evergreen_dma_ib_parse(9)

💖 evergreen_dma_ib_parse — parse the DMA IB for VM 💖

okay bestie, so this one is a Kernel API Manual entry, and no cap it's a tiny little function that does a very specific vibe check on your DMA IB before the kernel commits to anything. let's get into it ✨

---

✨ NAME ✨

evergreen_dma_ib_parse — literally just parses the DMA IB for VM 🫶

---

🌸 SYNOPSIS 🌸

int evergreen_dma_ib_parse (struct radeon_device *rdev , struct
radeon_ib *ib );

that's it. that's the whole signature. short and iconic 💅

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. yes bestie, that's the radeon device itself, the whole main character 👑
• ib — a radeon_ib pointer. this is the IB you're handing over to get parsed 🦋

---

🌈 DESCRIPTION 🌈

so what it actually does: it parses the DMA IB coming in from the VM CS ioctl, and it checks for errors while it's at it. that's the gig. (this is the Cayman-SI situation, iykyk 🧚)

and the return situation? 0 for success, and an error on failure. that's the whole contract, fr fr. no weird edge cases listed here, so don't go inventing any 💀

🔥 SEE ALSO 🔥

• Kernel file ./drivers/gpu/drm/radeon/evergreen_cs.c — go read the source bestie, it's right there 💜
• evergreen_cs_packet_parse_vline(9)
• evergreen_cs_handle_reg(9)
• evergreen_is_safe_reg(9)
• evergreen_dma_cs_parse(9)

all of these are the sibling functions in the same little radeon family, so if you liked this one you'll be obsessed with the rest 🌸

ok that's genuinely everything in the page — nothing skipped, nothing added, the facts are untouched, the vibe is just way better now 💅

and that's a wrap, bestie! 🎀 this one came out of ./drivers/gpu/drm/radeon back in October 2026, and the page you're reading is all about evergreen_dma_ib_parse(9). go forth and parse those IBs responsibly ✨🦋💖
