2008-05-29[intel-gem] Write the presumed_offset back out after updating it.Eric Anholt
Otherwise, 965 constant state buffers get re-relocated every exec. Ouch.
2008-05-28[intel-gem] Clean up active/inactive/flushing list debugging.Keith Packard
2008-05-29modesetting: reorganise code into core and helper functions.Dave Airlie
This splits a lot of the core modesetting code out into a file of helper functions, that are only called from themselves and/or the driver. The driver gets called into more often or can call these functions from itself if it is a helper using driver. I've broken framebuffer resize doing this but I didn't like the API for that in any case.

2008-05-28i915: unmap BIOS when we're done with itJesse Barnes
At the moment, we only read it at startup time, so we can just unmap it there when we're done.

2008-05-27[BSD] Move unlock in drm_vm.c from accidental platform #ifdeffing.Owain Ainsworth
Also remove an unreachable unlock.

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
2008-05-26[intel-gem] Must hold DRM lock while setting object domainKeith Packard
Object domain transfer can involve adding flush ops to the request queue, and so the DRM lock must be held to avoid having the X server smash pointers badly.
2008-05-26[i915] leave interrupts masked off when not in use.Keith Packard
The interrupt enable register cannot be used to temporarily disable interrupts, instead use the interrupt mask register. Note that this change means that a pile of buffers will be left stuck on the chip as the final interrupts will not be recognized to come and drain things.
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.
2008-05-25[intel-gem] Compute npages instead of nbytes in flush_pwriteKeith Packard
i915_gem_flush_pwrite optimizes short writes to the buffer by clflushing only the modified pages, but it was miscomputing the number of pages.
2008-05-25[intel-gem] replace call to jiffies_to-msec with simple inlineKeith Packard
2008-05-23i915: do a better job of parsing VBIOS dataJesse Barnes
Add code to get panel modes from the VBIOS if present and check whether certain outputs exist. Should make our display detection code a little more robust.
2008-05-23drm_mode_debug_printmodeline doesn't need struct drm_device *Jesse Barnes
Makes printing modelines from some routines easier.
2008-05-22[intel-gem] Encourage multiple caches to hold read dataKeith Packard
When reading from multiple domains, allow each cache to continue to hold data until writes occur somewhere. This is done by first leaving the read_domains alone at bind time (presumably the CPU read cache contains valid data still) and then in set_domain, if no write_domain is specified, the new read domains are simply merged into the existing read domains. A huge comment was added above set_domain to explain how things are expected to work.
2008-05-22[gem] Use CPU domain for new or pageable objectsKeith Packard
Newly allocated objects need to be in the CPU domain as they've just been cleared by the CPU. Also, unmapping objects from the GTT needs to put them into the CPU domain, both to flush rendering as well as to ensure that any paging action gets flushed before we remap to the GTT.
2008-05-22[intel-gem] Force ring retire by emiting flush before user-interrupt.Keith Packard
Commands in the ring are parsed and started when the head pointer passes by them, but they are not necessarily finished until a MI_FLUSH happens. This patch inserts a flush after the execbuffer (the only place a flush wasn't already happening).
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[intel-gem] invalidate ring locals for pin/unpin/set_domain/free functionsKeith Packard
Ring locals must be reloaded from hardware in case the X server ran.
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.
2008-05-23r500: add two more register ranges for mesa driver to setupDave Airlie
2008-05-23drm: fix nouveau warningDave Airlie
2008-05-22i915: check dummy page before freeingHong Liu
The dummy read page will point to NULL if drm_bo_driver_init failed at firstopen (modeset is not enabled), and will cause kernel oops at subsequent drm_lastclose call, so be sure to check it.
2008-05-22i915: init bo mm at driver init only when modeset=1Hong Liu
To avoid bo memory manager being inited twice, it will be called at firstopen when modeset is not enabled.
2008-05-21[gem] Replace ring throttling hack with actual time measurement.Eric Anholt
2008-05-21[gem] Fix bad test for list_for_each completion.Eric Anholt
Since it's a circular list, the entry won't be NULL at termination.
2008-05-21[gem] Hold a reference on the object in i915_gem_wait_space.Eric Anholt
Otherwise, in the middle of the function called using it the last ref might disappear.
2008-05-21[intel-gem] invalidate ring locals for pin/unpin/set_domain/free functionsKeith Packard
Ring locals must be reloaded from hardware in case the X server ran.
2008-05-21rs690/r500: vblank support.Dave Airlie
The new display controller has the vblank interrupts in a different place. Add support for vbl interrupts for these chips
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.
2008-05-20[gem] Rename sequence numbers from "cookie" to "seqno"Eric Anholt
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.
2008-05-17r500: add more register ranges for Mesa driverDave Airlie
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
