Re: Writing code that takes time to run

Hi, About the code: T_busy(T_get_one_clock_tick_busy() * SOME_CONSTANT); does this support context switch? If task A executing on CPU 1 gets preempted while executing this (by task B) and then comes back on CPU 1 after some time (when task B finishes its execution), would task A finish its exec

[PATCH 3/3] sysinit: Do not open console when just referencing reentrancy structure.

This change eliminates a system initialization dependentcy which resulted in an application without a file system or console referencing errno being forced to include the code to open(/dev/console), close(), atexit(), and the unmount infrastructure. Closes #4439. --- cpukit/include/rtems/confdefs

[PATCH 0/3] minimum.exe Size Reduction Patches

This patch set is the culmination of the recent inquiry into why some BSPs have a minimum.exe around 32K of text and others are twice that. This addresses two unnecessary dependencies that resulted in ~25K reductions in minimum.exe for the jmr3904 and psim BSPs. I plan to make a sweep in the near

As a warning, this and the corresponding libbsd patch are queued behind an RSB patch to get UTIME_NOW and UTIME_OMIT in newlib. That patch was merged into newlib. Then the RTEMS *utime* patch set and these two will go in at the same time. Otherwise, there will be breakage. On Fri, May 21, 2021 at

Building llvm toolchain for RTEMS

Hello, I see some references to llvm toolchains for RTEMS from time to time, but haven't really looked into it. Is it possible to let RSB build a clang C/C++ compiler and kernel for e.g. the Zedboard BSP? If yes, how would I build such a toolchain? I see that there is a llvm buildset in RSB, bu

AW: question about posix timer expiration

Hi Chris, Did you compile ptpd with kqueue only? I’ve tried with posix timer, which are implemented in rtems, but it seems that the handler with siginfo_t is not called correctly. I’ve managed to get it working using a workaround but I’ll continue with kqueue, thx!. Regards, Gabriel Von: Chr
