Code of Conflict
|
||||
----------------
|
||||
|
||||
The Linux kernel development effort is a very personal process compared
|
||||
to "traditional" ways of developing software. Your code and ideas
|
||||
behind it will be carefully reviewed, often resulting in critique and
|
||||
criticism. The review will almost always require improvements to the
|
||||
code before it can be included in the kernel. Know that this happens
|
||||
because everyone involved wants to see the best possible solution for
|
||||
the overall success of Linux. This development process has been proven
|
||||
to create the most robust operating system kernel ever, and we do not
|
||||
want to do anything to cause the quality of submission and eventual
|
||||
result to ever decrease.
|
||||
|
||||
If however, anyone feels personally abused, threatened, or otherwise
|
||||
uncomfortable due to this process, that is not acceptable. If so,
|
||||
please contact the Linux Foundation's Technical Advisory Board at
|
||||
<tab@lists.linux-foundation.org>, or the individual members, and they
|
||||
will work to resolve the issue to the best of their ability. For more
|
||||
information on who is on the Technical Advisory Board and what their
|
||||
role is, please see:
|
||||
http://www.linuxfoundation.org/programs/advisory-councils/tab
|
||||
|
||||
As a reviewer of code, please strive to keep things civil and focused on
|
||||
the technical issues involved. We are all humans, and frustrations can
|
||||
be high on both sides of the process. Try to keep in mind the immortal
|
||||
words of Bill and Ted, "Be excellent to each other."

There are no valid reasons to use both enable_irq_wake() and the IRQF_NO_SUSPEND

There are very few valid reasons to use both enable_irq_wake() and the

same device.

Second, both enable_irq_wake() and IRQF_NO_SUSPEND apply to entire IRQs and not

to individual interrupt handlers, so sharing an IRQ between a system wakeup

interrupt source and an IRQF_NO_SUSPEND interrupt source does not make sense.

interrupt source and an IRQF_NO_SUSPEND interrupt source does not generally

make sense.

|

In rare cases an IRQ can be shared between a wakeup device driver and an

IRQF_NO_SUSPEND user. In order for this to be safe, the wakeup device driver
|

must be able to discern spurious IRQs from genuine wakeup events (signalling
|

the latter to the core with pm_system_wakeup()), must use enable_irq_wake() to
|

ensure that the IRQ will function as a wakeup source, and must request the IRQ
|
||||
with IRQF_COND_SUSPEND to tell the core that it meets these requirements. If
|

these requirements are not met, it is not valid to use IRQF_COND_SUSPEND.
