drm/shmobile: Use drm_module_platform_driver() to register the driver

2022-01-27T18:15:47+00:00

The macro calls to a DRM specific platform driver init handler that checks whether the driver is allowed to be registered or not. Signed-off-by: Javier Martinez Canillas Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20211217003752.3946210-15-javierm@redhat.com

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03+00:00

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting KMS helpers and CMA will now automatically enable CMA KMS helpers. Some drivers' Kconfig files did not correctly select KMS or CMA helpers. Fix this as part of the change.

drm/shmobile: Make use of the helper function devm_platform_ioremap_resource()

drm/shmobile: Convert to Linux IRQ interfaces

2021-07-25T09:01:12+00:00

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it. v3: * return error if (ret < 0) (Geert) * remove duplicate error message (Geert) v2: * handle errors in platform_get_irq() (Geert, Sergei) * store IRQ number in struct shmob_drm_device (Laurent) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20210720080941.23646-1-tzimmermann@suse.de

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - 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. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. 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). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg Cc: kernel test robot Acked-by: Maxime Ripard Reviewed-by: Alex Deucher Signed-off-by: Daniel Vetter Cc: Sam Ravnborg Cc: Dave Airlie Cc: Gerd Hoffmann Cc: virtualization@lists.linux-foundation.org Cc: Harry Wentland Cc: Leo Li Cc: Alex Deucher Cc: Christian König Cc: Eric Anholt Cc: Maxime Ripard Cc: Ben Skeggs Cc: nouveau@lists.freedesktop.org Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20201104100425.1922351-5-daniel.vetter@ffwll.ch

drm/shmobile: Set GEM CMA functions with DRM_GEM_CMA_DRIVER_OPS

DRM_GEM_CMA_DRIVER_OPS sets the functions in struct drm_driver to their defaults. No functional changes are made. Signed-off-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-33-tzimmermann@suse.de

drm/shmobile: Use GEM CMA object functions

2020-06-10T07:05:12+00:00

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which allocates the object and sets CMA's default object functions. Corresponding callbacks in struct drm_driver are cleared. No functional changes are made. Driver and object-function instances use the same callback functions, with the exception of vunmap. The implementation of vunmap is empty and left out in CMA's default object functions. v3: * convert to DRIVER_OPS macro in a separate patch Signed-off-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200605073247.4057-32-tzimmermann@suse.de

drm/shmob: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:06:05+00:00

It's right above the drm_dev_put(). This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). Aside: Another driver with a bit much devm_kzalloc, which should probably use drmm_kzalloc instead ... v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas) Cc: Sam Ravnborg Cc: Thomas Zimmermann Reviewed-by: Laurent Pinchart (v2) Cc: Laurent Pinchart Signed-off-by: Daniel Vetter Cc: Laurent Pinchart Cc: Kieran Bingham Cc: linux-renesas-soc@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20200323144950.3018436-40-daniel.vetter@ffwll.ch
