pvr_queue_job_arm(9)
π pvr_queue_job_arm(9) β the Kernel API Manual glow-up π
okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for pvr_queue_job_arm β yes that whole (9) at the end is the section number, it's giving "I live in the kernel docs now" β¨
β¨ NAME β¨
pvr_queue_job_arm β arm a job object. that's it. that's the whole vibe check. π«Ά
πΈ SYNOPSIS πΈ
struct dma_fence * pvr_queue_job_arm (struct pvr_job *job );
literally just hand it a job and it hands you back a fence, no cap π
π¦ ARGUMENTS π¦
jobβ the job to arm. that's the one, the main character of this whole function π
β DESCRIPTION β
okay so what this does is it initializes the fences and returns the drm_sched finished fence, so it can be exposed to the outside world π that's the whole point of arming β you're getting it ready to be seen.
but β and this is the important part, ngl β once this function is called, you should make sure the job is pushed using pvr_queue_job_push, or guarantee that nobody grabbed a reference to the returned fence π₯
and why do we care? because the latter can happen if we do multi-job submission and something failed when creating/initializing a job π in that case, we know the fence didn't leave the driver, so we can thus guarantee nobody will wait on a dead fence object. periodt. π
π bestie please don't skip this part β the "push it or nobody grabbed the fence" rule is the whole safety net, okay? don't leave a fence orphaned and sad π
