Mon, 04 Dec 2017 16:57:28 +0000

crypto: ccp: Add Platform Security Processor (PSP) device supportThe Platform Security Processor (PSP) is part of the AMD SecureProcessor (AMD-SP) functionality. The PSP is a dedicated processorthat provides support for key management commands in Secure EncryptedVirtualization (SEV) mode, along with software-based Trusted ExecutionEnvironment (TEE) to enable third-party trusted applications.Note that the key management functionality provided by the SEV firmwarecan be used outside of the kvm-amd driver hence it doesn't need todepend on CONFIG_KVM_AMD.Cc: Paolo Bonzini Cc: "Radim Krčmář" Cc: Borislav Petkov Cc: Herbert Xu Cc: Gary Hook Cc: Tom Lendacky Cc: linux-crypto@vger.kernel.orgCc: kvm@vger.kernel.orgCc: linux-kernel@vger.kernel.orgImprovements-by: Borislav Petkov Signed-off-by: Brijesh Singh Reviewed-by: Borislav Petkov List of files: /linux-6.15/drivers/crypto/ccp/Kconfig

596103cf - crypto: drivers - Fix Kconfig selects

Wed, 17 Jun 2015 06:58:24 +0000

crypto: drivers - Fix Kconfig selectsThis patch fixes a number of problems in crypto driver Kconfigentries:1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internaland should not be used outside of the crypto API itself.2. Do not select ALGAPI unless you use a legacy type likeCRYPTO_ALG_TYPE_CIPHER.3. Select the algorithm type that you are implementing, e.g., AEAD.4. Do not select generic C code such as CBC/ECB unless you use themas a fallback.5. Remove default n since that is the default default.Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/ccp/Kconfig

126ae9ad - crypto: ccp - Base AXI DMA cache settings on device tree

Thu, 10 Jul 2014 15:58:35 +0000

crypto: ccp - Base AXI DMA cache settings on device treeThe default cache operations for ARM64 were changed during 3.15.To use coherent operations a "dma-coherent" device tree propertyis required. If that property is not present in the device treenode then the non-coherent operations are assigned for the device.Add support to the ccp driver to assign the AXI DMA cache settingsbased on whether the "dma-coherent" property is present in the devicenode. If present, use settings that work with the caches. If notpresent, use settings that do not look at the caches.Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/ccp/Kconfig
