UFS devices typically support a command queue mechanism, with the maximum queue depth that UFS devices have referring to the maximum number of commands that UFS devices can simultaneously receive and process. Under the command queue mechanism, the test host may place multiple asynchronous commands into the queue and the UFS device may process the commands in the order of the queue.

If the depth of the command queue supported by the test host is far less than the maximum queue depth of the UFS device, the processing capacity of the UFS device cannot be fully utilized, resulting in the idle of the UFS device and prolonging the test period, while if the depth of the command queue supported by the test host is far more than the command queue depth of the UFS device, the command queue of the UFS device is filled, and the redundant commands need to wait for the idle queue, resulting in the accumulation of commands and also prolonging the test period.

Specifically, the preset command sending modes include two different modes, and a fixed depth mode and a random depth mode are defined when the operation command sent by the test host is received from the UFS device. The depth of the command queue to be processed in the UFS device is fixed in the fixed depth mode, and the depth of the command queue to be processed in the UFS device is variable in the random depth mode.
In the process of carrying out system test on the UFS equipment by utilizing a test host, firstly, generating a plurality of operation commands of different types, secondly, determining a first queue depth according to a preset command transmission mode, asynchronously transmitting the operation commands of the first queue depth to the UFS equipment so that the UFS equipment stores the operation commands in a command queue form and processes the operation commands according to a queue sequence, and returning a response after each operation command is completed, wherein the preset command transmission mode comprises a fixed depth mode and a random depth mode, then, receiving response responses returned by the UFS equipment, then, determining a second queue depth of the operation commands transmitted next according to the preset command transmission mode and the counted number of the received response responses reflects the command processing condition of the current UFS equipment, and finally, transmitting the operation commands of the second queue depth to the UFS equipment, continuously storing the operation commands in the command queue form and processing the operation commands according to the queue sequence, until all the operation commands are transmitted, and the system test efficiency of the UFS equipment is fully shortened, and the system test capability of the UFS equipment is fully tested by utilizing the system test equipment is improved.

Step S110 is further described according to some embodiments of the present application, step S110 generating a plurality of different types of operation commands including, but not limited to, steps S111 through S114.
Step S111, generating a random number with a logic address, a block size and a value in the range of 0 to 100%.
Step S112, determining a corresponding operation type according to a numerical value interval where the random number is located, wherein the operation type comprises a read operation, a write operation and an erase operation.
And step 113, performing command generation processing according to the logical address, the block size and the operation type to obtain an operation command, wherein the type of the operation command is determined by the operation type.
Step S114, repeating the command generating process for a plurality of times to obtain a plurality of operation commands, wherein the operation commands comprise a read command, a write command and an erase command.
Specifically, step S111 is further described. The logical addresses are generated in two ways, one of which is to randomly generate the logical addresses within a specified address range and the other is to generate the logical addresses by a random function within a range determined by the capacity length of the entire UFS device. The block size may be specified by pre-configuration information or may be randomly generated in the range of 1 to 128.
According to some embodiments of the present application, step S112 is further described, wherein step S112 includes determining a corresponding operation type according to a value interval in which the random number is located, including, but not limited to, determining the operation type as a read operation when the random number is greater than or equal to 0 and less than a first threshold, determining the operation type as a write operation when the random number is greater than or equal to the first threshold and less than a second threshold, wherein the second threshold is greater than the first threshold and determining the operation type as an erase operation when the random number is greater than or equal to the second threshold and less than or equal to 100%. And determining the operation type through the interval of the random number so as to indicate the type of the operation command to be generated.
As an example, a specific procedure of determining the operation type from the random number is explained.
Example one determines a first threshold, a second threshold according to a preset sequence (read, write, erase) of command duty cycle, wherein the first threshold is equal to the sum of the incoming percentage of write operations and the second threshold is equal to the sum of the incoming percentage of write operations and the incoming percentage of write operations, i.e. when the preset sequence of command duty cycle is 50% of read operations, 30% of write operations, 20% of erase operations, the preset first threshold is 50% and the second threshold is 80%, and further a value interval is determined based on the first threshold, the second threshold, in particular the value interval comprises a first interval [0, 50%) determined by 0 and the first threshold, a second interval [50%, 80%) determined by the first threshold and the second threshold, and a third interval [80%, 100%) determined by the second threshold and 100%. Generating a random number in a range of 0 to 100%, if the random number is 40%, 40% falls in a first section, judging that the operation type of the operation command to be generated is a read operation, if the random number is 50%, 50% falls in a second section, judging that the operation type of the operation command to be generated is a write operation, and if the random number is 80%, 80% falls in a third section, judging that the operation type of the operation command to be generated is an erase operation.
