The previous timeout handling was flawed. In case a waiting thread
helped out the owner could use the scheduler node indefinitely long.
Update the resource tree in _MRSP_Timeout() to avoid this issue.
Bug reported by Luca Bonato.
Some file systems do not support sync() at all and return an
error indicating this on any sync() call. In particular, the
IMFS is one of these and thus this assertion is tripped in
normal testing.
Since sync() is void per POSIX, the error just must be ignored.
The dummy.c was a de-facto default configuration. Rename it to
default-configuration.c. Use unlimited objects and the stack checker.
This makes it easier for new RTEMS users which will likely use this file
if they just work with the usual main() function as the application
entry point. Provide proper arguments for main() using the BSP command
line. Add spare user extensions and drivers.
Do not initialize the network by default. Delete bspinit.c.
On recent u-boots, the watchdog is turned on / left enabled. The
Beaglebone Black rev. C ships with such a u-boot internally so any
application booting from it must disable the watchdog.
Therefore this change is needed to boot an RTEMS app out-of-the-box
on a BBB Rev C - otherwise the user button must be held during boot
(to bypass the stock uboot) or the internal uboot must be updated. To
allow for a better out-of-the-box experience, we just turn off the
watchdog.
fb_vesa_rm.c: removed inline from functions declared in fb_vesa.h
removed unnecessary printks in the end of patch
edid.h, vbe3.h: switched from custom *PACKED_ATTRIBUTE at the structs to the
RTEMS_COMPILER_PACKED_ATTRIBUTE for easier maintainability
of doxygen
* Coding style cleanups.
* Use OS reserved trap 0x89 for IRQ Disable
* Use OS reserved trap 0x8A for IRQ Enable
* Add to SPARC CPU supplement documentation
This will result in faster Disable/Enable code since the
system trap handler does not need to decode which function
the user wants. Besides the IRQ disable/enabled can now
be inline which avoids the caller to take into account that
o0-o7+g1-g4 registers are destroyed by trap handler.
It was also possible to reduce the interrupt trap handler by
five instructions due to this.
Previously, bankValidate() could be called (e.g., BSP_flashWrite() -> regionCheckAndErase() -> argcheck() -> bankValidate()) without the probe having happened. When it then invoked BSP_flashCheckId(), unmapped memory could be read, possibly causing a fatal exception.
Save five instructions on underflow handling.
By using an optimized trap entry we can move instructions from
the window underflow function into the trap entry vector. By
setting WIM=0 and using RESTORE it is possible to move the
new WIM register content from the trapped window into the
to-be-restored register window. It is then possible to avoid
the WIM write delay.
By using a optimized trap entry we can move instructions from
the window overflow function into the trap entry vector. By
using the saved locals instead of g1 we don't need to save
that register temporarily. Also spead out non store instructions
inbetween stores to use the write buffer better.
The LEON3 BSP have support for up to 8 termios consoles, the
LEON3-FT GR712RC uses 6 UARTs.
This does not take into account the BSP maximum devices instead
it is hardcoded to 6. This patch increases it the maximum
devices of DEVFS04 from 6 to 10.
