6e085e0a - arm/arm64: Probe for the presence of KVM hypervisor

Wed, 09 Dec 2020 06:09:24 +0000

arm/arm64: Probe for the presence of KVM hypervisorAlthough the SMCCC specification provides some limited functionality fordescribing the presence of hypervisor and firmware services, this isgenerally applicable only to functions designated as "Arm ArchitectureService Functions" and no portable discovery mechanism is provided forstandard hypervisor services, despite having a designated range offunction identifiers reserved by the specification.In an attempt to avoid the need for additional firmware changes everytime a new function is added, introduce a UID to identify the serviceprovider as being compatible with KVM. Once this has been established,additional services can be discovered via a feature bitmap.Reviewed-by: Steven Price Signed-off-by: Will Deacon Signed-off-by: Jianyong Wu [maz: move code to its own file, plug it into PSCI]Signed-off-by: Marc Zyngier Link: https://lore.kernel.org/r/20201209060932.212364-2-jianyong.wu@arm.com List of files: /linux-6.15/drivers/firmware/smccc/Makefile

821b67fa - firmware: smccc: Add ARCH_SOC_ID support

Thu, 25 Jun 2020 09:59:39 +0000

firmware: smccc: Add ARCH_SOC_ID supportSMCCC v1.2 adds a new optional function SMCCC_ARCH_SOC_ID to obtain aSiP defined SoC identification value. Add support for the same.Also using the SoC bus infrastructure, let us expose the platformspecific SoC atrributes under sysfs.There are various ways in which it can be represented in shortened formfor efficiency and ease of parsing for userspace. The chosen form isdescribed in the ABI document.Link: https://lore.kernel.org/r/20200625095939.50861-1-sudeep.holla@arm.comCc: Etienne Carriere Reviewed-by: Steven Price Signed-off-by: Sudeep Holla List of files: /linux-6.15/drivers/firmware/smccc/Makefile

f2ae9706 - firmware: smccc: Refactor SMCCC specific bits into separate file

Mon, 18 May 2020 09:12:20 +0000

firmware: smccc: Refactor SMCCC specific bits into separate fileIn order to add newer SMCCC v1.1+ functionality and to avoid clutteringPSCI firmware driver with SMCCC bits, let us move the SMCCC specificdetails under drivers/firmware/smccc/smccc.cWe can also drop conduit and smccc_version from psci_operations structureas SMCCC was the sole user and now it maintains those.No functionality change in this patch though.Signed-off-by: Sudeep Holla Tested-by: Etienne Carriere Reviewed-by: Etienne Carriere Acked-by: Mark Rutland Link: https://lore.kernel.org/r/20200518091222.27467-6-sudeep.holla@arm.comSigned-off-by: Will Deacon List of files: /linux-6.15/drivers/firmware/smccc/Makefile
