drm/core: clean up references to drm_dev_unref()

2017-09-27T08:53:12+00:00

This is a continuation of a previous commit ("drm: introduce drm_dev_{get/put}
functions") to replace all references to drm_dev_unref() in drm core files with
drm_dev_put().

drm/pci: Deprecate drm_pci_init/exit completely

2017-06-20T08:41:03+00:00

The magic switching between proper pci driver and shadow-attach isn't
useful anymore since there's no ums+kms drivers left. Let's split this
up properly, calling pci_register_driver for kms drivers and renaming
the shadow-attach init to drm_legacy_pci_init/exit.

drm: Remove drm_driver->set_busid hook

2017-06-20T08:40:49+00:00

The only special-case is pci devices, and we can easily handle this in
the core. Do so and drop a pile of boilerplate from drivers.

drm: Extract drm_pci.h

2017-03-09T15:18:02+00:00

Just another step in finally making drmP.h obsolete.

drm: remove device_is_agp callback

2017-01-26T09:45:14+00:00

With that the drm_pci_device_is_agp function becomes trivial, so
inline that too. And while at it, move the drm_pci_agp_destroy
declaration into drm-internal.h, since it's not used by drivers.

drm/core: Use recommened kerneldoc for struct member refs

2017-01-25T15:22:42+00:00

I just learned that &struct_name.member_name works and looks pretty
even. It doesn't (yet) link to the member directly though, which would
be really good for big structures or vfunc tables (where the
per-member kerneldoc tends to be long).

Also some minor drive-by polish where it makes sense, I read a lot
of docs ...

drm: Deduplicate driver initialization message

2016-12-30T11:37:39+00:00

Several DRM drivers print the same initialization message right after
drm_dev_register, so move that to common code.  The exception is i915,
which uses its own register handle, so let it keep its own message.

Notice that this was tested only with Exynos, but looks simple enough
for the other drivers.

drm: Don't swallow error codes in drm_dev_alloc()

2016-09-22T11:03:48+00:00

There are many reasons other than ENOMEM that drm_dev_init() can
fail. Return ERR_PTR rather than NULL to be able to distinguish
these in the caller.

drm: Used DRM_LEGACY for all legacy functions

2016-08-08T08:05:23+00:00

Except for nouveau, only legacy drivers need this really. And nouveau
is already marked up with DRIVER_KMS_LEGACY_CONTEXT as the special
case.

I've tried to be careful to leave everything related to modeset still
using the DRIVER_MODESET flag. Otherwise it's a direct replacement of
!DRIVER_MODESET with DRIVER_LEGACY checks. Also helps readability
since fewer negative checks overall.

drm: Nuke SET_UNIQUE ioctl

2016-06-21T19:43:46+00:00

Ever since

commit 2e1868b560315a8b20d688e646c489a5ad93eeae
Author: Eric Anholt 
Date:   Wed Jun 16 09:25:21 2004 +0000

    DRI trunk-20040613 import

the X server supports drm 1.1, thus doesn't call call libdrm's
drmSetBusid - the sole user of this ioctl. When reviewing this note
that for hilarity both the kernel-internal functions (set_busid) and
the libdrm wrapper (drmSetBusid) have names not matching this ioctl
(SET_UNIQUE).
