[PATCH 1/3] drm: Expose a method for creating anonymous struct file around drm_minor

[PATCH 1/3] drm: Expose a method for creating anonymous struct file around drm_minor

[Chris Wilson]

Sometimes we need to create a struct file to wrap a drm_device, as it
the user were to have opened /dev/dri/card0 but to do so anonymously
(i.e. for internal use). Provide a utility method to create a struct
file with the drm_device->driver.fops, that wrap the drm_device.

[Intel-gfx] [PATCH 2/3] drm/i915/selftests: Wrap vm_mmap() around GEM objects

[Chris Wilson]

Provide a utility function to create a vma corresponding to an mmap() of
our device. And use it to exercise the equivalent of userspace
performing a GTT mmap of our objects.

[PATCH 3/3] drm/prime: Use anon_drm_getfile() for an internal drm struct file

[Chris Wilson]

Currently the drm_prime mmap fallback uses a mock struct file to provide
the file pointer into the backend mmap routine. Now that we can create
fully fledged anonymous struct file around the drm device, put it to
use.

For proper internal access we already have drm_client_open, so I think
this has limited (but good use) in selftests only. So
EXPORT_SYMBOL_FOR_TESTS_ONLY plus maybe a clearer name for the intended
use like drm_file_mock_open?

Aside from this I like.

For proper internal access we already have drm_client_open, so I think
this has limited (but good use) in selftests only. So
EXPORT_SYMBOL_FOR_TESTS_ONLY plus maybe a clearer name for the intended
use like drm_file_mock_open?

Aside from this I like.

obj->funcs->mmap is the new way of doing this (and hopefully finally
something clean), I'd really like to retire the below hack outright.

Plus I'm not sure why you need an anon inode here? If a driver needs this
for unmap_mapping_range or similar I think it'd be better to try and make
something work cleanly for obj->funcs->mmap.

I found the example in drm_gem_prime_mmap() that was doing the same trick,
and the trick of being able to instantiate new struct file and install a
fd whenever seems like it will come in handy... Just lacking the third
user at the moment to claim generality.

I found the example in drm_gem_prime_mmap() that was doing the same trick,
and the trick of being able to instantiate new struct file and install a
fd whenever seems like it will come in handy... Just lacking the third
user at the moment to claim generality.

The closest example I found in the spirit of creating a new drm_device
struct file and installing it is drm_mode_create_lease_ioctl() that uses
file_clone_open() for this purpose. The argument there would be whether
cloning the (file->f_path, file->f_flags, file->f_cred) is appropriate
versus an anonymous inode. I think cloning the credentials seems correct
for leasing.

It's faking one currently. If the fake is not good enough, you are
playing whack-a-mole until you finally do create a fully fledged file.

If you are going to the trouble of having to create a struct file to
provide to the fallback routines, might as well avoid stinky code :)

We're currently not faking the inode at all, we're just using the one
that comes with the dma-buf. So distinct from the drm_device file, and
hence unmap_mapping_range won't work (or at least doing that on the
drm_device inode wont shoot down the ptes for redirected dma-buf
mmaps). obj->funcs->mmap has the same issue.

But since all current users of this don't expect unmap_mapping_range
to work correctly, it's not an real issue. If that changes then imo we
should fix up the obj->funcs->mmap path to have the correct inode, not
the deprecated path you're updating here. But since there's no patch 4
in this series to start using this for i915 or someone else, I'm not
seeing the point.

Or am I blind? At least slightly confused,

Hm ... I think we want the clone for this one here too. Otherwise we
get the wrong inode, and then unmap_mapping_range wont work correctly,
and we cant use this for selftests. That's the only case where I think
we do actually need the file/inode to be functional. For anything else
the drm_client internal api gets away without the file/inode stuff.

There's a bug in anon_drm_inode() in that it requires an extra:

+       /* Everyone shares a single global address space */
+       file->f_mapping = dev->anon_inode->i_mapping;

I'm up to 5 patches now, but only i915/selftests & this here fallback as
direct users.

There's a bug in anon_drm_inode() in that it requires an extra:

+       /* Everyone shares a single global address space */
+       file->f_mapping = dev->anon_inode->i_mapping;

I'm up to 5 patches now, but only i915/selftests & this here fallback as
direct users.
