+ * When the asynchronous task has finished preparing the model, it must immediately invoke the

+ * prepareModelFromCache is used to retrieve a prepared model directly from cache files to avoid

+ * driver: model cache and data cache. For more information on the two types of cache files,
+ * refer to getNumberOfCacheFilesNeeded.
+ *
+ * The file descriptors must be opened with read and write permission. A file may have any size,
+ * and the corresponding file descriptor may have any offset. The driver must truncate a file to
+ * zero size before writing to that file. The file descriptors may be closed by the client once
+ * the asynchronous preparation has finished. The driver must dup a file descriptor if it wants
+ * to get access to the cache file later.
+ *
+ * The model is prepared asynchronously with respect to the caller. The prepareModelFromCache
+ * function must verify the inputs to the prepareModelFromCache function are correct, and that
+ * the security-sensitive cache has not been modified since it was last written by the driver.
+ * If there is an error, or if compilation caching is not supported, or if the
+ * security-sensitive cache has been modified, prepareModelFromCache must immediately invoke the
+ * callback with the appropriate ErrorStatus value and nullptr for the IPreparedModel, then
+ * return a status with a service specific exception with the same ErrorStatus. If the inputs to
+ * the prepareModelFromCache function are valid, the security-sensitive cache is not modified,
+ * and there is no error, prepareModelFromCache must launch an asynchronous task to prepare the
+ * model in the background, and immediately return from prepareModelFromCache. If the
+ * asynchronous task fails to launch, prepareModelFromCache must immediately invoke the callback
+ * with ErrorStatus::GENERAL_FAILURE and nullptr for the IPreparedModel, then return a service
+ * specific exception with ErrorStatus::GENERAL_FAILURE.
+ *
+ * When the asynchronous task has finished preparing the model, it must immediately invoke the
+ * callback function provided as an input to prepareModelFromCache. If the model was prepared
+ * successfully, the callback object must be invoked with an error status of ErrorStatus::NONE
+ * and the produced IPreparedModel object. If an error occurred preparing the model, the
+ * callback object must be invoked with the appropriate ErrorStatus value and nullptr for the
+ * IPreparedModel.
+ *
+ * prepareModelFromCache can be called with an optional deadline. If the model is not able to
+ * prepared before the provided deadline, the model preparation may be aborted, and either

+ * It processes the incoming input using a 2-stage filtering mechanism:

+ * get pushed into a memory of fixed-size memory_size.
+ * * stage 2 performs filtering on the "time" dimension of the memory_size
+ * memoized outputs of stage 1.
+ *
+ * Specifically, for rank 1, this layer implements the operation:
+ *
+ * memory = push(conv1d(inputs, weights_feature, feature_dim,

+ * outputs = activation(memory * weights_time + bias);

+ * Where:

+ * convolving the input with every “feature filter”), and whose outputs
+ * get pushed, stacked in order, into the fixed-size “memory” (the oldest
+ * entry gets dropped);
+ * * “weights_time” is a weights matrix that processes the “memory” (by a
+ * batched matrix multiplication on the num_units);
+ * * “bias” is an optional bias vector (added to each output vector in the
+ * batch); and

+ * The inputs to this operation are the condition subgraph, the body subgraph,
+ * and operand values for the first iteration of the loop. The values are
+ * implicitly split into three groups of input-output, state-only, and
+ * input-only values, as described below.
+ *
+ * The outputs of this operation are the final values of input-output
+ * operands.
+ *
+ * Both the condition and body subgraph receive (m + k + n) inputs.
+ * * The first m (m >= 1) inputs are input-output operands. For the first
+ * iteration, these are initialized from the corresponding inputs of the
+ * WHILE operation. In subsequent iterations, their values come from the
+ * corresponding outputs of the body subgraph produced during the previous
+ * iteration.
+ * * The next k (k >= 0) inputs are state-only operands. They are similar to
+ * the input-output operands, except that their values are no longer
+ * available after the loop terminates.
+ * * The last n (n >= 0) inputs are input-only operands. Their values come
+ * from the corresponding inputs of the WHILE operation.
+ *
+ * The body subgraph produces (m + k) outputs.
+ * * The first m outputs are input-output operands. They become the outputs
+ * of the WHILE operation when a termination condition is reached.
+ * * The last k outputs are state-only operands. Their values are no longer
+ * available after the loop terminates.
+ *
+ * The numbers m, k, and n are inferred by the driver as follows:
+ * m = (WHILE operation output count)
+ * k = (body subgraph output count) - m
+ * n = (body subgraph input count) - m - k

