* x86/ras: Flip the TSC-adding logicBorislav Petkov2017-01-243-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add the TSC value to the MCE record only when the MCE being logged is precise, i.e., it is logged as an exception or an MCE-related interrupt. So it doesn't look particularly easy to do without touching/changing a bunch of places. That's why I'm trying tricks first. For example, the mce-apei.c case I'm addressing by setting ->tsc only for errors of panic severity. The idea there is, that, panic errors will have raised an #MC and not polled. And then instead of propagating a flag to mce_setup(), it seems easier/less code to set ->tsc depending on the call sites, i.e., are we polling or are we preparing an MCE record in an exception handler/thresholding interrupt.

* x86/ras/amd: Make sysfs names of banks more user-friendlyYazen Ghannam2017-01-242-3/+8
| | | | | | | | | | | | | | | | | | | | | Currently, we append the MCA_IPID[InstanceId] to the bank name to create the sysfs filename. The InstanceId field uniquely identifies a bank instance but it doesn't look very nice for most banks. Replace the InstanceId with a simpler, ascending (0, 1, ..) value. Only use this in the sysfs name when there is more than 1 instance. Otherwise, just use the bank's name as the sysfs name.

* x86/ras/therm_throt: Do not log a fake MCE for thermal eventsBorislav Petkov2017-01-243-50/+11
| | | | | | | | | | | | | | | | | | | | | | | We log a fake bank 128 MCE to note that we're handling a CPU thermal event. However, this confuses people into thinking that their hardware generates MCEs. Hijacking MCA for logging thermal events is a gross misuse anyway and it shouldn't have been done in the first place. And besides we have other means for dealing with thermal events which are much more suitable. So let's kill the MCE logging part.

It behaves as if VT were switched, but the graphics remain frozen. Actually the keyboard works, so I could switch back to VT7 again. I tried to track down the problem, and encountered a long story until we reach to this error: - The machine is booted with video=1366x768 option (the distro installer seems to add it as default). - Recently, drm_helper_probe_single_connector_modes() deals with cmdline modes, and it tries to create a new mode when no matching mode is found. - The drm_mode_create_from_cmdline_mode() creates a mode based on either CVT of GFT according to the given cmdline mode; in our case, it's 1366x768. - Since both CVT and GFT can't express the width 1366 due to alignment, the resultant mode becomes 1368x768, slightly larger than the given size. - Later on, the atomic commit is performed, and in drm_atomic_check_only(), the size of each plane is checked. - The size check of 1366x768 fails due to the above, and eventually the whole VT switch fails. Back in the history, we've had a manual fix-up of 1368x768 in various places via c09dedb7a50e ("drm/edid: Add a workaround for 1366x768 HD panel"), but they have been all in drm_edid.c at probing the modes from EDID. For addressing the problem above, we need a similar hack to the mode newly created from cmdline, manually adjusting the width when the expected size is 1366 while we get 1368 instead.

This delay should not be needed, but Optimus/nouveau will fail in a mysterious way if the delayed event is handled as soon as possible like it is done in drm_helper_probe_single_connector_modes() in case the poll was enabled before. Reverting 339fd36238dd would give back the 10 sec (!) delay to handle the delayed event. Adding 1sec delay to the poll_work is enough to work around the issue in Optimus setups and gives shorter response on handling the initial delayed event.
