drm: reorganise drm tree to be more future proof. With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>

drm: replace drawable ioctl by noops The information supplied by userspace through these ioctls is only accessible by dev->drw_idr. But there's no in-tree user of that. Also userspace does not really care about return values of these ioctls, either. Only hw/xfree86/dri/dri.c from the xserver actually checks the return from adddraw and keeps on trying to create a kernel drawable every time somebody creates a dri drawable. But since that's now a noop, who cares. Therefore it's safe to replace these three ioctls with noops and rip out the implementation.

drm/bridge: make bridge registration independent of drm flow Currently, third party bridge drivers(ptn3460) are dependent on the corresponding encoder driver init, since bridge driver needs a drm_device pointer to finish drm initializations. The encoder driver passes the drm_device pointer to the bridge driver. Because of this dependency, third party drivers like ptn3460 doesn't adhere to the driver model. In this patch, we reframe the bridge registration framework so that bridge initialization is split into 2 steps, and bridge registration happens independent of drm flow: --Step 1: gather all the bridge settings independent of drm and add the bridge onto a global list of bridges. --Step 2: when the encoder driver is probed, call drm_bridge_attach for the corresponding bridge so that the bridge receives drm_device pointer and continues with connector and other drm initializations. The old set of bridge helpers are removed, and a set of new helpers are added to accomplish the 2 step initialization. The bridge devices register themselves onto global list of bridges when they get probed by calling "drm_bridge_add". The parent encoder driver waits till the bridge is available in the lookup table(by calling "of_drm_find_bridge") and then continues with its initialization. The encoder driver should also call "drm_bridge_attach" to pass on the drm_device to the bridge object. drm_bridge_attach inturn calls "bridge->funcs->attach" so that bridge can continue with drm related initializations.

drm: Add panel support 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.

drm: Add atomic/plane helpers This is the first cut of atomic helper code. As-is it's only useful to implement a pure atomic interface for plane updates. Later patches will integrate this with the crtc helpers so that full atomic updates are possible. We also need a pile of helpers to aid drivers in transitioning from the legacy world to the shiny new atomic age. Finally we need helpers to implement legacy ioctls on top of the atomic interface. The design of the overall helpers<->driver interaction is fairly simple, but has an unfortunate large interface: - We have ->atomic_check callbacks for crtcs and planes. The idea is that connectors don't need any checking, and if they do they can adjust the relevant crtc driver-private state. So no connector hooks should be needed. Also the crtc helpers integration will do the ->best_encoder checks, so no need for that. - Framebuffer pinning needs to be done before we can commit to the hw state. This is especially important for async updates where we must pin all buffers before returning to userspace, so that really only hw failures can happen in the asynchronous worker. Hence we add ->prepare_fb and ->cleanup_fb hooks for this resources management. - The actual atomic plane commit can't fail (except hw woes), so has void return type. It has three stages: 1. Prepare all affected crtcs with crtc->atomic_begin. Drivers can use this to unset the GO bit or similar latches to prevent plane updates. 2. Update plane state by looping over all changed planes and calling plane->atomic_update. Presuming the hardware is sane and has GO bits drivers can simply bash the state into the hardware in this function. Other drivers might use this to precompute hw state for the final step. 3. Finally latch the update for the next vblank with crtc->atomic_flush. Note that this function doesn't need to wait for the vblank to happen even for the synchronous case. v2: Clear drm_<obj>_state->state to NULL when swapping in state. v3: Add TODO that we don't short-circuit plane updates for now. Likely no one will care. v4: Squash in a bit of polish that somehow landed in the wrong (later) patche. v5: Integrate atomic functions into the drm docbook and fixup the kerneldoc. v6: Fixup fixup patch squashing fumble. v7: Don't touch the legacy plane state plane->fb and plane->crtc. This is only used by the legacy ioctl code in the drm core, and that code already takes care of updating the pointers in all relevant cases. This is in stark contrast to connector->encoder->crtc links on the modeset side, which we still need to set since the core doesn't touch them. Also some more kerneldoc polish. v8: Drop outdated comment. v9: Handle the state->state pointer correctly: Only clearing the ->state pointer when assigning the state to the kms object isn't good enough. We also need to re-link the swapped out state into the drm_atomic_state structure. v10: Shuffle the misplaced docbook template hunk around that Sean spotted.

