This pull request introduces the vc4 driver, for kernel modesetting on the Raspberry Pi (bcm2835/bcm2836 architectures). It currently supports a display plane and cursor on the HDMI output. The driver doesn't do 3D, power management, or overlay planes yet. [airlied: fixup the enable/disable vblank APIs] Acked-by:

This is enough for fbcon and bringing up X using xf86-video-modesetting. It doesn't support the 3D accelerator or power management yet. v2: Drop FB_HELPER select thanks to Archit's patches. Do manual init ordering instead of using the .load hook. Structure registration more like tegra's, but still using the typical "component" code. Drop no-op hooks for atomic_begin and mode_fixup() now that they're optional. Drop sentinel in Makefile. Fix minor style nits I noticed on another reread. v3: Use the new bcm2835 clk driver to manage pixel/HSM clocks instead of having a fixed video mode. Use exynos-style component driver matching instead of devicetree nodes to list the component driver instances. Rename compatibility strings to say bcm2835, and distinguish pv0/1/2. Clean up some h/vsync code, and add in interlaced mode setup. Fix up probe/bind error paths. Use bitops.h macros for vc4_regs.h v4: Include i2c.h, allow building under COMPILE_TEST, drop msleep now that other bugs have been fixed, add timeouts to cpu_relax() loops, rename hpd-gpio to hpd-gpios.

VC4 is the GPU (display and 3D) subsystem present on the 2835 and some other Broadcom SoCs. This binding follows the model of msm, imx, sti, and others, where there is a subsystem node for the whole GPU, with nodes for the individual HW components within it. v2: Extend the commit message, fix several nits from Stephen Warren. v3: Rename the compatibility strings, clean up node names, drop the unnecessary lists of components. Use compatibility strings for choosing CRTC HVS channel numbers. Document the HDMI clock usage. v4: Whitespace fix, expand acronyms, move to display/ instead of gpu/, rename "hpd-gpio" to "hpd-gpios". Signed-off-by:

The plane reset handler frees the plane state and allocates a new default state, but when doing so attempt to free the plane state using the base plane state pointer instead of casting it to the driver-specific state object that has been allocated. Fix it by using the rcar_du_plane_atomic_destroy_state() function to destroy the plane state instead of duplicating the code. Signed-off-by:

In commit bbb1e524 Author: Rob Clark <robdclark@gmail.com> Date: Tue Aug 25 15:35:58 2015 -0400 drm/fb-helper: atomic restore_fbdev_mode().. we've forgotten to do the plane->old_fb refcount dance for pan_display_atomic, which can result in refcount leaks if the current configuration is not from fbcon. Which apparently can happen when vt-switching - fbcon does a pan first before a set_par. OCD-align function parameters while at it. v2: Actually git add the OCD.

In Linux 4.3-rc5, there is an error case in drm_dp_get_branch_device that returns without releasing mgr->lock, resulting a spew of kernel messages about a kernel work function possibly having leaked a mutex and presumably more serious adverse consequences later. This patch changes the error to "goto out" to unlock the mutex before returning. Signed-off-by:

On atomic drivers we can dig out the primary plane rotation from the plane state instead of looking at the legacy crtc->invert_dimensions flag.

Currently everyone and their dog has their own favourite spelling for vga_switcheroo. This makes it hard to grep dmesg for log entries relating to vga_switcheroo. It also makes it hard to find related source files in the tree. vga_switcheroo.c uses pr_fmt "vga_switcheroo". Use that everywhere. Signed-off-by:

Compared to wrapping the final kref_put with dev->struct_mutex this allows us to only acquire the offset manager look both in the final cleanup and in the lookup. Which has the upside that no locks leak out of the core abstractions. But it means that we need to hold a temporary reference to the object while checking mmap constraints, to make sure the object doesn't disappear. Extended the critical region would have worked too, but would result in more leaky locking. Also, this is the final bit which required dev->struct_mutex in gem core, now modern drivers can be completely struct_mutex free! This needs a new drm_vma_offset_exact_lookup_locked and makes both drm_vma_offset_exact_lookup and drm_vma_offset_lookup unused. v2: Don't leak object references in failure paths (David). v3: Add a comment from Chris explaining how the ordering works, with the slight adjustment that I dropped any mention of struct_mutex since with this patch it's now immaterial ot core gem.

In its original version, drm_framebuffer_init() returned a negative int if drm_mode_object_get() failed (f453ba04, "DRM: add mode setting support"). This was accidentally disabled by commit 4b096ac1 ("drm: revamp locking around fb creation/destruction"). Thus, drm_framebuffer_init() pretends success if drm_mode_object_get() failed. Reinstate the original behaviour. Also fix erroneous kernel-doc of drm_mode_object_get().

DRM is a lot more than a direct rendering manager nowadays, and there's also a bunch of things worth documenting for gpu driver developers outside of drivers/gpu/drm, like vgaarb, vga_switcheroo or the various hardware buses like host1x and ipu-v3. To avoid further confusion let's rename the top-level to reflect reality. And yes I'm already looking forward to when we need to replace the G in GPU with a * ;-) Inspired by a thread with Lukas since he refused to include the vga_switcheroo docs into the drm docs because it's not drm.
