This interface is exposed -to the host as a PCI device. The Intel MEI Driver is in charge of the -communication channel between a host application and the Intel ME feature. - -Each Intel ME feature (Intel ME Client) is addressed by a GUID/UUID and -each client has its own protocol. The protocol is message-based with a -header and payload up to 512 bytes. - -Prominent usage of the Intel ME Interface is to communicate with Intel(R) -Active Management Technology (Intel AMT)implemented in firmware running on -the Intel ME. - -Intel AMT provides the ability to manage a host remotely out-of-band (OOB) -even when the operating system running on the host processor has crashed or -is in a sleep state. - -Some examples of Intel AMT usage are: - - Monitoring hardware state and platform components - - Remote power off/on (useful for green computing or overnight IT - maintenance) - - OS updates - - Storage of useful platform information such as software assets - - Built-in hardware KVM - - Selective network isolation of Ethernet and IP protocol flows based - on policies set by a remote management console - - IDE device redirection from remote management console - -Intel AMT (OOB) communication is based on SOAP (deprecated -starting with Release 6.0) over HTTP/S or WS-Management protocol over -HTTP/S that are received from a remote management console application. - -For more information about Intel AMT: -http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide - -Intel MEI Driver -======================= - -The driver exposes a misc device called /dev/mei. - -An application maintains communication with an Intel ME feature while -/dev/mei is open. The binding to a specific features is performed by calling -MEI_CONNECT_CLIENT_IOCTL, which passes the desired UUID. -The number of instances of an Intel ME feature that can be opened -at the same time depends on the Intel ME feature, but most of the -features allow only a single instance. - -The Intel AMT Host Interface (Intel AMTHI) feature supports multiple -simultaneous user applications. Therefore, the Intel MEI driver handles -this internally by maintaining request queues for the applications. - -The driver is oblivious to data that is passed between firmware feature -and host application. - -Because some of the Intel ME features can change the system -configuration, the driver by default allows only a privileged -user to access it. - -A code snippet for an application communicating with -Intel AMTHI client: - struct mei_connect_client_data data; - fd = open(MEI_DEVICE); - - data.d.in_client_uuid = AMTHI_UUID; - - ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &data); - - printf("Ver=%d, MaxLen=%ld\n", - data.d.in_client_uuid.protocol_version, - data.d.in_client_uuid.max_msg_length); - - [...] - - write(fd, amthi_req_data, amthi_req_data_len); - - [...] - - read(fd, &amthi_res_data, amthi_res_data_len); - - [...] - close(fd); - -IOCTL: -====== -The Intel MEI Driver supports the following IOCTL command: - IOCTL_MEI_CONNECT_CLIENT Connect to firmware Feature (client). - - usage: - struct mei_connect_client_data clientData; - ioctl(fd, IOCTL_MEI_CONNECT_CLIENT, &clientData); - - inputs: - mei_connect_client_data struct contain the following - input field: - - in_client_uuid - UUID of the FW Feature that needs - to connect to. - outputs: - out_client_properties - Client Properties: MTU and Protocol Version. - - error returns: - EINVAL Wrong IOCTL Number - ENODEV Device or Connection is not initialized or ready. - (e.g. Wrong UUID) - ENOMEM Unable to allocate memory to client internal data. - EFAULT Fatal Error (e.g. Unable to access user input data) - EBUSY Connection Already Open - - Notes: - max_msg_length (MTU) in client properties describes the maximum - data that can be sent or received.

This means that some Intel AMT features can be accessed from a - local application using the same network interface as a remote application - communicating with Intel AMT over the network. - - When a local application sends a message addressed to the local Intel AMT host - name, the Intel LMS, which listens for traffic directed to the host name, - intercepts the message and routes it to the Intel MEI. - For more information: - http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide - Under "About Intel AMT" => "Local Access" - - For downloading Intel LMS: - http://software.intel.com/en-us/articles/download-the-latest-intel-amt-open-source-drivers/ - - The Intel LMS opens a connection using the Intel MEI driver to the Intel LMS - firmware feature using a defined UUID and then communicates with the feature - using a protocol called Intel AMT Port Forwarding Protocol(Intel APF protocol). - The protocol is used to maintain multiple sessions with Intel AMT from a - single application. - - See the protocol specification in the Intel AMT Software Development Kit(SDK) - http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide - Under "SDK Resources" => "Intel(R) vPro(TM) Gateway(MPS)" - => "Information for Intel(R) vPro(TM) Gateway Developers" - => "Description of the Intel AMT Port Forwarding (APF)Protocol" - - 2) Intel AMT Remote configuration using a Local Agent - A Local Agent enables IT personnel to configure Intel AMT out-of-the-box - without requiring installing additional data to enable setup.

