This particular state during a reconsider help request scheduler operation was
only covered by the existing test suites under some timing conditions.
Update #3716.
There were two bugs with MMU page use that were partially hiding each
other. The linker script page table section was 4x the size it needed to
be and the page table allocation routine was allocating pages PTRSIZE
times larger than it needed to. On ILP32, this resulted in incorrect but
functional allocation. On LP64, this resulted in allocation failures
earlier than expected.
At some point during system initialization, the idle threads are created.
Afterwards, the boot processor basically executes within the context of an idle
thread with thread dispatching disabled. On some architectures, the
thread-local storage area of the associated thread must be set in dedicated
processor registers. Add the new CPU port function to do this:
void _CPU_Use_thread_local_storage( const Context_Control *context )
Close#4672.
The compiler wraps fork(), etc. system calls if coverage generation is enabled.
These functions must be provided by the system. For RTEMS, they just return an
error status.
Update #4670.
Allow separate optimization flags for the BSP, cpukit, and tests. For example,
the BSP and cpukit may be built without optimization if coverage
instrumentation is enabled, however, the tests may still use optimization.
Update #4670.
The waf build system uses lists for tool flags. The build items may use
variable substitution. Add the ability to use the variable substitution in
lists. For example:
MORE_FLAGS = ['-more', '-flags']
flags:
- -some-flag
- ${MORE_FLAGS}
Before this change, the ${MORE_FLAGS} was substituted to "-more -flags". This
would be passed by waf as a single command line argument to the tool.
After this change, the ${MORE_FLAGS} list extends the flags list:
flags = ['-some-flag', '-more', '-flags']
This list extension is performed if a list element consists of exactly one
variable.
Update #4670.
Conditional expressions with inline functions are not optimized away if
optimization is disabled. Avoid such expressions to prevent dead
branches. It helps also during code review to immediately see if a loop
is used or not.
Use CLOCK_REALTIME and CLOCK_MONOTONIC for relative thread queue timeouts
instead of CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE. This fixes an
issue with clock_nanosleep() in combination with clock_gettime().
Close#4669.
The original file cpukit/libfs/src/ftpfs/tftpDriver.c
is split into two:
tftpfs.c - This file contains the code from tftpDriver.c
related to file system operations such as mount(),
open(), read(), and so on.
tftpDriver.c - In the original file remains only the code related
to networking. This code implements the Trivial
File Transfer Protocol (TFTP).
Moreover, the code is extended to support
* RFC 2347 TFTP Option Extension
* RFC 2348 TFTP Blocksize Option
* RFC 7440 TFTP Windowsize Option
Update #4666.
