Hi Huang, thanks for the patch. -----Original Message----- > For DISKDUMP case, we can get VA_BITS_ACTUAL from CONFIG_ARM64_VA_BITS. I could not understand this, there is a case where CONFIG_ARM64_VA_BITS is different from VA_BITS_ACTUAL and why is this only for DISKDUMP case? If the patch intends to guess the value of VA_BITS_ACTUAL to be the same as CONFIG_ARM64_VA_BITS when no NUMBER(TCR_EL1_T1SZ), I think that DISKDUMP check is not needed and it would be better to write such a commit log and a comment e.g. "/* guess */" on the else if block.
