[PATCH 09/28] iommu/amd: Move unmap_flush message to amd_iommu_init_dma_ops()

The message belongs there anyway, so move it to that function. Signed-off-by: Joerg Roedel joerg.roe...@amd.com --- drivers/iommu/amd_iommu.c |5 + drivers/iommu/amd_iommu_init.c |8 2 files changed, 5 insertions(+), 8 deletions(-) diff --git

[PATCH 12/28] iommu/amd: Keep track of HPET and IOAPIC device ids

The IVRS ACPI table provides information about the IOAPICs and the HPETs available in the system and which PCI device ID they use in transactions. Save that information for later usage in interrupt remapping. Signed-off-by: Joerg Roedel joerg.roe...@amd.com --- drivers/iommu/amd_iommu.c |

[PATCH 01/28] x86/irq: Add data structure to keep AMD specific irq remapping information

Add a data structure to store information the IOMMU driver can use to get from a 'struct irq_cfg' to the remapping entry. Cc: x...@kernel.org Cc: Yinghai Lu ying...@kernel.org Cc: Suresh Siddha suresh.b.sid...@intel.com Signed-off-by: Joerg Roedel joerg.roe...@amd.com ---

[PATCH 13/28] iommu/amd: Add slab-cache for irq remapping tables

The irq remapping tables for the AMD IOMMU need to be aligned on a 128 byte boundary. Create a seperate slab-cache to guarantee this alignment. Signed-off-by: Joerg Roedel joerg.roe...@amd.com --- drivers/iommu/amd_iommu.c |2 ++ drivers/iommu/amd_iommu_init.c | 23

[PATCH 05/28] iommu/amd: Split out PCI related parts of IOMMU initialization

For interrupt remapping the relevant IOMMU initialization needs to run earlier at boot when the PCI subsystem is not yet initialized. To support that this patch splits the parts of IOMMU initialization which need PCI accesses out of the initial setup path so that this can be done later.

[PATCH 11/28] iommu/amd: Convert iommu initialization to state machine

This step makes it very easy to keep track about the current intialization state of the iommu driver. With this change we can initialize the IOMMU hardware to a point where it can remap interrupts and later resume the initializion to enable dma remapping. Signed-off-by: Joerg Roedel

[PATCH 27/28] iommu/amd: Print message to system log when irq remapping is enabled

Print an indicator to dmesg to easily find out if interrupt remapping is enabled of a given system. Signed-off-by: Joerg Roedel joerg.roe...@amd.com --- drivers/iommu/amd_iommu_init.c |2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/iommu/amd_iommu_init.c

[PATCH 04/28] iommu/amd: Use acpi_get_table instead of acpi_table_parse

This makes it easier to propagate errors while parsing the IVRS table and makes the amd_iommu_init_err hack obsolete. Signed-off-by: Joerg Roedel joerg.roe...@amd.com --- drivers/iommu/amd_iommu_init.c | 118 ++-- 1 file changed, 66 insertions(+), 52

[PATCH 17/28] iommu/amd: Split device table initialization into irq and dma part

When the IOMMU is enabled very early (as with irq-remapping) some devices are still in BIOS hand. When dma is blocked early this can cause lots of IO_PAGE_FAULTs. So delay the DMA initialization and do it right before the dma_ops are initialized. Signed-off-by: Joerg Roedel joerg.roe...@amd.com

[PATCH 19/28] iommu/amd: Add IRTE invalidation routine

[PATCH 15/28] iommu/amd: Check if IOAPIC information is correct

When the IOAPIC information provided in the IVRS table is not correct or not complete the system may not boot at all when interrupt remapping is enabled. So check if this information is correct and print out a firmware bug message when it is not. Signed-off-by: Joerg Roedel joerg.roe...@amd.com
