[PATCH 00/13] s390x/pci: s390-pci updates for kernel 5.10-rc1
Posted by Matthew Rosato 5 years ago 
Combined set of patches that exploit vfio/s390-pci features available in
kernel 5.10-rc1.  This patch set is a combination of 

[PATCH v4 0/5] s390x/pci: Accomodate vfio DMA limiting

and

[PATCH v3 00/10] Retrieve zPCI hardware information from VFIO

with duplicate patches removed and a single header sync.  All patches have
prior maintainer reviews except for:

- Patch 1 (update-linux-headers change to add new file) 
- Patch 2 (header sync against 5.10-rc1)
- Patch 13 - contains a functional (debug) change; I switched from using
  DPRINTFs to using trace events per Connie's request.



Matthew Rosato (10):
  update-linux-headers: Add vfio_zdev.h
  linux-headers: update against 5.10-rc1
  s390x/pci: Move header files to include/hw/s390x
  vfio: Create shared routine for scanning info capabilities
  vfio: Find DMA available capability
  s390x/pci: Add routine to get the vfio dma available count
  s390x/pci: Honor DMA limits set by vfio
  s390x/pci: clean up s390 PCI groups
  vfio: Add routine for finding VFIO_DEVICE_GET_INFO capabilities
  s390x/pci: get zPCI function info from host

Pierre Morel (3):
  s390x/pci: create a header dedicated to PCI CLP
  s390x/pci: use a PCI Group structure
  s390x/pci: use a PCI Function structure

That one has ;)

I'm still unsure about the rdma/(q)atomic stuff -- had we reached any
conclusion there?

Ugh, I forgot about this...  I had CC'd the associated maintainers a few 
times but never heard back from anyone on how to resolve this.

Paolo said previously this stuff should not have been imported by a 
header sync in the first place 
(https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg00734.html), 
so I would guess that the proper fix is to stop importing the rdma stuff 
and (re)define it somewhere in QEMU.

We could just drop the rmda file hit from this sync, but it's going to 
keep happening until the code is removed from the kernel header.

I think so.

Yeah.

It's unfortunate that 5.10-rc1 and the soft freeze are so close
together :(
