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. Submitted by: Tonnerre Lombard (partially) Tested on: FreeBSD: Rage128 AGP/PCI Linux: Savage4 AGP/PCI
2005-02-05- Implement drm_initmap, and extend it with the resource number to helpEric Anholt
FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff doesn't need to be in shared code. - Fix mach64 build by using __DECONST to work around passing a const pointer to useracc, which is unfortunately not marked const. - Get rid of a lot of maplist code by not having dev->maplist be a pointer, and by sticking the link entries directly in drm_local_map_t rather than having a separate structure for the linked list. - Factor out map uninit and removal into its own routine, rather than duplicating in both drm_takedown() and drm_rmmap(). - Hook up more driver functions, and correct FreeBSD-specific bits of radeon_cp.c, making radeon work. - Baby steps towards using bus_space as we should.
2005-01-16The patch makes drmAddBufs/drmMapBufs can handle buffers in video memoryDave Airlie
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory. From: austinyuan@viatech.com.cn (fd.o bug 1668) Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-01-01Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It usesFelix Kuehling
drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far.

2004-10-12Breakout heads into their own data structures.Jon Smirl
2004-10-10Rename fn_tbl to driver. Core driver now uses pci_driver name whichJon Smirl
reflects the personality name.
2004-10-06Revert back to drm_order() instead of using kernel get_order(). TheJon Smirl
functions are not identical.
2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
2004-09-30Move things around to reduce public symbols and even out files. Switch toJon Smirl
get_order from drm_order.
2004-09-27First check in for DRM that splits core from personality modulesJon Smirl
2004-09-21Make DRM permanent maps match broken X behavior. X is mapping regions thatJon Smirl
are both smaller and larger than what the hardware supports. If DRM tries to fix these requests X will fail.

2003-12-16Don't ioremap the framebuffer area. The ioremapped area wasn't used byEric Anholt
anything, and took up valuable KVA. While I'm in the area, clean up BSD MTRR stuff some more. Suggested by: jonsmirl
2003-11-06Return EBUSY when attempting to addmap a DRM_SHM area with a lock in it ifEric Anholt
dev->lock.hw_lock is already set. This fixes the case of two X Servers running on the same head on different VTs with interface 1.1, by making the 2nd head fail to inizialize like before.

2003-06-03Split declarations/definitions in drm_scatter.h into drm_sg.h/drm_sg_tmp.hJose Fonseca
respectively. Splited the work out of the ioctls and renamed (with the _ioctl prefix). Added some more documentation. Did the same for drm_sgpsupport.h.

be ported, rolled back r128 and i810 version bumps so 4.1.0 works with cvs kernel modules, added Config.in and updated Makefile.kernel, incorporated lots of drm fixes inspired by patches sent by Redhat, made DRM(realloc) usage check for NULL allocations, restructure driver init routines to export dev_priv only when initialized and to check for all error conditions.
2001-07-20Merge checker fixes from Alan Cox made to the drm in the ac kernel tree.Jeff Hartmann
These aren't really security problems, but Alan has made some arguments that have convinced me that the code should be fixed anyway.
