Subject: libahci ->irq_handler vs AHCI_HFLAG_MULTI_MSI
Date: Mon, 17 Oct 2016 21:33:31 +0200 [thread overview]
Message-ID: <20161017193331.GA25533@lst.de> (raw)
Hi all,
did anyone test the AHCI per-port MSI or MSI-X mode recently?
Since commit f070d671 ("libahci: Implement the capability to override the
generic ahci interrupt handler." we reject multi-msi mode when a non-zero
->irq_handler is set, but given that ahci_save_initial_config fills out
->irq_handler long before we call ahci_host_activate I can't think of
a case where it might be non-zero at all.
