  "message": "PCI/TSM: Add \u0027dsm\u0027 and \u0027bound\u0027 attributes for dependent functions\n\nPCI/TSM sysfs for physical function 0 devices, i.e. the \"DSM\" (Device\nSecurity Manager), contains the \u0027connect\u0027 and \u0027disconnect\u0027 attributes.\nAfter a successful \u0027connect\u0027 operation the DSM, its dependent functions\n(SR-IOV virtual functions, non-zero multi-functions, or downstream\nendpoints of a switch DSM) are candidates for being transitioned into a\nTDISP (TEE Device Interface Security Protocol) operational state, via\npci_tsm_bind(). At present sysfs is blind to which devices are capable of\nTDISP operation and it is ambiguous which functions are serviced by which\nDSMs.\n\nAdd a \u0027dsm\u0027 attribute to identify a function\u0027s DSM device, and add a\n\u0027bound\u0027 attribute to identify when a function has entered a TDISP\noperational state.\n\nCc: Bjorn Helgaas \u003cbhelgaas@google.com\u003e\nCc: Lukas Wunner \u003clukas@wunner.de\u003e\nCc: Samuel Ortiz \u003csameo@rivosinc.com\u003e\nCc: Alexey Kardashevskiy \u003caik@amd.com\u003e\nCc: Xu Yilun \u003cyilun.xu@linux.intel.com\u003e\nCc: Suzuki K Poulose \u003csuzuki.poulose@arm.com\u003e\nCc: Aneesh Kumar K.V \u003caneesh.kumar@kernel.org\u003e\nReviewed-by: Jonathan Cameron \u003cjonathan.cameron@huawei.com\u003e\nLink: https://patch.msgid.link/20251113021446.436830-9-dan.j.williams@intel.com\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\n",
