[PATCH 00/20] Convert all remaining drivers to GEM object functions

[PATCH 00/20] Convert all remaining drivers to GEM object functions

[Thomas Zimmermann]

The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.

Patches #1 to #18 convert DRM drivers to GEM object functions, one by one.
Each patch moves existing callbacks from struct drm_driver to an instance
of struct drm_gem_object_funcs, and sets these funcs when the GEM object is
initialized. The expection is .gem_prime_mmap. There are different ways of
how drivers implement the callback, and moving it to GEM object functions
requires a closer review for each.

Patch #19 converts xlnx to CMA helper macros. There's no apparent reason
why the driver does the GEM setup on it's own. Using CMA helper macros
adds GEM object functions implicitly.

With most of the GEM and PRIME moved to GEM object functions, related code
in struct drm_driver and in the DRM core/helpers is being removed by patch
#20.

Further testing is welcome. I tested the drivers for which I have HW
available, which are gma500, i915, nouveau, radeon and vc4. The console,
Weston and Xorg apparently work with the patches applied.

[Intel-gfx] [PATCH 00/20] Convert all remaining drivers to GEM object functions

[Thomas Zimmermann]

The GEM and PRIME related callbacks in struct drm_driver are deprecated in
favor of GEM object functions in struct drm_gem_object_funcs. This patchset
converts the remaining drivers to object functions and removes most of the
obsolete interfaces.

Patches #1 to #18 convert DRM drivers to GEM object functions, one by one.
Each patch moves existing callbacks from struct drm_driver to an instance
of struct drm_gem_object_funcs, and sets these funcs when the GEM object is
initialized. The expection is .gem_prime_mmap. There are different ways of
how drivers implement the callback, and moving it to GEM object functions
requires a closer review for each.

Patch #19 converts xlnx to CMA helper macros. There's no apparent reason
why the driver does the GEM setup on it's own. Using CMA helper macros
adds GEM object functions implicitly.

With most of the GEM and PRIME moved to GEM object functions, related code
in struct drm_driver and in the DRM core/helpers is being removed by patch
#20.

Further testing is welcome. I tested the drivers for which I have HW
available, which are gma500, i915, nouveau, radeon and vc4. The console,
Weston and Xorg apparently work with the patches applied.

[PATCH 01/20] drm/amdgpu: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in amdgpu. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 01/20] drm/amdgpu: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in amdgpu. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 03/20] drm/etnaviv: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in etnaviv. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 03/20] drm/etnaviv: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in etnaviv. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 03/20] drm/etnaviv: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in etnaviv. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[Intel-gfx] [PATCH 04/20] drm/exynos: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in exynos. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 05/20] drm/gma500: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in gma500.

[Intel-gfx] [PATCH 06/20] drm/i915: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in i915.

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in mediatek. The only exception is gem_prime_mmap,

[PATCH 07/20] drm/mediatek: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in mediatek. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 08/20] drm/msm: Introduce GEM object funcs

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in msm. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 11/20] drm/pl111: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in pl111. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 13/20] drm/rockchip: Convert to drm_gem_object_funcs

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in rockchip. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 13/20] drm/rockchip: Convert to drm_gem_object_funcs

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in rockchip. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 15/20] drm/vc4: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in vc4. The only exception is gem_prime_mmap,
which is non-trivial to convert.

per-instance callbacks in vgem. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 18/20] drm/xen: Introduce GEM object functions

[Thomas Zimmermann]

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in xen. The only exception is gem_prime_mmap,
which is non-trivial to convert.

[PATCH 19/20] drm/xlnx: Initialize DRM driver instance with CMA helper macro

[Thomas Zimmermann]

The xlnx driver uses CMA helpers with default callback functions.
Initialize the driver structure with the rsp CMA helper macro. The
driver is being converted to use GEM object functions as part of
this change.

Two callbacks, .dumb_destroy and .gem_prime_import, were initialized
to their default implementations, so they are just kept empty now.

[PATCH 19/20] drm/xlnx: Initialize DRM driver instance with CMA helper macro

[Thomas Zimmermann]

The xlnx driver uses CMA helpers with default callback functions.
Initialize the driver structure with the rsp CMA helper macro. The
driver is being converted to use GEM object functions as part of
this change.

Two callbacks, .dumb_destroy and .gem_prime_import, were initialized
to their default implementations, so they are just kept empty now.

[PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

[PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

[PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

[PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

[Intel-gfx] [PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

[PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

[Thomas Zimmermann]

Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.

What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.

While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.

Re: [PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

struct drm_gem_object_funcs
---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.

If yes, then delete it too.

Re: [PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

After this following entry in todo.rst is done?

"
struct drm_gem_object_funcs
---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
"

If yes, then delete it too.

---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.

If yes, then delete it too.

Re: [Intel-gfx] [PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

After this following entry in todo.rst is done?

"
struct drm_gem_object_funcs
---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
"

If yes, then delete it too.

Re: [PATCH 20/20] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver

After this following entry in todo.rst is done?

"
struct drm_gem_object_funcs
---------------------------

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.

We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
"

If yes, then delete it too.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

This sounds like it got fixed in the recent CMA clean-up series. There
are CMA initializer macros for drivers with and without vmap. I have to
take a closer look, but I think it can be removed.

Thanks for bringing this up.

This should only say that .gem_prime_mmap() is left in struct
drm_drivers for conversion.

Can we please have naming consistent and name it as

but starting with xen_drm_front_ as the rest of exported functions?

Can we please have naming consistent and name it as

xen_drm_front_drv_free_object_unlocked or any other name if this seems to be too long,

but starting with xen_drm_front_ as the rest of exported functions?

With this,

Thank you,

The only effective change here is

-	.gem_prime_import_sg_table	= drm_gem_cma_prime_import_sg_table,
-	.gem_prime_mmap			= drm_gem_cma_prime_mmap,
+	.gem_prime_import_sg_table	= drm_gem_cma_prime_import_sg_table_vmap,
+	.gem_prime_mmap			= drm_gem_prime_mmap,

The change is significant, and I have a hard time following the code to
verify that it's correct, or if it's an undesired side effect. If it's
correct, could the change be mentioned in the commit message, with at
least a brief explanation of why this is correct, and what the
consequences here ?

I think this is a mistake that I didn't notice. Thanks for spotting it.
Initializing the driver structure
DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE should fix it. I'll change this
for the patch's next revision.

Or otherwise we would have a reference counting issue.

Those shouldn't have a GEM object in the first place.

Or otherwise we would have a reference counting issue.
