Abstract

A remote monitor module is provided to monitor initialization events of a computer host domain on a local mainboard. The remote module includes an event monitor to detect certain initialization events during system initialization process, and then generates and transmits event signals to a BMC (Baseboard Management Controller). A decoder may be used to decode BIOS check data at a specific I/O address and provides check data signals to the BMC. The BMC receives the event signals and/or the check data signals and transmits to a remote management host through remote management link(s).

Description

Remote monitor module for computer initialization
Technical field
The invention relates to computer initialization, particularly a kind of remote monitor module of computer initialization.
Background technology
Most at present regional mainboards have the feature that specific debug, test and problem are repaired in the process of system initialization.Yet those features are not easy to be used with external device (ED) or telemonitoring main frame usually.The most just features of substrate level of these features.In addition, the carrying out of test assignment (for example: 7 sections LED lamps), unless pilot lamp is arranged at the casing outside, otherwise monitor that these tasks need external test facility only is shown on the pilot lamp that is positioned at substrate.For the knife edge or cluster system, these pilot lamp only can provide not enough systemic hierarchial management in the stage of system initialization.
Be illustrated in figure 1 as a typical old-fashioned embodiment of the regional mainboard of computer system in the routine techniques, zone mainboard 01 (Local mainboard) comprises the main frame field 10 (computer host domain) of running as same computing machine, and main frame field 10 mainly comprises one or more processor 11, the Installed System Memory (not shown), in be built in BIOS (basic input/output system basicinput/output system or initial code initialization codes) 13 on the internal memory, system chipset 12 is connected between processor 11 and the BIOS13, power supply unit and other system element (all not showing among the figure).System's input/output bus 40 (system I/O bus), for example: the bus of lpc bus or PCI basis (PCI-based) connects main frame field 10 with code translator 30 and other input/output device (not shown).Baseboard management controller 20 (BMC, Baseboard Management Controller) connects main frame field 10 and sees through the telemanagement link with circuit provides telemanagement main frame remote inspection/control ability.
The process of system initialization has two main portions, and the one, at first acquisition initial code (BIOS) before, another is after beginning to capture BIOS13.In case the BIOS13 initialization output unit, for example: video display (video display) or serial port (serial ports) have in routine techniques that particular software application can be pointed out in order to disposal system, test and a problem reparation.Yet some information such as: BIOS checks that data (check data) (comprising the checkpoint information (check point information) in order to point out the BIOS initial phase immediately) are not can see through these software programs obtain.Extensively provide the inspection data in the duration that first acquisition BIOS is initialized to output unit.
A kind of function for monitoring feature that is generally used for monitoring x86 base computer systems BIOS13 debug process and is called as " Port80 " is that the code translator 30 by I/O address 0x0080 (or Port80) response on system's input/output bus 40 is provided.During the BIOS13 initialization procedure, BIOS13 sees through system's input/output bus 40 and writes aforementioned inspection data to code translator 30.Code translator 30 deciphers are checked data and are shown in indicator 31 then.When the system initialization process was stagnated in the somewhere, visible inspection data made the user be found and confirm the problem of system hardware on the indicator 31.Yet the baseboard management controller 20 of the common ability of tool also can't be supported this function.Because old-fashioned baseboard management controller 20 and code translator 30 are independent mutually between the two, so the telemanagement main frame of routine techniques can't be checked data through baseboard management controller 20 supervision.
Except that checking data, initialization event in the system initialization process, for example: " electric power kilter (power good status) ", " discharge reset (releasing reset) ", " first BIOS acquisition (first BIOS fetch) " or the like, by bus protocol (indicate acquisition for the first time, discharge and reset), some other particular monitored circuit (as temperature, fan speed, electric power abundance state) of system's input/output bus 40 or directly provided by hardware element (as power supply unit) as BIOS.Yet common baseboard management controller 20 there is no design in order to take the customized function of (access) these initialization events.Also there is no other surveillance equipment in routine techniques handles these customized monitor tasks and is sent to display.Therefore, these initialization events do not send or are shown in indicator 30, also can't provide to the telemanagement main frame.Want the observing system initialization event, the user must use an oscillograph or logic analyser usually.
Summary of the invention
Therefore, the present invention sees through a remote monitor module provides system initialization information to give the telemanagement main frame.Basically, the additional circuit on regional mainboard will be in order to obtain system status information and to be sent to the district management circuit, for example: baseboard management controller.The telemanagement main frame is just seen through the telemanagement link and is taken this information then.

