vmw_cmd_res_check(9)

📦 version 7.3.1, in nixpkgs unstable

💖 vmw_cmd_res_check — the kernel-API manual, but make it make sense 🎀

okay so bestie, welcome to the vmw_cmd_res_check(9) page from the Kernel API Manual 💅 this one's a lil kernel-side helper that does exactly one (1) job and honestly? it ate. let's get into it ✨

✨ NAME ✨

vmw_cmd_res_check — check that a resource is present, and if it is, put it on the resource validate list unless it's already there. that's it, that's the whole vibe 🫶

🌸 SYNOPSIS 🌸

int vmw_cmd_res_check (struct vmw_private *dev_priv , struct
       vmw_sw_context *sw_context , enum vmw_res_type res_type , u32 dirty ,
       const struct vmw_user_resource_conv *converter , uint32_t *id_loc ,
       struct vmw_resource **p_res );

🦋 ARGUMENTS 🦋

  • dev_priv — pointer to a device private structure. the main character of the device world, lowkey 👑
  • sw_context — pointer to the software context. yes queen, the software one 💜
  • res_type — resource type. which flavor of resource are we talking about 🍓
  • dirty — whether to change dirty status. do we touch the dirty bit or nah, that's the question 🙈
  • converter — user-space visible type specific information. the little translation layer for the userspace girlies ✨
  • id_loc — pointer to the location in the command buffer currently being parsed, from where the user-space resource id handle is located. like, where in the buffer are we rn 📍
  • p_res — pointer to pointer to the resource validation node. it gets populated on exit, so it's giving "I'll fill you in later" energy 💅

🔥 SEE ALSO 🔥

okay this list is LONG, like genuinely iconic levels of cross-referencing, but every single one matters so here we go, no skips, fr fr:

the kernel file is ./drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c, and it hangs out with:

like I said. iconic. read them all, iykyk 💀

ngl bestie, the whole point is: resource present? cool, onto the validate list it goes — unless it's already chillin' there, in which case we leave it be. no double-dipping in the validate list, periodt 💅

and that's the page!! source/version: ./drivers/gpu/drm/vmwgfx, dated October 2026 🗓️💖 go forth and validate those resources, bestie — you've got this, fr fr 🌈⭐🫶
