similar to: [PATCH v2 2/2] x86/mce: Use MCG_CAP MSR to find out number of banks on AMD

Currently number of error reporting register banks is hardcoded to 6 on AMD processors. This may break in virtualized scenarios when a hypervisor prefers to report fewer banks that the physical HW provides. Since number of supported banks is reported in MSR_IA32_MCG_CAP[7:0] that''s what we should use. Signed-off-by: Boris Ostrovsky <boris.ostrovsky@oracle.com> ---

Boris, Here is the updated patch for determining number of regiter banks on AMD plus a patch removing shared_bank array, as you suggested. Offline/online testing didn''t show any issues. Boris Ostrovsky (2): x86/mce: Replace shared_bank array with is_shared_bank() helper x86/mce: Use MCG_CAP MSR to find out number of banks on AMD arch/x86/kernel/cpu/mcheck/mce_amd.c | 38

U-boot for the arndale board splits the memory in 8 contiguous banks and rewrites the memory node. So most of the memory is lost. As the frametable is only able to handle contiguous memory, use the first contiguous banks and warn if some of the memory banks are not used.

Large values are split into multiple blocks. References to these sub-blocks are kept in a list whose structure seems to be identical to a value list. A "db" record contains information on the number of sub-blocks and a pointer to the list. It is referenced by the vk record. I came across this when comparing the contents of HKLM\SOFTWARE hives from Windows7 systems and finding that

We disabled Nagle's algorithm to allow less latency in our responses reaching the client; but as a side effect, it leads to more network overhead when we send a reply split across more than one write(). Take advantage of various means for grouping related writes (Linux' MSG_MORE for sockets, gnutls' corking for TLS) to send a larger packet, and adjust callers to pass in our internal

It's useful to be able to search for the next non-zero entry in a bitmap. This commit adds a ?bitmap_next? function to do that. Because the bitmap is just a uint8_t buffer, using fast string functions we should be able to do this quickly even if the bitmap is sparse. (However the actual implementation is not optimized since that is quite complicated - see to-do comments in

Intercept guest reads of MSR_IA32_MCG_CAP and limit the number of memory banks reported to one. This prevents us from trying to read status of non-existent banks when migrated to a machine with fewer banks.

For GCC only, define unlikely() macro. Use it on error paths to move code out of the hot path. In the server only, use the debug() macro (don't call nbdkit_debug directly). This macro checks the verbose flag and moves the call to nbdkit_debug out of the hot path. --- server/connections.c | 11 ++++++----- server/internal.h | 17 ++++++++++++++++- server/plugins.c | 2 +-

Hi, This is updated xen vMCE design foils, according to comments from community recently. This foils focus on vMCE part of Xen MCA, so as Keir said, it''s some dense. Later Will will present a document to elaborate more, including Intel MCA and surrounding features and Xen implementation. Thanks, Jinsong

This issue I am encountering seems to only happen on multi-socket machines. It also does not help that the only multi-socket box I have is an Romley-EP (so two socket SandyBridge CPUs). The other SandyBridge boxes I''ve (one socket) are not showing this. Granted they are also a different model (42). The problem is that when I run ''perf top'' within an SMP PVHVM guest,

Hi! The MCG_CAP MSR never returns a negative count of available error-reporting banks. Thus make nr_mce_banks unsigned. While here, do some other minor cleanups.
