Michel Dänzer 3d5d41fa98 i915: Fix handling of breadcrumb counter wraparounds. 2007-06-15 17:13:11 +02:00
Jesse Barnes b06268294a Comment new vblank routines and fixup several issues:
- use correct refcount variable in get/put routines
  - extract counter update from drm_vblank_get
  - make signal handling callback per-crtc
  - update interrupt handling logic, drivers should use drm_handle_vblank
  - move wakeup and counter update logic to new drm_handle_vblank routine
  - fixup usage of get/put in light of counter update extraction
  - fix longstanding bug in signal code, update pending counter only
    *after* we're sure we'll setup signal handling
2007-06-14 11:32:31 -07:00
Jesse Barnes ca47fa90b7 Update vblank code:
- move pre/post modeset ioctl to core
  - fixup i915 buffer swap
  - fix outstanding signal count code
  - create new core vblank init routine
  - test (works with glxgears)
  - simplify i915 interrupt handler

Jesse Barnes db689c7b95 Initial checkin of vblank rework. Code attempts to reduce the number
of vblank interrupt in order to save power.

Thomas Hellstrom b6b5df24b9 Try to make buffer object / fence object ioctl args 64-bit safe.
Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.
64-bit wide buffer object flag member.

Wang Zhenyu 109e2a10f2 Add support for the G33, Q33, and Q35 chipsets.
These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory.  So, we have the X Server allocate that memory and tell
us the address, instead.

Jesse Barnes b7bf317f42 Merge branch 'modesetting-101' of git+ssh://git.freedesktop.org/git/mesa/drm into origin/modesetting-101
Conflicts:

	linux-core/drm_crtc.c
	linux-core/drm_fb.c

Lots of changes to merge with alanh's latest stuff:
  o fix use of fb->pitch now that it has the right value
  o add new helper for finding the CRTC given an FB
  o fix new fb_probe/fb_remove functions to take a CRTC
  o fixup callers of new FB routines
  o port drm_fb changes to intel_fb
  o check for errors after creating fb buffer object
  o go back to using cfb_imageblit since the accel stubs aren't ready
2007-05-17 10:35:07 -07:00
Jesse Barnes a18b4befb9 Fix FB pitch value (we had it wrong and were working around it in a few
places).
Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver.  This will allow acceleration and better handling
of the command stream.

David Airlie cc471a361f i915/drm: clean up a lot of the i915/drm startup/teardown sequences
When the kernel driver is loaded it sets up a lot of stuff..
it tears down the same stuff on unload.

This add a new map type called DRM_DRIVER which means the driver will clean the mapping up
and fix up the map cleaner

Michel Dänzer a33859184a i915: Eliminate dev_priv->current_page.
Always use dev_priv->sarea_priv->pf_current_page directly. This allows clients
to modify it as well while they hold the HW lock, e.g. in order to sync pages
between pipes.
2007-02-28 17:48:56 +01:00
Michel Dänzer 1cdc1b6fba i915: Don't emit waits for pending flips before emitting synchronous flips.
The assumption is that synchronous flips are not isolated usually, and waiting
for all of them could result in stalling the pipeline for long periods of time.

Also use i915_emit_mi_flush() instead of an old-fashioned way to achieve the
same effect.
2007-02-28 15:23:19 +01:00
Michel Dänzer 1a0d890a42 i915: Add support for scheduled buffer swaps to be done as flips.
Unfortunately, emitting asynchronous flips during vertical blank results in
tearing. So we have to wait for the previous vertical blank and emit a
synchronous flip.
2007-02-22 17:21:18 +01:00
Michel Dänzer 6f89584e13 i915: Improved page flipping support, including triple buffering.
Pages are tracked independently on each pipe.

Bump the minor version for 3D clients to know page flipping is usable, and
bump driver date.
2007-02-19 15:08:40 +01:00
Michel Dänzer 34aa3393d0 i915: Page flipping enhancements.
Leave it to the client to wait for the flip to complete when necessary,
but wait for a previous flip to complete before emitting another one. This
should help avoid unnecessary stalling of the ring due to pending flips.

Call i915_do_cleanup_pageflip() unconditionally in preclose.

Thomas Hellstrom 53aee3122a I915 accelerated blit copy functional.
Fixed - to System memory copies are implemented by
flipping in a cache-coherent TTM,
blitting to it, and then flipping it out.

