2003-11-04Memory layout transition:Michel Daenzer
the 2D driver initializes MC_FB_LOCATION and related registers sanely the DRM deduces the layout from these registers clients use the new SETPARAM ioctl to tell the DRM where they think the framebuffer is located in the card's address space the DRM uses all this information to check client state and fix it up if necessary This is a prerequisite for things like direct rendering with IGP chips and video capturing.
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.
2003-10-03Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have sideEric Anholt
effects, so make them look like functions (add parenthesis).
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.
2003-04-25Merge from FreeBSD-current.Eric Anholt
2003-04-24Move one definition to drm_drv.h and remove the rest of drm_init.h whichEric Anholt
was all unused.
2003-04-24Make DRM(read) and DRM(poll) stubs and remove DRM(write) andEric Anholt
DRM(write_string). This is the first part of removing much of the support code for gamma from the BSD DRM, since it appears that no new drivers are using it and nobody has ever shown interest in gamma on BSD.
2003-03-11Merge back from FreeBSD-current, adding FreeBSD ID tags to aid futureEric Anholt
merging. Also includes an update to radeon PCI IDs.
