ata_sff_altstatus(9)
π NAME
okay so bestie, welcome to ata_sff_altstatus β she's a kernel function (from the ata_sff_altstatus(9) manual page, hi π) and her whole entire job is: read the device alternate status reg. that's it. that's the post. β¨
β¨ SYNOPSIS
bool ata_sff_altstatus (struct ata_port *ap , u8 *status );
(no cap, the spacing in there is exactly how the original lays it out β we do not touch π )
π ARGUMENTS
apβ the port where the device is chillin'. like, that's her home address πstatusβ a pointer to a status value. she's gonna get written into, bestie π«Ά
π¦ DESCRIPTION
So what she actually does: she reads the ATA alternate status register for the currently-selected device, and returns its value. literally that. reads it, hands it back to you, done β¨
LOCKING: inherited from caller π β meaning she does not do her own locking, she gets it from whoever called her. so like, the vibes are inherited, the responsibility is yours, iykyk π
πΈ RETURN
trueβ if the register exists πfalseβ if not π
that's the whole vibe check, no in-between.
