The following happened when migrating an old fbdev driver to DRM: The Integrator/CP PL111 supports 16BPP but only ARGB1555/ABGR1555 or XRGB1555/XBGR1555 i.e. the maximum depth is 15. This makes the initialization of the framebuffer fail since the code in drm_fb_helper_single_fb_probe() assigns the same value to sizes.surface_bpp and sizes.surface_depth. I.e. it simply assumes a 1-to-1 mapping between BPP and depth, which is true in most cases but not for this hardware that only support odd formats. To support the odd case of a driver supporting 16BPP with only 15 bits of depth, this patch will make the code loop over the formats supported on the primary plane on each CRTC managed by the FB helper and cap the depth to the maximum supported on any primary plane. On the PL110 Integrator, this makes drm_mode_legacy_fb_format() select DRM_FORMAT_XRGB1555 which is acceptable for this driver, and thus we get framebuffer, penguin and console on the Integrator/CP.

Fill out the AVI infoframe quantization range bits using drm_hdmi_avi_infoframe_quant_range() instead of hand rolling it. This changes the behaviour slightly as drm_hdmi_avi_infoframe_quant_range() will set a non-zero Q bit even when QS==0 iff the Q bit matched the default quantization range for the given mode. This matches the recommendation in HDMI 2.0 and is allowed even before that.

The gem drivers use shmemfs to allocate backing storage for gem objects. On Samsung Chromebook Plus, the drm/rockchip driver may call rockchip_gem_get_pages -> drm_gem_get_pages -> shmem_read_mapping_page to pin a lot of pages, breaking the page reclaim mechanism and causing oom-killer invocation. E.g. when the size of a zone is 3.9 GiB, the inactive_ratio is 5. If active_anon / inactive_anon < 5 and all pages in the inactive_anon lru are pinned, page reclaim would keep scanning inactive_anon lru without reclaiming memory. It breaks page reclaim when the rockchip driver only pins about 1/6 of the anon lru pages. Mark these pinned pages as unevictable to avoid the premature oom-killer invocation.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

After drm_fb_helper_fbdev_setup calls drm_fb_helper_init, "dev->fb_helper" will be initialized (and thus drm_fb_helper_fini will have some effect). After that, drm_fb_helper_initial_config is called which may call the "fb_probe" driver callback. This driver callback may call drm_fb_helper_defio_init (as is done by drm_fb_helper_generic_probe) or set a framebuffer (as is done by bochs) as documented. These are normally cleaned up on exit by drm_fb_helper_fbdev_teardown which also calls drm_fb_helper_fini. If an error occurs after "fb_probe", but before setup is complete, then calling just drm_fb_helper_fini will leak resources. This was triggered by df2052cc ("bochs: convert to drm_fb_helper_fbdev_setup/teardown"): [ 50.008030] bochsdrmfb: enable CONFIG_FB_LITTLE_ENDIAN to support this framebuffer [ 50.009436] bochs-drm 0000:00:02.0: [drm:drm_fb_helper_fbdev_setup] *ERROR* fbdev: Failed to set configuration (ret=-38) [ 50.011456] [drm] Initialized bochs-drm 1.0.0 20130925 for 0000:00:02.0 on minor 2 [ 50.013604] WARNING: CPU: 1 PID: 1 at drivers/gpu/drm/drm_mode_config.c:477 drm_mode_config_cleanup+0x280/0x2a0 [ 50.016175] CPU: 1 PID: 1 Comm: swapper/0 Tainted: G T 4.20.0-rc7 #1 [ 50.017732] EIP: drm_mode_config_cleanup+0x280/0x2a0 ...

If register_framebuffer() fails during fbdev setup we will leak the framebuffer, the GEM buffer and the shadow buffer for defio. This is because drm_fb_helper_fbdev_setup() just calls drm_fb_helper_fini() on error not taking into account that register_framebuffer() can fail. Since the generic emulation uses DRM client for its framebuffer and backing buffer in addition to a shadow buffer, it's necessary to open code drm_fb_helper_fbdev_setup() to properly handle the error path. Error cleanup is removed from .fb_probe and is handled by one function for all paths. Fixes: 9060d7f4 ("drm/fb-helper: Finish the generic fbdev emulation") Reported-by:
