[PATCH v2 0/3] SM8450 IPA support
Posted by Esteban Urrutia 2 weeks, 2 days ago
This series has been tested on the following SoCs:
- SM7475
- SM8450
- SM8475
In these the modem works as expected and no crashes occur.

Signed-off-by: Esteban Urrutia <esteuwu@proton.me>

Changes in v2:
- Add missing resource limits for DMA and QDSS source groups.
  - These are marked as unused downstream, but still have values written
  to them.
- Add Nazar as a co-developer.
  - We developed independent implementations and are both working on
  this series.
- Add the IPA_MEM_MODEM_STATS_DROP memory region.
- Pick tags.
- Rebase against linux-next.
- Remove comment in driver stating smem_size differences.
  For both SM8450 and SM8475 SoCs:
  - All devices based on these SoCs use an smem_size of 0x9000. [1]
  - Specifying an smem_size of 0xb000 causes the modem to assert a
  shared memory allocation failure. [2]
- Remove overlapping optional memory regions.
  - No comments from anyone regarding these, so remove them.
- Reorder patches. (Dmitry, Krzysztof)
- Sort iommus property in DT. (Krzysztof)
- Specify actual IMEM base and size in DT. (Konrad)
- Update commit messages and cover letter.
- Link to v1: https://patch.msgid.link/20260622-sm8450-ipa-v1-0-532f0299f96e@proton.me

I forgot to mention that this series depends on the following patch:

Our CI isn't smart enough to pick up dependencies.
So you'll need to repost once that patch is present in net-next.
As is, patch 2/3 fails to build.

Also, I think the patch-set needs to be split up somehow
so the networking portions can be accepted into net-next
while the other patches go via a different subsystem.

For the net-next portion, please set the target tree in the subject
like this:

Subject: [PATCH v3 net-next] ...

For more information on the Netdev development process, please see:
