* termios: Synchronize with latest FreeBSD headersKevin Kirspel2017-03-221-1/+1
| | | | | | | | | | | Adding modified FreeBSD headers to synchronize RTEMS termios with FreeBSD. Modify termios to support dedicated input and output baud for termios structure. Updated BSPs to use dedicated input and output baud in termios structure. Updated tools to use dedicated input and output baud in termios structure. Updated termios testsuites to use dedicated input and output baud in termios structure. Close #2897.
* bsps/i386: use Pentimum instructions for pc586 and pc686 builds.Pavel Pisa2016-10-172-2/+2
| | | | | | | | | | | | | | | | | | When GCC option -march is not specifies i386-rtems toolchain defaults to i386 architecture instruction set. It does not provide atomic instructions which results in really inefficient atomic_fetch_or even on UP build. SMP build is broken with i386 set because libatomic and GCC generate infinite loop for __atomic_fetch_add_4 used in rtems_interrupt_lock_acquire __atomic_fetch_add_4: push %ebp mov %esp,%ebp movl $0x5,0x10(%ebp) pop %ebp jmp __atomic_fetch_add_4

* bsps/i386: Separate variable for i8259 IRQs disable due to in progress state.Pavel Pisa2016-10-111-19/+36
| | | | | | | | The global state of enabled and disabled interrupts has to hold interrupts really disabled by drivers and system. If the state is combined with interrupts temporarily disabled because they are processed at given time then it is impossible to maintain state by interrupt handlers in drivers.

* i386/pc386: Fix interrupt support.Chris Johns2016-05-119-172/+471
| | | | | | | | | | | | Fix the interrupt and stop the spurious interrupt from happening. The fix moves the EOI to C code and cleans that functionality out of the asm part of the ISR handler. The code checks the ISR and IRR registers on the enable. Only ack the master for a slave IRQ if the slave has no other pending requests.

* i386/pc386: Add support for the gdb stub to use available console drivers.Chris Johns2016-05-1115-424/+701
| | | | | | | | | | | Move the gdb stub from the i386 UART code to use the libchip drivers. Use any ports discovered during the probes. Add gdb control to the boot command line. Change the device naming to the full device path, not a partial path. For example /dev/com1.

* pc386: Improve boot command arguments for console/printk device selectionJoel Sherrill2016-03-103-39/+156
| | | | | | | | This patch adds the "--printk=" boot command line argument to specify the printk() device. It also enhances the "--console=" boot command line argument to match any device configured in the console device table. The arguments are parsed as early as possible so they take effect early. Currently, this is immediately after PCI initialization.
* Add shared PCI support and enhance pc386 to support non-legacy PCI ↵Joel Sherrill2016-03-106-135/+252
| | | | | | | | | | | | | | | configuration space This patch fundamentally results from enhancements to the pc386 BSP to support systems which do **NOT** have the legacy PCI BIOS. The patch adds support for detecting when legacy PCI BIOS is not present and then using IO space to access to PCI Configuration Space. This resulted in dynamically selected between two implementations of PCI and refactoring out the shared methods. This patch adds shared implementations of pci_bus_count() and pci_find_device(). Subsequent patches will remove implementations of these methods in other BSPs where possible.

* pc386: Eliminate pcibios.h and begin removal obsolete PCI BIOS API usesJoel Sherrill2016-03-105-87/+25
| | | | | | | | | | | | | | | | | | | | This first step eliminates the following as public APIs for the pc386 BSP: + pcib_conf_read8 + pcib_conf_read16 + pcib_conf_read32 + pcib_conf_write8 + pcib_conf_write16 + pcib_conf_write32 The if_fxp.c driver uses these enough where I provided local macros to allow the code to be mostly unmodified. On other architectures these names have been used privately. It will take multiple patches to completely eliminate these symbols from the RTEMS source tree. The focus of the first effort is just to eliminate these as a public pc386 API so support can be added for systems without legacy PCI BIOS.

* api: Remove deprecated NotepadsAun-Ali Zaidi2015-12-242-4/+0
| | | | | | | | | | | | | | | | | | | | | | | Notepads where a feature of RTEMS' tasks that simply functioned in the same way as POSIX keys or threaded local storage (TLS). They were introduced well before per task variables, which are also deprecated, and were barely used in favor of their POSIX alternatives. In addition to their scarce usage, Notepads took up unnecessary memory. For each task: - 16 32-bit integers were allocated. - A total of 64 bytes per task per thread. This is especially critical in low memory and safety-critical applications. They are also defined as uint32_t, and therefore are not guaranteed to hold a pointer. Lastly, they are not portable solutions for SMP and uniprocessor systems, like POSIX keys and TLS. updates #2493.
* bsps: Delete superfluous bsp_pretasking_hook()Sebastian Huber2015-12-101-1/+0

* bsps: Call bsp_work_area_initialize() earlySebastian Huber2015-12-103-10/+10
| | | | | | | | Call bsp_work_area_initialize() before bsp_start(). This allows bsp_start() to use malloc() etc. which is beneficial for systems with a plug-and-play hardware enumeration. Update #2408.
