Built-in System Interface<br />
<strong>Intel</strong><br />

Forum<br />
Spring 2001<br />
• For IPMI, three types possible:<br />
– KCS (Keyboard Controller Style) most popular.<br />
– BT (Block Transfer) is fastest.<br />
– SMIC (Server Mgmt. Interface Chip) for<br />
implementation via external ASIC or FPGA.<br />
• Look for “low glue” connection to chip set<br />
– LPC or ISA “X-bus” interfaces commonly used<br />
– IPMI specifications now support memory mapped<br />
implementations as well as original I/O mapped<br />
• Look for System Interface interrupt support<br />

• Multiple Built-in System Interfaces<br />
– KCS interface hardware can be used to<br />
implement an ACPI EC (Embedded Controller)<br />
interface<br />
– Additional interface can support OEM<br />
differentiation access, such as from an SMI<br />
Handler<br />

I 2 C/SMBus Support<br />
<strong>Intel</strong><br />
Developer<br />

Spring 2001<br />
• At least three Master-Slave interfaces recommended:<br />
5V Master-slave capable for IPMB<br />
3.3V Master-slave for PCI Mgmt. Bus<br />
Additional M/S interface for LAN / Future<br />
• Interfaces should support multiple slave addresses<br />
One fixed for I 2 C broadcast (00h)<br />
One programmable for device as IPMI target<br />
Second programmable for snoop/SMBus host target<br />
• SMBus and I 2 C-compatible timing<br />
– Increases implementation options<br />

I 2 C/SMBus Support<br />
<strong>Intel</strong><br />
Developer<br />
Forum<br />
Spring 2001<br />
Support for multiple private management<br />
busses<br />
– Multiple private busses can reduce need for<br />
external I 2 C bus multiplexing<br />
– Hardware-based m/s or slave-only hardwarebased<br />
interfaces are best<br />
– Important for LAN Controller interface performance<br />
– ‘Open drain’ or ‘quasi- bi-directional’ I/O can be<br />
used to create ‘bit banged’ private busses<br />
– Mainly useful for interfacing to sensor devices,<br />
particularly ones that do not require extensive polling<br />

• Option to select open-drain or driven<br />
outputs<br />
– Supports flexible allocation of I/O functions<br />
across products<br />
– Reduces need for external pullups<br />
– Enables software to use I/O as ‘strapping’ inputs<br />
for selecting f/w options<br />
• High-sink outputs (>12mA)<br />

FAN monitoring & control<br />
<strong>Intel</strong><br />
Developer<br />
Forum<br />
Spring 2001<br />
• Timers or Counters for Tach FAN Speed<br />
monitoring<br />
– Tach FAN speed can be accumulated using a<br />
single counter with a digital multiplexer<br />
– FAN speed is calculated by accumulating counts per<br />
unit time, e.g. 1 second.<br />
– Time to accumulate FAN speeds scales with number of<br />
FANs. I.e. monitoring 8 fans takes 8 seconds.<br />
• Pulse-width Modulator (PWM) or D/A<br />
outputs for FAN Speed control<br />

Built-in Analog-to-Digital<br />
<strong>Intel</strong><br />
Developer<br />
Forum<br />
Spring 2001<br />
• Need for at least 7 voltages is common<br />
– E.g. Processor 1 & 2, 3.3V, 3.3Vaux, 5V, 12V, -12V<br />
• Many server systems require more<br />
– >2 processors, SCSI terminations, bus, cache/chipset, etc.<br />
– 19 or more is not uncommon!<br />
• Conversion rate usually not an issue...<br />
– A single converter with analog multiplexing works well<br />
• But accuracy, tolerance, and resolution are<br />
– Recommend at least 8-bit resolution, +/-1 bit tolerance, and<br />
+/-1% accuracy<br />
Low accuracy paid for with system margins<br />

• ROM/RAM upgrade path<br />
– Don’t want to run out of code space for new<br />

• Performance headroom for new functions<br />
such as LAN and Modem access<br />
– Modem interfaces are likely to require protocols<br />
such as PPP<br />
– New LAN and Modem interfaces require<br />
signature algorithms for security<br />

IPMI Firmware / SDK<br />
– Vendors such as Qlogic, Vitesse Semiconductor,<br />
and Winbond offer IPMI firmware for their BMC<br />
and/or Enclosure Controller offerings.<br />
– Typical SDKs support customer-developed<br />
extensions for ‘Value added’ features<br />
– Vendors may also offer customization services<br />
Firmware and SDKs yield faster TTM for<br />
IPMI-based designs<br />

• Server system power increasing -Noise Reduction<br />
becomes more difficult<br />
– Need to meet ISO 7779 and BLUE ANGEL specs<br />
• Desire for more granular speed control<br />
– Audible FAN Speed Cycling can be disconcerting to user<br />
• Need for per-fan or per-zone control<br />
– Driving all fans to same speed usually produces higher<br />
than needed noise level<br />
• Just one tool - not a panacea<br />
– System Engineers still need to design mechanicals and<br />
select low-noise fans<br />

Can often use ‘I 2 C’ devices on PCI<br />
Management bus<br />
… if loading and rise times are compatible<br />
with SMBus and I 2 C specs:<br />
– Bus loading designed to work with I 2 C 3 mA sink<br />
current [or all devices meet 4mA sink capability]<br />
– Bus pullups and capacitance designed to meet<br />
1000 ns Rise Time from 0.65V to 2.54V<br />
I 2 C and SMBus devices can share<br />
same bus. But Master needs to be<br />

Design Recommendations<br />
<strong>Intel</strong><br />
Developer<br />
Forum<br />
Spring 2001<br />
Avoid using slave devices that lack data<br />
integrity checks on the IPMB or PCI<br />
Management Bus<br />
– Many of today’s simple devices don’t have checksums or<br />
error check codes<br />
– Longer bus can have more noise<br />
– A 3rd party firmware error could cause interrupts during<br />
transfers<br />
– ‘Public’ Bus traffic is not deterministic. Poorly behaved<br />
masters could be ‘bus hogs’.<br />
New devices should include SMBus PEC (Packet Error<br />
Check CRC) or use checksums ala IPMI messaging<br />

Put simple, polled slave devices on Private<br />
Management Busses behind ASIC or<br />
Management Controller<br />
– Private management busses have deterministic bandwidth<br />
available for polling and device access<br />
– Private management busses typically have well controlled<br />
noise and loading<br />
– Devices inherit Management Controller data integrity on<br />
IPMB<br />
– Management controllers provide checksummed interface to<br />
private management bus<br />

Page 58
SMBus & I 2 C<br />
Design Recommendations<br />
Management Controller Support for<br />
‘Stuck 0 clear’<br />
– A simple slave that misses a clock on a read transaction<br />
can be left holding the data line low<br />
– Detection requires ability to monitor the bus for a stuck 0<br />
data condition<br />
– Therefore, useful for firmware to be able to directly read state<br />
of bus pins<br />
– Can free bus by clocking it until transfer completes or data<br />
goes to ‘1’<br />
– Requires ability for firmware to clock bus, outputting a ‘1’<br />
until bus clears<br />
– I 2 C/SMBus controller state machine must be able to be<br />
‘overridden’ so that it ignores 0 already on bus.<br />
– One approach: allow firmware to drive bus pins as GPIO<br />

• Check for ‘mid-byte’ START and STOP<br />
Conditions<br />
– Devices should accept START or STOP during<br />

• Check for tolerance to runt pulses<br />
– Most devices behave well under specified<br />

– …but the IPMB may be subject to ‘noise’ or poorcitizen<br />
devices that could ‘glitch’ clock and data lines<br />
