Tegra uses the CMA FB helpers so framebuffers passed to the driver need to use the corresponding functions to access the underlying GEM objects. This used to work because struct tegra_framebuffer was sufficiently similar to struct drm_fb_cma but that isn't guaranteed to stay that way.

Driver implementations of the drm_crtc's .page_flip() function are required to update the crtc->fb field on success to reflect that the new framebuffer is now in use. This is important to keep reference counting on the framebuffers balanced. While at it, document this requirement to keep others from falling into the same trap. Suggested-by:

Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next The summary: . Add display mode check operaion to mixer driver - Mixer IP also can put certain restrictions on the proposed display modes and these restrictions need to be considered during mode negotiation, which happens immediately after edid parsing. . Set correct mode for range of resolutions - With this patch, the mixer driver could find the correct mode for the range of resolutions upto 1080 vertical lines. . Support extra resolution for hdmi - This patch programs the core and timing generator registers using the timing data provided in drm_display_mode without hard-coded configurations. So this patch adds additional PHY configs to allow us to support more permissible resolutions and refresh rates. . Add device tree support for g2d - This patch adds just the compatible string for exynos5250 SoC so that with device tree enabling, this driver can be probed. . And bug fixes and code cleanups. * 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: Add device tree based discovery support for G2D drm/exynos: hdmi: support extra resolutions using drm_display_mode timings drm/exynos: mixer: set correct mode for range of resolutions drm/exynos: implement display-mode-check callback in mixer driver drm/exynos: add display-mode-check operation to exynos_mixer_ops struct drm/exynos: release resources properly when fb creation is failed. drm/exynos: fix wrong pointer access at vm close. drm/exynos: Add missing braces around sizeof drm/exynos: consider exception case to fb handle creation drm/exynos: fix iommu address allocation order

The values of n, m1 and m2 needs to be subtracted by 2 before writing them to the FP register. The dot clock calculation already thinks of these values in register form so we must also specify them as such. Signed-off-by:

This patch adds the implementation of check_timing callback in the mixer driver. Based on the mixer version, correct set of restrictions will be exposed by the mixer driver. A resolution will be acceptable only if passes the criteria set by mixer and hdmi IPs. Signed-off-by:

This patch adds the display mode check operation to exynos_mixer_ops in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions on the proposed display modes. These restriction needs to be considered during mode negotiation, which happens immediately after edid parsing. Both, mixer check-mode and hdmi check-timing callbacks are called one after another and ANDed result is returned back. Signed-off-by:

This patch fixes wrong pointer access issue to filp->f_op and filp->private_data. The exynos_drm_gem_mmap_ioctl() changes filp->f_op and filp->private_data temporarily and restore them to use original ones in exynos_drm_gem_mmap_buffer() but there was no lock between the changing and the restoring so wrong pointer access to filp->f_op and filp->private_data was induced by vm close callback. So this patch uses mutex lock properly to resolve this issue. Signed-off-by:

Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next Nothing terribly exciting in here probably: - reworked thermal stuff from mupuf/I, has a chance of possibly working well enough when we get to being able to reclock.. - driver will report mmio access faults on chipsets where it's supported - will now sleep waiting on fences on nv84+ rather than polling - some cleanup of the internal fencing, looking towards sli/dmabuf sync - initial support for anx9805 dp/tmds encoder - nv50+ display fixes related to the above, and also might fix a few other issues - nicer error reporting (will log process names with channel errors) - various other random fixes * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) nouveau: ACPI support depends on X86 and X86_PLATFORM_DEVICES drm/nouveau/i2c: add support for ddc/aux, and dp link training on anx9805 drm/nv50: initial kms support for off-chip TMDS/DP encoders drm/nv50-/disp: initial supervisor support for off-chip encoders drm/nv50-/disp: initial work towards supporting external encoders drm/nv50-/kms: remove unnecessary wait-for-completion points drm/nv50-/disp: move DP link training to core and train from supervisor drm/nv50-/disp: handle supervisor tasks from workqueue drm/nouveau/i2c: create proper chipset-specific class implementations drm/nv50-/disp: 0x0000 is a valid udisp config value drm/nv50/devinit: reverse the logic for running encoder init scripts drm/nouveau/bios: store a type/mask hash in parsed dcb data drm/nouveau/i2c: extend type to 16-bits, add lookup-by-type function drm/nouveau/i2c: aux channels not necessarily on nvio drm/nouveau/i2c: fix a bit of a thinko in nv_wri2cr helper functions drm/nouveau/bios: parse external transmitter type if off-chip drm/nouveau: store i2c port pointer directly in nouveau_encoder drm/nouveau/i2c: handle i2c/aux mux outside of port lookup function drm/nv50/graph: avoid touching 400724, it doesn't exist drm/nouveau: Fix DPMS 1 on G4 Snowball, from snow white to coal black. ...

DP link training is now handled as part of the supervisor processing, and can no longer race with it. Signed-off-by: -
Ben Skeggs authored
We need to be able to do link training for PIOR-connected ANX9805 from the third supervisor handler (due to script ordering in the bios, can't have the "user" call train because some settings are overwritten from the modesetting bios scripts). This moves link training for SOR-connected DP encoders to the second supervisor interrupt, *before* we call the modesetting scripts (yes, different ordering from PIOR is necessary). This is useful since we should now be able to remove some hacks to workaround races between the supervisor and link training paths. Signed-off-by: -