This is -achieved via a call to the following function: - - int vme_register_driver (struct vme_driver *driver); - -If driver registration is successful this function returns zero, if an error -occurred a negative error code will be returned. - -A pointer to a structure of type 'vme_driver' must be provided to the -registration function. The structure is as follows: - - struct vme_driver { - struct list_head node; - const char *name; - int (*match)(struct vme_dev *); - int (*probe)(struct vme_dev *); - int (*remove)(struct vme_dev *); - void (*shutdown)(void); - struct device_driver driver; - struct list_head devices; - unsigned int ndev; - }; - -At the minimum, the '.name', '.match' and '.probe' elements of this structure -should be correctly set. The '.name' element is a pointer to a string holding -the device driver's name. - -The '.match' function allows controlling the number of devices that need to -be registered. The match function should return 1 if a device should be -probed and 0 otherwise. This example match function (from vme_user.c) limits -the number of devices probed to one: - - #define USER_BUS_MAX 1 - ... - static int vme_user_match(struct vme_dev *vdev) - { - if (vdev->id.num >= USER_BUS_MAX) - return 0; - return 1; - } - -The '.probe' element should contain a pointer to the probe routine. The -probe routine is passed a 'struct vme_dev' pointer as an argument. The -'struct vme_dev' structure looks like the following: - - struct vme_dev { - int num; - struct vme_bridge *bridge; - struct device dev; - struct list_head drv_list; - struct list_head bridge_list; - }; - -Here, the 'num' field refers to the sequential device ID for this specific -driver. The bridge number (or bus number) can be accessed using -dev->bridge->num. - -A function is also provided to unregister the driver from the VME core and is -usually called from the device driver's exit routine: - - void vme_unregister_driver (struct vme_driver *driver); - - -Resource management -=================== - -Once a driver has registered with the VME core the provided match routine will -be called the number of times specified during the registration. If a match -succeeds, a non-zero value should be returned. A zero return value indicates -failure. For all successful matches, the probe routine of the corresponding -driver is called. The probe routine is passed a pointer to the devices -device structure. This pointer should be saved, it will be required for -requesting VME resources. - -The driver can request ownership of one or more master windows, slave windows -and/or dma channels. Rather than allowing the device driver to request a -specific window or DMA channel (which may be used by a different driver) this -driver allows a resource to be assigned based on the required attributes of the -driver in question: - - struct vme_resource * vme_master_request(struct vme_dev *dev, - u32 aspace, u32 cycle, u32 width); - - struct vme_resource * vme_slave_request(struct vme_dev *dev, u32 aspace, - u32 cycle); - - struct vme_resource *vme_dma_request(struct vme_dev *dev, u32 route); - -For slave windows these attributes are split into the VME address spaces that -need to be accessed in 'aspace' and VME bus cycle types required in 'cycle'. -Master windows add a further set of attributes in 'width' specifying the -required data transfer widths. These attributes are defined as bitmasks and as -such any combination of the attributes can be requested for a single window, -the core will assign a window that meets the requirements, returning a pointer -of type vme_resource that should be used to identify the allocated resource -when it is used. For DMA controllers, the request function requires the -potential direction of any transfers to be provided in the route attributes. -This is typically VME-to-MEM and/or MEM-to-VME, though some hardware can -support VME-to-VME and MEM-to-MEM transfers as well as test pattern generation. -If an unallocated window fitting the requirements can not be found a NULL -pointer will be returned. - -Functions are also provided to free window allocations once they are no longer -required.