It will be appreciated that the command duty cycle of the preset sequence (read, write, erase) may be adjusted, and the first threshold and the second threshold may be adjusted, so the present application does not specifically limit the command duty cycle, the first threshold and the second threshold of the preset sequence (read, write, erase).
Through steps S111 to S114, a plurality of operation commands of different types are generated based on the logical address, the block size and the random number, which provides a basis for subsequent system testing of UFS devices.
After step S110 and before step S120, the system testing method for UFS devices according to the embodiment of the present application further includes determining a type of a preset command transmission mode according to the entered mode selection parameter. Specifically, when the mode selection parameter is 0, the preset command transmission mode is determined to be a random depth mode, and when the mode selection parameter is a non-zero positive number, the preset command transmission mode is determined to be a fixed depth mode.
According to some embodiments of the present application, further describing step S120, when the preset command transmission mode is a random depth mode, step S120 includes, but is not limited to, steps S210 to S220, determining the first queue depth according to the preset command transmission mode.
Step S210, obtaining the maximum command queue depth of the UFS equipment according to the random depth mode.
Step S220, determining the maximum command queue depth as the first queue depth.
Specifically, in step S210, the test host obtains the maximum command queue depth of the UFS device, where the maximum command queue depth refers to the maximum number of commands that the UFS device can simultaneously receive and process.
Through steps S210 to S220, the maximum command queue depth of the UFS device is determined as the first queue depth, and a reference is provided for the test host to initially send an operation command.
According to some embodiments of the present application, step S130 is further described, wherein when the preset command transmission mode is a random depth mode, step S130 is to determine a second queue depth of the next transmitted operation command according to the preset command transmission mode and the counted number of received response responses, including but not limited to steps S230 to S250.
Step S230, randomly generating delay time in a preset time range according to the random depth mode.
Step S240, counting the number of response responses returned by the UFS equipment received in the delay time.
Step S250, determining the number of received response responses in the delay time as the second queue depth.
It can be understood that in the random depth mode, the test host randomly generates a delay time, starts timing after sending the operation command of the first queue depth to the UFS device, counts the number of response responses returned by the received UFS device within the delay time, and determines the number of response responses received within the delay time as the second queue depth by counting the number of response responses received to reflect the command processing condition of the current UFS device and indicating that the current UFS device still has the remaining power to process a new operation command.
In the embodiment of the application, through the steps S230 to S250, the second queue depth of the operation instruction to be sent next is adjusted according to the number of the response responses received in the random delay time in the random depth mode, so that the operation command of the second queue depth is conveniently sent to the UFS equipment subsequently, the command processing capacity of the current UFS equipment is fully utilized, the test period for carrying out system test on the UFS equipment is shortened, and the test efficiency is improved.
It can be understood that the embodiment of the application realizes the asynchronous command processing mechanism based on the random depth mode through the steps S210, S220, S230, S240, S250 and S150, and under the asynchronous command processing mechanism based on the random depth mode, the system test is performed on the UFS device, so that the command processing capability of the current UFS device can be fully utilized, the test period for performing the system test on the UFS device can be shortened, and the test efficiency can be improved.
As an example, a specific process flow of an asynchronous command processing mechanism based on a random depth mode provided by an embodiment of the present application is described.
Example two when the maximum command queue depth for the UFS device is 32, the first queue depth is made equal to the maximum command queue depth 32. The test host first sends 32 operation commands to the UFS device. And when 28 response responses are received within 500ms, determining that the second queue depth of the operation command to be transmitted for the second time is 28, and transmitting 28 operation commands for the second time. And when 25 response responses are received within 400ms, determining that the second queue depth of the operation command to be transmitted for the third time is 25, and transmitting 25 operation commands for the third time. And the like, carrying out command sending processing for a plurality of times until the system test is completed. It is understood that the second queue depth of the operation command transmitted in each command transmission process is equal to the number of response responses received within a random delay time after the last command transmission process, except for the first command transmission process. Therefore, the command processing capability of the UFS equipment can be fully utilized, and the test period is shortened.
According to some embodiments of the present application, step S120 is further described, wherein when the preset command transmission mode is a fixed depth mode, step S120 is performed to determine the first queue depth according to the preset command transmission mode, including but not limited to steps S310 to S320.
Step S310, obtaining preset fixed depth according to a fixed depth mode, wherein the fixed depth is smaller than or equal to the maximum command queue depth of the UFS equipment.
Step S320, determining the fixed depth as the first queue depth.
It is understood that the fixed depth is preset, as long as the fixed depth is less than or equal to the maximum command queue depth of the UFS device, the value of the fixed depth is not specifically limited by the present application.
Through steps S310 to S320, a preset fixed depth is determined as a first queue depth, and a reference is provided for the test host to initially send an operation command.
According to some embodiments of the present application, step S130 is further described, wherein when the preset command transmission mode is a fixed depth mode, step S130 is to determine a second queue depth of the next transmitted operation command according to the preset command transmission mode and the counted number of received response responses, including but not limited to steps S330 to S340.
Step S330, according to the fixed depth mode, the number of response responses returned by the UFS equipment received each time is counted in real time.
And step 340, determining the number of response responses returned by the UFS equipment obtained through immediate statistics as a second queue depth, wherein the second queue depth is smaller than or equal to the fixed depth in a fixed depth mode.
It can be understood that in the fixed depth mode, the number of response responses returned by the UFS device received each time, counted by the test host in real time, reflects the command processing condition of the current UFS device, which indicates that the current UFS device still has the remaining power to process a new operation command, and the test host responds in real time, and determines the number of response responses returned by the UFS device obtained in real time as the second queue depth.
Through the steps S330 to S340, in the fixed depth mode, the number of response responses returned by the UFS equipment, which are obtained through statistics, is determined to be the second queue depth according to the response responses returned by the UFS equipment, so that the operation commands of the second queue depth are sent to the UFS equipment, the depth of a command queue storing the operation commands to be processed in the UFS equipment is kept to be the fixed depth, the UFS equipment is enabled to process the operation commands of the fixed depth efficiently and stably, the command processing capability of the current UFS equipment is fully utilized, the test period of system test on the UFS equipment is shortened, and the test efficiency is improved.
It can be understood that the embodiment of the application realizes the asynchronous command processing mechanism based on the fixed depth mode through the steps S310, S320, S330, S340 and S150, and under the asynchronous command processing mechanism based on the fixed depth mode, the system test is performed on the UFS device, so that the command processing capability of the current UFS device can be fully utilized, the test period for performing the system test on the UFS device is shortened, and the test efficiency is improved.
As an example, a specific process flow of an asynchronous command processing mechanism based on a fixed depth mode provided by an embodiment of the present application is described.
In an example III, when the preset parameter of the fixed depth is 8, the first queue depth is equal to the fixed depth of 8, and the test host sends 8 operation commands to the UFS device for the first time. When the test host receives one response, 1 operation command is immediately sent to enable the total number of operation commands to be processed in the UFS equipment to be not more than 8 (namely less than or equal to 8), when the test host receives two response, two operation commands are immediately sent to enable the total number of operation commands to be processed in the UFS equipment to be not more than 8 (namely less than or equal to 8), namely, one operation command is immediately sent to the UFS equipment as long as the response of the UFS equipment is received, and the command processing capacity of the UFS equipment can be fully utilized to shorten the test period.
From examples two and three, it can be appreciated that the asynchronous command processing mechanism based on the random depth mode is different from the asynchronous command processing mechanism based on the fixed depth mode in that in the random depth mode, the same number of operation instructions is sent by counting the number of all response responses received within a random event range, and in the fixed depth mode, the same number of operation instructions is sent immediately as soon as the response responses are received. From the perspective of the timing of transmitting the operation instruction, the random depth mode may be understood as a random delay transmission mode, and the fixed depth mode may be understood as a response transmission mode.
Further describing the system test method for the UFS device according to the embodiment of the present application, step S130 includes, after receiving the response returned by the UFS device, parsing the response to obtain execution status information, and when the execution status information is successful, judging that the response is normal and the operation command is successful, and when the execution status information is unsuccessful, judging that the response is abnormal and the operation command is unsuccessful. If the type of the operation command is a read operation, the original data written into the UFS device and the read data read from the UFS device are required to be compared, if the data are consistent, the read is judged to be correct, and if the data are inconsistent, the read is judged to be incorrect.
Step S150 is further described. It can be understood that the number of the operation commands to be sent by the test host and the specific content for performing the system test are determined by the program recorded in the test host by the upper computer, and when all the operation commands to be sent are processed, and the execution of the UFS device is completed, the system test is judged to be completed.
