Add support for it. Those are the PCI ID's on this new chipset: fe:00.0 0600: 8086:2c70 (rev 02) fe:00.1 0600: 8086:2d81 (rev 02) fe:02.0 0600: 8086:2d90 (rev 02) fe:02.1 0600: 8086:2d91 (rev 02) fe:02.2 0600: 8086:2d92 (rev 02) fe:02.3 0600: 8086:2d93 (rev 02) fe:02.4 0600: 8086:2d94 (rev 02) fe:02.5 0600: 8086:2d95 (rev 02) fe:03.0 0600: 8086:2d98 (rev 02) fe:03.1 0600: 8086:2d99 (rev 02) fe:03.2 0600: 8086:2d9a (rev 02) fe:03.4 0600: 8086:2d9c (rev 02) fe:04.0 0600: 8086:2da0 (rev 02) fe:04.1 0600: 8086:2da1 (rev 02) fe:04.2 0600: 8086:2da2 (rev 02) fe:04.3 0600: 8086:2da3 (rev 02) fe:05.0 0600: 8086:2da8 (rev 02) fe:05.1 0600: 8086:2da9 (rev 02) fe:05.2 0600: 8086:2daa (rev 02) fe:05.3 0600: 8086:2dab (rev 02) fe:06.0 0600: 8086:2db0 (rev 02) fe:06.1 0600: 8086:2db1 (rev 02) fe:06.2 0600: 8086:2db2 (rev 02) fe:06.3 0600: 8086:2db3 (rev 02) (as usual, the same PCI devices repeat at ff: bus) The PCI device 8086:2c70 is shown as: fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic Non-core Registers (rev 02) So, for this device to be recognized, it is only a matter of adding this new PCI ID to the driver.

| * Always call i7core_[ur]dimm_check_mc_ecc_errVernon Mauery2010-05-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an error in function i7core_check_error In commit ca9c90ba09ca3c9799319f46a56f397afbf617c2 which converts the driver to use double buffering, there is a change in the logic. Before, if mce_count was zero, it skipped over a couple of statements and finished out with a call to the *check_mc_ecc_err function. The current code checks to see if mce_count is 0 and then exits. This change reverts the behavior back to the original where if there are no errors to report, we skip to the end and call the *check_mc_ecc_err function. This fix allows the driver to work again on my Nehalem based blades again. Signed-off-by: Vernon Mauery <vernux@us.ibm.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The old remove module stragegy didn't work on devices with multiple cores, since only one PCI device is used to open all mc's, due to Nehalem nature. Also, it were based at pdev value. However, this doesn't point to the pci device used at mci->dev. So, instead, it unregisters all devices at once, deleting them from the device list.

| * Dynamically allocate memory for PCI devicesMauro Carvalho Chehab2010-05-101-61/+114
| | | | | | | | | | | | | | | | | | Instead of using a static table assuming always 2 CPU sockets, allocate space dynamically for Nehalem PCI devs. This patch is part of a series of patches that changes i7core_edac to allow more than 2 sockets and to properly report one memory controller per socket.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On the Xeon 55XX series cpus the pci deives are not exposed via acpi so we much explicitly probe them to make the usable as a Linux PCI device. This moves the detection of this state to before pci_register_driver is called. Its present position was not working on my systems, the driver would complain about not finding a specific device.

| | | | | | | | | | | | | | | | | | | | | | | | Instead of assuming that the entire machine has either registered or unregistered memories, do it at CPU socket based. While here, fix a bug at i7core_mce_output_error(), where the we're using m->cpu directly as if it would represent a socket. Instead, the proper socket_id is given by cpu_data[m->cpu].phys_proc_id.

| * i7core_edac: Use Device 3 function 2 to report errors with RDIMM'sMauro Carvalho Chehab2010-05-101-30/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nehalem and upper chipsets provide an special device that has corrected memory error counters detected with registered dimms. This device is only seen if there are registered memories plugged. After this patch, on a machine fully equiped with RDIMM's, it will use the Device 3 function 2 to count corrected errors instead on relying at mcelog. For unregistered DIMMs, it will keep the old behavior, counting errors via mcelog.
