Subject: [PATCH v6 00/33] MT8192 IOMMU support
Date: Mon, 11 Jan 2021 19:18:41 +0800 [thread overview]
Message-ID: <20210111111914.22211-1-yong.wu@mediatek.com> (raw)
This patch mainly adds support for mt8192 Multimedia IOMMU and SMI.
mt8192 also is MTK IOMMU gen2 which uses ARM Short-Descriptor translation
table format. The M4U-SMI HW diagram is as below:
EMI
|
M4U
|
------------
SMI Common
------------
|
+-------+------+------+----------------------+-------+
| | | | ...... | |
| | | | | |
larb0 larb1 larb2 larb4 ...... larb19 larb20
disp0 disp1 mdp vdec IPE IPE
All the connections are HW fixed, SW can NOT adjust it.
Comparing with the preview SoC, this patchset mainly adds two new functions:
a) add iova 34 bits support.
b) add multi domains support since several HW has the special iova
region requirement.
change note:
v6:a) base on v5.11-rc1. and tlb v4:
https://lore.kernel.org/linux-mediatek/20210107122909.16317-1-yong.wu@mediatek.com/T/#t
b) Remove the "domain id" definition in the binding header file.
Get the domain from dev->dma_range_map.
After this, Change many codes flow.
c) the patchset adds a new common file(mtk_smi-larb-port.h).
This version changes that name into mtk-memory-port.h which reflect
its file path. This only changes the file name. no other change.
thus I keep all the Reviewed-by Tags.
(another reason is that we will add some iommu ports unrelated with
smi-larb)
d) Refactor the power-domain flow suggestted by Tomasz.
e) Some other small fix. use different oas for different soc; Change the
macro for 34bit iova tlb flush.
v5: https://lore.kernel.org/linux-iommu/20201209080102.26626-1-yong.wu@mediatek.com/
a) Add a new patch for the header guard for smi-larb-port.h in [5/27].
b) Add a new patch for error handle for iommu_device_sysfs_add and
iommu_device_register[15/27].
c) Add a flag for the iova "ias == 34" case. the previous SoC still keep
32bits to save 16KB*3 lvl1 pgtable memory[13/27].
d) Add include <linux/bitfield.h> for FIELD_GET build fail.
e) In PM power domain patch, add a checking "pm_runtime_enabled" when call
pm_runtime_get_sync for non power-domain case. and add a pm_runtime_put_noidle
while pm_runtime_get_sync fail case.
v4: https://lore.kernel.org/linux-iommu/20201111123838.15682-1-yong.wu@mediatek.com/
a) rebase on v5.10-rc1
b) Move the smi part to a independent patchset.
c) Improve v7s code from Robin and Will.
d) Add a mediatek iommu entry patch in MAINTAIN.
v3: https://lore.kernel.org/linux-iommu/20200930070647.10188-1-yong.wu@mediatek.com/
a) Fix DT schema issue commented from Rob.
b) Fix a v7s issue. Use "_lvl" instead of "_l" in the macro(ARM_V7S_PTES_PER_LVL) since
it is called in ARM_V7S_LVL_IDX which has already used "_l".
c) Fix a PM suspend issue: Avoid pm suspend in pm runtime case.
v2: https://lore.kernel.org/linux-iommu/20200905080920.13396-1-yong.wu@mediatek.com/
a) Convert IOMMU/SMI dt-binding to DT schema.
b) Fix some comment from Pi-Hsun and Nicolas. like use
generic_iommu_put_resv_regions.
c) Reword some comment, like add how to use domain-id.

Subject: [PATCH v6 00/33] MT8192 IOMMU support
Date: Mon, 11 Jan 2021 19:18:41 +0800 [thread overview]
Message-ID: <20210111111914.22211-1-yong.wu@mediatek.com> (raw)
This patch mainly adds support for mt8192 Multimedia IOMMU and SMI.
mt8192 also is MTK IOMMU gen2 which uses ARM Short-Descriptor translation
table format. The M4U-SMI HW diagram is as below:
EMI
|
M4U
|
------------
SMI Common
------------
|
+-------+------+------+----------------------+-------+
| | | | ...... | |
| | | | | |
larb0 larb1 larb2 larb4 ...... larb19 larb20
disp0 disp1 mdp vdec IPE IPE
All the connections are HW fixed, SW can NOT adjust it.
Comparing with the preview SoC, this patchset mainly adds two new functions:
a) add iova 34 bits support.
b) add multi domains support since several HW has the special iova
region requirement.
change note:
v6:a) base on v5.11-rc1. and tlb v4:
https://lore.kernel.org/linux-mediatek/20210107122909.16317-1-yong.wu@mediatek.com/T/#t
b) Remove the "domain id" definition in the binding header file.
Get the domain from dev->dma_range_map.
After this, Change many codes flow.
c) the patchset adds a new common file(mtk_smi-larb-port.h).
This version changes that name into mtk-memory-port.h which reflect
its file path. This only changes the file name. no other change.
thus I keep all the Reviewed-by Tags.
(another reason is that we will add some iommu ports unrelated with
smi-larb)
d) Refactor the power-domain flow suggestted by Tomasz.
e) Some other small fix. use different oas for different soc; Change the
macro for 34bit iova tlb flush.
v5: https://lore.kernel.org/linux-iommu/20201209080102.26626-1-yong.wu@mediatek.com/
a) Add a new patch for the header guard for smi-larb-port.h in [5/27].
b) Add a new patch for error handle for iommu_device_sysfs_add and
iommu_device_register[15/27].
c) Add a flag for the iova "ias == 34" case. the previous SoC still keep
32bits to save 16KB*3 lvl1 pgtable memory[13/27].
d) Add include <linux/bitfield.h> for FIELD_GET build fail.
e) In PM power domain patch, add a checking "pm_runtime_enabled" when call
pm_runtime_get_sync for non power-domain case. and add a pm_runtime_put_noidle
while pm_runtime_get_sync fail case.
v4: https://lore.kernel.org/linux-iommu/20201111123838.15682-1-yong.wu@mediatek.com/
a) rebase on v5.10-rc1
b) Move the smi part to a independent patchset.
c) Improve v7s code from Robin and Will.
d) Add a mediatek iommu entry patch in MAINTAIN.
v3: https://lore.kernel.org/linux-iommu/20200930070647.10188-1-yong.wu@mediatek.com/
a) Fix DT schema issue commented from Rob.
b) Fix a v7s issue. Use "_lvl" instead of "_l" in the macro(ARM_V7S_PTES_PER_LVL) since
it is called in ARM_V7S_LVL_IDX which has already used "_l".
c) Fix a PM suspend issue: Avoid pm suspend in pm runtime case.
v2: https://lore.kernel.org/linux-iommu/20200905080920.13396-1-yong.wu@mediatek.com/
a) Convert IOMMU/SMI dt-binding to DT schema.
b) Fix some comment from Pi-Hsun and Nicolas. like use
generic_iommu_put_resv_regions.
c) Reword some comment, like add how to use domain-id.
v1: https://lore.kernel.org/linux-iommu/20200711064846.16007-1-yong.wu@mediatek.com/
