* x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'Kevin Winchester2012-08-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 141168c36cdee3ff23d9c7700b0edc47cb65479f and commit 3f806e50981825fa56a7f1938f24c0680816be45 upstream. Several fields in struct cpuinfo_x86 were not defined for the !SMP case, likely to save space. However, those fields still have some meaning for UP, and keeping them allows some #ifdef removal from other files. The additional size of the UP kernel from this change is not significant enough to worry about keeping up the distinction: text data bss dec hex filename 4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before 4737444 506459 972040 6215943 5ed907 vmlinux.o.after for a difference of 276 bytes for an example UP config. If someone wants those 276 bytes back badly then it should be implemented in a cleaner way.

* i7core_edac: return -ENODEV when devices were already probedMauro Carvalho Chehab2010-10-241-1/+1
| | | | | | | | | | | | Due to the nature of i7core, we need to probe and attach all PCI devices used by this driver during the first time probe is called. However, PCI core will call the probe routine one time for each CPU socket. If we return -EINVAL to those calls, it would seem that the driver fails, when, in fact, there's no more devices left to initialize. Changing the return code to -ENODEV solves this issue.

* i7core_edac: properly terminate pci_dev_tableMauro Carvalho Chehab2010-10-241-4/+5
| | | | | | | | | At pci_xeon_fixup(), it waits for a null-terminated table, while at i7core_get_all_devices, it just do a for 0..ARRAY_SIZE. As other tables are zero-terminated, change it to be terminate with 0 as well, and fixes a bug where it may be running out of the table elements.

* i7core_edac: Avoid PCI refcount to reach zero on successive load/reloadMauro Carvalho Chehab2010-10-241-0/+7
| | | | | | | | | | | | | | | | | | | | | That's a nasty bug that took me a lot of time to track, and whose solution took just one line to solve. The best fragrances and the worse poisons are shipped on the smalest bottles. The drivers/pci/quick.c implements the pci_get_device function. The normal behavior is that you call it, the function returns you a pdev pointer and increment pdev->kobj.kref.refcount of the pci device. However, if you want to keep searching an object, you need to pass the previous pdev function to the search. When you use a not null pointer to pdev "from" field, pci_get_device will decrement pdev->kobj.kref.refcount, assuming that the driver won't be using the previous pdev. The solution is simple: we just need to call pci_dev_get() manually, for the pdev's that the driver will actually use. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* i7core_edac: Fix refcount error at PCI devicesMauro Carvalho Chehab2010-10-241-35/+2
| | | | | | | | | | | | | Probably due to a bug or some testing logic at PCI level, device refcount for <bus>:00.0 device is decremented at the end of the pci_get_device, made by i7core_get_all_devices(). The fact is that the first versions of the driver relied on those devices to probe for Nehalem, but the current versions don't use it at all. So, let's just remove those devices from the driver, making it simpler and fixing the bug. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This is a nasty bug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a different register for one of the uncore PCI devices. 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>
