  the MBX use it.

  additional support package for developing USB-ethernet and similar

  peripherals.

* Added POSIX cancellation points for the sigwait family of functions,

  pthread_join, pthread_cond_wait, pthread_cond_timedwait, sleep and

  nanosleep

* Virtual vectors initialization can now be configured with a finer

  granularity. Diagnostic output should also appear on the same channel

  (possibly ethernet) as the application was launched from.

* Added cyg_pci_find_matching() to PCI library API to allow more generalized

  matching on device properties.

* ARM EBSA285 now configured to use virtual vectors all the time. Users with

  old GDB stub ROM images should upgrade to newer GDB stub ROM images, or

  better still to RedBoot.

* Stack usage measurement has been added, with the functions

  pthread_measure_stack_usage() in the POSIX thread API and

  cyg_thread_measure_stack_usage() in the kernel C API.

* Thread stack checking support added. See CYGFUN_KERNEL_THREADS_STACK_CHECKING

  in the kernel CDL for information.

* Add syscall support to RedBoot for compatibility with newlib-based BSPs

  platform. This includes serial device driver and wallclock device driver

  support.

* Port to Intel SA1100 Multimedia evalulation board added, including serial

  device driver, FLASH driver and RedBoot support

* FLASH driver added for PowerPC/MBX

* sigsetjmp() and siglongjmp() added

* A choice of getcwd() implementations have been added

* SH serial driver cleanup. SCIF driver added. SCI and SCIF drivers are

  now separate packages. SCIF driver uses full FIFO and can utilize

  DMA for transmit operations.

* Move logical ethernet "driver" into io/eth where the interface can be shared

  between multiple implementations, e.g. BSD TCP/IP and Red Boot's TCP/IP

  stacks.

* RedBoot - the Red Hat Bootstrap ROM monitor has been added, initially

  supporting ARM-EDB7xxx, ARM-EBSA285, and ARM-Assabet boards. Provides

  serial and ethernet GDB debugging support, flash image management and flash

  booting, BOOTP/DHCP and TFTP boot support and a CLI interface.

* Added PCMCIA and Compact Flash support, including drivers for the ARM-Assabet

  board.

* Added generic FLASH memory support

* Added flash memory support for ARM-EBSA285 and ARM-EDB7xxx boards

* Added Compact Flash Ethernet driver

* Hitachi SH7707a variant support added.

* Support added for both software and hardware flow control with an initial

  version of the latter available only for the ARM PID board at present.

* Loopback serial device driver added

* POSIX termios support added for EL/IX level 1 compatibility

* Improved dynamic memory management support in the memory allocator

  package. Existing dynamic memory support in the kernel (fixed and variable

  block allocators) and in libc (malloc, etc.) has been moved to this

  package, located at services/memalloc/common. It is now possible to support

  memory pools occupying all of remaining memory (as determined by the MLT).

  New memory allocators can be "plugged in", and an example of Doug Lea's

  malloc (dlmalloc) has been included.

* Plug-in filesystem support added, with a POSIX 1003.1 compatible API, found

  in the io/fileio package, and integrated with the C library.

* An initial example filesystem implementation is provided in fs/ram. This

  is a RAM filesystem that attempts to both be a useful tool in its own

  right and an example of how to write a filesystem that plugs into the

  fileio infrastructure.

  The source of the filesystem is in fs/ram/VERSION/src/ramfs.c and is

  intended to be largely self documenting. The General Description at

  the beginning of the file gives an overview of the structure of the

  system, and comments within the code explain specific points. This

  code should be read in conjunction with the description of the fileio

  infrastructure.

* Support added for POSIX 1003.1 threads, mutexes, semaphores, message queues,

  condition variables, clocks, timers and real-time signals in the POSIX

  compatibility package (part of the EL/IX compatibility initiative) found at

  compat/posix.

* Kernel enhanced with Asynchronous Service Routines (ASRs) which are routines

  called back at the point a thread is scheduled.

* Added (configurably) priority ceilings for kernel mutexes

* Support sorted thread queues in kernel, rather than LIFO, controlled by the

  CYGIMP_KERNEL_SCHED_SORTED_QUEUES option.

* The Kernel C API functions cyg_semaphore_wait() and cyg_cond_wait() now

  return booleans to indicate if the wait failed.

* Added enhanced form of kernel message queue which is more flexible at runtime

  than mboxes - available in 

* Add a generic interface in  to allow tables of

  data, particularly initialization data, to be included in an application

  image. This replaces the previous __DEVTAB__ and __NETDEVTAB__ references

  in linker scripts.

* Most standard top-level header files now controlled by the "isoinfra"

  package

* C library package split into separate packages on functional boundaries:

  i18n, setjmp, signals, startup, stdio, stdlib, time

* Most targets now implement a standard form of "virtual vectors" - a

  mechanism to allow enhanced co-operation between ROM monitors and running

  applications. This allows the application to leave to the ROM things that

  the ROM supports rather than duplicating, including debug channels that may

  be via serial or ethernet. To take advantage of this, new GDB stub

  images/CygMon images should be programmed onto boards, although old images

  will continue to work - they will just not be able to use the new facilities.

* DHCP support has been added to the TCP/IP support, in addition to the

  existing BOOTP support

* CDL now supports type bool and booldata for interfaces

* CDL now exports extra macros in header files, to indicate package version

  numbers

* A port of the University of California at Davis (UCD) SNMP stack has been

  added

* Hitachi SH7709A variant support added

* NEC V85x architecture support added

* NEC Cosmo CEB-V850/SA1 evaluation board platform HAL added

* Serial device drivers added for systems based on NEC V850 SA1 (70F3017)

  or SB1 (70F3033) processors

* Hitachi SH3 CqREEK (cq7708) platform HAL support added

  Contributed by Haruki Kashiwaya

* Watchdog reworked much like wallclock.

  Common code and API in io/watchdog, simpler (smaller) low-level drivers in

  devs/watchdog/.

* IO serial driver

  The common serial driver has been extended with a configurable option for

  a non-blocking read/write mode. It has also been given some new callbacks

  which allow low-level drivers to transfer data in blocks instead of as

  single characters.

* SH HAL

  Now provides ROMRAM startup type, copying code and data to RAM before

  executing, improving performance at cost of memory.

* IO serial drivers reworked by separating into distinct platform

  packages, making it simpler to implement new drivers.

* WallClock reworked, making it simpler to implement new drivers.
