* score: Avoid cyclic header file dependenciesSebastian Huber2023-04-253-60/+115
| | | | | | | | | | | | | There was a cyclic dependency: For RTEMS_STATIC_ANALYSIS we needed basedefs.h in assert.h. For RTEMS_UNREACHABLE() we needed _Assert() from assert.h in basedefs.h. Fix this by introducing _Debug_Unreachable() in basedefs.h. Add RTEMS_FUNCTION_NAME to basedefs.h and use it in basedefs.h and assert.h. Close #4900.

* cpukit/jffs2: Add support for NAND under JFFS2Kinsey Moore2023-03-1518-40/+581
| | | | | | | | | This adds write buffer and bad block support required for JFFS2 operation on NAND devices. This also adds the minor modifications necessary for RTEMS support in the Linux header stubs and in wbuf.c. Memory and NOR backed applications should experience no difference in operation since they do not expose the callbacks required for write buffer support.

| | | | | This pulls in wbuf.c from the upstream Linux repository at the state specified in VERSION.
* cpukit/jffs2: Initialize and lock mutexesKinsey Moore2023-03-152-0/+4
| | | | | Mutexes must be locked before they can be unlocked. JFFS2 doesn't currently see this as an issue because all mutex operations are no-ops.

* Provide kernel space items only if neededSebastian Huber2023-03-146-18/+30
| | | | | | | The kernel space parts of standard system header files were protected against misuse by a preprocessor error directive. This approach does not work well with tools such as Doxygen. Provide the kernel space items only if the required defines are present.
* pps: Round to closest integer in pps_event()Sebastian Huber2023-03-071-1/+3
| | | | | | | | | | | | | | The comment above bintime2timespec() says: When converting between timestamps on parallel timescales of differing resolutions it is historical and scientific practice to round down. However, the delta_nsec value is a time difference and not a timestamp. Also the rounding errors accumulate in the frequency accumulator, see hardpps(). So, rounding to the closest integer is probably slightly better. Reviewed by: imp Pull Request: https://github.com/freebsd/freebsd-src/pull/604
* pps: Simplify the nsec calculation in pps_event()Sebastian Huber2023-03-072-19/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let A be the current calculation of the frequency accumulator (pps_fcount) update in pps_event() scale = (uint64_t)1 << 63; scale /= captc->tc_frequency; scale *= 2; bt.sec = 0; bt.frac = 0; bintime_addx(&bt, scale * tcount); bintime2timespec(&bt, &ts); hardpps(tsp, ts.tv_nsec + 1000000000 * ts.tv_sec); and hardpps(..., delta_nsec): u_nsec = delta_nsec; if (u_nsec > (NANOSECOND >> 1)) u_nsec -= NANOSECOND; else if (u_nsec < -(NANOSECOND >> 1)) u_nsec += NANOSECOND; pps_fcount += u_nsec; This change introduces a new calculation which is slightly simpler and more straight forward. Name it B. Consider the following sample values with a tcount of 2000000100 and a tc_frequency of 2000000000 (2GHz). For A, the scale is 9223372036. Then scale * tcount is 18446744994337203600 which is larger than UINT64_MAX (= 18446744073709551615). The result is 920627651984 == 18446744994337203600 % UINT64_MAX. Since all operands are unsigned the result is well defined through modulo arithmetic. The result of bintime2timespec(&bt, &ts) is 49. This is equal to the correct result 1000000049 % NANOSECOND. In hardpps(), both conditional statements are not executed and pps_fcount is incremented by 49. For the new calculation B, we have 1000000000 * tcount is 2000000100000000000 which is less than UINT64_MAX. This yields after the division with tc_frequency the correct result of 1000000050 for delta_nsec. In hardpps(), the first conditional statement is executed and pps_fcount is incremented by 50. This shows that both methods yield roughly the same results. However, method B is easier to understand and requires fewer conditional statements.

* pps: Simplify capture and event processingSebastian Huber2023-03-071-21/+21
| | | | | | | | | | | | | | Use local variables for the captured timehand and timecounter in pps_event(). This fixes a potential issue in the nsec preparation for hardpps(). Here the timecounter was accessed through the captured timehand after the generation was checked. Make a snapshot of the relevent timehand values early in pps_event(). Check the timehand generation only once during the capture and event processing. Use atomic_thread_fence_acq() similar to the other readers.

| | | | | | | | | | | | Since 32c203577a5e by phk in 1999 (Make even more of the PPSAPI implementations generic), the "nsec" parameter of hardpps() is a time difference and no longer a time point. Change the name to "delta_nsec" and adjust the comment. Remove comment about a clock tick adjustment which is no longer in the code.

* kern_tc.c/cputick2usec()firk2023-03-071-9/+3
| | | | | | | | | | | | | | | | | | (which is used to calculate cputime from cpu ticks) has some imprecision and, worse, huge timestep (about 20 minutes on 4GHz CPU) near 53.4 days of elapsed time. kern_time.c/cputick2timespec() (it is used for clock_gettime() for querying process or thread consumed cpu time) Uses cputick2usec() and then needlessly converting usec to nsec, obviously losing precision even with fixed cputick2usec(). kern_time.c/kern_clock_getres() uses some weird (anyway wrong) formula for getting cputick resolution.
