Cc: Thomas Gleixner
While trying to understand internals of irq handling, came across a
thread [1] in which tglx was referring to avoid usage of setup_irq().
The early boot setup_irq() invocations happen either via 'init_IRQ()'
or 'time_init()', while memory allocators are ready by 'mm_init()'.
Hence instances of setup_irq() are replaced by request_irq() &
setup_irq() [along with remove_irq()] definition deleted in the last
patch.
Seldom remove_irq() usage has been observed coupled with setup_irq(),
wherever that has been found, it too has been replaced by free_irq().
Build & boot tested on ARM & x86_64 platforms (ensured that on the
machines used for testing, modifications made in this series is being
exercised at runtime)
Much of the changes were created using Coccinelle with an intention
to learn it. But not everything could be automated.
Searching with 'git grep -n '\Wsetup_irq('' & avoiding the irrelevant
ones, 153 invocation's of setup_irq() were found. 112 could be replaced
w/ cocci, of which in a few files some desired hunks were missing or
not as expected, these were fixed up manually. Also the remaining 41
had to be done manually.
Although cocci could replace 112, because of line continue not
happening at paranthesis for request_irq(), around 80 had to be
manually aligned in the request_irq() statement.
So though many changes could be automated, there are a considerable
amount of manual changes, please review carefully especially mips &
alpha.
Usage of setup_percpu_irq() is untouched w/ this series.
There are 2 checkpatch warning about usage of BUG(), they were already
present w/ setup_irq(), status quo maintained.

Since changes from v1 are trivial as below, tags received has been
applied to the relevant patches, if any objections, please shout.
v2:
* Replace pr_err("request_irq() on %s failed" by
pr_err("%s: request_irq() failed"
* m68k: remove now irrelevant comment separation comment lines
* Commit message massage

In cover letter, there was "base-commit: v5.6-rc1", test robot cannot make use of that information ?, since my thought was that your script would create a branch with any valid start point following "base-commit:" > drivers/clocksource/timer-prima2.c: In function 'sirfsoc_prima2_timer_init': > >> drivers/clocksource/timer-prima2.c:213:2: error: 'sirfsoc_timer_irq' undeclared (first use in this function); did you mean 'sirfsoc_timer_read'? > sirfsoc_timer_irq.irq = irq_of_parse_and_map(np, 0); > ^~~~~~~~~~~~~~~~~ > sirfsoc_timer_read > drivers/clocksource/timer-prima2.c:213:2: note: each undeclared identifier is reported only once for each function it appears in Does the robot keep the log of patches that are successfully built ?, w/ v1, i did not receive similar report, and tried to find if test robot has successfully built v1, but couldn't find out.

* [PATCH v3 16/18] clocksource: Replace setup_irq() by request_irq() 2020-02-25 2:52 ` kbuild test robot 2020-02-25 7:51 ` afzal mohammed @ 2020-02-27 10:59 ` afzal mohammed 2020-02-27 11:18 ` Daniel Lezcano 1 sibling, 1 reply; 9+ messages in thread From: afzal mohammed @ 2020-02-27 10:59 UTC (permalink / raw) To: linux-kernel, linux-arm-kernel, linux-samsung-soc, linux-amlogic Cc: Daniel Lezcano, Thomas Gleixner, Florian Fainelli, Ray Jui, Scott Branden, bcm-kernel-feedback-list, Nicolas Saenz Julienne, Kukjin Kim, Krzysztof Kozlowski, Shawn Guo, Sascha Hauer, Pengutronix Kernel Team, Fabio Estevam, NXP Linux Team, Barry Song, Uwe Kleine-König, Kevin Hilman, Linus Walleij, Tony Prisk, Allison Randal, Enrico Weigelt, Greg Kroah-Hartman, Kate Stewart request_irq() is preferred over setup_irq(). The early boot setup_irq() invocations happen either via 'init_IRQ()' or 'time_init()', while memory allocators are ready by 'mm_init()'. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). Seldom remove_irq() usage has been observed coupled with setup_irq(), wherever that has been found, it too has been replaced by free_irq(). A build error that was reported by kbuild test robot <lkp@intel.com> in the previous version of the patch also has been fixed. [1] https://lkml.kernel.org/r/alpine.DEB.2.20.1710191609480.1971@nanos Signed-off-by: afzal mohammed <afzal.mohd.ma@gmail.com> --- Hi, There was a build error in v2, which was reported by kbuild test robot and it was suggested to add Reported-by to the patch. But since the change is being fixed up w/ original patch, if i add Reported-by, it will give a feeling as though robot has reported the necessity of this patch as whole, so i have credited test robot in a different way in the commit message. If the proper way is to add Reported-by tag itself or some other way, let me know, i will change accordingly. Hi Daniel, Linus, i have removed your Acked-by's as now patch has been modified (though only slightly the file timer-prima2.c) to fix the build error.

One of the check is to ensure that non-NULL dev_id is passed in the case of shared irq. Fix it by passing non-NULL dev_id while registering the shared irq.