+ * Some countries or carriers require some emergency numbers that must be handled with normal
+ * call routing if possible or emergency routing. 1) if the 'routing' field is specified as
+ * @1.4::EmergencyNumberRouting#NORMAL, the implementation must try the full radio service to

+ * If the dialed emergency number does not have a specified emergency service category, the

+ * does not support the emergency service category or emergency uniform resource names, the
+ * field 'categories' or 'urns' may be ignored.
+ *
+ * In the scenarios that the 'address' in the 'dialInfo' field has other functions besides the
+ * emergency number function, if the 'hasKnownUserIntentEmergency' field is true, the user's

+/**
+ * An IRemotelyProvisionedComponent is a secure-side component for which certificates can be
+ * remotely provisioned. It provides an interface for generating asymmetric key pairs and then
+ * creating a CertificateRequest that contains the generated public keys, plus other information to
+ * authenticate the request origin. The CertificateRequest can be sent to a server, which can
+ * validate the request and create certificates.
+ *
+ * This interface does not provide any way to use the generated and certified key pairs. It's
+ * intended to be implemented by a HAL service that does other things with keys (e.g. Keymint).
+ *
+ * The root of trust for secure provisioning is something called the "Boot Certificate Chain", or
+ * BCC. The BCC is a chain of public key certificates, represented as COSE_Sign1 objects containing
+ * COSE_Key representations of the public keys. The "root" of the BCC is a self-signed certificate
+ * for a device-unique public key, denoted DK_pub. All public keys in the BCC are device-unique. The
+ * public key from each certificate in the chain is used to sign the next certificate in the
+ * chain. The final, "leaf" certificate contains a public key, denoted KM_pub, whose corresponding
+ * private key, denoted KM_priv, is available for use by the IRemotelyProvisionedComponent.
+ *
+ * BCC Design
+ * ==========
+ *
+ * The BCC is designed to mirror the boot stages of a device, and to prove the content and integrity
+ * of each firmware image. In a proper BCC, each boot stage hashes its own private key with the code
+ * and any relevant configuration parameters of the next stage to produce a key pair for the next
+ * stage. Each stage also uses its own private key to sign the public key of the next stage,
+ * including in the certificate the hash of the next firmware stage, then loads the next stage,
+ * passing the private key and certificate to it in a manner that does not leak the private key to
+ * later boot stages. The BCC root key pair is generated by immutable code (e.g. ROM), from a
+ * device-unique secret. After the device-unique secret is used, it must be made unavailable to any
+ * later boot stage.
+ *
+ * In this way, booting the device incrementally builds a certificate chain that (a) identifies and
+ * validates the integrity of every stage and (b) contains a set of public keys that correspond to
+ * private keys, one known to each stage. Any stage can compute the secrets of all later stages
+ * (given the necessary input), but no stage can compute the secret of any preceding stage. Updating
+ * the firmware or configuration of any stage changes the key pair of that stage, and of all
+ * subsequent stages, and no attacker who compromised the previous version of the updated firmware
+ * can know or predict the post-update key pairs.
+ *
+ * The first BCC certificate is special because its contained public key, DK_pub, will never change,
+ * making it a permanent, device-unique identifier. Although the remaining keys in the BCC are also
+ * device-unique, they are not necessarily permanent, since they can change when the device software
+ * is updated.
+ *
