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
