Firstly it provides a convenient + * way of performing a structure-aware grep of the tree. For example it is + * possible to grep for a node and get all the properties associated with + * that node. Trees can be subsetted easily, by specifying the nodes that + * are required, and then writing out the regions returned by this function. + * This is useful for small resource-constrained systems, such as boot + * loaders, which want to use an FDT but do not need to know about all of + * it. + * + * Secondly it makes it easy to hash parts of the tree and detect changes. + * The intent is to get a list of regions which will be invariant provided + * those parts are invariant. For example, if you request a list of regions + * for all nodes but exclude the property "data", then you will get the + * same region contents regardless of any change to "data" properties. + * + * This function can be used to produce a byte-stream to send to a hashing + * function to verify that critical parts of the FDT have not changed. + * Note that semantically null changes in order could still cause false + * hash misses. Such reordering might happen if the tree is regenerated + * from source, and nodes are reordered (the bytes-stream will be emitted + * in a different order and mnay hash functions will detect this). However + * if an existing tree is modified using libfdt functions, such as + * fdt_add_subnode() and fdt_setprop(), then this problem is avoided. + * + * The nodes/properties to include/exclude are defined by a function + * provided by the caller. This function is called for each node and + * property, and must return: + * + * 0 - to exclude this part + * 1 - to include this part + * -1 - for FDT_IS_PROP only: no information is available, so include + * if its containing node is included + * + * The last case is only used to deal with properties. Often a property is + * included if its containing node is included - this is the case where + * -1 is returned.. However if the property is specifically required to be + * included/excluded, then 0 or 1 can be returned. Note that including a + * property when the FDT_REG_SUPERNODES flag is given will force its + * containing node to be included since it is not valid to have a property + * that is not in a node. + * + * Using the information provided, the inclusion of a node can be controlled + * either by a node name or its compatible string, or any other property + * that the function can determine. + * + * As an example, including node "/" means to include the root node and all + * root properties. A flag provides a way of also including supernodes (of + * which there is none for the root node), and another flag includes + * immediate subnodes, so in this case we would get the FDT_BEGIN_NODE and + * FDT_END_NODE of all subnodes of /. + * + * The subnode feature helps in a hashing situation since it prevents the + * root node from changing at all. Any change to non-excluded properties, + * names of subnodes or number of subnodes would be detected. + * + * When used with FITs this provides the ability to hash and sign parts of + * the FIT based on different configurations in the FIT. Then it is + * impossible to change anything about that configuration (include images + * attached to the configuration), but it may be possible to add new + * configurations, new images or new signatures within the existing + * framework. + * + * Adding new properties to a device tree may result in the string table + * being extended (if the new property names are different from those + * already added). This function can optionally include a region for + * the string table so that this can be part of the hash too. This is always + * the last region. + * + * The FDT also has a mem_rsvmap table which can also be included, and is + * always the first region if so. + * + * The device tree header is not included in the region list.

In the past, the C versions distributed + * by Rick Richardson (Version 1.1) and by Reinhold Weicker + * had small (though not significant) differences. + * + * 2) As far as it is possible without changes to the Dhrystone + * statistics, optimizing compilers should be prevented from + * removing significant statements. + * + * This C version has been developed in cooperation with + * Rick Richardson (Tinton Falls, NJ), it incorporates many + * ideas from the "Version 1.1" distributed previously by + * him over the UNIX network Usenet. + * I also thank Chaim Benedelac (National Semiconductor), + * David Ditzel (SUN), Earl Killian and John Mashey (MIPS), + * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley) + * for their help with comments on earlier versions of the + * benchmark. + * + * Changes: In the initialization part, this version follows mostly + * Rick Richardson's version distributed via Usenet, not the + * version distributed earlier via floppy disk by Reinhold Weicker. + * As a concession to older compilers, names have been made + * unique within the first 8 characters. + * Inside the measurement loop, this version follows the + * version previously distributed by Reinhold Weicker. + * + * At several places in the benchmark, code has been added, + * but within the measurement loop only in branches that + * are not executed. The intention is that optimizing compilers + * should be prevented from moving code out of the measurement + * loop, or from removing code altogether. Since the statements + * that are executed within the measurement loop have NOT been + * changed, the numbers defining the "Dhrystone distribution" + * (distribution of statements, operand types and locality) + * still hold. Except for sophisticated optimizing compilers, + * execution times for this version should be the same as + * for previous