drm: allow loading an EDID as firmware to override broken monitor Broken monitors and/or broken graphic boards may send erroneous or no EDID data. This also applies to broken KVM devices that are unable to correctly forward the EDID data of the connected monitor but invent their own fantasy data. This patch allows to specify an EDID data set to be used instead of probing the monitor for it. It contains built-in data sets of frequently used screen resolutions. In addition, a particular EDID data set may be provided in the /lib/firmware directory and loaded via the firmware interface. The name is passed to the kernel as module parameter of the drm_kms_helper module either when loaded options drm_kms_helper edid_firmware=edid/1280x1024.bin or as kernel commandline parameter drm_kms_helper.edid_firmware=edid/1280x1024.bin It is also possible to restrict the usage of a specified EDID data set to a particular connector. This is done by prepending the name of the connector to the name of the EDID data set using the syntax edid_firmware=[<connector>:]<edid> such as, for example, edid_firmware=DVI-I-1:edid/1920x1080.bin in which case no other connector will be affected. The built-in data sets are Resolution Name -------------------------------- 1024x768 edid/1024x768.bin 1280x1024 edid/1280x1024.bin 1680x1050 edid/1680x1050.bin 1920x1080 edid/1920x1080.bin They are ignored, if a file with the same name is available in the /lib/firmware directory. The built-in EDID data sets are based on standard timings that may not apply to a particular monitor and even crash it. Ideally, EDID data of the connected monitor should be used. They may be obtained through the drm/cardX/cardX-<connector>/edid entry in the /sys/devices PCI directory of a correctly working graphics adapter. It is even possible to specify the name of an EDID data set on-the-fly via the /sys/module interface, e.g. echo edid/myedid.bin >/sys/module/drm_kms_helper/parameters/edid_firmware The new screen mode is considered when the related kernel function is called for the first time after the change. Such calls are made when the X server is started or when the display settings dialog is opened in an already running X server.

drm: Add top level Kconfig option for DRM fbdev emulation 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.

It also works along the same lines as the AST server driver wrt memory management. There is no userspace driver planned, xf86-video-modesetting should be used. It also appears these GPUs have no ARGB hw cursors. v2: add missing tagfifo reset + G200 SE memory bw setup pieces. Signed-off-by: Dave Airlie <airlied@redhat.com>

This driver only supports the emulated GPU and doesn't attempt to bind to any real cirrus GPUs. This driver is intended to be used with xf86-video-modesetting in userspace. It requires at least version 0.3.0 This follow the same design as ast and mgag200, and is based on work done by Matthew Garrett previously.

DRM: add DRM Driver for Samsung SoC EXYNOS4210. This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables only FIMD yet but we will add HDMI support also in the future. this patch is based on git repository below: git://people.freedesktop.org/~airlied/linux.git branch name: drm-next commit-id: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 you can refer to our working repository below: http://git.infradead.org/users/kmpark/linux-2.6-samsung branch name: samsung-drm We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c based on Linux framebuffer) but couldn't so because lowlevel codes of s3c-fb.c are included internally and so FIMD module of this driver has its own lowlevel codes. We used GEM framework for buffer management and DMA APIs(dma_alloc_*) for buffer allocation so we can allocate physically continuous memory for DMA through it and also we could use CMA later if CMA is applied to mainline. Refer to this link for CMA(Continuous Memory Allocator): http://lkml.org/lkml/2011/7/20/45 this driver supports only physically continuous memory(non-iommu).

DRM: code clean and add exception codes. Changelog v3: DRM: Support multiple irq. FIMD and HDMI have their own irq handler but DRM Framework can regiter only one irq handler this patch supports mutiple irq for Samsung SoC. DRM: Consider modularization. each DRM, FIMD could be built as a module. DRM: Have indenpendent crtc object. crtc isn't specific to SoC Platform so this patch gets a crtc to be used as common object. created crtc could be attached to any encoder object. DRM: code clean and add exception codes. Changelog v4: DRM: remove is_defult from samsung_fb. is_default isn't used for default framebuffer. DRM: code refactoring to fimd module. this patch is be considered with multiple display objects and would use its own request_irq() to register a irq handler instead of drm framework's one. DRM: remove find_samsung_drm_gem_object() DRM: move kernel private data structures and definitions to driver folder. samsung_drm.h would contain only public information for userspace ioctl interface. DRM: code refactoring to gem modules. buffer module isn't dependent of gem module anymore. DRM: fixed security issue.

drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2) This is the initial driver for the Aspeed Technologies chips found in servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It doesn't support the AST11xx due to lack of hw to test it on, and them requiring different codepaths. This driver is intended to be used with xf86-video-modesetting in userspace. This driver has a slightly different design than other KMS drivers, but future server chips will probably share similiar setup. As these GPUs commonly have low video RAM, it doesn't make sense to put the kms console in VRAM always. This driver places the kms console into system RAM, and does dirty updates to a copy in video RAM. When userspace sets a new scanout buffer, it forcefully evicts the video RAM console, and X can create a framebuffer that can use all of of video RAM. This driver uses TTM but in a very simple fashion to control the eviction to system RAM of the console, and multiple servers. v2: add s/r support, fix Kconfig.

drm: add new QXL driver. (v1.4) QXL is a paravirtual graphics device used by the Spice virtual desktop interface. The drivers uses GEM and TTM to manage memory, the qxl hw fencing however is quite different than normal TTM expects, we have to keep track of a number of non-linear fence ids per bo that we need to have released by the hardware. The releases are freed from a workqueue that wakes up and processes the release ring. releases are suballocated from a BO, there are 3 release categories, drawables, surfaces and cursor cmds. The hw also has 3 rings for commands, cursor and release handling. The hardware also have a surface id tracking mechnaism and the driver encapsulates it completely inside the kernel, userspace never sees the actual hw surface ids. This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice.

drm/msm: basic KMS driver for snapdragon The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing..

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.
