153/* Descriptions of variables used by the build process:
154
155   The following variables are lists available to all makefiles:
156     DESTDIR              Root of the ts directory in the build tree.
157     CDEBUGFLAGS          Passed to all compiles of code that goes in mmfsd
158                            or other process-level code.  Empty by default;
159                            intended to be used temporarily within the
160                            Imakefile in a directory to turn on generation of
161                            assembly listings, say.
162     KCDEBUGFLAGS         Passed to all compiles of code that goes in kernel
163                            extensions.  Empty by default.
164     OPTFLAGS             Compiler optimization flags for daemon code and
165                            code that is compiled once and bound into both
166                            the daemon and the kernel.  Typical values are -g
167                            or -O.
168     KOPTFLAGS            Compiler optimization flags for code used exclusively
169                            in kernel modules.
170     ARCH_DEFINES         -D defines describing the machine architecture
171     DEFAULT_DEFINES      List of -D defines used for shipped product code.
172                            The complete list of possible -D values is given
173                            below.
174     TEMPSHIP_DEFINES     List of -D defines used for debuging, not shipped
175                            in product code after first few PTFs of new release.
176     NEVERSHIP_DEFINES    List of -D defines used for testing, never shipped
177                            in product code.
178     SITE_DEFINES         List of the complete set of -D defines used by each
179                            compilation in the build.  For testing, this will
180                            be the concatenation of DEFAULT_DEFINES,
181                            ARCH_DEFINES, TEMPSHIP_DEFINES, and
182                            NEVERSHIP_DEFINES.  For the shipped product,
183                            this will just contain DEFAULT_DEFINES and
184                            ARCH_DEFINES (and TEMPSHIP_DEFINES for a
185                            little while).
186
187     KERNEL_HEADER_DIR    Directory where Linux kernel header files are kept
188
189   The following variables are either defined or undefined by this file.
190   Tests of these are used in Imakefiles to conditionally control which
191   lines are processed.  For almost all of these there is a
192   corresponding -Dxxx that must be specified in SITE_DEFINES.
193
194     DMAPI                #define this to cause code implementing the DMAPI
195                            interface to GPFS to be built.  Requires -DDMAPI
196                            in SITE_DEFINES.
197     FAR_TRACE            #define this to cause calls to the routine that
198                            actually does TRACEn to be placed far away from
199                            the tests of whether tracing is enabled.  When
200                            tracing is off, this results in fewer I-cache
201                            misses, and therefore better performance.  Also
202                            controls several compiler options that are needed
203                            to get the correct code generated.  Cannot be
204                            used with -g.
205     LINUX_KERNEL_VERSION  #define this to match the version of the Linux
206                            include files being used for the applicable
207                            architecture type.  This is always an eight
208                            digit decimal number.  The first four
209                            digits give the major and minor kernel version
210                            numbers.  For Linux 2.4 these will always be
211                            0204, with the leading zero omitted.  The next
212                            two digits give the kernel subversion.  The last
213                            two digits give the patch level.  Thus the
214                            LINUX_KERNEL_VERSION of
215                              linux-2.4.18-14 is 2041814
216                            while
217                              linux-2.4.19    is 2041900
218
219                            The compile-time symbol LINUX_KERNEL_VERSION
220                            will be set to the same value as the make-time
221                            symbol LINUX_KERNEL_VERSION. 
222                            The GPFS_KERNEL_VERSION macro uses the same
223                            encoding of kernel version as does
224                            LINUX_KERNEL_VERSION, and can be used to
225                            conditionally compile version dependent code.
226     GPROF_DAEMON         #define this to compile and link the daemon for
227                            gprof.  Use 'mmfsadm test gprof on|off' to control
228                            when profiling is enabled.  (Not tested in years,
229                            may not work.)
230     TRY_AND_BUY          #define this to build a "try and buy" version of
231                            GPFS with a timeout license key
232     MMPMON               #define this to build support for MMPMON remote
233                            performance monitoring services.  Requires -DMMPMON
234                            in SITE_DEFINES.
235     MMPMON_CUMULATIVE    #define this to build support for MMPMON remote
236                            performance monitoring cumulative all-time stats.
237          Requires -DMMPMON in SITE_DEFINES.
238     MMPMON_HISTOGRAMS    #define this to build support for MMPMON remote
239                            performance monitoring latency histogram data.
240          Requires -DMMPMON *and* -DMMPMON_HISTOGRAMS
241                            in SITE_DEFINES.
242     EXPORTER_EVENTS      #define this to enable the APPEND_EXPORTER_EVENT code
243          originally used by the Java GUI
244     SMB_LOCKS            #define this to add SMB share mode and oplock support
245                            Requires -DSMB_LOCKS in SITE_DEFINES
246     CCL                  #define this to add support for CIFS Compatibility
247                           Layer.  Requires -DCCL in SITE_DEFINES
248     KTRACE               #define this to build trace device into Linux
249                            kernel and allow trace statements in kernel.
250                            Requires -DKTRACE in SITE_DEFINES
251     NO_ASM_UTIL          #define this to prevent the use of assembler versions
252                            of utility routines in classes/basic directory
253     CROSS_COMPILE        #define this when cross-compiling to avoid running
254                            tools that must be built for the target system but
255                            run on the build system (e.g. chksystypes program)
256     POLICY               #define this to compile the policy library. Use with
257                      -DPOOLS and -DPOLICY
258     NOKREGPARMS          #define this to build gpfs compatable for a
259          custom built 2.6 kernel with CONFIG_REGPARMS
260          turned off.
261
262   Descriptions of all -Dxxx values that control building GPFS features.
263   To generate optional code add one or more of the following to
264   SITE_DEFINES:
265
266   Standard system features
267     -D__FULL_PROTO       Used by AIX header files to ensure that prototypes
268                          of functions include full parameter list.  Needed
269                          since these functions have a C calling convention and
270                          thus must always be defined with their full proto.
271     -DBLOCK_RESTORE      Add support for block level incremental
272                      backup & restore.
273     -DDIO                Direct I/O support
274     -DDIO_XW             Define this to allow direct I/O writes to
275                            allocate new data blocks rather than falling
276                            back to normal I/O, provided that write request
277                            is block-aligned block multiple.  DIO will use
278                            xw byte-range lock rather than whole-file sx
279                            lock for block-sized I/O.
280     -DDISK_LEASE_DMS     Add support for a deadman switch.  When disk leasing
281                            is on, a kernel timer will be turned on, to be
282                            restarted whenever a new lease is obtained.  If
283                            the lease cannot be renewed, and timer expires,
284                            and there's still some outstanding I/O requests,
285                            the node is paniced.
286     -DDMAPI              Activate DMAPI code (also define DMAPI).
287     -DDMAPI_MOVERS       Activate DMAPI parallel movers code.
288     -DDMAPI_PREFETCH_DIRATTRS Active parallel dm_get_dirattr and dm_get_dmattr
289     -DLC_FENCING         Enable LC fencing of VSD disks
290     -DMMAP_DIO           Change mmap page-out to use direct I/O to write
291                            the page if a GPFS data buffer is not available.
292                            This removes the requirement that read/write
293                            mapped pages always have a GPFS data buffer to
294                            back them.  Requires -DDIO.
295     -DNFS_SKIP_SHRINK_TO_FIT Don't do shrink to fit for NFS when the open
296                            file is not empty.
297     -DPOW2_COND_SHIFT    Enable code that implements multiplies and divides
298                            by shifts when possible.
299     -DSANERGY            Enable SANergy interfaces.
300     -DSFS_PERF_SKIP_SYNC Performance improvement to skip multiple sync calls
301                            for the same file.
302     -DSFS_PERF_USE_SMALL_BUFFER try to use small buffers to avoid reading
303                            data that might not be referenced.
304     -DSMB_LOCKS          Add support for SMB open locks and oplocks.
305     -DSPAIXLVL=432       AIX level. Must use this option when compiling on
306                            AIX 4.3.2 (with new compiler).
307     -DSPAIXLVL=433       Must use this option when compiling on AIX 4.3.3

309     -DMMPMON             Enable MMPMON performance monitoring
310       (also enable -DMMPMON.)
311     -DMMPMON_CUMULATIVE  Enable MMPMON performance monitoring cumulative
312        all time stats (also enable -DMMPMON and
313        define MMPMON)
314     -DMMPMON_DAEMON_PORT Enable code that allows mmpmon/EE connections via
315                           the standard daemon port.  Authentication done by
316                           llcomm.  Compatible with MMPMON_NAMED_SOCKET.
317     -DMMPMON_HISTOGRAMS  Enable MMPMON performance monitoring latency
318        histograms (also enable -DMMPMON and
319        define MMPMON + MMPMON_HISTOGRAMS.)
320     -DMMPMON_NAMED_SOCKET Enable MMPMON named socket instead of the
321                           independent EE network port.  Mutually exclusive.
322     -DMMPMON_RPC         Enable MMPMON rpc interface
323     -DEXPORTER_EVENTS    Enable the APPEND_EXPORTER_EVENT code
324          originally used by the Java GUI
325     -DFAR_TRACE          LINUX: Generate calls to the TRACE subroutine
326                            out-of-line with respect to the tests of whether
327                            tracing is enabled.  Do not explicitly include
328                            this in the list of -D options; it will be
329                            provided automatically if FAR_TRACE or
330                            KFAR_TRACE is #defined.
331     -DFAR_CODE           LINUX: Enable the BEGIN_FAR_CODE/END_FAR_CODE macros
332                            to place arbitrary uncommonly executed code
333                            out-of-line.  Requires -DFAR_TRACE.  Do not
334                            explicitly include this in the list of -D
335                            options; it will be provided automatically
336                            if FAR_TRACE or KFAR_TRACE is #defined.
337     -DUSE51BREGS         AIX: Use AIX 5.1.B register semantics in assembler
338                          code.  Must be turned on for code that will
339                          run on AIX 5.x.
340     -DTSCOMM_SECURITY    Enable support for secure network communication.
341     -DLIMIT_KSTACKS      Generate code that is less efficient in the GPFS
342                            kernel module, but that uses less kernel stack
343                            space.  Needed on i386 for Linux kernel versions
344                            at or beyond 2.6.6.
345     -DPERF_STATS         Additional performance statistics for benchmark runs
346
347   Defines for new upcoming features:
348     -DCCL                Add support for CIFS Compatibility Layer.
349     -DEE_WATCHDOG_START  Start the EE watchdog thread (checks for anomolies)
350                          This feature used to be enabled, but since there
351                          is currently no consumer for its data, it is now
352                          disabled by default.
353     -DNFS4_CLUSTER       Add support for NFS Version 4.
354                            Requires the 2.4.18 nfsv4 kernel.
355     -DNFS4_ACL           Add support for NFSv4 ACLs.
356     -DNFS4_VCM           Add support for the AIX VCM (NFSv4 locking)
357
358     -DDESCQUORUM_OVERRIDE Add support for manual overrides of the stripe
359                             group descriptor quorum.
360     -DUIDREMAP           Enable support for UID remapping in multicluster
361                          environment.
362     -DALLOC_SUM_FILE     Enable support allocation summary file
363
364     -DCHECK_KXTIMESTAMP  Enable code that a) links both mmfsd and mmfs with
365                          an object that contains a timestamp b) checks very
366                          early during daemon startup that kernel and userspace
367                          code have the same timestamp, i.e. the kernel
368                          extension loaded in memory is from the same build as
369                          the currently starting daemon.  The intent is to
370                          prevent hard-to-diagnose problems arising (on AIX,
371                          most often) from having a stale kernel extension
372                          loaded after installing a new build.  Will only be
373                          enabled in ADE/ODE builds, although CVS builders
374                          can enable it as well.
375     -DPOOLS              Add support for multiple disk storage pools.
376     -DFILESETS           Add support for filesets.
377     -DFILESET_QUOTAS     Add support for fileset quotas. Must be used with
378                          FILESETS.
379     -DPOLICY             Policy language and commands - used with POOLS and FILESETS, prereq
380     -DPOLICY_RESTORE       Initial support for new RESTORE policy attributes
381     -DPOLICY_RESTORE_RULES Add support for new RESTORE policy rules
382     -DSINGLE_PORT        Enable support for use of a single port number.
383     -DTHREADED_RECEIVER  Enables multi-threaded receiver code.
384     -DNO_XCLUST          Avoid sending cross-cluster RPCs between different
385                          remote clusters
386     -DWAIT_FOR_NSD_SERVERS Enables the feature to wait for NSD servers to
387                          come up on mounts, when cluster is first formed,
388                          and other select situations (see doc for details.)
389
390   Defines for non GA versions of the code but turned on for our web
391   based "try and buy" version of GPFS.
392     -DTRY_AND_BUY        Build a "try and buy" version of
393                            GPFS with a timeout license key
394
395   Defines for Normal testing, not for shipped systems:
396     -DDBGASSERTS         Generate code for DBGASSERT macros
397     -DTRIGGERS           Respond to 'test trigger xxx' commands
398     -DTRACK_USECOUNT     Code to track contributing threads to a stripe
399                            group's use count.
400     -DDIRCHECKASSERTS    Check validity of directory disk data structures
401                            frequently, and assert when an inconsistency is
402                            found.  Expensive, so separated from DBGASSERTS.
403     -DPTHREAD_STATS      Generate code to count how many times various
404                            paths are taken through thread, mutex, and
405                            condition variable code.
406     -DNO_ASM_SYNCH       Disable implementation of fast versions of mutex
407                            acquire/release in assembler.  Enables trace
408                            calls and some debugging code under -DDBGASSERTS
409                            that is not supported by the assembler
410                            implementation.  Required if -DTRACK_RESOURCE_USAGE
411                            is used.
412     -DINSTRUMENT_LOCKS   Enable summary lock instrumentation for mutexes
413                            and lock objects.  Requires -DPTHREAD_STATS.
414     -DINSTRUMENT_DETAIL_LOCKS
415                          Also enable per-mutex lock instrumentation.
416                            Requires -DINSTRUMENT_LOCKS.
417     -DTM_DETAIL_STATS    Extra counters to track which token prefetches
418                            are useful and which are not.
419     -DVERBOSETRACE       Generate code to produce traces for trace levels > 10
420     -DGPFS_FRAME_POINTER Tell GPFS code that -fomit-frame-pointer was not
421                           specified, so frame pointer is available. Use
422                           either -fomit-frame-pointer or -DGPFS_FRAME_POINTER
423                           when defining OPTFLAGS
424     -DENTRYEXIT_TRACE    Enable routine entry/exit tracing that is controlled
425                           by mmfsadm trace entryexit <n>
426     -DKSTACK_CHECK       Keep track of how much kernel stack space is used
427                           within GPFS kernel modules.  Print tracebacks of
428                           the point of maximum stack usage if it exceeds a
429                           threshhold.  Can only be used on Linux.
430
431   Defines for weird test conditions, not normally used:
432     -DPOW2_FORCE_SHIFT   Do only shifts for some math. Requires that all
433                          GPFS block sizes be power of 2.
434                          Since VTS uses 384K blocksize, this is not a
435                          shipable option.
436     -DTIME_MUTEXES       Time how long mutexes are held.  Summary produced
437                            by 'mmfsadm dump lstat'. 
438                            Requires -DINSTRUMENT_LOCKS.
439     -DGPFS_PRINTF        On Linux, send trace output to the console via printk
440                            instead of collecting trace output using ltrace.
441                            (requires GPFS_LINUX).
442     -DTSCAN              Enable trace points used by the tscan utility to
443                            measure CPU usage by system call.
444     -DTRACK_RESOURCE_USAGE
445                          Keep track of resources (locks, mutexes, buffers,
446                            threads, etc.) held by a thread and verify that
447                            resources are acquired in a consistent order.
448                            Requires -DNO_ASM_SYNCH.
449     -DSUPPORT_FOR_DOS_STATFS  Hack for DOS client fsstat
450     -DDACSPY             Counts the number of times objects of each of
451                            the dynamic array classes are created.
452                            The classes are defined via the DECL_ARRAY_CLASS
453                            macro in DAC.h.  This optional instrumentation
454                            allows for determining which objects being
455                            allocated on the heap may require allocation
456                            optimization such as via a linked list of
457                            preallocated objects.
458     -DMALLOC_DEBUG       Generate code to track the file and line number from
459                            which each block of MALLOCed storage was allocated
460     -DTRACE_IO_DATA      If RTPERF trace level is >= 3, dump the first few
461                            words of data read or written by any disk I/O
462                            operation.  This is a security exposure, and should
463                            not be turned on in production.
464     -DNEW_DELETE_DEBUG   Override global operators new and delete, to assist
465                            in finding uninitialized dynamic storage, writing
466                            beyond the end of an allocated object, reference to
467                            deleted objects, and storage leaks.  The 'mmfsadm
468                            test newdebug' command enables some of these
469                            features.
470     -DNEW_DELETE_TRACEBACKS
471                          Save the call stack on memory allocations tracked
472                            by -DNEW_DELETE_DEBUG.  Not supported on Linux.
473     -DDIR_VERSION_NUMBERS
474                          Increment one of the reserved words in directory
475                            block headers each time the block is written to
476                            disk.  Helps to sequence directory updates in time
477                            across multiple nodes.  Should never be turned on
478                            except on file systems that will be reformatted.
479     -DTEST_SMALL_DISKS=x When creating a file system or adding disks,
480                            artificially limit the disk size to x megabytes.
481                            Useful for testing ENOSPC conditions without having
482                            to fill up large disks or creating new, smaller
483                            logical volumes.
484     -DTEST_DELDISK       Ignore all but the first disk listed in mount
485                            options.  This is useful when testing so that
486                            the tsdeldisk and tsrpldisk commands can be used
487                            without the "mm" commands.
488     -DNO_VFS_STATS       Do not generate any code to generate statistics for
489                            the 'mmfsadm vfsstats {enable|disable|reset|show}'
490                            family of commands.
491     -DSTOP_TRACE_ON_FAILURE Set all trace flags to 0 as soon as LOGASSERT
492                            is triggered or deamon cleanup begins.
493     -DDEBUG_SPINLOCK     Define this if Linux kernel is built with
494                            CONFIG_DEBUG_SPINLOCK.
495     -DFILEIDCMD_PERF     Define this to enable perf measurements for mmfileid
496                            command
497     -DKTRACE             Define this to build trace device into Linux
498                            kernel and allow trace statements in kernel
499                            (also define KTRACE).
500     -DENABLE_SKIP_DATA_MOVE Enable the 'mmfsadm test disableDataXfer 0/1'
501                            command to skip moving data between user buffers
502                            and GPFS buffers and to skip data I/O.  Allows
503                            simulating a higher metadata load than the actual
504                            data I/O configuration would support.
