2009-09-07drm/kms: Add the default mode tableZhao Yakui
When we add a standard timing mode in UMS, we will first check whether it can be found in default mode table. If it can't be found, then we will use cvt/gtf to add the standard timing mode. Add the default mode table so that we can check whether the given mode can be found in the default mode table as what we have done in UMS mode. If the status of one output device is connected but there is no EDID, it will have no correct mode. In such case we can add some default modes for it. Of course we only add the modes in the default modes list that visible part is not greater than 1024x768. The default mode is autogenerated from the DMT spec. And it is copied from xserver/hw/xfree86/modes/xf86EdidModes.c. But the mode with reduced blank feature is removed.

2009-09-07drm: split crtc/fb helpers into a separate moduleDave Airlie
I really don't want to have core drm module rely on CONFIG_FB, so this is the easiest answer. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-09-02drm/kms: add explicit encoder disable function and detach harder.Dave Airlie
For shared tv-out and VGA encoders, we really need to know if the encoder is just being switched off temporarily in blanking or if we are really disabling it hard. Also we need to try harder to disconnect encoders from unused connectors so we can share more efficently. (shared encoders stuff is coming in radeon tv-out support) Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-02drm: fix drm_cache.c for arch with no support.Dave Airlie
This produces a warn on for architectures where this gets called but we don't have a cache flushing implementation suitable. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-02drm/mm: add ability to dump mm lists via debugfsDave Airlie
This adds code to the drm_mm to talk to debugfs, and adds support to radeon to add the VRAM and GTT mm lists to debugfs. I tested with spinlock debugging and it doesn't give out. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-08-31drm/kms: Parse the detailed time info in CEA-EDIDZhao Yakui
Sometimes we can obtain the EDID with multiple blocks from the display device. For example: HDMI monitor. When the CEA-EDID block is detected, we should also parse the detailed timing info from it. Otherwise we will lose some modes for the display device. The first step is check whether the CEA EDID block is found. If it exists, it will skip the CEA-data block and parse the detailed timing info. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-08-31drm/kms: move driver specific fb common code to helper functions (v2)Dave Airlie
Initially I always meant this code to be shared, but things ran away from me before I got to it. This refactors the i915 and radeon kms fbdev interaction layers out into generic helpers + driver specific pieces. It moves all the panic/sysrq enhancements to the core file, and stores a linked list of kernel fbs. This could possibly be improved to only store the fb which has fbcon on it for panics etc. radeon retains some specific codes used for a big endian workaround. changes: fix oops in v1 fix freeing path for crtc_info Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-08-31drm/r128: Add test for initialisation to all ioctls that require itBen Hutchings
Almost all r128's private ioctls require that the CCE state has already been initialised. However, most do not test that this has been done, and will proceed to dereference a null pointer. This may result in a security vulnerability, since some ioctls are unprivileged. This adds a macro for the common initialisation test and changes all ioctl implementations that require prior initialisation to use that macro. Also, r128_do_init_cce() does not test that the CCE state has not been initialised already. Repeated initialisation may lead to a crash or resource leak. This adds that test.

2009-08-31radeon: Use request_firmware()Ben Hutchings
Loosely based on a patch by Jaswinder Singh Rajput <jaswinderlinux@gmail.com>. KMS support by Dave Airlie <airlied@redhat.com>. For Radeon 100- to 500-series, firmware blobs look like: struct { __be32 datah; __be32 datal; } cp_ucode[256]; For Radeon 600-series, there are two separate firmware blobs: __be32 me_ucode[PM4_UCODE_SIZE * 3]; __be32 pfp_ucode[PFP_UCODE_SIZE]; For Radeon 700-series, likewise: __be32 me_ucode[R700_PM4_UCODE_SIZE]; __be32 pfp_ucode[R700_PFP_UCODE_SIZE]; Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-08-19ttm: Make parts of a struct ttm_bo_device global.Thomas Hellstrom

2009-08-19drm/ttm: optimize bo_kmap_type valuesPekka Paalanen
A micro-optimization on the function ttm_kmap_obj_virtual(). By defining the values of enum ttm_bo_kmap_obj::bo_kmap_type to have a bit indicating iomem, size of the function ttm_kmap_obj_virtual() will be reduced by 16 bytes on x86_64 (gcc 4.1.2). ttm_kmap_obj_virtual() may be heavily used, when buffer objects are accessed via wrappers, that work for both kinds of memory addresses: iomem cookies and kernel virtual.

2009-08-19drm: clarify scaling property namesJesse Barnes
Now that we're using the scaling property in the Intel driver I noticed that the names were a bit confusing. I've corrected them according to our discussion on IRC and the mailing list, though I've left out potential new additions for a new scaling property with an integer (or two) for the scaling factor. None of the drivers implement that today, but if someone wants to do it, I think it could be done with the addition of a single new type and a new property to describe the scaling factor in the X and Y directions.
