edac, highbank: Fix interrupt setup of mem and l2 controller

2013-12-04T19:05:53+00:00

commit a72b8859fd3941cc1d2940d5c43026d2c6fb959e upstream.

Register and enable interrupts after the edac registration. Otherwise
incomming ecc error interrupts lead to crashes during device setup.

Fixing this in drivers for mc and l2.

Pull Tile arch updates from Chris Metcalf:
 "These changes bring in a bunch of new functionality that has been
  maintained internally at Tilera over the last year, plus other stray
  bits of work that I've taken into the tile tree from other folks.

  The changes include some PCI root complex work, interrupt-driven
  console support, support for performing fast-path unaligned data
  fixups by kernel-based JIT code generation, CONFIG_PREEMPT support,
  vDSO support for gettimeofday(), a serial driver for the tilegx
  on-chip UART, KGDB support, more optimized string routines, support
  for ftrace and kprobes, improved ASLR, and many bug fixes.

  We also remove support for the old TILE64 chip, which is no longer
  buildable"

amd64_edac: Fix incorrect wraparounds

2013-08-27T13:00:22+00:00

dct_base and dct_limit obtain 32 bit register values when they read
their respective pci config space registers. A left shift beyond 32 bits
will cause them to wrap around. Similar case for chan_addr as can be
seen from the bug report (link below). In the patch, we rectify this by
casting chan_addr to u64 and by comparing dct_base and dct_limit against
properly shifted sys_addr in order to compare the correct bits.

amd64_edac: Get rid of boot_cpu_data accesses

2013-08-12T14:01:56+00:00

Now that we cache (family, model, stepping) locally, use them instead of
boot_cpu_data.

amd64_edac: Add ECC decoding support for newer F15h models

2013-08-12T14:00:10+00:00

On newer models, support has been included for upto 4 DCT's, however,
only DCT0 and DCT3 are currently configured (cf BKDG Section 2.10).
Also, the routing DRAM Requests algorithm is different for F15h M30h.
Thus it is cleaner to use a brand new function rather than adding quirks
to the more generic f1x_match_to_this_node(). Refer to "2.10.5 DRAM
Routing Requests" in the BKDG for further info.

Tested on Fam15h M30h with ECC turned on using mce_amd_inj facility and
verified to be functionally correct.

While at it, verify if erratum workarounds for E505 and E637 still hold.
From email conversations within AMD, the current status of the errata
is:

      * Erratum 505: fixed in model 0x1, stepping 0x1 and later.
      * Erratum 637: not fixed.
