| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support more than just the "Misc Control" part of the northbridges. Support more flags by turning "gart_supported" into a single bit flag that is stored in a flags member. Clean up related code by using a set of functions (amd_nb_num(), amd_nb_has_feature() and node_to_amd_nb()) instead of accessing the NB data structures directly. Reorder the initialization code and put the GART flush words caching in a separate function.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | Not only the naming of the files was confusing, it was even more so for the function and variable names. Renamed the K8 NB and NUMA stuff that is also used on other AMD platforms. This also renames the CONFIG_K8_NUMA option to CONFIG_AMD_NUMA and the related file k8topology_64.c to amdtopology_64.c.

* | amd64_edac: Fix interleaving checkBorislav Petkov2010-12-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When matching error address to the range contained by one memory node, we're in valid range when node interleaving 1. is disabled, or 2. enabled and when the address bits we interleave on match the interleave selector on this node (see the "Node Interleaving" section in the BKDG for an enlightening example). Thus, when we early-exit, we need to reverse the compound logic statement properly. Cc: <stable@kernel.org> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

* | EDAC: Fix workqueue-related crashesBorislav Petkov2010-12-081-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 00740c58541b6087d78418cebca1fcb86dc6077d changed edac_core to un-/register a workqueue item only if a lowlevel driver supplies a polling routine. Normally, when we remove a polling low-level driver, we go and cancel all the queued work. However, the workqueue unreg happens based on the ->op_state setting, and edac_mc_del_mc() sets this to OP_OFFLINE _before_ we cancel the work item, leading to NULL ptr oops on the workqueue list. Fix it by putting the unreg stuff in proper order.

| * 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>

| * i7core_edac: Properly mark const static vars as suchMauro Carvalho Chehab2010-10-243-46/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two groups of sysfs attributes: one for rdimm and another for udimm. Instead of changing dynamically the unique static struct for handling udimm's, declare two vars and make them constant. This avoids the risk of having two or more memory controllers, each needing a different set of attributes. While here, use const on all places where it is applicable.