Eric Anholt 8918748058 Add chip family flags to i915 driver, and fix a missing '"' in mach64 ID list. 2007-02-07 21:26:01 -08:00
Thomas Hellstrom 609e3b0375 Implement a policy for selecting memory types. 2007-02-06 14:20:33 +01:00
Thomas Hellstrom 3024f23c65 memory manager: Make device driver aware of different memory types.
Memory types are either fixed (on-card or pre-bound AGP) or not fixed
(dynamically bound) to an aperture. They also carry information about:

1) Whether they can be mapped cached.
2) Whether they are at all mappable.
3) Whether they need an ioremap to be accessible from kernel space.

In this way VRAM memory and, for example, pre-bound AGP appear
identical to the memory manager.

This also makes support for unmappable VRAM simple to implement.

Wang Zhenyu 2851c9f5c6 Bump i915 minor for ARB_OC ioctl 2007-01-06 16:26:54 -08:00
Thomas Hellstrom 10150df02b Simplify the AGP backend interface somewhat.
Fix buffer bound caching policy changing, Allow
on-the-fly changing of caching policy on bound buffers if the hardware
supports it.

Allow drivers to use driver-specific AGP memory types for TTM AGP pages.
Will make AGP drivers much easier to migrate.

Michel Dänzer da75d59cd6 i915: Add ioctl for scheduling buffer swaps at vertical blanks.

2006-09-29 12:55:08 +02:00
Michel Dänzer 596d7e9984 Add support for secondary vertical blank interrupt to i915 driver.
When the vertical blank interrupt is enabled for both pipes, pipe A is
considered primary and pipe B secondary. When it's only enabled for one pipe,
it's always considered primary for backwards compatibility.

Thomas Hellstrom e089de33e8 i915 fence object driver implementing 2 fence object types:
0x00 EXE fence. Signals when command stream interpreter has reached the point
where the fence was emitted.
0x01 FLUSH fence. Signals when command stream interpreter has reached the point
where the fence was emitted, and all previous drawing operations have been
completed and flushed.
Implements busy wait (for fastest response time / high CPU) and
lazy wait (User interrupt or timer driven).

Eric Anholt c6344e8df5 Assert an MIT copyright on sis_drm.h, since one was lacking and I created
that particular file. Its contents have changed a good bit since the
    original sis code, and the original sis code didn't care much about
    attribution since it routinely disclaims Precision Insight/VA Linux
    from responsibility. Also, adjust formatting around license headers
    (have a comment open immediately before the "Copyright" line, not as a
    runon of any previous comments) for automatic processing into FreeBSD,
    where /*- is used to signal the beginning of license headers for
    automatic compilation of license lists.

Eric Anholt c789ea1521 Rename the driver hooks in the DRM to something a little more
understandable: preinit -> load postinit -> (removed) presetup ->
    firstopen postsetup -> (removed) open_helper -> open prerelease ->
    preclose free_filp_priv -> postclose pretakedown -> lastclose
    postcleanup -> unload release -> reclaim_buffers_locked version ->
    (removed)
postinit and version were replaced with generic code in the Linux DRM
    (drivers now set their version numbers and description in the driver
    structure, like on BSD). postsetup wasn't used at all. Fixes the savage
    hooks for initializing and tearing down mappings at the right times.
    Testing involved at least starting X, running glxgears, killing
    glxgears, exiting X, and repeating.

Alan Hourihane 45f1db8db9 Re-implement the power management.
There's two choices when fb is or isn't loaded as we treat ourselves as a
    PCI driver in the latter case.
If we are a PCI driver, then register the suspend/resume functions
    directly. If not, then we register as a sysdev and pick up the
    suspend/resume actions and pump them down into a generic *power
    function.
It'll be nice when this little mess is sorted out with regard to being a
    real PCI driver ;-/

Ian Romanick 4a84416c45 Modify drm_driver::device_is_agp to return a tri-state value to indicate

    "AGP" (even the PCI-e devices).

Eric Anholt ec111d70fe Convert BSD code to mostly use bus_dma, the dma abstraction for dealing
with IOMMUs and such. There is one usage of the forbidden vtophys()
    left in drm_scatter.c which will be fixed up soon. This required a KPI
    change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
    keeps track of os-specific bits, rather than just passing around the
    vaddr/busaddr/size.
