Robert Noland 8cd045079e [FreeBSD] Add vblank-rework support and get drivers building.
The i915 driver now works again.
2008-05-27 14:25:20 -07:00
Keith Packard d434b64f6a [i915] leave interrupts masked off when not in use.
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.
2008-05-26 03:25:16 -07:00
Keith Packard 7cf3fd29fe [intel-gem] Add DRM_I915_GEM_BUSY ioctl to check for idle buffers.
This new ioctl returns whether re-using the buffer would force a wait.
2008-05-25 20:45:20 -07:00
Jesse Barnes 9fc4ea5c00 i915: do a better job of parsing VBIOS data
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.
2008-05-23 18:42:47 -07:00
Keith Packard a51c3a76ff [intel] Add debug code to verify the cached ring tail pointer.
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 22:00:21 -07:00
Eric Anholt 5e662f90d1 [gem] Release GEM buffers from work task scheduled from IRQ.
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.

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.
2008-05-20 14:16:26 -07:00
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
Jesse Barnes ee631e1b86 i915: register definition & header file cleanup
It would be nice if one day the DRM driver was the canonical source for
register definitions and core macros.  To that end, this patch cleans
things up quite a bit, removing redundant definitions (some with
different names referring to the same register) and generally tidying up
the header file.
2008-05-13 14:44:17 -07:00
Hong Liu af60d87869 fix G33 hardware status page in modeset
We need to alloc a hw status page bo for G33 if modeset is enabled since the 2D
driver can't alloc gfx memory when working in drm modeset.
2008-05-12 12:04:02 -07:00
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.
2008-05-11 00:10:16 -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.

Jesse Barnes 12725a37af i915: add basic VBT support

2008-05-09 14:19:00 -07:00
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.

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.

Jesse Barnes c7ee6cc269 Remove broken 'in vblank' accounting
We need to return an accurate vblank count to the callers of
->get_vblank_counter, and in the Intel case the actual frame count
register isn't udpated until the next active line is displayed, so we
need to return one more than the frame count register if we're currently
in a vblank period.

However, none of the various ways of doing this is working yet, so
disable the logic for now.  This may result in a few missed events, but
should fix the hangs some people have seen due to the current code
tripping the wraparound logic in drm_update_vblank_count.

Keith Packard d1187641d6 Rename inappropriately named 'mask' fields to 'proposed_flags' instead.
Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.

This affects the API, but not ABI of the user-mode interface.

Jesse Barnes 852232fb80 Remove plane->pipe mapping from SAREA private after all
We can figure out which pipe a given plane is mapped to by looking at the
display control registers instead of tracking it in a new SAREA private field.
If this becomes a performance problem, we could move to an ioctl based solution
by adding a new parameter for the DDX to set (defaulting to the old behavior if
the param was never set of course).

Jesse Barnes 3cb8acd5ab Disambiguate planes & pipes for swap operations
This mod makes the SAREA track plane to pipe mappings and corrects the name of
the plane info variables (they were mislabeled as pipe info since until now all
code assumed a direct mapping between planes and pipes).

It also updates the flip ioctl argument to take a set of planes rather than
pipes, since planes are flipped while pipes generate vblank events.

Eric Anholt 5b38e13416 Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.
The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures.  This also means that XFree86 4.2.0 support for i810 DRM
is lost.

Eric Anholt c1119b1b09 Replace filp in ioctl arguments with drm_file *file_priv.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

Jesse Barnes 97dcd7fd25 more vblank rework
- use a timer for disabling vblank events to avoid enable/disable calls too
    often
  - make i915 work with pre-965 chips again (would like to structure this
    better, but this hack works on my test system)
