cik_ib_parse(9)
π cik_ib_parse(9) β the "ib_parse" callback for vm, but make it CIK β¨
okay so bestie, welcome to the cik_ib_parse page π this is one of those (9) kernel API manual pages β a section-9 situation, iykyk π
β¨ NAME β¨
cik_ib_parse β the vm ib_parse callback π¦
πΈ SYNOPSIS πΈ
int cik_ib_parse (struct radeon_device *rdev , struct radeon_ib *ib );
like, that's the whole signature, periodt π
π ARGUMENTS π
rdevβ radeon_device pointer π«Ά (yes, the device, the main character)ibβ indirect buffer pointer β (the ib in question, fr fr)
π DESCRIPTION π
okay so the tea β β CIK does its IB checking in hardware, so this function is literally a nop for CIK π no cap. nothing happens. it's giving "I showed up to the function and did absolutely nothing" energy and honestly? iconic. it just exists so the callback slot is filled, and CIK's hw IB checking handles the rest π
not me writing a whole manpage section for a function that does nothing π but bestie, the callback contract is the moment, okay? we respect the bit.
