eSPI Agent Core, handling of inputs vw_irq0 and vw_irq1?

Hi,

the Intel eSPI Agent Core has two Virtual Wire input groups vw_irq0 and vw_irq1.

If I change the inputs (maybe vw_irq0 from 0x00 to 0x01) the IP core does not signalize this to the host pulling the signal alert# down.

On a GET_VWIRE from the host the eSPI Agent replies with status 0x030F (Virtual Wire TX Queue not available).

If I do the same with the input group ec_to_pch the Agent replies with status 0x34F (

Virtual Wire TX Queue available). Also the signal #alert is pulled down for one cycle by the slave.

So the signals vw_irq0 and vw_irq1 seem not to get handled like other VW signals.

How can I use them?

Regards

Wolfram
