Can we do this slightly differently. smp_ipi_irq_setup() is just a helper 
anyways,
can we keep the interface the same (maybe explicit'ify that it takes hwirq). And
call irq_find_mapping() inside it - this will reduce the code churn !

So this series is missing the cover letter which makes it a bit hard to gauge 
the
end goal.
It seems patch [1-3]/5 are fixes which can be applied right away.
And [4-5]/5 help fix the irq affinity setting. What this doesn't say is which
platforms does it fix. And do we not need the hierarchical irq domains, 
specially
for the AXS platform which has 3 interrupt controllers stacked up.

Could you please pick this one up?
I may alternatively send a pull-request to David but not sure if 1 patch worth 
it.

Also if that's not really too late it would be good to get this one in 4.9 
since the patch
In question fixes a real driver crash on its instantiation.
Actually driver crash happens since 4.8 but I failed to notice it earlier and 
given amount
of changes I think there's barely a chance for it it to be accepted in stable 
branches...
which in its turn makes at least 4.9 very desirable.

[PATCH v2 4/5] ARC: MCIP: Set an initial affinity value in idu_irq_map

2016-10-24 Thread Yuriy Kolerov

Originally an initial distribution mode (its value resides in Device Tree)
for each common interrupt is set in idu_irq_xlate. This leads to the
following problems. idu_irq_xlate may be called several times during parsing
of the Device Tree and it is semantically wrong to configure an initial
distribution mode here. Also a value of affinity (CPUs bitmap) is not saved
to irq_desc structure for the virq - later (after parsing of the DT) kernel
sees that affinity is not set and sets a default value of affinity (all
cores in round robin mode). As a result a value of affinity from Device
Tree is ignored.

To fix it I created a buffer for initial CPUs bitmaps from Device Tree.
In idu_irq_xlate those bitmaps are saved to the buffer. Then affinity
for virq is set manually in idu_irq_map. It works because idu_irq_xlate
is always called before idu_irq_map.

Despite the fact that it works I think that it must be rewritten to
eliminate usage of the buffer and move all logic to idu_irq_map but
I do not know how to do it correctly.

[PATCH v2 3/5] ARC: MCIP: Use hwirq instead of virq for resolution of IDU IRQ handlers

2016-10-24 Thread Yuriy Kolerov

Multicore ARC configurations use IDU (Interrupt Distribution Unit) for
distributing of common interrupts. In fact IDU is a interrupt controller
on top of main per core interrupt controller.

All common IRQs are physically and linearly mapped to per core
interrupts. E.g. <0, 1, 2, 3> common IDU interrupts may be mapped to per
core <24, 25, 26, 27> interrupts. An initialization code of IDU
controller (idu_of_init) creates mappings for all parent interrupts
<24, 25, ...> and sets a chained IDU handler for them. In the same
time idu_of_init must save the first met parent hwirq (idu_first_irq)
thus in future it is possible to figure out what common hwirq has come
by subtracting of idu_first_irq from the current parent hwirq (see
idu_cascade_isr).

The problem is that idu_of_init and idu_cascade_isr use parent virtual
IRQs as hardware IRQs and perform all the above-described manipulations
on virtual IRQs. But it is wrong and hardware IRQs must be used instead.

[PATCH v2 2/5] ARC: SMP: Pass virq to smp_ipi_irq_setup instead of hwirq

2016-10-24 Thread Yuriy Kolerov

This function takes a cpu number and a virq number and registers an
appropriate handler per cpu. However smp_ipi_irq_setup is incorrectly
used in several places of ARC platform code - hwirq is passed instead of
virq. There is a code with an example of inccorect usage of smp_ipi_irq_setup:

smp_ipi_irq_setup(cpu, IPI_IRQ);
smp_ipi_irq_setup(cpu, SOFTIRQ_IRQ);

where IPI_IRQ and SOFTIRQ_IRQ are hwirq numbers for per cpu interrupts.
Since smp_ipi_irq_setup must be taken a virq number insdead of a hwirq
number then it is necessary to fix usage of this function this way:

smp_ipi_irq_setup(cpu, irq_find_mapping(NULL, IPI_IRQ));
smp_ipi_irq_setup(cpu, irq_find_mapping(NULL, SOFTIRQ_IRQ));

The idea is to find an appropriate mapping of  to virq
by using irq_find_mapping function. NULL value is used as a domain
argument (a default domain) since smp_ipi_irq_setup is used for
registering an IRQ handler for a root interrupt controller (a default
IRQ domain must be used).
