documentation: Moved devtool workflow to sdk manual
Fixes [YOCTO #11630] The section on the devtool workflow in the dev-manual was 99% identical to what was in the sdk-manual. I have moved the workflow procedure from the old "Model" chapter of the dev-manual to be merged with what was in the sdk-manual. In truth, the only things added were a note about devtool not being exclusive to SDK development. The result of moving (deleting) this section was that the "model" chapter of the dev-manual went away. The devtool stuff, Quilt, devshell, and python shell are all out now and there is no chapter left. So, mega-manual had to be adjusted to not pull that chapter in when building the dev-manual. I had to delete three figures that were used in the flow. The figures were already replicated in the sdk-manual. The figures were deleted from the figures folder of both the dev-manual and the mega-manual. I had to make sure all references to the old devtool stuf in the YP doc set were adjusted.

48 A common development workflow consists of modifying project source
49 files that are external to the Yocto Project and then integrating
50 that project's build output into an image built using the
51 OpenEmbedded build system.
52 Given this scenario, development engineers typically want to stick
53 to their familiar project development tools and methods, which allows
54 them to just focus on the project.

122 The <filename>devtool add</filename> command generates

124 This command takes advantage of the

126 layer that many <filename>devtool</filename> commands
127 use.
128 The command is flexible enough to allow you to extract source

149 The top part of the flow shows three scenarios by which
150 you could use <filename>devtool add</filename> to
151 generate a recipe based on existing source code.</para>
152
153 <para>In a shared development environment, it is
154 typical where other developers are responsible for
155 various areas of source code.
156 As a developer, you are probably interested in using
157 that source code as part of your development using
158 the Yocto Project.
159 All you need is access to the code, a recipe, and a
160 controlled area in which to do your work.</para>
161
162 <para>Within the diagram, three possible scenarios
163 feed into the <filename>devtool add</filename> workflow:
164 <itemizedlist>
165 <listitem><para><emphasis>Left</emphasis>:
166 The left scenario represents a common situation
167 where the source code does not exist locally
168 and needs to be extracted.
169 In this situation, you just let it get
170 extracted to the default workspace - you do not
171 want it in some specific location outside of the
172 workspace.
173 Thus, everything you need will be located in the
174 workspace:
175 <literallayout class='monospaced'>
176 $ devtool add <replaceable>recipe fetchuri</replaceable>
177 </literallayout>
178 With this command, <filename>devtool</filename>
179 creates a recipe and an append file in the
180 workspace as well as extracts the upstream
181 source files into a local Git repository also
182 within the <filename>sources</filename> folder.
183 </para></listitem>
184 <listitem><para><emphasis>Middle</emphasis>:
185 The middle scenario also represents a situation where
186 the source code does not exist locally.
187 In this case, the code is again upstream
188 and needs to be extracted to some
189 local area - this time outside of the default
190 workspace.
191 If required, <filename>devtool</filename>
192 always creates
193 a Git repository locally during the extraction.
194 Furthermore, the first positional argument
195 <replaceable>srctree</replaceable> in this case
196 identifies where the
197 <filename>devtool add</filename> command
198 will locate the extracted code outside of the
199 workspace:
200 <literallayout class='monospaced'>
201 $ devtool add <replaceable>recipe srctree fetchuri</replaceable>
202 </literallayout>
203 In summary, the source code is pulled from
204 <replaceable>fetchuri</replaceable> and extracted
205 into the location defined by
206 <replaceable>srctree</replaceable> as a local
207 Git repository.</para>
208
209 <para>Within workspace, <filename>devtool</filename>
210 creates both the recipe and an append file
211 for the recipe.
212 </para></listitem>
213 <listitem><para><emphasis>Right</emphasis>:
214 The right scenario represents a situation
215 where the source tree (srctree) has been
216 previously prepared outside of the
217 <filename>devtool</filename> workspace.
218 </para>
219
220 <para>The following command names the recipe
221 and identifies where the existing source tree
222 is located:
223 <literallayout class='monospaced'>
224 $ devtool add <replaceable>recipe srctree</replaceable>
225 </literallayout>
226 The command examines the source code and creates
227 a recipe for it placing the recipe into the
228 workspace.</para>
229
230 <para>Because the extracted source code already exists,
231 <filename>devtool</filename> does not try to
232 relocate it into the workspace - just the new
233 the recipe is placed in the workspace.</para>
234
235 <para>Aside from a recipe folder, the command
236 also creates an append folder and places an initial
237 <filename>*.bbappend</filename> within.

