[PATCH v7 0/5] ACPI: hotplug messages improvement

From: Toshi Kani
Date: Tue Nov 20 2012 - 18:51:07 EST


This patchset improves logging messages for ACPI CPU, Memory,
Container and Dock hotplug notify handlers. The patchset
introduces a set of new macro interfaces, acpi_handle_<level>(),
and uses them to update the notify handlers.

acpi_handle_<level>() appends "ACPI" prefix and ACPI object path
to the messages, which has similar usage model as dev_<level>().
This improves diagnosis of hotplug operations since an error
message in a log file identifies an object that caused an issue.

The patchset is based on the linux-next branch of linux-pm.git
tree.

v7:
- Changed acpi_handle_printk() not to call acpi_get_name() in
interrupt context.

v6:
- Changed the interface name to acpi_handle_<level>(), and
declared them in include/linux/acpi.h.
- Added __printf(3,4) to acpi_handle_printk() prototype.
- Documented the interfaces acquire the global namespace mutex
and may not be called from interrupt context.

v5:
- Added update for ACPI Dock hotplug error messages.
- Added error status / ID info to the messages where needed.

v4:
- Changed to use dev_<level>() where it is appropriate.

v3:
- Changed acpi_pr_debug() to NOP when !DEBUG and !DYNAMIC_DEBUG.
DYNAMIC_DEBUG will be supported later when necessary.
- Added const to a path variable in acpi_printk().
- Added more descriptions to the change log of patch 1/4.

v2:
- Set buffer.pointer to NULL in acpi_printk().
- Added acpi_pr_debug().
