From 5b38e7475e3dc54c1091ee169fd050b3f10461fc Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 29 Jan 2019 11:42:46 +0100 Subject: [PATCH] drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install If a non-legacy driver calls these it's valid to assume there is interrupt support. The flag is really only needed for legacy drivers, which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL legacy IOCTL. Also remove all the flag usage from non-legacy drivers. v2: Review from Emil: - improve commit message - I forgot hibmc, fix that Cc: linux-arm-kernel@lists.infradead.org Cc: intel-gfx@lists.freedesktop.org Cc: linux-amlogic@lists.infradead.org Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Cc: virtualization@lists.linux-foundation.org Cc: spice-devel@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Cc: linux-renesas-soc@vger.kernel.org Reviewed-by: Emil Velikov Reviewed-by: Sam Ravnborg Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190129104248.26607-1-daniel.vetter@ffwll.ch --- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 2 +- drivers/gpu/drm/arm/hdlcd_drv.c | 2 +- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c | 2 +- drivers/gpu/drm/drm_irq.c | 6 ------ drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_drv.c | 2 +- drivers/gpu/drm/gma500/psb_drv.c | 2 +- drivers/gpu/drm/hisilicon/hibmc/hibmc_drm_drv.c | 3 +-- drivers/gpu/drm/i915/i915_drv.c | 2 +- drivers/gpu/drm/meson/meson_drv.c | 2 +- drivers/gpu/drm/msm/msm_drv.c | 3 +-- drivers/gpu/drm/mxsfb/mxsfb_drv.c | 3 +-- drivers/gpu/drm/qxl/qxl_drv.c | 2 +- drivers/gpu/drm/radeon/radeon_drv.c | 2 +- drivers/gpu/drm/shmobile/shmob_drm_drv.c | 2 +- drivers/gpu/drm/tilcdc/tilcdc_drv.c | 2 +- drivers/gpu/drm/vc4/vc4_drv.c | 1 - drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 2 +- drivers/staging/vboxvideo/vbox_drv.c | 2 +- 18 files changed, 16 insertions(+), 26 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index 0c22bae..2250241 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -1189,7 +1189,7 @@ amdgpu_get_crtc_scanout_position(struct drm_device *dev, unsigned int pipe, static struct drm_driver kms_driver = { .driver_features = DRIVER_USE_AGP | DRIVER_ATOMIC | - DRIVER_HAVE_IRQ | DRIVER_IRQ_SHARED | DRIVER_GEM | + DRIVER_IRQ_SHARED | DRIVER_GEM | DRIVER_PRIME | DRIVER_RENDER | DRIVER_MODESET | DRIVER_SYNCOBJ, .load = amdgpu_driver_load_kms, .open = amdgpu_driver_open_kms, diff --git a/drivers/gpu/drm/arm/hdlcd_drv.c b/drivers/gpu/drm/arm/hdlcd_drv.c index e68935b..8fc0b88 100644 --- a/drivers/gpu/drm/arm/hdlcd_drv.c +++ b/drivers/gpu/drm/arm/hdlcd_drv.c @@ -229,7 +229,7 @@ static int hdlcd_debugfs_init(struct drm_minor *minor) DEFINE_DRM_GEM_CMA_FOPS(fops);
