scx_bpf_dsq_move_set_slice β NAME, but make it cute π
okay so bestie, welcome to the Kernel API Manual page for scx_bpf_dsq_move_set_slice β aka "Override slice when moving between DSQs". that's the whole name line, we're not gonna be weird about it, we're just gonna read the whole thing together. grab a snack π
β¨ SYNOPSIS β¨
__bpf_kfunc void scx_bpf_dsq_move_set_slice (struct bpf_iter_scx_dsq
*it__iter , u64 slice );
like, that's the whole signature. __bpf_kfunc void, two args, we move. no cap π«Ά
π ARGUMENTS π
it__iterβ the DSQ iterator that's currently in progress. it's mid-walk, it's doing its thing, main character energy πsliceβ how long the moved task gets to run for, measured in nsecs. yes, nanoseconds. she's precise π
π¦ DESCRIPTION π¦
so what this does: it overrides the slice of the next task that's gonna get moved out of it__iter by scx_bpf_dsq_move[_vtime]().
lowkey the important bit: if you don't call this function, the previous slice duration is kept. that's it. that's the rule. no sneaky default, no surprise reset β the old slice just carries over, periodt β¨
fr fr, this only sets up the slice for the next move. don't @ me if you expected it to do something wider, it's literally just the next one π
π SEE ALSO π
bestie there are so many of these and i'm not skipping a single one, we respect the cross-reference list in this house π
