207 Richard Panton of 3G Lab.
208 * Added support for MIPS PMC-Sierra RM7000 variant and Ocelot board, including
209 PCI, ethernet and FLASH support.
210 * Added gzip/zlib decompression support to RedBoot.
211 * Added zlib decompression library.
212 * GDB stubs no longer reboot the board in response to a 'k' packet. Instead
213 from within GDB a "maintenance packet r" must be sent, followed by a
214 "detach". Then you can reconnect to the board.a
215 * Added generic AMD AM29xxxxx flash driver based on MBX driver, and make
217 * Added RedBoot support to PID target.
218 * Added Atmel AT29C040 flash driver.

226 * Added POSIX cancellation points for the sigwait family of functions,
227 pthread_join, pthread_cond_wait, pthread_cond_timedwait, sleep and
229 * Virtual vectors initialization can now be configured with a finer
230 granularity. Diagnostic output should also appear on the same channel
231 (possibly ethernet) as the application was launched from.
232 * Added cyg_pci_find_matching() to PCI library API to allow more generalized
233 matching on device properties.
234 * ARM EBSA285 now configured to use virtual vectors all the time. Users with
235 old GDB stub ROM images should upgrade to newer GDB stub ROM images, or
236 better still to RedBoot.
237 * Stack usage measurement has been added, with the functions
238 pthread_measure_stack_usage() in the POSIX thread API and
239 cyg_thread_measure_stack_usage() in the kernel C API.
240 * Thread stack checking support added. See CYGFUN_KERNEL_THREADS_STACK_CHECKING
241 in the kernel CDL for information.
242 * Add syscall support to RedBoot for compatibility with newlib-based BSPs
243 * Bridge support added to the PCI library. Use cyg_pci_configure_bus() to
244 configure all busses.
245 * Added a port to the Toshiba MIPS TX49 chip, with the REF4955 reference
246 platform. This includes serial device driver and wallclock device driver
248 * PowerPC 40x variant support added.

257 now separate packages. SCIF driver uses full FIFO and can utilize
258 DMA for transmit operations.
259 * Move logical ethernet "driver" into io/eth where the interface can be shared
260 between multiple implementations, e.g. BSD TCP/IP and Red Boot's TCP/IP
262 * RedBoot - the Red Hat Bootstrap ROM monitor has been added, initially
263 supporting ARM-EDB7xxx, ARM-EBSA285, and ARM-Assabet boards. Provides
264 serial and ethernet GDB debugging support, flash image management and flash
265 booting, BOOTP/DHCP and TFTP boot support and a CLI interface.
266 * Added PCMCIA and Compact Flash support, including drivers for the ARM-Assabet
268 * Added generic FLASH memory support
269 * Added flash memory support for ARM-EBSA285 and ARM-EDB7xxx boards
270 * Added Compact Flash Ethernet driver
271 * Hitachi SH7707a variant support added.
272 * Support added for both software and hardware flow control with an initial
273 version of the latter available only for the ARM PID board at present.
274 * Loopback serial device driver added
275 * POSIX termios support added for EL/IX level 1 compatibility
276 * Improved dynamic memory management support in the memory allocator
277 package. Existing dynamic memory support in the kernel (fixed and variable
278 block allocators) and in libc (malloc, etc.) has been moved to this
279 package, located at services/memalloc/common. It is now possible to support
280 memory pools occupying all of remaining memory (as determined by the MLT).
281 New memory allocators can be "plugged in", and an example of Doug Lea's
282 malloc (dlmalloc) has been included.
283 * Plug-in filesystem support added, with a POSIX 1003.1 compatible API, found
284 in the io/fileio package, and integrated with the C library.
285 * An initial example filesystem implementation is provided in fs/ram. This
286 is a RAM filesystem that attempts to both be a useful tool in its own
287 right and an example of how to write a filesystem that plugs into the
288 fileio infrastructure.
289 The source of the filesystem is in fs/ram/VERSION/src/ramfs.c and is
290 intended to be largely self documenting. The General Description at
291 the beginning of the file gives an overview of the structure of the
292 system, and comments within the code explain specific points. This
293 code should be read in conjunction with the description of the fileio
295 * Support added for POSIX 1003.1 threads, mutexes, semaphores, message queues,
296 condition variables, clocks, timers and real-time signals in the POSIX
297 compatibility package (part of the EL/IX compatibility initiative) found at
299 * Kernel enhanced with Asynchronous Service Routines (ASRs) which are routines
300 called back at the point a thread is scheduled.
301 * Added (configurably) priority ceilings for kernel mutexes
302 * Support sorted thread queues in kernel, rather than LIFO, controlled by the
303 CYGIMP_KERNEL_SCHED_SORTED_QUEUES option.
304 * The Kernel C API functions cyg_semaphore_wait() and cyg_cond_wait() now
305 return booleans to indicate if the wait failed.
306 * Added enhanced form of kernel message queue which is more flexible at runtime
307 than mboxes - available in <cyg/kernel/mqueue.hxx>
308 * Add a generic interface in <cyg/hal/hal_tables.h> to allow tables of
309 data, particularly initialization data, to be included in an application
310 image. This replaces the previous __DEVTAB__ and __NETDEVTAB__ references
312 * Most standard top-level header files now controlled by the "isoinfra"
314 * C library package split into separate packages on functional boundaries:
315 i18n, setjmp, signals, startup, stdio, stdlib, time
316 * Most targets now implement a standard form of "virtual vectors" - a
317 mechanism to allow enhanced co-operation between ROM monitors and running
318 applications. This allows the application to leave to the ROM things that
319 the ROM supports rather than duplicating, including debug channels that may
320 be via serial or ethernet. To take advantage of this, new GDB stub
321 images/CygMon images should be programmed onto boards, although old images
322 will continue to work - they will just not be able to use the new facilities.
323 * DHCP support has been added to the TCP/IP support, in addition to the
324 existing BOOTP support
325 * CDL now supports type bool and booldata for interfaces
326 * CDL now exports extra macros in header files, to indicate package version
328 * A port of the University of California at Davis (UCD) SNMP stack has been
330 * Hitachi SH7709A variant support added
331 * NEC V85x architecture support added
332 * NEC Cosmo CEB-V850/SA1 evaluation board platform HAL added
333 * Serial device drivers added for systems based on NEC V850 SA1 (70F3017)
334 or SB1 (70F3033) processors
335 * Hitachi SH3 CqREEK (cq7708) platform HAL support added
336 Contributed by Haruki Kashiwaya
337 * Watchdog reworked much like wallclock.
338 Common code and API in io/watchdog, simpler (smaller) low-level drivers in
339 devs/watchdog/<arch>.
341 The common serial driver has been extended with a configurable option for
342 a non-blocking read/write mode. It has also been given some new callbacks
343 which allow low-level drivers to transfer data in blocks instead of as
346 Now provides ROMRAM startup type, copying code and data to RAM before
347 executing, improving performance at cost of memory.
348 * IO serial drivers reworked by separating into distinct platform
349 packages, making it simpler to implement new drivers.
350 * WallClock reworked, making it simpler to implement new drivers.
