staging: drm/omap: move where DMM driver is registered

2012-04-10T16:19:29+00:00

Not sure what triggered the change in behavior, but seems to result in recursively acquiring a mutex and hanging on boot. But omap_drm_init() seems a much more sane place to register the driver for the DMM sub-device. Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: use current time for page-flip event

2012-03-13T22:44:44+00:00

Because we don't have vblank hooked up via drm_irq (which is a bit awkward due to separation between omapdss (which knows the irq #) and omapdrm, for now use gettimeofday to have a semi-sane timestamp in the page-flip event. Otherwise apps like weston drm compositor, which use the timestamp in it's animations, get highly confused. Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: send page-flip event after endwin

2012-03-13T22:44:44+00:00

The endwin irq indicates that DSS has finished scanning out a buffer. Use this to trigger page-flip event to userspace, so this happens only *after* the previous buffer is finished. Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: avoid multiple planes having same z-order

2012-03-13T22:44:44+00:00

Multiple video pipes on same output with same z-order is an undefined behavior. Set a unique z-order value based on overlay number/id. Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: mmap of tiled buffers with stride >4kb

2012-03-07T21:38:08+00:00

Deal with the case of buffers with virtual stride larger than one page in fault_2d(). Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: Get DMM resources from hwmod

2012-03-07T21:38:08+00:00

This patch splits the DMM off into a separate sub-device, in order to utilize the platform device information that was created as part of the OMAP hwmod entry for the DMM. The driver probe function queries the iomem resource and IRQ using standard platform_get functions. The OMAP DRM driver now calls the platform_driver_register() function for the subordinate DMM driver inside its probe function. This guarantees the required order for the DMM and ensures the DMM resources are available for use by the DRM driver.

staging: drm/omap: Validate debugfs device

2012-03-07T21:38:07+00:00

Added check for valid device information before dumping debugfs information. Signed-off-by: Andy Gross Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: Disable DMM debugfs for OMAP3

2012-03-07T21:38:07+00:00

OMAP3 does not contain a DMM/Tiler block. As such, we should not be exposing any DMM debugfs entries on OMAP3 platforms. Added inline helper function to verify existence of DMM. Signed-off-by: Andy Gross Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: debugfs for object and fb tracking

2012-03-07T21:38:07+00:00

Add some additional debugfs file to aid in tracking buffer usage. Signed-off-by: Rob Clark Signed-off-by: Greg Kroah-Hartman

staging: drm/omap: defer unpin until scanout completes

2012-03-07T21:38:07+00:00

When flipping, defer unpinning until scanout completes, as indicated by the appropriate END_WIN irq. This also re-organizes things a bit, in replacing omap_fb_{pin,unpin} with omap_fb_replace(), to make it easier to add support for scanout synchronized DMM refill mode (flipping by just reprogramming DMM synchronized with DSS scanout).