Embodiment
See also Fig. 2, some regional mainboards 01 are integrated as a computing system.Each regional mainboard 01 sees through the telemanagement link and is connected in telemanagement main frame (not shown).The telemanagement link is compatible with IPMI (IPMI, Intelligent Platform Management Interface) specification definition communication link (communication links) down, for example: between regional mainboard, see through system's input/output bus, network interface (NIC controller and connector), serial port, even the communication link of System Management Bus.
Zone mainboard 01 mainly comprises main frame field 10, system's input/output bus 40 and remote monitor module 50.
Main frame field 10 running as same computing machines comprise one or multiprocessor 11, Installed System Memory (not shown), BIOS (basic input/output system Basic Input/Output System or initial code initialization codes) 13, system chipset (system chipset) 12, power supply unit (not shown) and other system element (not shown) of running as same bridge interface (bridge interface) between processor 11 and BIOS13 usually.In certain embodiments, processor 11 has Memory Controller Hub therein, for example: the x86 processor on AMD framework basis, with the direct access Installed System Memory.Desire the access system internal memory for being unkitted the processor of being furnished with Memory Controller Hub, internal memory center (memory hub) or north bridge (North Bridge) are indispensable.
So-called BIOS13 comprises start map data or initial code, store usually/in be built in ROM (read-only memory)/flash memory device.Memory device is a kind of input/output device, and processor 11 needs to capture BIOS13 so that 01 start of regional mainboard on memory device through system chipset 12.In the present invention, system chipset 12 operates between processor and BIOS as same bridge interface.In addition, system chipset 12 is an I/O center (I/O hub) between processor 11 and input/output device (not shown).
System's input/output bus 40, for example: (as: PCI, PCI-X PCI-E), connect main frame field 10 in input/output device to the bus of LPC or PCI basis (PCI-based).System's input/output bus 40 allows BIOS13 to write to check data (BIOS checkpoint information) specific I/O address, for example 0x0080 (or Port80) on it again.In the enforcement of reality, but system's input/output bus 40 connected system chipset 12 and BIOS13.
Remote monitor module 50 mainly comprises baseboard management controller (BMC) 51, one or more event monitor 52 and code translator 53.
Baseboard management controller 51 is the district management controller of tool firmware, be connected with main frame field 10 and telemanagement main frame with circuit, transmit event signals and check data signals, and see through the ability that the telemanagement link provides telemanagement main frame Long-distance Control/supervision.Basically, baseboard management controller 51 can be embodied as and be set at regional mainboard or the last reserved area Management Controller of system management subcard (SMDC), or the district management controller of the centralization of multizone mainboard, systemic hierarchial.Baseboard management controller 51 can see through with the communication link of IPMI (IPMI) compatibility and be connected with the main frame field, comprises System Management Bus (SMBus), serial port (Serial Port link), network interface link or system's input/output bus.
Event monitor 52 also links with circuit and main frame field 10 and baseboard management controller 51, detecting corresponding to during the system initialization process from the specific initialization event in main frame field 10, for example: the state signal of the release of resetting, first BIOS acquisition or the like, and transmit event signals S eTo baseboard management controller 51.See also Fig. 2 A, in the present invention's embodiment, event monitor 52 mainly comprises synchronizer 521, status checker 522 and incident latch unit 523.
Synchronizer 521 receives and the synchronized monitored state signal of system sequence S mAnd be sent to status checker 522.Monitored state signal S mCan be provided by system hardware element, system's input/output bus or Status Monitor (not shown).Status checker 522 is connected with synchronizer 521 and incident latch unit 523, confirms synchronous state signal S mWhether be positioned at the voltage quasi position (voltage level) of a setting, incident latch unit 523 breech locks also keep event signals S eBe positioned at a specific voltage quasi position, be resent to baseboard management controller.State three elements on the event monitor 52 and all can reach, but actual utilization depends on the circumstances by circuit with flip-flop.Basically, if signal has had synchronous system sequence, synchronizer 521 is at event monitor 52 and inessential.
Fig. 2 B explanation monitors the concrete instance of the event monitor of first BIOS acquisition.Two signal LPC_FRAME and LPC_RESET are contained in the bus protocol of lpc bus 41, when BIOS13 is captured by processor 11 for the first time, LPC_FRAME is used to indication and " starts bus and carry out (starting bustransaction) ", and the replacement of LPC_RESET indication lpc bus 41.System designer can limit the state of the voltage quasi position of related signal with the decision initialization event.In an embodiment of the present invention, if signal LPC_RESET voltage quasi position is low (LOW) (practical surveillance LPC_FRAME# and LPC_RESET*) for high (HIGH) LPC_FRAME voltage quasi position, the signal of the accurate position of two tool specific voltages will be confirmed by status checker 522, and see through and have or the incident latch unit of a door (OR-gate) and a flip-flop is handled.Compare with the state signal, with the generation of indication particular event whether event signals need be limited in specific voltage quasi position.For system's input/output bus on PCI basis, event monitor 52 still sees through with the lpc bus similar methods and monitors first BIOS acquisition incident.
