The only change to the IOMMU core code is the addition of a handle to the fault handling code. A few updates to the AMD IOMMU driver to work around new errata. The other patches are mostly fixes and enhancements to the existing ARM IOMMU drivers and documentation updates. A new IOMMU driver for the Exynos platform was also underway but got merged via the Samsung tree and is not part of this tree." * tag 'iommu-updates-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: Documentation: kernel-parameters.txt Add amd_iommu_dump iommu/core: pass a user-provided token to fault handlers iommu/tegra: gart: Fix register offset correctly iommu: OMAP: device detach on domain destroy iommu: tegra/gart: Add device tree support iommu: tegra/gart: use correct gart_device iommu/tegra: smmu: Print device name correctly iommu/amd: Add workaround for event log erratum iommu/amd: Check for the right TLP prefix bit dma-debug: release free_entries_lock before saving stack trace

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes a single IOMMU user may have to deal with several different IOMMU devices (e.g. remoteproc). When an IOMMU fault happens, such users have to regain their context in order to deal with the fault. Users can't use the private fields of neither the iommu_domain nor the IOMMU device, because those are already used by the IOMMU core and low level driver (respectively). This patch just simply allows users to pass a private token (most notably their own context pointer) to iommu_set_fault_handler(), and then makes sure it is provided back to the users whenever an IOMMU fault happens. The patch also adopts remoteproc to the new fault handling interface, but the real functionality using this (recovery of remote processors) will only be added later in a subsequent patch set.

If the domain is destroyed the hardware still has access to invalid pointers to its page table and internal iommu object. In order to detach the users we need to track devices using the iommu, current use cases only have one user of iommu per instance. When required this can evolve to a list with the devices using the iommu_dev.

On this set, it changes the Kernel EDAC API in order to properly represent the Intel i3/i5/i7, Xeon 3xxx/5xxx/7xxx, and Intel E5-xxxx memory controllers. The EDAC core used to assume that: - the DRAM chip select pin is directly accessed by the memory controller - when multiple channels are used, they're all filled with the same type of memory. None of the above premises is true on Intel memory controllers since 2002, when RAMBUS and FB-DIMMs were introduced, and Advanced Memory Buffer or by some similar technologies hides the direct access to the DRAM pins. So, the existing drivers for those chipsets had to lie to the EDAC core, in general telling that just one channel is filled. That produces some hard to understand error messages like: EDAC MC0: CE row 3, channel 0, label "DIMM1": 1 Unknown error(s): memory read error on FATAL area : cpu=0 Err=0008:00c2 (ch=2), addr = 0xad1f73480 => socket=0, Channel=0(mask=2), rank=1 The location information there (row3 channel 0) is completely bogus: it has no physical meaning, and are just some random values that the driver uses to talk with the EDAC core. The error actually happened at CPU socket 0, channel 0, slot 1, but this is not reported anywhere, as the EDAC core doesn't know anything about the memory layout. So, only advanced users that know how the EDAC driver works and that tests their systems to see how DIMMs are mapped can actually benefit for such error logs. This patch series fixes the error report logic, in order to allow the EDAC to expose the memory architecture used by them to the EDAC core. So, as the EDAC core now understands how the memory is organized, it can provide an useful report: EDAC MC0: CE memory read error on DIMM1 (channel:0 slot:1 page:0x364b1b offset:0x600 grain:32 syndrome:0x0 - count:1 area:DRAM err_code:0001:0090 socket:0 channel_mask:1 rank:4) The location of the DIMM where the error happened is reported by "MC0" (cpu socket #0), at "channel:0 slot:1" location, and matches the physical location of the DIMM. There are two remaining issues not covered by this patch series: - The EDAC sysfs API will still report bogus values. So, userspace tools like edac-utils will still use the bogus data; - Add a new tracepoint-based way to get the binary information about the errors. Those are on a second series of patches (also at -next), but will probably miss the train for 3.5, due to the slow review process."

Only one of the csrows will contain the entire DIMM size. If single rank memories are found, they'll be marked with 0 bytes. The check if the AMB is present were also wrong. Yet, as the error reports don't use the memory size in order to credit an error to the right DIMM, that part of the driver seems to work. That's why probably nobody detected the issue yet. After this patch, the memory layout is now properly reported, when debug mode is enabled, and the number of ranks per dimm is now shown: calculate_dimm_size: ---------------------------------------------------------- calculate_dimm_size: slot 3 0 MB | 0 MB | 0 MB | 0 MB | calculate_dimm_size: slot 2 0 MB | 0 MB | 0 MB | 0 MB | calculate_dimm_size: ---------------------------------------------------------- calculate_dimm_size: slot 1 0 MB | 0 MB | 0 MB | 0 MB | calculate_dimm_size: slot 0 512 MB 1R| 512 MB 1R| 512 MB 1R| 512 MB 1R| calculate_dimm_size: ---------------------------------------------------------- calculate_dimm_size: channel 0 | channel 1 | channel 2 | channel 3 | calculate_dimm_size: branch 0 | branch 1 | (1R above means that all memories on my test machine are single-ranked) Reviewed-by: Aristeu Rozanski <arozansk@redhat.com> Cc: Doug Thompson <norsk5@yahoo.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * | | | edac: Initialize the dimm label with the known informationMauro Carvalho Chehab2012-05-292-10/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While userspace doesn't fill the dimm labels, add there the dimm location, as described by the used memory model. This could eventually match what is described at the dmidecode, making easier for people to identify the memory. For example, on an Intel motherboard where the DMI table is reliable, the first memory stick is described as: Memory Device Array Handle: 0x0029 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 2048 MB Form Factor: DIMM Set: 1 Locator: A1_DIMM0 Bank Locator: A1_Node0_Channel0_Dimm0 Type: <OUT OF SPEC> Type Detail: Synchronous Speed: 800 MHz Manufacturer: A1_Manufacturer0 Serial Number: A1_SerNum0 Asset Tag: A1_AssetTagNum0 Part Number: A1_PartNum0 The memory named as "A1_DIMM0" is physically located at the first memory controller (node 0), at channel 0, dimm slot 0. After this patch, the memory label will be filled with: /sys/devices/system/edac/mc/csrow0/ch0_dimm_label:mc#0channel#0slot#0 And (after the new EDAC API patches) as: /sys/devices/system/edac/mc/mc0/dimm0/dimm_label:mc#0channel#0slot#0 So, even if the memory label is not initialized on userspace, an useful information with the error location is filled there, expecially since several systems/motherboards are provided with enough info to map from channel/slot (or branch/channel/slot) into the DIMM label. So, letting the EDAC core fill it by default is a good thing. It should noticed that, as the label filling happens at the edac_mc_alloc(), drivers can override it to better describe the memories (and some actually do it).
