pci_ide_set_nr_streams(9)

🎀 NAME 🎀

okay so bestie, this is pci_ide_set_nr_streams(9) from the Kernel API Manual — and its whole main-character job is: sets size of the pool of IDE Stream resources. no cap 💅

✨ SYNOPSIS ✨

void pci_ide_set_nr_streams (struct pci_host_bridge *hb , u16 nr );

🫶 ARGUMENTS 🫶

• hb — host bridge boundary for the stream pool. literally the boundary, bestie.
• nr — number of streams. yes, the count.

💖 DESCRIPTION 💖

Platform PCI init and/or expert test module use only. This is not a casual-driver situation, okay? It limits IDE Stream establishment by setting the number of stream resources available at the host bridge. 🦋

Platform init code must set this before the first pci_ide_stream_alloc call if the platform has less than the default of 256 streams per host-bridge. Like, before. Not after. The vibe check is early. 😭

The "PCI_IDE" symbol namespace is required because this is typically a detail that is settled in early PCI init. I.e. this export is not for endpoint drivers. periodt. 🎀
