Framebuffer memory is allocated via vzalloc() from non-contiguous physical pages. The physical framebuffer start address is therefore meaningless. Do not set it.
The value is not used within the kernel and only exported to userspace on dedicated ARM configs. No functional change is expected. v2: - refer to vzalloc() in commit message (Javier) Signed-off-by: Thomas Zimmermann <[email protected]> Fixes: a5b44c4adb16 ("drm/fbdev-generic: Always use shadow buffering") Cc: Thomas Zimmermann <[email protected]> Cc: Javier Martinez Canillas <[email protected]> Cc: Zack Rusin <[email protected]> Cc: Maarten Lankhorst <[email protected]> Cc: Maxime Ripard <[email protected]> Cc: <[email protected]> # v6.4+ Reviewed-by: Javier Martinez Canillas <[email protected]> Reviewed-by: Zack Rusin <[email protected]> Reviewed-by: Sui Jingfeng <[email protected]> Tested-by: Sui Jingfeng <[email protected]> --- drivers/gpu/drm/drm_fbdev_generic.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/gpu/drm/drm_fbdev_generic.c b/drivers/gpu/drm/drm_fbdev_generic.c index be357f926faec..97e579c33d84a 100644 --- a/drivers/gpu/drm/drm_fbdev_generic.c +++ b/drivers/gpu/drm/drm_fbdev_generic.c @@ -113,7 +113,6 @@ static int drm_fbdev_generic_helper_fb_probe(struct drm_fb_helper *fb_helper, /* screen */ info->flags |= FBINFO_VIRTFB | FBINFO_READS_FAST; info->screen_buffer = screen_buffer; - info->fix.smem_start = page_to_phys(vmalloc_to_page(info->screen_buffer)); info->fix.smem_len = screen_size; /* deferred I/O */ -- 2.44.0
