from __HAVE_DMA. This will be useful for adding vblank sync support to
sis and tdfx. Rename dma_service to irq_handler, which is more
accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
the right number of underscores. This may have been a problem in the
case that the server died without doing its DRM_IOCTL_CONTROL to
uninit.
Change some nearby memset()s to bzero()s or to calloc allocations to
take advantage of M_ZERO). Reverse some error tests to reduce high
levels of indentation. Move the sg_cleanup() call out of the maplist
loop in DRM(takedown)-- I can't see any need for it to be inside.
it. To do this we need to save the bus address along with the virtual
address in the seglist. Also fix some error handling and a few bits of
whitespace.
post-drm-filp-0-1-branch world. The filp is a void * cast from the
current pid. This is a temporary solution which maintains the status
quo until a proper solution is implemented.
What is really needed is a unique pointer per open, hopefully with a device
private area. This can be done in FreeBSD for all entry points except
mmap, but is difficult (sys/dev/streams/streams.c is an example). I
have partially completed code for this but have not had time to debug,
so this is a temporary fix.
