10b06bc8b3 fix buffer size in descriptor for DMA test. 2002-05-01 00:14:07 +00:00
Leif Delgass
265b19947c Enable/disable DMA based on result of gui-mastering test. MMIO mode can 
still be forced at compile time by setting MACH64_USE_DMA to 0.
DMA test now uses already allocated pci pool memory for descriptor table
    and allocates a temporary dma buffer from the pool. This should
    probabaly be changed to use one of our mapped vertex/dma buffers.
Also, return error code if _dispatch_vertex causes a lockup, either with
    DMA (wait for idle fails) or MMIO (wait for fifo times out).

dd8f31bcef Disable code that was causing kernel oops. I haven't yet determined why the 
oops happens.

45a5c02888 use virt_to_bus instead of virt_to_phys to get DMA buffer address, which 
should work on non-x86 architecures.

40a9e22bf9 Initial hacked-up code for synchronous DMA of vertex buffers (disabled but 
functional for both PCI and AGP). 16 KB descriptor table is created by
    the drm and the handles stored in the device private structure.
Finish setup of AGP -- AGP registers are now initialized.
Fix up MMIO for PCI.

95dba10bc0 Slighty more optimized DMA emulation C code. Support for waiting for 
checking empty FIFO - but disabled for now.

31a6440465 Implement streamlined vertex buffer by setting up multiple sequential 
register writes.
Register addresses in command/vertex buffer now specified by memory-mapped
    address, which is needed for real DMA.
Fix multi-reg write increment in pseudo-DMA flush (byte address needs +4
    incr.).
Restore DMAGETPTR grouping of state register writes.

e5b7dc8c19 Fixed another discrepancy in mach64_drm.h (this one harmless because is 
wasn't being used). Use of the DMAGETPTR / DMAADVANCE for which
    conditional as they aren't executed in block. Update of
    mach64_print_dirty.

bd00770298 Add agp texture region info to DRM. Also, use DMA* macros for DRM 
emit_state functions. This ensures a wait_for_fifo for the MMIO writes.

f080c751f3 Fix a discrepancy in the definition of the upload flags. This still doesn't 
fix the problem that since the last update UT and some example aren't
    showing textures anymore, but other programs do...

7aea29f4bc Preliminary changes required for AGP textures. AGP texture area is now 
mapped in the DDX driver and Mesa client. DRI and Mesa screen
    structures updated to add agp texture region data. The AGP card heap is
    not setup in the Mesa driver screen init yet, so about all this does
    right now is print AGP mode info in the renderer string and the texture
    region should show up in the X log and /proc/dri

c0622174af Code restructuring to be more similar to the existing drivers. 
Implementation of several functions to support the handling of DMA
    buffers. The DMA emulation code is disabled because it segfaults when
    trying to read the DMA buffer.

0873cfb116 Make sure we wait for enough FIFO entries (needed to add 2 to account for 
scissors being added in a couple places).

43fb03f135 Fixes for viewport calculation, scissors, and cliprects. Added drawX,drawY 
to the context struct to hold origin of drawable in draw buffer. The
    viewport is adjusted using these fields.
Enabled scissor test, drm now uses scissor values from the sarea context.
    Also enabled color masking, drm uses mask from sarea context
    (untested).
The viewport calcs seem to be working, but cliprects still have problems
    for single buffer contexts and overlapping GL windows. Needs more
    testing and debugging. I'm committing now so we can continue with
    testing.
