#80 closed enhancement (fixed)

tm27 and nested interrupts (SPARC)

TM27 times interrupts including forcing a nested interrupt.
This test does not run on the SPARC since a patch from
Jiri redoing the handling of the PIL. The SPARC ERC32
and LEON can not properly nest interrupts in HW
as expected by the construction of tm27.

RTEMS-4.5 and Trunk

SPARC but impact is general

Status: assignedclosed

State-Changed-From-To: analyzed->closed
State-Changed-Why: Jiri submitted a patch for the CVS trunk which fixed this

in a way that did not impact any other BSP. I (joel)
modified the patch so that it would apply to 4.5 as well.
The attached tar file includes both patches. They have been
tested on the ERC32 BSP and committed.
