Move net/iob to drivers/iob so that the I/O buffering feature can be available to other drivers when networking is disabled.

Merged in antmerlino/nuttx/iobinstrumentation (pull request #1001) Iobinstrumentation * mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources. * iob instrumentation - Merges producer/consumer enumeration for simpler IOB user. * fs/procfs: Starts adding support for /proc/iobinfo * fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry Approved-by: Gregory Nutt <gnutt@nuttx.org>

mm/iob: Add an IOB notifier that will send a signal to any registered threads that want to be notified when an IOB has been freed. This is an untested work-in-progress and is intended to be a part of a larger solution to correctly handling network poll operations.
2018-09-09 01:21:18 +08:00
ifeq ($(CONFIG_IOB_NOTIFIER),y)
sched/signal: Add a generic signal notification facility. Modify the custom IOB available notifier so that it is now just a wrapper around this generic signal notification. This generic signal notification faility will, eventually, be used to support network polling. Squashed commit of the following: mm/iob: The IOB available notifier is now just a wrapper around the common signal notifier. sched/signal: Add a generic signal notification facility. sched/signal/sig_evthread.c: More trivial naming changes. sched/signal: Rename nxsig_notification() to nxsig_evthread() to make forthcoming naming additions more consistent.

Revert "Makefile: move INCDIROPT to common place (#625)" This reverts commit b9ace36fcc7ccb55d1541231be07689d557628f4. This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk: else ifeq ($(WINTOOL),y) DEFINE = "$(TOPDIR)/tools/define.sh" INCDIR = "$(TOPDIR)/tools/incdir.sh" -w This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
