git://anongit.freedesktop.org/drm-intel into drm-next Ofc I promise just a few leftovers for drm-misc and somehow it's the biggest pull. But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation. Keeps the udl hack, and qxl is tested by Gerd. * tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel: (47 commits) drm: Fixup locking WARN_ON mistake around gem_object_free_unlocked drm/etnaviv: Use lockless gem BO free callback drm/imx: Use lockless gem BO free callback drm/radeon: Use lockless gem BO free callback drm/amdgpu: Use lockless gem BO free callback drm/gem: support BO freeing without dev->struct_mutex MAINTAINERS: Add myself for the new VC4 (RPi GPU) graphics driver.

2016-05-02drm/fb-helper: Add fb_deferred_io supportNoralf Trønnes
This adds deferred io support to drm_fb_helper. The fbdev framebuffer changes are flushed using the callback (struct drm_framebuffer *)->funcs->dirty() by a dedicated worker ensuring that it always runs in process context. For those wondering why we need to be able to handle atomic calling contexts: Both panic paths and cursor code and fbcon blanking can run from atomic.

2016-02-12drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.Rafael Antognolli
This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.

This patch add support for Two Dimensional Animation and Compositing Engine (2D-ACE) on the Freescale SoCs. 2D-ACE is a Freescale display controller. 2D-ACE describes the functionality of the module extremely well its name is a value that cannot be used as a token in programming languages. Instead the valid token "DCU" is used to tag the register names and function names. The Display Controller Unit (DCU) module is a system master that fetches graphics stored in internal or external memory and displays them on a TFT LCD panel. A wide range of panel sizes is supported and the timing of the interface signals is highly configurable. Graphics are read directly from memory and then blended in real-time, which allows for dynamic content creation with minimal CPU intervention. The features: (1) Full RGB888 output to TFT LCD panel. (2) Blending of each pixel using up to 4 source layers dependent on size of panel. (3) Each graphic layer can be placed with one pixel resolution in either axis. (4) Each graphic layer support RGB565 and RGB888 direct colors without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct colors with an alpha channel and YUV422 format. (5) Each graphic layer support alpha blending with 8-bit resolution. This is a simplified version, only one primary plane, one framebuffer, one crtc, one connector and one encoder for TFT LCD panel.

2015-08-06drm: Add top level Kconfig option for DRM fbdev emulationArchit Taneja
Legacy fbdev emulation support via DRM is achieved through KMS FB helpers. Most modesetting drivers enable provide fbdev emulation by default by selecting KMS FB helpers. A few provide a separate Kconfig option for the user to enable or disbale fbdev emulation. Enabling fbdev emulation is finally a distro-level decision. Having a top level Kconfig option for fbdev emulation helps by providing a uniform way to enable/disable fbdev emulation for any modesetting driver. It also lets us remove unnecessary driver specific Kconfig options that causes bloat. With a top level Kconfig in place, we can stub out the fb helper functions when not needed without breaking functionality. Having stub functions also prevents drivers to require wrapping fb helper function calls with #ifdefs. DRM_FBDEV_EMULATION defaults to y since many drivers enable fbdev emulation by default and majority of distributions expect the fbdev interface in the kernel.

2015-06-03Add virtio gpu driver.Dave Airlie
This patch adds a kms driver for the virtio gpu. The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. The pci version of the device comes in two variants: with and without vga compatibility. The former has a extra memory bar for the vga framebuffer, the later is a pure virtio device. The only concern for this driver is that in the virtio-vga case we have to kick out the firmware framebuffer. Initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later.

In cases where MMU_NOTIFIER is not available, userptr will not be available. Similar to i915, although not making an exception for CAP_SYS_ADMIN. The proposed userspace patches for userptr seem to handle the fall- back properly, so a userptr-less kernel should not be a problem.

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.

2014-11-26drm: imx: Move imx-drm driver out of stagingPhilipp Zabel
The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm.

2014-08-06drm: Perform cmdline mode parsing during connector initialisationChris Wilson
i915.ko has a custom fbdev initialisation routine that aims to preserve the current mode set by the BIOS, unless overruled by the user. The user's wishes are determined by what, if any, mode is specified on the command line (via the video= parameter). However, that command line mode is first parsed by drm_fb_helper_initial_config() which is called after i915.ko's custom initial_config() as a fallback method. So in order for us to honour it, we need to move the cmdline parser earlier. If we perform the connector cmdline parsing as soon as we initialise the connector, that cmdline mode and forced status is then available even if the fbdev helper is not compiled in or never called. We also then expose the cmdline user mode in the connector mode lists. v2: Rebase after connector->name upheaval. v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely simplifies things while at that. v4: Fix checkpatch. v5: Select FB_CMDLINE to adapt to the changed fbdev patch.

2014-06-02drm/exynos: Fix PTN3460 dependencyJean Delvare
The following configuration options combination: CONFIG_DRM_EXYNOS_DP=y CONFIG_DRM_PTN3460=m currently leads to the following linker failure: drivers/built-in.o: In function `exynos_drm_attach_lcd_bridge': .../drivers/gpu/drm/exynos/exynos_dp_core.c:1004: undefined reference to `ptn3460_init' This is because ptn3460_init can't be implemented in a module while its caller is built into the kernel. So add the proper dependency in Kconfig so that the above can't happen. I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module section, so that the user has a chance to select it before moving to the Exynos-specific section. IMHO the proper way to solve the problem would be to turn ptn3460 into a clean I2C driver, similar to the other I2C helper chip drivers. It's the only way to not sink into impossible-to-guess dependencies. Then ptn3460 could even be moved together with the other I2C helper chip drivers.

2013-12-17drm: Add panel supportThierry Reding
Add a very simple framework to register and lookup panels. Panel drivers can initialize a DRM panel and register it with the framework, allowing them to be retrieved and used by display drivers. Currently only support for DPMS and obtaining panel modes is provided. However it should be sufficient to enable a large number of panels. The framework should also be easily extensible to support more sophisticated kinds of panels such as DSI. The framework hasn't been tied into the DRM core, even though it should be easily possible to do so if that's what we want. In the current implementation, display drivers can simple make use of it to retrieve a panel, obtain its modes and control its DPMS mode. Note that this is currently only tested on systems that boot from a device tree. No glue code has been written yet for systems that use platform data, but it should be easy to add.

MIPI DSI bus allows to model DSI hosts and DSI peripherals using the Linux driver model. DSI hosts are registered by the DSI host drivers. During registration DSI peripherals will be created from the children of the DSI host's device tree node. Support for registration from board-setup code will be added later when needed. DSI hosts expose operations which can be used by DSI peripheral drivers to access associated devices.

into drm-next drm/tegra: Changes for v3.13-rc1 The biggest part of the changes is the decoupling of the host1x and DRM drivers followed by the move of Tegra DRM back to drivers/gpu/drm/tegra from whence it came. There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.
