π pm_qos_read_value(9) π
okay so bestie, welcome to the pm_qos_read_value page β it lives in the Kernel API Manual (section 9, kernel-space girlies only π
) and honestly? it's a little one. a tiny little icon. but she's important, so let's give her main character energy anyway β¨
πΈ NAME πΈ
pm_qos_read_value β returns the current effective constraint value. that's it. that's the whole job. she reads, she returns, she leaves. no cap π
π¦ SYNOPSIS π¦
s32 pm_qos_read_value (struct pm_qos_constraints *c );
literally just hand her a pointer and she hands you back an s32. simple as π«Ά
π ARGUMENTS π
cβ list of PM QoS constraint requests. like, the whole roster of requests, and she's gonna look at it and tell you what the effective value is rn. iykyk π

and that's the whole page!! short and sweet, just how we like her ππ
sign-off time π β this one comes from ./kernel/power, dated October 2026. go forth and read those constraint values, queen ππ₯
