The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures. This also means that XFree86 4.2.0 support for i810 DRM
is lost.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM. There is a 1:1 mapping, so this
should be a noop. This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.
This was used to make all ioctl handlers return -errno on linux and errno on
*BSD. Instead, just return -errno in shared code, and flip sign on return from
shared code to *BSD code.
single DRM_COPY_FROM_USER rather than DRM_VERIFYAREA_READ followed by
tons of DRM_COPY_FROM_USER_UNCHECKED. I don't like the look of the
temporary space allocation, but I like the simplification in the rest
of the file. Tested with glxgears, tuxracer, and q3 on a savage4.
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.
Implemented SAVAGE_CMD_DMA_IDX and SAVAGE_CMD_VB_IDX for ELTs support in
the _savage_render_stage of the 3D driver
Bumped minor version and driver date
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
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.
