f388f60c - x86/cpu: Drop configuration options for early 64-bit CPUs

Wed, 26 Feb 2025 21:37:08 +0000

x86/cpu: Drop configuration options for early 64-bit CPUsThe x86 CPU selection menu is confusing for a number of reasons:When configuring 32-bit kernels, it shows a small number of early 64-bitmicroarchitectures (K8, Core 2) but not the regular generic 64-bit targetthat is the normal default. There is no longer a reason to run 32-bitkernels on production 64-bit systems, so only actual 32-bit CPUs needto be shown here.When configuring 64-bit kernels, the options also pointless as there isno way to pick any CPU from the past 15 years, leaving GENERIC_CPU asthe only sensible choice.Address both of the above by removing the obsolete options and makingall 64-bit kernels run on both Intel and AMD CPUs from any generation.Testing generic 32-bit kernels on 64-bit hardware remains possible,just not building a 32-bit kernel that requires a 64-bit CPU.Signed-off-by: Arnd Bergmann Signed-off-by: Ingo Molnar Cc: Linus Torvalds Link: https://lore.kernel.org/r/20250226213714.4040853-5-arnd@kernel.org List of files: /linux-6.15/drivers/misc/mei/Kconfig

d667378a - mei: rework Kconfig dependencies

Thu, 14 Dec 2023 18:39:32 +0000

mei: rework Kconfig dependenciesThe dependencies in the mei framework are inconsistent, with some symbolsusing 'select INTEL_MEI' to force it being enabled and others using'depends on INTEL_MEI'.In general, one should not select user-visible symbols, so change allof these to normal dependencies, but change the default on INTEL_MEI tobe enabled when building a kernel for an Intel CPU with ME or a genericx86 kernel.Having consistent dependencies makes the 'menuconfig' listing morereadable by using proper indentation.A large if/endif block is just a simpler syntax than repeating thedependencies for each symbol.Signed-off-by: Arnd Bergmann Reviewed-by: Wentong Wu Link: https://lore.kernel.org/r/20231214183946.109124-2-arnd@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/mei/Kconfig

mei: Add transport driver for IVSC deviceThe Intel visual sensing controller (IVSC) device is designed to controlthe camera sharing between host IPU for media usage and IVSC for contextsensing (face detection).IVSC is exposed to HOST as an SPI device and the message protocol overthe SPI BUS for communicating with the IVSC device is implemented. Thisis the backend of mei framework for IVSC device, which usually handlesthe hardware data transfer. The mei_csi and mei_ace are the clients ofIVSC mei framework.The firmware downloading for the IVSC device is implemented as well.Signed-off-by: Wentong Wu Reviewed-by: Sakari Ailus Tested-by: Hao Yao Acked-by: Tomas Winkler Link: https://lore.kernel.org/r/1701651344-20723-2-git-send-email-wentong.wu@intel.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/mei/Kconfig

264f53b4 - Revert "mei: virtio: virtualization frontend driver"

Revert "mei: virtio: virtualization frontend driver"This reverts commit d162219c655c8cf8003128a13840d6c1e183fb80.The device uses a VIRTIO device ID out of a not-for-production range.Releasing Linux using an ID out of this range will make it conflict withdevelopment setups. An official request to reserve an ID for an MEIdevice is yet to be submitted to the virtio TC, thus there's no chanceit will be reserved and fixed in time before the next release.Once requested it usually takes 2-3 weeks to land in the spec, whichmeans the device can be supported with the official ID in the next Linuxversion if contributors act quickly.Signed-off-by: Michael S.

misc/mei/hdcp: Client driver for HDCP applicationME FW contributes a vital role in HDCP2.2 authentication.HDCP2.2 driver needs to communicate to ME FW for each step of theHDCP2.2 authentication.ME FW prepare and HDCP2.2 authentication parameters and encrypt themas per spec. With such parameter Driver prepares HDCP2.2 auth messagesand communicate with HDCP2.2 sink.Similarly HDCP2.2 sink's response is shared with ME FW for decrypt andverification.Once All the steps of HDCP2.2 authentications are complete on driver'srequest ME FW will configure the port as authenticated and supply theHDCP keys to the Gen HW for encryption.Only after this stage HDCP2.2 driver can start the HDCP2.2 encryptionfor a port.ME FW is interfaced to kernel through MEI Bus Driver. To obtain theHDCP2.2 services from the ME FW through MEI Bus driver MEI ClientDriver is developed.v2: hdcp files are moved to drivers/misc/mei/hdcp/ [Tomas]v3: Squashed the Kbuild support [Tomas] UUID renamed and Module License is modified [Tomas] drv_data is set to null at remove [Tomas]v4: Module name is changed to "MEI HDCP" I915 Selects the MEI_HDCPv5: Remove redundant text from the License header Fix malformed licence Removed the drv_data resetting.v6: K-Doc addition.
