From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- drivers/crypto/ccp/Kconfig | 56 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 drivers/crypto/ccp/Kconfig (limited to 'drivers/crypto/ccp/Kconfig') diff --git a/drivers/crypto/ccp/Kconfig b/drivers/crypto/ccp/Kconfig new file mode 100644 index 000000000..f16a0f611 --- /dev/null +++ b/drivers/crypto/ccp/Kconfig @@ -0,0 +1,56 @@ +# SPDX-License-Identifier: GPL-2.0-only +config CRYPTO_DEV_CCP_DD + tristate "Secure Processor device driver" + depends on CPU_SUP_AMD || ARM64 + default m + help + Provides AMD Secure Processor device driver. + If you choose 'M' here, this module will be called ccp. + +config CRYPTO_DEV_SP_CCP + bool "Cryptographic Coprocessor device" + default y + depends on CRYPTO_DEV_CCP_DD && DMADEVICES + select HW_RANDOM + select DMA_ENGINE + select CRYPTO_SHA1 + select CRYPTO_SHA256 + help + Provides the support for AMD Cryptographic Coprocessor (CCP) device + which can be used to offload encryption operations such as SHA, AES + and more. + +config CRYPTO_DEV_CCP_CRYPTO + tristate "Encryption and hashing offload support" + default m + depends on CRYPTO_DEV_CCP_DD + depends on CRYPTO_DEV_SP_CCP + select CRYPTO_HASH + select CRYPTO_SKCIPHER + select CRYPTO_AUTHENC + select CRYPTO_RSA + select CRYPTO_LIB_AES + help + Support for using the cryptographic API with the AMD Cryptographic + Coprocessor.