+ * When the provisioning server receives a message signed by KM_priv and containing a BCC that
+ * chains from DK_pub to KM_pub, it can be certain that (barring vulnerabilities in some boot
+ * stage), the CertificateRequest came from the device associated with DK_pub, running the specific
+ * software identified by the certificates in the BCC. If the server has some mechanism for knowing
+ * which the DK_pub values of "valid" devices, it can determine whether signing certificates is
+ * appropriate.
+ *
+ * Degenerate BCCs
+ * ===============
+ *
+ * While a proper BCC, as described above, reflects the complete boot sequence from boot ROM to the
+ * secure area image of the IRemotelyProvisionedComponent, it's also possible to use a "degenerate"
+ * BCC which consists only of a single, self-signed certificate containing the public key of a
+ * hardware-bound key pair. This is an appopriate solution for devices which haven't implemented
+ * everything necessary to produce a proper BCC, but can derive a unique key pair in the secure
+ * area. In this degenerate case, DK_pub is the same as KM_pub.
+ *
+ * BCC Privacy
+ * ===========
+ *
+ * Because the BCC constitutes an unspoofable, device-unique identifier, special care is taken to
+ * prevent its availability to entities who may wish to track devices. Two precautions are taken:
+ *
+ * 1. The BCC is never exported from the IRemotelyProvisionedComponent except in encrypted
+ * form. The portion of the CertificateRequest that contains the BCC is encrypted using an
+ * Endpoint Encryption Key (EEK). The EEK is provided in the form of a certificate chain whose
+ * root must be pre-provisioned into the secure area (hardcoding the roots into the secure area
+ * firmware image is a recommended approach). Multiple roots may be provisioned. If the provided
+ * EEK does not chain back to this already-known root, the IRemotelyProvisionedComponent must
+ * reject it.
+ *
+ * 2. Precaution 1 above ensures that only an entity with a valid EEK private key can decrypt the
+ * BCC. To make it feasible to build a provisioning server which cannot use the BCC to track
+ * devices, the CertificateRequest is structured so that the server can be partitioned into two
+ * components. The "decrypter" decrypts the BCC, verifies DK_pub and the device's right to
+ * receive provisioned certificates, but does not see the public keys to be signed or the
+ * resulting certificates. The "certifier" gets informed of the results of the decrypter's
+ * validation and sees the public keys to be signed and resulting certificates, but does not see
+ * the BCC.
+ *
+ * Test Mode
+ * =========
+ *
+ * The IRemotelyProvisionedComponent supports a test mode, allowing the generation of test key pairs
+ * and test CertificateRequests. Test keys/requests are annotated as such, and the BCC used for test
+ * CertificateRequests must contain freshly-generated keys, not the real BCC key pairs.

+# KeyMint Benchmark
+
+The KeyMint Benchmark is a standalone tool for measuring the performance of
+ KeyMint implementations.
+
+## Building
+
+Build:
+`m VtsAidlKeyMintBenchmarkTest`
+
+Transfer to device/emulator:
+`adb sync data`
+
+The benchmark executable will be located at
+ `data/benchmarktest/VtsAidlKeyMintBenchmarkTest` on the device.
+
+## Usage
+
+KeyMint Benchmark is built on [Google microbenchmark
+library](https://github.com/google/benchmark). All of the commandline arguments
+provided by the microbenchmark library are valid, such as
+`--benchmark_filter=<regex>` or `benchmark_out_format={json|console|csv}`.
+In addition to the command line arguments provided by microbenchmark,
+`--service_name=<service_name>` is provided to allow specification of the KeyMint
+fully qualified service name, e.g. specify
+`--service_name=android.hardware.security.keymint.IKeyMintDevice/default` to
+benchmark default implementation of KeyMint.
