vmw_cmd_dx_bind_query(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… vmw_cmd_dx_bind_query β€” the Kernel API Manual, section 9, bestie πŸŽ€

Okay so we're deep in the Kernel API Manual (section 9, the kernel-functions one, iykyk) and today's main character is vmw_cmd_dx_bind_query. She's a little validation function, she's lowkey iconic, and she has one job. Let's get into it ✨


🌸 SYNOPSIS 🌸

So here's how you call her, fr fr:

int vmw_cmd_dx_bind_query (struct vmw_private *dev_priv , struct
vmw_sw_context *sw_context , SVGA3dCmdHeader *header );

Three args, one int back. No cap. πŸ’–


πŸ¦‹ ARGUMENTS πŸ¦‹

  • dev_priv β€” pointer to a device private struct. That's the device's whole vibe in one struct, basically her home base 🏠
  • sw_context β€” the software context used for this command submission. Every submission gets one of these, and this is the one we're working with rn πŸ’…
  • header β€” pointer to the command header in the command stream. The pointer that starts the whole story πŸ”₯

πŸ‘‘ DESCRIPTION πŸ‘‘

Okay so the query bind operation will eventually associate the query ID with its backing MOB. Not our problem today β€” that's future plans, other people's problem, not on this function's plate πŸ™ˆ

What this function does: we take the user mode MOB ID and run it through vmw_translate_mob_ptr to translate it into its kernel mode equivalent. That's it. That's the whole gig. User-space ID in, kernel-space ID out, slay ✨

Like, genuinely β€” the entire job is that one translation. She's a specialist. She doesn't do extra. Periodt πŸ’œ
