Subject: [PATCH v2 00/13] Kill off set_irq_flags

This series converts all users of ARM specific set_irq_flags to use
common genirq functions. set_irq_flags is just a wrapper around
irq_modify_status, so this simply removes the wrapper to directly call
irq_modify_status (or other helpers) and the translation from ARM
specific flags to genirq flags. The final irq flag states are unchanged.
In many cases where irqdomains are used, the set_irq_flags calls were
redundant, so I've removed them.

The last version has been run thru kernelci.org testing (thanks Kevin H!).
I plan to send this series through arm-soc. I still need acks from the To
list here.

This series is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git irqflags

v2 changes:
- Rebase to 4.2-rc1 and add acks
- Add xgene PCI conversion (added in 4.2)
- Fix build on clps711x

Subject: [PATCH v2 01/13] ARM: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Subject: [PATCH v2 02/13] clk: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Subject: [PATCH v2 05/13] gpu/drm: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Subject: [PATCH v2 07/13] memory: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Subject: [PATCH v2 09/13] PCI: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Subject: [PATCH v2 11/13] sh: kill off set_irq_flags usage

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.

Looking at the irq probe users:

drivers/input/touchscreen/ucb1400_ts.c
drivers/mfd/ucb1x00-core.c

The probe function was added in the initial implementation of the
driver (2006), so it predates device tree.

drivers/net/appletalk/ltpc.c
drivers/net/arcnet/com20020-isa.c
drivers/net/arcnet/com90io.c
drivers/net/arcnet/com90xx.c

Surely not stuff you find on todays ARM systems

drivers/net/ethernet/8390/ne.c
drivers/net/ethernet/8390/wd.c
drivers/net/ethernet/amd/lance.c
drivers/net/ethernet/amd/ni65.c
drivers/net/ethernet/amd/pcnet32.c

Ditto

drivers/net/ethernet/smsc/smc911x.c
drivers/net/ethernet/smsc/smc9194.c
drivers/net/ethernet/smsc/smc91x.c

Those might still be, but on the DT based boards the probing should be
completely irrelevant

drivers/net/hamradio/dmascc.c
drivers/net/wan/cosa.c
drivers/net/wan/sbni.c
drivers/parport/parport_pc.c

Surely not stuff you find on todays ARM systems

drivers/pcmcia/yenta_socket.c

Russell might still use that.

drivers/scsi/NCR53c406a.c
drivers/scsi/sym53c416.c
drivers/tty/cyclades.c

Surely not stuff you find on todays ARM systems

drivers/tty/serial/8250/8250_core.c

The irq probing is used by

mach-imx/mach-mx31ads.c
mach-iop32x/n2100.c

and X86

So in most of the irqchip drivers, this is irrelevant.

Thanks,

Please send the patches through the subsystem maintainers. I have
other irq related changes pending for more or less the same files. So
having one part in arm-soc and the other in drivers/* is not a really
good idea conflict wise.

We can remove the implementations right after 4.3-rc1. If susbsystems
have not picked up their lot when the merge window opens (i.e. not in
-next), we can feed them through tip/irq as I plan with the stuff I'm
sending out next week.

Thanks,

Both set and clear really. The state of IRQ_NOPROBE is a don't care in
most cases as you have outlined below. Are the cases of setting
IRQ_NOPROBE really needed or simply a bunch of copy and paste?

I've noticed I have a few places wrong with probe setting though, so
I'll be sending a v3.

We still have lots of platforms which are not (and probably never will
be) DT. Certainly, DT only irqchips should be easy to make consistent.
The older stuff is harder and not frequently tested.

Yes, these are quite common on ARM boards, and probably few if any
rely on irq probing regardless of DT.

Agreed, but that's a separate series I think. I'm trying not to change
behavior with this series. Are you proposing I do something different
with this patch?

As this works for several pxa boards :

No, consolidating it with no functional change is certainly the right
thing to do first.

pcnet32 is used on the Netwinder, which we still have supported in the ARM
tree. Even worse, the Netwinder has the Cyberpro capture IRQ missing a
resistor, so it defaults to "asserted" and can trigger a stuck-IRQ, so
it's best not to allow probing of that known bad IRQ.

SA11x0 stuff uses smc91x.c

Some EBSA285 systems use that, Compaq Personal Server (which is my wireless
AP using hostap) does.

ucb1x00.c definitely uses IRQ probing on SA11x0 platforms.

PXA uses it also for lubbock, mainstone and zylonite boards, which are not yet
converted to DT, and won't drop platform_data, even if they are DT converted.
I remember testing this patchset on lubbock at least.

> ucb1x00.c definitely uses IRQ probing on SA11x0 platforms.
For PXA I must admit I don't yet know. I know lubbock has an UCB1400, but I
don't have it working yet, so I can't foresee the problems yet.

Cheers.

The UCB1400 is an AC'97 device which is quite different from its
predecessors, and is not supported by the UCB1x00 driver.

I think it should be irq_set_probe(virq), I don't see why you inverted the probe flag.

Yes, this translation and similar ones are messed up. I've gone back
thru and fixed these.

However, it is questionable whether you really want to enable probing
on these lines or care either way.
