historically, the tdfxfb framebuffer driver operated under the assumption that the Voodoo card would be initiated by the PC’s firmware—which was typical during its heyday. However, this assumption fails on modern or unconventional platforms where the VGABIOS isn’t executed. In a significant development, Daniel Palmer, the developer behind the patches, encountered issues while using a Voodoo 3 with an Amiga 4000, prompting the need for this patch that allows the card to be initialized directly from Linux, rather than through firmware.
This update allows the Voodoo 3 to transform from a mere PCI device recognized by Linux to an operational display adapter, able to show pixels on screens even when not initialized by firmware. It results in a basic framebuffer device which enables a Linux console display.
While this is a step toward utilizing vintage hardware in contemporary systems, it does not upgrade the Voodoo 3 to act like a modern graphics card. It remains limited to a legacy graphics interface, lacking the advanced graphics capabilities found in current technologies such as 3D functionality or accelerated rendering.
Contrary to the simple framebuffer update, Palmer is concurrently developing a more exciting 3D path for the Voodoo 3. This includes a new userspace library and a small OpenGL implementation designed to enable the card to run software like Quake without relying on established frameworks such as X or Mesa.
In addition to this, Palmer is progressing with a QEMU emulator for the Voodoo 3, allowing performance testing against both real hardware and the emulator to fine-tune discrepancies in behavior. Though promising, the progress on the 3D capabilities is still experimental and reflects a nostalgic resurgence of interest in legacy technologies.
Ultimately, the Linux kernel 7.3 update for the Voodoo 3 marks a significant yet modest improvement that keeps the spirit of retro computing alive. While it doesn’t revive the card as a fully functional modern GPU, it demonstrates a commitment to ensuring that even older technologies can find new life in contemporary computing environments.
