When using /proc/interrupts to collect statistics on smp2p interrupt counts, it is hard to distinguish the different instances of smp2p from each other. For example to debug a processor boot issue, the ready and handover interrupts are checked for sanity to ensure the firmware reached a specific initialization stage. Remove "smp2p" string from the irq request so that the irq will default to the device name. Add an .irq_print_chip() callback to print the irq chip name as the device name. These two changes allow for a unique name to be used in /proc/interrupts as shown below. / # cat /proc/interrupts | grep smp2p 18: ... ipcc 196610 Edge smp2p-adsp 20: ... ipcc 131074 Edge smp2p-modem 170: ... smp2p-modem 1 Edge q6v5 ready 178: ... smp2p-adsp 1 Edge q6v5 ready Signed-off-by: Chris Lew <quic_clew@quicinc.com> Reviewed-by: Konrad Dybcio <konrad.dybcio@linaro.org> Link: https://lore.kernel.org/r/20240627104831.4176799-2-quic_sudeepgo@quicinc.com Signed-off-by: Bjorn Andersson <andersson@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
