2005-08-26	- Don't try to allocate mappings of less than a PAGE_SIZE in MGA DMA code.	Eric Anholt
	- Comment out the "is this mapping/bufs in allocated AGP" bits in BSD because they break mga (which uses AGP allocation that doesn't track entries). It's not a security issue when we still have the related ioctls marked root-only. - Apply some power-of-two alignment restrictions to hopefully avoid some panicing in bad cases of drm_pci_alloc() on FreeBSD. - Add verbosity to some error handling that I found useful while debugging.
2005-04-26	Convert BSD code to mostly use bus_dma, the dma abstraction for dealing	Eric Anholt
	with IOMMUs and such. There is one usage of the forbidden vtophys() left in drm_scatter.c which will be fixed up soon. This required a KPI change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that keeps track of os-specific bits, rather than just passing around the vaddr/busaddr/size. Submitted by: Tonnerre Lombard (partially) Tested on: FreeBSD: Rage128 AGP/PCI Linux: Savage4 AGP/PCI
2005-04-16	Use /*- to begin license blocks in BSD code to reduce diffs against FreeBSD	Eric Anholt
	CVS.
2004-11-07	Now that the memory debug code is gone, and all 3 BSDs have M_ZERO, stop	Eric Anholt
	using drm_alloc/drm_free in the core and instead use plain malloc/free.
2004-11-06	Commit WIP of BSD conversion to core model. Compiles for r128, radeon, but	Eric Anholt
	doesn't run yet. Moves the ioctl definitions for these two drivers back to the shared code -- they aren't OS-specific.
2003-10-19	- SMPng lock the DRM. This is only partial -- there are a few code paths	Eric Anholt
	used by root (the X Server) which are not locked. However, it should deal with lost-IRQ issues on -current which I think people have been experiencing but I am unable to reproduce (though I understand why they would occur, because of a bug of mine). Note that most of the locking (DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't matter yet. - Remove locking on FreeBSD-stable and NetBSD. These are covered by the fact that there is no reentrancy of the kernel except by interrupts, which are locked using spldrm()/splx() instead.
2003-04-26	Add PCI DMA memory functions and make addbufs_pci and associated code use	Eric Anholt
	it. To do this we need to save the bus address along with the virtual address in the seglist. Also fix some error handling and a few bits of whitespace.