240 </para></listitem>
241 <listitem><para><emphasis>Edit the Recipe</emphasis>:
242 At this point, you can use <filename>devtool edit-recipe</filename>
243 to open up the editor as defined by the
244 <filename>$EDITOR</filename> environment variable
245 and modify the file:
246 <literallayout class='monospaced'>
247 $ devtool edit-recipe <replaceable>recipe</replaceable>

262 <para>On the other hand, if you want an image to
263 contain the recipe's packages for immediate deployment
264 onto a device (e.g. for testing purposes), you can use
265 the <filename>devtool build-image</filename> command:

269 </para></listitem>
270 <listitem><para><emphasis>Deploy the Build Output</emphasis>:
271 When you use the <filename>devtool build</filename>
272 command to build out your recipe, you probably want to
273 see if the resulting build output works as expected on target
274 hardware.
275 <note>
276 This step assumes you have a previously built
277 image that is already either running in QEMU or
278 running on actual hardware.
279 Also, it is assumed that for deployment of the image
280 to the target, SSH is installed in the image and if
281 the image is running on real hardware that you have
282 network access to and from your development machine.
283 </note>
284 You can deploy your build output to that target hardware by
285 using the <filename>devtool deploy-target</filename> command:
286 <literallayout class='monospaced'>
287 $ devtool deploy-target <replaceable>recipe target</replaceable>
288 </literallayout>
289 The <replaceable>target</replaceable> is a live target machine

291
292 <para>You can, of course, also deploy the image you build
293 using the <filename>devtool build-image</filename> command
294 to actual hardware.

296 specific command that allows you to do this.

299 <emphasis>Finish Your Work With the Recipe</emphasis>:
300 The <filename>devtool finish</filename> command creates
301 any patches corresponding to commits in the local
302 Git repository, moves the new recipe to a more permanent
303 layer, and then resets the recipe so that the recipe is
304 built normally rather than from the workspace.
305 <literallayout class='monospaced'>
306 $ devtool finish <replaceable>recipe layer</replaceable>

309 Any changes you want to turn into patches must be

312
313 <para>As mentioned, the <filename>devtool finish</filename>
314 command moves the final recipe to its permanent layer.

316
317 <para>As a final process of the
318 <filename>devtool finish</filename> command, the state
319 of the standard layers and the upstream source is
320 restored so that you can build the recipe from those
321 areas rather than the workspace.
322 <note>
323 You can use the <filename>devtool reset</filename>
324 command to put things back should you decide you
325 do not want to proceed with your work.
326 If you do use this command, realize that the source

338 The <filename>devtool modify</filename> command prepares the

344 associated with the code.

377 created some layer for use with the Yocto Project and
378 their recipe already resides in that layer.
379 Furthermore, their source code is readily available
380 either upstream or locally.
381 <itemizedlist>
382 <listitem><para><emphasis>Left</emphasis>:
383 The left scenario represents a common situation
384 where the source code does not exist locally
385 and needs to be extracted.
386 In this situation, the source is extracted
387 into the default workspace location.
388 The recipe, in this scenario, is in its own
389 layer outside the workspace
390 (i.e.
391 <filename>meta-</filename><replaceable>layername</replaceable>).
392 </para>
393
394 <para>The following command identifies the recipe
395 and by default extracts the source files:
396 <literallayout class='monospaced'>
397 $ devtool modify <replaceable>recipe</replaceable>
398 </literallayout>
399 Once <filename>devtool</filename>locates the recipe,
400 it uses the
401 <ulink url='&YOCTO_DOCS_REF_URL;#var-SRC_URI'><filename>SRC_URI</filename></ulink>
402 variable to locate the source code and
403 any local patch files from other developers are
404 located.
405 <note>
406 You cannot provide an URL for
407 <replaceable>srctree</replaceable> when using the
408 <filename>devtool modify</filename> command.
409 </note>
410 With this scenario, however, since no
411 <replaceable>srctree</replaceable> argument exists, the
412 <filename>devtool modify</filename> command by default
413 extracts the source files to a Git structure.
414 Furthermore, the location for the extracted source is the
415 default area within the workspace.
416 The result is that the command sets up both the source
417 code and an append file within the workspace with the
418 recipe remaining in its original location.
419 </para></listitem>
420 <listitem><para><emphasis>Middle</emphasis>:
421 The middle scenario represents a situation where
422 the source code also does not exist locally.
423 In this case, the code is again upstream
424 and needs to be extracted to some
425 local area as a Git repository.
426 The recipe, in this scenario, is again in its own
427 layer outside the workspace.</para>
428
429 <para>The following command tells
430 <filename>devtool</filename> what recipe with
431 which to work and, in this case, identifies a local
432 area for the extracted source files that is outside
433 of the default workspace:
434 <literallayout class='monospaced'>
435 $ devtool modify <replaceable>recipe srctree</replaceable>
436 </literallayout>
437 As with all extractions, the command uses
438 the recipe's <filename>SRC_URI</filename> to locate the
439 source files.
440 Once the files are located, the command by default
441 extracts them.
442 Providing the <replaceable>srctree</replaceable>
443 argument instructs <filename>devtool</filename> where
444 to place the extracted source.</para>
445
446 <para>Within workspace, <filename>devtool</filename>
447 creates an append file for the recipe.
448 The recipe remains in its original location but
449 the source files are extracted to the location you
450 provided with <replaceable>srctree</replaceable>.
451 </para></listitem>
452 <listitem><para><emphasis>Right</emphasis>:
453 The right scenario represents a situation
454 where the source tree
455 (<replaceable>srctree</replaceable>) exists as a
456 previously extracted Git structure outside of
457 the <filename>devtool</filename> workspace.
458 In this example, the recipe also exists

