2009-03-09FreeBSD: Fix up the flags for bus_dmamem here as well.Robert Noland
2008-10-10[FreeBSD] Rework all of the memory allocationsRobert Noland
Allocate memory from different pools. This allows the OS to track memory allocations for us, much like the linux memory debugging. This will ease tracking down memory leaks since the OS can track the number of allocations from each pool and help to point us in the right direction. Also replace drm_alloc and friends with static __inline__ versions while we are here.

bus_dmamem_alloc.
2008-05-27[FreeBSD] Convert from drm_device_t to struct drm_device for consistency.Eric Anholt
2007-08-15BSD: Replace brief description in each file's first line with doxygen later on.Eric Anholt
The brief descriptions usually had the wrong filename in them.
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.
2005-04-26Convert BSD code to mostly use bus_dma, the dma abstraction for dealingEric 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.

2005-04-16Use /*- to begin license blocks in BSD code to reduce diffs against FreeBSDEric Anholt
CVS.
2004-11-07Now that the memory debug code is gone, and all 3 BSDs have M_ZERO, stopEric Anholt
using drm_alloc/drm_free in the core and instead use plain malloc/free.
2004-11-06Commit WIP of BSD conversion to core model. Compiles for r128, radeon, butEric 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 pathsEric 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.
2003-04-26Add PCI DMA memory functions and make addbufs_pci and associated code useEric 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.
