2005-09-03	convert ioctl flags to use flags instead of separate ints	Dave Airlie

2005-08-09	Make sure savage has 3rd ioctl parameter	Jon Smirl

2005-08-07	make some functions static in the savage drm driver	Dave Airlie

2005-08-05	Rename the driver hooks in the DRM to something a little more	Eric Anholt
	understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
2005-06-28	- Remove drm_initmap and replace its usage with drm_addmap. This reduces	Eric Anholt
	code duplication, and it also hands you the map pointer so you don't need to re-find it. - Remove the permanent maps flag. Instead, for register and framebuffer maps, we always check whether there's already a map of that type and offset around. Move the Radeon map initialization into presetup (first open) so it happens again after every takedown. - Remove the split cleanup of maps between driver takedown (last close) and cleanup (module unload). Instead, always tear down maps on takedown, and drivers can recreate them on first open. - Make MGA always use addmap, instead of allocating consistent memory in the PCI case and then faking up a map for it, which accomplished nearly the same thing, in a different order. Note that the maps are exposed to the user again: we may want to expose a flag to avoid this, but it's not a security concern, and saves us a lot of code. - Remove rmmaps in the MGA driver. Since the function is only called during takedown anyway, we can let them die a natural death. - Make removal of maps happen in one function, which is called by both drm_takedown and drm_rmmap_ioctl. Reviewed by: idr (previous revision) Tested on: mga (old/new/pci dma), radeon, savage
2005-06-21	Change initialization of savage register access to _DRM_READ_ONLY. Flags of	Jon Smirl
	zero does not mean no privs, instead it grants write access _DRM_READ_ONLY only applies to non-root users. Problem is only in CVS, initmaps are not in the kernel yet.
2005-06-04	Remove warnings about code mixed with declerations..	Dave Airlie

2005-03-13	Command DMA optimizations:	Felix Kuehling
	- don't waste DMA memory when small command buffers are flushed - minimized padding with noops - slightly simplified faked DMA flushing
2005-03-07	Tracked down random lockups related to command DMA that occurred in Quake3	Felix Kuehling
	after ~5min: buffer aging was subtly broken. Part of this may have also affected vertex DMA buffer aging and client-side texture heap aging, though with less fatal consequences. Bumped minor version and driver date.
2005-03-06	Added support for command DMA on Savage4-based hardware. Unfortunately	Felix Kuehling
	command and vertex DMA don't work at the same time. Command DMA performance is superior and works with all vertex formats. Bumped minor version and driver date.
2005-02-23	Use wrap counter to extend 16-bit hardware event tags to 32-bit logical	Felix Kuehling
	event counters in the SAVAGE_EVENT_EMIT/WAIT ioctls. This is needed for reliable client-side texture heap aging. Slightly simplified DMA buffer aging while at it. Bumped minor version and driver date.
2005-02-05	- Implement drm_initmap, and extend it with the resource number to help	Eric 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.
2005-01-15	Setup MTRRs for frame buffer and aperture manually on Savage3D and	Felix Kuehling
	Savage4-based cards. Automatic setup in drm_initmap doesn't work due to the weird alignment and size of the aperture.
2005-01-10	Only try to find the agp_buffer_map if dma_type is AGP. This is all that's	Felix Kuehling
	needed on the DRM side to support PCI Savages. Bumped patch level and driver date.
2005-01-08	Fixed off-by-one error in savage_bci_wait_fifo_shadow.	Felix Kuehling

2005-01-05	3D scissor regs are now managed by the DRM to iterate over clip rects	Felix Kuehling
	passed to the cmdbuf ioctl (try xeyes on top of glxgears ;-) Tightened the texture state check Bumped Savage DRM version to 2.1.0 so that DRI driver can (theoretically) depend on the DRM to manage the scissor registers
2005-01-01	Completeley rewritten Savage DRM which can be considered secure (modulo	Felix Kuehling
	implementation errors). Direct hardware (MMIO, BCI) access is no longer needed in the Mesa driver. Bumped version to 2.0.0. Corresponding changes to the DDX and Mesa drivers are being committed.
