CXL Type 3 device implements a threshold for corrected errors as described in CXL 3.1 specification section 8.2.9.2.1.2 and 8.2.9.9.11.3. Device can set the threshold field in the DRAM event descriptor when it detects corrected errors that meet or exceed the threshold value. This patch is intended to offline pages for corrected memory errors when the device sets the threshold in the DRAM event descriptor. This helps prevent corrected errors from becoming uncorrected. Record the hpa for given dpa, then do pageoffline for hpa when corrected errors threshold is set. Signed-off-by: Srinivasulu Thanneeru <[email protected]>
