This is an patch set to optimize irq flow handler. It could be split
into three part.
1) Patch 1-12 get rid of redundant looking up of irq_desc and irq_data
when we already had an pointer to corresponding irq_desc in irq
flow handler. This part should be pretty safe.
2) Patch 13 is a perparation patch.
3) Patch 14-25 should be merge into one big fat patch, which kills
the first parameter 'irq' of irq_flow_handler_t. I hope I have
made all needed changes, but there are still some handler missed.
After the conversion, there are only about 20 irq handlers which
really access the irq number. This part is still in early stage
and may cause building failures.
Please comment on whether we should be go on with the third part to
kill 'irq' of irq_flow_handler_t.

This is an patch set to optimize irq flow handler. It could be split
into three part.
1) Patch 1-12 get rid of redundant looking up of irq_desc and irq_data
when we already had an pointer to corresponding irq_desc in irq
flow handler. This part should be pretty safe.
2) Patch 13 is a perparation patch.
3) Patch 14-25 should be merge into one big fat patch, which kills
the first parameter 'irq' of irq_flow_handler_t. I hope I have
made all needed changes, but there are still some handler missed.
After the conversion, there are only about 20 irq handlers which
really access the irq number. This part is still in early stage
and may cause building failures.
Please comment on whether we should be go on with the third part to
kill 'irq' of irq_flow_handler_t.
Thanks!

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.
Do the same thing to avoid pattern "irq_get_chip_data(data->irq)".

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.
Also replace generic_handle_irq with generic_handle_irq_desc() to avoid
looking up irq_desc again.

looking up irq_desc again.

The first parameter 'irq' is never used by kstat_incr_irqs_this_cpu(),
so kill it. So one step further to kill the first parameter 'irq'
of irq_flow_handler_t.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

* [RFC v1 15/25] genirq: Kill the first parameter 'irq' of irq_flow_handler_t
@ 2015-05-20 10:00 ` Jiang Liu
0 siblings, 0 replies; 120+ messages in thread
From: Jiang Liu @ 2015-05-20 10:00 UTC (permalink / raw)
To: linux-arm-kernel
Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

* [RFC v1 16/25] genirq: Kill the first parameter 'irq' of irq_flow_handler_t
@ 2015-05-20 10:00 ` Jiang Liu
0 siblings, 0 replies; 120+ messages in thread
From: Jiang Liu @ 2015-05-20 10:00 UTC (permalink / raw)
To: linux-arm-kernel
Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

* [RFC v1 23/25] genirq: Kill the first parameter 'irq' of irq_flow_handler_t
@ 2015-05-20 10:00 ` Jiang Liu
0 siblings, 0 replies; 120+ messages in thread
From: Jiang Liu @ 2015-05-20 10:00 UTC (permalink / raw)
To: linux-arm-kernel
Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.

This looks wrong. It's a redirector of irq to some other irq.
redir_irq = (unsigned int)irq_get_handler_data(irq);
which should be:
redir_irq = (unsigned int)irq_desc_get_irq_handler_data(desc);
And redir_irq is certainly not the same as irq. So this wants a
conversion to irq_desc_get_irq_handler_data() first. That makes the
irq argument unused.

Hi Thomas,
Will check the base again.
Please do not apply patch after [14/25]. There are here to
ask for comments, there are still building issues with patch after
[14/25]. Just help to comment whether it's on the right direction.
If so, I will send another version for formal review.
Thanks!

That should be OK, 'irq' here is just a local variable.
Actually it may be changed as:
if (req) {
/* generate the next interrupt(s) */
- irq = lchip->irq_base;
+ unsigned int irq = lchip->irq_base;
for (i = 0; i <= 3; i++, irq++) {
if (req & (0x0100 << i)) {
generic_handle_irq(irq);
}
}

That should be OK, 'irq' here is just a local variable.
Actually it may be changed as:
if (req) {
/* generate the next interrupt(s) */
- irq = lchip->irq_base;
+ unsigned int irq = lchip->irq_base;
for (i = 0; i <= 3; i++, irq++) {
if (req & (0x0100 << i)) {
generic_handle_irq(irq);
}
}
}

Why initializing? It's overwritten in the loop.

Hi Thomas,
I'm not familiar with the hardware, but if src2map() returns 0
on the first call, we need to initialize irq. Otherwise
generic_handle_irq(irq) will use random value on the first call.
---------------------------------------------------------
map = src2map(32 * i + line);
if (map)
irq = map->irq;
---------------------------------------------------------
Thanks!

I think you are doing that conversion wrong. You should first change
all handlers which use the irq argument to:
handler(unsigned __irq, *desc)
and add the local variable
unsigned irq;
or
unsigned irq = irq_desc_get_irq(desc);
for those.
So that results in a pretty small series of patches.
Once that is done, you can remove the irq argument in one go treewide.
And you should do that with scripting aid. Coccinelle is the proper
tool for this. If you have problems with cocci, you can politely ask
Julia (Cc'ed) for help. She's the master of coccinelle :)
The purpose of the script is to:
1) Identify all handlers
This can be done by analyzing the arguments of
__irq_set_handler()
irq_set_handler()
irq_set_chained_handler()
irq_alloc_generic_chip()
irq_alloc_domain_generic_chips()
irq_set_chip_and_handler_name()
irq_set_chip_and_handler()
__irq_set_handler_locked()
__irq_set_chip_handler_name_locked()
__irq_set_preflow_handler()
If the argument is a function local to the file step 2 can
take place.
If it's a extern function, then the script should at least
print out the function names. Those are in most of the cases
the generic flow handler functions.
2) Check the handlers whether they use the irq argument
For those which do:
Check whether they just use the argument instead of a local
variable, i.e. the first usage is an assignment. In that
case rename the argument to __irq and add a local variable
unsigned int irq;
If they use the irq argument for some computation or as
argument to another function, then you need to rename the
argument as well and add:
unsigned int irq = irq_get_desc_irq(desc);
So this results in a series of patches which can be merged right
away. If that lot has hit Linus tree and right after -rc1, we run the
script again and find and fix stuff which got added throughout the
merge window. That might result in 0 to n patches.
The last step is another script which does:
1) Identify all handlers
2) Remove the irq argument
We can send that right after -rc1 so no new users can trickle in.
It's really important to do that with scripts. It seems you try to do
it via compile testing. But that will fail as you CANNOT execute all
possible config combinations.
Thanks,
tglx

You omitted the following code:
raw_spin_unlock(&bank_lock);
if (!map) {
pr_err("IPU: Interrupt on unmapped source %u bank %d\n",
line, i);
continue;
}
So you it does not use irq if map is 0.

Scripting this may be a little complex, because the variable can be used
in one way in one execution path (eg if branch) and another way (or not at
all) in another. Let me know if help is needed.

I feared that, but at least identifying all functions, where the irq
argument is used inside the function itself is really key for such a
massive rework.

It's not impossible, but I may need to think a bit how best to do it.

I pretty much expected that you would say that :)
But seriously, the first important thing is to find all functions and
to check whether they use irq internaly. Jiang has done that
'manually' or such, so the number of function which need an actual
change are not that big.
But I certainly don't want to hold you off thinking about it. Such
stuff is not a unique problem :)

Hi Linus,
Thanks for review.
There's a very long dependency list of this patch set,
so it would be safer to merge this patch set altogether through
the irq tree if that works:)

What is the status of this? I am close to having a semantic patch that
works. The current version touches 133 files, but I haven't checked all
of them. This includes both the local functions and the generic ones, but
not the cases where the name of the handler function is a local variable
or arbitrary expression. This occurs in around 30 files.

Jiang sent out a new patch series, but I'm really interested in doing
a fully automated check. If conversion is possible for some of them,
fine, but the checking part to find all the places where this needs to
be applied is the most important to me.
If you want, just send me that script and I'll give it a test ride.
Thanks,

The results are attached. The semantic patch is below. This should be
run with the argument --in-place. You need to have ocaml installed.

