Hi guys.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
I faced a problem with intrusion sensor on a Lewisburg C621 PCH.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
In dbus-sensors there is intrusion sensor daemon which intended to work</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
with Lewisburg PCH, but there is only code to read intruder state (INTRD_DET) and</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
no any mention about intrusion sensor reset (ChassisIntrusionSensor.cpp). </div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
We are looking for a way <font size="3"><span style="font-size: 12pt;">to reset </span></font><font size="3"><span style="font-size: 12pt;">INTRD_DET</span></font><font size="3"><span style="font-size: 12pt;"> from BMC.</span></font></div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">

</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
According to the C621 datasheet, this bit must be cleared by writing 1 to it. </div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
But reading the documentation led to the conclusion that one set of registers is </div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
available for reading via SMBUS (table 26-8 of the C621 datasheet), </div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
and for writing - another (table 26-5). Probably the idea of the C621 developers </div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
is that the INTRD_DET bit can both be read and cleared via PCIe, but only read via SMBUS?</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
If it isn't possibly to <font size="3"><span style="font-size: 12pt;">reset intruder from intrusion sensor, how it supposed to work in Intel </span></font><font size="3"><span style="font-size: 12pt;">BMC?</span></font></div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
Or is there some way to clear this bit over SMBUS?</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
