SPDX-License-Identifier: GPL-2.0 + +======================================= +The padata parallel execution mechanism +======================================= + +:Date: December 2019 + +Padata is a mechanism by which the kernel can farm jobs out to be done in +parallel on multiple CPUs while retaining their ordering. It was developed for +use with the IPsec code, which needs to be able to perform encryption and +decryption on large numbers of packets without reordering those packets. The +crypto developers made a point of writing padata in a sufficiently general +fashion that it could be put to other uses as well. + +Usage +===== + +Initializing +------------ + +The first step in using padata is to set up a padata_instance structure for +overall control of how jobs are to be run:: + + #include <linux/padata.h> + + struct padata_instance *padata_alloc_possible(const char *name); + +'name' simply identifies the instance. + +There are functions for enabling and disabling the instance:: + + int padata_start(struct padata_instance *pinst); + void padata_stop(struct padata_instance *pinst); + +These functions are setting or clearing the "PADATA_INIT" flag; if that flag is +not set, other functions will refuse to work. padata_start() returns zero on +success (flag set) or -EINVAL if the padata cpumask contains no active CPU +(flag not set). padata_stop() clears the flag and blocks until the padata +instance is unused. + +Finally, complete padata initialization by allocating a padata_shell:: + + struct padata_shell *padata_alloc_shell(struct padata_instance *pinst); + +A padata_shell is used to submit a job to padata and allows a series of such +jobs to be serialized independently. A padata_instance may have one or more +padata_shells associated with it, each allowing a separate series of jobs. + +Modifying cpumasks +------------------ + +The CPUs used to run jobs can be changed in two ways, programatically with +padata_set_cpumask() or via sysfs. The former is defined:: + + int padata_set_cpumask(struct padata_instance *pinst, int cpumask_type, + cpumask_var_t cpumask); + +Here cpumask_type is one of PADATA_CPU_PARALLEL or PADATA_CPU_SERIAL, where a +parallel cpumask describes which processors will be used to execute jobs +submitted to this instance in parallel and a serial cpumask defines which +processors are allowed to be used as the serialization callback processor. +cpumask specifies the new cpumask to use. + +There may be sysfs files for an instance's cpumasks. For example, pcrypt's +live in /sys/kernel/pcrypt/<instance-name>. Within an instance's directory +there are two files, parallel_cpumask and serial_cpumask, and either cpumask +may be changed by echoing a bitmask into the file, for example:: + + echo f > /sys/kernel/pcrypt/pencrypt/parallel_cpumask + +Reading one of these files shows the user-supplied cpumask, which may be +different from the 'usable' cpumask. + +Padata maintains two pairs of cpumasks internally, the user-supplied cpumasks +and the 'usable' cpumasks. (Each pair consists of a parallel and a serial +cpumask.) The user-supplied cpumasks default to all possible CPUs on instance +allocation and may be changed as above. The usable cpumasks are always a +subset of the user-supplied cpumasks and contain only the online CPUs in the +user-supplied masks; these are the cpumasks padata actually uses. So it is +legal to supply a cpumask to padata that contains offline CPUs. Once an +offline CPU in the user-supplied cpumask comes online, padata is going to use +it. + +Changing the CPU masks are expensive operations, so it should not be done with +great frequency. + +Running A Job +------------- + +Actually submitting work to the padata instance requires the creation of a +padata_priv structure, which represents one job:: + + struct padata_priv { + /* Other stuff here... */ + void (*parallel)(struct padata_priv *padata); + void (*serial)(struct padata_priv *padata); + }; + +This structure will almost certainly be embedded within some larger +structure specific to the work to be done. Most of its fields are private to +padata, but the structure should be zeroed at initialisation time, and the +parallel() and serial() functions should be provided. Those functions will +be called in the process of getting the work done as we will see +momentarily. + +The submission of the job is done with:: + + int padata_do_parallel(struct padata_shell *ps, + struct padata_priv *padata, int *cb_cpu); + +The ps and padata structures must be set up as described above; cb_cpu +points to the preferred CPU to be used for the final callback when the job is +done; it must be in the current instance's CPU mask (if not the cb_cpu pointer +is updated to point to the CPU actually chosen). The return value from +padata_do_parallel() is zero on success, indicating that the job is in +progress. -EBUSY means that somebody, somewhere else is messing with the +instance's CPU mask, while -EINVAL is a complaint about cb_cpu not being in the +serial cpumask, no online CPUs in the parallel or serial cpumasks, or a stopped +instance. + +Each job submitted to padata_do_parallel() will, in turn, be passed to +exactly one call to the above-mentioned parallel() function, on one CPU, so +true parallelism is achieved by submitting multiple jobs. parallel() runs with +software interrupts disabled and thus cannot sleep. The parallel() +function gets the padata_priv structure pointer as its lone parameter; +information about the actual work to be done is probably obtained by using +container_of() to find the enclosing structure. + +Note that parallel() has no return value; the padata subsystem assumes that +parallel() will take responsibility for the job from this point. The job +need not be completed during this call, but, if parallel() leaves work +outstanding, it should be prepared to be called again with a new job before +the previous one completes. + +Serializing Jobs +---------------- + +When a job does complete, parallel() (or whatever function actually finishes +the work) should inform padata of the fact with a call to:: + + void padata_do_serial(struct padata_priv *padata); + +At some point in the future, padata_do_serial() will trigger a call to the +serial() function in the padata_priv structure. That call will happen on +the CPU requested in the initial call to padata_do_parallel(); it, too, is +run with local software interrupts disabled. +Note that this call may be deferred for a while since the padata code takes +pains to ensure that jobs are completed in the order in which they were +submitted. + +Destroying +---------- + +Cleaning up a padata instance predictably involves calling the three free +functions that correspond to the allocation in reverse:: + + void padata_free_shell(struct padata_shell *ps); + void padata_stop(struct padata_instance *pinst); + void padata_free(struct padata_instance *pinst); + +It is the user's responsibility to ensure all outstanding jobs are complete +before any of the above are called. + +Interface +========= + +.. kernel-doc:: include/linux/padata.h +.. kernel-doc:: kernel/padata.c diff --git a/Documentation/crypto/devel-algos.rst b/Documentation/crypto/devel-algos.rst index f9d288015acc..f225a953ab4b 100644 --- a/Documentation/crypto/devel-algos.rst +++ b/Documentation/crypto/devel-algos.rst @@ -31,33 +31,23 @@ The counterparts to those functions are listed below. :: - int crypto_unregister_alg(struct crypto_alg *alg); - int crypto_unregister_algs(struct crypto_alg *algs, int count); + void crypto_unregister_alg(struct crypto_alg *alg); + void crypto_unregister_algs(struct crypto_alg *algs, int count); -Notice that both registration and unregistration functions do return a -value, so make sure to handle errors.
