[PATCH 0/8] More header rework

[PATCH 0/8] More header rework

[Daniel Vetter]

So the main part here is the extraction of drm_gem.h. With a bit of prep work to
ditch the legacy mmap stuff out of gem/ttm drivers. Plus a few random pieces of
leftover cleanup that I've missed in my earlier header rework or just stumbled
over while working on this.

With this drmP.h really starts to look rather sane (it's just 1kloc now),
besides maybe the uppercase P in it's name and the massive list of headers it
includes.

As usual comments and review highly welcome. I'll probably try to still throw
this at Dave for 3.18 and see whether he rejects it or not. Otherwise no harm to
postpone this until 3.19 (but David Herrrmann said he's got more work on his
todo in this area, so merging earlier might avoid conflicts).

Cheers, Daniel

[PATCH 1/8] drm/<ttm-based-drivers>: Don't call drm_mmap

[Daniel Vetter]

Really, the legacy buffer api should be dead, especially for all these
newfangled drivers. I suspect this is copypasta from the transitioning
days, which probably originated in radeon.

Yeah, I hope no-one ever used DMA-mmap or BUFS-mmap on those drivers..
otherwise, we can still revert it in special cases (or just break this
legacy stuff..).

I would say NAK as i am pretty sure this break radeon UMS code path.
Of course if we have the go ahead to nuke radeon UMS i am more than
happy.

radeon_drv.c says:
        driver_old.fops.mmap == drm_mmap;

..so I don't understand why that would break UMS? Do you use KMS mixed
with UMS? radeon_mmap() is only used by radeon_driver_kms_fops, which
is only used by kms_driver. UMS (which I understand as non-KMS in
radeon case) should not be affected by this.

Thanks
David

Oh this might be an heritage of old code in my mind when we had old user
space running on top of KMS, more as a prototype stage and maybe also at
one point the plan was to share the same mmap function so that old code
could use new code cs ioctl.

So yeah this can be nuke sorry for the noise.

[PATCH 2/8] drm/gem: Don't call drm_mmap from drm_gem_mmap

[Daniel Vetter]

The only user I could dig out was i915 back when ums+gem was still a
thing. But we've just very much killed that, and even when someone
screams about that we should resurrect that with a special hack
(wrapping drm_gem_mmap) in i915, not in the core code.

So good riddance to another entry point of the legacy buffer mapping
code.

Agreed! Drivers should just add the hacks themselves if there is
user-space that needs it. Same as for patch #1:

[PATCH 3/8] drm: move drm_mmap to <drm/drm_legacy.h>

[Daniel Vetter]

Now that we've removed the copypasted users in gem/ttm we can
relegate the legacy buffer mapping support to where it belongs.
Also give it the proper drm_legacy_ prefix.

While at it statify drm_mmap_locked, somehow I've missed that in my
previous header rework.

[PATCH 4/8] drm: Move drm_vm_open_locked into drm_internal.h

[Daniel Vetter]

Leftover from my previous header cleanup.

This depends upon the patch to rework exynos mmap support, otherwise
it'll break exynos.

What patch do you mean? I cannot see any users of drm_vm_open_locked()
anywhere besides drm_gem.c and drm_vm.c, (branch drm-next).

Only since exynos-next was pulled in yesterday, which is why I've now sent
these out. I'll reword the commit message to reflect this.

Re: [PATCH 6/8] drm: Move internal debugfs functions to drm_internal.h
