[v6,1/3] i915/gvt: Introduce the mmio table to support VFIO new mdev API

Commit Message

Zhi Wang Feb. 8, 2022, 11:11 a.m. UTC

From: Zhi Wang <[e-mail]>

To support the new mdev interfaces and the re-factor patches from
Christoph, which moves the GVT-g code into a dedicated module, the GVT-g
initialization path has to be separated into two phases:

a) Early initialization.

The early initialization of GVT requires to be done when loading i915.
Mostly it's because the initial clean HW state needs to be saved before
i915 touches the HW.

b) Late initalization.

This phases of initalization will setup the rest components of GVT-g,
which can be done later when the dedicated module is being loaded.

v6:

- Move the mmio_table.c into i915. (Christoph)
- Keep init_device_info and related structures in GVT-g. (Christoph)
- Refine the callbacks of the iterator. (Christoph)
- Move the flags of MMIO register defination to GVT-g. (Chrsitoph)
- Move the mmio block handling to GVT-g.

v5:

- Re-design the mmio table framework. (Christoph)

v4:

- Fix the errors of patch checking scripts.

v3:

- Fix the errors when CONFIG_DRM_I915_WERROR is turned on. (Jani)

v2:

- Implement a mmio table instead of generating it by marco in i915. (Jani)

What's the baseline for this series?

Please use minimal includes. Looks like linux/types.h is enough. Please
also put the includes before the forward declarations.

If these really need to be in a header in i915/, I think they need to be
longer with some namespacing or something. I do wish these could be
hidden though.

We're heavily transitioning towards having a corresponding .h for each
.c instead of catch all headers. It's still a work in progress, but I'd
prefer having the declarations for stuff in intel_gvt_mmio_table.c
placed in intel_gvt_mmio_table.h, and named accordingly. Like I
suggested in my previous mails.

Stubs need to be static inlines.

I'm fine with cleaning this up in follow-up, provided the follow-up
actually happens! ;)

I agree that's the correct way for not exporting this to i915 by just organizing them in the functions, like what you said.
But I guess it's also matter of time and schedule as well. If we go that direction, it might take longer time for coding as
this is a big re-factor. Also, we need our QA to do another full test run. That needs to be considered. (If we are ok with that)

Besides, we have to have a methodology to make sure everything is the same as before.
Currently I am comparing the numbers of tracked mmio and the mmio snapshot. It would be nice to have more insight. :)

Thanks,
Zhi.

Can't speak for the status of the series, but for drm the deadline for
changes headed for the merge window is around -rc5/-rc6 timeframe
i.e. this has already missed the upcoming merge window.

BR,

I was actually testing it for almost two weeks, but still I met some hang and I was trying to figure where the problem is as this is quite a big change. Let's see if I can figure it out this week.

Thanks,
Zhi.
