Do not use the interface mutex in the receive loop. Avoid multiple
reads of DMA descriptor words. Use a compile-time constant for the
receive DMA descriptor count to simplify calculations.
Update #4652.
Use the transmit interface handler to avoid a transmit task/interrupt.
Use a compile-time constant for the transmit DMA descriptor count to
simplify calculations.
Update #4652.
The pppstart expected that a driver write would somehow magically
process all data passed to the write function. Because ppp disables all
buffering that originally has been in termios, that assumption is not
true for all but polled drivers.
With this patch, the pppstart now gets and processes the feedback that
is returned from the driver via rtems_termios_dequeue_characters.
Fixes#4493
When the cmpset and fcmpset functions were refactored, the return value
of the operation was discarded instead of being returned for SMP builds
outside of gcc 4.x. This had the effect of turning these functions into
a long busywait loop that eventually failed due to integer overflow.
This patch restores the use of the return value of the atomic
operations.
- The script's use of sort proved to not be portable
- No need to check the commits as symbols are only added
- Regenerated kernel header to reset the sort order
Update #4475
- Add PCI IO region support
- Add support map buffers to PCI address space
- Add BSP conditional IO space support. Some PC implementations
have PCI IO space mapped differently to memory space and this needs
to be reflected in the busspace.
- Include bsp.h to pick per BSP configuration.
Closes#4245
This alters the selection of the 4 Cadence GEM interfaces on the Zynq
Ultrascale+ MPSoC BSP to be provided by config.inc instead of being
provided by options in the RTEMS BSP itself since those options appear
to be dead code when not used in conjunction with LibBSD.
Updated ttcp.c to build clean for RTEMS 6 and the machines it
originally built for. Also fixed ttcp.c to close network
sockets after completion. Defined a shell command for TTCP in
rtems-bsd-shell-ttcp.c. Added TTCP to the list of RTEMS network
commands in netcmds-config.h. Added declaration of the TTCP shell
command to rtems-bsd-commands.h. Modified libbsd.py to make waf
build TTCP and its shell command.
Added the original Test TCP (TTCP) program in unmodified form.
Also added the original README for TTCP. Both the README and the
TTCP program were sourced from the first commit in the RTEMS
network demos repository.
Since the epoch call callbacks may lock/unlock a mutex the callbacks must be
called from within thread context with thread dispatching enabled. Use thread
pinning to ensure that the calling thread stays on the right processor. Use
the interrupt server to ensure the thread context for the epoch drain.
Changed nfs_utime() to nfs_utimens(), changed the arguments to use
a timespec array instead of individual variables for access and
modified time.
Updates #4400
Possible data sources for SD driver:
- mmc_sd_switch():
- length: 64 byte;
- buffer on stack
- mmc_test_bus_width():
- length: 4 or 8 byte
- buffer in program memory or on stack
- mmc_app_send_scr():
- length: 8 byte
- buffer from device ivar structure
- mmc_app_sd_status():
- length: 64 byte
- buffer from device ivar structure
- mmc_send_ext_csd():
- length: MMC_EXTCSD_SIZE = 512
- buffer from device ivar structure
- rtems_bsd_mmcsd_disk_read_write():
- length: depends on read
- buffer from rtems_blkdev buffer -> already aligned
- mmcsd_ioctl_cmd():
- length: depends on call
- buffer malloced, not aligned -> patched in RTEMS
So the problematic buffers are only the ones up to 512 bytes. Copy these data
into a buffer to avoid that problem.
