[PATCH] drm/i915: use in_interrupt() not in_irq() to check context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The kernel in_irq() function tests for hard-IRQ context only, so if a
system is run with the kernel 'threadirqs' option selected, the test in
intel_check_page_flip() generates lots of warnings, because then it gets
called in soft-IRQ context.

We can instead use in_interrupt() which allows for either type of
interrupt, while still detecting and complaining about misuse of the
page flip code if it is ever called from non-interrupt context.
