Dear Maintainer,
After hibernation (using the power button on my laptop) my network card
does not detect link. It works fine in 4.9, it does not work in 4.19, it
still does not work in 5.1.0-rc7.
I bisected the kernel and this is the first bad commit:
commit bc976233a872c0f20f018fb1e89264a541584e25

genirq/msi, x86/vector: Prevent reservation mode for non maskable MSI
The new reservation mode for interrupts assigns a dummy vector when the
interrupt is allocated and assigns a real vector when the interrupt is
requested. The reservation mode prevents vector pressure when
devices with
a large amount of queues/interrupts are initialized, but only a minimal
subset of those queues/interrupts is actually used.
This mode has an issue with MSI interrupts which cannot be masked.
If the
driver is not careful or the hardware emits an interrupt before the
device
irq is requestd by the driver then the interrupt ends up on the dummy
vector as a spurious interrupt which can cause malfunction of the
device or
in the worst case a lockup of the machine.
Change the logic for the reservation mode so that the early
activation of
MSI interrupts checks whether:
- the device is a PCI/MSI device
- the reservation mode of the underlying irqdomain is activated
- PCI/MSI masking is globally enabled
- the PCI/MSI device uses either MSI-X, which supports masking, or
MSI with the maskbit supported.
If one of those conditions is false, then clear the reservation mode
flag
in the irq data of the interrupt and invoke
irq_domain_activate_irq() with
the reserve argument cleared. In the x86 vector code, clear the
can_reserve
flag in the vector allocation data so a subsequent free_irq() won't
create
the same situation again. The interrupt stays assigned to a real vector
until pci_disable_msi() is invoked and all allocations are undone.
Fixes: 4900be83602b ("x86/vector/msi: Switch to global reservation
mode")
Thanks,
Octavio.
