Eric Anholt d6f7968577 [gem] Replace ring throttling hack with actual time measurement. 2008-05-21 16:40:14 -07:00
Eric Anholt af8e087157 [gem] Use a separate sequence number field from classic/ttm
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.

Eric Anholt ab36a6f983 [gem] Rename sequence numbers from "cookie" to "seqno" 2008-05-20 10:53:10 -07:00
Eric Anholt 6c3ac484b0 [gem] Clean up active/inactive list handling using helper functions.
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.

Eric Anholt 7dced2f33a [gem] Hold dev->struct_mutex to protect structure data. 2008-05-15 18:45:23 -07:00
Eric Anholt 3ab152da66 [gem] Rename the GTT LRU lists to active (executing) and inactive (idle). 2008-05-15 11:59:58 -07:00
Eric Anholt f650d7240a [GEM] Typo (and thinking) fixes in drm-gem.txt and doxygen. 2008-05-12 13:17:01 -07:00
Keith Packard 7e7ea313c4 [intel] When polling for ring space, sleep for a lot longer (10ms)
If the ring is full, the engine will surely be running for more than 10ms.

Keith Packard ff39db099b [GEM] Make pread/pwrite manage memory domains. No luck with movnti though.
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.

Keith Packard a37ac493da [intel-GEM] Clean up GEM ioctl naming.
Rename 'validate_entry' to 'exec_object', then clean up some field names in
structures (renaming buffer_offset to just offset, for example).
2008-05-10 21:04:18 -07:00
Eric Anholt c5c59eab80 GEM: Separate the LRU into execution list and LRU list.
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.

Keith Packard 1e26ca44c9 [gem] API cleanup. allocate->create unreference->close name->flink
Make the API names a bit more consistent.

Keith Packard 9af4c49743 [intel-gem] Move domains to relocation records. add set_domain ioctl.
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.

Eric Anholt 5f5f01ed91 GEM: Extend cache domain stuff for 965.
One of our MI_FLUSH bits is reserved on 965, being always implied, and there's
a vertex cache that was forgotten.

Keith Packard 6a6c37af9e [intel-GEM] ref count objects in gtt-lru.
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.

Keith Packard 91cba3ae17 Dump last batch buffer when hardware lockup is detected. 2008-05-05 22:10:02 -07:00
Keith Packard ed6657fa8e Monitor ACTHD register while polling for idle ring.
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.

Keith Packard d59a9300ec Remove some debug messages. 2008-05-05 14:32:01 -07:00
Keith Packard 4511e6cd80 Correct execbuffer offset. Add memory barrier and chipset flush. 2008-05-05 11:27:06 -07:00
Keith Packard b6f173c430 Add i915_dispatch_gem_execbuffer (broken).
This function submits a gem-based execbuffer to the ring.
It doesn't work yet.
2008-05-05 10:51:49 -07:00
Keith Packard 39e20bcd5f Add name/open ioctls, separate handle and pointer ref counts.
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).

Keith Packard 49e8e3372a Remove drm_driver argument to functions taking drm_gem_object.
Now that drm_gem_object has a drm_driver * in it, functions don't need both
parameters.

Keith Packard 0d547c9ed9 Add alignment to all aperture allocation requests.
When pinning buffers, or using execbuffer, allow the application to specify
the necessary aperture allocation alignment constraints.

Keith Packard 30efad5113 Fix gem ioctls to be 32/64-bit clean.
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.

Keith Packard 21dbba5a22 On I965, use correct 3DSTATE_DRAWING_RECTANGLE command in vblank
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.
