Memory errors could be printed with incorrect row values since the DIMM
size has outgrown the 16 bit row field in the CPER structure. UEFI
Specification Version 2.8 has increased the size of row by allowing it to
use the first 2 bits from a previously reserved space within the structure.

When needed, add the extension bits to the row value printed.

Based on UEFI 2.8 Table 299. Memory Error Record

Unless any of the EDAC folks object, I will take this as a fix via the EFI tree.

Thanks,

This is not very readable.

> +		row_extended |= mem->row;
> +		n += scnprintf(msg + n, len - n, "row: %d ", row_extended);
> +	}

Both those hunks contain duplicated code which kinda wants to be an
inline function in cper.h which returns row_extended and gets called by
both sites. And then the call site can look very simple:

        if (mem_err->validation_bits & CPER_MEM_VALID_ROW)
                row = mem_err->row;

        /* add row extension */
        row |= cper_get_mem_extension();

        p += sprintf(p, "row:%d ", row);

with

static inline u32 cper_get_mem_extension(void)
{
	if (!(mem_err->validation_bits & CPER_MEM_VALID_ROW_EXT))
		return 0;

	return (mem_err->extended & CPER_MEM_EXT_ROW_MASK) << CPER_MEM_EXT_ROW_SHIFT;
}

Something along those lines...

Thx.

Yes, I am working on a resubmit. The updated patch will be resubmitted in a series of patches that include other updates to the cper memory record.

Thanks,

This is not very readable.

Both those hunks contain duplicated code which kinda wants to be an inline function in cper.h which returns row_extended and gets called by both sites. And then the call site can look very simple:

        if (mem_err->validation_bits & CPER_MEM_VALID_ROW)
                row = mem_err->row;

        /* add row extension */
        row |= cper_get_mem_extension();

        p += sprintf(p, "row:%d ", row);

with

static inline u32 cper_get_mem_extension(void) {
	if (!(mem_err->validation_bits & CPER_MEM_VALID_ROW_EXT))
		return 0;

	return (mem_err->extended & CPER_MEM_EXT_ROW_MASK) << CPER_MEM_EXT_ROW_SHIFT; }

Something along those lines...

Thx.
