Primus-vk(1)

💖 PVKRUN — THE GLOW UP 💖

ok so this is the manual for Primus-vk, a little general-commands-manual moment. bestie, if you've ever wanted your fancy Vulkan apps to do their thing on one GPU while the picture shows up somewhere else entirely — yeah, that's literally the whole vibe here. let's get into it ✨

✨ NAME ✨

pvkrun — run an application with vulkan calculations on a different graphics card

like, you run an app, and the actual vulkan math happens on a different card than the one you'd expect. main character energy fr fr 🫶

🌸 SYNOPSIS 🌸

pvkrun command

that's it. one command, one job, no notes 💅

🦋 DESCRIPTION 🦋

Primus-vk implements a solution to run applications using the Vulkan-API on a dedicated graphics card, while the image is rendered on an integrated graphics card.

ngl that's the whole pitch: the heavy vulkan lifting goes to the dedicated card, but the actual pixels get shown through the integrated one. the way that works?? obsessed 😭✨

💜 VARIABLES 💜

these are the environment variables that tell primus-vk who's who. lowkey the most important part of this whole page, don't skip them 🙈

• PRIMUS_VK_DISPLAYID — device identification for the device to display the image on (the integrated graphics card, e.g. 8086:591d). the identifiers can be obtained with the vulkaninfo command and are named vendorID and deviceID ✨
• PRIMUS_VK_RENDERID — device identification for the device to render the images on (i.e. the dedicated graphics card). identifier syntax is the same as for the variable PRIMUS_VK_DISPLAYID 🎀

so like — PRIMUS_VK_DISPLAYID is the one showing the picture, PRIMUS_VK_RENDERID is the one doing the work. two cards, two roles, iconic duo behavior 💖

🌈 SEE ALSO 🌈

• vulkaninfo(1)
• primusrun(1)

iykyk — vulkaninfo is where you go to grab those IDs, and primusrun(1) is the sibling vibe for the OpenGL girlies 🧚

and that's the whole page, bestie!! this was written back on August 4 2019 under the name Primus-vk(1) — general commands manual, as the footer said. slay, periodt, go render something 💅✨
