Integrated I/O (IIO) Configuration Registers
14.2.85 MISCCTRLSTS_1
MISC Control and Status Register 1.
4:4 RW 0x0
enable_system_error_only_for_aer:
Applies only to root ports. For Dev#0 in DMI mode, this bit
is to be left at default value always.When this bit is set, the
PCI Express errors do not trigger an MSI or Intx interrupt,
regardless of the whether MSI or INTx is enabled or not.
Whether or not PCI Express errors result in a system event
like NMI/SMI/PMI/CPEI is dependent on whether the
appropriate system error or override system error enable
bits are set or not.
See section titled PCI Express Error Reporting Specifics in
the RAS chapter for details of how this bit interacts with
other control bits in signalling errors to the IIO global error
reporting logic.
When this bit is clear, PCI Express errors are reported via
MSI or INTx and/or NMI/SMI/MCA/CPEI. When this bit is
clear, and ‘System Error on Fatal Error Enable’ bit in
ROOTCON register is set, then NMI/SMI/MCA is (also)
generated for a PCI Express fatal error. Similar behavior for
nonfatal and corrected errors.
