2007-02-13Bugzilla Bug #9457Thomas Hellstrom
Add refcounting of user waiters to the DRM hardware lock, so that we can use the DRM_LOCK_CONT flag more conservatively. Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context, when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager. It also resolves the AIGLX startup deadlock for the sis and the via drivers. i810, i830 still require that the hardware lock is really taken so the deadlock remains for those two. I'm not sure about ffb. Anyone familiar with that code?

-Remove out of memory error message. -Move sman cleanup from final_context to lastclose. -Add the P4VM800PRO (?) PCI ID.

2005-08-15Port the VIA DRM to FreeBSD. Original patch by Jake, with some cleanup byEric Anholt
me to match other drivers and avoid ifdeffing. The linux via_drv.c will be moved from shared-core to linux-core soon by repocopy. Submitted by: Jake Burkholder <jake@FreeBSD.org> Tested by: unichrome

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)
2005-08-04Split the control of master vs root priv. Everything is still marked asJon Smirl
needing root.
2005-07-03Add sysfs attribute dri_library_name on Linux. code in share-core/via_drv.cJon Smirl
is ok to be shared, it will be passive on BSD.
2005-03-28Via updates:Thomas Hellstrom
New PCI command parser. Moved from via_dma.c to via_verifier.c so functions with similar functionality are close to eachother. Moved video related functions to via_video.c, which might be extended in the future, as new video functionality is added. New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL, but with support for multiple device IRQ sources and functionality. Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and PCI parser. Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ IOCTL. Bumped minor. New version 2.6.0.
2005-02-03Via driver: Add missing drm_poll function to via driver in core.Thomas Hellstrom
2005-01-05VIA update:Thomas Hellstrom
Release video futexes when context is destroyed (This was previously done by the X server). Added New Unichrome Pro VIDEO DMA commands to the verifier. Added Quiescent heavyweight lock mode.
2004-12-13VIA drm updates:Thomas Hellstrom
1. Improved security check of AGP texture adresses. 2. Hopefully last fix of ring-buffer jump oddities. 3. Added ioctl to check available space and command regulator lag in ring-buffer. This is needed for 3D application responsiveness.
2004-12-03Added 3D functionality to the via command verifier. Modified the viaThomas Hellstrom
ring-buffer code somewhat to workaround hardware problems. Bumped via minor version number.

2004-10-10Rename fn_tbl to driver. Core driver now uses pci_driver name whichJon Smirl
reflects the personality name.

2004-10-08Changed unsigned to uint32_t in some ioctl parameters. Introduced firstThomas Hellstrom
rudimentary command verifier for dma buffers. Changed the decoder futex ioctl parameters. Bumped the via major version number.
2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.

2004-08-24This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:Erdi Chen
DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH The first ioctl sets up an area in AGP memory that will be used as the ring buffer. The second ioctl copies a command buffer from user space memory to the ring buffer. The third ioctl waits for engine idle until it returns. The motivation for this patch is to avoid the wait for engine idle call before each buffer flush in the current DRI driver. With this patch, the DRI driver can continue to flush its buffer as long as there is free space in the ring buffer. This patch adds an additional copy operation on the command buffer. This buffer copying is necessary to support multiple DRI clients rendering simultaneously. Otherwise, more CPU time will be spent in the busy loop waiting for engine idle between DRI context switch. Even in the single client case, the tradeoff is reasonable in comparision to the kernel call to check for free buffer space for the client to render directly to the ring buffer.

2004-04-121. Added a PCI ID.Thomas Hellstrom
2. Big change to the XvMC part of the SAREA. OpenGL clients will not suffer from this, and via XvMC is still alpha. Needed to make future additions to XvMC (More decoders and overlays) possible. 3. Bumped version number to 1.3.0.
