drm: Remove dummy agp ioctl wrappers

2015-09-30T08:49:22+00:00

They're only used in the drm ioctl table, and there they're excluded
when AGP support is disabled. So this is just dead code ripe for
removal.

drm: Remove __OS_HAS_AGP

2015-09-30T08:44:48+00:00

We already express the drm/agp depencies correctly in Kconfig, so we
can rip this remnant from the shared drm core days.

Aside: Pretty much all the #ifdefs in radeon/nouveau could be killed
if ttm would provide dummy functions. I'm not going to volunteer for
that though.

v2: Use IS_ENABLED(CONFIG_AGP) as suggested by Ville

v3: Polish from Ville's review.

drm: move remaining includes in drmP.h to the top

2014-09-10T07:42:03+00:00

Including headers somewhere else but at the top is ugly, deprecated and
was used in early days only to speed up compile-times. Those days are
over. Make headers independent and then move the inclusions to the top.

drm: move __OS_HAS_AGP into drm_agpsupport.h

2014-09-10T07:41:03+00:00

With drm_memory.h gone, there is no header left that uses __OS_HAS_AGP.
Move it into drm_agpsupport.h (which is itself included from drmP.h) to
hide it harder from public eyes.

drm: move AGP definitions harder

2014-09-10T07:40:11+00:00

Move drm_agp_head to drm_agpsupport.h and drm_agp_mem into drm_legacy.h.
Unfortunately, drivers still heavily access drm_agp_head so we cannot
move it to drm_legacy.h. However, at least it's no longer visible in
drmP.h now (it's directly included from it, though).

drm: rip out DRM_AGP_MEM and DRM_AGP_KERN

2013-12-18T01:32:55+00:00

The  header provides dummy functions and
fallbacks, so no need for screaming macros.

drm: inline drm_agp_destroy

2013-12-18T01:23:46+00:00

Wrapping a kfree is pointless.

v2: Add a comment to the kerneldoc for drm_agp_init to explain where
the kfree happens as requested by David. Note that for modeset drivers
agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop
and drivers must call drm_agp_release on their own. Which they all
seem to do properly.

drm: rip out drm_core_has_AGP

2013-12-18T01:20:04+00:00

Most place actually want to just check for dev->agp (most do, but a
few don't so this fixes a few potential NULL derefs). The only
exception is the agp init code which should check for the AGP driver
feature flag.

drm: provide agp dummies for CONFIG_AGP=n

2013-08-08T21:22:11+00:00

We currently rely on gcc dead-code elimination so the drm_agp_* helpers
are not called if drm_core_has_AGP() is false. That's ugly as hell so
provide "static inline" dummies for the case that AGP is disabled.

Fixes a build-regression introduced by:
