[PATCH V9 0/3] irqchip: qcom: Add IRQ combiner driver

[PATCH V9 0/3] irqchip: qcom: Add IRQ combiner driver

[Agustin Vega-Frias]

Add support for IRQ combiners in the Top-level Control and Status
Registers (TCSR) hardware block in Qualcomm Technologies chips.

The first patch prevents the ACPI core from attempting to map IRQ resources
with a valid ResourceSource as GSIs.

The first patch adds support for ResourceSource/IRQ domain mapping and
fixes IRQ probe deferral by allowing platform_device IRQ resources to be
re-initialized from the corresponding ACPI IRQ resource.

Both changes described above are conditional on the ACPI_GENERIC_GSI config.

The third patch takes advantage of the new capabilities to implement
the driver for the IRQ combiners.

Tested on top of v4.9.

Changes V8 -> V9:
* Do not attempt the mapping for non-GSI IRQs during bus scan.
* Make some public APIs private to drivers/acpi/irq.c since they are no
  longer used on other modules.

Changes V7 -> V8:
* Reorder patches to allow all new code to be under drivers/acpi/irq.c.
* Change acpi_irq_get implementation to be more similar to of_irq_get
  to improve maintainability.

[PATCH V9 1/3] ACPI: Generic GSI: Do not attempt to map non-GSI IRQs during bus scan

[Agustin Vega-Frias]

ACPI extended IRQ resources may contain a Resource Source field to specify
an alternate interrupt controller, attempting to map them as GSIs is
incorrect, so just disable the platform resource.

Since this field is currently ignored, we make this change conditional
on CONFIG_ACPI_GENERIC_GSI to keep the current behavior on x86 platforms,
in case some existing ACPI tables are using this incorrectly.

Well, patch is simple there is not much to say other that on the
firmware side I honestly do not see many options, either we remove the
ifdeffery above and make the check unconditional (ie we do check on
x86/ia64 too instead of always returning true) and see if things hold up
on x86 (at least we try) or we will never know and will never be able to
use this on x86 if there will ever be need.

It would be certainly weird to find out that a descriptor has a
resource_source pointer put there by mistake (because that's what we are
talking about, things work on x86/ia64 by ignoring the resource_source
pointer so any string there is just an unfortunate mistake AFAICS).

I am quite tempted to remove the ifdef and make the is_gsi() check effective on
x86/ia64 too.

I wouldn't be opposed to that. I added the #ifdef out of abundance of 
caution,
but if the x86 folks agree and we can get sufficient testing to ensure 
this
doesn't break anything I'd like to remove it too.

As pointed out by Lorenzo, if the interrupt resource is a Resource Producer,
it's not GSI, so maybe the code needs to be updated as

-   return ext_irq->resource_source.string_length == 0;
+ return ext_irq->resource_source.string_length == 0 &&
+        ext_irq->producer_consumer != ACPI_PRODUCER;

Agreed. I'll add the check.

[PATCH V9 2/3] ACPI: Add support for ResourceSource/IRQ domain mapping

[Agustin Vega-Frias]

ACPI extended IRQ resources may contain a ResourceSource to specify
an alternate interrupt controller. Introduce acpi_irq_get and use it
to implement ResourceSource/IRQ domain mapping.

The new API is similar to of_irq_get and allows re-initialization
of a platform resource from the ACPI extended IRQ resource, and
provides proper behavior for probe deferral when the domain is not
yet present when called.

If it's an interrupt producer, I think we don't need to map the interrupts in
any irqdomain, and return AE_CTRL_TERMINATE here.

        case ACPI_RESOURCE_TYPE_EXTENDED_IRQ:
                eirq = &ares->data.extended_irq;
+         if (eirq->producer_consumer == ACPI_PRODUCER)

Agreed. I'll add the check. However, we need to return AE_OK, not
AE_CTRL_TERMINATE, since that terminates the walk and there might
be other resources to check after this one.

Yes, thanks for the correction, there might be other Interrupt()
resources under _CRS which needs to be scanned.

[PATCH V9 3/3] irqchip: qcom: Add IRQ combiner driver

[Agustin Vega-Frias]

Driver for interrupt combiners in the Top-level Control and Status
Registers (TCSR) hardware block in Qualcomm Technologies chips.

An interrupt combiner in this block combines a set of interrupts by
OR'ing the individual interrupt signals into a summary interrupt
signal routed to a parent interrupt controller, and provides read-
only, 32-bit registers to query the status of individual interrupts.
The status bit for IRQ n is bit (n % 32) within register (n / 32)
of the given combiner. Thus, each combiner can be described as a set
of register offsets and the number of IRQs managed.

I'm a bit worried by this. If I understand it well, this is a pure
software construct (controlled from combiner_irq_chip_{un,}mask_irq) and
there is nothing that actually masks the interrupt at the HW level.

So if a device asserts its interrupt line, what mechanism do we have to
make sure that we don't end-up with the CPU pegged in interrupt context?

Small bug: virq == 0 shouldn't happen, since this would be an indication
that the hwirq doesn't have a mapping.

Given that this should have come from the translate function, can we
move the check there instead, so that we validate everything early?

Other than the questions I have above, this now looks in a much better
shape. Hopefully Rafael will soon come back will his conclusions on the
first two patches, as I'd like to see this code to get some -next for a
while.

Yes, unfortunately this is a dumb hardware combiner; however, the real 
use
of mask here is to optimize IRQ handling if the combiner instance has 
its
IRQ statuses across more than one register. Currently all active 
instances
only use one register, but we are getting close to 32 in one case, so I
wanted to accommodate a general case where an instance can combine more
than 32 IRQs.

Having said that, what I'm inclined to do is to remove the use of mask
on the status read form the register on the next two lines, and then let
irq_find_mapping fail if we are getting an unexpected IRQ, then call
handle_bad_irq(desc).

Do you have any other suggestions to handle the scenario? E.g., can we
safely disable the parent IRQ from this context if we see too many
spurious interrupts?

Unfortunately, having a mapping in place is not an indication that
someone can handle the interrupt. Also, you still need to handle
mask/unmask, and I don't see how you manage that, given that this
interrupt combiner seems to be a glorified OR gate.

I don't think so. There is two issues here:
- If a device is stuck with an active interrupt, you won't be able to
reliably detect that this is an invalid condition (the mapping trick
above is not reliable, and generic_handle_irq doesn't return anything
useful)
- Even if you could detect it, what do you do? Killing the cascade
interrupt would also kill all the other devices. Is that something
acceptable in your setup? Can you implement mask/unmask the same way?

Thanks,

Pinging again. Do you have any questions that might help with your
review? I have some minor changes I have to make to the driver itself
(patch 3) and I'd like to submit any changes you might want along with
those.

I'd like to add that these two initial patches are now a prerequisite
for Hanjun's series, so it'd be good to have an idea of where we're
going on that front.

Thanks,

Is it helpful to test patch [1-2/3] on x86 machines (with different firmware) and
an IA64 machine (surely a different version of firmware :) ) with Lorenzo's suggestion
of removing  #ifdef CONFIG_ACPI_GENERIC_GSI for is_gsi()? If yes, I can do that as
I have such machines.

Thanks
Hanjun

Well, it is always helpful, as helpful as getting this change into -next
as soon as possible, at the end of the day it is quite simple, as soon
as (hopefully never) we find some firmware out there (x86/ia64) that
misused the resource source field in the interrupt descriptor we will
have to add that guard back, it is as simple as that.

Thanks,
Lorenzo

As I said, I tested patch [1-2/3] with or without #ifdef CONFIG_ACPI_GENERIC_GSI for is_gsi()
on a x86 machine [1] and IA64 machine [2], both work fine as before, and no regressions in
the boot log.

Thanks
