Constants
D3D11_CONTENT_PROTECTION_CAPS_SOFTWAREValue: 0x1 The content protection is implemented in software by the driver. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWAREValue: 0x2 The content protection is implemented in hardware by the GPU. |
D3D11_CONTENT_PROTECTION_CAPS_PROTECTION_ALWAYS_ONValue: 0x4 Content protection is always applied to a protected surface, regardless of whether the application explicitly enables protection. |
D3D11_CONTENT_PROTECTION_CAPS_PARTIAL_DECRYPTIONValue: 0x8 The driver can use partially encrypted buffers. If this capability is not present, the entire buffer must be either encrypted or clear. |
D3D11_CONTENT_PROTECTION_CAPS_CONTENT_KEYValue: 0x10 The driver can encrypt data using a separate content key that is encrypted using the session key. |
D3D11_CONTENT_PROTECTION_CAPS_FRESHEN_SESSION_KEYValue: 0x20 The driver can refresh the session key without renegotiating the key. |
D3D11_CONTENT_PROTECTION_CAPS_ENCRYPTED_READ_BACKValue: 0x40 The driver can read back encrypted data from a protected surface. For more information, see ID3D11VideoContext::EncryptionBlt. |
D3D11_CONTENT_PROTECTION_CAPS_ENCRYPTED_READ_BACK_KEYValue: 0x80 The driver requires a separate key to read encrypted data from a protected surface. |
D3D11_CONTENT_PROTECTION_CAPS_SEQUENTIAL_CTR_IVValue: 0x100 If the encryption type is D3DCRYPTOTYPE_AES128_CTR, the application must use a sequential count in the D3D11_AES_CTR_IV structure. |
D3D11_CONTENT_PROTECTION_CAPS_ENCRYPT_SLICEDATA_ONLYValue: 0x200 The driver supports encrypted slice data, but does not support any other encrypted data in the compressed buffer. The caller should not encrypt any data within the buffer other than the slice data. Note The driver should only report this flag for the specific profiles that have this limitation. |
D3D11_CONTENT_PROTECTION_CAPS_DECRYPTION_BLTValue: 0x400 The driver can copy encrypted data from one resource to another, decrypting the data as part of the process. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWARE_PROTECT_UNCOMPRESSEDValue: 0x800 The hardware supports the protection of specific resources. This means that:
Note This enumeration value is supported starting with Windows 10. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWARE_PROTECTED_MEMORY_PAGEABLEValue: 0x1000 Physical pages of a protected resource can be evicted and potentially paged to disk in low memory conditions without losing the contents of the resource when paged back in. Note This enumeration value is supported starting with Windows 10. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWARE_TEARDOWNValue: 0x2000 The hardware supports an automatic teardown mechanism that could trigger hardware keys or protected content to become lost in some conditions. The application can register to be notified when these events occur. Note This enumeration value is supported starting with Windows 10. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWARE_DRM_COMMUNICATIONValue: 0x4000 The secure environment is tightly coupled with the GPU and an ID3D11CryptoSession should be used for communication between the user mode DRM component and the secure execution environment. Note This enumeration value is supported starting with Windows 10. |
D3D11_CONTENT_PROTECTION_CAPS_HARDWARE_DRM_COMMUNICATION_MULTI_THREADEDValue: 0x8000 |
