FRU(s) Component(s) Failure Description
Local non-device interrupt test
x = 1 for CE interrupt testing, 2 for UCE interrupt testing, 3 for SE interrupt testing
001x QBBx.CPUy
QBBx QSDz (z=0 - 3)
NO IRQ interrupt posted to CPU
002x Incorrect IRQ int posted to CPU
010x Invalid CPU ID in error summary CSR
020x No QBB_NUM bits set in error summary CSR
040x Incorrect QBB_NUM set in error summary CSR
080x More than one QBB bit set in error summary
CSR
011x No IRQ int to CPU. Invalid CPU id in error CSR
021x No IRQ int to CPU. No QBB_NUM in error CSR
041x No IRQ int to CPU. Incorrect QBB_NUM set in
error CSR.
081x No IRQ int to CPU. More than one QBB bit set in
error CSR
012x Incorrect IRQ int to CPU. Invalid CPU id in error
CSR.
022x Incorrect IRQ int to CPU. No QBB_NUM in error
CSR.
042x Incorrect IRQ int to CPU. Incorrect QBB_NUM
set in error CSR
082x Incorrect IRQ int to CPU. More than one QBB bit
set in error CSR.
101x No IRQ int to CPU but QSDs error summary
CSR is correct. FRU is likely QSDx->CPUx path
102x Incorrect IRQ int to CPU but QSD’s error
summary CSR is correct. FRU is likely QSDx-
