๐ xe_guc_ct_q...time_jiffies(9)
okay so bestie, welcome to the Kernel API Manual โจ โ yes it's a kernel page, yes it's got a truncated name with a little ... in the middle (iykyk), and yes we're gonna get through it together. this is the page for xe_guc_ct_queue_proc_time_jiffies, and it's short, so hydrate and let's go ๐ซถ
๐ธ NAME ๐ธ
xe_guc_ct_queue_proc_time_jiffies โ returns the maximum time it takes to process a whole, full CT command queue. literally that's the whole job. ๐
โญ SYNOPSIS โญ
long xe_guc_ct_queue_proc_time_jiffies (struct xe_guc_ct *ct);
๐ ARGUMENTS ๐
ctโ thexe_guc_ct. unused at this moment but it's gonna be used in the future, so likeโฆ character development. the parameter is there, it's just not doing anything yet. ๐
๐ฆ DESCRIPTION ๐ฆ
so here's the observation that this whole function is built on: a 4KiB buffer stuffed full of commands takes a little over a second to process. ๐ญ that's the vibe check. and the function uses that fact to calculate the maximum time needed to process a full CT command queue.
like, that's it. that's the lore. she's a calculator and she's thriving. ๐งฎโจ
๐ RETURN ๐
the maximum time to process a full CT queue, measured in jiffies. that's the unit bestie, don't come at her with seconds. โฑ๏ธ๐

ok that's the whole page and no cap, it really was that short. go read the friends list, there's like sixteen of them, they're all iconic in their own way. ๐
sign-off time ๐ this came to you from ./drivers/gpu/drm/xe, dated October 2026, and it lives at xe_guc_ct_q...time_jiffies(9) โ mwah, take care of her, byeee ๐๐
