s5p_hash_init(9)
π¦ s5p_hash_init(9) β the kernel API manual, bestie edition π¦
okay so real talk, this one's from the Kernel API Manual (section 9, the kernel-internals girlies π ), and it's about the Samsung s5p hardware hash driver. she's short, she's sweet, she's literally just one function. let's get into it β¨
β¨ NAME β¨
s5p_hash_init β initialize the AHASH request context π
(yes that's it. that's the whole vibe. "contex" is what the original says and I'm not gonna gaslight you about it, but just know it means context okay π)
πΈ SYNOPSIS πΈ
int s5p_hash_init (struct ahash_request *req );
so she takes one pointer and she hands you back an int. that's the whole signature, no cap π
π§ ARGUMENTS π§
reqβ the AHASH request π«Ά that's the thing you're handing over so she can get its context all set up and ready.
π DESCRIPTION π
okay so what she does: she initializes the context of the async hash request. that's it. that's the whole function. not me expecting a whole saga and getting one sentence π but honestly? iconic. she knows her lane. main character energy but make it minimal.
fr fr the entire description is "Init async hash request context." β I'm not adding lore that isn't there, bestie π

go read all of those if you want the full s5p hash cinematic universe π iykyk.
also the kernel file she lives in is ./drivers/crypto/s5p-sss.c π β that's her address, that's her home. π‘
and that's the page, bestie!! π«Ά tysm for reading, drink some water, and remember: the source for all this is ./drivers/crypto and the date on the tin is October 2026 β mwah, love u, bye π
