Register Description
Intel® 5000P/5000V/5000Z Chipset Memory Controller Hub (MCH) Datasheet
Note that the Assert_intx/Assert_HPGPE message is sent to ESI port when any of the
events defined in bits[4:0] (CMDCOMP,PRSINT, MRLSC, PWRINT, ABP) of the
PEXSLOTSTS register are set provided the corresponding events in bits [4:0] of the
Section 3.8.11.10
MCH will send a Deassert_HPGPE message to ESI port (wired-OR).
For the case when MSI is enabled, any new event that sets these bits (e.g ABP, PRSINT
and so forth) will cause an MSI message to be sent to the FSB for each occurrence.
That is, each bit is considered unique.
Whereas in the case of Legacy interrupts, a wired-OR approach is used to mimic the
level sensitive behavior and only one assert_intx/assert_GPE (deassert_intx/
deassert_GPE) is sent even when multiple interrupt generating bits of the register get
set. Refer to
