2008-06-13[intel-gem] throttle based on frames rather than time. Reduces jitter.Keith Packard
Record the last execbuffer sequence for each client. Record that sequence in the throttle ioctl as the 'throttle sequence'. Wait for the last throttle sequence in the throttle ioctl.
2008-06-13[intel-gem] Use a delayed_work instead of a timer + work_structKeith Packard
We want request retirement to occur about once a second when the request queue is non-empty. This was done with a timer that queued a work_struct, using a delayed_work instead makes a lot more sense.
2008-06-13[gem] Remove the interrupt handler for retiring requests.Eric Anholt
This was insufficient once we started masking interrupts to only when someone was waiting for them (and would thus retire requests themselves). It was replaced by the retire_timer.
2008-06-11[gem] Move potentially device-specific ioctls to the intel driver.Eric Anholt
This is the create (may want location flags), pread/pwrite/mmap (performance tuning hints), and set_domain (will 32 bits be enough for everyone?) ioctls. Left in the generic set are just flink/open/close. The 2D driver must be updated for this change, and API but not ABI is broken for 3D. The driver version is bumped to mark this.
2008-06-10[gem] Manage the ringbuffer from the kernel in the GEM case.Eric Anholt
This requires that the X Server use the execbuf interface for buffer submission, as it no longer has direct access to the ring. This is therefore a flag day for the gem interface. This also adds enter/leavevt ioctls for use by the X Server. These would get stubbed out in a modesetting implementation, but are required while in an environment where the device's state is only managed by the DRM while X has the VT.
2008-06-06[intel] remove settable use_mi_batchbuffer_startKeith Packard
The driver can know what hardware requires MI_BATCH_BUFFER vs MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.
2008-06-06[intel-gem] Use timers to retire requests periodically.Keith Packard
Without the user IRQ running constantly, there's no wakeup when the ring empties to go retire requests and free buffers. Use a 1 second timer to make that happen more often.
2008-06-06[intel] free the hardware status page at driver_unloadKeith Packard
This goes with the other hardware status page patch.
2008-06-06[intel-gem] Add explicit throttle ioctlKeith Packard
Instead of throttling and execbuffer time, have the application ask to throttle explicitly. This allows the throttle to happen less often, and without holding the DRM lock.
2008-06-06[intel] Allocate hardware status page at driver load timeKeith Packard
I couldn't get the re-allocated HWS to work on my 965GM, so I just gave up and made it persist across the lifetime of the driver instead.

2008-05-27[FreeBSD] Add vblank-rework support and get drivers building.Robert Noland
The i915 driver now works again.
2008-05-25[intel-gem] Add DRM_I915_GEM_BUSY ioctl to check for idle buffers.Keith Packard
This new ioctl returns whether re-using the buffer would force a wait.
2008-05-22[intel] Add debug code to verify the cached ring tail pointer.Keith Packard
Recording the tail pointer in a local variable improves performance, but if someone messes up and fails to reload at the right time, the driver will write commands to the wrong part of the ring and scramble execution badly. This change (available by setting I915_RING_VALIDATE to 1) checks to make sure the cached tail pointer matches the hardware tail pointer at each ring buffer addition, calling BUG_ON when that's not true.
2008-05-22[gem] Release GEM buffers from work task scheduled from IRQ.Eric Anholt
There are now 3 lists. Active is buffers currently in the ringbuffer. Flushing is not in the ringbuffer, but needs a flush before unbinding. Inactive is as before. This prevents object_free → unbind → wait_rendering → object_reference and a kernel oops about weird refcounting. This also avoids an synchronous extra flush and wait when freeing a buffer which had a write_domain set (such as a temporary rendered to and then from using the 2d engine). It will sit around on the flushing list until the appropriate flush gets emitted, or we need the GTT space for another operation.
2008-05-20[gem] Use a separate sequence number field from classic/ttmEric Anholt
This lets us get some qualities we desire, such as using the full 32-bit range (except zero), avoiding DRM_WAIT_ON, and a 1:1 mapping of active sequence numbers to request structs, which will be used soon for throttling and interrupt-driven list cleanup.
2008-05-15[gem] Rename the GTT LRU lists to active (executing) and inactive (idle).Eric Anholt
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.
2008-05-09GEM: 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.
2008-05-06GEM: Use irq-based fencing rather than syncing and evicting every exec.Eric Anholt
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.

2008-05-05Correct 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.
