2003-10-19- SMPng lock the DRM. This is only partial -- there are a few code pathsEric Anholt
used by root (the X Server) which are not locked. However, it should deal with lost-IRQ issues on -current which I think people have been experiencing but I am unable to reproduce (though I understand why they would occur, because of a bug of mine). Note that most of the locking (DRM_LOCK()/UNLOCK()) is all covered by Giant still, so it doesn't matter yet. - Remove locking on FreeBSD-stable and NetBSD. These are covered by the fact that there is no reentrancy of the kernel except by interrupts, which are locked using spldrm()/splx() instead.
2003-10-19Clean up extra zeroing of dev->dma, and use calloc to take advantage ofEric Anholt
M_ZERO.
2003-10-17- Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle themEric Anholt
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.
2003-10-03Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have sideEric Anholt
effects, so make them look like functions (add parenthesis).
2003-10-02Mostly whitespace cleanups and style(9) fixes focused on "if(" -> "if ("Eric Anholt
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.
2003-08-19- Remove $FreeBSD$ tags as they weren't too useful and merges are now beingEric Anholt
done through perforce. - Add copyright headers to drm_os_*bsd.h, still need to research the other copyright-less files better.

i830 build fix
2003-07-25Compile fixes for recent 2.5/2.6 Linux kernels. I hope this doesn't breakMichel Daenzer
the i830 driver or the BSDs. :)
2003-04-26MFL: Don't install irq handler unless the driver has been initialized.Eric Anholt
2003-04-26Add PCI DMA memory functions and make addbufs_pci and associated code useEric Anholt
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.
2003-04-25Merge from FreeBSD-current.Eric Anholt
2003-04-24Remove more gamma DMA infrastructure. Most of this code was copied straightEric Anholt
from linux, so it could be added back if some driver needed it in the future.
2003-04-24Remove more gamma DMA code. This isn't all of it, but it's a major portion.Eric Anholt
2003-04-24Remove DRM_DMA_HISTOGRAM and associated code.Eric Anholt
2003-03-29Add DRMFILE definitions and supply filp for BSD in theEric Anholt
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.
2003-03-11Merge back from FreeBSD-current, adding FreeBSD ID tags to aid futureEric Anholt
merging. Also includes an update to radeon PCI IDs.
2003-03-06Remove the vbl signal code because it's untested (and has lock issues onEric Anholt
-current).
