receive an error reporting message from a component of the components of the processor, the error reporting message corresponding to an error detected by the component; and log the error as an entry in the at least one centralized error queue based on an error type of the error. ## Claims ### Claim 1 An apparatus comprising: a processor comprising a systems interface hosting an error aggregator, wherein the processor is to: host at least one centralized error queue in the error aggregator, the at least one centralized error queue is to store error logs for errors detected by components of the processor; receive an error reporting message from a component of the components of the processor, the error reporting message corresponding to an error detected by the component; and log the error as an entry in the at least one centralized error queue based on an error type of the error. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the processor is further to identify, from the error reporting message, the error type of the error comprising one of a correctable error, an uncorrectable contained error, or an uncorrectable uncontained error, and wherein the at least one centralized error queue comprises one or more of a correctable centralized error queue, a centralized error queue, or an uncorrectable centralized error queue to store the errors of respective ones of the error type. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the error reporting message is in an uncorrectable error log format responsive to the error type comprising one of the uncorrectable contained error or the uncorrectable uncontained error. ### Claim 4 (depends on 2) The apparatus of claim 2, wherein the error reporting message is in a correctable error log format responsive to the error type comprising the correctable error. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the processor is further to update at least one of a centralized log read control register, a centralized log status register, or a centralized log control register to reflect an updated state of the at least one centralized error queue that logged the error. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein a driver is to utilize the centralized log read control register, the centralized log status register, and the centralized log control register to read entries of the at least one centralized error queue and to clear the entries of the at least one centralized error queue. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the at least one centralized error queue maintains entries across a warm reset of the processor. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the at least one centralized error queue is written to utilizing a quad-word write having an upper 32 bits carrying an identifier (ID) of a unit performing the quad-word write, and a lower 32 bits carrying data of the quad-word write. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the processor comprises a graphics processing unit (GPU). ### Claim 10 A method comprising: hosting, by a processing device comprising a systems interface hosting an error aggregator, at least one centralized error queue in the error aggregator, the at least one centralized error queue to store error logs for errors detected by components of the processing device; receiving, by the processing device, an error reporting message from a component of the components of the processing device, the error reporting message corresponding to an error detected by the component; and logging, by the processing device, the error as an entry in the at least one centralized error queue based on an error type of the error. ### Claim 11 (depends on 10) The method of claim 10, further comprising identifying, from the error reporting message, the error type of the error comprising one of a correctable error, an uncorrectable contained error, or an uncorrectable uncontained error, and wherein the at least one centralized error queue comprises one or more of a correctable centralized error queue, an uncorrectable local centralized error queue, or an uncorrectable global centralized error queue is to store the errors of respective ones of the error type. ### Claim 12 (depends on 11) The method of claim 11, wherein the error reporting message is in an uncorrectable error log format responsive to the error type comprising one of the uncorrectable contained error or the uncorrectable uncontained error. ### Claim 13 (depends on 11) The method of claim 11, wherein the error reporting message is in a correctable error log format responsive to the error type comprising the correctable error. ### Claim 14 (depends on 10) The method of claim 10, further comprising updating at least one of a centralized log read control register, a centralized log status register, or a centralized log control register to reflect an updated state of the at least one centralized error queue that logged the error. ### Claim 15 (depends on 14) The method of claim 14, wherein a driver is to utilize the centralized log read control register, the centralized log status register, and the centralized log control register to read entries of the at least one centralized error queue and to clear the entries of the at least one centralized error queue. ### Claim 16 A non-transitory computer-readable medium having instructions stored thereon, which when executed by one or more processors, cause the one or more processors to: host, by a processing device of the one or more processors comprising a systems interface hosting an error aggregator, at least one centralized error queue in the error aggregator, the at least one centralized error queue is to store error logs for errors detected by components of the processing device;
