With only the kms driver left, we can fold this in. This means we need to move the ioctl table, which means one additional ioctl must be defined in headers.
Also there's a conflict between the radeon_init macro and the module init function, so rename the module functions to avoid that.

This means some very few #ifdef in code, but it allows us to enlist the compiler to make sure this stuff isn't used anymore.
More important, only legacy drivers change drm_device (for the legacy_dev_list shadow attach management), therefore this is prep to allow modern drivers to have a const driver struct. Which is nice, because there's a ton of function pointers in there.

Some of the conditionals does not help the readability :-( But they are better than exposing legacy stuff to non-legacy drivers. And it is a suprising fews that are required. So legacy seems to be factored out well from the core.

Sort of related: the implementation for KMS and UMS devices is more and more distinct from each other. Did you ever consider going for separate legacy helpers instead of mixing-in all these ifdefs?

This means some very few #ifdef in code, but it allows us to enlist the compiler to make sure this stuff isn't used anymore.
More important, only legacy drivers change drm_device (for the legacy_dev_list shadow attach management), therefore this is prep to allow modern drivers to have a const driver struct. Which is nice, because there's a ton of function pointers in there.

Sort of related: the implementation for KMS and UMS devices is more and more distinct from each other. Did you ever consider going for separate legacy helpers instead of mixing-in all these ifdefs?
I think we could split out drm_pci_legacy.c. Everything else is already split out into separate files and made optional at the Makefile level, it's really only in oddball places around the shared drm_device where there's any #ifdef at all. -Daniel

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else is way too much).

Hi Daniel.

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure.
My grepping turned up the following: - The example in drm_drv needs to be updated - legacy drivers, that are obviously not converted - but worth to mention above - arc is not converted and it is not legacy Maybe you have it covered in your big arc conversion patch?
With the above fixed: Acked-by: Sam Ravnborg sam@ravnborg.org
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else is way too much).

Hmm, so we have more than one Daniel in play here. Both the Intel guy and the ffwll guy - looks funny.

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure.
My grepping turned up the following:
- The example in drm_drv needs to be updated
- legacy drivers, that are obviously not converted - but worth to mention above
- arc is not converted and it is not legacy Maybe you have it covered in your big arc conversion patch?
Yeah I excluded that one because it's stuck behind my arcpgu tinification. I'll update the commit message to mention that with your other suggestions. -Daniel
With the above fixed: Acked-by: Sam Ravnborg sam@ravnborg.org
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else is way too much).

Hi
Am 23.10.20 um 14:28 schrieb Daniel Vetter:
Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else is way too much).

Oh please no. That's a huge patch for no apparent reason. Can you break this up?

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else is way too much).

Oh please no. That's a huge patch for no apparent reason. Can you break this up?
Function pointer tables are high value targets, making them const allows the compiler to move them into the read-only section and the kernel to protect them from stray writes. That helps against exploits, especially for a function table which userspace pretty much directly calls. So that's why making stuff const is important in the kernel.
Now I didn't feel like splitting this up per-driver because it's a bit too much trivial change, plus it' would take weeks to get all the acks for every piece. But if you promise you'll go and ack them all I can inflate this up to 11 and dump a 60+ patch set on dri-devel :-)
Cheers, Daniel
