2013-06-28drm/nouveau: always select ACPI_VIDEO if ACPI is enabled.Maarten Lankhorst
Having nouveau builtin would still allow ACPI_VIDEO to be used as external module if some of the deps for acpi_video have not been met, which would result in a linking failure. Solve this by selecting all dependencies as well.

2013-04-12drm: add new QXL driver. (v1.4)Dave Airlie
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 This requires a newer version of the QXL userspace driver, so shouldn't be enabled until that has been placed into your distro of choice. Authors: Dave Airlie, Alon Levy v1.1: fixup some issues in the ioctl interface with padding v1.2: add module device table v1.3: fix nomodeset, fbcon leak, dumb bo create, release ring irq, don't try flush release ring (broken hw), fix -modesetting. v1.4: fbcon cpu usage reduction + suitable accel flags.

2013-02-19drm/tilcdc: add TI LCD Controller DRM driver (v4)Rob Clark
A simple DRM/KMS driver for the TI LCD Controller found in various smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the CMA helpers. Currently only the TFP410 DVI encoder is supported (tested with beaglebone + DVI cape). There are also various LCD displays, for which support can be added (as I get hw to test on), and an external i2c HDMI encoder found on some boards. The display controller supports a single CRTC. And the encoder+ connector are split out into sub-devices. Depending on which LCD or external encoder is actually present, the appropriate output module(s) will be loaded. v1: original v2: fix fb refcnting and few other cleanups v3: get +/- vsync/hsync from timings rather than panel-info, add option DT max-bandwidth field so driver doesn't attempt to pick a display mode with too high memory bandwidth, and other small cleanups v4: remove some unneeded stuff from panel-info struct, properly set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Tested-by: Koen Kooi <koen@dominion.thruhere.net>

This is the initial driver for emulated cirrus GPU found in qemu. 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. This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp. i.e. it sucks. Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Its based on previous work done my Matthew Garrett but remodelled to follow the same style and flow as the AST server driver. 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.

2012-05-17drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)Dave Airlie
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.

2012-03-20drm: allow loading an EDID as firmware to override broken monitorCarsten Emde
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.

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).

2011-02-07drm/i810: remove the BKLArnd Bergmann
SMP i810 systems were practically nonexistent and the configuration was not officially supported by Intel at the time when Pentium-III was common. With this change, it is still possible to build a distribution kernel that has support for SMP and includes the i810 driver without the BKL. As a precaution, check for the theoretical SMP case at run time and refuse to load the driver. We also need to disable CONFIG_PREEMPT builds for this driver.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2010-10-21BKL: introduce CONFIG_BKL.Arnd Bergmann
With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
