* bsps: Move interrupt controller support to bspsSebastian Huber2018-04-231-268/+0
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* i386/pc386: Fix interrupt support.Chris Johns2016-05-111-71/+10
| | | | | | | | | | | | 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.

* bsps/i386: SMP and per-CPU thread dispatch disableSebastian Huber2013-08-091-3/+10
| | | | Interrupt support for SMP and the per-CPU thread dispatch disable level.

This adds an allocated array of the Per_CPU structures to support multiple cpus vs a single instance of the structure which is still used if SMP support is disabled. Configuration support is also added to explicitly enable or disable SMP. But SMP can only be enabled for the CPUs which will support it initially -- SPARC and i386. With the stub BSP support, a BSP can be run as a single core SMP system from an RTEMS data structure standpoint. This commit was completely reverted.
