FLAGS FOR SUBMIT_JOB IOCTL COMPUTE COMMAND.(9)

💅 Flags for SUBMIT_JOB ioctl compute command

okay so this is a page straight out of the Kernel API Manual — yes, the actual kernel docs, we're literally in the source tree rn 🫶 — and it's all about the little flags you can OR into the compute command of the SUBMIT_JOB ioctl. Three macros, all iconic, all doing exactly one thing each. Let's get into it bestie ✨

🌸 DESCRIPTION

So the compute command's flag field can hold these bad boys. Each one is a c:macro in the docs, so here they are, one by one, no skipping 💖

• DRM_PVR_SUBMIT_JOB_COMPUTE_CMD_PREVENT_ALL_OVERLAP — the vibe check flag 🚧 it says no other jobs allowed to overlap with this compute job. Straight up "do not perceive me, I'm busy." Disallows overlap with this compute, periodt.
• DRM_PVR_SUBMIT_JOB_COMPUTE_CMD_SINGLE_CORE — main character energy on exactly one core 👑 on a multi-core device, this forces it to use a single core. Like when you need the whole room quiet so you can focus. One core. That's it.
• DRM_PVR_SUBMIT_JOB_COMPUTE_CMD_FLAGS_MASK — the collective 💫 this is the logical OR of all the compute cmd flags. The "everyone's invited" mask, iykyk.

ngl these all just get OR'd together into one flag word — that's the whole game. Nothing spooky, just bit flags doing bit flag things 🦋

✨ SEE ALSO

okay this part is LONG and honestly it ate, so buckle up. The kernel file itself is ./include/uapi/drm/pvr_drm.h — start there, and then there is so much PowerVR lore 🎀
