So the only possible case where this can happen is if CONFIG_INET is not enabled. This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS entry.

If GART gets an address that a device can't access to, GART try to map the address to a virtual I/O address that the device can access to. But Andi pointed out, "The GART is somewhere in the 4GB range so you cannot use it to map anything < 4GB. Also GART is pretty small." http://lkml.org/lkml/2008/9/12/43 That is, it's possible that GART doesn't have virtual I/O address space that a device can access to. The above behavior doesn't work for a device having dma_masks > 24bit < 32bits. This patch restores old GART alloc_coherent behavior (before the alloc_coherent rewrite).

If GART got an address that a device can't access to, GART mapped the address to a virtual I/O address. But GART mapping mechanism didn't take account of dma mask, so GART could use a virtual I/O address that the device can't access to again. Alan pointed out: " This is indeed a specific problem found with things like older AACRAID where control blocks must be below 31bits and the GART is above 0x80000000. " The above commit modified GART mapping mechanism to take care of dma mask. But Andi pointed out, "The GART is somewhere in the 4GB range so you cannot use it to map anything < 4GB. Also GART is pretty small." http://lkml.org/lkml/2008/9/12/43 That means it's possible that GART doesn't have virtual I/O address space that a device can access to. The above commit (to modify GART mapping mechanism to take care of dma mask) can't fix the regression reliably so let's avoid making GART more complicated. We need a solution that always works for dma_masks > 24bit < 32bits. That's how GART worked before the alloc_coherent rewrite.

| | | | * AMD IOMMU: use coherent_dma_mask in alloc_coherentJoerg Roedel2008-09-191-7/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alloc_coherent implementation for AMD IOMMU currently uses *dev->dma_mask per default. This patch changes it to prefer dev->coherent_dma_mask if it is set. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | * AMD IOMMU: use cmd_buf_size when freeing the command bufferJoerg Roedel2008-09-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command buffer release function uses the CMD_BUF_SIZE macro for get_order. Replace this with iommu->cmd_buf_size which is more reliable about the actual size of the buffer. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| | | | * AMD IOMMU: calculate IVHD size with a functionJoerg Roedel2008-09-191-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current calculation of the IVHD entry size is hard to read. So move this code to a seperate function to make it more clear what this calculation does. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| | | | * AMD IOMMU: remove unnecessary cast to u64 in the init codeJoerg Roedel2008-09-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ctrl variable is only u32 and readl also returns a 32 bit value. So the cast to u64 is pointless. Remove it with this patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| | | | * AMD IOMMU: free domain bitmap with its allocation orderJoerg Roedel2008-09-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The amd_iommu_pd_alloc_bitmap is allocated with a calculated order and freed with order 1. This is not a bug since the calculated order always evaluates to 1, but its unclean code. So replace the 1 with the calculation in the release path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86's common alloc_coherent (dma_alloc_coherent in dma-mapping.h) sets up the gfp flag according to the device dma_mask but AMD IOMMU doesn't need it for devices that the IOMMU can do virtual mappings for. This patch avoids unnecessary low zone allocation.

| | | | * AMD IOMMU: don't assign preallocated protection domains to devicesJoerg Roedel2008-09-192-5/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In isolation mode the protection domains for the devices are preallocated and preassigned. This is bad if a device should be passed to a virtualization guest because the IOMMU code does not know if it is in use by a driver. This patch changes the code to assign the device to the preallocated domain only if there are dma mapping requests for it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function determines if the AMD IOMMU implementation is responsible for a given device.
