2007-08-15BSD: Replace brief description in each file's first line with doxygen later on.Eric Anholt
The brief descriptions usually had the wrong filename in them.
2005-08-05Rename the driver hooks in the DRM to something a little moreEric Anholt
understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
2005-04-16Use /*- to begin license blocks in BSD code to reduce diffs against FreeBSDEric Anholt
CVS.
2005-02-13Fix bad copy'n'pastage of copyrights -- don't disclaim anything for VAEric Anholt
Linux or PI in my copyrights when I should be doing it for myself.
2005-02-05- Implement drm_initmap, and extend it with the resource number to helpEric Anholt
FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff doesn't need to be in shared code. - Fix mach64 build by using __DECONST to work around passing a const pointer to useracc, which is unfortunately not marked const. - Get rid of a lot of maplist code by not having dev->maplist be a pointer, and by sticking the link entries directly in drm_local_map_t rather than having a separate structure for the linked list. - Factor out map uninit and removal into its own routine, rather than duplicating in both drm_takedown() and drm_rmmap(). - Hook up more driver functions, and correct FreeBSD-specific bits of radeon_cp.c, making radeon work. - Baby steps towards using bus_space as we should.
2004-12-15Use SYSCTL_ADD_OID macro instead of calling function directly.Eric Anholt
Submitted by: reffie@FreeBSD.org
2004-11-07Now that the memory debug code is gone, and all 3 BSDs have M_ZERO, stopEric Anholt
using drm_alloc/drm_free in the core and instead use plain malloc/free.
2004-11-06Hook the debug output up to a sysctl, so you can choose to enable atEric Anholt
runtime.
2004-11-06Commit first pieces of port to OpenBSD, done by Martin Lexa (martin atEric Anholt
martinlexa dot cz). Now that we've got porting for all three major BSDs (and the fourth being very similar to FreeBSD), move the mostly-duplication drm_os_* files into drmP.h. Remove some cruft from linux heritage and from pieces of the DRM that have since been removed. Note that things are still not quite working for even FreeBSD, but these are first steps at cleanup, and just a WIP checkpoint.
2004-11-06Remove the vestiges of the memory-debug code.Eric Anholt
2004-11-06Commit WIP of BSD conversion to core model. Compiles for r128, radeon, butEric Anholt
doesn't run yet. Moves the ioctl definitions for these two drivers back to the shared code -- they aren't OS-specific.
2003-12-16Don't ioremap the framebuffer area. The ioremapped area wasn't used byEric Anholt
anything, and took up valuable KVA. While I'm in the area, clean up BSD MTRR stuff some more. Suggested by: jonsmirl
2003-10-24Don't try to use dev->dma_lock unless dma is initialized (dev->dma != NULL)Eric Anholt
in bufs_info sysctl handler. dev->dma and dev->dma_lock existence are protected by DRM_LOCK(). Fixes panic on sysctl hw.dri when the device is uninitialied (when you aren't in X).
2003-10-22Fix warning about static DRM(bufs_info) defined but not used in theEric Anholt
!__HAVE_DMA case.
2003-10-20Fix the possibility of sleeping with locks held in sysctls by copying theEric Anholt
data into temporary variables with the lock held then outputting to sysctls with the lock released. Rearranged a little extra code to aid this. Note that drm_memory_debug.h hasn't had this fix applied, but I consider that code to be just about dead anyway.
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).
2003-10-02Add an MIT-style copyright, assigned to myself, to these files. I thinkEric Anholt
I've touched enough of the code here, and there was no previous copyright. Do some drive-by style fixes while I'm here.
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.
2003-04-26Fix formatting of hw.dri sysctl.Eric Anholt
2003-04-26Missed files in the last commit: Remove memory debugging sysctl unlessEric Anholt
MEMORY_DEBUG is set.
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 DRM_DMA_HISTOGRAM and associated code.Eric Anholt
2003-03-29Remove dead vma code and remove the unused devstate struct definition.Eric Anholt
2003-03-11Merge back from FreeBSD-current, adding FreeBSD ID tags to aid futureEric Anholt
merging. Also includes an update to radeon PCI IDs.
