MT8188 have 3 IOMMU HWs. 2 IOMMU HW is for multimedia, and 1 IOMMU HW
is for infra-master, like PCIe.
About the 2 MM IOMMU HW, the connection could be something like this:
IOMMU(VDO) IOMMU(VPP)
| |
SMI_COMMON(VDO) SMI_COMMON(VPP)
--------------- ----------------
| | ... | | ...
larb0 larb2 ... larb1 larb3 ...
INFRA IOMMU does not have SMI, the master connects to IOMMU directly.
Although multiple banks supported in MT8188, we only use one of them,
which means PCIe is put in bank0 of INFRA IOMMU.
So we have two pgtable for MT8188, specifically, these two MM IOMMU HW
share a pgtable while INFRA IOMMU HW use a independent pgtable.
Another change is that we add some SMC command for INFRA master to
enable/disable INFRA IOMMU in ATF considering security concerns.
We also adjust the flow of mtk_iommu_config to reduce indention.
change in v11:
- Just add a new entry in MAINTAINERS from AngeloGioacchino.
change in v10:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Add a Fixes tag for [2/7].
- Rebase on mtk-iommu-dma-range-v7:
https://lore.kernel.org/linux-mediatek/[email protected]/
change since v9:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Move the patch about setting set_dma_mask out from this patchset.
- Add a MAINTAINER patch since the header file was added a prefix "mediatek,"
change since v8:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Base on v6.3-rc1 and mtk-iommu-dma-range-v5:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Add a new patch set_dma_mask about since mt8188 support the PA of pgtable 35bits.
changes since v7:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Base on mtk-iommu-dma-range-v4:
https://lore.kernel.org/linux-mediatek/[email protected]/
- Add a new patch for two IOMMU share pagetable issue.
- Add a new patch for adding iova_region_larb_msk for mt8188.
- Add the comment in the dt-binding header file about larb index.
This is for readable when updating the iova_region_larb_msk.
Since there is something wrong for chengci's mail account when sending
to devicetree mail list, we don't know why. I help send this patchset.

2.18.0
From: "Chengci.Xu" <[email protected]>
Add descriptions for mt8188 IOMMU which also use ARM Short-Descriptor
translation table format.
In mt8188, there are two smi-common HW and IOMMU, one is for vdo(video
output), the other is for vpp(video processing pipe). They connects
with different smi-larbs, then some setting(larbid_remap) is different.
Differentiate them with the compatible string.
Something like this:
IOMMU(VDO) IOMMU(VPP)
| |
SMI_COMMON_VDO SMI_COMMON_VPP
--------------- ----------------
| | ... | | ...
larb0 larb2 ... larb1 larb3 ...
We also have an IOMMU that is for infra master like PCIe.
And infra master don't have the larb and ports.

2.25.1
From: "Chengci.Xu" <[email protected]>
Prepare for mt8188 to fix a two IOMMU HWs share pagetable issue.
We have two MM IOMMU HWs in mt8188, one is VPP-IOMMU, the other is
VDO-IOMMU. The 2 MM IOMMU HWs share pagetable don't work in this case:
a) VPP-IOMMU probe firstly.
b) VDO-IOMMU probe.
c) The master for VDO-IOMMU probe (means frstdata is vpp-iommu).
d) The master in another domain probe. No matter it is vdo or vpp.
Then it still create a new pagetable in step d). The problem is
"frstdata->bank[0]->m4u_dom" was not initialized. Then when d) enter, it
still create a new one.
In this patch, we create a new variable "share_dom" for this share
pgtable case, it should be helpful for readable. and put all the share
pgtable logic in the mtk_iommu_domain_finalise.
In mt8195, the master of VPP-IOMMU probes before than VDO-IOMMU
from its dtsi node sequence, we don't see this issue in it. Prepare for
mt8188.

From: "Chengci.Xu" <[email protected]>
If there are many ports in a infra master, current flow will update
the INFRA register many times. This patch saves all ports to portid_msk
in the front of mtk_iommu_config(), then update only once for the IOMMU
configure. After this, we could avoid send too many SMC calls to ATF in
MT8188.
Prepare for MT8188, also reduce the indention without functional change.

Prepare for MT8188. In MT8188, the register which enables IOMMU for
INFRA masters are in the secure world for security concerns, therefore we
add a SMC command for INFRA masters to enable IOMMU in ATF.

2.25.1
Add iova_region_larb_msk for mt8188. We separate the 16GB iova regions
by each device's larbid/portid.
Refer to include/dt-bindings/memory/mediatek,mt8188-memory-port.h
As commented in the code, larb19(21) means it's larb19 while its SW index
is 21.

We add the prefix "mediatek," for the lastest ports header file name,
For example, include/dt-bindings/memory/mediatek,mt8188-memory-port.h.
Add a new entry for this.
