Detailed Description
The core of the application is to provide a setting method, a setting device, a server and a computer readable storage medium for MMIO resources, which enable MMIO resource setting to break through a larger setting range, not to be limited in the fixed range, avoid machine downtime caused by MMIO resource exhaustion and improve the stability of the server through a displayed custom setting item and a plurality of sequentially-increased fixed setting items.
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the related art, the IIO module of the corresponding CPU may be divided into a plurality of Stack units, and the Stack numbers of different CPU architecture platforms may be different. The current BIOS code and RC code may set a plurality of fixed settings with different sizes for a High-end MMIO Base (MMIO HighBase) of the device, such as 512G/1T/2T … … T (including but not limited to), and may set a plurality of fixed settings for each Stack to be allocated with resources, such as 1G/4G … … up to 1024G, for each allocated High-end MMIO High Granularity Size and MMIO HighBase (MMIO High Granularity Size), and provide the setting items for the user to select corresponding MMIOHigh Granularity Size and MMIO HighBase in the BIOS setting interface. However, when a computer is connected with a plurality of GPU devices, especially when the devices are connected to the same Stack, the situation that the resource demand exceeds the current maximum setting quantity 1024G can occur, so that the problems of insufficient quantity identification of GPU devices, incapability of normal operation of some PCIE devices including GPUs and the like, insufficient machine error prompting resources, no further continuous starting due to downtime and the like are caused, and the stability of the system is reduced.
Therefore, the MMIO resource setting method provided by the application enables MMIO resource setting to break through a larger setting range, not be limited in a fixed range, avoids machine downtime caused by MMIO resource exhaustion, and improves the stability of a server through the displayed custom setting items and a plurality of fixed setting items which are sequentially increased.
The following describes, by an embodiment, a method for setting MMIO resources provided in the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for setting MMIO resources according to an embodiment of the present application.
In this embodiment, the method may include:
s101, displaying MMIO High Granularity Size and MMIO High Base setting items; the setting items comprise a custom setting item and a plurality of fixed setting items which are sequentially increased;
this step is intended to show the MMIO High Granularity Size and MMIO High Base settings. The setting items comprise a custom setting item and a plurality of fixed setting items which are sequentially increased.
Wherein the custom settings are for the user to manually enter MMIO High Granularity Size and MMIOHigh Base data. In the related art, however, a few limited fixed setting items are generally given. When a plurality of devices commonly require a large MMIO High Granularity Size and MMIO High Base, a large MMIO High Granularity Size and MMIO High Base are required, and the related art is limited in that the granularity value cannot be broken. In the running process of the system, the problem that the requirements of equipment on MMIO resources exceed the set resource size, so that errors, downtime and the like occur is caused.
Therefore, the custom setting item is displayed in the step so as to break through the limitation of MMIO resources in the prior art and avoid the problems of downtime and the like caused by the limitation of MMIO resources.
Further, in order to improve the setting efficiency, the sum of MMIO High Granularity Size and MMIOHigh Base may be displayed in the setting option as the sum of MMIO allocation amounts as a setting item, so that MMIO High Granularity Size and MMIO High Base are directly set by the sum of MMIO allocation amounts, thereby improving the setting efficiency.
S102, receiving a setting instruction of a setting item;
on the basis of S101, this step is intended to receive a setting instruction of a setting item. That is, on the basis of displaying the respective setting items, the user or technician selects or inputs so as to transmit the corresponding setting items, and a setting instruction of the setting item is received in this step. Wherein the set instruction contains a specific set granularity value.
Further, the step may include:
receiving a setting instruction of a setting item through a BIOS setting interface, and carrying out corresponding processing according to the setting instruction.
It can be seen that in this alternative, the setting instruction is received mainly through the BIOS setting interface, and corresponding processing is performed according to the setting instruction. In addition, the setting instruction may also be acquired by a device in the same network, or received through an instruction line.
S103, judging whether the sum of MMIO resource amounts of all stacks and the sum of MMIO High Base are smaller than a threshold value;
on the basis of S102, this step is aimed at determining whether the sum of the MMIOH (Memory Mapped I/O High, memory space Mapped maximum) resource amounts of all stacks and the sum of MMIO High Base are smaller than a threshold. Wherein the threshold value refers to the physical limit of the largest MMIO resource that can be set in the computer system. It can be seen that in this step, it is mainly determined whether the granularity value in the setting instruction is smaller than the threshold value, so as to avoid exceeding the physical limit.