That is relevant signal and state are decided with embodiment.The system's input/output bus that is utilized on practice and the type of System on Chip/SoC will give different definition to the signal state of initialization event.Even initialization event also may be different.For example certain nVIDIA chip (as: CK804, MCP155) can be taken initialization information from some specific BIOS before the initialization event of first BIOS acquisition.Moreover, identical signal will be used to different monitor tasks, for example: if system's input/output bus is the PCI basis, the initialization event of the initialization event of " startup ROM (ROM Strapping) " and " first BIOS acquisition " may see through detecting PCI_RESET* (LOW) signal and be monitored together.
Code translator 53 connected system input/output bus 40 and decipher write to the inspection data on the specific I/O address Port80 on system's input/output bus 40.The inspection data of decipher will be as checking data signals S sBe sent to baseboard management controller 51.Fig. 2 C is the example of code translator 53.In Fig. 2, the execution (transactions) of bus interface surveillance input/output bus.Comparer relatively current address is checked the destination address of data with storing BIOS, afterwards and produce the data latching enable signal.Bus interface also produces the effectively signal of (data valid) of data based on the bus protocol of system's input/output bus 40.If (current data are to check data, can are an incident by incident latch unit 52 breech locks.) except that telemanagement, code translator 53 still can be connected to an indicator 31 to show inspection data thereon.
At last, see through baseboard management controller 51, the telemanagement main frame can be taken the setting event data of system initialization and the inspection data of BIOS checkpoint information.Event monitor of the present invention allows the user to monitor any required initialization event.
See also Fig. 3.In actual applications, baseboard management controller 51 has limited general input and output (GPIO, General Purpose Input/Output) pin, to receive event signals S eWith inspection data signals S c, but still may be not enough to receive whole signals.A simple method is an external general input-output unit 54 to be installed give event signals S so that enough general input and output pins to be provided eWith inspection data signals S c, for example a general input and output expander (GPIO expender) or a tool residual flux are with the controller of input and output pins.With baseboard management controller 51 and general input-output unit 54, be connected to the System Management Bus 42 that extends from the system chipset 12 in main frame field 10 then.Event signals S cWith inspection data signals S cBe transferred into general input-output unit 54 subsequently, and take through System Management Bus 42 by baseboard management controller 51.
See also Fig. 4, another is connected between baseboard management controller 51, event monitor 52 and the code translator 53 for a bus multiplexer (MUX) 55 that adds is installed at the settling mode of the limited general input and output pin of baseboard management controller.Event signals S eWith inspection data signals S cTo be transferred into bus multiplexer 55.Bus multiplexer 55 will be according to the selection signal S from baseboard management controller 51 then s, from event signals S eWith inspection data signals S cThe middle type signal of selecting is sent to baseboard management controller 51.Select signal S sCan be transmitted by baseboard management controller 51 according to the order of telemanagement main frame or the selection logic in the baseboard management controller 51.
Fig. 5 is the detailed diagram of the practical application of Fig. 4 zone mainboard 01.In remote monitor module 50, include 4 event monitors that add 52.One is connected in system chipset 12, is connected in power supply unit 15; Both are connected in lpc bus 41 and Status Monitor 16 in addition.System chipset 12 can provide from power rectifier (not shown) or power supply unit 15 they " power initiation order (power-upsequence) " state signals.About status checker 16, general hardware check controller can be used to surveillance temperature and fan information signal usually.Some power supply unit that disposes a power-supply controller of electric can produce one or more state signals.And as previously mentioned, some state signal for example: " bus reset discharge (bus reset release) " has been the some of the bus protocol of system's input/output bus 40.
Therefore, the event monitor 52 different conditions signal that can be collected in system's initial procedure gives baseboard management controller 51.Add the inspection data signals from code translator 53, remote monitor module 51 can monitor almost that in the system initialization process each betides the detailed incident of regional mainboard 01 immediately.Baseboard management controller 51 can be connected to network interface 17, for example: a tool network interface controller (NIC, Network InterfaceController) and the LAN of LAN PORT COM (LAN) module, transmit above-mentioned signal to the telemanagement main frame to see through telemanagement link (as LAN).Certainly, in the non-BIOS of system initialization process (non-BIOS) incident, the code translator in the remote monitor module can be omitted.
Though technology contents of the present invention discloses as above with preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this skill person, does a little change and retouching in the spirit that does not break away from the present invention, all should be covered by in the present invention's the category.
