From: Marius Vlad <marius.vlad0@xxxxxxxxx> Currently driver-specific ioctls have to be declared static and are confined to DRM core driver. This patch series provides the means to remove those constrains and allow to register driver-specific ioctls dynamically by keeping a list of registered ioctls in struct drm_driver, then each component of the driver can then register its own specific ioctls using this interface. The driver must assign ioctl_register/ioctl_deregister in its drm_driver structure in order to make use of it. While SoC drivers benefit the most from this approach (by not polluting DRM core driver and allowing sub drivers to implement and register driver-specific ioctls dynamically), further patches shows how easy is to convert drm/i915 to this approach by registering GEM and perf ioctls separately. Marius Vlad (4): drm/gpu: Support registering driver-specific ioctls dynamically drm/i915: Convert i915 to use ioctl_register/ioctl_deregister. drm/i915: Register perf_ ioctls directly in i915_perf file. drm/i915: Register GEM ioctls directly in i915_gem file. drivers/gpu/drm/drm_drv.c | 1 + drivers/gpu/drm/drm_ioctl.c | 99 ++++++++++++++++++++++++++++++++++-- drivers/gpu/drm/i915/i915_drv.c | 107 +++++++++++++++------------------------ drivers/gpu/drm/i915/i915_gem.c | 52 +++++++++++++++++++ drivers/gpu/drm/i915/i915_perf.c | 21 ++++++++ include/drm/drm_drv.h | 34 +++++++++++++ include/drm/drm_ioctl.h | 6 +++ 7 files changed, 249 insertions(+), 71 deletions(-) -- 2.9.3 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
