Felix Kuehling a396617dbc Command DMA optimizations:
- don't waste DMA memory when small command buffers are flushed
- minimized padding with noops
- slightly simplified faked DMA flushing

Felix Kuehling 95fa851769 Tracked down random lockups related to command DMA that occurred in Quake3
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.

Felix Kuehling 15995234b4 Added support for command DMA on Savage4-based hardware. Unfortunately
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.

Felix Kuehling bc54ede0a8 Use wrap counter to extend 16-bit hardware event tags to 32-bit logical
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.

Eric Anholt 080a547d4d - Implement drm_initmap, and extend it with the resource number to help
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.

Felix Kuehling ffc51f1f32 Setup MTRRs for frame buffer and aperture manually on Savage3D and
Savage4-based cards. Automatic setup in drm_initmap doesn't work due to
    the weird alignment and size of the aperture.

Felix Kuehling 17d893f567 Only try to find the agp_buffer_map if dma_type is AGP. This is all that's
needed on the DRM side to support PCI Savages. Bumped patch level and
    driver date.

Felix Kuehling e7ba83bd6f Fixed off-by-one error in savage_bci_wait_fifo_shadow. 2005-01-08 23:28:27 +00:00
Felix Kuehling ae1bc4a6da 3D scissor regs are now managed by the DRM to iterate over clip rects
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

Felix Kuehling 04842e8bcf Completeley rewritten Savage DRM which can be considered secure (modulo
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.
