With USE_POLL poll() is called with at # least one pollfd per I/O-blocked thread, so 1000 threads sharing one # descriptor will poll 1000 identical pollfds and select would be more # efficient. But if the threads all use different descriptors poll() # may be better depending on your operating system's implementation of # poll and select. Really, it's up to you. Oh, and on some platforms # poll() fails with more than a few dozen descriptors. # # Some platforms allow to define FD_SETSIZE (if select() is used), e.g.: # DEFINES += -DFD_SETSIZE=4096 # # To use malloc(3) instead of mmap(2) for stack allocation: # DEFINES += -DMALLOC_STACK # # To provision more than the default 16 thread-specific-data keys # (but not too many!): # DEFINES += -DST_KEYS_MAX= # # To start with more than the default 64 initial pollfd slots # (but the table grows dynamically anyway): # DEFINES += -DST_MIN_POLLFDS_SIZE= # # Note that you can also add these defines by specifying them as # make/gmake arguments (without editing this Makefile). For example: # # make EXTRA_CFLAGS=-DUSE_POLL # # (replace make with gmake if needed). # # You can also modify the default selection of an alternative event # notification mechanism. E.g., to enable kqueue(2) support (if it's not # enabled by default): # # gmake EXTRA_CFLAGS=-DMD_HAVE_KQUEUE # # or to disable default epoll(4) support: # # make EXTRA_CFLAGS=-UMD_HAVE_EPOLL # ########################## CFLAGS += $(DEFINES) $(OTHER_FLAGS) $(EXTRA_CFLAGS) OBJS = $(TARGETDIR)/sched.o \ $(TARGETDIR)/stk.o \ $(TARGETDIR)/sync.o \ $(TARGETDIR)/key.o \ $(TARGETDIR)/io.o \ $(TARGETDIR)/event.o \ $(TARGETDIR)/srs.o OBJS += $(EXTRA_OBJS) SRS = $(TARGETDIR)/srs linux-debug: all all: $(TARGETDIR) $(SRS) $(TARGETDIR): if [ ! -d $(TARGETDIR) ]; then mkdir $(TARGETDIR); fi $(SRS): $(OBJS) $(CC) $(CFLAGS) -o $@ $(OBJS) $(TARGETDIR)/md.o: md.S $(CC) $(CFLAGS) -c $< -o $@ $(TARGETDIR)/%.o: %.c common.h md.h $(CC) $(CFLAGS) -c $< -o $@ clean: rm -rf $(TARGETDIR)