This function returns the original value of the -VME bus location : - - unsigned int vme_master_rmw (struct vme_resource *res, - unsigned int mask, unsigned int compare, unsigned int swap, - loff_t offset); - -This functions by reading the offset, applying the mask. If the bits selected in -the mask match with the values of the corresponding bits in the compare field, -the value of swap is written the specified offset. - - -Slave windows -============= - -Slave windows provide devices on the VME bus access into mapped portions of the -local memory. The number of windows available and the access modes that can be -used is dependent on the underlying chipset. A window must be configured before -it can be used. - - -Slave window configuration --------------------------- - -Once a slave window has been assigned the following functions can be used to -configure it and retrieve the current settings: - - int vme_slave_set (struct vme_resource *res, int enabled, - unsigned long long base, unsigned long long size, - dma_addr_t mem, u32 aspace, u32 cycle); - - int vme_slave_get (struct vme_resource *res, int *enabled, - unsigned long long *base, unsigned long long *size, - dma_addr_t *mem, u32 *aspace, u32 *cycle); - -The address spaces, transfer widths and cycle types are the same as described -under resource management, however some of the options are mutually exclusive. -For example, only one address space may be specified. - -These functions return 0 on success or an error code should the call fail. - - -Slave window buffer allocation ------------------------------- - -Functions are provided to allow the user to allocate and free a contiguous -buffers which will be accessible by the VME bridge.

The -API introduces the concept of DMA lists. Each DMA list is a link-list which can -be passed to a DMA controller. Multiple lists can be created, extended, -executed, reused and destroyed. - - -List Management ---------------- - -The following functions are provided to create and destroy DMA lists. Execution -of a list will not automatically destroy the list, thus enabling a list to be -reused for repetitive tasks: - - struct vme_dma_list *vme_new_dma_list(struct vme_resource *res); - - int vme_dma_list_free(struct vme_dma_list *list); - - -List Population ---------------- - -An item can be added to a list using the following function ( the source and -destination attributes need to be created before calling this function, this is -covered under "Transfer Attributes"): - - int vme_dma_list_add(struct vme_dma_list *list, - struct vme_dma_attr *src, struct vme_dma_attr *dest, - size_t count); - -NOTE: The detailed attributes of the transfers source and destination - are not checked until an entry is added to a DMA list, the request - for a DMA channel purely checks the directions in which the - controller is expected to transfer data. As a result it is - possible for this call to return an error, for example if the - source or destination is in an unsupported VME address space. - -Transfer Attributes -------------------- - -The attributes for the source and destination are handled separately from adding -an item to a list. This is due to the diverse attributes required for each type -of source and destination. There are functions to create attributes for PCI, VME -and pattern sources and destinations (where appropriate): - -Pattern source: - - struct vme_dma_attr *vme_dma_pattern_attribute(u32 pattern, u32 type); - -PCI source or destination: - - struct vme_dma_attr *vme_dma_pci_attribute(dma_addr_t mem); - -VME source or destination: - - struct vme_dma_attr *vme_dma_vme_attribute(unsigned long long base, - u32 aspace, u32 cycle, u32 width); - -The following function should be used to free an attribute: - - void vme_dma_free_attribute(struct vme_dma_attr *attr); - - -List Execution --------------- - -The following function queues a list for execution. The function will return -once the list has been executed: - - int vme_dma_list_exec(struct vme_dma_list *list); - - -Interrupts -========== - -The VME API provides functions to attach and detach callbacks to specific VME -level and status ID combinations and for the generation of VME interrupts with -specific VME level and status IDs. - - -Attaching Interrupt Handlers ----------------------------- - -The following functions can be used to attach and free a specific VME level and -status ID combination.

The following function can be used to determine how many locations -are provided: - - int vme_lm_count(struct vme_resource * res); - - -Location Monitor Configuration ------------------------------- - -Once a bank of location monitors has been allocated, the following functions -are provided to configure the location and mode of the location monitor: - - int vme_lm_set(struct vme_resource *res, unsigned long long base, - u32 aspace, u32 cycle); - - int vme_lm_get(struct vme_resource *res, unsigned long long *base, - u32 *aspace, u32 *cycle); - - -Location Monitor Use --------------------- - -The following functions allow a callback to be attached and detached from each -location monitor location. Each location monitor can monitor a number of -adjacent locations: - - int vme_lm_attach(struct vme_resource *res, int num, - void (*callback)(int)); - - int vme_lm_detach(struct vme_resource *res, int num); - -The callback function is declared as follows. - - void callback(int num); - - -Slot Detection -============== - -This function returns the slot ID of the provided bridge. - - int vme_slot_get(struct vme_dev *dev);
