Huang Ying 152cef40a8 ACPI, APEI, GHES, Error records content based throttle ... printk is used by GHES to report hardware errors. Ratelimit is enforced on the printk to avoid too many hardware error reports in kernel log. Because there may be thousands or even millions of corrected hardware errors during system running. Currently, a simple scheme is used. That is, the total number of hardware error reporting is ratelimited. This may cause some issues in practice. For example, there are two kinds of hardware errors occurred in system. One is corrected memory error, because the fault memory address is accessed frequently, there may be hundreds error report per-second. The other is corrected PCIe AER error, it will be reported once per-second. Because they share one ratelimit control structure, it is highly possible that only memory error is reported. To avoid the above issue, an error record content based throttle algorithm is implemented in the patch. Where after the first successful reporting, all error records that are same are throttled for some time, to let other kinds of error records have the opportunity to be reported. In above example, the memory errors will be throttled for some time, after being printked. Then the PCIe AER error will be printked successfully.
