93e1821c - peci: Add peci-cpu driver

Tue, 08 Feb 2022 15:36:35 +0000

peci: Add peci-cpu driverPECI is an interface that may be used by different types of devices.Add a peci-cpu driver compatible with Intel processors. The driver isresponsible for handling auxiliary devices that can subsequently be usedby other drivers (e.g. hwmons).Reviewed-by: Pierre-Louis Bossart Acked-by: Joel Stanley Signed-off-by: Iwona Winiarska Link: https://lore.kernel.org/r/20220208153639.255278-10-iwona.winiarska@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/peci/Makefile

42bed52b - peci: Add sysfs interface for PECI bus

Tue, 08 Feb 2022 15:36:33 +0000

peci: Add sysfs interface for PECI busPECI devices may not be discoverable at the time when PECI controller isbeing added (e.g. BMC can boot up when the Host system is still in S5).Since we currently don't have the capabilities to figure out the Hostsystem state inside the PECI subsystem itself, we have to rely onuserspace to do it for us.In the future, PECI subsystem may be expanded with mechanisms that allowus to avoid depending on userspace interaction (e.g. CPU presence couldbe detected using GPIO, and the information on whether it's discoverablecould be obtained over IPMI).Unfortunately, those methods may ultimately not be available (supportwill vary from platform to platform), which means that we still needplatform independent method triggered by userspace.Acked-by: Joel Stanley Signed-off-by: Iwona Winiarska Link: https://lore.kernel.org/r/20220208153639.255278-8-iwona.winiarska@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/peci/Makefile

52857e68 - peci: Add device detection

Tue, 08 Feb 2022 15:36:32 +0000

peci: Add device detectionSince PECI devices are discoverable, we can dynamically detect devicesthat are actually available in the system.This change complements the earlier implementation by rescanning PECIbus to detect available devices. For this purpose, it also introduces theminimal API for PECI requests.Reviewed-by: Pierre-Louis Bossart Acked-by: Joel Stanley Signed-off-by: Iwona Winiarska Link: https://lore.kernel.org/r/20220208153639.255278-7-iwona.winiarska@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/peci/Makefile

a85e4c52 - peci: Add peci-aspeed controller driver

Tue, 08 Feb 2022 15:36:31 +0000

peci: Add peci-aspeed controller driverASPEED AST24xx/AST25xx/AST26xx SoCs support the PECI electricalinterface (a.k.a PECI wire) that provides a communication channel withIntel processors.This driver allows BMC to discover devices connected to it andcommunicate with them using PECI protocol.Co-developed-by: Iwona Winiarska Reviewed-by: Pierre-Louis Bossart Reviewed-by: Joel Stanley Acked-by: Joel Stanley Signed-off-by: Jae Hyun Yoo Signed-off-by: Iwona Winiarska Link: https://lore.kernel.org/r/20220208153639.255278-6-iwona.winiarska@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/peci/Makefile

6523d3b2 - peci: Add core infrastructure

Tue, 08 Feb 2022 15:36:30 +0000

peci: Add core infrastructureIntel processors provide access for various services designed to supportprocessor and DRAM thermal management, platform manageability andprocessor interface tuning and diagnostics.Those services are available via the Platform Environment ControlInterface (PECI) that provides a communication channel between theprocessor and the Baseboard Management Controller (BMC) or otherplatform management device.This change introduces PECI subsystem by adding the initial core moduleand API for controller drivers.Co-developed-by: Jason M Bills Co-developed-by: Jae Hyun Yoo Reviewed-by: Pierre-Louis Bossart Acked-by: Joel Stanley Signed-off-by: Jason M Bills Signed-off-by: Jae Hyun Yoo Signed-off-by: Iwona Winiarska Link: https://lore.kernel.org/r/20220208153639.255278-5-iwona.winiarska@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/peci/Makefile
