* drm: Pass 'name' to drm_universal_plane_init()Ville Syrjälä2015-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Done with coccinelle for the most part. It choked on msm/mdp/mdp5/mdp5_plane.c like so: "BAD:!!!!! enum drm_plane_type type;" No idea how to deal with that, so I just fixed that up by hand. Also it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards. I didn't convert drm_plane_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ typedef uint32_t; identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5, E6, E7; @@ drm_universal_plane_init(E1, E2, E3, E4, E5, E6, E7 + ,NULL ) v2: Split crtc and plane changes apart Pass NUL for no-name instead of "" Leave drm_plane_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670795-2853-1-git-send-email-ville.syrjala@linux.intel.com

* drm/vc4: Make sure that planes aren't scaled.Eric Anholt2015-11-171-0/+10
| | | | | | | We would scan out the memory around them if an upscale was attempted, and would just scan out incorrectly for downscaling. Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | vc4_plane_init() returns an ERR_PTR on error, it doesn't return NULL. This was obviously intended because the next lines call PTR_ERR(primary_plane) already.

| | | | | | | | | | | | | | | | | | | drm-next 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.

* drm/vc4: Add KMS support for Raspberry Pi.Eric Anholt2015-10-2112-0/+2917
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.
