| | | | | | | | | | | | | This time, abandon the use of busdma and start interacting with the VM system directly. Make use of the new kmem_alloc_attr() which allows us to easily allocate non-contiguous pages to back the GART table.

* Rework how drm maps are handled.Robert Noland2010-04-2223-168/+201
| | | | | | | | | | | | | | | * On 32 bit platforms we steal the upper 4 bits of the map handle to store a unique map id. * On 64 bit platforms we steal the upper 24 bits. Resolves issues where the offsets that are handed to mmap may overlap the VRAM on some cards. Tested on: radeon, intel, mga, and via. This will break nouveau. I will spin new patches shortly.

* Make the newbus subsystem Giant free by adding the new newbus sxlock.Attilio Rao2009-08-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.
