2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #4.George Sapountzis
mach64_state.c: convert the DRM_MACH64_BLIT ioctl to submit a pointer to user-space memory rather than a DMA buffer index, similar to DRM_MACH64_VERTEX. This change allows the DDX to map the DMA buffers read-only and eliminate a security problem where a client can alter the contents of the DMA buffer after submission to the DRM. This change also affects the DRI/DRM interface. Performace-wise, it basically affects PCI mode where I get a ~12% speedup for some Mesa demos I tested. This is mainly due to eliminating an ioctl for allocating the DMA buffer. mach64_dma.c: move the responsibility for allocating memory for the DMA ring in PCI mode to the DDX. This change affects the DDX/DRM interface and unifies a couple of PCI/AGP code paths for ring memory in the DRM. Bump the mach64 DRM version major and date.
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #2.George Sapountzis
Factor out from mach64_dma_dispatch_vertex() the code to reclaim an unsed buffer, in preperation for using it in mach64_dma_dispatch_blit() also.
2005-11-28Assert an MIT copyright on sis_drm.h, since one was lacking and I createdEric Anholt
that particular file. Its contents have changed a good bit since the original sis code, and the original sis code didn't care much about attribution since it routinely disclaims Precision Insight/VA Linux from responsibility. Also, adjust formatting around license headers (have a comment open immediately before the "Copyright" line, not as a runon of any previous comments) for automatic processing into FreeBSD, where /*- is used to signal the beginning of license headers for automatic compilation of license lists.
2005-11-08Correct a LOR on FreeBSD by allocating a temporary buffer and doing aEric Anholt
single COPY_FROM_USER into it, rather than VERIFYAREA followed by many COPY_FROM_USER_UNCHECKEDs.
2005-09-03convert ioctl flags to use flags instead of separate intsDave Airlie
2005-08-04Split the control of master vs root priv. Everything is still marked asJon Smirl
needing root.
2004-11-06Convert more drivers for bsd-core, moving the ioctl definitions to sharedEric Anholt
code. Remove the "drv" from sisdrv, as it's unnecessary. Use the drm_pci functions in i915 instead of per-os implementations of the same. Avoid whitespace within fields in drm_pciids.txt (one of the r300 definitions), since it breaks the bsd pciids script. Tested on sis, mga, r128. i915 needs more work.
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.
