	152
	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
	308	-DSPAIXLVL=516 Must use this option when compiling on AIX 5.1.6+
	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.
