gsi_init(9)

💅 gsi_init(9) 💅

okay so bestie, welcome to the Kernel API Manual — we're looking at gsi_init(9), and it's giving "first-day-of-school but make it kernel subsystem initialization." 💖

✨ NAME ✨

gsi_init — Initialize the GSI subsystem. no cap, that's the whole vibe. 🦋

✨ SYNOPSIS ✨

int gsi_init (struct gsi *gsi , struct platform_device *pdev , enum
ipa_version version , u32 count , const struct ipa_gsi_endpoint_data
*data );

🎀 ARGUMENTS 🎀

• gsi — address of the GSI structure embedded in an IPA structure. yes, it's literally living inside an IPA structure. 🫶
• pdev — the IPA platform device. main character device energy. 👑
• version — IPA hardware version, which implies the GSI version too. iykyk. ⭐
• count — number of entries in the configuration data array. count 'em. 🔥
• data — endpoint and channel configuration data. the whole configuration moment. 🍓

💖 RETURN 💖

0 if successful, or a negative error code. that's it, that's the return value. 😭

💜 DESCRIPTION 💜

early stage initialization of the GSI subsystem, performing tasks that can be done before the GSI hardware is ready to use. so it's like prepping the group chat before everyone's actually online — the GSI hardware isn't ready yet, but these tasks can happen anyway. ✨
