📦 version 7.3.1, in nixpkgs unstable

💅 sdma_v4_4_2_inst_ctx_switch_enable(9) 💅

okay so welcome to the Kernel API Manual, bestie ✨ this one's a little function page from the ./drivers/gpu/drm/amd/amdgpu corner of the universe — yes, the header's all truncated and dramatic like sdma_v4_4_2_...witch_enable(9), but the full name is right below, don't worry 🫶

🌸 NAME 🌸

sdma_v4_4_2_inst_ctx_switch_enable — it stops the async dma engines context switch. that's literally it. that's the whole vibe. 💀

✨ SYNOPSIS ✨

void sdma_v4_4_2_inst_ctx_switch_enable (struct amdgpu_device *adev ,
bool enable , uint32_t inst_mask );

like, it returns void — nothing comes back, it just does the thing and leaves. main character energy honestly 👑

🎀 ARGUMENTS 🎀

  • adev — an amdgpu_device pointer. yes bestie, it's the device. the whole device. 🖥️
  • enable — a bool that enables/disables the DMA MEs context switch. true = on, false = off, no in-between, no vibes in the middle 🌈
  • inst_mask — a uint32_t mask of dma engine instances to be enabled. it's a mask, so pick your faves 🎭

🦋 DESCRIPTION 🦋

Halt or unhalt the async dma engines context switch. that's it. halt, or unhalt. two options, both iconic. ✨

💜 SEE ALSO 💜

the kernel file lives at ./drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c — go say hi 👋 and then go read literally all of these, no skipping, i will know 😭:

ngl there are no options, no environment variables, no exit statuses, no signals, and zero bugs listed on this page — if you were waiting for drama, this is not that page 🙈 the whole thing is literally just halt/unhalt. periodt. 💅

okay that's the whole page bestie, and before you go — this lil masterpiece came out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's calling itself sdma_v4_4_2_...witch_enable(9) up top because truncation is basically a personality at this point 🎀💖 stay hydrated, go halt something, love u 🫶✨
