Hi Tony, > Still untested ... Qiuxu, can you try this out please. Tested this patch (with the updated skx_edac.c using the new wrapped interfaces) on Skylake (2 sockets) + BIOS with ADXL DSM support: Decoding by this patch worked well (e.g. the decoded result was identical to the decoded result by original skx_edac driver for DDR4 memory for the same addresses). Thanks! -Qiuxu
