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] 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).
2008-05-09GEM: 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] API cleanup. allocate->create unreference->close name->flinkKeith Packard
Make the API names a bit more consistent.
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.
2008-05-07GEM: 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.

2008-05-06GEM: Use irq-based fencing rather than syncing and evicting every exec.Eric Anholt
2008-05-05Dump last batch buffer when hardware lockup is detected.Keith Packard
2008-05-05Monitor 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.
2008-05-05Remove some debug messages.Keith Packard
2008-05-05Correct execbuffer offset. Add memory barrier and chipset flush.Keith Packard
2008-05-05Add i915_dispatch_gem_execbuffer (broken).Keith Packard
This function submits a gem-based execbuffer to the ring. It doesn't work yet.
2008-05-02Add 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).
2008-05-02Remove drm_driver argument to functions taking drm_gem_object.Keith Packard
Now that drm_gem_object has a drm_driver * in it, functions don't need both parameters.
2008-05-02Fix nouveau warning when returning pointers in uint64_t objects.Keith Packard
2008-05-01Add alignment to all aperture allocation requests.Keith Packard
When pinning buffers, or using execbuffer, allow the application to specify the necessary aperture allocation alignment constraints.
2008-05-01Fix gem ioctls to be 32/64-bit clean.Keith Packard
mixed 32/64 bit systems need 'special' help for ioctl where the user-space and kernel-space datatypes differ. Fixing the datatypes to be the same size, and align the same way for both 32 and 64-bit ppc and x86 environments will elimiante the need to have magic 32/64-bit ioctl translation code.

From Jesse and Zhenyu originally.
2008-04-20[I915] Handle tiled buffers in vblank taskletKeith Packard
The vblank tasklet update code must build 2D blt commands with the appropriate tiled flags.
2008-04-20On I965, use correct 3DSTATE_DRAWING_RECTANGLE command in vblankKeith Packard
The batchbuffer submission paths were fixed to use the 965-specific command, but the vblank tasklet was not. When the older version is sent, the 965 will lock up.

2008-03-31nouveau: fix return from function..Dave Airlie
dude kernel moduless use kernel errors :) this fixes an oops on init when this codepath hits.

- Note that this may not work for all nv86.
2008-03-30drm/r300: fix wait interface mixupDave Airlie
This interface was defined completely wrong, however userspace has only ever used 4 values from it (0x1, 0x2, 0x3 and 0x6), so fix the interface to do what userspace actually expected but define new defines for new users to use it properly.
2008-03-29r300: Correctly translate the value for the R300_CMD_WAIT command.Oliver McFadden
Previously, the R300_CMD_WAIT command would write the passed directly to the hardware. However this is incorrect because the R300_WAIT_* values used are internal interface values that do not map directly to the hardware. The new function I have added translates the R300_WAIT_* values into appropriate values for the hardware before writing the register. Thanks to John Bridgman for pointing this out. :-)
2008-03-25nouveau: nv20 bios does not initialise PTIMERStuart Bennett
The wait functions depend on PTIMER, so write the old (incorrect, but working) values for uninitialised hw

2008-03-24nv40: allocate massive amount of PRAMIN for grctx on all chipsets.Ben Skeggs
More or less a workaround for issues on some chipsets where a context switch results in critical data in PRAMIN being overwritten by the GPU. The correct fix is known, but may take some time before it's a feasible option.
