Hi Marc,
I did:
https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git/log/?h=irq/hacks
ok, I'll have a look
You still should be able to enable my favorite
CONFIG_DEBUG_TEST_DRIVER_REMOVE=y, while the distro still boot. But
I'll just test if you want.
Ah! Let me try that then. Having been debugging some ugly driver removal
lately, I wish I had known that config option and inflicted it on their
authors...
Just in case - be careful with this one! It kills the boot of many
systems, but D05 should be fine.
[...]
And while the mbigen port that is connected to the SAS controller
doesn't seem to be shared between endpoints, some other ports definitely
are:
# cat /sys/kernel/debug/irq/domains/\\_SB.MBI1
name: \_SB.MBI1
size: 409
mapped: 192
flags: 0x00000003
[...]
I guess that the other 217 lines are connected somewhere.
I think that is not the right one. See
https://github.com/tianocore/edk2-platforms/blob/master/Silicon/Hisilicon/Hi1616/D05AcpiTables/Dsdt/D05Sas.asl#L101
I know, I was just outlining the fact that some of the mbigen
ports are shared between devices, and MBI1 seems to be an example
of that (though my reading of ASL is... primitive).
Ah, ok. So this one is for the networking subsystem, and it does have
many devices in the topology model, but I can't claim to known much more
than that.
Thanks,
John
