Subject: [patch V4 09-01/35] PCI/MSI: Decouple MSI[-X] disable from pcim_release()
Date: Wed, 15 Dec 2021 18:16:44 +0100	[thread overview]
Message-ID: <87tuf9rdoj.ffs@tglx> (raw)
In-Reply-To: <20211210221813.740644351@linutronix.de>

The MSI core will introduce runtime allocation of MSI related data. This
data will be devres managed and has to be set up before enabling
PCI/MSI[-X]. This would introduce an ordering issue vs. pcim_release().

The setup order is:

   pcim_enable_device()
	devres_alloc(pcim_release...);
	...
	pci_irq_alloc()
	  msi_setup_device_data()
	     devres_alloc(msi_device_data_release, ...)

and once the device is released these release functions are invoked in the
opposite order:

    msi_device_data_release()
    ...
    pcim_release()
       pci_disable_msi[x]()

which is obviously wrong, because pci_disable_msi[x]() requires the MSI
data to be available to tear down the MSI[-X] interrupts.

Remove the MSI[-X] teardown from pcim_release() and add an explicit action
to be installed on the attempt of enabling PCI/MSI[-X].

This allows the MSI core data allocation to be ordered correctly in a
subsequent step.
