* 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.

| | | | | | | This avoids potential dead code in _Thread_Handler(). It gets rid of the dangerous function pointer casts. Update #2514.
* 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
| | | | | | Use the bsp_predriver_hook() instead. Update #2408.
* 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.
