mesa-drm/linux-core/Makefile
Erdi Chen 25e319c1ef This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver: 
DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH
The first ioctl sets up an area in AGP memory that will be used as the ring
    buffer. The second ioctl copies a command buffer from user space memory
    to the ring buffer. The third ioctl waits for engine idle until it
    returns.
The motivation for this patch is to avoid the wait for engine idle call
    before each buffer flush in the current DRI driver. With this patch,
    the DRI driver can continue to flush its buffer as long as there is
    free space in the ring buffer.
This patch adds an additional copy operation on the command buffer. This
    buffer copying is necessary to support multiple DRI clients rendering
    simultaneously. Otherwise, more CPU time will be spent in the busy loop
    waiting for engine idle between DRI context switch. Even in the single
    client case, the tradeoff is reasonable in comparision to the kernel
    call to check for free buffer space for the client to render directly
    to the ring buffer.

Raw Blame History

# Makefile -- For the Direct Rendering Manager module (drm)
#
# Based on David Woodhouse's mtd build.
#
# Modified to handle the DRM requirements and builds on a wider range of
# platforms in a flexible way by David Dawes. It's not clear, however,
# that this approach is simpler than the old one.
#
# The purpose of this Makefile is to handle setting up everything
# needed for an out-of-kernel source build. Makefile.kernel contains
# everything required for in-kernel source builds. It is included into
# this file, so none of that should be duplicated here.

#
# By default, the build is done against the running linux kernel source.
# To build against a different kernel source tree, set LINUXDIR:
#
# make LINUXDIR=/path/to/kernel/source
#
# To build only some modules, either set DRM_MODULES to the list of modules,
# or specify the modules as targets:
#
# make r128.o radeon.o
#
# or:
#
# make DRM_MODULES="r128 radeon"
