* arm: Fix ARMv7-M interrupt processing4.11.2Sebastian Huber2017-07-072-30/+48
| | | | | | | | | | | | Right after a "msr basepri_max, %[basepri]" instruction an interrupt service may still take place (observed at least on Cortex-M7). However, pendable service calls that are activated during this interrupt service may be delayed until interrupts are enable again. The _ARMV7M_Pendable_service_call() did not check that a thread dispatch is allowed. Move this test from _ARMV7M_Interrupt_service_leave() to _ARMV7M_Pendable_service_call(). Close #3060.
* bsps/arm: Fix bit field offset in GIC supportSebastian Huber2017-05-111-1/+1

* libdl: Back port C++ exception throw and catch from 4.12.Chris Johns2017-04-0462-275/+4754
| | | | Closes #2956.
* dosfs: Fix file name searchSebastian Huber2017-03-212-18/+17
| | | | | | | Do not use our long file name entry count to optimize the file name search. The Unicode comparison must be taken into account. Close #2939.
* dosfs: Fix race condition msdos_dir_read()Sebastian Huber2017-03-211-5/+5
| | | | | | Obtain file system instance lock before member access. Close #2937.
* dosfs: Rename fat_entries to lfn_entriesSebastian Huber2017-03-211-20/+20
| | | | | The name "fat_entries" for long file name directory entries is quite misleading.

| | | | Close #2934.

| | | | | | Make sure that long file names work accross cluster boundaries. Close #2929.

* dosfs: Fix fat_file_write()Sebastian Huber2017-03-2110-36/+183
| | | | | | | | Remove forced overwrite which leads to file data corruption. The logic to determine a forced overwrite was fundamentally broken. For simplity, disable this feature. Close #2622.
* dosfs: Fix msdos_utf8_normalize_and_fold()Sebastian Huber2017-03-212-5/+22
| | | | | | | | It is all right in case the result uses the full destination buffer. Without this fix the handling of a maximum 8.3 short file name is broken. Close #2928.
* libio: Fix deadlock in location managementSebastian Huber2017-03-218-15/+19
| | | | | | | | Perform a context-dependent deferred location release to avoid a deadlock on the file system instance locks, for example during a chdir(). Close #2936.

| | | | Closes #2827.
* termios: Fix infinite loop in receive pathSebastian Huber2017-02-281-5/+9
| | | | | | | In canonical mode, the raw input buffer or the canonical buffer may overflow without an end of line. Avoid an infinite loop in this case. Update #2915.
* termios: Protect raw input buffer with device lockSebastian Huber2017-02-281-16/+36
| | | | | | | Use the device lock to protect the raw input buffer management, e.g. tail, head and buffer content updates. Update #2914.
* termios: Simplify rtems_termios_read_tty()Sebastian Huber2017-02-281-9/+4
| | | | | | Remove dead code. Update #2914.
* dosfs: Fix FAT32 formatterSebastian Huber2017-02-281-2/+2
| | | | | | | | | The second FAT entry contains a bit to indicate if the FAT32 filesystem is not dirty and a bit to indicate if there was no IO error. Set both bits for a fresh filesystem. This prevents a warning if mounted on Windows. Update #2913.

* libdl/rtl-obj.c: synchronize cache should not depend on CPU_CACHE_LINE_BYTES.Pavel Pisa2016-10-031-3/+6
| | | | | | | | | | The CPU_CACHE_LINE_BYTES has been introduced after 4.11 branch fork and is not available for all architectures on RTEMS 4.11. Use of rtems_cache_get_maximal_line_size() is more descriptive choice. The min/max data/instruction cache line size is not critical there, value is used for optimization only to use single operation for decently following sections.

* arm/tms570: include hardware initialization and selftest based on Ti ↵Pavel Pisa2016-10-0216-0/+3519
| | | | | | | | | | | | | | | | | | | | HalCoGen generated files. The configuration is specific for TMS570LS3137 based HDK. Pins configuration can be easily changed in rtems/c/src/lib/libbsp/arm/tms570/hwinit/init_pinmux.c file. The list tms570_selftest_par_list in the file rtems/c/src/lib/libbsp/arm/tms570/hwinit/bspstarthooks-hwinit.c specifies peripherals which health status is examined by parity self-test at BSP start-up. It can be easily modified for other TMS570 family members variants same as the selection of other tests in bspstarthooks-hwinit.c.
* arm/tms570: define base addresses of all TMS570LS3137 SPI interfaces.Pavel Pisa2016-10-021-1/+5
| | | | | | | | Generated header file ti_herc/reg_spi.h contains complete registers and fields set for Ti MibSPI peripheral. Care has to be taken that only TMS570_SPI1, TMS570_SPI3 and TMS570_SPI5 are of this complete multibuffer type. TMS570_SPI2 and TMS570_SPI4 have substantial part of registers removed but else they are compatible.
* bsp/tms570: ensure that change of SCI baudrate is not applied in the middle ↵Pavel Pisa2016-10-021-2/+23
| | | | | | | | | | | | | | | | | | | of character Tx. The rtems_monitor_task() setups/updates termios attributes of the opened TTY and if there is ongoing some other output it leads to the stuck. It would be better to use some termios API function which would call drainOutput() in rtems/cpukit/libcsupport/src/termios.c. But functionality is not accessible outside of core termios implementation. The loop waiting for last character to be sent has to be there anyway because hardware does not provide Tx machine/shift register empty interrupt. Closes #2794

| | | | | | | | The symbol can be used by bsp_start_hook_0 when complete RAM memory is initialization and overwritten during BSP self-test. The test overwrites even memory used to store return address / link register and regular resturn from bsp_start_hook_0 is not possible then.

This is minimized version of mainline patch arm/raspberrypi: move MMU in front of application image to respect variable memory size. plus correction which has been part of other mainline patches.

* arm/raspberrypi: remove duplicate setup of IRQ handler in the main ARM ↵Pavel Pisa2016-10-022-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | exception table. Exception table setup is processed by common CPU architecture support. For ARM architecture, it can be found in the file rtems/c/src/lib/libbsp/arm/shared/start/start.S and ends by bsp_vector_table_copy_done label. The actual tabel content can be found at bsp_start_vector_table_begin For ARMv7-A and even other variant with hypervisor mode support, it is even not necessary to copy table to address 0 at all because CP15 register can be used to specify alternative table start address arm_cp15_set_vector_base_address(&)bsp_start_vector_table_begin; ARMv7-M have register to set exception table base as well.

Because major part of application usually fits to the first megabyte this speedups test dhrystone application by factor 40. Updates #2783
* arm/raspberrypi: Enable HYP to SVC switch for this BSP.Pavel Pisa2016-10-022-0/+7