versions. + * + * Since it has proven difficult to subtract the time for the + * measurement loop overhead in a correct way, the loop check + * has been made a part of the benchmark. This does have + * an impact - though a very minor one - on the distribution + * statistics which have been updated for this version. + * + * All changes within the measurement loop are described + * and discussed in the companion paper "Rationale for + * Dhrystone version 2". + * + * Because of the self-imposed limitation that the order and + * distribution of the executed statements should not be + * changed, there are still cases where optimizing compilers + * may not generate code for some statements. To a certain + * degree, this is unavoidable for small synthetic benchmarks. + * Users of the benchmark are advised to check code listings + * whether code is generated for all statements of Dhrystone. + * + * Version 2.1 is identical to version 2.0 distributed via + * the UNIX network Usenet in March 1988 except that it corrects + * some minor deficiencies that were found by users of version 2.0. + * The only change within the measurement loop is that a + * non-executed "else" part was added to the "if" statement in + * Func_3, and a non-executed "else" part removed from Proc_3. + * + *************************************************************************** + * + * Defines: The following "Defines" are possible: + * -DREG=register (default: Not defined) + * As an approximation to what an average C programmer + * might do, the "register" storage class is applied + * (if enabled by -DREG=register) + * - for local variables, if they are used (dynamically) + * five or more times + * - for parameters if they are used (dynamically) + * six or more times + * Note that an optimal "register" strategy is + * compiler-dependent, and that "register" declarations + * do not necessarily lead to faster execution. + * -DNOSTRUCTASSIGN (default: Not defined) + * Define if the C compiler does not support + * assignment of structures. + * -DNOENUMS (default: Not defined) + * Define if the C compiler does not support + * enumeration types. + * -DTIMES (default) + * -DTIME + * The "times" function of UNIX (returning process times) + * or the "time" function (returning wallclock time) + * is used for measurement. + * For single user machines, "time ()" is adequate. For + * multi-user machines where you cannot get single-user + * access, use the "times ()" function. If you have + * neither, use a stopwatch in the dead of night. + * "printf"s are provided marking the points "Start Timer" + * and "Stop Timer".

It +checks the next part of the tree that it is supposed to look at +(p.nextoffset) to see if that should be included or not. When it finds +something to include, it sets info->start to its offset. This marks the +start of the region we want to include. + +Once info->start is set to the start (i.e. not -1), we continue scanning +until we find something that we don't want included. This will be the end +of a region. At this point we can close off the region and add it to the +list. So we do so, and reset info->start to -1. + +One complication here is that we want to merge regions. So when we come to +add another region later, we may in fact merge it with the previous one if +one ends where the other starts. + +The function fdt_add_region() will return -1 if it fails to add the region, +because we already have a region ready to be returned, and the new one +cannot be merged in with it. In this case, we must return the region we +found, and wait for another call to this function. When it comes, we will +repeat the processing of the tag and again try to add a region. This time it +will succeed. + +The current state of the pointers (stack, offset, etc.) is maintained in +a ptrs member. At the start of every loop iteration we make a copy of it. +The copy is then updated as the tag is processed. Only if we get to the end +of the loop iteration (and successfully call fdt_add_region() if we need +to) can we commit the changes we have made to these pointers. For example, +if we see an FDT_END_NODE tag we will decrement the depth value. But if we +need to add a region for this tag (let's say because the previous tag is +included and this FDT_END_NODE tag is not included) then we will only commit +the result if we were able to add the region. That allows us to retry again +next time. + +We keep track of a variable called 'want' which tells us what we want to +include when there is no specific information provided by the h_include +function for a particular property. This basically handles the inclusion of +properties which are pulled in by virtue of the node they are in. So if you +include a node, its properties are also included. In this case 'want' will +be WANT_NODES_AND_PROPS. The FDT_REG_DIRECT_SUBNODES feature also makes use +of 'want'. While we are inside the subnode, 'want' will be set to +WANT_NODES_ONLY, so that only the subnode's FDT_BEGIN_NODE and FDT_END_NODE +tags will be included, and properties will be skipped. If WANT_NOTHING is +selected, then we will just rely on what the h_include() function tells us. + +Using 'want' we work out 'include', which tells us whether this current tag +should be included or not. As you can imagine, if the value of 'include' +changes, that means we are on a boundary between nodes to include and nodes +to exclude. At this point we either close off a previous region and add it +to the list, or mark the start of a new region. + +Apart from the nodes, we have mem_rsvmap, the FDT_END tag and the string +list. Each of these dealt with as a whole (i.e. we create a region for each +if it is to be included). For mem_rsvmap we don't allow it to merge with +the first struct region.
