2008-05-20	[gem] Clean up active/inactive list handling using helper functions.	Eric Anholt
	Additionally, a boolean active field is added to indicate which list an object is on, rather than smashing last_rendering_cookie to 0 to show inactive. This will help with flush-reduction later on, and makes the code clearer.
2008-05-15	[gem] Hold dev->struct_mutex to protect structure data.	Eric Anholt

2008-05-15	[gem] Rename the GTT LRU lists to active (executing) and inactive (idle).	Eric Anholt

2008-05-15	[gem] typo fix in comment.	Eric Anholt

2008-05-12	[GEM] Update testcases for new API.	Eric Anholt

2008-05-12	[GEM] Typo (and thinking) fixes in drm-gem.txt and doxygen.	Eric Anholt

2008-05-12	[intel] Minor kludge -- wait for the ring to be nearly empty before queuing	Keith Packard
	No need to fill the ring that much; wait for it to become nearly empty before adding the execbuffer request. A better fix will involve scheduling ring insertion in the irq handler.
2008-05-12	[intel] When polling for ring space, sleep for a lot longer (10ms)	Keith Packard
	If the ring is full, the engine will surely be running for more than 10ms.
2008-05-12	[gem] Set write domain to CPU when doing pwrite.	Keith Packard
	Leave the flush call in place, which can fix domains up if necessary.
2008-05-12	[gem] Clarify use of explicit domain control. Remove Gen3 from I-cache usage.	Keith Packard

2008-05-11	[GEM] Make pread/pwrite manage memory domains. No luck with movnti though.	Keith Packard
	pread and pwrite must update the memory domains to ensure consistency with the GPU. At some point, it should be possible to avoid clflush through this path, but that isn't working for me.
2008-05-10	[intel-GEM] exec list can contain pinned, lru cannot.	Keith Packard
	The exec list contains all objects, in order of use. The lru list contains only unpinned objects ready to be evicted. This required two changes -- the first was to not migrate pinned objects from exec to lru, the second was to search for the first unpinned object in the exec list when doing eviction.
2008-05-10	Merge commit 'anholt/drm-gem' into drm-gem	Keith Packard

2008-05-10	[GEM] Add drm-gem.txt	Keith Packard
	Add some API and implementation documentation for GEM.
2008-05-10	[intel-GEM] Clean up GEM ioctl naming.	Keith Packard
	Rename 'validate_entry' to 'exec_object', then clean up some field names in structures (renaming buffer_offset to just offset, for example).
2008-05-09	GEM: Fix arguments to drm_memrange_init so we don't exceed our allocation.	Eric Anholt
	It takes (offset, size), not (offset, end).
2008-05-09	GEM: Separate the LRU into execution list and LRU list.	Eric Anholt
	Now, the LRU list has objects that are completely done rendering and ready to kick out, while the execution list has things with active rendering, which have associated cookies and reference counts on them.
2008-05-09	GEM: Clear obj_priv->agp_mem when we free it.	Eric Anholt
	Still managing to get something wrong with this, oopsing down in agp.
2008-05-09	GEM: Avoid leaking refs on target objects on presumed offset success.	Eric Anholt

2008-05-09	[gem] API cleanup. allocate->create unreference->close name->flink	Keith Packard
	Make the API names a bit more consistent.
2008-05-08	[i915] clean up whinging from checkpatch.pl	Keith Packard

2008-05-08	Clean up whinging from checkpatch.pl in drm_gem.c	Keith Packard
	Whitespace changes, a few too-long-lines and some extra braces.
2008-05-08	GEM: Fix oops on NULL dereference when we try clflushing when we don't need to.	Eric Anholt

2008-05-08	[intel-gem] Move domains to relocation records. add set_domain ioctl.	Keith Packard
	Domain information is about buffer relationships, not buffer contents. That means a relocation contains the domain information as it knows how the source buffer references the target buffer. This also adds the set_domain ioctl so that user space can move buffers to the cpu domain.
2008-05-07	GEM: fix testcases for new ioctl args.	Eric Anholt

