2015-10-21drm/vc4: Add KMS support for Raspberry Pi.Eric Anholt14-0/+2920
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.

2015-10-21drm/vc4: Add devicetree bindings for VC4.Eric Anholt1-0/+65
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: Eric Anholt <[email protected]>

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.

2015-10-19drm/gem: Use kref_get_unless_zero for the weak mmap referencesDaniel Vetter3-56/+46
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.
