Eric Anholt 689548b527 intel-gem: Remove dead field from reverted changes. 2008-07-30 11:29:32 -07:00
Eric Anholt 33c8e03787 Revert "Rename drm_mm.c and its fuctions to drm_memrange."
This reverts commit 3ad8db2071.

We ended up not needing that namespace, and I'd rather not have the churn
for producing diffs.

Michel Dänzer 4be367b84b Reinstate dev->vblank_enabled[].
I incorrectly thought it was obsolete.

Michel Dänzer 205aff6a5c vblank-rework rework cleanups.
Remove some dead/obsolete code and make drm_update_vblank_count() static.

Michel Dänzer 014935b680 Remove obsolete dev->vblank_suspend[crtc] tests.
Caused drm_update_vblank_count() not to do its thing when called from
drm_modeset_ctl() -> drm_vblank_get().

The vblank functionality no longer needs to be suspended during a modeset, so
rename the field to vblank_inmodeset.

Jesse Barnes 2204f926ab Avoid incorrect vblank wakeups
The current code uses the hw vblank counter exclusively, which can lead
to wakeups during the active period rather than during the vblank period
if the hw counter counts displayed frames rather than vblank periods.

This change coverts the code over to using the counter while interrupts
are enabled, fixing that issue.  It also includes a couple of related
changes:  one to not enable the new enable/disable behavior until the
modeset ioctl is called (to preserve old client behavior) and another to
account for lost events due to mode setting with the new counter scheme.

BSD will require similar changes to its drm_irq.c code, but they should
be straightforward.

Eric Anholt b2606e325a [gem] Remove the drm_client_lock_take in set_domain.
We no longer need to use it to protect against shared ringbuffer access.
2008-06-11 16:19:23 -07:00
Eric Anholt 2655005762 [gem] Move potentially device-specific ioctls to the intel driver.
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.
2008-06-11 14:42:40 -07:00
Eric Anholt 2150da5d1a [gem] Manage the ringbuffer from the kernel in the GEM case.
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.

Michel Dänzer ba7263b8c2 vblank: Don't wait or update the counter while the CRTC is supposedly disabled.
Without kernel modesetting, this requires cooperation of the userspace
modesetting driver. We may have to leave the vblank interrupt enabled otherwise
to avoid problems.

Michel Dänzer 237172b767 vblank: Clean up compensation for spurious wraparounds of driver counter.
Only compensate when the driver counter actually appears to have moved
backwards.

The compensation deltas need to be incremental instead of absolute; drop the
vblank_offset field and just use atomic_sub().

Eric Anholt e10502002f [intel-gem] Replace idlelock usage with real lock acquisition. 2008-05-27 18:03:18 -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.

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 dafe48e623 GEM: Replace drm_memrange_for_each with just evicting what we brought in.
I was wrong about how the data structure worked, and didn't care to fix it

Keith Packard b6f173c430 Add i915_dispatch_gem_execbuffer (broken).
This function submits a gem-based execbuffer to the ring.
It doesn't work yet.

Keith Packard ab3549d133 Add a bit of /proc/dri/*/gem support. Clean up some refcount/pagelock issues.
Track named objects in /proc/dri/0/gem_names.
Track total object count in /proc/dri/0/gem_objects.
Initialize device gem data.
return -ENODEV for gem ioctls if the driver doesn't support gem.
Call unlock_page when unbinding from gtt.
Add numerous misssing calls to drm_gem_object_unreference.
2008-05-02 16:34:16 -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).
2008-05-02 12:29:17 -07:00
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.

krefs are way easier than a custom-coded spinlock+int combo.

Eric Anholt 3ad8db2071 Rename drm_mm.c and its fuctions to drm_memrange.
It's not really a graphics memory allocator, just something to track ranges
of address space.  It doesn't involve actual allocation, and was consuming
some desired namespace.

Dave Airlie 1f96e9a982 drm/pcigart: fix the pci gart to use the drm_pci wrapper.
This is the correct fix for the RS690 and hopefully the dma coherent work.

For now we limit everybody to a 32-bit DMA mask but it is possible for
RS690 to use a 40-bit DMA mask for the GART table itself,
and the PCIE cards can use 40-bits for the table entries.

Jesse Barnes 79d6928520 Fix vblank enable/disable callbacks
There were two problems with the existing callback code:  the vblank
enable callback happened multiple times per disable, making drivers more
complex than they had to be, and there was a race between the final
decrement of the vblank usage counter and the next enable call, which
could have resulted in a put->schedule disable->get->enable->disable
sequence, which would be bad.

So add a new vblank_enabled array to track vblank enable on per-pipe
basis, and add a lock to protect it along with the refcount +
enable/disable calls to fix the race.

Kristian Høgsberg 68cdcda1ea Add new shared header file drm_internal.h.
This header file is shared across linux and bsd, but is not installed
for user space to access.  It's the place to put prototypes and data
types that aren't platform or chipset specific, but still internal to
the drm.

needed instead of passing it around.

Kristian Høgsberg a69c85fec8 Drop destroy ioctls for fences and buffer objects.
We now always create a drm_ref_object for user objects and this is then the only
things that holds a reference to the user object.  This way unreference on will
destroy the user object when the last drm_ref_object goes way.

Dave Airlie bc5423f168 drm_sysfs: update sysfs code from kernel 2007-09-20 14:01:29 +10:00
Ben Skeggs 97770db720 nouveau: Various internal and external API changes
1. DRM_NOUVEAU_GPUOBJ_FREE
	Used to free GPU objects.  The obvious usage case is for Gr objects,
	but notifiers can also be destroyed in the same way.

	GPU objects gain a destructor method and private data fields with
	this change, so other specialised cases (like notifiers) can be
	implemented on top of gpuobjs.

2. DRM_NOUVEAU_CHANNEL_FREE

3. DRM_NOUVEAU_CARD_INIT
	Ideally we'd do init during module load, but this isn't currently
	possible.  Doing init during firstopen() is bad as X has a love of
	opening/closing the DRM many times during startup.  Once the
	modesetting-101 branch is merged this can go away.

	IRQs are enabled in nouveau_card_init() now, rather than having the
	X server call drmCtlInstHandler().  We'll need this for when we give
	the kernel module its own channel.

4. DRM_NOUVEAU_GETPARAM
	Add CHIPSET_ID value, which will return the chipset id derived
	from NV_PMC_BOOT_0.

4. Use list_* in a few places, rather than home-brewed stuff.