> unsigned irq = irq_desc_get_irq(desc);
Actually, it seems that this function doesn't exist in linux-next either.
What is the correct name of the function, or is there some other tree that

julia

That's a new helper function, which is introduced in that series.

Great thanks to you, Julia!
It seems really attractively, I will try to figure out
whether I have caught all the cases.
BTW, a new version of these patch set has been posted at:
http://comments.gmane.org/gmane.linux.kernel.pci/42320
I have also push the new version to github in case you need
to access it:
https://github.com/jiangliu/linux.git irq:irqdesc_v2
Thanks!

The following are the cases that require some manual attention, either
because the handler is a local variable or because it is some other kind
of expression.

yep, found it in the logs already and found a missing search expression:

This is really impressive work!!!!

Thanks :)
I'll add the above pattern, but I guess you already have the results for
that case.

The semantic patch below considers the problem from another point of view,
to find functions that may have a handler as an argument. The results
that are different than those considered already are as follows:
arch/x86/platform/uv/uv_irq.c:106 irq_domain_set_info
has a possible handler in argument 6
arch/sparc/kernel/leon_pci_grpci2.c:815 leon_update_virq_handling
has a possible handler in argument 2
arch/sparc/kernel/leon_kernel.c:79 leon_build_device_irq
has a possible handler in argument 2
arch/arm/mach-omap2/prm_common.c:331 irq_alloc_generic_chip
has a possible handler in argument 5
arch/mips/cavium-octeon/octeon-irq.c:1231 octeon_irq_set_ciu_mapping
has a possible handler in argument 6
arch/blackfin/mach-common/ints-priority.c:805 bfin_set_irq_handler
has a possible handler in argument 2
arch/m68k/q40/q40ints.c:84 m68k_setup_irq_controller
has a possible handler in argument 2
drivers/gpio/gpio-pcf857x.c:362 gpiochip_irqchip_add
has a possible handler in argument 4
The semantic patch looks for a function that has as argument a function
that has arguments of type (unsigned int irq, struct irq_desc *desc) and a
void return type. It also looks for functions that have as argument a
bunch of known irq handlers.

Yes.
I did some more experiments and analyzed all functions which have the
signature
[static] void f(T irq, struct irq_desc *desc)
where T is either 'unsigned int' or 'u32'
That throws up a handful of false positives, but those are functions
which are called from a real handler function, so we want to look at
those anyway.
Now where my cocci foo ends is when I try to match both types in the
same rule, i.e.
@ fun exists @
identifier hf,irq,desc;
typedef u32;
@@
(
void hf(unsigned irq, struct irq_desc *desc) { ... }
|
void hf(u32 irq, struct irq_desc *desc) { ... }
)
results in:
Fatal error: exception Failure("minus: parse error:
= File "../cocci/find-pot-handler.cocci", line 7, column 5, charpos = 63
around = 'hf', whole content = void hf(unsigned irq, struct irq_desc *desc) { ... }
")
I tried a couple of other variants, but finally gave up and ran a
cocci script first which does s/u32/unsigned/ on those functions, but
of course because I'm lazy I wanted to do everything in one go. :)
Aside of that the ruleset you gave me works nicely except for that
part:
// no uses of the first parameter before the assignment
@@
identifier fun.hf,irq;
expression e;
type T;
fresh identifier firq = "__" ## irq;
position r.p,p1 != {s.p1,s1.p1};
@@
hf(T@p
- irq
+ firq
,...) {
... when != irq
when strict
? irq@p1 = e
... when any
}
That lacks a:
+ unsigned int irq;
and therefor missed to add the local variable 'unsigned int irq' in
case the parameter is only used for local storage.
That was simple enough to fix even for me :)
Thanks,
tglx

Yeah, sorry, it doesn't work. There is no way to put a disjunction on
a function definition or a parameter type.
