* x86: amd_iommu: move to drivers/iommu/Ohad Ben-Cohen2011-06-211-2764/+0
| | | | | | | | | | | This should ease finding similarities with different platforms, with the intention of solving problems once in a generic framework which everyone can use. Compile-tested on x86_64. Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
* x86/amd-iommu: Fix boot crash with hidden PCI devicesJoerg Roedel2011-06-071-1/+21
| | | | | | | | | | | | | | Some PCIe cards ship with a PCI-PCIe bridge which is not visible as a PCI device in Linux. But the device-id of the bridge is present in the IOMMU tables which causes a boot crash in the IOMMU driver. This patch fixes by removing these cards from the IOMMU handling. This is a pure -stable fix, a real fix to handle this situation appriatly will follow for the next merge window. Cc: stable@kernel.org # > 2.6.32 Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
* x86/amd-iommu: Use only per-device dma_opsJoerg Roedel2011-06-061-2/+24
| | | | | | | | | | | Unfortunatly there are systems where the AMD IOMMU does not cover all devices. This breaks with the current driver as it initializes the global dma_ops variable. This patch limits the AMD IOMMU to the devices listed in the IVRS table fixing DMA for devices not covered by the IOMMU. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

| * x86/amd-iommu: Flush all internal TLBs when IOMMUs are enabledJoerg Roedel2011-04-071-41/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | The old code only flushed a DTE or a domain TLB before it is actually used by the IOMMU driver. While this is efficient and works when done right it is more likely to introduce new bugs when changing code (which happened in the past). This patch adds code to flush all DTEs and all domain TLBs in each IOMMU right after it is enabled (at boot and after resume). This reduces the complexity of the driver and makes it less likely to introduce stale-TLB bugs in the future. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

| | | | | | | | | | | | | | | | | | | | The logic to reset the command buffer caused more problems than it actually helped. The logic jumped in when the IOMMU hardware doesn't execute commands anymore but the reasons for this are usually not fixed by just resetting the command buffer.

* x86/amd-iommu: Fix rounding-bug in __unmap_singleJoerg Roedel2010-09-231-1/+3
| | | | | | | | | | | | | In the __unmap_single function the dma_addr is rounded down to a page boundary before the dma pages are unmapped. The address is later also used to flush the TLB entries for that mapping. But without the offset into the dma page the amount of pages to flush might be miscalculated in the TLB flushing path. This patch fixes this bug by using the original address to flush the TLB. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

This can leave the device using stale cached IOMMU data, and result in a non-functional device after it's re-bound to the host driver. For example, I see this upon rebinding: AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8000 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8040 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a8080 flags=0x0050] AMD-Vi: Event logged [IO_PAGE_FAULT device=02:00.0 domain=0x0000 address=0x000000007e2a80c0 flags=0x0050] 0000:02:00.0: eth2: Detected Hardware Unit Hang: ...

* / include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
