Special configuration (either kernel command line or sysfs-based) is needed to see the messages printed by them and the format of those messages is also special and convoluted. For this reason, replace all of the ACPI_DEBUG_PRINT() and ACPI_EXCEPTION() instances in the ACPI processor driver with corresponding dev_*(), acpi_handle_*() and pr_*() calls depending on the context in which they appear. Also drop the ACPI_PROCESSOR_COMPONENT definition that is not going to be necessary any more. Signed-off-by: Rafael J.

While at it, add a pr_fmt() definition ot pci_link.c, make acpi_pci_link_check_possible() print all messages with acpi_handle_debug() for consistency and replace the (not-so- reliable) KERN_CONT-based message line composition in acpi_pci_link_add() with two pr_info() and a series of acpi_handle_debug() calls (the latter for the possible IRQs).

The majority of them are printed with the help of the dev_*() familiy of logging functions, but ACPI_DEBUG_PRINT() and ACPI_DEBUG_PRINT_RAW() are still used in some places which requires the ACPICA debug to be enabled additionally which is a nuisance and one message is printed using the raw printk(). To consolidate the printing of messages in that code, convert all of the ACPI_DEBUG_PRINT() instances in it into dev_dbg(), which is consistent with the way the other messages are printed by it, replace the only ACPI_DEBUG_PRINT_RAW() instance with pr_debug() and make it use pr_warn() istead of printk(KERN_WARNING ). Also add a pr_fmt() definition to that file and drop the _COMPONENT and ACPI_MODULE_NAME() definitions that are not used any more after the above changes. Signed-off-by: Rafael J.

It was rendered all but unusable by making its attributes privileged-only to work around a security issue. A suggested remedy was rejected by AMD, so the only real solution was to remove the driver. For the future, we'll have to make sure that no privileged-access-only drivers are accepted into the hwmon subsystem in the first place. The hwmon ABI document was updated accordingly. Other changes: PMBus drivers: - Added driver for MAX15301 - Added driver for BluTek BPA-RS600 - Added driver for fsp-3y PSUs and PDUs - Added driver for Infineon IR36021 - Added driver for ST STPDDC60 - Added support for TI TPS53676 to tps53679 driver - Introduced PMBUS symbol namespace. This was made necessary by a suggestion to use its exported functions from outside the hwmon subsystem. - Minor improvements and bug fixes New drivers: - Driver for NZXT Kraken X42/X52/X62/X72 Driver enhancements: - Added support for Intel D5005 to intel-m10-bmc-hwmon driver - Added support for NCT6686D to nct6683 driver Other: - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info() - Added support for fan drawers capability and present registers to mlxreg-fan driver - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver - Replaced snprintf in show functions with sysfs_emit.

The attack is described in 'PLATYPUS: Software-based Power Side-Channel Attacks on x86'. It relies on quick and accurate energy readings. This change made the counters provided by the amd_energy driver effectively unusable for non-provileged users. However, unprivileged read access is the whole point of hardware monitoring attributes. An attempt to remedy the situation by limiting and randomizing access to chip registers was rejected by AMD. Since the driver is for all practical purposes unusable, remove it.

For example, writes to the PAGE command requires using PEC, otherwise the write won't work and the page won't switch, even though, the standard says that PEC is optional. On the other hand, writes to SMBALERT don't require PEC. Because of this, the driver is mostly reverse engineered with the help of a tool called pmbus_peek written by David Brownell (and later adopted by my colleague Jan Kundrát). The device also has some sort of a timing issue when switching pages, which is explained further in the code. Because of this, the driver support is limited. It exposes only the values that have been tested to work correctly.

Convert driver to use hwmon_device_register_with_info() and remove sysfs attributes which are now being handled by the hwmon subsystem. Channel handling was inspired by corsair-cpro. Tested on a Fujitsu Esprimo P720.

Some systems are equipped with fan drawers with one tachometer inside. Others with fan drawers with several tachometers inside. Using present register along with tachometer-to-drawer mapping allows to skip reading missed tachometers and expose input for them as zero, instead of exposing fault code returned by hardware.
