<div dir="ltr"><font size="2" face="tahoma">====================================</font></div>
<div dir="ltr">This patch contains the next step on the path to SMP support. It adds an<br>
allocated array of the Per_CPU structures to support multiple cpus vs a single<br>
instance of the structure which is still used if SMP support is disabled. <br>
Configuration support was added to explicitly enable or disable SMP. But SMP<br>
can only be enabled for the CPUs which will support it initially -- SPARC and<br>
i386.<br>
<br>
Stub BSP support for SMP was added which lets us treat a single CPU system as a<br>
single core SMP from an RTEMS data structure standpoint. This lets us verify<br>
that we can allocate a array of one per CPU structures, create one IDLE task,<br>
etc.<br>
<br>
The i386 and sparc bsps are modified to be able to run when configured as SMP<br>
using the stub BSP support.<br>
<br>
The NEXT patch adds "real" SMP BSP support for the pc386 and LEON3 BSPs. But<br>
since there is not an SMP aware scheduler yet, it is only exercised by test<br>
programs which verify we can bring cores 2-n out of reset and initialize them.<br>
We have to have an SMP aware scheduler to have tasks scheduled on those cores.</div>
