pmcraid_ioa_reset(9)
π pmcraid_ioa_reset(9) β Kernel API Manual, but make it make sense
okay so bestie, we're deep in the kernel API manual rn, and this page is about pmcraid_ioa_reset β like, the whole IOA reset situation. buckle up π
β¨ NAME β¨
pmcraid_ioa_reset β the implementation of the IOA reset logic. that's it, that's the vibe. she resets. π
πΈ SYNOPSIS πΈ
void pmcraid_ioa_reset (struct pmcraid_cmd *cmd );
π¦ ARGUMENTS π¦
cmdβ pointer to the cmd block that gets used for the entire reset process. one block, the whole ride. she's committed π«Ά
π DESCRIPTION π
so this function right here does most of the steps required for an IOA reset. like, she's the main character of the reset arc, no cap β¨
who even calls her tho? ok so the callers are:
- user threads (
modprobe/insmod/rmmod) - the timer
- the tasklet
- the midlayer's, all synchronized using the host lock π
and here's the cute detail: all the various functions that get called during the reset process share a single command block, and the pointer to that block is also stored in the adapter instance structure. one block to rule them all, iykyk π
Return Value: None. she does the work, she doesn't return the receipts π
