2011-06-16drm/radeon: workaround a hw bug on some radeon chipsets with all-0 EDIDs.Dave Airlie1-0/+2
Some RS690 chipsets seem to end up with floating connectors, either a DVI connector isn't actually populated, or an add-in HDMI card is available but not installed. In this case we seem to get a NULL byte response for each byte of the i2c transaction, so we detect this case and if we see it we don't do anymore DDC transactions on this connector. I've tested this on my RS690 without the HDMI card installed and it seems to work fine. Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com>

Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds the capability to wait on vblank events for CRTCs that are greater than 1 and thus cannot be represented with primary/secondary flags in the legacy interface. It was discussed on the dri-devel list in these two threads: http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html This patch extends the interface to drm_wait_vblank ioctl so that crtc>1 can be represented. It also adds a new capability to drm_getcap ioctl so that the user space can check whether the new interface to drm_wait_vblank is supported (and fall back to the legacy interface if not) Signed-off-by: Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Acked-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Tested-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-02-23drm: mm: add api for embedding struct drm_mm_nodeDaniel Vetter1-5/+14
The old api has a two-step process: First search for a suitable free hole, then allocate from that specific hole. No user used this to do anything clever. So drop it for the embeddable variant of the drm_mm api (the old one retains this ability, for the time being). With struct drm_mm_node embedded, we cannot track allocations anymore by checking for a NULL pointer. So keep track of this and add a small helper drm_mm_node_allocated. Also add a function to move allocations between different struct drm_mm_node. v2: Implement suggestions by Chris Wilson.

2011-02-23drm: mm: track free areas implicitlyDaniel Vetter1-9/+12
The idea is to track free holes implicitly by marking the allocation immediatly preceeding a hole. To avoid an ugly corner case add a dummy head_node to struct drm_mm to track the hole that spans to complete allocation area when the memory manager is empty. To guarantee that there's always a preceeding/following node (that might be marked as hole_follows == 1), move the mm->node_list list_head to the head_node. The main allocator and fair-lru scan code actually becomes simpler. Only the debug code slightly suffers because free areas are no longer explicit. Also add drm_mm_for_each_node (which will be much more useful when struct drm_mm_node is embeddable).

2011-02-23drm/nouveau: don't munge in drm_mm internalsDaniel Vetter1-0/+5
Nouveau was checking drm_mm internals on teardown to see whether the memory manager was initialized. Hide these internals in a small inline helper function.

2011-02-22ttm: Include the 'struct dev' when using the DMA API.Konrad Rzeszutek Wilk2-2/+7
This makes the accounting when using 'debug_dma_dump_mappings()' and CONFIG_DMA_API_DEBUG=y be assigned to the correct device instead of 'fallback'. No functional change - just cosmetic. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2011-02-07drm: add usb frameworkDave Airlie2-0/+17
This adds an initial framework to plug USB graphics devices into the drm/kms subsystem. I've started writing a displaylink driver using this interface. Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-02-07drm: rework PCI/platform driver interface.Dave Airlie1-55/+51
This abstracts the pci/platform interface out a step further, we can go further but this is far enough for now to allow USB to be plugged in. The drivers now just call the init code directly for their device type. Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-02-07drm: dumb scanout create/mmap for intel/radeon (v3)Dave Airlie4-0/+52
This is just an idea that might or might not be a good idea, it basically adds two ioctls to create a dumb and map a dumb buffer suitable for scanout. The handle can be passed to the KMS ioctls to create a framebuffer. It looks to me like it would be useful in the following cases: a) in development drivers - we can always provide a shadowfb fallback. b) libkms users - we can clean up libkms a lot and avoid linking to libdrm_*. c) plymouth via libkms is a lot easier. Userspace bits would be just calls + mmaps. We could probably mark these handles somehow as not being suitable for acceleartion so as top stop people who are dumber than dumb.

2011-02-07drm: remove i830 driverArnd Bergmann2-343/+0
This driver is one of the last users of the big kernel lock, which is going away. All the hardware supported by this driver also works with the newer i915 driver, and recent X.org releases only work with that driver anyway.

0x4243 is a PCI bridge, not a GPU. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=33815 Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
