Changes in sysfs-kernel-irq en Copyright 2015 Java d61e2944 - genirq: Add wakeup sysfs node to show IRQ wakeup state http://172.16.0.5:8080/history/linux-6.15/Documentation/ABI/testing/sysfs-kernel-irq#d61e2944 genirq: Add wakeup sysfs node to show IRQ wakeup stateSurprisingly there is no simple way to see if the IRQ line in questionis wakeup source or not.Note that wakeup might be an OOB (out-of-band) source like GPIO linewhich makes things slightly more complicated.Add a sysfs node to cover this case.Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>Signed-off-by: Thomas Gleixner <tglx@linutronix.de>Tested-by: Tony Lindgren <tony@atomide.com>Cc: Grygorii Strashko <grygorii.strashko@ti.com>Cc: "Rafael J .

It also has varying column numbers depending on hardware.That all makes it hard for tools to parse.To solve this, expose the information through sysfs so each irq attributeis in a separate file in a consistent, machine parsable way.This feature is only available when both CONFIG_SPARSE_IRQ andCONFIG_SYSFS are enabled.Examples: /sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7 /sys/kernel/irq/18/chip_name: IR-IO-APIC /sys/kernel/irq/18/hwirq: 18 /sys/kernel/irq/18/name: fasteoi /sys/kernel/irq/18/per_cpu_count: 0,0 /sys/kernel/irq/18/type: level /sys/kernel/irq/25/actions: ahci0 /sys/kernel/irq/25/chip_name: IR-PCI-MSI /sys/kernel/irq/25/hwirq: 512000 /sys/kernel/irq/25/name: edge /sys/kernel/irq/25/per_cpu_count: 29036,0 /sys/kernel/irq/25/type: edge[ tglx: Moved kobject_del() under sparse_irq_lock, massaged code comments and changelog ]Signed-off-by: Craig Gallek <kraig@google.com>Cc: David Decotigny <decot@google.com>Link: http://lkml.kernel.org/r/1473783291-122873-1-git-send-email-kraigatgoog@gmail.comSigned-off-by: Thomas Gleixner <tglx@linutronix.de> List of files: /linux-6.15/Documentation/ABI/testing/sysfs-kernel-irq Tue, 13 Sep 2016 16:14:51 +0000 Craig Gallek <kraig@google.com>
