| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function doesn't give us the "Node ID" as the function name suggests. Rather, it receives a PCI device as argument, checks the available F3 PCI device IDs in the system and returns the index of the matching Bus/Device IDs. Rename it to amd_pci_dev_to_node_id(). No functional change is introduced.

* | EDAC: Use edac_debugfs_remove_recursive()Tan Xiaojun2015-10-142-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | debugfs_remove() is used to remove a file or a directory from the debugfs filesystem, but mci->debugfs might not empty. This can be triggered by the following sequence: 1) Enable CONFIG_EDAC_DEBUG 2) insmod an EDAC module (like i3000_edac or similar) 3) rmmod this module 4) we can see files remaining under <debugfs_mountpoint>/edac/ like "fake_inject", for example. Removing edac_core then, causes a NULL pointer dereference.

* | EDAC, sb_edac: Fix TAD presence check for sbridge_mci_bind_devs()Seth Jennings2015-09-241-4/+4

The *_mci_bind_devs() functions - except for sbridge_mci_bind_devs() - got a new device presence check in the form of saw_chan_mask. However, sbridge_mci_bind_devs() still uses the NUM_CHANNELS for loop. With the increase in NUM_CHANNELS, this loop fails at index 4 since SB only has 4 TADs. This results in the following error on SB machines: EDAC sbridge: Some needed devices are missing EDAC sbridge: Couldn't find mci handler EDAC sbridge: Couldn't find mci handle This patch adapts the saw_chan_mask logic for sbridge_mci_bind_devs() as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when decoding an MCE, we display 'CE' for a Deferred error, like this: [Hardware Error]: CPU:0 (15:2:0) MC4_STATUS[Over|CE|MiscV|-|AddrV|Deferred|-|UECC]: 0xdc04b00095080813 When the 'UC' bit in the MCx_STATUS register is clear, the error status is either a Corrected error or Deferred error as determined by the 'Deferred' bit. So do not print 'CE' on a deferred error. Refer to AMD Error Scope Hierarchy table in a newer BKDG (example: 49125_15h_Models_30h-3Fh_BKDG.pdf, section "RAS Features").

Tracked this down to the code that assumes that systems with two home agents only have two memory channels on each agent. This is true on 2 sockect ("-EP") machines. But four socket ("-EX") machines have four memory channels on each home agent. The old code would have had problems on two socket systems as it did a shuffling trick to make the internals of the code think that the channels from the first agent were '0' and '1', with the second agent providing '2' and '3'. But the code didn't uniformly convert from {ha,channel} tuples to this internal representation. New code always considers up to eight channels. On a machine with a single home agent these map easily to edac channels 0, 1, 2, 3. On machines with two home agents we map using: edac_channel = 4*ha# + channel So on a -EP machine where each home agent supports only two channels we'll fill in channels 0, 1, 4, 5, and on a -EX machine we use all of 0, 1, 2, 3, 4, 5, 6, 7.
