Ok, I went and did cleanup that version here by flipping the logic
in the tests and thus saving an indentation level. Also, I've added
explicit "return"s in the respective cases in order to follow through
the code more easily. Here's how the whole function looks like now - I
think it is a bit better readable this way. Full patch below:
static void determine_memory_type(struct amd64_pvt *pvt)
{
u32 dram_ctrl, dcsm;
switch (pvt->fam) {
case 0xf:
if (pvt->ext_model >= K8_REV_F)
goto ddr3;
pvt->dram_type = (pvt->dclr0 & BIT(18)) ? MEM_DDR : MEM_RDDR;
return;
case 0x10:
if (pvt->dchr0 & DDR3_MODE)
goto ddr3;
pvt->dram_type = (pvt->dclr0 & BIT(16)) ? MEM_DDR2 : MEM_RDDR2;
return;
case 0x15:
if (pvt->model < 0x60)
goto ddr3;

Subject: [PATCH] amd64_edac: Add F15h M60h support
This patch adds support for ECC error decoding for F15h M60h processor.
Aside from the usual changes, the patch adds support for some new features
in the processor:
- DDR4(unbuffered, registered); LRDIMM DDR3 support
- relevant debug messages have been modified/added to report these
memory types
- new dbam_to_cs mappers
- if (F15h M60h && LRDIMM); we need a 'multiplier' value to find
cs_size. This multiplier value is obtained from the per-dimm
DCSM register. So, change the interface to accept a 'cs_mask_nr'
value to facilitate this calculation
- switch-casing determine_memory_type()
- done to cleanse the function of too many if-else statements
and improve readability
- This is now called early in read_mc_regs() to cache dram_type
Misc cleanup:
- amd64_pci_table[] is condensed by using PCI_VDEVICE macro.
Testing details:
Tested the patch by injecting 'ECC' type errors using mce_amd_inj
and error decoding works fine.
