Yeah, some of messages are no longer emitted for memory-less nodes (NUMA 1
and 3). Your patch set also overhauls the messages.
But, the amount of redundant messages I'm complaining about has actually
increased:
dmesg|grep EDAC|cut -c 16-|sort|uniq -c
256 EDAC MC: UMC0 chip selects:
256 EDAC MC: UMC1 chip selects:
1 EDAC MC: Ver: 3.0.0
128 EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
^ three lines each
64 EDAC amd64: F17h detected (node 0).
64 EDAC amd64: F17h detected (node 1).
64 EDAC amd64: F17h detected (node 2).
64 EDAC amd64: F17h detected (node 3).
512 EDAC amd64: MC: 0: 0MB 1: 0MB
256 EDAC amd64: MC: 2: 0MB 3: 0MB
256 EDAC amd64: MC: 2: 8192MB 3: 0MB
64 EDAC amd64: Node 0: DRAM ECC disabled.
64 EDAC amd64: Node 2: DRAM ECC disabled.
256 EDAC amd64: using x4 syndromes.
(Full dmesg at http://ix.io/1T1o)
While on 5.3-rc5 without the patchset I get:
1 EDAC MC: Ver: 3.0.0
256 EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
^ three lines each
64 EDAC amd64: Node 0: DRAM ECC disabled.
64 EDAC amd64: Node 1: DRAM ECC disabled.
64 EDAC amd64: Node 2: DRAM ECC disabled.
64 EDAC amd64: Node 3: DRAM ECC disabled.
So I wonder if we could deduplicate those.
Meow!
