Subject: IRQ behaivour has been changed from v4.14 to v4.15-rc1
Date: Thu, 28 Dec 2017 17:17:24 +0000	[thread overview]
Message-ID: <1514481444.7000.451.camel@intel.com> (raw)

Hi!

Experimenting with AtomISP (yes, code is ugly and MSI handling rather
hackish, though...).

So, with v4.14 base:

[   33.639224] atomisp-isp2 0000:00:03.0: Start stream on pad 1 for asd0
[   33.652355] atomisp-isp2 0000:00:03.0: irq:0x20
[   33.662456] atomisp-isp2 0000:00:03.0: irq:0x20
[   33.698064] atomisp-isp2 0000:00:03.0: stream[0] started.

Ctrl+C

[   48.185643] atomisp-isp2 0000:00:03.0: <atomisp_dqbuf: -512
[   48.204641] atomisp-isp2 0000:00:03.0: release device ATOMISP ISP
CAPTURE output
...

and machine still alive.


With v4.15-rc1 base (basically your branch + some my hack patches) the
IR
Q behaviour changed, i.e. I have got:


[   85.167061] spurious APIC interrupt through vector ff on CPU#0,
should never happen.
[   85.199886] atomisp-isp2 0000:00:03.0: stream[0] started.

and Ctrl+C does NOT work. Machine just hangs.

It might be related to this:

Any comments, Thomas?
