[PATCH 0/5] bridges without VGA support

[PATCH 0/5] bridges without VGA support

[Simon Richter]

Hi,

this allows bridges to refuse forwarding VGA, and reports this upwards as an
error, because we cannot set up valid decoding for the requested device in this
case.

I think it should be fine to leave VGA forwarding enabled on lower bridges if a
bridge closer to the root refused to enable forwarding, because no accesses can
reach there anyway.

[PATCH 1/5] vgaarb: pass vga_get errors to userspace

[Simon Richter]

If vga_get fails, return the error code via the write syscall.

[PATCH 2/5] vgaarb: pass errors from pci_set_vga_state up

[Simon Richter]

pci_set_vga_state returns an error code, which so far has been ignored. Pass
this code through __vga_tryget (via ERR_PTR).

[PATCH 3/5] vgaarb: mark vga_get family as __must_check

[Simon Richter]

These functions can return an error, but some callers expect they don't, and
unconditionally access VGA registers afterwards and call vga_put.

[PATCH 4/5] pci: check if VGA decoding was really activated

[Simon Richter]

PCI bridges are allowed to refuse activating VGA decoding, by simply ignoring
attempts to set the bit that enables it, so after setting the bit, read it
back to verify.

One example of such a bridge is the root bridge in IBM PowerNV.

[PATCH v2 0/5] Bridges without VGA support

[Simon Richter]

Hi,

v2 fixes the formatting errors.

This allows bridges to refuse forwarding VGA, and reports this upwards as an
error, because we cannot set up valid decoding for the requested device in this
case.

I think it should be fine to leave VGA forwarding enabled on lower bridges if a
bridge closer to the root refused to enable forwarding, because no accesses can
reach there anyway.

   Simon

[PATCH v2 2/5] vgaarb: pass errors from pci_set_vga_state up

[Simon Richter]

pci_set_vga_state returns an error code, which so far has been ignored.
Pass this code through __vga_tryget (via ERR_PTR).

[PATCH v2 3/5] vgaarb: mark vga_get family as __must_check

[Simon Richter]

These functions can return an error, but some callers expect they don't,
and unconditionally access VGA registers afterwards and call vga_put.

[PATCH v2 4/5] pci: check if VGA decoding was really activated

[Simon Richter]

PCI bridges are allowed to refuse activating VGA decoding, by simply
ignoring attempts to set the bit that enables it, so after setting the bit,
read it back to verify.

One example of such a bridge is the root bridge in IBM PowerNV.

I'm not sure if you also fixed the kernel test robot warnings
(https://lore.kernel.org/all/202602180912.N7IZbIal-lkp@intel.com,
https://lore.kernel.org/all/202602181332.NDKD0g1P-lkp@intel.com).

If not, please run "git log --oneline" on these files and match the
historical style (capitalization, "()" after function names, etc).
Also applies to some commit logs.

I assume this series fixes some problem where VGA isn't enabled
correctly in some topology?  It wasn't obvious to me from the commit
logs, but it would be good to include that if so.

I think I did, but the () are still missing, will do another round.

It's the missing error handling if VGA cannot be enabled because a 
bridge on the way doesn't support VGA forwarding and hardwires the VGA 
bit to zero.

The i915 driver has a workaround for two internal state machines that go 
out of sync when voltage regulators are reprogrammed, so it needs to 
perform a few VGA accesses on initialization, or there is a risk of a 
bus error later when control is returned to vgacon.

This isn't a concern if VGA accesses *never* work, so we can simply skip 
it in this case, but we need to know that there was an error.

The i915 counterpart to this is

     https://patchwork.freedesktop.org/series/161721/

which changes code introduced in December, so if the pci/vgaarb patches 
are backported, that one also needs to be backported manually.

That's what the __must_check are for, the warnings they generate go away 
when the i915 patch is applied, so it probably makes sense to do that first.

So, for v3:

  - expand commit messages with the text above
  - recheck commit message style

Does it make sense to Cc stable on these?
