Performing select input/output requests while in protected memory states

A computer program product, comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable by a processor, executable by the processor, or readable and executable by the processor, to cause the processor to:

• receive an indication that a memory has entered a protected state;
• receive input/output (I/O) requests intended for target locations in the memory;
• determine whether the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, by:
• comparing the target locations with memory blocks that have been listed in a buffer as having a sufficient number of invalid pages, and
• in response to identifying an overlap between one or more of the target locations and the memory blocks listed in the buffer, concluding the one or more of the target locations are permitted to perform I/O requests;
• in response to determining one or more of the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, determine whether the corresponding target locations are permitted to perform the one or more of the I/O requests while the memory is in the protected state by:
• using a trained machine learning model to:
• inspect blocks in the memory at the target locations,
• identify invalid ones of the blocks at the target locations, and
• determine an amount of available space the one or more of the I/O requests will produce in the blocks at the target locations as a result of being performed;
• and
• in response to determining one or more of the target locations are not permitted to perform I/O requests while the memory is in the protected state, deny the respective I/O requests.

A system, comprising:

• memory;
• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• receive an indication that the memory has entered a protected state;
• receive input/output (I/O) requests intended for target locations in the memory;
• determine whether the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, by:
• comparing the target locations with memory blocks that have been listed in a buffer as having a sufficient number of invalid pages, and
• in response to identifying an overlap between one or more of the target locations and the memory blocks listed in the buffer, concluding the one or more of the target locations are permitted to perform I/O requests;
• in response to determining one or more of the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, determine whether the corresponding target locations are permitted to perform the one or more of the I/O requests while the memory is in the protected state by:
• using a trained machine learning model to:
• inspect blocks in the memory at the target locations, identify invalid ones of the blocks at the target locations, and
• determine an amount of available space the one or more of the I/O requests will produce in the blocks at the target locations as a result of being performed;
• and
• in response to determining one or more of the target locations are not permitted to perform I/O requests while the memory is in the protected state, deny the respective I/O requests.

A computer-implemented method, comprising:

• receiving an indication that a memory has entered a write protect state;
• receiving input/output (I/O) requests from sources, the I/O requests intended for target locations in the memory;
• determining whether the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, by:
• comparing the target locations with memory blocks that have been listed in a buffer as having a sufficient number of invalid pages,
• identifying an overlap between one or more of the target locations and the memory blocks listed in the buffer, and
• in response to identifying the overlap between one or more of the target locations and the memory blocks listed in the buffer, concluding the one or more of the target locations are permitted to perform I/O requests;
• in response to determining one or more of the I/O requests are received from sources that are not permitted to initiate I/O requests while the memory is in the protected state, denying the respective one or more of the received I/O requests;
• in response to determining one or more of the I/O requests are received from sources that are permitted to initiate I/O requests while the memory is in the protected state, determining whether the corresponding target locations are permitted to perform the one or more of the I/O requests while the memory is in the protected state by:
• using a trained machine learning model to:
• evaluate use data associated with how physical blocks in the memory are being used at the target locations in real-time,
• identify invalid ones of the physical blocks at the target locations, and determine an amount of available space the one or more of the I/O requests will produce in the physical blocks at the target locations as a result of being performed;
• and
• in response to determining the corresponding target locations are permitted to perform the one or more of the I/O requests while the memory is in the protected state, causing the respective one or more of the received I/O requests to be performed at the corresponding target locations.
