Igor,

To help understand the problem with the TeVii S470 CX23885 MSI not
working after module unload and reload, could you provide the output of

	# lspci -d 14f1: -xxxx -vvvv

as root before the cx23885 module loads, after the module loads, and
after the module is removed and reloaded?

please also provide the MSI IRQ number listed in dmesg
(or /var/log/messages) assigned to the card.  Also the IRQ number of the
unhandled IRQ when the module is reloaded.

The linux kernel should be writing the MSI IRQ vector into the PCI
configuration space of the CX23885.  It looks like when you unload and
reload the cx23885 module, it is not changing the vector.

Regards,
Andy

Andy,
Error appears only and if you zap actual channel(interrupts actually calls).
First time module loaded and zapped some channel. At this point there is no errors.
/proc/interrupts shows some irq's for cx23885.
Then rmmod-insmod and szap again. Voilla! No irq vector.
/proc/interrupts shows zero irq calls for cx23885.
In my case Do_irq complains about irq 153, dmesq says cx23885 uses 45.

My first look not catch anything in lspci.
For now I'm using workaround - find register and bit in cx23885 to write to disable MSI registers.
In conjunction with particular card, naturally.

Regards
Igor

Hi Igor,

On the surface what is going on is now obvious to me:

Previous MSI vector used ------+
(145 = 0x91 and is not 0x99 ! )


The CX23885 hardware is sending the old/previous MSI data in the PCIe
MSI message.

The likely reasons I can think of for this to happen are:

1. The CX23885 chip has a bug and send at least one PCIe MSI message
with the old MSI data, when the MSI data payload in the PCIe config
space of the CX23885 has changed.

2. Your kernel is using the PCI Enhanced Configuration Access Method
(Linux calls it MMCONFIG in dmesg) and PCI MMIO Configuration writes to
the CX23885 are getting reordered due to motherboard/chipset design
problem.  Under these conditions, MSI on the CX23885 could be re-enabled
before the MSI Data vector is updated in the CX23885's PCI config space.

(See page 5 of:
http://www.pcisig.com/specifications/pciexpress/PciEx_ECN_MMCONFIG_040217.pdf )


To eliminate #2 being a problem, could you please boot your kernel with
"pci=nommconf" on the kernel command line and see if the MSI data vector
problem goes away?

Regards,
Andy

Thanks.  I'll try to look at this closely later in the week.

Notice the byte at offset 0xac of the PCI config space:
0x91 -> 145
0x99 -> 153

I think it may be something to do with PCI bus errors and AER.  I have to do more research.  In the meantime you can try booting your kernel with commandline options to:

1. Turn off MSI and look for AER messages to be logged
2.  Turn of AER and see if the IRQ problem goes away.
3. Don't let PCI use MMCONFIG and see if the errors go away.

Regards,
Andy