That is, the related art limits the size of the MMIO resources to be within 1024G, but in a general system, the actual MMIO resources may exceed 1024G without affecting the system, and the limitation of 1024G is only the software limitation in the system. Where 1024G is a limitation, the limitation may be a different value in different practical systems, and is not specifically limited herein.
Based on the above description, the present embodiment simply determines whether the granularity value exceeds the physical limit by displaying the respective setting items without limiting MMIO High GranularitySize and MMIO High Base, expands the setting ranges of MMIO HighGranularity Size and MMIO High Base, and maintains normal use.
Further, the embodiment may further include:
acquiring the numerical value of an EAX register through a CPUID command; and analyzing the numerical value of the EAX register to obtain a threshold value.
It can be seen that the manner in which the threshold is obtained is mainly described in this alternative. In the alternative scheme, the numerical value of the EAX register is obtained through a CPUID command; and analyzing the numerical value of the EAX register to obtain a threshold value. That is, the corresponding threshold value is queried from the system and set.
And S104, if so, setting MMIO granularity values, stack resource Base values, limit values and corresponding registers of all stacks according to the setting instruction.
On the basis of S103, this step aims to set MMIO granularity values, stack resource Base values, limit values and corresponding registers of all stacks according to the set instruction when the granularity value corresponding to the instruction is smaller than the threshold value. That is, in the case where it is determined that there is no problem in the granularity value in the set instruction, the MMIO granularity value, stack resource Base value, limit value, and corresponding registers are set so as to implement an unlimited MMIO setting process.
Wherein the MMIO granularity value is a unit of allocated resource quantity, is not equal to the last actually allocated resource quantity, and is finally reflected to the start (namely the Stack resource Base value) and the upper Limit setting (Limit value) of the Stack resource except the setting and processing of granularity value, and comprises related registers
Further, the embodiment may further include:
when the MMIO resource quantity of any Stack connecting device is larger than the preset quantity, dynamically and incrementally adjusting MMIO HighGranularity Size and MMIO High Base of Stack; the configuration data for each Stack is updated.
It can be seen that this alternative is mainly to explain how to make dynamic adjustments. In the alternative scheme, when the MMIO resource quantity of any Stack connecting device is larger than a preset quantity, dynamic increment adjustment is carried out on MMIO High GranularitySize and MMIO High Base of Stack; the configuration data for each Stack is updated. That is, when the number of devices connected by Stack is continuously increased and is greater than the preset number, dynamic incremental adjustment can be performed on MMIO HighGranularity Size and MMIO High Base of the Stack so as to increase MMIO resources, and finally, the configuration data of each Stack is updated.
Further, the embodiment may further include:
judging whether the sum of MMIO resources and MMIO High Base of all Stacks is larger than the upper limit value of physical resources;
if so, the MMIO High Base value is scaled.
Therefore, in the alternative scheme, whether the sum of MMIO resources and MMIO High Base of all Stacks is larger than the upper limit value of physical resources is mainly judged; if so, the MMIO High Base value is scaled. That is, when the MMIO resources of Stack exceeds the physical resource upper limit value, the MMIO High Base value is scaled so as to reduce the starting height of MMIO, and the total MMIO resources are reduced to avoid exceeding the MMIO resource upper limit. The demand of any one or any some resources for Stack resources can be reduced, so that the usage of Stack resources is reduced. The magnitude of the decrease may be adjusted according to the actual situation, and is not particularly limited herein.
Further, the embodiment may further include:
and modifying the fault reporting function and the downtime function of the MMIO upper limit according to the threshold value.
Therefore, in the alternative scheme, the error reporting function and the downtime function of the MMIO upper limit are mainly modified, so that the error reporting and the downtime are avoided directly after MMIO resource allocation exceeds the limit, and the normal operation of the system is prevented from being influenced. Furthermore, in the alternative, the reduction processing can be performed under the condition that the sufficient use of each Stack resource amount is ensured.
In summary, according to the embodiment, through the displayed custom setting item and the plurality of sequentially-increased fixed setting items, the MMIO resource setting can break through a larger setting range, but is not limited in a fixed range, so that machine downtime caused by MMIO resource exhaustion is avoided, and the stability of the server is improved.
The following describes a method for setting MMIO resources according to the present application through a specific embodiment.