2008-05-07	Apply a few stylistic cleanups to match kernel code.	Arjan van de Ven

2008-05-07	GEM: Wait for existing rendering to complete before writing relocation data.	Eric Anholt
	This should already have been generally safe since we don't change contents and put in new relocations between execbufs, so if we were writing in a new relocation then we'd already waited rendering to complete when we moved the target of the relocation. However, doing the right thing will be required if we do buffer reuse.
2008-05-07	GEM: Extend cache domain stuff for 965.	Eric Anholt
	One of our MI_FLUSH bits is reserved on 965, being always implied, and there's a vertex cache that was forgotten.
2008-05-06	[intel-GEM] ref count objects in gtt-lru.	Keith Packard
	If objects on the lru aren't ref counted, they'll get pulled from the gtt as soon as they are freed. This change does cause objects to get stuck in the gtt until they're forced out by new requests. The lru should get cleaned when the irq occurs.
2008-05-06	[intel-GEM] Add memory domain support.	Keith Packard
	Memory domains allow the kernel to track which caches to flush and how to move objects before buffer execution.
2008-05-06	Merge commit 'anholt/drm-gem' into drm-gem	Keith Packard

2008-05-06	Start coding up memory domains	Keith Packard

2008-05-06	GEM: Use irq-based fencing rather than syncing and evicting every exec.	Eric Anholt

2008-05-06	GEM: Skip relocation if presumed offset matches.	Eric Anholt

2008-05-06	GEM: Save the last ioremapped page for relocations in case we need it again.	Eric Anholt

2008-05-05	Dump last batch buffer when hardware lockup is detected.	Keith Packard

2008-05-05	Monitor ACTHD register while polling for idle ring.	Keith Packard
	When batch buffers are executing, the ring may be stuck for a long time. Monitor the ACTHD pointer which will show if the execution engine is actually hung.
2008-05-05	Unlock pages right after getting them.	Keith Packard
	pages come back from find_or_create_page locked, but must not stay locked for long. Unlock them immediately instead of waiting until we're done with them to avoid deadlock when applications try to touch them.
2008-05-05	Merge commit 'anholt/drm-gem' into drm-gem	Keith Packard
	Conflicts: linux-core/i915_gem.c
2008-05-05	GEM: Replace drm_memrange_for_each with just evicting what we brought in.	Eric Anholt
	I was wrong about how the data structure worked, and didn't care to fix it to support debugging code.
2008-05-05	Remove some debug messages.	Keith Packard

2008-05-05	Add object base to relocation store address.	Keith Packard
	The relocated value was being written to the wrong location, missing the object base address.
2008-05-05	Emit clflush and chipset flush when mapping objects to gtt	Keith Packard

2008-05-05	Correct execbuffer offset. Add memory barrier and chipset flush.	Keith Packard

2008-05-05	Add i915_dispatch_gem_execbuffer (broken).	Keith Packard
	This function submits a gem-based execbuffer to the ring. It doesn't work yet.
2008-05-02	Don't forget to set the memrange private, and reset ring on kernel entry.	Eric Anholt

2008-05-02	Don't include the tail guard memrange in foreach callbacking.	Eric Anholt

2008-05-02	Check for do_mmap errors	Keith Packard

2008-05-02	Add a bit of /proc/dri/*/gem support. Clean up some refcount/pagelock issues.	Keith Packard
	Track named objects in /proc/dri/0/gem_names. Track total object count in /proc/dri/0/gem_objects. Initialize device gem data. return -ENODEV for gem ioctls if the driver doesn't support gem. Call unlock_page when unbinding from gtt. Add numerous misssing calls to drm_gem_object_unreference.
2008-05-02	Add name/open ioctls, separate handle and pointer ref counts.	Keith Packard
	Names are just another unique integer set (from another idr object). Names are removed when the user refernces (handles) are all destroyed -- this required that handles for objects be counted separately from internal kernel references (so that we can tell when the handles are all gone).
