2008-06-01[FreeBSD] Declare vblank_disable_fn callout MPSAFE.Robert Noland
2008-06-01[FreeBSD] Get rid of vbl_lock and re-use irq_lock.Robert Noland
2008-06-01[FreeBSD] Call drm_vblank_cleanup during irq uninstallRobert Noland
I needed to re-arrange some functions for this. Also needed to call DRM_SPINUNINIT on the vbl_lock during cleanup.
2008-05-27[FreeBSD] Add vblank-rework support and get drivers building.Robert Noland
The i915 driver now works again.
2008-05-27[FreeBSD] Convert from drm_device_t to struct drm_device for consistency.Eric Anholt
2007-12-02bsd: Replace other occurrences of msleep with mtx_sleepRobert Noland
2007-12-02bsd: Now make secondary vblank workRobert Noland
We needed to specifically check for driver support and test the correct vbl_received value. Also pulled over support for _DRM_VBLANK_NEXTONMISS from the linux code.
2007-12-01bsd: Hook secondary vblank support.Robert Noland
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.
2007-08-13Bug #11951: Fix an errno sign inversion on pre-FreeBSD 5.vehemens
Also, annotate where signs change, to hopefully remind the reader of these issues in the future.
2007-07-20Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-20Remove DRM_ERR OS macro.Eric Anholt
This was used to make all ioctl handlers return -errno on linux and errno on *BSD. Instead, just return -errno in shared code, and flip sign on return from shared code to *BSD code.
2007-07-18Add dry-coded DRM drawable private information storage for FreeBSD.Eric Anholt
With this, all modules build again.
2007-03-24Catch up to new interrupt API, and retire FreeBSD 4.x support here.Eric Anholt
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)
2005-07-27Correct a couple of descriptions of files in comments (were justEric Anholt
copy'n'pasted). Submitted by: jkim
2005-06-06Add a few more bits of Tonnerre's NetBSD port (Still need to deal with theEric Anholt
device attachment).
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.
2004-11-07Refine the locking of the DRM. Most significant is covering the driverEric Anholt
ioctls with dev_lock, which is a major step toward being able to remove Giant. Covers some new pieces (dev->unique*) in the core, and avoids one call down into system internals with the drm lock held, which is usually bad (FreeBSD LOR #23, #27).
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.
2004-11-06Commit 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.
2004-11-06Commit 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.
2004-05-11Merge from FreeBSD-current. Mostly 64-bit cleanliness fixes, but a fewEric Anholt
driver interface changes from -current.
2003-11-06Remove unused variable.Eric Anholt
2003-11-05- Tie the DRM to a specific device: setunique no longer succeeds when givenEric Anholt
a busid that doesn't correspond to the device the DRM is attached to. This is a breaking of backwards-compatibility only for the multiple-DRI-head case with X Servers that don't use interface 1.1. - Move irq_busid to drm_irq.h and make it only return the IRQ for the current device. Retains compatibility with previous X Servers, cleans up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be changed if necessary. - Bump interface version to 1.2. This version when set signifies that the control ioctl should ignore the irq number passed in and enable the interrupt handler for the attached device. Otherwise it errors out when the passed-in irq is not equal to the device's. - Store the highest version the interface has been set to in the device. - Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves irq_uninstall being done without the lock in some cases, but it was racey anyways.
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.
2003-10-17- 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.