563 <para>
564 The <filename>devtool upgrade</filename> command updates
565 an existing recipe so that you can build it for an updated
566 set of source files.
567 The command is flexible enough to allow you to specify
568 source code revision and versioning schemes, extract code into

570 work with any source file forms that the fetchers support.

585 <listitem><para><emphasis>Initiate the Upgrade</emphasis>:
586 The top part of the flow shows a typical scenario by which
587 you could use <filename>devtool upgrade</filename>.
588 The following conditions exist:
589 <itemizedlist>
590 <listitem><para>The recipe exists in some layer external
591 to the <filename>devtool</filename> workspace.
592 </para></listitem>
593 <listitem><para>The source files for the new release
594 exist adjacent to the same location pointed to by
595 <ulink url='&YOCTO_DOCS_REF_URL;#var-SRC_URI'><filename>SRC_URI</filename></ulink>
596 in the recipe (e.g. a tarball with the new version
597 number in the name, or as a different revision in
598 the upstream Git repository).
599 </para></listitem>
600 </itemizedlist>
601 A common situation is where third-party software has
602 undergone a revision so that it has been upgraded.
603 The recipe you have access to is likely in your own layer.
604 Thus, you need to upgrade the recipe to use the
605 newer version of the software:
606 <literallayout class='monospaced'>
607 $ devtool upgrade -V <replaceable>version recipe</replaceable>
608 </literallayout>
609 By default, the <filename>devtool upgrade</filename> command
610 extracts source code into the <filename>sources</filename>
611 directory in the workspace.
612 If you want the code extracted to any other location, you
613 need to provide the <replaceable>srctree</replaceable>
614 positional argument with the command as follows:
615 <literallayout class='monospaced'>
616 $ devtool upgrade -V <replaceable>version recipe srctree</replaceable>
617 </literallayout>
618 Also, in this example, the "-V" option is used to specify
619 the new version.
620 If the source files pointed to by the
621 <filename>SRC_URI</filename> statement in the recipe are
622 in a Git repository, you must provide the "-S" option and
623 specify a revision for the software.</para>
624
625 <para>Once <filename>devtool</filename> locates the recipe,
626 it uses the <filename>SRC_URI</filename> variable to locate
627 the source code and any local patch files from other
628 developers are located.
629 The result is that the command sets up the source
630 code, the new version of the recipe, and an append file
631 all within the workspace.
632 </para></listitem>
633 <listitem><para><emphasis>Resolve any Conflicts created by the Upgrade</emphasis>:
634 At this point, there could be some conflicts due to the
635 software being upgraded to a new version.
636 This would occur if your recipe specifies some patch files in
637 <filename>SRC_URI</filename> that conflict with changes
638 made in the new version of the software.
639 If this is the case, you need to resolve the conflicts
640 by editing the source and following the normal
641 <filename>git rebase</filename> conflict resolution
642 process.</para>
643
644 <para>Before moving onto the next step, be sure to resolve any
645 such conflicts created through use of a newer or different
646 version of the software.
647 </para></listitem>
648 <listitem><para><emphasis>Build the Recipe</emphasis>:
649 Once you have your recipe in order, you can build it.
650 You can either use <filename>devtool build</filename> or
651 <filename>bitbake</filename>.
652 Either method produces build output that is stored
