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[libdrm/intel] Eliminate extra dri_gem_bo_bucket_entry structureKeith Packard
Place the buffer reuse links right into the dri_bo_gem object.
2008-06-06[libdrm/intel] Remove unused intel_validate_entry structureKeith Packard
2008-06-06[libdrm/intel] Reuse entire dri_bo_gem structureKeith Packard
The code was discarding the dri_bo_gem structure and saving only the kernel handle. This lost the mmap address, causing pain when the next buffer user wanted to map the buffer.
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.
2008-06-06Ignore X server provided mmio addressKeith Packard
2008-06-06[intel-gem] Dump error status on wait_request failureKeith Packard
2008-06-05Add a function to bufmgr_fake to evict all buffers in the GTT.Eric Anholt
This will be used by the X Server for VT switch.
2008-06-03Drop struct_mutex while waiting in drm_client_lock_takeKeith Packard
struct_mutex cannot be held while blocking on DRM lock.
2008-06-03Fix libdrm to actually include the new code instead of just building it.Eric Anholt
2008-06-03Fix and hook up bufmgr code to the build.Eric Anholt
2008-06-03Import bufmgr code to libdrm. Not yet hooked up to the build.Eric Anholt
2008-06-02[intel-gem] reloc_and_validate_object → object_bind_and_relocateKeith Packard
Just renaming this function and related parameters to match terminology used elsewhere in the driver.
2008-06-02[intel-gem] Propagate set_domain errors.Keith Packard
set_domain can block waiting for rendering to complete. If that process is interrupted by a signal, it can return -EINTR. Catch this error in all callers and correctly deal with the result.

2008-05-30[intel-gem] Only update obj->write_domain if we're actually changing it.Eric Anholt
The problem was revealed where on 965, the display list vertex buffer would see: create -> (CPU, CPU) set_domain (CPU, CPU) -> (CPU, CPU) set_comain (CPU, 0) -> (CPU, 0) (no clflush occurred) execbuf (GPU, 0) -> (CPU+GPU, 0) (still no clflush) instead of: create -> (CPU, CPU) set_domain (CPU, CPU) -> (CPU, CPU) set_comain (CPU, 0) -> (CPU, CPU) execbuf (GPU, 0) -> (CPU+GPU, 0) (clflushed)
2008-05-30[intel-gem] Add an option to check GTT versus CPU coherency at execbuf time.Eric Anholt

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

2008-05-27[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
2008-05-22[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.

2008-05-21[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.
