drm: integer overflow in drm_mode_dirtyfb_ioctl()

2012-08-17T19:34:59+00:00

commit a5cd335165e31db9dbab636fd29895d41da55dd2 upstream. There is a potential integer overflow in drm_mode_dirtyfb_ioctl() if userspace passes in a large num_clips. The call to kmalloc would allocate a small buffer, and the call to fb->funcs->dirty may result in a memory corruption.

drm: Add eDP connector type

2010-01-08T03:04:04+00:00

Add a new connector type for eDP (embedded displayport) eDP is more or less the same as DP but there are some cases when you might want to handle it separately. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie

drm: Add dirty ioctl and property

2009-12-03T23:25:47+00:00

This commit adds a ioctl and property to allow userspace to notify the kernel that a framebuffer has changed. Instead of snooping the command stream this allows finer grained tracking of which areas have changed. The primary user for this functionality is virtual hardware like the vmware svga device, but also Xen hardware likes to be notify. There is also real hardware like DisplayLink and DisplayPort that might take advantage of this ioctl. Signed-off-by: Jakob Bornecrantz Signed-off-by: Dave Airlie

drm/kms: add page flipping ioctl

2009-11-18T00:05:47+00:00

This adds a page flipping ioctl to the KMS API. The ioctl takes an fb ID and a ctrc ID and flips the crtc to the given fb at the next vblank. The ioctl returns immediately but the flip doesn't happen until after any rendering that's currently queued up against the new framebuffer is done. After submitting a page flip, any execbuffer involving the old front buffer will block until the flip is completed. Optionally, a vblank event can be generated when the swap eventually happens.

drm: clarify scaling property names

2009-08-19T06:06:40+00:00

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.

drm: Define DRM_MODE_CONNECTOR_TV

2009-08-04T04:10:56+00:00

The existing TV connector types are often unsuitable either because there is no way to probe them until they're actually plugged in or because they can change during run time (e.g. 7-pin DIN connectors that behave as S-Video, Component, Composite or SCART depending on the adaptor plugged in).

make drm headers use strict integer types

2009-03-26T17:14:18+00:00

The drm headers are traditionally shared with BSD and could not use the strict linux integer types. This is over now, so we can use our own types now. Cc: David Airlie Signed-off-by: Arnd Bergmann Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar
