| * libblock: Add rtems_bdbuf_set_block_size()Sebastian Huber2012-04-126-85/+165
| | | | | | | | | | | | | | | | The new function rtems_bdbuf_set_block_size() must be used to set the block size of a disk device. It will check if the block size is valid and set the new fields block_to_media_block_shift and bds_per_group of the rtems_disk_device structure. This helps to avoid complex arithmetic operations in the block device buffer get and read path.

| | | | | | | | | | Calling the bdbuf API functions in the not configured state is now a fatal error.

* | Filesystem: IO control based select() supportSebastian Huber2012-04-033-4/+124
| | | | | | | | | | This is a hack. The Termios write facility has a severe issue with the lacking support of non-blocking writes.

| | | | | | | | | | | | | | | | | | | | o Move rtems_bsdnet_fdToSocket() and rtems_bsdnet_makeFdForSocket() to "cpukit/libnetworking/rtems/rtems_syscall.c". o The rtems_bsdnet_makeFdForSocket() function is now static. o Check in rtems_bsdnet_fdToSocket() function that the file descriptor uses the socket handlers, otherwise an error status will be returned and errno set to ENOTSOCK. o New test libtests/syscall01.

* | PR2040: libblock: Add starvation thresholdSebastian Huber2012-04-021-1/+15
| | | | | | | | | | | | Do not use the unavailable block count as the erased blocks starvation threshold. Use instead the block count of the largest segment. This improves the starvation resolution gain of available blocks.

* Add Virtex4 and Virtex5 BSPsRic Claus2012-03-301-1/+78
| | | | | | | | | | | | | | | | | This commit covers at least PR2020, 2022, and 2023. This patch adds all of the code for both BSPs, modifications to libcpu/powerpc for the ppc440, and some updates to the BSPs from follow up review and testing. These BSPs should be good baselines for future development. The configurations used by Ric are custom and have a non-standard NIC. They also do not have a UART. Thus the current console driver just prints to a RAM buffer. The NIC and UART support are left for future work. When the UART support is added, moving the existing "to RAM" console driver to a shared location is likely desirable because boards with no debug UART port are commonly deployed. This would let printk() go to RAM.

* confdefs: Add declaration for unlimited objects.Gedare Bloom2012-03-271-1/+107
| | | | | | | | | Adds to confdefs a way to specify rtems_resource_unlimited for classic and posix objects using a new macro CONFIGURE_OBJECTS_UNLIMITED. Use CONFIGURE_OBJECTS_ALLOCATION_SIZE to declare the allocation size for extending the set of objects at runtime. Updates the unlimited sample to demonstrate how to use the new macros. Also adds new documentation in the C User's Manual regarding configuring with unlimited objects.