In the related art, although MMIO High Granularity Size in the code is set up to only 1024G at maximum, and there is a check in the code to see if this setting exceeds 1024G, if it exceeds the processing of reporting a fault and making the machine down. But in practice the MMIO High Granularity Size setting may exceed 1024G. And the amount of MMIO resources that may be allocated to each Stack is not the same.
Based on this, in this embodiment, the setting items are added to MMIO High Granularity Size according to actual needs, and the existing code processing logic is that each setting item is in a 4-fold relationship with the last setting item of the neighboring, for example, the next setting item of 1024G is 4096G, and a unique ID value is assigned to each setting item;
the processing of MMIO High Granularity Size setting items in specific codes can be divided into two types, namely a fixed setting item which continues 4 times of the relation in the existing code logic, and a custom setting item with custom value can be obtained by performing special processing according to the unique ID of each setting item;
when more PCIE devices such as GPU are connected to the machine, especially when many of the devices are from one CPUStack/IIO Port, the prior maximum MMIO 1024G is not enough, so that the problem of resource shortage is caused, the MMIO HighGranularity Size setting item is set as a custom setting item. In actual operation, more MMIO resources are allocated to all CPUStack/IIO ports, and the specific quantity is equal to the newly added setting item, so that the problem of resource shortage can be solved.
Further, in order to solve the problem that the current code is MMIO with the same capacity allocated to each CPU Stack, the current method is improved, when PCIE devices such as too many GPUs are connected to a machine, especially when many of the devices come from one CPU Stack/IIO Port, the previous maximum MMIO quantity 1024G is not enough, and therefore resources are lack, the one or several stacks lacking resources can be dynamically allocated to more resources. And updating the Base and Limit data of each Stack resource according to the changed configuration condition, recording the Base and Limit registers of the resources under the track in the PCIE configuration space of the Root port bridge corresponding to each Stack, and updating the current improved setting condition value to the registers according to the PCIE specification definition mode.
Taking the Intel Whitley platform as an example, the maximum upper limit value can be obtained by acquiring and analyzing the obtained EAX register value through a corresponding CPUID command; on the other hand, some PCIE devices have their own MMIO resource range requirements, for example, a maximum of the MMIO resource range requirements cannot exceed an upper limit;
in addition, the total MMIO amount allocated by the BIOS to the PCI/PCIE device is increased in this embodiment, which may cause challenges to the upper limit values of the two cases;
therefore, the setting of MMIO High Base can be adjusted in a reduced amount, and MMIO addresses of all PCIE devices can be adjusted in a low way, so that the purpose of not exceeding the MMIO upper limit supported by the CPU is achieved. It should also be noted that this value needs to meet Intel's related design and implementation requirements, such as including and not limited to the need to ensure that it cannot be less than the total amount of memory available on the machine; when no suitable MMIO High Base setting item exists, the setting item of a required value is newly added to the MMIO High Base setting item according to the current implementation logic; on the other hand, the hardware can adjust the CPU Stack connected with the PCIE equipment with special requirements, for example, when the equipment has the requirement of the upper limit of resources, the equipment is preferentially connected to the low Stack port of the CPU0, or on the software level, the original method of sequentially distributing resources to each Stack of each CPU is broken, resources are distributed to stacks connected with equipment needing low MMIO according to the requirement, then resources are distributed to stacks connected with equipment needing high MMIO, and variables and registers for counting the upper limit and the lower limit of each Stack and each CPU and each related Bridge resource are processed, so that the effect of meeting the requirements of the upper limit and the lower limit of MMIO of the equipment is achieved.
After the resource allocation problem is solved, deleting or adjusting the existing resource checking processing mechanism which is not consistent with the actual design in the code to make the resource checking processing mechanism consistent with the actual design, including and not limited to removing the error reporting and downtime processing of the allocation upper limit 1024G of MMIO of each Stack in the code;
therefore, the upper limit of MMIO resources supported by the CPU or the Stack below the CPU is recognized in advance, along with updating of PCIE equipment, MMIO resource requirements required by the equipment are larger and larger, and when the number of the equipment is enough, the development trend of conflict in two aspects is caused, improvement and solution are provided, the problems that equipment cannot be completely recognized, cannot work normally, and is insufficient in machine report resources of a server where the equipment is located and the like caused by insufficient resources of the PCIE equipment are solved, the conventional MMIO resource allocation processing scheme of Intel is improved, the potential misleading influence of Intel codes on related designs is clarified, and the related problems of Intel code processing and AI model design processing (GPU equipment containing a plurality of multi-resource requirements) are processed.
