Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v3: - Don't touch remove_conflicting_framebuffers v2: - Fixed PTR_ERR issue mentioned by kbuild bot Cc: Fengguang Wu <fengguang.wu@xxxxxxxxx> Cc: Alex Deucher <alexander.deucher@xxxxxxx> Cc: Oded Gabbay <oded.gabbay@xxxxxxxxx> Cc: "Christian König" <christian.koenig@xxxxxxx> Signed-off-by: Archit Taneja <architt@xxxxxxxxxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c | 45 +++++++++++----------------------- 1 file changed, 14 insertions(+), 31 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c index c1645d2..81b8212 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c @@ -53,9 +53,9 @@ static struct fb_ops amdgpufb_ops = { .owner = THIS_MODULE, .fb_check_var = drm_fb_helper_check_var, .fb_set_par = drm_fb_helper_set_par, - .fb_fillrect = cfb_fillrect, - .fb_copyarea = cfb_copyarea, - .fb_imageblit = cfb_imageblit, + .fb_fillrect = drm_fb_helper_cfb_fillrect, + .fb_copyarea = drm_fb_helper_cfb_copyarea, + .fb_imageblit = drm_fb_helper_cfb_imageblit, .fb_pan_display = drm_fb_helper_pan_display, .fb_blank = drm_fb_helper_blank, .fb_setcmap = drm_fb_helper_setcmap, @@ -179,7 +179,6 @@ static int amdgpufb_create(struct drm_fb_helper *helper, struct drm_mode_fb_cmd2 mode_cmd; struct drm_gem_object *gobj = NULL; struct amdgpu_bo *rbo = NULL; - struct device *device = &adev->pdev->dev; int ret; unsigned long tmp; @@ -201,9 +200,9 @@ static int amdgpufb_create(struct drm_fb_helper *helper, rbo = gem_to_amdgpu_bo(gobj); /* okay we have an object now allocate the framebuffer */ - info = framebuffer_alloc(0, device); - if (info == NULL) { - ret = -ENOMEM; + info = drm_fb_helper_alloc_fbi(helper); + if (IS_ERR(info)) { + ret = PTR_ERR(info); goto out_unref; } @@ -212,14 +211,13 @@ static int amdgpufb_create(struct drm_fb_helper *helper, ret = amdgpu_framebuffer_init(adev->ddev, &rfbdev->rfb, &mode_cmd, gobj); if (ret) { DRM_ERROR("failed to initialize framebuffer %d\n", ret); - goto out_unref; + goto out_destroy_fbi; } fb = &rfbdev->rfb.base; /* setup helper */ rfbdev->helper.fb = fb; - rfbdev->helper.fbdev = info; memset_io(rbo->kptr, 0x0, amdgpu_bo_size(rbo)); @@ -239,11 +237,6 @@ static int amdgpufb_create(struct drm_fb_helper *helper, drm_fb_helper_fill_var(info, &rfbdev->helper, sizes->fb_width, sizes->fb_height); /* setup aperture base/size for vesafb takeover */ - info->apertures = alloc_apertures(1); - if (!info->apertures) { - ret = -ENOMEM; - goto out_unref; - } info->apertures->ranges[0].base = adev->ddev->mode_config.fb_base; info->apertures->ranges[0].size = adev->mc.aper_size; @@ -251,13 +244,7 @@ static int amdgpufb_create(struct drm_fb_helper *helper, if (info->screen_base == NULL) { ret = -ENOSPC; - goto out_unref; - } - - ret = fb_alloc_cmap(&info->cmap, 256, 0); - if (ret) { - ret = -ENOMEM; - goto out_unref; + goto out_destroy_fbi; } DRM_INFO("fb mappable at 0x%lX\n", info->fix.smem_start); @@ -269,6 +256,8 @@ static int amdgpufb_create(struct drm_fb_helper *helper, vga_switcheroo_client_fb_set(adev->ddev->pdev, info); return 0; +out_destroy_fbi: + drm_fb_helper_release_fbi(helper); out_unref: if (rbo) { @@ -290,17 +279,10 @@ void amdgpu_fb_output_poll_changed(struct amdgpu_device *adev) static int amdgpu_fbdev_destroy(struct drm_device *dev, struct amdgpu_fbdev *rfbdev) { - struct fb_info *info; struct amdgpu_framebuffer *rfb = &rfbdev->rfb; - if (rfbdev->helper.fbdev) { - info = rfbdev->helper.fbdev; - - unregister_framebuffer(info); - if (info->cmap.len) - fb_dealloc_cmap(&info->cmap); - framebuffer_release(info); - } + drm_fb_helper_unregister_fbi(&rfbdev->helper); + drm_fb_helper_release_fbi(&rfbdev->helper); if (rfb->obj) { amdgpufb_destroy_pinned_object(rfb->obj); @@ -395,7 +377,8 @@ void amdgpu_fbdev_fini(struct amdgpu_device *adev) void amdgpu_fbdev_set_suspend(struct amdgpu_device *adev, int state) { if (adev->mode_info.rfbdev) - fb_set_suspend(adev->mode_info.rfbdev->helper.fbdev, state); + drm_fb_helper_set_suspend(&adev->mode_info.rfbdev->helper, + state); } int amdgpu_fbdev_total_size(struct amdgpu_device *adev) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
