| | | | | | | | | | | | | | | | | | | | Both radeon and nouveau can re-use this code so move it up a level so they can. However the hw interfaces for aux ch are different enough that the code to translate from mode, address, bytes to actual hw interfaces isn't generic, so move that code into the Intel driver.

| * drm: Add dirty ioctl and propertyJakob Bornecrantz2009-12-042-0/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * drm: Add support for drm master_[set|drop] callbacks.Thomas Hellstrom2009-12-032-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vmwgfx driver has a per master rw lock around TTM, to guarantee mutual exclusion when needed. This is typically when all evictable buffers are evicted due to 1) vt switch 2) master switch 3) suspend / resume. In the multi-master case, on master switch the new master takes the previously active master lock in write mode, and then evicts all buffers. Any clients to previous masters will then block on that lock when trying to validate a buffer. fbdev also acts as a virtual master wrt this.

| | | | | | | | | | | | | | | | | | Without an allocated colormap, FBIOGETCMAP fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the framebuffer driver does not publish detailed timing information for the current video mode, the correct value for the pixclock field is zero, not -1. Since pixclock is actually unsigned, the value -1 would be interpreted as 4294967295 picoseconds (i.e., about 4 milliseconds) by register_framebuffer() and userspace programs. This patch allows X.org's fbdev driver to work. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

| * drm/kms: add page flipping ioctlKristian Høgsberg2009-11-182-0/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm to return immediately and notify userspace when the specified vblank sequence happens by sending an event back on the drm fd. The event mechanism works with the other flags supported by the ioctls, specifically, the vblank sequence can be specified relatively or absolutely, and works for primary and seconday crtc. The signal field of the vblank request is used to provide user data, which will be sent back to user space in the vblank event.
